[0002] During the manufacturing process of a vehicle, the performance of the chassis needs to be tested, such as testing the braking performance of the chassis braking system when the vehicle hits an obstacle while driving at high speed. Chassis testing is usually carried out during the development stage, when the chassis has not yet been installed with a perception kit, industrial computer kit, etc., so an external simulation device is usually built to simulate the vehicle's driving conditions, and the chassis is placed in the external simulation device for testing.

[0043] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0044] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0045] Figure 1 A schematic diagram of the vehicle chassis test scenario provided for this application, such as Figure 1 As shown, the specific application scenario of the present application provides a real test track for vehicle chassis testing, and the test track provides sufficient acceleration distance, driving distance after stabilizing the vehicle speed, and braking distance. The vehicle to be tested 101 can travel along a predetermined route or a preset track in the test regulations to meet the conditions of various test items. However, in this test scenario, the difficulty lies in that the vehicle chassis test is usually carried out in the development stage, and the perception kit, industrial computer kit, etc. have not been installed on the chassis. Manual operation of the remote control is required to control the vehicle driving, and the remote control range of the remote control 103 is limited. It is difficult to control the vehicle to reach the test speed within the limited remote control range, such as controlling the vehicle to be tested to accelerate to 70km / h. And when the vehicle to be tested is far away from the operator, the operator cannot see the road conditions ahead clearly, which makes the test process extremely dangerous. Therefore, it is difficult for the vehicle chassis to be tested. Figure 1 Test in real test scenarios in examples.

[0046] The vehicle chassis test method provided by the present application configures multiple remote control sites between the test start position and the target position of the test scene, and each remote control site is correspondingly configured with at least one remote control 103, and the distance between the remote controls 103 is less than or equal to the remote control range of the remote control 103. Correspondingly, multiple signal receiving boxes 102 are installed on the vehicle to be tested 101, and each signal receiving box 102 is paired with a remote control 103. The remote control 103 relays the control of the vehicle to be tested 102, and the vehicle to be tested 102 accurately switches the remote control signal to control the vehicle to be tested 102 to travel along a preset trajectory, meet the conditions required by the test project, and enable the vehicle chassis test to be carried out in a real test scene, thereby improving the test accuracy.

[0047] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0048] Figure 2 A schematic diagram of a vehicle chassis testing method provided in an embodiment of the present application Figure 1 ,like Figure 2 As shown, the method includes:

[0049] S201, determining a target control instruction from a remote control signal received by a signal receiving box;

[0050] like Figure 1 In the scenario shown, the vehicle to be tested is a vehicle with a chassis installed. The vehicle to be tested is equipped with multiple signal receiving boxes, each of which is paired with at least one remote control. During the test, operators are located at different positions on the test track and operate the remote control to control the vehicle to be tested. When the vehicle to be tested is driving, when the signal receiving box is within the remote control range of the paired remote control, it can receive the remote control signal sent by the paired remote control, and the vehicle to be tested can obtain the remote control signal of the remote control through the signal receiving box.

[0051] For example, Figure 1 As shown, when the vehicle to be tested is located near point A (for example, within the remote control range of the remote control at point A), the signal receiving box paired with the remote control at point A can receive the remote control signal sent by the remote control. When the vehicle to be tested is controlled by the remote control and is driving near point B (for example, within the remote control range of the remote control at point B), the signal receiving box paired with the remote control at point B can receive the remote control signal sent by the remote control, and the vehicle to be tested can be remotely controlled by the remote control at point B, realizing the switching from the remote control at point A to the remote control at point B, and switching in sequence, and remotely controlling the vehicle to be tested through remote controls at different locations.

[0052] In this step, after receiving the remote control signal, the signal receiving box transmits the remote control signal to the processor of the vehicle to be tested, and the processor of the vehicle to be tested determines the target control instruction according to the remote control signal.

[0053] As an optional implementation, the cooperation of the operator can ensure that only one signal receiving box always receives the remote control signal, and the processor determines the target control instruction according to the remote control signal. For example, the operator at point A controls the remote control (for example, the throttle is at the maximum gear) to control the vehicle to be tested. When the vehicle to be tested approaches point B, the operator at point A turns off the remote control or reduces the signal of the remote control, and the operator at point B controls the remote control (the throttle is at the maximum gear) to control the vehicle to be tested. In this way, the vehicle to be tested receives the remote control signal at point B, and the remote control signal at point A is disconnected, so the vehicle to be tested is controlled by the remote control at point B, realizing non-contact remote control switching.

[0054] As an optional implementation, the operator cooperates to control the vehicle to be tested in a way that only one signal receiving box always receives the remote control signal. This is difficult to achieve. Therefore, the test vehicle is combined with the test vehicle's choice of remote control signal to achieve the remote control signal that can always respond to the remote control. The specific implementation method can refer to the following Figure 3 Example.

[0055] S202: Control the vehicle to be tested according to the target control instruction so that the driving condition of the vehicle to be tested reaches the target condition required for the chassis test.

[0056] In this step, the target control instruction refers to the control instruction to which the vehicle to be tested finally responds, such as an acceleration control instruction, a braking control instruction or a steering control instruction, etc. The vehicle to be tested responds to the target control instruction to realize control of the vehicle to be tested in the test scenario.

[0057] In this step, the target working condition refers to the working condition required by the vehicle to be tested in the test items, for example, in the test items such as high-speed control of the test vehicle, the degree of damage caused by collision with obstacles at high speed, and braking distance, the target working condition requires the vehicle to be tested to be controlled to travel to the target speed (for example, 70km / h). Based on the difficulty of controlling the vehicle to be tested to travel to the target speed within the remote control range of a remote controller, this embodiment arranges multiple remote controllers and combines the remote controller switching control to increase the remote control range of the vehicle to be tested, thereby controlling the control distance of the vehicle to be tested, so that the vehicle to be tested can reach the required target speed to complete the chassis test.

[0058] Taking the test item of calculating the braking distance at a speed of 70 km / h when the vehicle hits an obstacle and triggers the emergency mode as an example, the specific process of chassis testing is explained:

[0059] 1. First, modify the controller parameters of the vehicle to be tested, calibrate the maximum speed of the vehicle to be tested, for example, modify it to 70km / h, modify the upper limit of the maximum speed in the remote control mode, for example, to 70km / h, and modify the maximum brake pressure in the emergency mode, for example, to 60bar. If there are other test items, only the upper limit value needs to be modified.

[0060] 2. During the calibration test, the zero point of each remote controller that needs to be involved in the control (that is, in remote control mode, when the remote controller does not move any control lever, the vehicle will not perform any action).

[0061] 3. Add weights to the vehicle to be tested to meet the full load mass requirements in the test regulations.

[0062] 4. The first operator carries remote controller No. 1, stands at the starting point, controls the vehicle to start and accelerates, and moves the acceleration control lever to the maximum position (each operator moves the corresponding action lever to the maximum value to ensure that the control signal sent by the remote controller in each operator's hand is consistent), while keeping the vehicle to be tested moving along the center line of the road.

[0063] 5. The second operator carries remote controller No. 2 and stands within the effective control range of remote controller No. 1 and near the range boundary.

[0064] 6. When the vehicle to be tested approaches the second operator, control the No. 2 remote controller to intervene. If you see the vehicle flashing, it means that the control has been intervened. Move the acceleration control lever to the maximum position and keep the vehicle moving along the center line of the road.

[0065] 7. The third operator will continue in this way until the vehicle speed remains stable and no longer increases, or the back-end network platform sees that the vehicle speed is maintained at 70km / h, then the test vehicle will be controlled to hit the preset obstacle.

[0066] 8. Record the distance from the obstacle to the vehicle's fully automatic stop, and record it as the braking distance of the vehicle at this mass, 70 km / h speed, and 60 bar braking pressure to complete the test.

[0067] The embodiment of the present application is applied in a vehicle chassis test scenario, and the driving condition of the vehicle to be tested is controlled to achieve the target condition required for the chassis test, so that the vehicle chassis is subjected to a collision test under the target condition; multiple signal receiving boxes are installed on the vehicle to be tested, and each signal receiving box is paired with a remote control, so that the vehicle to be tested can be controlled by multiple remote controls; multiple remote controls are arranged at different positions, and during the driving process of the vehicle to be tested, the distance between the previous signal receiving box and the paired remote control gradually increases, and the previous signal receiving box cannot receive the remote control signal of the remote control, while the distance between the next signal receiving box and the paired remote control gradually decreases, and the next signal receiving box starts to receive the remote control signal of the paired remote control, and the vehicle to be tested can always determine the target control instruction from the remote control signal received by at least one signal receiving box; then the vehicle to be tested is controlled according to the target control instruction; that is, the vehicle to be tested is controlled to drive in a real test scenario by relay control, the driving distance of the vehicle to be tested is increased, the requirements of the vehicle acceleration distance and the vehicle speed stable driving distance are met, and the chassis test is completed in the real test scenario.

[0068] Figure 3 A schematic flow chart of a vehicle chassis testing method provided in another embodiment of the present application is shown as follows: Figure 3 As shown, in this embodiment Figure 2 Based on the embodiment, a vehicle chassis testing method is described in detail, and the method includes:

[0069] S301, determining a target remote controller whose distance to the vehicle to be tested tends to be reduced according to the remote control signal received by the signal receiving box;

[0070] There are multiple signal receiving boxes installed on the vehicle to be tested, and all of them are connected to the processor of the vehicle to be tested. After receiving the remote control signal, the signal receiving boxes transmit the remote control signal to the processor. Since the distance between the remote controllers is less than or equal to the remote control distance, there is a situation where two remote control signals are received. Although under the cooperative control of the operator, one signal receiving box can receive the remote control signal at the same time to avoid multiple remote control signals being transmitted to the processor at the same time, the operator's cooperative control method has certain coordination difficulties and high requirements for the operator.

[0071] In this embodiment, multiple signal receiving boxes are allowed to receive remote control signals at the same time. By controlling the vehicle to be tested to only respond to the remote control signal sent by one of the remote controllers, the problem of multiple remote control signals simultaneously controlling the vehicle to be tested and affecting the driving safety of the vehicle to be tested is solved.

[0072] In this step, when at least two signal receiving boxes receive remote control signals, a target remote control whose distance from the vehicle to be tested tends to decrease is determined from the at least two remote control signals. The distance from the vehicle to be tested tends to decrease means that during the driving of the vehicle, the distance between the remote control at each remote control station and the vehicle to be tested gradually decreases. For example, Figure 1 , the vehicle to be tested drives towards the position corresponding to point A, gradually approaches point A, and the distance from point A decreases. Then the remote controller corresponding to point A is the target remote controller whose distance from the vehicle to be tested tends to decrease. For another example, please refer to Figure 4 ,If the vehicle to be tested travels from point A to point B, gradually approaches point B, and the distance from point B decreases, then the remote controller corresponding to point B is the target remote controller whose distance from the vehicle to be tested tends to decrease.

[0073] Optionally, the method for determining the target remote controller that is closest to the vehicle to be tested includes but is not limited to the following implementations:

[0074] As an optional implementation, determining a target remote controller whose distance from the vehicle to be tested tends to decrease according to the remote control signal received by the signal receiving box includes:

[0075] A1: Determine the signal frequency of the remote control sending the remote control signal according to the remote control signal received by the signal receiving box;

[0076] It should be noted that when the remote controller sends a remote control signal, it is sent at a certain signal frequency. In this embodiment, the signal frequency of each remote controller can be set to be different. Then, after the signal receiving box receives the remote control signal sent by the corresponding remote controller, the processor can analyze the corresponding signal frequency according to the remote control signal, and then determine the remote controller that sent the remote control signal.

[0077] A2: Determine the target remote controller whose distance to the vehicle to be tested tends to decrease according to the signal frequency, wherein the remote controller corresponding to the maximum signal frequency is the target remote controller, or the remote controller corresponding to the minimum signal frequency is the target remote controller.

[0078] In this embodiment, each remote controller can be distributed on the test road in the order of signal frequency from small to large, that is, from the starting position to the target position of the test road, each remote controller is distributed in the order of signal frequency from small to large. When at least two signal receiving boxes receive the signal frequency, it means that the vehicle to be tested is traveling from the previous remote control station to the next remote control station and has entered the remote control range of the next remote control station. The distance between the remote controller of the previous remote control station and the vehicle to be tested tends to increase, and the distance between the remote controller of the next remote control station and the vehicle to be tested tends to decrease. It is necessary to switch to the next remote controller for remote control, and the signal frequency of the remote controller of the next remote control station is greater than the signal frequency of the remote controller of the previous remote control station. Therefore, the remote controller at the next remote control station corresponding to the maximum signal frequency is used as the target remote controller to realize remote control switching.

[0079] Alternatively, the remote controllers may be distributed on the test road in the order of signal frequencies from large to small, that is, from the starting position of the test road to the target position, the remote controllers may be distributed in the order of signal frequencies from large to small. In the example of distributing the remote controllers in the order of signal frequencies from large to small, the remote controller with the smallest signal is determined to be the target remote controller. The specific principle is the same as the above example, and will not be repeated here.

[0080] In this embodiment, the target remote control is determined by the signal frequency of the remote control. During the remote control switching process, the remote control to be used to control the vehicle to be tested can be automatically and accurately identified without the need for operator cooperation, thereby increasing automation and reducing operator requirements.

[0081] As another optional implementation, determining a target remote controller whose distance from the vehicle to be tested tends to decrease according to the remote control signal received by the signal receiving box includes:

[0082] B1: According to the remote control signal received by the signal receiving box, determine the ID of the remote control sending the remote control signal;

[0083] In this step, each remote controller is configured with a corresponding ID tag, and each remote controller has a different ID tag. For example, the remote controller at point A has ID tags 1001, 1002, and 1003; the remote controller at point B has ID tags 2001, 2002, and 2003, etc. The remote controller sends a remote control signal including an ID tag, so after the signal receiving box receives the remote control signal, the ID tags of each remote controller can be obtained based on the remote control signal.

[0084] B2: Determine the target remote controller according to a preset ID identification arrangement sequence, wherein the ID identification of the target remote controller is arranged after the ID identifications of other remote controllers that send remote control signals.

[0085] In this embodiment, the ID identification of the remote controller at each remote control site can be recorded in advance, and the ID identification arrangement order can be recorded based on the location of the remote control site. For example, from point A to point D, the corresponding ones are ID identification 1, ID identification 2, ID identification 3, and ID identification 4. After the vehicle to be tested records the ID identification order, during the test process, if at least two signal receiving boxes receive the signal frequency, it means that the vehicle to be tested is traveling from the previous remote control site to the next remote control site and has entered the remote control range of the next remote control site. The distance between the remote controller of the previous remote control site and the vehicle to be tested tends to increase, and the distance between the remote controller of the next remote control site and the vehicle to be tested tends to decrease. By sorting the ID identification, it is determined which remote control signal is sent by the remote controller of the previous remote control site and which remote control signal is sent by the remote controller of the next remote control site, and the remote controller of the next remote control site is used as the target remote controller.

[0086] In this embodiment, the target remote control is determined by the remote control ID identification. During the remote control switching process, the remote control that will take over the control of the vehicle to be tested can be automatically and accurately identified, and the signal frequencies of the remote controls can be selected to be the same or different, thereby increasing flexibility and convenience.

[0087] S302, determining a target control instruction according to a remote control signal sent by a target remote controller;

[0088] In this step, the vehicle to be tested only responds to the remote control signal sent by the target remote control, so the target control instruction is determined based on the remote control signal sent by the target remote control.

[0089] S303: Control the vehicle to be tested according to the target control instruction, so that the driving condition of the vehicle to be tested reaches the target condition required for the chassis test.

[0090] The specific implementation process of step S303 is the same as above. Figure 2 The specific implementation process of the exemplary step S202 is similar, and the details may be referred to the above embodiment, which will not be described again.

[0091] In an optional implementation, since the remote control is manually operated, and different people operate different remote controls at different locations, in order to smoothly switch the remote control control so that the entire test process can be completed normally and the safety of the test process is ensured, when it is determined that at least two signal receiving boxes have received the remote control signal, the double flash indicator light of the vehicle to be tested is controlled to be turned on, or when the vehicle to be tested responds to the remote control signal of the target remote control, the double flash indicator light of the vehicle to be tested is controlled to be turned on. After the vehicle to be tested turns on the double flash indicator light, the relay operator can be prompted that the remote control operated by the operator has successfully controlled the vehicle to be tested and maintained at the maximum gear to control the vehicle to be tested. Optionally, when a signal receiving box of the vehicle to be tested receives the remote control signal, the double flash indicator light is turned off.

[0092] In this embodiment, when at least two signal receiving boxes receive remote control signals, the vehicle to be tested automatically responds to the remote control signals of the remote control that is getting closer and closer, and switches the remote control to the remote control seamlessly, so that during driving, it is always within the remote control range of the remote control, providing a sufficiently long remote control distance for the vehicle to be tested.

[0093] Figure 5 A schematic flow chart of a vehicle chassis testing method provided in another embodiment of the present application is shown as follows: Figure 5 As shown, this embodiment, based on all the above embodiments, describes in detail the vehicle chassis testing method, which includes:

[0094] S501, determining a control instruction corresponding to the remote control signal from the remote control signal received by the signal receiving box;

[0095] It should be noted that the remote controller can send out various types of remote control signals, and different types of remote control signals correspond to different control instructions. For example, the control instructions include acceleration, turning, braking and other control instructions.

[0096] S502: Based on a preset control instruction priority, determine a control instruction with a high priority as a target control instruction.

[0097] Among them, the order of priority of the control instructions from high to low is: braking control instruction, acceleration control instruction.

[0098] The remote controller is adapted to the vehicle's automatic driving function, including braking control commands, acceleration control commands, turning control commands, etc. The operator can select the corresponding command according to the actual driving conditions of the vehicle to be tested.

[0099] In this embodiment, multiple signal receiving boxes are set based on the vehicle to be tested, and multiple remote controllers are used to control the vehicle to be tested for chassis testing. During the test, the vehicle to be tested may receive at least two remote control signals, and the control instructions corresponding to the at least two remote control signals may be different or mutually exclusive. For example, the remote control signal sent by the remote controller corresponding to point A corresponds to instructing the vehicle to brake, and the remote control signal sent by the remote controller corresponding to point B corresponds to instructing the vehicle to accelerate. The acceleration and braking instructions are mutually exclusive. If the measurement to be tested responds to the acceleration instruction and ignores the braking instruction, it may cause dangerous driving and affect the test safety.

[0100] Based on this, all control instructions are prioritized and the control instruction with the highest priority is determined as the target control instruction. For example, the braking control instruction has the highest priority, followed by the acceleration control instruction. When at least two control instructions are obtained, and the control instructions are the braking control instruction and the acceleration control instruction, even if the acceleration control instruction is issued by the target remote controller, the braking control instruction is responded to first.
