Background
In order to facilitate and make safer the driving of a motor vehicle, it is desirable to avoid having the driver force his or her line of sight to be diverted from the road on which he or she is walking. For this purpose, it is known practice to use head-up displays, adapted to project information (speed of the vehicle, direction to go, malfunction of the engine, presence of obstacles, etc.) at the height of the driver's line of sight. Two types of head-up displays are particularly known. A first type of display uses an image forming device comprising a diffuser and a scanning unit designed to generate a light beam that scans the input face of the diffuser. Thus, the light beam at the output of the diffuser forms an image, which can then be projected into the field of view of the driver of the vehicle. A second type of display uses a screen that allows an image to be generated and then projected into the driver's field of view. The variety of information that can be projected into the driver's field of view is so large that it is necessary to select those information items that are most useful to the driver. In practice, it is possible to display information related to the operation of the vehicle (speed, petrol level, automatically adjusted speed) or guidance information (road to go, distance to the next fork, name of the road being travelled, risk of traffic congestion, etc.) or even safety information (highlighting obstacles, speed limits, etc.). Currently, only a few rare items of information are selected to project into the driver's field of view in order not to overload the driver with information and not to disturb the driver too much while driving. There are many head-up display devices with different functions in the prior art.
For example, patent document No. CN108459415A discloses a head-up display, a head-up display method, and a vehicle, the head-up display including: a heads-up display assembly configured to display an image at a projection location; the main control assembly is connected with the driving assembly and is configured to acquire vehicle information and analyze the vehicle information; generating a control instruction according to the analysis result; wherein the vehicle information includes: vehicle positioning information and vehicle attitude information, or driving road information and vehicle attitude information; and the driving assembly is connected with the head-up display assembly and is configured to adjust the head-up display assembly according to the control command, so that the projection position of the image displayed by the head-up display assembly is consistent with the relative height of the ground.
In the head-up display system in the prior art, all abnormal information acquired by a vehicle running at the current moment is projected and displayed, and too many irrelevant prompt messages are displayed at the same time, so that the attention of a driver is dispersed, or the judgment of the driver on the current road condition is interfered. The present invention is therefore directed to an electrically driven open ride which overcomes the above-mentioned disadvantages.
Chinese patent publication No. CN107683237A discloses a driving assistance method, and a driving assistance device, a driving control device, a vehicle, and a driving assistance program using the driving assistance method. The patent mainly realizes the image display function of the image information of the vehicle based on different moments, and the final object is actually the display process of the image of the vehicle, the process of predicting and displaying the next vehicle state according to the driving state and the surrounding state information, and the processes are not important reference information which directly influences the next operation behavior of the user for operating the walking substituting device. The invention determines the respective safety levels of a plurality of driving targets based on the driving data or the surrounding environment data, determines the driving targets capable of ensuring the personal safety of the driver to the maximum extent according to the safety levels to perform priority execution, and highlights the prompt information related to the driving targets, thereby avoiding the misoperation of busy hands and feet caused by that the driver receives excessive abnormal prompts suddenly in a short time. That is to say, the prompt messages are displayed sequentially according to the time sequence, and the essence of the invention is that a driving guidance strategy is provided for the driver, so that the driver can preferentially pay attention to the prompt messages displayed in front according to the prompt messages, further finish a plurality of driving targets step by step, and finally achieve the purpose of improving the personal safety of the driver to the maximum extent.

The front wind shield 10 may be disposed on the sleeve 2a, so as to block the wind coming from the front of the driver during the driving of the convertible device, thereby reducing the degree of the cold wind blowing to the legs of the driver. The rear bumper 11 can be mounted on the chassis 1 to reduce the degree of damage to the rear of the open ride caused by a collision.
Preferably, the function selection instrument panel 2c is further provided with a first shift lever 12 for controlling the forward movement of the open travel unit and a second shift lever 13 for controlling the backward movement of the open travel unit. For example, when the first lever 12 is pressed, the driver 5 can rotate clockwise, and when the second lever 13 is pressed, the driver can rotate counterclockwise. The first shifter lever 12 and the second shifter lever 13 can be respectively located on both sides of the function selection dial 2c, thereby enabling the left hand of the driver to be used for controlling the first shifter lever 12 and the right hand to be used for controlling the second shifter lever 13.
Preferably, at least one front lamp 14 may be provided on the function selection instrument panel 2 c. The headlight 14 can be electrically connected to the power supply unit 7. By providing the front lamp 14, the road surface in front of the driver can be illuminated, and the driver can drive at night conveniently. The function selection instrument panel 2c is also provided with a one-key starting function key 15 which can at least control the power-on and power-off of the driving part 5, so that the opening process of the open instead-of-walk device can be simplified, and the device is particularly suitable for the old.
Example 2
This embodiment is a further improvement of embodiment 1, and repeated contents are not described again.
Preferably, the convertible walker further comprises a head-up display 16. The head-up display 16 includes at least a processor 16a, a display panel 16b, a light source 16c, a first optical element 16d, and a second optical element 16 e. The processor 16a can be communicatively coupled to a vehicle control system or ECU unit of the convertible walker, and can read vehicle parameters such as speed, remaining battery power, etc. of the vehicle. The display panel 16b can be communicatively coupled to the processor 16a, and the driving parameters collected by the processor 16a can be transmitted to the display panel 16b for display. The light source 16c is coupled to the display panel 16b such that light generated by the light source can act as a backlight for the display panel 16b, thereby enabling display content on the display panel 16b to be projected onto the first optical element 16 d. The first optical element 16d can reflect the projection content received by it to the second optical element 16e, and finally, the projection content is projected again by reflection by the second optical element 16e onto, for example, a windshield mounted on a steering portion.
Preferably, the processor 16a is capable of collecting at least operating command data, driving data and ambient data of the open ride. The operating command data can be used to control the travel of the convertible walker, such that the convertible walker can perform different actions based on different operating command data. For example, the operation command data may be a speed control command input by the driver, by which the open ride is caused to travel at a set speed to enter a constant-speed cruise state. For example, the operation command data may be a driving path determined based on the navigation data, so that the convertible walker can drive according to the set driving path. It is understood that the convertible walker may be provided with a command input device for inputting operation command data. The command inputter may be a voice, image or touch based interactor. For example, the command input device may be a voice interactive device, which enables the driver to input his operation command data into the driving control system of the open-top walker by voice, and further enables the operation command data to be collected by the processor 16 a.
Preferably, the driving data are used for representing the driving state of the open-top ride instead of walking. For example, the driving data may include vehicle speed data, electric quantity data, tire pressure data, and the like of the convertible walker, and the driving state of the convertible walker can be determined by the driving data. The processor 16a can determine whether the convertible walker has a driving safety hazard according to the driving data. The processor 16a may have a memory for storing a standard threshold value of the driving data, and the processor 16a can compare the driving data received by the processor with the standard threshold value stored in the memory to determine whether a driving safety hazard exists. For example, a standard threshold of the vehicle speed may be set to 60Km/h, and when the actual driving speed is greater than the standard threshold, it may be preliminarily determined that the convertible walker has a driving safety hazard. Also, for example, the standard threshold value of the remaining capacity may be set to 5 Kw. When the actual residual electric quantity is smaller than the standard threshold value, the potential safety hazard of driving of the open instead-of-walk device can be preliminarily judged.
Preferably, the ambient environment data refers to environment data within a set distance around the convertible walker. The convertible walker can be provided with sensor components such as a radar and a 360-degree panoramic display, and the sensor components can be used for acquiring the surrounding environment data of the convertible walker. Ambient environment data can be used to evaluate the interrelationships between the convertible walker and other physical elements in the environment. The physical elements may include objects of the convertible walker that can affect the driving state of the convertible walker, such as pedestrians, vehicles, obstacles, traffic lights, etc., within a set distance of 200 meters of a square circle. For example, a sudden occurrence of a pedestrian in front of the convertible walker, or a sudden slowing of the vehicle in front of it, etc., may result in a change in the speed of the convertible walker. Obstacles that occur in front of an open ride can cause the path of travel of the open ride to change. The ambient environment data may include first data characterizing a real-time status of the solid element itself, and second data characterizing an interaction relationship between the solid element and the open walker. For example, the first data may comprise data of the entity element, such as a moving speed, a moving direction, etc., i.e. the physical state of the entity element may be determined by the first data. The second data may include spacing between the entity elements and the open ride, travel path conflicts, and the like. For example, the convertible walker runs on the rightmost lane of the expressway, and there may be other vehicles running into the expressway through ramps in front of the convertible walker, and the vehicle may first enter the rightmost lane of the expressway when entering the expressway, so that the vehicle collides with the running path of the convertible walker.
Preferably, the processor 16a may also determine the standard threshold of the driving data according to the ambient environment data. For example, the safe driving distance between the convertible walker and the vehicle in front of it may be set to 100 meters, and the processor 16a may be able to obtain the maximum driving speed of the convertible walker according to the relative speed of the convertible walker and the vehicle in front of it, and when the actual speed of the convertible walker is greater than the maximum driving speed, the distance between the convertible walker and the vehicle in front will gradually decrease, so that there is a risk that the safe driving distance will be less than 100 meters. For example, a specific implementation thereof may employ an adaptive cruise method equipped with an existing vehicle.
Preferably, the head-up display unit 16 is configured to:
s1: determining a plurality of driving targets and a plurality of prompt messages respectively corresponding to the plurality of driving targets based on at least one of the operation command data, the driving data and the surrounding environment data.
Specifically, for example, when the convertible walker is driven to approach an intersection where a left turn is required based on the navigation data, at least the following driving targets are generated: a first driving target that makes a lane change in advance to enter a left-turn lane determined based on the operation command data; determining a second driving target needing to be decelerated based on the driving data so as to avoid collision with a front vehicle, needing to pay attention to the electric quantity because of insufficient residual electric quantity, needing to stop and confirming the tire pressure and the like; the determination based on the surrounding environment data is, for example, a third traveling target such as avoidance of a left-rear incoming vehicle, avoidance of a front obstacle, deceleration to avoid overspeed, no lane change permitted on the current road, and the like. The first travel target, the second travel target, and the third travel target each generate different prompt information. For example, the first traveling target may cause a congestion on the road ahead, and may need to change lanes in advance. The second driving target can generate prompt information that the current electric quantity, the current tire pressure, the current speed per hour and the like are abnormal. The third traveling target can generate prompt information such as the distance to the front obstacle, the road speed limit condition, the violation lane change risk, the electronic eye condition, the rear vehicle coming condition and the like.
S2: the safety level of each of the plurality of traveling targets is determined based on the surrounding environment data, the traveling target with the highest safety level is selected as a first priority execution target, and the first prompt information related to the first priority execution target is displayed differently from the prompt information related to the other traveling targets, and/or the safety level of each of the plurality of traveling targets is determined based on the traveling data, the traveling target with the lowest safety level is selected as a second priority execution target, and the second prompt information related to the second priority execution target is displayed differently from the prompt information related to the other traveling targets, wherein the second prompt information displayed by the head-up display unit 16 has a higher priority than the first prompt information.
Specifically, the safety level of the driving target may be determined by the degree of influence of the risk involved in the driving data or the surrounding environment data on the life safety of the driver. For example, the heads-up display 16 may configure a security assessment algorithm. The safety evaluation algorithm can set a plurality of risk parameters which are related to the driving target and can influence the life safety of the driver, and the safety level of the driving target can be determined according to the detected number of the risk parameters. For example, when a traveling target needs a left turn and the front is an intersection, the risk parameters of the traveling target may be set to: whether the left rear side has the coming vehicle or not, the speed of the coming vehicle at the left rear side, whether the distance between the left rear side and the coming vehicle at the left rear side meets the lane change requirement or not and the like. When it is detected that the left side does not have an incoming car, the level of the travel target may be set to a first level indicating safety. When it is detected that there is an incoming vehicle behind, the incoming vehicle is too fast, and the distance to the incoming vehicle is too small to meet the lane change requirement, the level of the travel target may be set to a second level indicating that it is not very safe. It can be understood that different specific gravity values can be set for different risk parameters, and then a plurality of safety levels can be obtained.
Preferably, the driving data are used to characterize the driving state of the convertible walker. The driving data can comprise vehicle speed data, electric quantity data, tire pressure data and the like of the convertible travel substituting device. Namely, whether the convertible walk-substituting device per se is abnormal or not can be determined through the driving data. When the convertible travel replacement device itself is abnormal, the severity level thereof is high, which may cause the convertible travel replacement device to be broken, and thus, traffic accidents such as rear-end collisions may be easily caused on, for example, a highway, and therefore, the second prompt information related to the second priority execution target having the lowest safety level determined based on the traveling data should be preferentially displayed on the head-up display portion 16. For example, the priority may be expressed in that the second guidance information is displayed with the highest brightness, the display time is the first, the display color is the most conspicuous, and the like.
Preferably, the ambient environment data can be used to evaluate the interrelationship between the convertible walker and other physical elements in the environment. The respective safety level of the several driving objectives is determined based on the surrounding environment data, which can be used to evaluate the degree of conflict between the work performed by the open walker and the actions between the physical elements of its surroundings. I.e. whether the actions of the physical elements in the surroundings pose a threat to the life safety of the driver. For example, when a traveling target needs a left turn and the front is an intersection, the risk parameters of the traveling target may be set to: whether the left rear side has the coming vehicle or not, the speed of the coming vehicle at the left rear side, whether the distance between the left rear side and the coming vehicle at the left rear side meets the lane change requirement or not and the like. When it is detected that the left side does not have an incoming car, the level of the travel target may be set to a first level indicating safety. When it is detected that there is an incoming vehicle behind, the incoming vehicle is too fast, and the distance to the incoming vehicle is too small to meet the lane change requirement, the level of the travel target may be set to a second level indicating that it is not very safe. In this case, it is necessary to take the traveling target with the highest safety level as the priority execution target to improve the personal safety of the driver to the maximum extent.
Preferably, the first prompt message associated with the first priority execution target and the second prompt message associated with the second priority execution target can be determined by whether they pose a threat to the personal safety of the driver. For example, when abnormal information such as an obstacle is present in the convertible riding device during driving, the lane change is not permitted on the current road, the electronic eye is present at the current position, and the vehicle is coming to the rear left, the head-up display 16 displays the abnormal information, and the obstacle is present in the front and the vehicle is coming to the left, which are the most serious factors affecting the life safety of the driver, and thus the abnormal information can be highlighted as the first prompt information or the second prompt information. Meanwhile, abnormal information which does not allow lane changing, has electronic eyes at the current position and the like and is not enough to threaten the life safety of the driver is not displayed or is weakly displayed, so that the excessive distraction of the driver is avoided, and the attention of the driver can focus on how to avoid obstacles and avoid a rear coming vehicle.
S3: and sequentially displaying the prompt information corresponding to the plurality of driving targets according to a time sequence mode.
Specifically, when the safety level of each of the plurality of travel targets is determined based on the surrounding environment data, the prompt information corresponding to the travel target having the higher safety level is displayed earlier. Alternatively, when the safety level of each of the plurality of traveling targets is determined based on the traveling data, the presentation information corresponding to the traveling target having the lower safety level is displayed earlier, and the presentation time of the presentation information corresponding to the traveling target having the lowest safety level determined based on the traveling data may be earlier than the presentation time of the presentation information corresponding to the traveling target having the highest safety level determined based on the ambient environment data.
Preferably, the prompt information corresponding to each of the plurality of driving targets may be displayed in a differentiated manner. The display areas different from each other for different driving targets can display the related prompt information in a manner different from each other according to the safety level of the driving target. For example, several display areas may be provided on the display panel 16b according to the number of the driving targets, and each display area is used for displaying prompt information corresponding to different driving targets. Different display areas can have different brightness, different colors, different flashing modes and the like so that different prompt messages can be displayed in a distinguishing way. The lower the safety level determined based on the traveling data, the traveling target can have higher brightness, brighter color, or faster blinking frequency. The travel target with the highest security level determined based on the surrounding environment data can have higher brightness, brighter color, or faster blinking frequency.
Through the mode, the following technical effects can be at least achieved: one, head-up display system among the prior art can all carry out projection display with all the information of suspected abnormality that the vehicle got under driving under the current moment, has too much and irrelevant suggestion information to show simultaneously, and then leads to driver's distraction, or can disturb driver's the judgement to current road conditions. For example, when a driver drives a vehicle to turn left, the head-up display system may project and display prompt information that is insufficient in power, does not pose a safety hazard to the vehicle turning left, such as the current speed per hour, and may further interfere with the driver. The invention determines the respective safety levels of a plurality of driving targets based on the driving data or the surrounding environment data, determines the driving targets capable of ensuring the personal safety of the driver to the maximum extent according to the safety levels to perform priority execution, and highlights the prompt information related to the driving targets, thereby avoiding the phenomenon that the driver suddenly receives excessive abnormal prompts in a short time to cause busy hands and feet. The invention is characterized in that a driving guidance strategy is provided for a driver, so that the driver can preferentially pay attention to the prompt information displayed in front according to the prompt information, further finish a plurality of driving targets step by step, and finally achieve the aim of improving the personal safety of the driver to the maximum extent.
It should be noted that the above-mentioned embodiments are exemplary, and that those skilled in the art, having benefit of the present disclosure, may devise various arrangements that are within the scope of the present disclosure and that fall within the scope of the invention. It should be understood by those skilled in the art that the present specification and figures are illustrative only and are not limiting upon the claims. The scope of the invention is defined by the claims and their equivalents.
