DETAILED DESCRIPTION

[0039] 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 embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0040] The emergency steering system is a backup system that can provide emergency steering function when the main steering system of the vehicle fails or the engine is turned off. When the vehicle encounters an emergency, the emergency steering system can still control the direction of the vehicle, ensuring the safety of driving. At present, the development time of the emergency steering system on the market is relatively short, and the triggering conditions of the emergency steering system are that the vehicle is traveling at a high speed and the engine stops working. Therefore, during the offline inspection of the vehicle, if the performance of the emergency steering system is to be tested by simulating the failure of the main steering system of the vehicle, the engine of the vehicle cannot work. Since the engine of the vehicle cannot work and cannot meet the requirement of the higher driving speed of the vehicle, it cannot meet the triggering conditions of the emergency steering system, and the emergency steering system will be in standby state. Therefore, during the offline inspection of the vehicle, there is a problem that the function of the emergency steering system installed on the vehicle cannot be tested.

[0041] The present disclosure provides an emergency steering system detection method, such as Figure 1 As shown, the method includes:

[0042] S100: Stop the communication between the vehicle and the emergency steering system to enable the emergency steering system to be controlled.

[0043] S200. Send a speed signal to the emergency steering system.

[0044] S300: When receiving a feedback signal sent by the emergency steering system, determine whether the emergency steering system functions normally according to the speed signal and the feedback signal.

[0045] In this embodiment, the communication between the vehicle and the emergency steering system is stopped so that the emergency steering system can be controlled. A speed signal is sent to the emergency steering system, and the function of the emergency steering system is triggered by the speed signal, thereby providing a trigger condition for the emergency steering system. When a feedback signal sent by the emergency steering system is received, it is determined whether the function of the emergency steering system is normal based on the speed signal and the feedback signal. By stopping the communication between the vehicle and the emergency steering system and sending a speed signal to the emergency steering system, the environmental conditions of the main steering system failure of the vehicle can be simulated during the vehicle offline inspection, so that the function of the emergency steering system can be tested. Moreover, since the feedback signal is related to the speed signal, it is possible to determine whether the function of the emergency steering system is normal through the feedback signal and the speed signal, thereby improving the accuracy of the function detection.

[0046] Illustratively, the emergency steering system may include an emergency steering pump.

[0047] In one embodiment, the speed signal includes a first speed signal and a second speed signal, and the first speed signal is different from the second speed signal.

[0048] In this embodiment, when different speed signals are sent to the emergency steering system, the received feedback signals are also different. By sending different first speed signals and second speed signals to the emergency steering system, it can be determined whether the function of the emergency steering system is normal based on the first speed signal and the corresponding feedback signal and the second speed signal and the corresponding feedback signal, thereby improving the accuracy of function detection.

[0049] Exemplarily, the speed signal may also include a third speed signal, a fourth speed signal, and other speed signals, wherein the first speed signal, the second speed signal, the third speed signal, the fourth speed signal, and other speed signals are different from each other.

[0050] In one embodiment, the speed in the first speed signal is greater than or equal to 5 km / h.

[0051] In this embodiment, when the vehicle is traveling at a speed greater than or equal to 5 km / h, the vehicle is traveling at a high speed. At this time, when the main steering system fails, the emergency steering system needs to be triggered to ensure driving safety. Therefore, the speed in the first speed signal is set to be greater than or equal to 5 km / h, and the function of the emergency steering system is tested. In the case where the emergency steering system needs to be triggered, the feedback signal is used to determine whether the function of the emergency steering system is normal, thereby improving the accuracy of the function test.

[0052] For example, the speed in the first speed signal may be 5 km / h, 10 km / h, 15 km / h or 20 km / h, etc.

[0053] In one embodiment, the speed in the second speed signal is less than 5 km / h.

[0054] In this embodiment, when the vehicle is traveling at a speed less than 5 km / h, the vehicle is traveling at a low speed. At this time, when the main steering system fails, it is assumed that the vehicle can stop at a low speed without triggering the emergency steering system. Therefore, the speed in the second speed signal is set to be less than 5 km / h, and the function of the emergency steering system is tested. Without triggering the emergency steering system, whether the function of the emergency steering system is normal is determined through the feedback signal, thereby improving the accuracy of the function test.

[0055] For example, the speed in the second speed signal may be 1 km / h, 2 km / h, 3 km / h, 4 km / h, etc.

[0056] For example, due to different performances of different emergency steering systems, the emergency steering system may also be triggered when the speed in the second speed signal is less than 5 km / h.

[0057] In one embodiment, the step S300 of determining whether the emergency steering system functions normally according to the speed signal and the feedback signal is performed in the following manner:

[0058] If the feedback signal matches the speed signal, it is determined that the emergency steering system is functioning properly.

[0059] If the feedback signal does not match the speed signal, it is determined that the emergency steering system is malfunctioning.

[0060] In this embodiment, when the emergency steering system functions normally, a speed signal is sent and a matching feedback signal can be received. Whether the emergency steering system functions normally is determined by whether the feedback signal matches the speed signal, which reduces the complexity of the emergency steering system function detection and thus improves the efficiency of the emergency steering system function detection.

[0061] In one embodiment, the feedback signal includes a standby signal, which indicates that the emergency steering system is in a standby state.

[0062] In this embodiment, when a relatively low speed signal is sent to the emergency steering system, if the feedback signal received from the emergency steering system is a standby signal, it indicates that the main steering system of the vehicle is faulty and the emergency steering system is in a standby state while the vehicle is running at a relatively low speed, and the emergency steering system functions normally. When a relatively high speed signal is sent to the emergency steering system, if the feedback signal received from the emergency steering system is a standby signal, it indicates that the main steering system of the vehicle is faulty and the emergency steering system is still in a standby state while the vehicle is running at a relatively high speed, and the emergency steering system functions abnormally. Whether the standby signal is received under different speed signals can be used to verify whether the emergency steering system functions normally, thereby improving the accuracy of function detection.

[0063] In one embodiment, the feedback signal includes a working signal, and the working signal indicates that the emergency steering system has been activated.

[0064] In this embodiment, when a relatively low speed signal is sent to the emergency steering system, if the feedback signal received from the emergency steering system is a working signal, it indicates that the main steering system of the vehicle fails and the emergency steering system is started during the vehicle running at a relatively low speed, and the emergency steering system functions abnormally. When a relatively high speed signal is sent to the emergency steering system, if the feedback signal received from the emergency steering system is a working signal, it indicates that the main steering system of the vehicle fails and the emergency steering system is started during the vehicle running at a relatively high speed, and the emergency steering system functions normally. By determining whether the working signal is received at different speed signals, it is possible to verify whether the emergency steering system functions normally, thereby improving the accuracy of function detection.

[0065] In one embodiment, the feedback signal includes a fault signal, and the fault signal indicates that a fault occurs in the emergency steering system.

[0066] In this embodiment, no matter whether a low speed signal or a high speed signal is sent to the emergency steering system, when the feedback signal received from the emergency steering system is a fault signal, it indicates that the emergency steering system cannot be started normally and the emergency steering system functions abnormally. By checking whether a fault signal is received under different speed signals, it is possible to verify whether the emergency steering system functions normally, thereby improving the accuracy of function detection.

[0067] Exemplarily, when the emergency steering system functions normally, if the speed signal sent is the first speed signal, the received feedback signal should be a working signal. That is, the speed signal sent is the first speed signal and the feedback signal received is a working signal, and the feedback signal matches the speed signal. The speed signal sent is the first speed signal and the feedback signal received is a standby signal or a fault signal, and the feedback signal does not match the speed signal. If the speed signal sent is the second speed signal, the received feedback signal should be a standby signal. That is, the speed signal sent is the second speed signal and the feedback signal received is a standby signal, and the feedback signal matches the speed signal. The speed signal sent is the second speed signal and the feedback signal received is a working signal or a fault signal, and the feedback signal does not match the speed signal.

[0068] In one embodiment, after determining whether the emergency steering system functions normally according to the speed signal and the feedback signal in step S300, the emergency steering system detection method further includes:

[0069] Restore communication between the vehicle and the emergency steering system.

[0070] In this embodiment, after the emergency steering system function is detected, no matter whether the emergency steering system function is normal or not, the communication between the vehicle and the emergency steering system is restored. In this way, the functions of other systems in the vehicle can be detected, and the faulty emergency steering system can be further checked, thereby improving the reliability of vehicle offline detection.

[0071] Exemplarily, the restoration of communication between the vehicle and the emergency steering system in the above steps is determined by:

[0072] The target data is sent to the vehicle so as to restore communication with the emergency steering system when the vehicle receives the target data.

[0073] In one embodiment, before sending the speed signal to the emergency steering system in step S200, the emergency steering system detection method further includes:

[0074] When receiving the encrypted data sent by the vehicle, the encrypted data is decrypted to obtain the decrypted data.

[0075] The decrypted data is sent to the vehicle in a preset format so that the vehicle can recognize the decrypted data and open the communication network after successful recognition. The communication network is used to control the emergency steering system.

[0076] In this embodiment, the vehicle opens the communication network by decrypting the encrypted data and sending the decrypted data in a preset format, thereby improving the security of the communication network opening and the integrity of data transmission, thereby improving the reliability of function detection.

[0077] The present disclosure provides an emergency steering system detection method, such as Figure 2 As shown, the method includes:

[0078] S400: When receiving the encrypted data sent by the vehicle, decrypt the encrypted data to obtain decrypted data.

[0079] S410, sending the decrypted data to the vehicle in a preset format so that the vehicle can identify the decrypted data, and after successful identification, opening the communication network and stopping the communication between the vehicle and the emergency steering system so that the emergency steering system can be controlled.

[0080] S420: Send a first speed signal of 5 km / h to the emergency steering system.

[0081] S430: Determine whether the received feedback signal is a working signal. If yes, execute step S440. If no, determine that the emergency steering system is abnormal.

[0082] S440: Send a second speed signal of 2 km / h to the emergency steering system.

[0083] S450: Determine whether the received feedback signal is a standby signal. If so, determine that the emergency steering system functions normally. If not, determine that the emergency steering system functions abnormally.

[0084] In this embodiment, the communication between the vehicle and the emergency steering system is stopped so that the emergency steering system can be controlled. A speed signal is sent to the emergency steering system, and the function of the emergency steering system is triggered by the speed signal, thereby providing a trigger condition for the emergency steering system. When a feedback signal sent by the emergency steering system is received, it is determined whether the function of the emergency steering system is normal based on the speed signal and the feedback signal. By stopping the communication between the vehicle and the emergency steering system and sending a speed signal to the emergency steering system, the environmental conditions of the main steering system failure of the vehicle can be simulated during the vehicle offline inspection, so that the function of the emergency steering system can be tested. Moreover, since the feedback signal is related to the speed signal, it is possible to determine whether the function of the emergency steering system is normal through the feedback signal and the speed signal, thereby improving the accuracy of the function detection.

[0085] An exemplary embodiment of the present disclosure provides an emergency steering system detection device, which is used to implement the above method. Figure 3 As shown, the emergency steering system detection device may include a stop module 10, a sending module 20 and a determination module 30, wherein, in the process of implementing the above method,

[0086] The stopping module 10 is used to stop the communication between the vehicle and the emergency steering system so that the emergency steering system can be controlled.

[0087] The sending module 20 is used to send a speed signal to the emergency steering system.

[0088] The determination module 30 is used to determine whether the emergency steering system functions normally according to the speed signal and the feedback signal when receiving the feedback signal sent by the emergency steering system.

[0089] In an exemplary embodiment, an emergency steering system detection device is provided, in which a determination module 30 is configured to:

[0090] If the feedback signal matches the speed signal, it is determined that the emergency steering system is functioning properly.

[0091] If the feedback signal does not match the speed signal, it is determined that the emergency steering system is malfunctioning.

[0092] Each module in the above-mentioned emergency steering system detection device can be implemented in whole or in part by software, hardware or a combination thereof. Each of the above-mentioned modules can be embedded in or independent of the processor in the emergency steering system detection device in the form of hardware, or can be stored in the memory in the emergency steering system detection device in the form of software, so that the processor can call and execute the corresponding operations of each of the above modules.

[0093] In an exemplary embodiment, an emergency steering system detector is provided, including a processor and a memory, wherein the memory stores a computer program, and when the processor executes the computer program, the steps of any of the above-mentioned emergency steering system detection methods are implemented.

The host 60 includes the above-mentioned memory and processor.

[0095] In this embodiment, since the emergency steering system detector is composed of a communication plug, a communication cable and a host, the structure of the emergency steering system detector is simple. Moreover, the function of the emergency steering system of the vehicle can be directly detected through the host, which reduces the complexity of the function detection.

[0096] Exemplarily, the host 60 communicates with the emergency steering system through the communication interface of the vehicle. After the emergency steering system detector is electrically connected to the communication interface of the vehicle, the host 60 can obtain relevant information such as communication information, vehicle information, vehicle code, information of each module constituting the emergency steering system, vehicle working status information, and fault information. When the emergency steering system is connected to a computer device through a USB interface, the above data can be uploaded and stored.

[0097] Exemplarily, after the emergency steering system detector is electrically connected to the communication interface of the vehicle, the communication rate of the vehicle can be determined, and the host 60 can automatically match the communication rate of the vehicle to communicate with the emergency steering system.

[0098] Exemplarily, the host 60 also includes a function selection button 61, a display screen 62, a switch 63, a USB data interface and an indicator light.

Pin 6 of the communication plug 40 is electrically connected to CAN-H2 of the communication cable 50, and pin 14 of the communication plug 40 is electrically connected to CAN-L2 of the communication cable 50, which is the second CAN communication mode. Pin 16 of the communication plug 40 is connected to the positive pole of the power supply, and pin 4 of the communication plug 40 is connected to the negative pole of the power supply.

[0099] Exemplarily, the function selection button 61 includes function buttons such as up, down, left, and right adjustment buttons, a confirmation button, and an exit button, which are used to implement operations such as function selection, confirmation, and exit. The display screen 62 is used to display function directions and operation prompts. The switch 63 is used to switch between two CAN communication modes. When switched to the first gear, the host communicates with the vehicle through the first CAN communication mode. When switched to the second gear, the host communicates with the vehicle through the second CAN communication mode. The USB data interface can be connected to a computer device for software upgrades, data reading, etc., and can also charge the host 60 through a computer device. The indicator light is used to display the charging status and the interaction status between the host 60 and the emergency steering system.
