[0022] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0023] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0024] Terminology analysis:

[0025] CAN bus (Controller Area Network) is a serial communication protocol widely used in the fields of automobiles, industrial automation, aerospace, etc. It was first proposed by Bosch in Germany in 1986 and internationally standardized through the ISO 11898 standard.

[0026] The main features of the CAN bus include a multi-master structure, that is, all nodes in the network have equal status, there is no central controller to manage communication, and each node can actively send data. This feature of no central control makes the CAN bus perform well in real-time and reliability, and is particularly suitable for systems that require high real-time and high reliability.

[0027] At the physical layer, the CAN bus uses twisted pair cables to transmit signals, which has high performance and high reliability. It completes the bit transmission of signals through two differential signal lines (CAN_H and CAN_L). In addition, the CAN bus supports both high-speed and low-speed modes, where the communication rate of high-speed CAN is 125Kbps to 1Mbps, and the communication rate of low-speed CAN is 10Kbps to 125Kbps.

[0028] In terms of application areas, CAN bus is not only widely used in automotive electronic systems, such as communication between various electronic control units inside the vehicle, but also in industrial monitoring systems, transportation vehicle electrical systems, etc. Due to its high efficiency and reliability, CAN bus is also used in ships and other industrial automation equipment.

[0029] In summary, the CAN bus, with its unique multi-host architecture, high performance and high reliability, occupies an important position in various systems that require real-time and reliable communication.

[0030] The Electric Motor Driver Controller (EMDC) is mainly used to control the driving motor of the electric vehicle to achieve normal driving and control of the electric vehicle.

[0031] The parking motor controller measures the slope through the built-in longitudinal acceleration sensor, calculates the sliding force of the vehicle on the slope due to gravity, and drives the parking motor to apply braking force to balance the sliding force of the vehicle through the parking motor controller, so that the vehicle can be stably parked on the slope or flat road to prevent the vehicle from slipping.

[0032] In-Vehicle Infotainment (IVI) is an integrated in-vehicle information processing system that uses a dedicated in-vehicle central processor, based on the vehicle body bus system and Internet services. IVI can realize a series of applications including three-dimensional navigation, real-time traffic conditions, IPTV, assisted driving, fault detection, vehicle information, body control, mobile office, wireless communication, online entertainment functions and TSP services, greatly improving the level of vehicle electrification, networking and intelligence.

[0033] See also Figure 1 , Figure 1The flowchart of the vehicle gear redundancy control method in one embodiment of the present application is shown in FIG. The vehicle gear redundancy control method in one embodiment of the present application comprises the following steps:

[0034] Step S100, obtaining the communication status of the shifter and the transmission status of the controller area network bus.

[0035] In one embodiment, the step of obtaining the communication status of the shifter and the transmission status of the controller area network bus includes: after the vehicle is powered on, the status of the shifter and the controller area network is monitored by the in-vehicle infotainment system controller to obtain the communication status and the transmission status. Specifically, after the vehicle is powered on at low voltage, the in-vehicle infotainment system controller (hereinafter collectively referred to as the IVI controller) can monitor the status of the vehicle's shifter and the controller area network bus (CAN bus). The communication status between the shifter and the in-vehicle infotainment system controller can be monitored to determine whether the shifter can be connected normally, and the communication status of the CAN bus can be monitored to determine whether there is any relevant gear signal transmission on the CAN bus.

[0036] Step S110, when it is determined that the shifter is faulty based on the communication status, or when it is determined that the controller area network bus is faulty based on the transmission status, the gear information is displayed through the vehicle-side display device.

[0037] In one embodiment, before the gear information is displayed by the vehicle-side display device, it also includes: matching prompt information based on the gear shifter fault or the controller local area network bus fault, and outputting the prompt information to the vehicle-side display device for display. Specifically, based on the monitored communication status, it can be determined whether the communication between the IVI controller and the gear shifter is lost, and if the communication is lost, the gear shifter fault is determined. Similarly, based on the transmission status, it can be determined whether there is a corresponding fault code on the CAN bus or when the driver switches the gear, the state of the CAN bus is abnormal, then the CAN bus fault is determined, and the corresponding prompt information can be output through the vehicle-side display device at this time. The prompt information may include "gear shifter fault", "CAN bus fault", etc., and the owner or maintenance personnel are reminded to troubleshoot the fault through the prompt information. Of course, the prompt information can also be output to relevant personnel in the form of voice broadcast. Furthermore, the prompt information can also be forwarded to the cloud or a specific user terminal through the Internet of Vehicles device for user viewing. The vehicle-side display device here can be a large central control screen or other vehicle-side display, which is not limited here.

[0038] In one embodiment, when a shifter fault or a CAN bus fault is detected, the gear information can also be displayed through a pop-up window on the central control screen, such as displaying the icons corresponding to P gear, R gear, N gear, and D gear, so that the user can interact by clicking the corresponding gear icon on the screen. Of course, the gear information can also be displayed on the screen in the form of text, buttons, etc. The display form of the specific gear information can be set and adjusted according to actual application requirements, and is not limited here.

[0039] In one embodiment, after the gear information is displayed by the vehicle-side display device, it also includes: generating a gear switching guide based on the gear information to guide the user to perform the corresponding interactive action. After the gear information is displayed on the vehicle side, the corresponding gear switching guide can be output synchronously, and the user completes the interactive action according to the prompt of the guide. The user needs to complete a specific guidance action to trigger the gear selection to avoid the risk of accidental touch. Exemplarily, the gear switching guide can be a text prompt, such as "Please press and hold the gear icon for 3 seconds". The gear switching guide is not limited to text prompts, but can also be a voice guide or a corresponding animation demonstration. The guidance information can also be any combination of voice guidance, text guidance, and animation guidance. The interactive action is not limited to clicking the screen, but can also be controlled by voice, such as inputting a specific voice command to trigger the gear selection. The specific guidance method and interaction method can be set and adjusted according to the actual application requirements, and there is no limitation here.

[0040] Step S120, in response to the user's interaction with the vehicle-side display device, determines the currently selected gear to generate a corresponding gear signal and sends it to the drive motor controller and the parking motor controller, so that the drive motor controller and the parking motor controller control the vehicle based on the gear signal.

[0041] In one embodiment, after the user completes the corresponding interactive action, the gear selected by the user can be identified based on the interactive action. The gear icon or related logo selected by the user can be displayed on the vehicle-side display device to show the user interaction result. Exemplarily, if the user selects the forward gear, a gear signal corresponding to the forward gear is generated, and the gear signal is sent to the drive motor controller and the parking motor controller. The drive motor controller performs forward gear switching and forward torque control. The drive motor performs torque control by parsing the preset torque value or the accelerator pedal's stepping depth value, so as to achieve the preset vehicle speed or the driver's ideal vehicle speed request. The parking motor controller controls the release of the parking motor according to the received gear signal. If the user selects the reverse gear, a gear signal corresponding to the reverse gear is generated, and the gear signal is sent to the drive motor controller and the parking motor controller. The drive motor controller performs reverse gear switching and reverse torque control. The drive motor performs torque control by parsing the preset torque value or the accelerator pedal's stepping depth value, so as to achieve the preset vehicle speed or the driver's ideal vehicle speed request. The parking motor controller performs clamping and release of the parking motor according to the received gear signal.

[0042] In one embodiment, before generating a corresponding gear signal and sending it to the drive motor controller and the parking motor controller so that the drive motor controller and the parking motor controller perform vehicle control based on the gear signal, the method further includes: establishing a connection between the vehicle infotainment system controller and the drive motor controller and the parking motor controller through a redundant hard line and a redundant controller area network bus for transmitting the gear signal. Specifically, a redundant hard line and a redundant CAN bus may be provided, and when a shifter fault is monitored, the redundant hard line or the redundant CAN bus may be started to send the gear signal corresponding to the gear selected by the user to the drive motor controller and the parking motor controller.

[0043] In one embodiment, after the gear switching is completed, the execution result can be fed back to the in-vehicle infotainment system controller, and the in-vehicle infotainment system controller displays the execution result on the corresponding display device so that the user can understand the current gear status of the vehicle based on the displayed execution result.

[0044] See also Figure 2 , Figure 2This is the overall process architecture diagram of vehicle gear redundancy control in one embodiment of the present application. After the vehicle is powered on, the IVI controller monitors the real-time status of the shifter (i.e., the communication status) and whether the status of the CAN bus is abnormal. When the IVI controller determines that the corresponding status is abnormal, the fault is displayed through the vehicle-side large screen, and at the same time, the vehicle-side large screen outputs guidance to prompt how to switch redundant gears; the central control large screen can dominate the screen, and the corresponding gear information can pop up for user interaction, where the gear information can be icons of P, R, N, and D gears. According to the guidance, the user presses the corresponding gear on the large screen for 3s (of course, this is only an example, and the specific duration and action can be set according to needs). After receiving the user's interactive action, the IVI controller sends a gear signal through a redundant hard line or a backup redundant CAN bus; the drive motor controller executes the vehicle's gear switching and torque control according to the received hard line signal or the gear command sent by the CAN bus; the parking motor controller executes the clamping and release of the parking motor according to the received hard line signal or the CAN bus gear command; the central control screen, instrument or HUD on the vehicle side displays the gear status transmitted by the IVI controller in real time, informing the user of the current gear status. After the gear switching is completed, the vehicle can drive or park normally.

[0045] Based on the technical solutions of the above embodiments of the present application, after the shifter fails, the vehicle's gear shifting operations can still be performed by interacting with the vehicle-side display device, so that the user can use the vehicle in an emergency; during driving, when the CAN bus fails, the vehicle's safe parking can also be guaranteed; providing a redundant control strategy for the vehicle's gear position can improve the user experience, and after the shifter and CAN bus fail, normal gear switching can still be guaranteed to meet the user's vehicle needs in different situations.
