[0025] Specifically, Figure 1 A schematic diagram of the structure of an ECAS control system for an unmanned vehicle provided in an embodiment of the present application.

[0026] like Figure 1 As shown, the ECAS control system 10 of the unmanned vehicle includes: a vehicle body lifting component 100 , a state detection component 200 and a control component 300 .

[0027] Specifically, the vehicle body lifting assembly 100 is used to control the raising or lowering of the vehicle body of the driverless vehicle.

[0028] During the actual implementation process, the body lifting component 100 can control the raising or lowering of the body of the unmanned vehicle to meet the needs of the safety officer or the passengers in the vehicle. The body lifting component 100 may include a solenoid valve, a height sensor and an air cylinder. The solenoid valve is used to increase, decrease and maintain the air pressure of the airbag to realize the lifting and side kneeling of the body. The height sensor detects the height of the body and generates a height signal. The air cylinder is used to provide an air source to the airbag.

[0029] It should be noted that the connection method of the solenoid valve, height sensor and air tank will be explained in detail below.

[0030] The state detection component 200 is used to detect at least one state information of the unmanned vehicle.

[0031] As a possible implementation method, the state detection component 200 can be used to detect and perceive the state information of the unmanned vehicle, wherein the state information may include the vehicle's operating conditions, actual vehicle speed, and actual door switch status, etc., so as to adjust the vehicle height based on the state information, thereby increasing the intelligence level of the vehicle and improving the driving experience of passengers or safety officers.

[0032] Optionally, in one embodiment of the present application, the state detection component 200 includes: a vehicle condition detection subcomponent, a vehicle speed detection subcomponent and a vehicle door detection subcomponent.

[0033] Among them, the vehicle condition detection subcomponent is used to detect the operating condition of the unmanned vehicle.

[0034] The vehicle speed detection subcomponent is used to detect the actual speed of the driverless vehicle.

[0035] The door detection subassembly is used to detect the actual open / closed state of at least one door among all the doors of the driverless vehicle.

[0036] In some embodiments, the state detection component 200 may include a vehicle condition detection subcomponent, a vehicle speed detection subcomponent, and a vehicle door detection subcomponent.

[0037] The vehicle condition detection subassembly may include a camera and / or a radar, wherein the camera is used to photograph the road on which the unmanned vehicle is traveling, and the radar is used to detect the road on which the unmanned vehicle is traveling. The operating condition information includes the height information of obstacles on the road on which the unmanned vehicle is traveling.

[0038] The vehicle speed detection subcomponent can detect the actual speed of the unmanned vehicle, thereby correlating the actual speed with the vehicle body height, so as to subsequently adjust the vehicle body height according to the actual speed to maintain vehicle body stability.

[0039] The door detection subcomponent can reuse the door detection configured in the vehicle to detect the door switch status of the unmanned vehicle, thereby associating the door switch status with the vehicle body height so that the vehicle body height can be adjusted to the appropriate position when passengers or safety officers get on and off the vehicle.

[0040] The control component 300 is used to generate a vehicle body control strategy under different working conditions according to at least one state information, so as to control the vehicle body lifting component 100 to adjust the vehicle body height of the unmanned vehicle based on the vehicle body control strategy.

[0041] During the actual execution process, the control component 300 can generate a body control strategy under different working conditions based on at least one state information detected, that is, according to different working conditions, it can generate a strategy for controlling the lifting or kneeling of the body, so as to control the body lifting component 100 to adjust the body height of the unmanned vehicle based on the body control strategy, so that the vehicle can meet the requirements of driving safety, vehicle passengers or safety officers for body height under different working conditions.

[0042] It should be noted that the body control strategies under different working conditions will be explained in detail below.

[0043] Optionally, in one embodiment of the present application, the control component 300 includes: an ECAS controller and a vehicle controller.

[0044] The ECAS controller is used to respond to the body control strategy to control the body lifting assembly 100 to adjust the body height of the unmanned vehicle based on the body control strategy.

[0045] The vehicle controller is used to analyze at least one state information and determine the current operating condition of the unmanned vehicle based on the analysis result, so as to generate a body control strategy based on the current operating condition.

[0046] Furthermore, the control component 300 may include an ECAS controller and a vehicle controller.

[0047] Among them, the vehicle controller can generate a corresponding body control strategy based on the operating condition information, vehicle speed and door switch status of the unmanned vehicle detected by the status detection component 200.

[0048] The ECAS controller can respond to the body control strategy generated by the vehicle controller and generate corresponding control instructions, thereby controlling the body lifting component 100 to adjust the body height of the unmanned vehicle.

[0049] In some embodiments, the solenoid valve of the vehicle body lifting assembly 100 can be connected to the height sensor through a wiring harness, the height sensor can be installed on the vehicle body, and both the solenoid valve and the height sensor are connected to the ECAS controller, and the air tank is connected to the solenoid valve through a pipe bundle.

[0050] Optionally, in one embodiment of the present application, the control component 300 is specifically used to determine that the current operating condition of the unmanned vehicle is a door-opening condition when the actual switch state is an open state, and generate a first body control instruction based on the door-opening condition to lower the body on one side of at least one door in the unmanned vehicle to a first target height.

[0051] Here, the body control strategy under the door opening condition is explained.

[0052] When the door detection subassembly detects that the door is in an open state, the control component 300 can determine that the current operating condition of the unmanned vehicle is an open door condition, and transmit the body control strategy to the ECAS controller. The ECAS controller controls the body lifting height performed by the body lifting component 100, so that the detected door switch state is associated with the body height.

[0053] Specifically, the body lifting component 100 can lower the body of the unmanned vehicle on the side where the door is opened to a first target height, complete the side kneeling of the vehicle, and facilitate passengers inside and outside the vehicle, such as children, the elderly, etc., to get on and off the vehicle, wherein the first target height can be set accordingly by those skilled in the art according to actual conditions, and no specific restrictions are made here. Optionally, in one embodiment of the present application, the control component 300 is specifically used to determine that the current operating condition of the unmanned vehicle is an obstacle avoidance condition when the operating condition is a road obstacle condition, and generate a second body control instruction based on the obstacle avoidance condition to raise the body of the unmanned vehicle to a second target height.

[0054] Here, the vehicle body control strategy under road obstacle conditions is explained.

[0055] When the vehicle condition detection subassembly can use a camera to shoot the road on which the unmanned vehicle is traveling, and use a radar to detect the road, the raised height information of obstacles on the road on which the unmanned vehicle is traveling can be obtained, and the vehicle controller generates a corresponding body control strategy based on the raised height information. For example, when it is detected that the raised height of the obstacle is higher than the current chassis height of the unmanned vehicle, the unmanned vehicle needs to rise to the second target height, and the ECAS controller sends a rise command to the body lifting assembly 100, wherein the second target height can be set accordingly by those skilled in the art, and no specific limitation is made here.

[0056] Optionally, in one embodiment of the present application, the control component 300 is specifically used to determine that the current operating condition of the unmanned vehicle is an overspeeding condition when the actual vehicle speed is greater than a preset speed threshold, and generate a third body control instruction based on the overspeeding condition to lower the body of the unmanned vehicle to a third target height.

[0057] Here, the vehicle body control strategy under overspeed conditions is explained.

[0058] When the vehicle speed detection subcomponent detects that the actual vehicle speed is greater than a preset speed threshold, the control component 300 can determine that the vehicle is in an overspeeding condition, and the vehicle controller generates a corresponding body control strategy and transmits it to the ECAS controller. The ECAS controller sends a control instruction to the body lifting component 100 to control the vehicle's body lifting height, so that the detected vehicle speed is associated with the body height.

[0059] The body control strategy can be used to instruct the unmanned vehicle to descend from the current body height to a third target height, wherein the preset speed threshold and the third target height can be set accordingly by technicians in this field according to actual conditions, and no specific restrictions are made here.

[0060] Optionally, in one embodiment of the present application, the ECAS control system 10 of the unmanned vehicle further includes: a charging acquisition component.

[0061] Among them, the charging acquisition component is used to obtain the actual charging status of the unmanned vehicle.

[0062] In some embodiments, the system 10 of the embodiment of the present application may also include a charging acquisition component to obtain the actual charging status of the unmanned vehicle. For example, the charging acquisition component can detect whether the wireless charging of the vehicle is turned on, thereby determining the actual charging status of the unmanned vehicle based on the detection results, including charging preparation status, charging status, uncharged status, etc.

[0063] Optionally, in one embodiment of the present application, the control component 300 is specifically used to determine that the current operating condition of the unmanned vehicle is a charging preparation condition when the actual charging state is a waiting-to-charge state, and generate a fourth body control instruction based on the charging preparation condition to lower the body of the unmanned vehicle to a fourth target height.

[0064] Here, the body control strategy under charging preparation conditions is explained.

[0065] For example, after the charging acquisition component detects that the wireless charging of the unmanned vehicle is turned on, the vehicle controller generates a corresponding body control strategy based on the charging information and transmits the body control strategy to the ECAS controller. The ECAS controller sends a control instruction to control the body lifting component 100, so that the body lifting component 100 adjusts the body to a fourth target height to align with the charging port, wherein the fourth target height can be set accordingly by a technician in this field and is not specifically limited here.

[0066] Combination Figure 2 As shown, the working principle of the ECAS control system 10 of the unmanned vehicle according to the embodiment of the present application is described in detail by taking an embodiment as an example.

[0067] like Figure 2 As shown, the ECAS control system 10 of the unmanned vehicle in the embodiment of the present application includes: a body lifting component 100, a state detection component 200, a vehicle condition detection subcomponent 201, a vehicle speed detection subcomponent 202, a door detection subcomponent 203, a charging acquisition component 204, a control component 300, an ECAS controller 301 and a vehicle controller 302.

[0068] Among them, the body lifting component 100 can control the raising or lowering of the body of the unmanned vehicle to meet the needs of the safety officer or the passengers in the vehicle. Among them, the body lifting component 100 may include a solenoid valve, a height sensor and an air cylinder. The solenoid valve is used to increase, reduce and maintain the air pressure of the airbag to realize the lifting and side kneeling of the body. The height sensor detects the height of the body and generates a height signal. The air cylinder is used to provide an air source to the airbag.

[0069] The state detection component 200 can be used to detect and sense the state information of the driverless vehicle. The state detection component 200 can include: a vehicle condition detection subcomponent 201, a vehicle speed detection subcomponent 202 and a door detection subcomponent 203.

[0070] The vehicle condition detection subassembly 201 may include a camera and / or a radar, wherein the camera is used to photograph the road on which the unmanned vehicle is traveling, and the radar is used to detect the road on which the unmanned vehicle is traveling. The operating condition information includes the height information of obstacles on the road on which the unmanned vehicle is traveling.

[0071] The vehicle speed detection subassembly 202 can detect the actual vehicle speed of the driverless vehicle, thereby associating the actual vehicle speed with the vehicle body height, so as to subsequently adjust the vehicle body height according to the actual vehicle speed to maintain vehicle body stability.

[0072] The door detection subcomponent 203 can reuse the door detection configured by the vehicle to detect the door switch status of the unmanned vehicle, thereby associating the door switch status with the vehicle body height so that the vehicle body height can be adjusted to a suitable position when passengers or safety officers get on and off the vehicle.

[0073] The charging acquisition component 204 can detect whether the wireless charging of the vehicle is turned on, and thus determine the actual charging state of the unmanned vehicle according to the detection result, including charging preparation state, charging state, uncharged state, etc.

[0074] The control component 300 can generate a body control strategy under different working conditions based on at least one state information detected, that is, generate a strategy for controlling the lifting or kneeling of the body according to different working conditions, so as to control the body lifting component 100 to adjust the body height of the unmanned vehicle based on the body control strategy, so that the vehicle can meet the requirements of driving safety, vehicle passengers or safety officers for body height under different working conditions.

[0075] The control component 300 may include an ECAS controller 301 and a vehicle controller 302 .

[0076] The vehicle controller 302 may generate a corresponding vehicle body control strategy based on the operating condition information, vehicle speed, and door switch status of the unmanned vehicle detected by the status detection component 200 .

[0077] The ECAS controller 301 can respond to the body control strategy generated by the vehicle controller 302 and generate corresponding control instructions, thereby controlling the body lifting component 100 to adjust the body height of the unmanned vehicle. The solenoid valve of the body lifting component 100 can be connected to the height sensor through a wiring harness, the height sensor can be installed on the vehicle body, and the solenoid valve and the height sensor are both connected to the ECAS controller, and the air tank is connected to the solenoid valve through a pipe bundle.

[0078] In the actual implementation process, the embodiments of the present application may include a variety of working conditions:

[0079] 1. When the door detection subcomponent 203 detects that the door is in an open state, the control component 300 can determine that the current operating condition of the unmanned vehicle is an open door condition, and transmit the body control strategy to the ECAS controller 301. The ECAS controller 301 controls the body lifting height performed by the body lifting component 100, so that the detected door switch state is associated with the body height.

[0080] Specifically, the body lifting assembly 100 can lower the body of the unmanned vehicle on the side where the door is opened to a first target height, completing the side kneeling of the vehicle, making it easier for passengers inside and outside the vehicle, such as children and the elderly, to get on and off the vehicle. The first target height can be set accordingly by technicians in this field according to actual conditions, and no specific restrictions are made here.

[0081] Second, when the vehicle condition detection subassembly 201 can use a camera to shoot the road on which the unmanned vehicle is traveling, and use a radar to detect the road, and obtain the raised height information of obstacles on the road on which the unmanned vehicle is traveling, the vehicle controller 302 generates a corresponding body control strategy based on the raised height information. For example, when it is detected that the raised height of the obstacle is higher than the current chassis height of the unmanned vehicle, the unmanned vehicle needs to rise to the second target height, and the ECAS controller 301 sends a rise command to the body lifting assembly 100, wherein the second target height can be set accordingly by those skilled in the art, and no specific limitation is made here.

[0082] 3. When the vehicle speed detection subcomponent 202 detects that the actual vehicle speed is greater than the preset speed threshold, the control component 300 can determine that the vehicle is in an overspeed condition, and the vehicle controller 302 generates a corresponding body control strategy and transmits it to the ECAS controller 301. The ECAS controller 301 sends a control instruction to the body lifting component 100 to control the vehicle's body lifting height, so that the detected vehicle speed is associated with the body height.

[0083] The body control strategy can be used to instruct the unmanned vehicle to descend from the current body height to a third target height, wherein the preset speed threshold and the third target height can be set accordingly by technicians in this field according to actual conditions, and no specific restrictions are made here.

[0084] 4. After the wireless charging of the unmanned vehicle detected by the charging acquisition component 204 is turned on, the vehicle controller 302 generates a corresponding body control strategy based on the charging information, and transmits the body control strategy to the ECAS controller 301. The ECAS controller 301 sends a control instruction to control the body lifting component 100, so that the body lifting component 100 adjusts the body to a fourth target height and aligns it with the charging port. The fourth target height can be set accordingly by those skilled in the art and is not specifically limited here.

[0085] In summary, the embodiment of the present application can generate a body control strategy through the vehicle controller 302, and the ECAS controller 301 determines the height value required for the vehicle to adjust from the current body height to the target body height according to the body control strategy, and then controls the body lifting component 100 to adjust the body height to the target height value to realize vehicle lifting or side kneeling. The system 10 provided in the embodiment of the present application does not need to operate the ECAS switch to generate a signal. It only needs the vehicle controller 302 of the vehicle or other upper computer that is functionally interoperable with the vehicle controller 302 to send a control instruction to realize vehicle lifting. Without the participation of passengers or safety officers, the intelligent automatic lifting of unmanned vehicles can be realized. At the same time, since the ECAS switch is cancelled, the structural complexity of the vehicle can also be reduced. At the same time, the system 10 proposed in the embodiment of the present application can be used to accurately execute the body control strategy issued by the vehicle controller 302, and effectively realize real-time active control of the body height.

[0086] According to the ECAS control system of the unmanned vehicle proposed in the embodiment of the present application, the control component can generate the body control strategy under different working conditions based on the state information detected by the state detection component, so as to control the body lifting component according to the body control strategy to adjust the body height of the unmanned vehicle, without the need for the driver or the safety officer of the unmanned vehicle to manually adjust the body height, thereby increasing the intelligence level of the vehicle and improving the driving experience of passengers or safety officers. Thus, the technical problem of the related technology that the adjustment of the body height needs to be achieved by manual operation of the driver or the safety officer, and adaptive adjustment cannot be achieved, which is not conducive to improving the driving experience of passengers or safety officers and has a low intelligence level is solved.

[0087] Next, the ECAS control method for an unmanned vehicle proposed in accordance with an embodiment of the present application will be described with reference to the accompanying drawings.

[0088] Figure 3Flow chart of the ECAS control method of the unmanned vehicle according to an embodiment of the present application.

[0089] like Figure 3 As shown, the ECAS control method of the unmanned vehicle includes the following steps:

[0090] In step S301, at least one state information of the unmanned vehicle is detected.

[0091] In step S302, a vehicle body control strategy under different working conditions is generated according to at least one state information.

[0092] In step S303, the body lifting component is controlled to adjust the body height of the unmanned vehicle based on the body control strategy.

[0093] It should be noted that the above explanation of the embodiment of the ECAS control device for an unmanned vehicle is also applicable to the ECAS control method for an unmanned vehicle in this embodiment, and will not be repeated here.

[0094] According to the ECAS control method for unmanned vehicles proposed in the embodiment of the present application, the control component can generate a body control strategy under different working conditions based on the state information detected by the state detection component, thereby controlling the body lifting component according to the body control strategy to adjust the body height of the unmanned vehicle, without the need for the driver or the safety officer of the unmanned vehicle to manually adjust the body height, thereby increasing the intelligence level of the vehicle and improving the driving experience of passengers or safety officers. As a result, the technical problem of the related art that the body height adjustment needs to be achieved through manual operation by the driver or the safety officer, and adaptive adjustment cannot be achieved, which is not conducive to improving the driving experience of passengers or safety officers and has a low intelligence level is solved.
