Abstract

The present application relates to the technical field of vehicle control, and provides a control method and system for a show car mode and a vehicle, which comprises the following steps: acquiring an accelerator pedal opening degree, a brake pedal state and a P-gear button state; under the condition that the show car mode is allowed to be started, if the accelerator pedal opening degree exceeds a threshold value, the brake pedal state is that the brake pedal is stepped on, and the P-gear button state is that the P-gear button is pressed, the show car mode is started. Not only the probability of false triggering of starting the show car mode is reduced, but also the situation that the show car mode cannot be entered or exited due to the failure of other controllers on the vehicle is avoided.

Description

Technical Field

[0001] This invention belongs to the field of vehicle control technology, and particularly relates to a control method, system and vehicle for a vehicle display mode. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] To ensure the safety of visitors and other onlookers, the vehicles are generally displayed in an "OFF" state at exhibitions, with all modules inactive. Customers can only view static parameters such as the vehicle's exterior, interior, and configuration information, but cannot experience the vehicle's performance in operation, resulting in a less than ideal sensory experience.

[0004] To give customers a deeper understanding of the vehicle, some exhibitions allow customers to experience the vehicle while it is on display.

[0005] During vehicle displays, users are generally not allowed to operate the vehicle for safety reasons. Common operations include using a control key, but without the key, users cannot fully experience the vehicle's functions, which limits the display vehicle. Alternatively, a diagnostic tool can be used to enter a specific mode, rendering the vehicle unable to drive. However, this is also limited by the availability of diagnostic tools, making it difficult to quickly and easily control the display vehicle's mode, which is inconvenient.

[0006] As a non-customer-oriented mode, the display vehicle mode aims to minimize accidental activation by users. However, existing control methods for display vehicle modes, such as the patent application number 202110678469.0 entitled "Vehicle and its Control Method, Device and Storage Medium, Electronic Equipment," limit activation to the multi-function buttons on the multi-function steering wheel, an area easily accessible to drivers and passengers, thus posing a certain probability of accidental activation. Furthermore, while the core function of display vehicle mode is to prohibit driving, the signals from the multi-function steering wheel buttons are generally not directly connected to the vehicle controller, resulting in a long transmission link. In cases of poor signal strength, reception delays, or malfunctions in intermediate controllers, it becomes impossible to smoothly enter or exit display vehicle mode. Summary of the Invention

[0007] In order to solve the technical problems existing in the background art, the present invention provides a control method, system and vehicle for display vehicle mode, which not only reduces the probability of false triggering of display vehicle mode, but also avoids the situation where other controllers on the vehicle fail to enter or exit display vehicle mode.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] The first aspect of the present invention provides a method for controlling a vehicle display mode, comprising:

[0010] Get the accelerator pedal opening, brake pedal status, and P gear button status;

[0011] If the accelerator pedal opening exceeds a threshold, the brake pedal is in the depressed position, and the P gear button is in the pressed position, then the display vehicle mode is activated when the display vehicle mode is allowed.

[0012] Furthermore, when the vehicle display mode is activated, the motor is prohibited from outputting torque.

[0013] Furthermore, under the condition that the display vehicle mode is allowed to be turned on, if the duration of the accelerator pedal opening exceeding the threshold exceeds the set duration, the duration of the brake pedal being in the brake pedal depressed state exceeds the set duration, and the duration of the P gear button being pressed exceeds the set duration, then the display vehicle mode is turned on.

[0014] Furthermore, the conditions under which the vehicle display mode can be activated include: the vehicle display mode is not activated, the low-voltage power supply is effective, and the gear shift mechanism is in P gear.

[0015] Furthermore, the conditions under which the vehicle display mode can be enabled include: normal communication between the vehicle controller and the shift mechanism, accelerator pedal, and brake pedal.

[0016] Furthermore, when the vehicle is powered off and then powered on again while the display vehicle mode is active, the display vehicle mode remains active.

[0017] Furthermore, when the vehicle display mode is activated, if the accelerator pedal opening exceeds a threshold, the brake pedal is in the depressed state, and the P gear button is in the pressed state, then the vehicle display mode is exited.

[0018] A second aspect of the present invention provides a control system for a vehicle display mode, comprising:

[0019] The data acquisition module is configured to acquire the accelerator pedal opening, brake pedal status, and P gear button status.

[0020] The detection module is configured to activate the vehicle display mode if, under the condition that the accelerator pedal opening exceeds a threshold, the brake pedal is depressed, and the P-gear button is pressed, the vehicle display mode is activated.

[0021] A third aspect of the present invention provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of a control method for a vehicle display mode as described above.

[0022] A fourth aspect of the present invention provides a computer device including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the program to implement the steps of a vehicle display mode control method as described above.

[0023] A fifth aspect of the present invention provides a computer program product containing a computer program, which, when executed by a processor, implements the steps in the control method for a vehicle display mode as described above.

[0024] A sixth aspect of the present invention provides a vehicle utilizing a vehicle display mode control method as described in the first aspect; or, including a vehicle display mode control system as described in the second aspect; or, including a computer-readable storage medium as described in the third aspect; or, including a computer device as described in the fourth aspect.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] The conditions for activating the display vehicle mode of this invention include the accelerator pedal opening exceeding a threshold, the brake pedal being depressed and the P gear button being pressed. When the driver simultaneously presses the brake pedal, accelerator pedal and P gear button, it is a clear expression of driving intention. Moreover, the probability of pressing the above three pedals / buttons at the same time is extremely low, reducing the probability of false triggering of the display vehicle mode.

[0027] The brake pedal status signal, accelerator pedal opening signal, and P gear button signal in the activation conditions of the vehicle display mode of this invention are all directly received by the vehicle controller. The signal transmission link is short and the reliability is high, avoiding the situation where other controllers on the vehicle cannot enter or exit the vehicle display mode due to failure.

[0028] The conditions for activating the vehicle display mode of this invention include the accelerator pedal opening exceeding a threshold for a duration exceeding a set time, the brake pedal being in a depressed state for a duration exceeding a set time, and the P gear button being pressed for a duration exceeding a set time. The probability of the driver simultaneously pressing the above three pedals / buttons is extremely low, so the probability of simultaneously pressing the above three pedals / buttons for a duration exceeding the set time is basically 0, which can completely avoid the accidental triggering of the vehicle display mode.

[0029] The present invention's vehicle display mode prohibits the motor from outputting torque but does not prohibit other functions, ensuring that users can fully experience all the vehicle's functions.

[0030] When the vehicle is powered off and then powered on again, the present invention maintains the display vehicle mode, thus avoiding repeated actions by the operator.

[0031] The exit conditions for the display vehicle mode of this invention include the accelerator pedal opening exceeding a threshold, the brake pedal being depressed and the P gear button being pressed. When the driver simultaneously presses the brake pedal, accelerator pedal and P gear button, it is a clear expression of driving intention. Moreover, the probability of pressing the above three pedals / buttons at the same time is extremely low, reducing the probability of false triggering of the display vehicle mode exit.

[0033] Figure 1 This is a flowchart of a control method for a vehicle display mode according to Embodiment 1 of the present invention. Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0035] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0036] Terminology Explanation:

[0037] Vehicle controller: The core control component of the entire vehicle, equivalent to the brain of the car; it collects signals from the accelerator pedal, brake pedal, and other components, makes corresponding judgments, and controls the actions of the lower-level component controllers to drive the car normally; as the command and management center of the car, the main functions of the vehicle controller include: drive torque control, optimized control of braking energy, energy management of the whole vehicle, maintenance and management of the CAN network, fault diagnosis and handling, vehicle status monitoring, etc., playing a role in controlling the operation of the vehicle.

[0038] Accelerator pedal: Also known as the accelerator pedal, its main function is to control the opening of the engine throttle valve, thereby controlling the engine's power output. Traditionally, the accelerator pedal is connected to the throttle valve via a cable or lever. However, with the continuous development of automotive electronics technology, electronic throttles are becoming increasingly widespread. Electronic throttles have displacement sensors installed on the accelerator pedal. When the driver presses the accelerator pedal, the ECU collects the changes in the opening of the displacement sensor and the acceleration. Based on the built-in algorithm, it determines the driver's driving intention and then sends corresponding control signals to the engine throttle valve control motor to control the engine's power output.

[0039] The brake pedal is a pedal that limits power; it is the foot brake (service brake) pedal used to slow down and stop the vehicle.

[0040] Example 1

[0041] This embodiment provides a control method for a vehicle display mode.

[0042] This embodiment provides a control method for a vehicle display mode, such as... Figure 1 As shown, it depends on the vehicle control unit (VCU) and the accelerator pedal, shift mechanism, brake pedal and instrument panel connected to the vehicle control unit.

[0043] This embodiment provides a control method for a vehicle display mode, including the following steps:

[0044] Step 1: The vehicle controller detects the status of the accelerator pedal, i.e., the accelerator pedal opening; the vehicle controller detects the status of the brake pedal; the vehicle controller detects the status of the gear shifting mechanism.

[0045] Step 2: The vehicle controller first determines whether the display vehicle mode is allowed to be enabled: the first condition is that the low-voltage power supply is valid; the second condition is that the current actual gear is in P gear, that is, the shift mechanism is in P gear; the third condition is that the vehicle controller communicates normally with the shift mechanism, accelerator pedal, and brake pedal; the fourth condition is that the display vehicle mode is not enabled.

[0046] Step 3: After the above conditions are met, and the vehicle controller detects that the following four conditions are met simultaneously, the display vehicle mode is activated: The first condition is that the shift mechanism sends a P-gear button press action (the P-gear button is in the pressed state); the second condition is that the accelerator pedal is depressed to more than 20%, that is, the accelerator pedal opening exceeds the threshold of 20%; the third condition is that the brake pedal is depressed; the fourth condition is that the first three conditions are met simultaneously for a continuous set time (10s) or more.

[0047] Step 4: After entering the display vehicle mode, the vehicle controller prevents the vehicle from entering the READY state, i.e., it prohibits the motor from outputting any torque to ensure vehicle safety. Apart from this, the vehicle controller does not disable other functions, ensuring that users can fully experience all the vehicle's functions.

[0048] Step 5: After entering the display vehicle mode, the vehicle controller sends a signal to the instrument panel indicating that the display vehicle mode has been activated. This is to inform the user that the vehicle is currently in display vehicle mode and to avoid complaints from users who are unaware of the situation and are unable to drive the vehicle.

[0049] Step 6: After entering the display vehicle mode, the vehicle controller stores the display vehicle mode state. When the vehicle is powered off and then powered on again, the display vehicle mode state is maintained to avoid repeated actions by the operator.

[0050] Step 7: After entering the display vehicle mode, the vehicle controller will exit the display vehicle mode if the following four conditions are met simultaneously: The first condition is that the shift mechanism sends the P gear button to be pressed; the second condition is that the accelerator pedal is depressed to more than 20%; the third condition is that the brake pedal is depressed; and the fourth condition is that the first three conditions are met simultaneously for more than 10 seconds.

[0051] Step 8: After exiting the display vehicle mode, the vehicle controller resumes responding to READY, resumes the motor's torque request, and the vehicle can drive normally.

[0052] Step 9: After exiting the display vehicle mode, the vehicle controller stops sending the "Display vehicle mode is enabled" message to the instrument panel, and the vehicle returns to its normal operating state.

[0053] This embodiment provides a method for controlling the display vehicle mode, which can smoothly control the display vehicle mode without affecting the user's experience of all the functions of the display vehicle (except driving).

[0054] This embodiment provides a method for controlling the vehicle display mode. It does not require operation of the central control screen or external diagnostic equipment. The purpose of controlling the vehicle display mode can be achieved through a combination of three actions, which improves convenience and expands the scope of the vehicle display.

[0055] This embodiment provides a control method for a vehicle display mode. The driver simultaneously pressing the brake pedal signal, accelerator pedal signal, and P gear button signal are all clear expressions of driving intention. Moreover, the probability of pressing the above three pedals / buttons at the same time is extremely low, reducing the probability of false triggering of the vehicle display mode.

[0056] This embodiment provides a control method for a vehicle display mode. The VCU receives brake pedal signals, accelerator pedal signals, and P gear button signals, all of which are directly received by the VCU controller. The signal transmission link is short and the reliability is high, avoiding the situation where other controllers on the vehicle cannot enter or exit the vehicle display mode due to malfunction.

[0057] This embodiment provides a control method for a vehicle display mode, which allows for offline operation of a single vehicle, debinding it from the OEM cloud / backend, reducing operating costs and improving convenience.

[0058] Example 2

[0059] This embodiment provides a control system for a vehicle display mode, which specifically includes:

[0060] The data acquisition module is configured to acquire the accelerator pedal opening, brake pedal status, and P gear button status.

[0061] The detection module is configured to activate the display vehicle mode if, under conditions where the display vehicle mode is enabled, the accelerator pedal opening exceeds a threshold, the brake pedal is depressed, and the P-gear button is pressed. Specifically, under conditions where the display vehicle mode is enabled, the display vehicle mode is activated if the duration for which the accelerator pedal opening exceeds the threshold exceeds a set duration, the duration for which the brake pedal is depressed exceeds a set duration, and the duration for which the P-gear button is pressed exceeds a set duration.

[0062] When vehicle mode is activated, the motor is prohibited from outputting torque.

[0063] The conditions under which the display vehicle mode can be activated include: the display vehicle mode is not activated, the low-voltage power supply is effective, the gear shift mechanism is in P gear, and the communication between the vehicle controller and the gear shift mechanism, accelerator pedal and brake pedal is normal.

[0064] Specifically, when the vehicle is in display mode, it remains in display mode even after the vehicle is powered off and then powered on again.

[0065] The detection module is also configured to exit the display vehicle mode if, when the display vehicle mode is enabled, the accelerator pedal opening exceeds a threshold, the brake pedal is in the "brake pedal depressed" state, and the P gear button is in the "pressed" state.

[0066] This embodiment provides a control system for a vehicle exhibition mode that can smoothly control the vehicle exhibition mode without affecting the user's experience of all the functions of the vehicle (except driving).

[0067] This embodiment provides a control system for a vehicle display mode that does not require operation of a central control screen or external diagnostic equipment. It achieves the purpose of controlling the vehicle display mode through a combination of three actions, which improves convenience and expands the scope of vehicle display.

[0068] This embodiment provides a control system for a vehicle display mode. The driver simultaneously pressing the brake pedal, accelerator pedal, and P gear button signals are all clear expressions of driving intention. The probability of pressing all three pedals / buttons at the same time is extremely low, reducing the probability of false triggering of the vehicle display mode.

[0069] This embodiment provides a control system for a vehicle display mode. The VCU receives brake pedal signals, accelerator pedal signals, and P gear button signals, all of which are directly received by the VCU controller. This results in a short signal transmission link, high reliability, and avoids situations where failure of other controllers on the vehicle prevents entry into or exit from the vehicle display mode.

[0070] This embodiment provides a control system for a vehicle display mode, which allows for offline operation of a single vehicle, decoupling from the OEM cloud / backend, reducing operating costs and improving convenience.
