[0050] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0051] The following description, with reference to the accompanying drawings, outlines a method, apparatus, vehicle, and storage medium for calculating vehicle steering angle signals according to embodiments of this application. Addressing the problem mentioned in the background art where a steering angle sensor malfunctions, making timely remediation impossible through steering angle control methods related to its function, thus posing significant safety risks to the vehicle and user, this application provides a method for calculating vehicle steering angle signals. In this method, a first steering angle signal collected by a steering angle sensor and a rack travel signal collected by a rack travel sensor are received. The rack travel signal is converted into a second steering angle signal. The target steering angle signal of the vehicle is determined based on the first and / or second steering angle signals, thereby enabling steering angle control of the vehicle. This solves the problem of the inability to promptly remedy a steering angle sensor malfunction through steering angle control methods related to its function, thus posing significant safety risks to the vehicle and user. By installing a rack travel sensor on the vehicle steering gear housing to acquire the steering angle signal, dual redundancy is achieved in conjunction with the steering angle sensor to control the steering angle signal, providing crucial protection for the user's safe driving.

[0052] Specifically, Figure 1 This is a flowchart illustrating a method for calculating vehicle turning angle signals provided in an embodiment of this application.

[0053] like Figure 1 As shown, a rack and pinion travel sensor is installed on the steering gear housing of the vehicle. The method for calculating the vehicle's steering angle signal includes the following steps:

[0054] In step S101, the first angle signal collected by the angle sensor is received.

[0055] Specifically, in this embodiment, the steering angle signal, as an important output signal of the vehicle control system and also one of the key vehicle status signals, directly determines the vehicle control system's judgment of the vehicle's yaw angle and the vehicle's impending driving state, playing a crucial role in vehicle driving safety. Therefore, this embodiment requires the collection of relevant steering angle signals to achieve the purpose of safe vehicle steering.

[0056] Furthermore, in this embodiment, the first angle signal emitted by the angle sensor on the steering column is first collected and input to the vehicle control system; secondly, a signal processing module and algorithm model are added to the vehicle control system, and the first angle signal in the vehicle control system is processed by relevant calculations to output the signal calibration value obtained from the first angle signal.

[0057] In step S102, the rack stroke signal collected by the rack stroke sensor is received and converted into a second rotation angle signal.

[0058] Furthermore, in some embodiments, converting the rack travel signal into a second rotation angle signal includes: converting the rack travel signal into a second rotation angle signal based on a preset rack travel signal-rotation angle signal relationship.

[0059] The preset rack stroke signal-rotation angle signal relationship can be a relationship threshold set by those skilled in the art based on actual application, or it can be a relationship threshold obtained through multiple computer simulations, and no specific limitation is made here.

[0060] Specifically, such as Figure 2 and Figure 3 As shown, in order to achieve the dual redundancy design of the corner signal in this embodiment of the application and improve the accuracy and safety of the corner signal, this embodiment of the application first installs a rack travel sensor in the steering gear housing of the vehicle, and sends the output rack travel signal to the vehicle control system by measuring the rack travel; secondly, based on the preset rack travel signal-corner signal relationship, the rack travel signal is converted into a second corner signal by the signal processing module and algorithm model in the vehicle control system, thereby outputting the signal calibration value obtained from the second corner signal.

[0061] In step S103, a target steering angle signal for the vehicle is determined based on the first steering angle signal and / or the second steering angle signal, so as to perform steering angle control on the vehicle based on the target steering angle signal.

[0062] Further, in some embodiments, determining the target turning angle signal of the vehicle based on the first turning angle signal and / or the second turning angle signal includes: obtaining a first difference between the first turning angle signal and a preset calibration turning angle signal; obtaining a second difference between the second turning angle signal and the preset calibration turning angle signal; if both the first difference and the second difference are less than or equal to a preset threshold, then obtaining the target turning angle signal based on the average value of the first turning angle signal and the second turning angle signal or the preset calibration turning angle signal.

[0063] The preset calibration angle signal and preset threshold can be calibration signals and thresholds set by those skilled in the art according to actual applications, or they can be calibration signals and thresholds obtained through multiple computer simulations, and no specific limitation is made here.

[0064] Specifically, such as Figure 4 As shown in this embodiment, the difference between the obtained first angle signal and the preset calibration angle signal is calculated to obtain the first difference between the first angle signal and the preset calibration angle signal. Similarly, the difference between the obtained second angle signal and the preset calibration angle signal is calculated to obtain the first difference between the second angle signal and the preset calibration angle signal. If both the first difference and the second difference are less than or equal to a preset threshold, it indicates that both the angle sensor and the rack travel sensor are working normally. At this time, the target angle signal can be obtained based on the average value of the first angle signal and the second angle signal or the preset calibration angle signal, and then transmitted to the vehicle controller to control the vehicle's angle based on the target angle signal.

[0065] Furthermore, in some embodiments, the above-mentioned method for calculating the vehicle turning angle signal further includes: if the first difference is greater than a preset threshold and the second difference is less than or equal to the preset threshold, then the second turning angle signal is used as the target turning angle signal; if the second difference is greater than the preset threshold and the first difference is less than or equal to the preset threshold, then the first turning angle signal is used as the target turning angle signal.

[0066] Specifically, such as Figure 4 As shown in this embodiment, if the first difference between the calculated first angle signal and the preset calibration angle signal is greater than a preset threshold, and the second difference between the second angle signal and the preset calibration angle signal is less than or equal to the preset threshold, it indicates that the rack travel sensor is working normally, but the angle sensor is malfunctioning and cannot output a valid angle signal. Therefore, the second angle signal can be used as the target angle signal to control the vehicle's angle based on the second angle signal. If the second difference between the calculated second angle signal and the preset calibration angle signal is greater than a preset threshold, and the first difference between the first angle signal and the preset calibration angle signal is less than or equal to the preset threshold, it indicates that the angle sensor is working normally, but the rack travel sensor is malfunctioning and cannot output a valid angle signal. Therefore, the first angle signal can be used as the target angle signal to control the vehicle's angle based on the first angle signal.

[0067] Furthermore, in some embodiments, the above-mentioned method for calculating the vehicle turning angle signal further includes: generating a fault reminder if both the first difference and the second difference are greater than a preset threshold; controlling the vehicle's in-vehicle display terminal to display the fault reminder; and / or sending the fault reminder to a preset mobile terminal.

[0068] The preset mobile terminal can be a mobile terminal set by the user according to their usage habits, or a mobile terminal set by a person skilled in the art; no specific limitation is made here.

[0069] Specifically, in this embodiment, if the first difference between the first angle signal and the preset calibration angle signal and the second difference between the second angle signal and the preset calibration angle signal are both greater than a preset threshold, it indicates that both the angle sensor and the rack travel sensor are faulty and cannot output a valid angle signal. In this case, an angle signal fault reminder can be generated and sent to the vehicle display to show the fault reminder and / or sent to a preset mobile terminal, such as the user's mobile phone, to remind the user that the vehicle's angle signal is faulty and to drive safely.

[0070] According to the vehicle steering angle signal calculation method of this application embodiment, a first steering angle signal collected by a steering angle sensor and a rack travel signal collected by a rack travel sensor are received, and the rack travel signal is converted into a second steering angle signal. The target steering angle signal of the vehicle is determined based on the first and / or second steering angle signals, thereby controlling the vehicle's steering angle. This solves the problem that when a steering angle sensor malfunctions, it is impossible to promptly remedy the situation using steering angle control methods related to its function, thus posing a significant safety risk to the vehicle and the user. By installing a rack travel sensor on the vehicle steering gear housing to obtain the steering angle signal, the requirement of dual redundancy for steering angle signal control is achieved together with the steering angle sensor, providing an important guarantee for the user's safe driving.

[0071] Next, with reference to the accompanying drawings, a calculation device for vehicle turning angle signals according to an embodiment of this application is described.

[0072] Figure 5 This is a block diagram of a vehicle turning angle signal calculation device according to an embodiment of this application.

[0076] Control module 300 is used to determine the target steering angle signal of the vehicle based on the first steering angle signal and / or the second steering angle signal, so as to perform steering angle control on the vehicle according to the target steering angle signal.

[0077] Furthermore, in some embodiments, the control module 300 is specifically used for:

[0078] Obtain the first difference between the first turning angle signal and the preset calibration turning angle signal;

[0079] Obtain the second difference between the second angle signal and the preset calibration angle signal;

[0080] If both the first difference and the second difference are less than or equal to a preset threshold, the target turning angle signal is obtained based on the average of the first turning angle signal and the second turning angle signal or the preset calibrated turning angle signal.

[0081] Furthermore, in some embodiments, the vehicle turning angle signal calculation device 10 described above is also used for:

[0082] If the first difference is greater than the preset threshold and the second difference is less than or equal to the preset threshold, then the second corner signal is taken as the target corner signal.

[0083] If the second difference is greater than the preset threshold and the first difference is less than or equal to the preset threshold, then the first turning signal is taken as the target turning signal.

[0084] Furthermore, in some embodiments, the vehicle turning angle signal calculation device 10 described above is also used for:

[0085] If both the first and second differences are greater than the preset threshold, a fault alert will be generated.

[0086] The vehicle's onboard display terminal can display fault alerts and / or send fault alerts to preset mobile terminals.

[0087] Furthermore, in some embodiments, the second receiving module 200 is specifically used for:

[0088] Based on the preset relationship between rack travel signal and rotation angle signal, the rack travel signal is converted into a second rotation angle signal.

[0089] The vehicle steering angle signal calculation device according to an embodiment of this application receives a first steering angle signal collected by a steering angle sensor and a rack travel signal collected by a rack travel sensor, converts the rack travel signal into a second steering angle signal, determines the target steering angle signal of the vehicle based on the first steering angle signal and / or the second steering angle signal, and then performs steering angle control on the vehicle. This solves the problem that when a steering angle sensor malfunctions, it is impossible to promptly remedy the situation using steering angle control methods related to its function, thus posing a significant safety risk to the vehicle and the user. By installing a rack travel sensor on the vehicle steering gear housing to obtain the steering angle signal, the device achieves dual redundancy in steering angle signal control together with the steering angle sensor, providing an important guarantee for the user's safe driving.
