Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application. All other embodiments, which can be made by a person skilled in the art without any inventive effort, are intended to be protected by the present application based on the embodiments of the present application.
An electronic parking system (Electrical Park Brake, EPB) can enable automatic parking of a vehicle after the vehicle has been parked. In the ramp parking process, if the electronic parking system is in a failure scene, a vehicle may slide, and potential risks of collision with a driver or other road participants exist, so that parking safety is low.
In view of the above, the application provides a parking control method, which can determine a parking area with a lower gradient in advance through a parking map, and can control a vehicle to park in the parking area with the lower gradient when the vehicle is on a slope and an electronic parking system is invalid, so that the problem of sliding is prevented, and the parking safety is improved.
In order to illustrate the technical scheme of the application, the following description is made by specific examples.
Fig. 1 shows a schematic implementation flow chart of a parking control method according to an embodiment of the present application, which is applicable to situations where parking safety needs to be improved.
It should be noted that the parking control method shown in fig. 1 may be executed by a processor, and the processor may be integrated in the vehicle or may be integrated in a separate electronic device. The electronic equipment can be intelligent equipment such as a computer, a smart phone, vehicle-mounted equipment and the like, and can be used for parking control of a vehicle. When the processor is integrated in the vehicle, the vehicle may perform autonomous parking control by the parking control method shown in fig. 1. And, the vehicle may be a new energy vehicle, a fuel oil vehicle or other types of vehicles. The application is not limited in this regard.
Specifically, the above-described parking control method may include the following steps S101 to S103.
Step S101, a parking map is acquired.
The parking map refers to an electronic map for automatic parking of a vehicle. By way of example, the parking map may be a map of the environment in which the vehicle is scanning and constructing a parking environment (e.g., a parking lot), for example, the vehicle may scan the environment and construct a parking map via a SLAM (Simultaneous Localization and Mapping, SLAM) algorithm. The parking map may also be an electronic map drawn based on a design drawing of the parking environment. And, it should be noted that the parking map may be a grid map, a vector map, or another type of map, which is not a limitation of the present application.
Step S102, determining a backup parking area of the vehicle according to the map information recorded in the parking map.
In an embodiment of the present application, map information may be recorded in a parking map, and the map information may include position information of prohibition markings (e.g., lane lines, parking space lines, etc.) within a parking environment, position information of static obstacles, gradient information of a road surface, and the like. Based on the map information, the processor may determine a backup parking area for the vehicle within the parking environment from the parking map.
The backup parking area is a safe parking area used when the parking is invalid, and the vehicle can be parked safely under unexpected conditions. Specifically, the first gradient information of the backup parking area satisfies the safe gradient condition. The first gradient information represents the gradient of the backup parking area, and when the gradient of the backup parking area is smaller than or equal to a gradient threshold value, the processor can confirm that the first gradient information of the backup parking area meets a safety gradient condition. The gradient threshold value may be set according to an empirical value, for example, may be set to 1%.
In some embodiments, the parking map may include a plurality of layers, each layer having different map information recorded therein. For example, the parking map may include a parking space map layer, a road surface map layer, a static obstacle map layer, and the like. The processor extracts a parking space line pattern layer and a road surface pattern layer from the parking map, determines a region in which the vehicle is allowed to park based on the parking space line information in the parking space line pattern layer and the obstacle information in the obstacle pattern layer, determines a region in which the gradient information satisfies the safe gradient condition in the region in which the vehicle is allowed to park based on the gradient information in the road surface pattern layer, and further takes at least one of the regions as a backup parking region.
Step S103, when the vehicle finishes parking in the target parking area, if the second gradient information of the target parking area does not meet the safety gradient condition and the electronic parking system of the vehicle is detected to be in a fault state, the vehicle is controlled to move to the backup parking area for parking.
In an embodiment of the application, the vehicle may be automatically parked in response to a user-triggered automatic parking request. The target parking area is a target location for automatic parking, and may be a user-set parking area (e.g., a user's parking space), or a nearest parking space confirmed by the automatic parking system from around the vehicle.
Specifically, the vehicle may be configured with an automatic parking system, an electronic parking system, and a power system. As shown in fig. 2, the automatic parking system may collect environmental information around the vehicle by sensing sensors configured in the system, plan a parking route based on the environmental information, and send an acceleration/deceleration request, a gear request, and an EPB request to a brake controller configured in the automatic parking system, so that the vehicle completes automatic parking according to the parking route. When the acceleration request is an acceleration request, an acceleration module of the brake controller may convert the acceleration request to a positive torque for output to a vehicle powertrain. When the acceleration and deceleration request is a deceleration request, the deceleration module of the brake controller can convert the deceleration request into braking torque to be output to the hydraulic module for decelerating the vehicle. For a gear request, a gear module of the brake controller may relay the gear request to a vehicle powertrain. For EPB requests, the brake controller can transfer the EPB requests to the electronic parking system to perform parking control of the vehicle. The power controller of the vehicle powertrain is operable to accelerate the vehicle in response to an acceleration request from the brake controller and to perform a vehicle gear change in response to a gear request from the brake controller. The automatic parking system may transmit a monitoring signal to the power sensor to perform parking status monitoring to confirm whether automatic parking is completed.
When the vehicle completes parking in the target parking area, the vehicle can detect a system state of an electronic parking system of the vehicle, and parking control is performed according to second gradient information and the system state of the target parking area.
The second gradient information represents the gradient of the target parking area, and the processor can acquire the second gradient information through a parking map, and can acquire the second gradient information through sensors such as an inertial measurement unit (Inertial Measurement Unit, IMU) and an infrared probe.
In some embodiments, if the electronic parking system detects a link failure or a hardware failure through self-detection, or the external controller cannot receive a signal sent by the electronic parking system, it may be determined that a system state of the electronic parking system is a failure state, where the failure state indicates that the electronic parking system has a failure.
When the gradient of the target parking area is greater than the gradient threshold value, for example, when the gradient is greater than 1%, the vehicle is indicated to have a sliding slope danger in the target parking area, and at the moment, the second gradient information of the target parking area can be confirmed to not meet the safety gradient condition. If the electronic parking system of the vehicle is detected to be in a fault state at this time, which indicates that the electronic parking system is in a failure scene and cannot be locked according to the EPB request to prevent the vehicle from sliding, the processor can control the vehicle to move to the backup parking area to park, so that the vehicle is prevented from sliding in the target parking area.
Specifically, the vehicle may perform path planning based on the parking map, determine a route from the target parking area to the backup parking area, and control the vehicle to move to the backup parking area based on the route to park.
In the embodiment of the application, the backup parking area of the vehicle is determined by acquiring the parking map and according to the map information recorded in the parking map, when the vehicle finishes parking in the target parking area, if the second gradient information of the target parking area does not meet the safety gradient condition and the electronic parking system of the vehicle is detected to be in a fault state, the vehicle is controlled to move to the backup parking area of which the first gradient information meets the safety gradient condition for parking, so that the vehicle is controlled to move to a position with a lower gradient for parking when the vehicle parks on a slope and the electronic parking system is in a failure scene, the problem of sliding of the vehicle is prevented, and the parking safety is improved.
In the embodiment of the application, the vehicle may be automatically parked by using a self-created map, or may be automatically parked by using a known map.
Specifically, for a vehicle that automatically parks by adopting a self-map mode, a parking map is an electronic map constructed according to the first sensor information. At this time, the electronic map is a local map of the parking environment. The first sensor information is information acquired in advance according to a vehicle sensor. The vehicle sensor is arranged on the vehicle, can be a sensor with environmental information acquisition capability such as a laser radar and a camera, and can acquire information in the moving process of the vehicle. The processor may perform a self-building map based on the first sensor information acquired in advance by the vehicle sensor and determine a backup parking area of the vehicle.
Considering that a certain field of view blind area exists in a vehicle sensor such as a laser radar and a camera, a certain information loss exists in an initial parking map, and a certain information update exists between the current time and the acquisition time of the first sensor information in the parking environment, therefore, the backup parking area determined based on the initial parking map is not necessarily the optimal backup parking area, for example, the backup parking area may be far away from the target parking area or the path substitution value moving to the backup parking area is high, therefore, as shown in fig. 3, in some embodiments, after determining the backup parking area of the vehicle according to the map information recorded in the parking map, the following steps S301 to S302 may be further included.
Step S301, updating map information of a parking map according to second sensor information acquired by a vehicle sensor during a process that the vehicle moves to a target parking area.
In the embodiment of the application, the vehicle sensor can acquire information in real time in the process of moving the vehicle to the target parking area, so as to obtain the second sensor information. The second sensor information collected by the vehicle sensor such as the laser radar and the camera can comprise new sensor information besides the first sensor. At this time, the processor may update map information of the parking map according to second sensor information acquired by the vehicle sensor.
Step S302, according to the updated map information, the backup parking area is adjusted.
Specifically, the updated map information may include new parking space line information, new static obstacle information, and new gradient information. Based on the updated map information, the processor may analyze from the parking environment whether a new backup parking area exists, and if the new backup parking area exists, may adjust the backup parking area, and adjust the original backup parking area to the new backup parking area.
In some embodiments, the processor may compare the new backup parking area with the original backup parking area, and select whether to adjust the backup parking area according to the comparison result.
Specifically, if the distance between the new backup parking area and the target parking area is smaller than the distance between the original backup parking area and the target parking area, the processor may adjust the original backup parking area to the new backup parking area. Or if the path cost of the target parking area to the new backup parking area is smaller than the path cost of the target parking area to the original backup parking area, the processor may adjust the original backup parking area to the new backup parking area. Wherein the path cost value is related to the path length, the number of turns, etc.
In this way, in the process of automatic parking of the vehicle, the processor can continuously adjust the backup parking area along with updating of the parking map, and when the second gradient information of the target parking area does not meet the safety gradient condition and the electronic parking system of the vehicle is detected to be in a fault state, the processor controls the vehicle to move to the adjusted backup parking area for parking.
For vehicles that automatically park using known maps, the parking map is an electronic map pre-built for the target area. The target area, that is, the parking environment, can cover the target parking area. For example, when the target parking area is a parking space of a parking lot, the target area may refer to the parking lot; when the target parking area is a temporary parking spot, the target area may refer to a road on which the temporary parking spot is located.
For the target area, the staff can usually complete the pre-construction of the high-definition electronic map through the design drawing or the scanning equipment performs the scanning in advance. At this time, the parking map records complete information of the parking environment, and the processor can search for a backup parking area based on the pre-constructed parking map.
Specifically, as shown in fig. 4, in some embodiments, determining the backup parking area of the vehicle according to the map information recorded in the parking map may include the following steps S401 to S402.
Step S401, extracting gradient information of each parking-capable area in the target area according to the map information recorded in the parking map.
Specifically, the map information recorded in the parking map may include parking space line information, static obstacle information, gradient information, and the like in the entire target area. Based on the parking spot line information and the static obstacle information, the processor may determine respective parkable areas within the target area. A parkable area is an area in which a vehicle is allowed to park, for example, a parking space. After determining each parkable region, gradient information of each parkable region may be extracted.
In step S402, the parkable area whose gradient information satisfies the safe gradient condition is confirmed as the backup parking area.
Specifically, using the gradient information, the processor may compare the gradient of each of the parkable areas with a gradient threshold, and if the gradient is less than the gradient threshold, may confirm that the corresponding parkable area satisfies the safe gradient condition, and confirm that the parkable area whose gradient information satisfies the safe gradient condition is the backup parking area. At this time, the gradient information of the parking area, that is, the aforementioned first gradient information, is backed up.
In some embodiments, when determining the backup parking area of the vehicle according to the map information recorded in the parking map, the processor may use a parkable area which is closest to the target parking area and whose gradient information satisfies the safe gradient condition as the backup parking area according to the map information recorded in the parking map.
In other embodiments, when determining the backup parking area of the vehicle according to the map information recorded in the parking map, the processor may use the parked area with the most gentle gradient as the backup parking area according to the map information recorded in the parking map, where the gradient information satisfies the safe gradient condition.
The application is not limited in the manner in which the backup parking area is determined.
In this way, the processor may analyze the optimal backup parking area by using the known map, and when the second gradient information of the target parking area does not meet the safe gradient condition and the electronic parking system of the vehicle is detected to be in a fault state, control the vehicle to move to the optimal backup parking area for parking.
The processor may further analyze a usage scenario of the vehicle during control of the movement of the vehicle to the backup parking area. Specifically, the usage scenario of a vehicle may be classified into a driver inside the vehicle and a driver outside the vehicle. Because the driver can avoid the vehicle to slide by taking over the vehicle, and the difficulty level of taking over the vehicle by the driver is different under different use scenes, the processor can adopt different control modes under different use scenes.
Specifically, as shown in fig. 5, the above-mentioned control of the vehicle to move to the backup parking area for parking may include the following steps S501 to S502.
Step S501, the current position of the driver is detected.
The current position of the driver can be detected by a driving detection system (DriverMonitorSystem, DMS) configured by the vehicle, and the driving detection system can analyze whether the driver is positioned at a driving position or not by a weight sensor or an in-vehicle camera. The current position of the driver can also be determined according to the distance between the remote control device and the vehicle when the driver performs remote control parking. The application is not limited in this regard.
Step S502, if the current position of the driver is located outside the vehicle, the vehicle is controlled to move to the backup parking area for parking, and take over prompt information is output.
If the current position of the driver is located outside the vehicle, the driver needs to return to the vehicle and take over the vehicle. In the process that the driver returns to the vehicle, the vehicle may slip due to incomplete parking of the vehicle, and in order to avoid the slip, the processor may directly control the vehicle to move to the backup parking area for parking, and output the take-over prompt information.
Specifically, the processor may send the takeover prompt information to the application software on the mobile phone through instant communication with the mobile phone of the driver, or output the takeover prompt information through the display system of the vehicle, the vehicle-mounted sound system, the output component of the vehicle such as the loudspeaker, etc., so as to prompt the driver to trigger the takeover control signal through the control component in the vehicle. The control assembly may refer to a steering wheel, a brake pedal, etc., and the driver may trigger the take over control signal by turning the steering wheel and stepping on the brake pedal. In response to the take over control signal, the vehicle may exit the auto park function, taking over vehicle control by the driver.
After controlling the vehicle to move to the backup parking area for parking, the processor may further control the motor to stop outputting the creep torque, and shift the gear of the vehicle to N (neutral) or P (park) to control the vehicle to be stationary in the backup parking area. After the shift of the vehicle to the N range or the P range, the processor may output the take-over cue signal again.
Therefore, the vehicle can wait for the user to take over at the position (namely the backup parking area) where the vehicle is not easy to slide, and the parking safety can be improved.
In other embodiments, if the driver's current location is within the vehicle, the processor may output a take over prompt and control the vehicle to rest in the target parking area.
Specifically, the processor may control the vehicle to rest in the target parking area via a brake controller and/or a power controller of the vehicle. The hydraulic module of the brake controller can generate hydraulic pressure, and the hydraulic pressure is transmitted to each wheel brake assembly through a pipeline by the brake fluid, so that certain force is applied to the wheels to control the vehicle to be stationary in a target parking area. The power controller can calculate the required negative torque according to the second gradient information, and control the motor to output the negative torque. When the motor outputs negative torque, the motor rotates reversely to provide reverse torque for wheels, so that the effect of controlling the vehicle to be stationary in a target parking area is achieved.
And recording the duration that the vehicle is stationary in the target parking area, and if the duration is longer than a preset duration threshold value and the vehicle does not receive a take-over control signal triggered by a driver, controlling the vehicle to move to the backup parking area to park.
The time period threshold may be set according to practical situations, for example, 1 minute.
That is, when the driver is in the vehicle, the driver can take over the vehicle in time, the processor outputs the take-over prompt message preferentially and controls the vehicle to wait in situ, and the driver can control the take-over prompt message by himself. If the driver does not take over for a long time, the vehicle is controlled to wait for the user to take over at a position where the vehicle is not easy to slide, namely, a backup parking area, so that the parking safety is improved.
Similarly, after controlling the vehicle to move to the backup parking area for parking, the processor may further control the motor to stop outputting the creep torque, and switch the gear of the vehicle to N or P to control the vehicle to be stationary in the backup parking area. After the shift of the vehicle to the N range or the P range, the processor may output the take-over cue signal again.
For ease of understanding, the following table shows the parking control process of the vehicle:
According to the embodiment of the application, the safety parking environment is provided for the vehicle by utilizing the backup parking area under the parking failure scene according to different sources of the parking map and whether the driver is in the vehicle or not, so that the reliability of the automatic parking function and the parking safety can be ensured.
