- the second detection element 6 may be located at the front of the ride-on lawnmower or at the highest point of the mower.
- the second detection element 6 acquires real-time data in the area in front of and to the left and right sides of the riding lawnmower, and determines the presence of users or obstacles based on this data. This area is within the sensor's coverage range. Specifically, when the lawnmower is moving forward, the width of the acquired frontal area is greater than the width of the left and right side areas. It is understood that during forward movement, the main factors affecting the lawnmower's movement occur in the front, not the left and right sides; therefore, a larger safety width is required in the front. As shown in Figure 12, width P is less than width Q.
- the second detection element 6 is used to acquire data in real time in the areas in front of, behind, and to the left and right sides of the riding lawnmower to determine whether there are users or obstacles.
- the ride-on automatic lawnmower further includes a second detection element 6, disposed around the lawnmower, configured to acquire second detection data regarding the presence of a user or obstacle around the ride-on lawnmower, and send this data to the controller 5.
- the second detection element 6 may be disposed around the perimeter of the ride-on lawnmower or at the highest point of the mower. It should be noted that since the second detection element 6 may have blind spots, multiple second detection elements 6 may be provided, such as four or more.
- the automatic lawnmower in automatic mode, if the absence of a user or obstacle is detected based on second detection data, the automatic lawnmower is controlled to automatically travel along a planned path.
- the automatic lawnmower in automatic mode, if the presence of a user or obstacle is detected based on second detection data, and the absence of a user or obstacle is detected after a first preset time period, the automatic lawnmower is controlled to automatically travel along a planned path, at least in response to the change in detection data from the detection of the presence of a user or obstacle to the absence of a user or obstacle within the first preset time period.
- the first preset time period can be set according to actual needs, for example, it can be set to 20 seconds, 30 seconds, etc.
- the automatic lawnmower can respond to multiple commands to control the ride-on lawnmower to automatically travel along a planned path. For example, in automatic mode, after receiving a user command, and if second detection data indicates that there is no user or obstacle, the automatic lawnmower can be controlled to automatically travel along the planned path.
- the automatic lawnmower in automatic mode, after receiving a user command, if the presence of a user or obstacle is detected based on second detection data, and if the absence of a user or obstacle is detected after a first preset time period, then the automatic lawnmower can be controlled to travel along a planned path, at least in response to the change in detection data from the detection of the presence of a user or obstacle to the absence of a user or obstacle within the first preset time period. Multiple commands are used to control the ride-on lawnmower to travel automatically along the planned path, ensuring the safety of the lawnmower and nearby users.
- the second detection data detects a change in the detection data from the presence of a user to the absence of a user, it indicates that the user on the ride-on lawnmower has moved away from the lawnmower, preventing the user from operating the lawnmower while standing on it.
- the user can first stand in the driving position of the ride-on lawnmower, turn on the power switch on the control panel to start the ride-on lawnmower, and then leave the driving position.
- the controller 5 determines that there is no user on the ride-on lawnmower based on the first detection data from the first detection element 2, and initially identifies the presence of a user or obstacle based on the second detection element 6. After 30 seconds, the second detection element 6 identifies that there is no user or obstacle, and controls the ride-on lawnmower to automatically travel along the planned path.
- the automatic lawnmower will issue a voice command or send a notification message to the user's app to remind the user to leave. For example, if the first detection data indicates no user is on the lawnmower, but the second detection data indicates a user is present in the direction of the lawnmower's planned path, the automatic lawnmower will issue a voice command or send a notification message to the user's app to remind the user to leave, thus facilitating quick start of the lawnmower.
- the presence of a user on the automatic lawnmower can be determined by the following methods, or by a combination of the following methods. Of course, each method can be combined with the other implementations described above.
- the ride-on automatic lawnmower is equipped with a carrier for carrying a user.
- a user is detected on the carrier based on first detection data, it is determined that a user is on the lawnmower; when the first detection data indicates that no user is on the carrier, it is determined that no user is on the automatic lawnmower, thus ensuring the safety of the lawnmower and nearby users, or improving the working efficiency of the lawnmower.
- the first detection element 2 can be mounted on the carrier. Alternatively, it can be mounted at other locations that can detect whether a user is present on the carrier.
- the first detection element 2 may specifically include electronic devices or structural switches such as pressure sensors, infrared sensors, Hall effect sensors, and vision sensors.
- the carrier may include a driver's seat for the user to sit on or a standing platform for the user to stand on. Furthermore, the first detection element 2 can also detect whether the human-machine interface module (which may also be a user interface or a joystick) is triggered, allowing the user to confirm whether a user is present on the carrier. If, at least according to the first detection element 2, no user is detected on the carrier, the ride-on lawnmower is controlled to enter automatic mode. When the lawnmower is in automatic mode, in response to the detection of a user on the carrier based on the first detection data, the automatic lawnmower is controlled to exit automatic mode. This enables accurate and rapid determination of whether a user is present on the ride-on lawnmower.
- the carrier includes at least two position states: a folded state and an unfolded state.
- the first detection element 2 may be a Hall sensor.
- the controller is configured to: determine that a user is present on the carrier when the carrier is in the unfolded state based on the first detection data; and control the automatic lawnmower to enter manual mode at least in response to detecting the presence of a user on the automatic lawnmower.
- the carrier is in the folded state based on the first detection data, determine that no user is present on the carrier; and control the automatic lawnmower to enter automatic mode at least in response to detecting the absence of a user on the automatic lawnmower.
- the driver's seat includes a seat surface 22 and a backrest 21.
- the controller is configured to: in response to detecting a change in the position of the seat surface and backrest from unfolded to folded, control the automatic lawnmower to exit manual mode or enter standby mode; and in response to detecting a change in the position of the seat surface and backrest from folded to unfolded, control the automatic lawnmower to exit automatic mode or enter standby mode.
- the driver's seat is in the folded state
- Figure 9 the driver's seat is in the unfolded state.
- the carrier includes a platform 23, and the controller is configured to: control the automatic lawnmower to exit manual mode in response to detecting a change in the position of the platform from unfolded to folded; and control the automatic lawnmower to exit automatic mode in response to detecting a change in the position of the seat and backrest from folded to unfolded.
- the platform is in the folded state
- the platform is in the unfolded state.
- the first detection element 2 includes a pressure detection sensor disposed on the support member.
- the pressure detection sensor is configured to acquire the pressure value on the support member, and the first detection data is the pressure borne by the support member.
- the pressure is determined to be greater than or equal to a preset pressure threshold based on the first detection data, it is determined that a user is present on the support member; when the pressure is determined to be less than the preset pressure threshold based on the first detection data, it is determined that no user is present on the support member.
- the pressure detection sensor can be a sensor or a switch, and can output a 0 or 1 signal, where 1 indicates the presence of a user and 0 indicates the absence of a user.
- the controller 5 receives the pressure value of the driver's seat from the pressure detection sensor, it determines whether the pressure value is greater than a preset pressure threshold. If the pressure value is greater than the preset pressure threshold, it is determined that a user is present in the driver's seat; if the pressure value is less than or equal to the preset pressure threshold, it is determined that no user is present in the driver's seat, or the system continues to detect whether a user is present in the driver's seat. In this way, by detecting the pressure value on the driver's seat, it is possible to accurately and quickly determine whether a user is present on the ride-on lawnmower.
- the human-machine interface module includes at least two position states: a folded state and an unfolded state. At least in response to determining, based on position state information, that the carrier or the human-machine interface module is in the folded state, the automatic lawnmower is controlled to enter automatic mode. In automatic mode, in response to receiving a user command, the automatic lawnmower is controlled to automatically travel along a planned path. In automatic mode, by controlling these modules to retract, the machine's volume in space is reduced, thereby improving its passability and obstacle-crossing ability in special scenarios, such as narrow spaces and scenarios with low branches, making its operating scenarios more diverse.
- the automatic lawnmower in response to detection data indicating that the carrier or human-machine interface module is in an deployed state, the automatic lawnmower is controlled to exit automatic mode or enter manual mode.
- the automatic lawnmower when the carrier or human-machine operation module is in the unfolded state, the automatic lawnmower has a first dimension; when the carrier or human-machine operation module is in the folded state, the automatic lawnmower has a second dimension, the first dimension being larger than the second dimension, and the first dimension and the second dimension being the dimensions of the automatic lawnmower in any identical direction in space.
- automatic lawnmowers can be equipped with only one of the aforementioned first detection elements, or multiple first detection elements can be installed simultaneously.
- a pressure sensor acting as a third detection element
- a Hall sensor acting as a second detection element
- the automatic lawnmower upon determining that the carrier component is in the extended state and the pressure is greater than a preset pressure threshold, the automatic lawnmower is controlled to enter manual mode; upon determining that the carrier component is in the retracted state and the pressure is less than the preset pressure threshold, the automatic lawnmower is controlled to enter automatic mode.
- the positioning sensor 1 on the ride-on lawnmower can be a device that can assist in acquiring information about the environment ahead, such as vision, and determine whether there are obstacles ahead based on the information about the environment ahead identified by the positioning sensor.
- the automatic lawnmower when the automatic lawnmower is in manual or automatic mode, it may encounter abnormal situations. In response to these abnormal situations, the lawnmower often performs different control actions as described below to ensure the safety of the lawnmower and nearby users, or to improve the lawnmower's working efficiency. Of course, each of these actions can be combined with other implementations described above.
- the automatic lawnmower may further include: an anomaly detection sensor configured to acquire at least environmental information in the direction of movement of the automatic lawnmower or to acquire motion posture information of the automatic lawnmower.
- the controller is further configured to: determine, based on first detection data, that a user is present on the lawnmower; determine, based on information detected by the anomaly detection sensor, that the automatic lawnmower is about to or has already experienced an anomaly; and, in manual mode, control the lawnmower to exit manual mode in response to detecting that no user is present on the lawnmower for a continuous fourth preset time period, and that the lawnmower is about to or has already experienced an anomaly.
- the anomaly detection sensor may be a camera configured to detect whether the lawnmower is in a bumpy state or whether there is an uneven, bumpy road ahead.
- manual mode when abnormal conditions such as bumps are detected, if the duration of the user leaving the lawnmower exceeds the normal time range for bouncing and being airborne (i.e., greater than or equal to the fourth preset time period), it is determined that the user has completely left the seat.
- the lawnmower is controlled to exit manual mode to ensure the safety of users near the lawnmower. If the duration is short (i.e., less than the fourth preset time period, for example, less than 5 seconds), the lawnmower remains in manual mode, thus avoiding misinterpreting a brief bounce from the seat as an exit from manual mode. By accurately identifying the user's riding status, the stability of operating the lawnmower under abnormal conditions is ensured. Furthermore, by setting a time range, it is possible to avoid incorrect exits from manual mode due to brief bouncing and being airborne, improving the accuracy of the lawnmower in identifying the user's riding status and enhancing the user experience. For specific abnormal detection methods, please refer to the relevant content at the end of this document.
- the system in manual mode, in response to the detection of no user on the automatic lawnmower within a fifth preset time period, the system is controlled to exit manual mode.
- This fifth preset time period is longer than the fourth preset time period. If no user is detected for an extended period, it indicates that the user has likely left the lawnmower, and manual mode needs to be exited.
- the fifth preset time period is 10 seconds.
- the specific time values mentioned above are merely illustrative examples and should not be construed as limiting the time periods in this application's implementation. This application's implementation only needs to satisfy the aforementioned time relationships.
- the automatic lawnmower in manual mode, as the lawnmower moves forward, in response to the detection of an obstacle in front of the automatic lawnmower based on second detection data, or in response to the detection of an obstacle in front of the automatic lawnmower based on a positioning sensor, the automatic lawnmower is controlled to maintain its driving path or operating state. That is, in manual mode, the lawnmower primarily relies on manual remote control by the user, rather than other sensors. This prevents the lawnmower from exhibiting abnormal reactions such as yaw due to short-term anomalies in sensor-collected data, thus avoiding startling the user.
- the controller 5 when the controller 5 receives detection data of a user or obstacle from the second detection element 6 or the positioning sensor 1, it can output a reminder message to the user to prevent the ride-on lawnmower from colliding with the obstacle due to the user's lack of awareness. This could be done by triggering an alarm on the ride-on lawnmower, displaying a text reminder message about the obstacle on the control panel, or, in certain special circumstances, such as when the lawnmower is very close to an obstacle but no user-induced path-changing operation is detected, controlling the lawnmower to brake suddenly.
- the controller 5 can record the location information of the user or obstacle and update the map, for example, by marking the obstacle on the map. This improves the safety of the ride-on lawnmower and the user experience.
- the automatic lawnmower in response to the detection of an obstacle at least in the reverse direction based on second detection data, or in response to the detection of an obstacle in the reverse direction based on a positioning sensor, the automatic lawnmower is controlled to issue an alarm or send a notification message to the user. This prevents the user from colliding with pedestrians or obstacles behind them in time, thus avoiding unsafe situations.
- the lawnmower can be controlled to exit manual mode. This prevents unsafe situations where the lawnmower collide with nearby users due to user inattention.
- the controller 5 issues a locking command to the motion adjustment unit 4 or a stop cutting command to the cutting unit 3.
- the controller 5 may issue a locking command to the motion adjustment unit 4 so that the mower cannot be controlled to move according to the driving direction input by the motion adjustment unit 4, or issue a stop cutting command to the cutting unit 3 so that the cutting unit 3 stops performing the mowing operation.
- the lawnmower in automatic mode, during the automatic movement of the ride-on lawnmower along a planned path, if an obstacle is detected in front of the lawnmower within a second preset time period, the lawnmower is controlled to terminate the task.
- This second preset time period is shorter than a first preset time period. Controlling the second preset time period to be shorter than the first preset time period ensures that the lawnmower can start normally and perform the mowing work. This is because if the second preset time period is longer than the first preset time period, the response time required for obstacle detection becomes longer, which may lead to the inability to terminate the task in time, resulting in unsafe situations such as collisions with obstacles.
- the second preset time period can be set according to actual needs, such as 10 seconds, 15 seconds, or a shorter time period than the first preset time period. Furthermore, when a contact collision is detected with the ride-on lawnmower, it will be controlled to stop moving.
- the ride-on lawnmower also includes a standby mode, where the controller 5 is in a state where the task process is interrupted or terminated.
- the controller 5 will acquire, in real-time or intermittently, second detection data from the second detection element 6 regarding whether there are obstacles in the direction the lawnmower is moving, or acquisition data from the positioning sensor 1 regarding whether there are obstacles in front of the lawnmower.
- it is determined that an obstacle is continuously detected within a second preset time period, it indicates that the lawnmower has detected the obstacle for an extended period and may be unable to avoid it.
- the controller can control the ride-on lawnmower to terminate its movement and mowing processes and enter standby mode. For example, if the second detection element detects a dog in front of the lawnmower for an extended period during automatic movement, the controller will control the lawnmower to temporarily stop moving and mowing.
- the controller in automatic mode, while the ride-on lawnmower is automatically traveling along the planned path, if a user or obstacle is detected within a period shorter than a third preset time interval, the controller will control the ride-on lawnmower to avoid the user or obstacle and continue traveling automatically along the planned path.
- the second preset time interval is longer than the third preset time interval.
- the third preset time interval can be set according to actual needs, for example, it can be set to 2 seconds, 3 seconds, or a time shorter than the second preset time interval.
- the controller 5 in automatic mode, while the ride-on lawnmower is automatically traveling along the planned path, the controller 5 will acquire second detection data from the second detection element 6 in real time or intermittently regarding the presence of a user or obstacle in the direction of travel of the ride-on lawnmower.
- the controller can control the ride-on lawnmower to avoid the obstacle. By actively avoiding short-term obstacles, the flexibility and safety of the ride-on lawnmower are improved.
- control actions for the lawnmower in response to the abnormal situations described above can exist individually or in combination within the lawnmower; this application does not limit this. These control actions can ensure the safety of the lawnmower and nearby users, or improve the lawnmower's working efficiency.
- the controller 5 in manual mode, operates solely according to user instructions, and detecting obstacles does not alter the riding lawnmower's path or operating status. In manual mode, the controller 5 controls the riding lawnmower to perform at least one of the following operations: acquiring obstacle information detected by the second detection element 6, and acquiring the location information when an obstacle is detected and marking it on a map for subsequent path planning in automatic mode.
- the positioning sensor 1 and the second detection element 6 may only acquire detection data without processing it, or they may both acquire and process the detection data.
- the positioning sensor 1 and the second detection element 6 may only acquire detection data regarding whether there are obstacles around the riding lawnmower, or they may process the acquired detection data to generate detection data indicating whether there are obstacles or not around the riding lawnmower.
- the controller 5 records the detection results of obstacles around the automatic lawnmower obtained by the second detection element 6, or records the detection results of obstacles in front of the automatic lawnmower obtained by the positioning sensor 1, and updates the map based on the recorded detection results.
- the lawnmower when the lawnmower terminates its task in automatic mode, it can be controlled to continue moving after no obstacles are detected, ensuring flexible operation of the lawnmower.
- the lawnmower when the lawnmower terminates its task in automatic mode, it can also resume operation in response to a user command.
- exiting manual mode allows control to stop the automatic lawnmower's movement and mowing operations.
- the lawnmower is detected to have stopped moving, if a user is identified on the carrier and at least one user confirmation command is received, the lawnmower's movement and operation are controlled in response to input from the motion adjustment unit.
- the lawnmower is detected to have not stopped moving, if a user is identified on the carrier, the lawnmower's movement and operation are controlled in response to input from the motion adjustment unit.
- the user confirmation command is consistent with the commands described above, such as triggering a confirmation button or obtaining a password.
- the lawnmower after exiting manual mode, if a user is detected on the carrier, the lawnmower is controlled to enter automatic mode in response to a confirmation command to switch to automatic.
- the motion adjustment unit is disabled when exiting manual or automatic mode, thereby preventing the human-machine interface module from being accidentally touched by tree branches or users in non-automatic mode, which could cause the machine to make erroneous operations based on the result of the accidental touch, posing a safety risk to the user or living creatures in the environment.
- the riding lawnmower in manual mode, is controlled to move according to the driving direction or speed input by the motion adjustment unit 4.
- the riding lawnmower cannot be controlled to move according to the driving direction or speed input by the motion adjustment unit 4; that is, the motion adjustment unit malfunctions.
- the motion adjustment unit By controlling the motion adjustment unit to malfunction, it is prevented from being accidentally touched by tree branches or users, thereby preventing accidental operation based on the result of accidental touch and posing a safety risk to users or living things in the environment.
- the user In manual mode, the user inputs the driving direction or speed through the motion adjustment unit 4 to control the ride-on lawnmower to move and work according to the user's intention.
- the automatic lawnmower When exiting manual mode or in automatic mode, in response to the input from the motion adjustment unit, the automatic lawnmower maintains its driving direction and travels along the planned path. That is, the ride-on lawnmower cannot be controlled to move based on the driving direction or speed input from the motion adjustment unit 4.
- the motion adjustment unit 4 includes a joystick, etc., and the controller 5 will not perform any operation in response to user input via the joystick.
- the ride-on lawnmower may also include a speed controller for adjusting the riding speed. When the lawnmower exits manual mode or enters automatic mode, the controller 5 will not adjust the driving speed in response to user input.
- the speed controller can also be a joystick, used to control the lawnmower's direction and speed.
- the human-machine interface module may further include a user interface, which includes operation keys.
- the controller is further configured to disable the operation keys when exiting manual mode or in automatic mode.
- the operation keys do not include a stop button. That is, in automatic mode, in response to input of the operation keys, the automatic lawnmower is controlled to maintain its driving direction or speed.
- the automatic lawnmower includes a human-machine interface module (HMI) through which a user interacts with the automatic lawnmower.
- HMI human-machine interface module
- the controller is further configured to: after exiting manual mode or entering automatic mode, control the HMI to be in a retracted position; and after entering manual mode, control the HMI to be in a working position. By controlling the HMI to be in the retracted position, the user cannot operate the HMI after exiting manual mode or entering automatic mode.
- the user interface includes operation keys.
- a protective cover is provided on the lawnmower and is closable, positioned over the operation keys.
- the controller is further configured to: close the protective cover when exiting manual mode or in automatic mode; and open the protective cover in manual mode. By closing the protective cover on the operation keys, the user cannot operate the operation keys after exiting manual mode or entering automatic mode.
- the controller 5 controls the lawnmower to travel along the boundary of the work area based on received mapping instructions.
- a map of the work area is created based on location information collected by positioning sensors.
- the ride-on lawnmower may include a control panel with a mapping button for triggering the mapping mode. After the mapping button is triggered, the controller 5 receives the mapping instruction.
- the app used to control the ride-on lawnmower also has a mapping button; when the user triggers this button, the app sends a mapping instruction to the ride-on lawnmower.
- the maximum travel speed of the automatic lawnmower in mapping mode is controlled to be less than or equal to its travel speed in working mode. Controlling the travel speed in mapping mode to be less than or equal to its maximum travel speed during mowing ensures that the ride-on lawnmower can travel more accurately along the boundaries of the work area, improving the accuracy of the map of the work area and the safety of the ride-on lawnmower.
- the maximum travel speed of the ride-on lawnmower during mowing can be set according to actual needs, for example, it can be set to 1 m/s.
- the controller 5 when a mapping instruction is received, acquires the first detection data of the first detection element 2. If the controller determines that there is a user on the ride-on automatic lawnmower based on the first detection data, the controller 5 controls the ride-on lawnmower to travel along the boundary according to the user's instruction. If the controller determines that there is no user on the ride-on lawnmower based on the first detection data, the controller 5 controls it to stop traveling along the boundary of the work area and stops building the map of the work area.
- controller 5 can send a corresponding reminder message to the APP, allowing the APP to display two operation options—continue mapping and end mapping—through a pop-up window. This allows users to conveniently choose the appropriate operation option based on their needs.
- controller 5 can end mapping.
- controller 5 can also send a prompt message to the associated terminal, indicating whether to end mapping and/or continue mapping, and process the feedback message sent by the associated terminal accordingly.
- the associated terminal can be a terminal that is bound to or has established a communication connection with the ride-on lawnmower.
- the maximum speed of the lawnmower in manual mode is greater than the maximum speed in automatic mode. Setting a lower speed in automatic mode prevents the lawnmower from colliding with pedestrians or causing other safety hazards, thus improving work efficiency while ensuring the safety of the ride-on lawnmower. After mowing the lawn for one customer, the user needs to ride the lawnmower to another customer's location. Setting a higher speed in manual mode increases the speed of travel to the next customer, shortening the transfer time. For example, setting the maximum speed in manual mode to 5 m/s and the maximum speed in automatic mode to 2 m/s.
- the lawnmower's travel speed during relocation can be set to be higher than the maximum travel speed during normal mowing operations. This ensures safety during the normal movement of the lawnmower under manual control.
- the maximum travel speed during normal mowing operations can be set to 3 m/s.
- the controller 5 controls the riding lawnmower to travel at a speed less than or equal to its maximum forward speed when moving backward.
- the backward speed is less than or equal to the maximum forward speed; in automatic mode, the backward speed is less than or equal to the maximum forward speed. Since control of the riding lawnmower may be less flexible when moving backward compared to when it is in operation, the controller 5 controls the lawnmower to travel at a speed less than or equal to its maximum forward speed when moving backward.
- the lawnmower's memory stores maximum travel speeds associated with various operating states. By identifying the lawnmower's current operating state, the system controls the lawnmower to switch to different maximum travel speeds. The lawnmower can automatically switch to the corresponding maximum travel speed based on different operating states. For example, if the lawnmower is detected moving between locations, the maximum travel speed is switched to the speed for that scenario; if the lawnmower is detected moving forward in automatic mode, the maximum travel speed is switched to the forward speed in automatic mode; if the lawnmower is detected moving backward in automatic mode, the maximum travel speed is switched to the backward speed in automatic mode.
- the lawnmower's memory stores the maximum travel speed associated with each working position. By identifying the lawnmower's working position, the system controls the lawnmower to switch to different maximum travel speed limits. The lawnmower can automatically switch to the corresponding maximum travel speed based on different working positions. For example, when the lawnmower is detected to be in a transitional location, the maximum travel speed is switched to the speed for that transitional scenario; when the lawnmower is detected to be in a working area, the maximum travel speed is switched to the speed in automatic or manual mode based on the working status.
- the ride-on lawnmower is equipped with a standby mode.
- the controller 5 In standby mode, the controller 5 is in a state of task process interruption, termination, or no task instruction received.
- the controller 5 is configured to adjust the cutting unit 3 to its highest position in the vertical direction.
- the controller 5 adjusts the cutting unit 3 to its highest vertical position to protect the cutting unit 3 and prevent accidental contact by the user. It should be noted that in standby mode, the controller 5 can receive commands to adjust the height of the cutting unit 3, but will not adjust the height of the cutting unit 3 itself.
- the controller 5 when the riding lawnmower switches from standby mode to automatic mode, the controller 5 is configured to adjust the cutting section to the height required by the height adjustment command received in standby mode.
- the height adjustment command for the cutting head can be input by the user through the control panel of the ride-on lawnmower, or it can be input by the user through an app and sent from the app to the ride-on lawnmower. Since the ride-on lawnmower may not detect obstacles in standby mode, to prevent damage to the cutting head from obstacles, the controller 5 only adjusts the cutting head to the height required by the height adjustment command received in standby mode when the ride-on lawnmower switches from standby mode to automatic mode. This improves the safety of the ride-on lawnmower.
- the cutting unit 3 includes at least two cutting elements configured to perform mowing operations according to a received cutting command; the cutting unit 3 sequentially activates the at least two cutting elements according to the received cutting command.
- the at least two cutting elements are activated sequentially when mowing begins to prevent excessive current and overcurrent problems caused by simultaneous activation.
- the time interval between adjacent activations of the cutting elements can be set according to actual needs, such as 2 seconds.
- the ride-on lawnmower is controlled to enter manual mode only upon detecting the presence of a user on it.
- the ride-on lawnmower By controlling the ride-on lawnmower to enter manual mode only after detecting the presence of a user, the safety risks associated with operating the machine in manual mode if the user is not in the correct driving position are avoided. This achieves efficient cutting while ensuring user safety, automatically switching the operating mode of the lawnmower and improving the user experience.
- an employer When an employer receives a job to maintain a client's garden, they first create a boundary map of the garden.
- map creation the automatic lawnmower is in manual mode. Specifically, the user sits down with the backrest extended. A dialog box appears on the lawnmower's control panel asking the employer to confirm entry into manual mode; the employer clicks "confirm.” The user then clicks the "joystick” button and enters a password. If the password is correct, the employer is allowed to use the joystick to control the lawnmower to travel along the boundary. Position information is collected via positioning sensors to create the boundary map. After the lawnmower completes one lap around the boundary, the user either generates the map themselves or generates and saves it in the cloud.
- the employer will then proceed to maintain the client's garden according to the established rules.
- the control panel displays a prompt to "Download map in the app.”
- the app automatically searches for nearby maps; the employer selects the map of the client's garden and clicks "Download” to download the map to the lawnmower.
- the screen will display "Success”. Press the start and OK buttons on the automatic lawnmower's control panel and move away from the mower. When the mower no longer recognizes the user, the controller will automatically start working according to the map.
- the automatic lawnmower will stop immediately.
- press the start and OK buttons the mower will then continue automatically.
- the automatic lawnmower will return to its starting point and wait, allowing the employer to drive it to a nearby customer's home.

- Step S402 At least in response to the detection of a user on the automatic lawnmower, control the automatic lawnmower to enter manual mode; in manual mode, the automatic lawnmower travels along the path or direction input by the user.
- the user When it is determined from the first detection data that there is a user on the automatic lawnmower, it means that the user wants to manually operate the automatic lawnmower. At least according to the signal indicating that there is a user on the automatic lawnmower, the user enters the manual mode so that the automatic lawnmower can travel in the direction or speed input by the user.
- the automatic lawnmower is controlled to enter automatic mode; in automatic mode, the automatic lawnmower is controlled to automatically travel along the planned path based at least on the location information.
- control method for the automatic lawnmower controls the ride-on lawnmower to enter manual mode only when a user is detected on the ride-on lawnmower. This avoids the safety risks that may arise if the user operates the machine in a position other than the correct driving position in manual mode.

- the system in response to detecting that no user is present on the automatic lawnmower within a fifth preset time period, the system is controlled to exit manual mode.
- This fifth preset time period is longer than a fourth preset time period. If no user is detected for an extended period, it indicates that the user has most likely left the lawnmower, and manual mode needs to be exited.
- operations such as recording obstacles and updating the map which are performed in manual mode as described above, can be combined with operations such as controlling the automatic lawnmower to stop moving and mowing after exiting manual mode.
- the speed of the lawnmower in different working states and the height adjustment of the cutting section described above can be combined. Due to space limitations, these details will not be elaborated upon here.
- the automatic lawnmower provided in this application disables the motion adjustment unit after exiting manual mode or entering automatic mode, thereby preventing the human-machine control module from being accidentally touched by tree branches or users in non-automatic mode, which could lead to the machine making erroneous operations based on the result of the accidental touch and pose a safety risk to users or living things in the environment.
- the robot's main body is the chassis, and the seat supports the user.
- Sensors for acquiring vertical acceleration and pressure data are located at the seat.
- the vertical acceleration sensor acquires the seat's vertical acceleration
- the pressure sensor acquires the seat's pressure.
- the robot is confirmed to be in riding mode, and then it is determined whether it is in a bumpy ride.
- the time the user has been off the seat exceeds the normal time range for bouncing, then it is determined that the user has completely left the seat, and riding mode is exited.
- a time range i.e., a first preset duration
- the anomaly detection sensor may include a pressure sensor for detecting pressure on the carrier and an acceleration sensor for detecting the acceleration component of the carrier at least in the vertical direction.
- the controller is configured to determine the time period during which the user left the carrier based on the pressure detected by the pressure sensor; the controller is configured to determine whether the machine user is experiencing a bumpy condition based on the vertical acceleration component of the carrier detected by the acceleration sensor.
- the acceleration sensor is an IMU sensor used to acquire the vertical acceleration of the carrier.
- the detection sensor may also be a sensor that simultaneously detects pressure on the carrier and vertical acceleration, or a camera, ultrasonic sensor, etc., to identify the environment surrounding the machine user; no specific limitation is made here.
- the carrier is generally described using a driver's seat as an example.
- the user's state on the support can be represented by the numerical value or phase of the pressure sensor. Based on the temporal pattern of the pressure sensor results, the time period during which the user left the support can be determined. Furthermore, the vertical acceleration of the support has different ranges under bumpy and non-bumpy conditions. An acceleration sensor detects the vertical acceleration of the support seat in real time; the portion exceeding the vertical acceleration range under non-bumpy conditions indicates a bumpy condition. The pressure and acceleration sensors can quickly and in real time obtain changes in pressure and vertical acceleration over time.
- the following steps may also be included:
- the seat is in a bumpy state
- the user has two possible states: the user is sitting on the seat or the user is off the seat.
- the user may be off the seat due to a brief bounce caused by the bump; the other possibility is that the user has dismounted. Therefore, it is necessary to confirm that the user is off the seat in riding mode (i.e., manual mode mentioned above) and to determine whether the machine user is in a bumpy state.
- a fourth preset time period is used to determine whether to dismount.
- the fourth preset time period is determined based on the brief duration of the user's airborne state during the bump, and it can be greater than or equal to the normal airborne state.
- the time the user spends off the seat exceeds the fourth preset time period i.e., exceeds the normal airborne time range during the bump, then it is determined that the user has dismounted, and the machine user exits riding mode. If the user returns to the seat within the fourth preset time period, it indicates that the user is in a riding state, and the detected departure from the seat is only a brief airborne state, so there is no need to exit riding mode.
- the system determines whether the user is exiting the ride or experiencing a brief period of being lifted off the ground by considering the duration of the user's absence from the seat. It then switches between riding and non-riding modes to avoid misjudgment due to brief periods of being lifted off the ground.
- the user's departure from the seat is determined by detecting the pressure on the seat.
- the pressure on the seat changes dynamically.
- the pressure state on the seat can be divided into three types: the user is fully seated, the user is completely off the seat, and the user is neither fully seated nor completely off the seat.
- detecting pressure on the seat includes detecting pressure on the seat using a pressure sensor.
- the pressure sensor has an information acquisition port, referred to as an I/O port.
- the I/O port is configured in input mode, with input values of 0 and 1.
- T_SEAT_P1 and T_SEAT_P2 are two pressure sensors, and IO_SEAT_P1 and IO_SEAT_P2 are two signal acquisition I/O ports.
- T_SEAT_P1 is the first pressure sensor installed in the grounding circuit, denoted as P1
- T_SEAT_P2 is the second pressure sensor installed in the power supply circuit, denoted as P2.
- the input value of P1 When the user is fully seated, the input value of P1 is 1, and the input value of P2 is 0; when the user is fully away from the seat, the input value of P1 is 0, and the input value of P2 is 1; when the user is neither fully seated nor fully away from the seat, the input values of both P1 and P2 are 1, or both P1 and P2 are 0.
- the user's state in the seat has four representations: 10, 01, 11, and 00. Therefore, the duration during which the user is fully away from the seat is identified, which is the duration during which the input value of P1 is 0 and the input value of P2 is 1.
- the method for detecting pressure includes at least one of the following: detecting pressure by detecting the strain of a strain gauge; detecting pressure by observing deformation using a high-speed camera; or calculating pressure by measuring displacement through contact with a mechanical device on the seat.
- the specific method by which the user of the detection machine detects the seat pressure is not limited.
- detecting pressure on the seat includes at least one of the following: detecting the seat's vertical acceleration, using image recognition, detecting angular motion using a gyroscope, or detecting the duration of the user's absence from the seat.
- the specific method for detecting whether the user is in a bumpy state is not limited; it can be selected according to actual needs. Specifically, the absolute value of the seat's vertical acceleration is greater in a bumpy state than in a stable state; therefore, detecting vertical acceleration can determine whether the seat is in a bumpy state.
- Image recognition of road surface smoothness or the user's driving state can also determine whether the user is in a bumpy state. In a bumpy state, the angle between the user and the road surface also changes; therefore, angular motion can be detected using a gyroscope.
- the system determines whether the user is experiencing a bumpy ride by detecting the vertical acceleration of the seat.
- acceleration fluctuates vertically.
- the acceleration data is divided into two parts: data A (greater than *g*) and data B (less than *g*).
- data A greater than *g*
- data B less than *g*
- a range of data far from *g* is removed from both A and B, resulting in bumpy data.
- bump endpoints 'a' for A and 'b' for B.
- Data with vertical acceleration magnitudes between [- ⁇ , b] and [a, + ⁇ ] represent the bumpy range data, thus accurately determining the bumpy range.
- data within 10% of the smooth acceleration g are removed, specifically data in the range [g-0.1, g+0.1].
- Data far from the smooth acceleration are also removed. For example, if a set of acceleration data falls within the range [g-1, g+2], then data in the ranges [g+1.8, g+2] and [g-0.9, g-1] need to be removed. In other words, if acceleration data falls within the range [g-1, g+2], then data in the ranges [g-0.1, g+0.1], [g+1.8, g+2], and [g-0.9, g-1] need to be removed. Then, the median of the remaining data for ranges A and B is calculated to obtain a and b, thus yielding the turbulence range data.
- two pressure sensors detect the state between the user and the seat, detecting four pressure states: 10, 00, 11, and 01. These represent three seat states: fully seated (10), fully alighted (01), and neither fully seated nor fully alighted (11 and 00).
- the user's position on the seat affects the vertical acceleration detection results, so the data detected in the three seat states needs to be divided into three data ranges to calculate three bump intervals.
- the fully alighted state may include data from the non-riding state
- the bump intervals for either the fully seated or partially alighted state are selected to define the bump state in riding mode.
- the machine user is controlled to exit the riding mode. This includes: firstly, obtaining the real-time acceleration of the user when the user completely leaves the seat; defining the portion of the real-time acceleration that exceeds the preset range of vertical acceleration as the airborne acceleration range; and if the user's actual acceleration remains within the airborne acceleration range for more than the fifth preset time period, then confirming that the user has exited the riding mode, and controlling the machine user to exit the riding mode.
- data from the completely departed state (01) is taken, including data A with a velocity greater than the smooth acceleration g and data B with a velocity less than the smooth acceleration g.
- the takeoff acceleration range is divided into the takeoff acceleration range C (greater than g) and the takeoff acceleration range D (less than g).
- the median is selected as the confirmation value in the takeoff acceleration range: among several values in the takeoff acceleration range C, the median c is selected as the takeoff endpoint; among several values in the takeoff acceleration range D, the median d is selected as the takeoff endpoint.
- the smooth acceleration is g.
- the range 10% away from g in data A is defined as the takeoff acceleration range C; the range 10% away from g in data B is defined as the takeoff acceleration range D. If a set of acceleration data falls within the interval [g-1, g+2], then the takeoff acceleration range C is [g+1.8, g+2], and the takeoff acceleration range D is [g-0.9, g-1].
- the actual acceleration of the machine user remains within the range of [g+1.8, g+2] or [g-0.9, g-1] for a duration exceeding a first preset time, it is confirmed that the user has exited the riding mode, and the machine user is controlled to exit the riding mode.
- the system controls the user to exit the riding mode based on the duration of time the user is away from the seat.
- the user In a non-bumpy environment, the user has two possible states: a brief change in riding posture or no longer needing to ride. The user's state is determined by the time they leave the seat. If the time is long enough, it is determined that riding is no longer needed, and the user exits riding mode. In a non-bumpy environment, there is no risk of the user being thrown off the seat; the user's riding state is determined directly by the length of time they are off the seat, ensuring timely switching between riding and non-riding modes.
- the automatic lawnmower is not malfunctioning based on information detected by the anomaly detection sensor.
- manual mode in response to the absence of a user on the automatic lawnmower within a fifth preset time period and the absence of an anomaly, the automatic lawnmower is controlled to exit manual mode.
- the fifth preset time period is longer than the fourth preset time period. Specifically, in a non-bumpy state, the user will not be passively lifted off the ground; the riding action is generally actively changed. Therefore, the fifth preset time period is longer than the fourth preset time period, allowing for a determination of whether the user temporarily leaves the seat to change their riding action or decides not to ride anymore.
- the machine user it is first confirmed whether the machine user is in riding mode, then it is determined whether the user has left the seat while in riding mode, and whether the machine user is in an abnormal state. If the machine user is confirmed to be in an abnormal state, the exit from riding mode is confirmed only after the user has been away from the seat for a preset time period. In an abnormal state, the user may bounce up, causing a brief absence from the seat. By determining the time period of the user's absence, it is possible to avoid misinterpreting a brief bounce as an exit from riding mode. Accurately identifying the user's riding state ensures the stability of operating the machine user even in abnormal states.
- the human-machine interface module includes at least two position states: a folded state and an unfolded state.
- the automatic lawnmower In response to a first detection element detecting that the carrier or the human-machine interface module is in the folded state, the automatic lawnmower is controlled to enter automatic mode.

本实施方式中以自动割草机1000为骑乘式割草机为例进行说明。结合图1至图2所示,骑乘式割草机100又称草坪机,用于供用户骑乘并在地面上行走执行植被的切割维护工作。下文的一些位置处,以骑乘式割草机为例进行表述,但含义与自动割草机一致,即,方案也可以应用于自动割草机。骑乘式割草机100可通过多种方式提供能源,示例性的,骑乘式割草机100通过电池提供行走以及工作的能量。
骑乘式割草机100包括机身9。设置于机身9上,用于承载用户的承载件253,例如图1至图2中所示意的供用户乘坐的座椅25或站立的站板23(图中未示出)。安装于机身9上,用于执行切割工作的切割部3。设置于机身9下方的移动组件7,带动机身9在地面G上行走工作。
如图1至图3所示,骑乘式割草机100还可以包括:定位传感器1,安装于机身,被配置为采集骑乘式割草机行驶过程中的位置信息。可以是视觉传感器,卫星定位传感器,超声或雷达等,也可以是这些传感器的组合。
如图1至图3,以及,如图10至图11所示,骑乘式割草机100还可以包括人机操作模块8,与机身200相连。人机操作模块8可以包括运动调整部4或用户界面12。
在一些具体的实施方式中,如图1至3所示,人机操作模块8位于操作台13上,操作台13沿与机身行进方向相同的方向纵长延伸,整体呈长方体,其内部形成有收容空间,用于收纳控制骑乘式割草机100所需的机械及电子零件。示例性的,操作台13上可以设置有用户界面12以及运动调整部4,用于供用户操作,以控制骑乘式割草机100的行走工作。
本公开一些具体实施方式中,运动调整部4用于供用户输入行驶方向或行驶速度。运动调整部4包括摇杆。摇杆包括操作杆211或操控扶手24。当用户通过摇杆输入行驶方向时,通过与操作杆211或操控扶手24电连接的操控控制器(图中未示出)控制行驶方向;当用户通过摇杆输入行驶速度时,通过与操作杆211或操控扶手24电连接的操控控制器(图中未示出)控制行驶速度。以摇杆是操作杆211为例进行说明。操作杆211根据用户输入向不同方向移动,不同方向至少包括从初始位置向前后左右方向的移动。处于初始位置时,骑乘式割草机100保持当前的移动状态,当操作杆211产生位置移动时,方向控制器检测操作杆211的移动方向,并控制移动组件7改向与操作杆211位移方向相同的方向行走。本领域技术用户员能够想到的是,运动调整部4也可以具有其他多种形式,例如方向盘或者触摸板,通过转动方向盘或者在触摸板上画出行进方向的形式控制移动组件7行走方向的改变,在此不一一列举。
本公开一些具体实施方式中,用户界面12用于供用户输入行驶方向,或,行驶速度,或,工作区域,或,切割参数等信息。用户界面可以是设置有触摸按键的显示屏,也可以是物理按键形式。操作台13或用户界面12包括控制骑乘式割草机100工作的操作键10,用户通过操作键10控制骑乘式割草机100开机/关机、启动/关闭切割部3、调整切割部3的工作模式等。操作键10可以是上述物理按键形式,也可以是触摸按键形式。
本公开一些具体实施方式中,操作台13或用户界面12上设置有停机按键213,停机按键213用于在紧急情况下,供用户触发以立即停止骑乘式割草机100的行驶和/或切割工作。示例性的,停机按键213为按钮形式,且被配置为按压面积较大,以利于用户识别及有效按压,避免误操作。可选地,停机按键与运动调整部4相邻的设置,以使得用户正在通过运动调整部4控制骑乘式割草机时一旦发现需要紧急制动,可以获得将手从运动调整部4移动至停机按键213的最小移动距离,更加的便于操作及安全。
本公开一些具体实施方式中,操作台或用户界面12上设置有显示装置215,显示装置215用于向用户显示骑乘式割草机100的实时状态,包括骑乘式割草机100的剩余电量,工作状况等信息。可选择的,显示装置215具有触摸输入功能,用户可通过显示装置215直接向骑乘式割草机100输入控制指令,影响骑乘式割草机100的行走工作。
考虑到当骑乘割草机兼具自动模式和手动模式时,在手动模式下,如果用户未处于正确的驾驶位置就去操控机器会存在安全风险,本申请实施方式中提出了当无法在自动割草机上识别到用户,则不允许自动割草机进入手动模式的技术方案。具体的细节如下。
参阅图3以及图4,为本申请实施方式中提供的一种骑乘式割草机,骑乘式割草机在地图限定的工作区域中行驶和\或割草,所述骑乘式割草机包括:
机身9;
定位传感器1,安装于机身,被配置为采集骑乘式割草机行驶过程中的位置信息;
第一检测元件2,安装于机身,被配置为获取表征骑乘式割草机上是否存在用户的第一检测数据;
切割部3,安装于机身,被配置为根据所接收到的切割指令执行割草操作;
运动调整部4,安装于机身,被配置为供用户输入行驶方向以及行驶速度;
控制器5,与第一检测元件2信号相连,被配置为接收第一检测数据;根据第一检测数据识别骑乘式割草机上是否存在用户。
其中,骑乘式割草机包括两种工作模式:手动模式、自动模式。在手动模式下,骑乘式割草机按照用户输入的行驶方向或行驶速度行驶。在自动模式下,至少基于位置信息控制骑乘式割草机自动沿规划的路径行驶。规划的路径是预先在地图上设置的路径,可以是根据用户驾驶骑乘式割草机在工作区域上的行驶数据所生成的,也可以是割草机按照现有的路径规划算法通过计算得到的,在此不作具体限定。
在一些实施方式中,至少响应于识别到骑乘式割草机上存在用户,控制骑乘式割草机进入手动模式。通过至少在识别到骑乘式割草机上存在用户,才控制骑乘式割草机进入手动模式,避免手动模式下,如果用户未处于正确的驾驶位置就去操控机器时所带来的安全风险,实现在高效切割且保证使用者安全的同时,自动切换自动割草机的工作模式,提升了用户使用体验。
其中,当处于自动模式时,如果根据第一检测数据确定骑乘式割草机上存在用户,则控制其退出自动模式,进入待机模式,或,进入手动模式。
其中,定位传感器1、第一检测元件2和控制器5可设置于机身9上。定位传感器1可实时采集骑乘式割草机行驶过程中的位置信息,并传输给控制器5。第一检测元件2用于实时或周期性获取第一检测数据,具体可以为压力传感器、图像传感器等。控制器5在接收到来自第一检测元件2的第一检测数据后,根据第一检测数据确定骑乘式割草机上是否存在用户。当确定骑乘式割草机上存在用户时,至少响应于识别到骑乘式割草机上存在用户的信号,控制器控制骑乘式割草机进入手动模式。
在一些实施方式中,在手动模式下,在接收到用户确认指令之后,响应于用户通过运动调整部输入的行驶方向或行驶速度,控制器控制骑乘式割草机移动。或者,也可以是至少接收到两个用户确认指令,本申请对此不作限定。在另一些实施方式中,无需接收到用户确认指令。即,在手动模式下,响应于用户通过运动调整部输入的行驶方向或行驶速度,控制器控制骑乘式割草机移动。可以根据用户对于骑乘式割草机的安全需求自行选择使用上述两种方式中的任一种。
用户指令可以是密码确认指令、确认指令、对摇杆的解锁指令、对预设按键如确认按键的触发指令等。
其中,用户手动输入行驶方向或行驶速度的方式可包括:用户通过运动调整部4输入,用户通过APP对骑乘式割草机进行遥控,或者,用户通过语音方式输入等。控制器5可包括第一检测元件2中的处理器等能够处理数据的元器件。
在一些实施方式中,控制器5还被配置为至少根据第一检测数据确定骑乘式割草机上不存在用户,控制骑乘式割草机进入自动模式,退出手动模式,或,进入待机模式。
具体地,至少响应于识别到骑乘式割草机上不存在用户,控制骑乘式割草机进入自动模式。当骑乘式割草机上不存在用户时,则允许机器进入自动模式,以在保证安全的同时提高机器的智能性;当骑乘式割草机上存在用户时,不能进入自动模式,避免用户在机器自动移动时从机器摔落或发生其他危险。
在一些实施方式中,至少响应于识别到所述自动割草机上存在用户,控制所述自动割草机进入手动模式;至少响应于识别到所述自动割草机上不存在用户,控制所述自动割草机进入所述自动模式。在一种应用场景下,花园雇佣者携带吹吸机、打草头以及本申请中的骑乘式割草机等花园工具去客户家花园工作,由于骑乘式割草机为自动模式和手动模式可选的机器,因此,花园雇佣者可以控制骑乘式割草机处于无人骑乘的自动模式,这样他就可以在骑乘式割草机工作的过程中使用吹吸机或打草头进行其他的花园护理工作。对于狭窄区域或者阴影区域等骑乘式割草机无法在自动模式下工作的区域,可以控制骑乘式割草机处于有人骑乘的手动模式,从而节省用户人力成本,并提高处理效率。
可以理解,为了避免出现骑乘式割草机因自动行驶而碰撞到周围的用户等情况,在控制骑乘式割草机进入自动模式后,控制器5可在只有接收到用户指令的情况下,才可控制骑乘式割草机自动沿规划的路径行驶,以执行工作任务。其中,用户指令可以是用户通过APP输入并由APP发送给控制器5的,也可以是用户直接向骑乘式割草机输入的。如此,提高了骑乘式割草机的使用安全性,进一步提升了用户使用体验。
在一些实施方式中,可以响应于如下指令控制骑乘式割草机自动沿规划的路径行驶,也可以通过如下指令的组合控制骑乘式割草机自动沿规划的路径行驶。当然,分别均可以与上面所描述的其他实施方式结合。
在一些实施方式中,在自动模式下,响应于接收到至少两个不同的用户指令,控制骑乘式割草机自动沿规划的路径行驶。例如:密码确认指令、对摇杆的解锁指令等用户指令。如此,提高了骑乘式割草机的使用安全,进一步提升了用户使用体验。
在一些实施方式中,骑乘式割草机还包括用户界面,用户界面上设置有至少两个操作键。在自动模式下,响应于接收到来自至少两个操作键的确认指令,控制骑乘式割草机沿自动规划的路径行驶。其中,至少两个操作键可以包括开始按键和确认按键等。
在一些实施方式中,骑乘式自动割草机还可以包括:第二检测元件6,被配置为至少获取骑乘式割草机的移动方向上是否存在用户或障碍物的第二检测数据,并发送至控制器5。第二检测元件6可以为摄像头或超声、雷达传感器等能够识别用户或障碍物的传感器。第二检测元件6可以设置在骑乘式割草机机身前侧或者也可以设置在机身最高位置处。
根据用户对安全的需要,在控制割草机前进的过程中,第二检测元件6用于实时获取骑乘式割草机的前方以及左右两侧区域中的数据,并根据该数据判断是否存在用户或障碍物,该区域为传感器可覆盖的范围。其中,当割草机在前进时,所获取的前方区域范围宽度大于左右两侧区域的宽度。可以理解的是,前进过程中,会影响割草机移动的情况主要发生的前方,而非左右两侧,因此,前方需要设置更大的安全宽度。如图12所示,宽度P小于宽度Q。
替代的,在另一些实施方式中,在控制割草机前进的过程中,第二检测元件6用于实时获取骑乘式割草机的前方、后方以及左右两侧区域中的数据,以判断是否存在用户或障碍物。
在一些实施方式中,骑乘式自动割草机还包括:第二检测元件6,设置在割草机四周,被配置为获取骑乘式割草机周围是否存在用户或障碍物的第二检测数据,并发送至控制器5。第二检测元件6可以设置在骑乘式割草机机身周围一圈或者也可以设置在机身最高位置处。需要说明的是,由于第二检测元件6可能存在检测盲区,因此,第二检测元件6可以设置有多个,比如4个或以上等。
在一些实施方式中,在自动模式下,在根据第二检测数据识别到不存在用户或障碍物的情况下,控制所述自动割草机自动沿规划的路径行驶。
在一些实施方式中,在自动模式下,根据第二检测数据识别到存在用户或障碍物,且,在第一预设时间段后识别到不存在用户或障碍物,则至少响应于在第一预设时间段内从识别到存在用户或障碍物至不存在用户或障碍物的检测数据变化,控制自动割草机自动沿规划的路径行驶。如此,以保证用户安全。其中,第一预设时间段可以根据实际情况需要进行设置,比如,可以设置为20s、30s等。
值得说明的是,自动割草机可以响应于多条指令来控制骑乘式割草机自动沿规划的路径行驶。例如:在自动模式下,在接收到用户指令之后,在根据第二检测数据识别到不存在用户或障碍物的情况下,控制所述自动割草机自动沿规划的路径行驶。
或者,也可以是在自动模式下,在接收到用户指令之后,根据第二检测数据识别到存在用户或障碍物,且,在第一预设时间段后识别到不存在用户或障碍物,则至少响应于在第一预设时间段内从识别到存在用户或障碍物至不存在用户或障碍物的检测数据变化,控制自动割草机自动沿规划的路径行驶。通过多条指令来控制骑乘式割草机自动沿规划的路径行驶,保证割草机以及附近用户的安全。在根据第一检测数据确定骑乘式割草机上无用户的情况下,若根据第二检测数据识别到骑乘式割草机从存在用户至不存在用户的检测数据变化,说明骑乘式割草机上的用户已经远离割草机,避免出现用户站在割草机上操作割草机的情况。
示例性地,假设用户希望骑乘式割草机能够自动执行割草操作,则用户可以先站在骑乘式割草机的驾驶位置,并打开控制面板的电源开关以启动骑乘式割草机,然后离开驾驶位置。控制器5根据第一检测元件2的第一检测数据确定骑乘式割草机上无用户,根据第二检测元件6一开始识别到存在用户或障碍物,且,在30s后第二检测元件6识别到不存在用户或障碍物,控制骑乘式割草机自动沿规划的路径行驶。
另外,若根据第二检测数据一直识别到至少自动割草机移动方向上存在用户,则控制自动割草机发出语音或向用户端app发出通知消息以提醒用户离开。例如:在根据第一检测数据识别到割草机上不存在用户,根据第二检测数据识别到割草机所规划路径方向上存在用户,则控制自动割草机发出语音或向用户端app发出通知消息以提醒用户离开,以便于快速启动割草机。
在一些实施方式中,可以通过如下方式确定自动割草机上是否存在用户,也可以通过如下方式的组合确定自动割草机上是否存在用户。当然,分别均可以与上面所描述的其他实施方式结合。
在一些实施方式中,骑乘式自动割草机上设置有用于承载用户的承载件。当根据第一检测数据识别到承载件上存在用户时,确定割草机上存在用户;当所述第一检测数据识别到承载件上不存在用户时,确定自动割草机上不存在用户,以保证割草机以及附近用户的安全,或,提高割草机工作效率。
第一检测元件2可以设置于承载件上。也可以设置在其他能识别到承载件上是否存在用户的位置。
第一检测元件2可以具体包括压力传感器、红外传感器、霍尔传感器、视觉传感器等电子器件或者结构开关。承载件可以包括供用户乘坐的驾驶座椅或供用户站立的站板等。此外,第一检测元件2还可以通过检测人机操作模块(也可以是用户界面或摇杆)是否被触发,以便于用户确认承载件上是否存在用户,以在至少根据第一检测元件2检测到承载件上无用户时,控制骑乘式割草机进入自动模式。当割草机处于自动模式时,响应于根据第一检测数据识别到承载件上存在用户,控制自动割草机退出自动模式。如此,能够实现准确且快速判定骑乘式割草机上是否存在用户。
在一些实施方式中,承载件至少包括两种位置状态:收折状态以及展开状态。第一检测元件2可以为霍尔传感器。控制器被配置为:当根据第一检测数据确定承载件处于展开状态时,确定承载件上存在用户。至少响应于识别到自动割草机上存在用户,控制自动割草机进入手动模式。当根据第一检测数据确定承载件处于收折状态时,确定承载件上不存在用户。至少响应于识别到自动割草机上不存在用户,控制自动割草机进入自动模式。
在一些实施方式中,如图8以及图9所示,驾驶座椅包括:椅面22和靠背21,控制器被配置为:响应于识别到椅面和靠背从展开至收折的位置状态变化,控制自动割草机退出手动模式,或,进入待机模式;响应于识别到椅面和靠背从收折至展开的位置状态变化,控制自动割草机退出自动模式,或,进入待机模式。其中,图8中驾驶座椅处于收折状态,图9中驾驶座椅处于展开状态。
在一些实施方式中,如图10以及图11所示,承载件包括:站板23,控制器被配置为:响应于识别到站板从展开至收折的位置状态变化,控制自动割草机退出手动模式;响应于识别到椅面和靠背从收折至展开的位置状态变化,控制自动割草机退出自动模式。其中,图10中站板处于收折状态,图11中站板处于展开状态。
在一些实施方式中,第一检测元件2包括:压力检测传感器,设置于承载件上,压力检测传感器被配置为获取承载件上的压力值,第一检测数据为承载件所承受的压力。当根据第一检测数据确定压力大于等于预设压力阈值时,确定承载件上存在用户;当根据第一检测数据确定压力小于预设压力阈值时,确定承载件上不存在用户。
其中,压力检测传感器可以为传感器或开关等,比如可输出0或1的信号,1可表示存在用户,而0可表示无用户。以承载件是座椅为例,由于用户坐在座椅上时,座椅上的压力值将发生变化,因此,控制器5在接收到压力检测传感器所获取到的驾驶座椅上的压力值时,判断压力值是否大于预设压力阈值,若压力值大于预设压力阈值时,则确定驾驶座椅上存在用户;若压力值小于或等于预设压力阈值时,则确定驾驶座椅上无用户,或者继续检测驾驶座椅上是否存在用户。如此,通过检测驾驶座椅上的压力值判断骑乘式割草机上是否存在用户,能够实现准确且快速判定骑乘式割草机上是否存在用户。
在一些实施方式中,人机操作模块至少包括两种位置状态:收折状态以及展开状态。至少响应于根据位置状态信息确定承载件或人机操作模块处于收折状态,控制自动割草机进入自动模式;在自动模式下,响应于接收到用户指令,控制自动割草机自动沿规划的路径行驶。在自动模式下,通过控制这些模块收缩,减小机器在空间中的占用体积,从而提升其在特殊场景的通过性以及越障能力,特殊场景例如:狭窄空间以及由低矮树枝的场景,使得其作业场景更多元化。
在一些实施方式中,响应于检测数据检测到承载件或人机操作模块处于展开的状态,控制自动割草机退出自动模式,或,进入手动模式。
进一步的,在一些实施方式中,承载件或人机操作模块处于展开状态时,自动割草机具有第一尺寸;承载件或人机操作模块处于收折状态时,自动割草机具有第二尺寸,第一尺寸大于第二尺寸,第一尺寸和第二尺寸为自动割草机在空间中的任意相同方向的尺寸。
值得说明的是,自动割草机上可以只安装有上面任意一种第一检测元件,也可以同时安装有多种第一检测元件。例如:同时安装有检测压力的压力传感器(此时,压力传感器作为第三检测元件)和检测承载件位置状态的霍尔传感器(此时,霍尔传感器作为第二检测元件)。此时,响应于确定承载件处于展开状态,且,压力大于预设压力阈值,控制自动割草机进入手动模式;响应于确定承载件处于收折状态,且,压力小于预设压力阈值,控制自动割草机进入自动模式。通过多个传感器确定割草机上是否存在用户,保证割草机以及附近用户的安全。
在一些实施方式中,骑乘式割草机上的定位传感器1可以是视觉等能辅助获取前方环境信息的器件,根据定位传感器识别的前方环境信息,确定前方是否存在障碍物。
在一些实施方式中,当自动割草机处于手动模式或自动模式时会遇到异常情况,针对异常情况,割草机往往会存在如下所描述的不同控制动作,以保证割草机以及附近用户的安全,或,提高割草机工作效率。当然,分别均可以与上面所描述的其他实施方式结合。
在一些实施方式中,自动割草机还可以包括:异常检测传感器,被配置为至少获取自动割草机的移动方向上的环境信息或获取自动割草机的运动姿态信息。控制器进一步被配置为:根据第一检测数据确定割草机上存在用户;根据异常检测传感器检测到的信息确定自动割草机即将或已经发生异常;在手动模式下,响应于在持续第四预设时间段内检测到割草机上不存在用户,且,割草机即将或已经发生异常,控制其退出手动模式。响应于在小于第四预设时间段内检测到割草机上无用户,且,割草机即将或已经发生异常,控制其保持手动模式。异常检测传感器可以是摄像头,被配置为检测割草机是否处于颠簸状态或前方存在凹凸的颠簸路段。手动模式下,当检测到机器处于颠簸等异常状态时,若检测到用户离开割草机的持续时间已经超过颠簸腾空的正常时间范围(即,大于等于第四预设时间段)时,确定用户已完全离开座椅,此时控制割草机退出手动模式,以保证割草机附近用户的安全;当持续时间较短(即,小于第四预设时间段,例如:小于5s)时,控制割草机保持手动模式,从而避免将短暂的弹起离开座位误认为是退出手动状态。通过准确识别用户的骑乘状态,保证在异常状态下操纵割草机的稳定性。进一步的,通过设定时间范围可以避免因短暂的颠簸腾空导致错误的退出手动模式,提高割草机识别用户骑乘状态的准确性,提高用户体验。具体的异常检测手段参见文末相关内容。
在一些实施方式中,在手动模式下,响应于在第五预设时间段内检测到自动割草机上不存在用户,控制其退出手动模式,第五预设时间段大于第四预设时间段。当长时间识别不到用户,表明用户极有可能已经离开割草机,则需要退出手动模式。例如:第五预设时间段为10s。不过上述关于时间的具体数值均为举例说明,不应对本申请实施方式中的时间段产生限定作用,本申请实施方式中只需要满足上述时间关系即可。
在一些实施方式中,在手动模式下,在割草机前进的过程中,响应于根据第二检测数据识别到自动割草机前方存在障碍物,或,响应于根据定位传感器识别到自动割草机前方存在障碍物,控制自动割草机保持行驶路径或工作状态不变。即,手动模式下,割草机主要依靠用户手动遥控实现行驶,而非其他传感器。防止割草机因传感器采集的数据短时异常而出现偏航等异常反应,避免对用户造成惊吓。
在一些实施方式中,在手动模式下,控制器5在接收到第二检测元件6或定位传感器1获取到用户或障碍物的检测数据时,为了避免用户因未注意到该障碍物而使得骑乘式割草机与该障碍物发生碰撞,可向用户输出提醒消息,比如触发骑乘式割草机上的报警装置发出报警声、或者通过控制面板输出有障碍物的文字提醒消息等,或者在某些特殊情况下,如,割草机距离障碍物很近却未识别到用户任何改变割草机路径的操作时,控制割草机紧急刹车。此外,为了控制割草机在自动模式能主动避开手动模式时曾经遇到的障碍物,控制器5可记录用户或障碍物的位置信息,并更新地图,例如:在地图上标识出障碍物等。如此,提高了骑乘式割草机的安全性以及用户使用体验。
在一些实施方式中,在手动模式下,控制自动割草机后退的过程中,响应于根据第二检测数据识别到至少后退方向上存在障碍物,或,响应于根据定位传感器识别到自动割草机后退方向上存在障碍物,控制自动割草机发出警报或向用户端发送通知消息。防止用户由于没及时看到后方行人或障碍物而发生碰撞,造成不安全情况。
在一些实施方式中,在手动模式下,骑乘式割草机按照用户输入的行驶方向或行驶速度行驶的过程中,若长时间检测不到输入操作指令,可以控制骑乘式割草机退出手动模式。如此,防止发生由于用户走神导致割草机撞击附近用户的不安全现象。
在一些实施方式中,在手动模式下,当检测到大于或等于预设时长内未接收到运动调整部4输入数据时,控制器5向运动调整部4发出锁定指令或向切割部3发出停止切割指令。
可以理解,在手动模式下,当检测到大于或等于预设时长内未接收到运动调整部4输入数据时,可能是用户正在骑乘式割草机上休息或玩手机等,为了防止因其他用户突然操作运动调整部4而保护用户和骑乘式割草机的安全,控制器5可向运动调整部4发出锁定指令,以无法根据运动调整部4输入的行驶方向控制骑乘式割草机行驶,或向切割部3发出停止切割指令,以使切割部3停止执行割草操作。
在一些实施方式中,在自动模式下,控制骑乘式割草机自动沿规划路径行驶的过程中,响应于在持续第二预设时间段内识别到自动割草机前方存在障碍物,控制自动割草机终断任务进程,第二预设时间段小于第一预设时间段。控制第二预设时间段小于第一预设时间段,保证割草机可以正常启动以执行割草工作。因为若第二预设时间段大于第一预设时间段,割草机对障碍物检测的响应时间要求变长,可能导致无法及时终止任务进程,从而发生撞击障碍物等不安全情况。
其中,第二预设时间段可以根据实际情况需要进行设置,比如可以设置为10s、15s等小于第一预设时间段的时间。进一步的,当确定骑乘式割草机发生接触式碰撞时,控制其停止行驶。
可选地,骑乘式割草机还包括待机模式,待机模式是指控制器5处于任务进程终断或终止的状态。骑乘式割草机自动沿规划的路径行驶的过程中,控制器5会实时或不定时获取第二检测元件6对骑乘式割草机前进方向是否有障碍物的第二检测数据,或者,获取定位传感器1对骑乘式割草机前方是否有障碍物的检测数据。当确定在第二预设时间段内持续检测到障碍物时,说明割草机长时间检测到障碍物且可能无法避开障碍物,可以控制骑乘式割草机终断移动以及割草等任务进程,并进入待机模式。例如,割草机自动移动的过程中,第二检测元件长时间识别到狗在前方,则控制割草机暂时停止移动和割草。
在一些实施方式中,在自动模式下,骑乘式割草机自动沿规划路径行驶的过程中,当小于第三预设时间段内检测到用户或障碍物时,控制骑乘式割草机避开用户或障碍物,并自动沿规划的路径继续行驶。第二预设时间段大于第三预设时间段。其中,可以根据实际情况需要设置第三预设时间段,比如:可以设置为2s、3s等小于第二预设时间段的时间。可以理解,在自动模式下,骑乘式割草机自动沿规划的路径行驶的过程中,控制器5会实时或不定时获取第二检测元件6对骑乘式割草机前进方向是否存在用户或障碍物的第二检测数据。当确定小于第三预设时间段内检测到用户或障碍物时,可以控制骑乘式割草机避开障碍物。通过主动避开短时障碍物,提高了骑乘式割草机的灵活性和安全性。
割草机针对上面所描述的异常情况的控制动作可以单独存在,也可以组合存在于割草机中,本申请的实施方式中对此不作限定。通过这些控制动作可以保证割草机以及附近用户的安全,或,提高割草机工作效率。
在一些实施方式中,在手动模式下,控制器5仅根据用户指令工作,检测到障碍物也不改变骑乘式割草机的行驶路径或工作状态。在手动模式下,控制器5控制骑乘式割草机执行以下至少之一的操作,包括:获取第二检测元件6检测到的障碍物信息,以及,获取检测到障碍物时的位置信息,并在地图中进行标记,以用于后续自动模式下的路径规划。需要说明的是,定位传感器1和第二检测元件6可以是只获取检测数据但不对检测数据进行处理,也可以是既能获取检测数据也能对检测数据进行处理。例如,定位传感器1和第二检测元件6可能是只获取骑乘式割草机周围是否有障碍物的检测数据,也可能是对获取的检测数据进行处理,生成骑乘式割草机周围有障碍物或者无障碍物的检测数据。
在一些实施方式中,在手动模式下,控制器5记录第二检测元件6获取到的自动割草机周围存在障碍物的检测结果,或,记录定位传感器1获取到的自动割草机前方存在障碍物的检测结果,并根据所记录的检测结果更新地图。
在一些实施方式中,当割草机在自动模式下终断任务进程时,可以控制其在识别不到障碍物之后,继续移动。保证割草机的灵活作业。
在另一些实施方式中,当割草机在自动模式下终断任务进程时,也可以在响应于接收到用户指令,继续行驶。
在一些实施方式中,退出手动模式后,可以控制自动割草机停止移动和割草工作。当检测到割草机停止移动时,如果识别到承载件上存在用户,且接收到至少一个用户确认指令,则响应于接收到运动调整部的输入,控制割草机移动和工作。当检测到割草机未停止移动时,如果识别到承载件上存在用户,则响应于接收到运动调整部的输入,控制割草机移动和工作。其中,用户确认指令与上文中描述的指令一致,如:确认按键的触发或者获取到密码。
在另一些实施方式中,退出手动模式后,如果识别到承载件上存在用户,则响应于切换至自动的确认指令,控制割草机进入自动模式。
在另一些实施方式中,在退出手动模式或在自动模式下,运动调整部失效,从而避免非自动模式时,人机操控模块被树枝或用户等误触碰,从而机器根据误触碰的结果进行误操作,给用户或环境中的活物带来安全风险。
在一些实施方式中,在手动模式下,根据运动调整部4输入的行驶方向或行驶速度控制骑乘式割草机行驶。当退出手动模式或在自动模式下,无法根据运动调整部4输入的行驶方向或行驶速度控制骑乘式割草机行驶,即,运动调整部失效。通过控制运动调整部失效,防止运动调整部4被树枝或用户等误触碰,从而根据误触碰的结果进行误操作,给用户或环境中的活物带来安全风险。
在手动模式下,用户通过运动调整部4输入行驶方向或行驶速度,以控制骑乘式割草机按照用户意图进行移动和工作。在退出手动模式或在自动模式下,响应于运动调整部的输入,控制自动割草机保持行驶方向不变,以沿规划的路径行驶。即,无法根据运动调整部4输入的行驶方向或行驶速度控制骑乘式割草机行驶。其中,运动调整部4包括摇杆等,控制器5将不会响应于用户通过摇杆的输入执行任何操作。进一步的,骑乘式割草机还可以包括用于调整骑乘式割草机行驶速度的速度控制器,当割草机在退出手动模式或进入自动模式后,控制器5也不会响应于用户输入调整行驶速度,速度控制器也可以是摇杆,通过摇杆控制割草机调整方向以及速度。
在一些实施方式中,人机操作模块还可以包括:用户界面,用户界面包括:操作键。控制器进一步被配置为:当退出手动模式或在自动模式下,控制操作键失效。其中,操作键不包括停机按键。即,在自动模式下,响应于操作键的输入,控制自动割草机保持行驶方向或行驶速度不变。
在一些实施方式中,自动割草机包括:人机操作模块,用户通过人机操作模块与自动割草机交互,控制器进一步被配置为:在退出手动模式或进入自动模式之后,控制人机操作模块位于收纳位;在进入手动模式之后,控制人机操作模块位于工作位。通过控制人机操作模块处于收纳位,从而在退出手动模式或进入自动模式之后,用户无法操作人机操作模块。
在一些实施方式中,用户界面上设置有操作键。割草机上设置有保护罩,可开合地罩设在操作键上。控制器进一步被配置为:在退出手动模式或在自动模式下,控制保护罩合上;在手动模式下,控制保护罩打开。通过控制操作键上的保护罩合上,从而在退出手动模式或进入自动模式之后,用户无法操作操作键。
下面对割草机处于不同工作状态时的速度情况进行说明。当然,分别均可以与上面所描述的其他实施方式结合。
在一些实施方式中,在手动模式下,在建图状态下,控制器5根据接收到的建图指令控制割草机沿工作区域的边界行驶。在行驶过程中,根据定位传感器采集的位置信息建立工作区域的地图。骑乘式割草机可以包括控制面板,该控制面板上设置有用于触发建图模式的建图按键。在建图按键被触发后,控制器5将接收到建图指令。此外,用于对骑乘式割草机进行控制的APP上也设置有建图按键,用户在触发该建图按键后,APP将向骑乘式割草机发送建图指令。
在一些实施方式中,在手动模式下,控制自动割草机在建图状态下的最大行驶速度小于等于在工作状态下的行驶速度。控制建图状态下的行驶速度小于或等于其割草时的最大行驶速度,以保证骑乘式割草机能够更准确地沿工作区域的边界行走,提高了所建立的工作区域的地图的准确性以及骑乘式割草机的安全性。其中,骑乘式割草机割草时的最大行驶速度可以根据实际情况需要进行设置,比如可以设置为1m/s等。
在一些实施方式中,接收到建图指令时,控制器5获取第一检测元件2的第一检测数据,在根据第一检测数据确定骑乘式自动割草机上存在用户的情况下,控制器5控制骑乘式割草机根据用户指令控制其沿边界行驶;当根据第一检测数据确定骑乘式割草机上无用户时,控制器5控制其停止沿着工作区域的边界行驶,并停止建立工作区域的地图。
进一步的,控制器5在停止建立工作区域的地图后,可向APP发送对应的提醒消息,以使APP通过弹窗显示继续建图以及结束建图两个操作入口,从而可方便用户基于需求选择相应操作入口进行处理。这里,如果骑乘式割草机和APP在预设时长如90分钟内没有接收到任何操作,则控制器5可结束建图。此外,控制器5在停止建立工作区域的地图后,也可向关联终端发送用于提示是否结束建图和/或继续建图的提示消息,并根据所述关联终端发送的反馈消息进行相应处理。其中,关联终端可以为与骑乘式割草机已绑定或建立通信连接的终端。
在一些实施方式中,控制割草机在手动模式下的最大行驶速度大于自动模式下的最大行驶速度。在自动模式下设置较低的行驶速度,防止割草机撞击行人等不安全现象,以在保证骑乘式割草机安全性的前提下,提高工作效率。在完成第一家客户的割草工作后,用户需要驾乘割草机转场去往另一家客户执行割草工作,在手动模式下设置更大的行驶速度,能够提高去往另一家客户的速度,缩短中途的转场时间。例如,设置手动模式下最大行驶速度为5m/s,设置自动模式下最大行驶速度为2m/s。
在一些实施方式中,在手动模式下,可以设置割草机转场时的行驶速度大于正常割草工作时的最大行驶速度。以保证手动控制割草机正常移动过程中的安全。例如,设置正常割草工作时的最大行驶速度为3m/s。
在一些实施方式中,控制器5控制骑乘式割草机后退时的行驶速度小于或等于前进时的最大行驶速度。在手动模式时,后退时的行驶速度小于或等于前进时的最大行驶速度;在自动模式时,后退时的行驶速度小于或等于前进时的最大行驶速度。由于骑乘式割草机后退时,对骑乘式割草机的控制与工作时比可能不够灵活。因此,控制器5控制割草机后退时,可控制骑乘式割草机后退时的行驶速度小于或等于前进时的最大行驶速度。
在一些实施方式中,割草机的存储器中存储有与各个工作状态关联的最大行驶速度,通过识别割草机所处的工作状态,控制割草机切换至不同的最大行驶速度。割草机可以自动根据不同工作状态切换至对应的最大行驶速度。例如,识别到割草机在转场时,将最大行驶速度切换至转场场景下的速度;识别到割草机在自动模式下前进时,将最大行驶速度切换至自动模式下前进的速度;识别到割草机在自动模式下后退时,将最大行驶速度切换至自动模式下后退的速度。
在一些实施方式中,割草机的存储器中存储有与各个工作位置关联的最大行驶速度,通过识别割草机所处的工作位置,控制割草机切换至不同的最大行驶速度限制情况。割草机可以自动根据不同工作位置切换至对应的最大行驶速度。例如,识别到割草机在转场对应位置时,将最大行驶速度切换至转场场景下的速度;识别到割草机在工作区域对应位置时,结合工作状态将最大行驶速度切换至自动模式或手动模式下的速度。
在一些实施方式中,骑乘式割草机中设置有待机模式。在待机模式下,控制器5处于任务进程终断,终止,或,未接收到任务指令的状态。当骑乘式割草机处于待机模式或接收到停止切割的指令时,控制器5配置为将切割部3调整至竖直方向上的最高位置。
当骑乘式割草机处于待机模式或接收到停止切割的指令时,为了保护切割部3以及防止用户因未注意到切割部3而误碰触的风险,控制器5将切割部3调整至竖直方向上的最高位置。需要说明的是,在待机模式下,控制器5可接收对切割部3的高度调整指令,但不会对切割部3的高度进行调整。
在一些实施方式中,当骑乘式割草机从待机模式切换至自动模式时,控制器5配置为根据在待机模式下接收的关于切割部的高度调整指令,将切割部调整至高度调整指令所要求的高度。
其中,关于切割部的高度调整指令可以是用户通过骑乘式割草机的控制面板输入的,也可以是用户通过APP输入并由APP向骑乘式割草机发送的。由于在待机模式下骑乘式割草机可能不会对障碍物等进行检测,为了防止障碍物损坏切割部,控制器5在骑乘式割草机从待机模式切换至自动模式时,才根据在待机模式下接收的关于切割部的高度调整指令,将切割部调整至高度调整指令所要求的高度。如此,提高了骑乘式割草机的安全性。
在一些实施方式中,切割部3包括至少两个切割件,至少两个切割件被配置为根据所接收到的切割指令执行割草操作;切割部3根据接收到的切割指令依次启动至少两个切割件。在手动模式和自动模式下,至少两个切割件在启动割草时将依次启动,以防止因同时启动造成电流过大,导致出现过流问题。这里,相邻启动的切割件的时间间隔可以根据实际情况需要进行设置,比如可以设置为2s等。如此,通过依次启动切割件,提高了骑乘式割草机的安全性。
在本申请的实施方式中,至少响应于识别到骑乘式割草机上存在用户,控制骑乘式割草机进入手动模式。通过至少在识别到骑乘式割草机上存在用户,才控制骑乘式割草机进入手动模式,避免手动模式下,如果用户未处于正确的驾驶位置就去操控机器时所带来的安全风险,实现在高效切割且保证使用者安全的同时,自动切换自动割草机的工作模式,提升了用户使用体验。
下面通过一个具体的应用场景对本申请实施方式中的自动割草机进行说明。
在雇佣者接收到要维护客户家花园的工作任务时,会先建立客户家花园的边界地图。建立地图时,自动割草机处于手动模式。具体的,用户打开自动割草机的靠背坐上去。自动割草机的控制面板弹出请确认进入手动模式的对话框,雇佣者点击确认。点击“摇杆”按钮,输入密码。密码正确,则允许雇佣者使用摇杆控制自动割草机沿着边界行驶。通过定位传感器采集行驶过程中的位置信息,以建立边界地图。在自动割草机沿着边界行驶完一圈之后,控制自动割草机生成地图或者在云端生成地图并保存。后续雇佣者会按照规则去客户家维护花园。雇佣者操作自动割草机到达客户家的割草区域,可选择离开座椅,并合上靠背,退出手动模式,进入自动模式。在自动模式下,控制面板上会显示“请在APP中下载地图”的提示,APP会自动检索附近的地图,雇佣者选择客户家花园所在地图,点击下载以下载地图至割草机。一旦自动割草机下载完地图,屏幕就会显示“成功”。点击自动割草机控制面板上的start按键以及ok按键,并远离割草机。当割草机识别不到用户时,控制器控制其自动按照地图开始工作。如果在割草过程中需要停机,则按下自动割草机上的停止按钮或在APP中选择停止,自动割草机将立即停止工作。当需要自动割草机继续割草时,则选择start按键以及ok按键,则割草机将继续执行自动割草工作。割完草后,自动割草机将回到起点等待,从而雇佣者可以驾驶自动割草机去附近的客户家工作。
基于前述实施方式相同的发明构思,本申请实施方式提供了一种自动割草机的控制方法,参阅图4,为本申请实施方式提供的一种方法,该方法可以由本申请实施方式提供的一种自动割草机来执行,该装置可以采用软件和/或硬件的方式来实现,本实施方式中以该方法的执行主体为自动割草机为例,本实施方式提供的方法包括:
步骤S401:获取自动割草机上是否存在用户的第一检测数据。
其中,可通过压力传感器、图像传感器等检测元件实时或周期性获取自动割草机上是否存在用户的第一检测数据。
步骤S402:至少响应于识别到自动割草机上存在用户,控制自动割草机进入手动模式;在手动模式下,自动割草机沿用户输入的路径或方向行驶。
其中,当根据第一检测数据确定自动割草机上存在用户时,说明此时用户希望手动操控自动割草机,至少根据表征自动割草机上存在用户的信号,进入手动模式,以使自动割草机沿用户输入的行驶方向或行驶速度行驶。
此外,至少根据第一检测数据确定自动割草机上无用户,控制自动割草机进入自动模式;在自动模式下,自动割草机至少基于位置信息控制其自动沿规划的路径行驶。
需要说明的是,本实施方式提供的自动割草机的控制方法的具体实施过程可参考前述实施方式中对自动割草机的描述,在此不再赘述。
综上,上述实施方式提供的自动割草机的控制方法中,通过至少在识别到骑乘式割草机上存在用户,才控制骑乘式割草机进入手动模式,避免手动模式下,如果用户未处于正确的驾驶位置就去操控机器时所带来的安全风险,实现在高效切割且保证使用者安全的同时,自动切换自动割草机的工作模式,提升了用户使用体验。
在一些实施方式中,还提出了根据承载件的状态控制割草机执行相应操作的技术方案。具体的细节如下。
如图8-11所示,自动割草机包括:承载件,安装于机身,被配置为承载用户,承载件包括:座椅或站板,承载件至少包括两种位置状态:收折状态以及展开状态;第一检测元件,安装于机身,被配置为获取承载件的位置状态信息;控制器,与第一检测元件信号相连,被配置为接收位置状态信息;控制器还被配置为:至少响应于根据位置状态信息确定承载件处于展开状态,控制自动割草机进入手动模式;至少响应于根据位置状态信息确定承载件处于收折状态,控制自动割草机进入自动模式。

如下为具体的异常检测手段等内容。
下述以颠簸状态为例进行详细说明。具体的,机身为机器人的主体结构,座位用于承载用户骑乘,用于获取竖直加速度数据的传感器和压力数据的传感器设置在座位处,具体的是竖直加速度传感器用于获取座位的竖直加速度,压力传感器用于获取座位的压力。首先确认机器人正在骑乘模式下,并判断是否处于颠簸状态,在确认机器人在颠簸状态后,当用户离开座位的时间已经超过正常的颠簸腾空的时间范围时,则确定用户已经完全的离开座位,退出骑乘模式。通过设定时间范围,即第一预设时长,可以避免因短暂的颠簸腾空导致错误的将骑乘模式转换为非骑乘模式,提高识别用户骑乘状态的准确性。
在一些实施方式中,异常检测传感器可以包括用于检测承载件上的压力的压力传感器以及用于检测承载件至少在竖直方向上的加速度分量的加速度传感器。控制器被配置为基于压力传感器检测的承载件上的压力,确定用户离开承载件的时间段;控制器被配置为基于加速度传感器检测的承载件在竖直方向的加速度分量,确定机器用户是否处于颠簸状态。在一较佳实施方式中,加速度传感器为imu传感器,用于获取承载件在竖直方向上的加速度。在其他实施方式中,检测传感器还可以为同时检测承载件上的压力和竖直方向上加速度的传感器或者识别机器用户周围环境的摄像头、超声传感器等,在此不做具体限定。下面的实施方式中,一般以承载件为驾驶座椅为例进行说明。
具体的,用户在承载件上的状态可以通过压力传感器的数值或相位表示,根据压力传感器的结果在时间顺序上的规律,可以得到用户离开承载件的时间段,另外,在颠簸和非颠簸状态下,承载件的竖直加速度具有不同的数值范围,由加速度传感器实时的检测承载件座椅在竖直方向上的加速度,其中超出非颠簸状态下的竖直加速度范围的部分即为颠簸状态。压力传感器和加速度传感器可以实时快速的得到压力和竖直加速度在时间顺序下的变化。
在本申请的一些实施方式中,还可以包括以下步骤:座椅在颠簸状态下,用户具有两种可能的状态,分别是用户坐在座椅上或用户离开座椅,其中用户离开座椅可能是由于颠簸弹起,短暂的离开;另一种可能为用户退出骑乘,因此需要确认用户在骑乘模式(也就是上文中的手动模式)时离开座椅,并判断机器用户是否在颠簸状态。当机器用户在颠簸状态下利用第四预设时间段判断是否退出骑乘;其中第四预设时间段基于用户在颠簸下腾空的短暂时长确定,其可以大于或等于用户在颠簸下腾空的一般时间段。用户离开座椅的时间已经超过第四预设时间段时,即已超过正常的颠簸腾空的时间范围时,则确定用户已退出骑乘,机器用户退出骑乘模式;如用户在第四预设时间段内就回落到座椅上时,则表示用户正在骑乘状态,检测到的离开座椅仅为短暂腾空,不需要退出骑乘模式。结合用户离开座椅的时长的确认用户是退出骑乘还是颠簸腾空,再进行骑乘模式和非骑乘模式的切换,避免因短暂的颠簸腾空导致判断错误。
在本申请一些实施方式中,通过检测座椅上的压力判断用户是否离开座椅。
具体的,当机器用户行驶时,座椅上的压力是动态变化的,可以将座椅上的压力状态划分为三种,分别是用户完全坐位座椅上,用户完全离开座椅和用户未完全坐下且未完全离开座椅。
在本申请一些实施方式中,检测座椅上的压力包括通过压力传感器检测座椅上的压力。
具体的,压力传感器具有信息采集口,表示为io口,io口配置为输入模式,输入值为0和1。
在具体实施方式中,压力传感器设置有两个,如图6所示,T_SEAT_P1和T_SEAT_P2分别为两个压力传感器,IO_SEAT_P1、IO_SEAT_P2分别为两个信号采集io口,T_SEAT_P1为设置在接地电路中的第一压力传感器,表示为P1,T_SEAT_P2为设置在接电源电路中的第二压力传感器,表示为P2。当用户完全坐下时,P1输入值为1,P2输入值为0;当用户完全离开座椅时,P1的输入值为0,P2的输入值为1;当用户未完全坐下且未完全离开座椅时,P1和P2的输入值皆为1,或P1和P2的输入值皆为0。用户在座椅上的状态具有四种表示,分别为:10、01、11和00。因此识别用户完全离开座椅的持续时间段,即检测P1输入值为0且P2输入值为1的持续时间段。
在一些实施方式中,检测压力的方法包括通过检测应变片的应变检测压力;或利用高速摄像机观察形变检测压力;或机械装置接触座椅测量位移来计算压力中的至少一种,关于检测机器用户检测座椅压力的具体方式不做限定。
在一些实施方式中,检测座椅上的压力包括:通过检测座椅在竖直方向上的加速度的方式、通过图像识别的方式、通过陀螺仪检测角运动的方式或通过检测用户离开座椅的持续时间段的方式中的至少一种。关于检测机器用户是否处于颠簸状态的具体方式不做限定,根据实际需要进行选择即可。具体的,座椅在竖直方向上的加速度在颠簸状态下的绝对值大于在平稳状态下的数值,因此通过检测竖直方向的加速度可以判断座椅是否处于颠簸状态。通过图像识别路面的平整度或图像识别的机器用户的行驶状态都可以判断机器用户是否在颠簸状态。在颠簸状态下,机器用户与路面之间的角度也会发生改变,因此可以利用陀螺仪检测角运动进行检测。
在具体实施方式中,通过检测座椅在竖直方向上的加速度判断机器用户是否在颠簸状态。如图7所示,在实际行驶过程中,加速度会在竖直方向上波动,以平缓路段下机器用户的平稳加速度g为基准,将加速度数据分别划分为两部分数据,一是大于平稳加速度g的数据A,二是小于平稳加速度g的数据B。为了去除平缓行驶的正常加速度浮动范围,在A和B中去除在靠近平稳加速度g的数据。同时为了去除离群点对数据准确度的影响,在A和B中去除远离平稳加速度g的一段范围数据,得到颠簸数据,在颠簸数据内选取特定值作为颠簸端点,A中的颠簸端点的a,B中的颠簸端点为b,则竖直方向上的加速度大小在[-∞,b]和[a,+∞]区间的数据为颠簸区间数据,由此准确的得到颠簸区间。
具体的,将大于和小于平缓加速度g的10%以内的数据去除,即将[g-0.1,g+0.1]区间内的数据去除。将远离平缓加速度10%的数据去除,如一组加速度数据的范围处于[g-1,g+2]区间内,则需去除[g+1.8,g+2]和[g-0.9,g-1]区间数据。也就是,加速度数据的范围处于[g-1,g+2]区间内,则需去除[g-0.1,g+0.1]、[g+1.8,g+2]和[g-0.9,g-1]区间数据,然后计算A和B剩余数据的中位数,得到a和b,从而得到颠簸区间数据。
在具体实施方式中,两个压力传感器检测用户与座椅之间的状态,可以检测得到四种压力状态,分别是10、00、11、01;其表示三种座椅状态,分别是完全坐下状态(10),完全离开状态(01)和未完全坐下也未完全离开的状态(11和00),用户在座椅上的状态会影响竖直加速度的检测结果,所以三种座椅状态检测到的数据需要分别划分为三种数据范围,计算得到三种颠簸区间。因为完全离开状态下,可能包括了非骑乘状态的数据,因此选取完全坐下状态或未完全坐下未完全离开状态的颠簸区间定义骑乘模式下的颠簸状态。结合用户的座椅状态划分不同的竖直加速度的范围,进而判定颠簸状态,提高了划分颠簸区间的精度,进而提高了判断颠簸状态的准确性。
用户离开座椅的持续时间段达到第五预设时间段,控制机器用户退出骑乘模式,包括:首先获取用户完全离开座椅时,机器用户的实时加速度,实时加速度超过竖直加速度预设的范围的部分划定为腾空加速度范围,当机器用户的实际加速度处于腾空加速度范围内持续时间超过第五预设时间段时,则确认用户已退出骑乘,则控制机器用户退出骑乘模式。
具体的,取完全离开状态(01)的数据,其中具有大于平缓加速度g的数据A和小于平缓加速度g的数据B。当A和B中的竖直加速度远离平缓加速度g足够远的距离时,定义为腾空加速度范围,请参见图3,腾空加速度范围分为大于g的腾空加速度范围C和小于g的腾空加速度范围D。在腾空加速度范围中选取中位数作为确认值:在腾空加速度范围C中的数个数值中,选取中位数c作为腾空端点;在腾空加速度范围D中的数个数值中,选取中位数d作为腾空端点,因此当实时加速度在[-∞,d]和[c,+∞]的区间中时,用户在腾空状态,当腾空状态超过第五预设时间段,说明用户未在骑乘状态,则退出骑乘模式。
在具体实施方式中,如图7所示,平缓加速度为g,在数据A中远离g的10%的范围为为腾空加速度范围C;在数据B中远离g的10%的范围为为腾空加速度范围D。如一组加速度数据的范围处于[g-1,g+2]区间内,则腾空加速度范围C为[g+1.8,g+2],腾空加速度范围D为[g-0.9,g-1]。当机器用户的实际加速度处于[g+1.8,g+2]或[g-0.9,g-1]范围内持续时间超过第一预设时长时,则确认用户已退出骑乘,则控制机器用户退出骑乘模式。
当机器用户处于非颠簸状态,基于用户离开座椅的持续时间段,控制机器用户退出骑乘模式。
在非颠簸状态下,用户具有两种可能的状态,分别是短暂的更改骑乘动作或不再需要骑乘,通过用户离开的时间来判断用户的状态,如离开的时间足够长,则断定为不再需要骑乘的状态,退出骑乘模式。在非颠簸状态不存在用户颠簸腾空的情况,仅需要直接根据用户离开座椅的时长得到用户的骑乘状态,保证在非颠簸状态下,骑乘模式和非骑乘模式切换的及时性。
在本申请一实施方式中,根据异常检测传感器检测到的信息确定自动割草机未发生异常;在手动模式下,响应于在第五预设时间段内自动割草机上无用户,且,自动割草机未发生异常,控制其退出手动模式,第五预设时间段大于第四预设时间段。具体的,在非颠簸状态下,用户不会发生被动的腾空,一般为主动的改变的骑乘动作,因此第五预设时间段大于第四预设时间段,判断用户是否为改变骑乘动作临时离开座椅还是不再骑乘。
在上述实施方式中,首先确认机器用户是否在骑乘模式,再判断骑乘模式时用户是否离开座位,机器用户是否在异常状态,确认了机器用户在异常状态后,用户离开座位达到预设时间段后再确认退出骑乘模式。在异常状态下用户可能会弹起,导致短暂的离开座位,通过判断用户离开座位的时间段可以避免将短暂的弹起离开座位误认为是退出骑乘状态。通过准确识别用户的骑乘状态,保证在异常状态下操纵机器用户的稳定性。
在一些实施方式中,人机操作模块至少包括两种位置状态:收折状态以及展开状态。响应于第一检测元件检测到承载件或人机操作模块处于收折的状态,控制自动割草机进入自动模式。在自动模式下,响应于接收到用户指令,控制自动割草机沿自动规划的路径行驶。自动模式下,通过控制这些模块收缩,减小机器在空间中的占用体积,从而提升其在特殊场景的通过性以及越障能力,特殊场景例如:狭窄空间以及由低矮树枝的场景,,使得其作业场景更多元化。
在一些实施方式中,承载件或人机操作模块处于展开状态时,自动割草机具有第一尺寸;承载件或人机操作模块处于收折状态时,自动割草机具有第二尺寸,第一尺寸大于第二尺寸,第一尺寸和第二尺寸为自动割草机在空间中的任意相同方向的尺寸。
在一些实施方式中,响应于检测数据检测到承载件或人机操作模块处于展开的状态,控制自动割草机退出自动模式。
