Description

Technical Field

[0001] The present invention relates to the field of automatic start technology, and in particular to a control method, system, vehicle and storage medium for preventing accidental vehicle start. Background Technology

[0002] Currently, automatic start-up functionality is just beginning to be rolled out in commercial vehicles equipped with automatic transmissions in the domestic market, with OEMs gradually adding this feature to their vehicles. This function simplifies the vehicle starting process, reduces driver workload, and is particularly suitable for frequent start-stop scenarios in congested urban areas and high-frequency driving scenarios such as rolling back on inclines.

[0003] The factory-preset automatic start function has a relatively simple basic trigger control logic. It mainly uses the transmission control unit (TCU) in the automated manual transmission (AMT) to control the engagement of the clutch and gradually increase the driving force. Currently, because the automatic start speed is relatively slow under heavy loads, drivers who are not familiar with this function may forget to enable it by default, which can easily lead to safety accidents if they rush to get out of the car without disengaging the gear.

[0004] The automatic start process is as follows: the driver engages a gear, and only needs to release the foot brake and handbrake; the vehicle will automatically start, the engine maintains a low speed, and the vehicle will actively move forward or backward. However, in actual use, because automatic start is enabled by default, there are two high-risk accident-inducing conditions: First, the driver temporarily gets out of the car but forgets to disengage the gear and fails to engage the handbrake to apply the parking brake. The driver mistakenly believes that the vehicle will not move without pressing the accelerator, and the vehicle remains in gear without a parking protection mechanism. Second, the driver gets out of the car but forgets to disengage the gear, and after prolonged driving, the vehicle may have worn-out contact parts or malfunctions, causing the handbrake to malfunction. The vehicle controller cannot recognize the true working state of the handbrake, causing the vehicle to automatically start and move forward. In both of these situations, even if the driver has left the driver's seat and is no longer in control of the vehicle, the vehicle will still trigger the automatic start function according to the original factory logic, leading to accidents such as unexpected vehicle rollover, collision with obstacles, being run over, and vehicle damage.

[0005] Therefore, there is an urgent need for a control scheme that can effectively prevent the automatic start function of the vehicle from being activated erroneously, so as to fundamentally solve the safety hazards of automatic vehicle start when the driver is away from the vehicle. Summary of the Invention

[0006] This invention provides a control method, system, vehicle, and storage medium for preventing accidental vehicle start-up in commercial vehicles equipped with automatic transmissions, in order to solve the technical problem that the automatic start function of existing vehicles is easily triggered by accident under conditions such as when the driver leaves the vehicle, leading to safety accidents.

[0007] In a first aspect, this application provides a control method for preventing accidental vehicle start-up, applicable to vehicles equipped with a transmission control unit and a control unit, comprising:

[0008] The system acquires a door status signal and a driver presence detection signal. When the door status signal indicates that the door is closed and the driver presence detection signal indicates that the driver has entered the driver's seat, the system determines that the driver is in position and generates a driver presence signal.

[0009] After generating the driving position signal, the gear position signal, handbrake signal and brake pedal signal are acquired. When the gear position signal indicates that the vehicle is in a driving gear, the handbrake signal indicates that the handbrake has been released, and the brake pedal signal indicates that the foot brake has been released, an automatic start signal is generated and sent to the transmission control unit.

[0010] Based on the automatic start signal, the transmission control unit controls the clutch engagement and the engine speed and torque to execute automatic vehicle start.

[0011] Optionally, the driver presence detection signal includes at least one of the following signals:

[0012] The driver's seatbelt status sensor detects the action signal indicating that the seatbelt buckle has switched from the disengaged state to the engaged state;

[0013] The brake pedal sensor detects the driver's action signal of pressing the brake pedal;

[0014] The seat pressure sensor detects the pressure change signal of the seat when it switches from an unoccupied state to an occupied state.

[0015] The camera sensor detects the driver's face entering the driver's seat.

[0016] Optionally, after the step of generating the driver in position signal, the method further includes:

[0017] When the door status signal indicates that the door has switched from the closed state to the open state, or when the driver presence detection signal indicates that the driver has left the driver's seat, the driver presence signal is switched to the closed state.

[0018] When the system detects that the current transmission is in a driving gear, it sends a warning signal to the instrument panel to prompt the driver to shift the transmission to neutral.

[0019] Optionally, in the automatic start execution step, the transmission control unit controls the clutch to perform engagement action at a preset engagement rate according to the automatic start signal, and adjusts the target speed and target torque of the engine based on the current throttle opening to drive the vehicle to start automatically.

[0020] Secondly, based on the same inventive concept, embodiments of the present invention also provide a control system for preventing accidental vehicle start-up, employing a control method for preventing accidental vehicle start-up provided in the first aspect, to avoid accidental activation of the vehicle's automatic start function. The control system includes:

[0021] Transmission control unit;

[0022] An electronic control unit, communicatively connected to the transmission control unit, includes:

[0023] The signal acquisition unit is used to acquire door status signals, driver presence detection signals, gear signals, handbrake signals, and brake pedal signals;

[0024] The driver positioning determination unit is communicatively connected to the signal acquisition unit and is used to determine whether the driver is in the driving position based on the door status signal and the driver presence detection signal. When the door status signal indicates that the door is closed and the driver presence detection signal indicates that the driver has entered the driver's seat, a driver positioning signal is generated.

[0025] The starting condition determination unit is communicatively connected to the signal acquisition unit and the driver positioning determination unit. After receiving the driver positioning signal, it determines whether the automatic start operation conditions are met based on the gear signal, the handbrake signal and the brake pedal signal. When the gear signal indicates that the vehicle is in a driving gear, the handbrake signal indicates that the handbrake has been released, and the brake pedal signal indicates that the foot brake has been released, an automatic start signal is generated.

[0026] The signal output unit is communicatively connected to the start condition determination unit and is used to send the automatic start signal to the transmission control unit to trigger the transmission control unit to control the engine to increase its speed and torque, and to engage the clutch to control the vehicle to enter the automatic start function.

[0027] Optionally, the driver positioning determination unit is further configured to:

[0028] After the driver is in position signal is generated, when the door status signal indicates that the door has switched from closed to open, and / or the driver presence detection signal indicates that the driver has left the driver's seat, the driver is in position signal is switched to closed.

[0029] The control system also includes a prompting unit, which sends a prompting signal to the instrument panel to instruct the driver to shift the transmission to neutral when the driver is in position signal is switched to off and the current transmission is in driving gear.

[0030] Optionally, the signal acquisition unit acquires the door status signal, the driver presence detection signal, the gear signal, the handbrake signal, and the brake pedal signal through hard-wired signals and / or CAN communication message signals; the signal output unit sends the automatic start signal to the transmission control unit through CAN communication.

[0031] Optionally, the electronic control unit includes a vehicle control unit or a body control unit.

[0032] Thirdly, based on the same inventive concept, embodiments of the present invention also provide a vehicle employing a control method for preventing accidental vehicle start-up provided in the first aspect, to prevent accidental activation of the vehicle's automatic start function, including:

[0033] Transmission control unit;

[0034] The door status sensor is used to detect the door status and output a door status signal;

[0035] The driver presence detection sensor is used to detect whether the driver has entered the driver's seat and output a driver presence detection signal;

[0036] Gear position sensor is used to detect the gear position of the transmission and output a gear position signal;

[0037] The handbrake status sensor is used to detect the handbrake status and output a handbrake signal;

[0038] Foot brake status sensor is used to detect the foot brake status and output a brake pedal signal;

[0039] The electronic control unit is communicatively connected to the transmission control unit, the door status sensor, the driver presence detection sensor, the gear position sensor, the handbrake status sensor, and the foot brake status sensor.

[0040] Fourthly, based on the same inventive concept, embodiments of the present invention also provide a storage medium storing a computer program, which, when executed by a processor, implements a control method for preventing accidental vehicle start-up as provided in the first aspect.

[0041] In summary, the control method for preventing accidental vehicle start provided in this application ensures that automatic start is triggered only when the driver is actually in the driver's seat and in position, by introducing driver presence judgment into the automatic start trigger condition. This fundamentally eliminates safety accidents such as vehicle rollaway, collision, and run-over of people caused by automatic vehicle start after the driver leaves the vehicle.

[0047] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the invention and not all structures. Various modifications and variations can be made to the present invention without departing from its spirit or scope, which will be apparent to those skilled in the art. Therefore, the present invention is intended to cover modifications and variations falling within the scope of the corresponding claims (the claimed technical solutions) and their equivalents. It should be noted that the embodiments provided in the present invention can be combined with each other without contradiction.

[0048] In view of one or more of the above-mentioned problems existing in the prior art, the present invention proposes a control method to prevent vehicle mis-starting. Figure 1 A flowchart illustrating a control method for preventing accidental vehicle start-up provided in this application embodiment is shown below. Figure 1 This invention provides a control method to prevent accidental vehicle start-up, applicable to vehicles equipped with an electronic control unit (VCU) and a transmission control unit (TCU), to avoid accidental activation of the vehicle's automatic start function. (See reference...) Figure 1 The control method for preventing accidental vehicle start-up provided in this embodiment of the invention includes:

[0049] S101, the electronic control unit acquires the door status signal and the driver presence detection signal. When the door status signal indicates that the door is closed and the driver presence detection signal indicates that the driver has entered the driver's seat, it determines that the driver is in position and generates a driver presence signal.

[0050] Specifically, the vehicle is equipped with door status sensors, seat belt status sensors, and driver's seat occupancy detection sensors. Door status includes closed and open; gear position signals include Park (P), Reverse (R), Neutral (N), and Drive (D). Brake pedal signals include depressed and released signals, and handbrake signals include engaged and released signals. Driver presence detection signals may include, but are not limited to, seat belt status signals, such as locking and unlocked signals.

[0051] The Electronic Control Unit (VCU) collects real-time signals such as door status, driver presence, gear position, brake pedal, and handbrake. When the VCU uses door closure as a basic safety prerequisite and driver seating as the core trigger criterion, it determines the driver's position based on the following signals: door status signal indicating door closure, driver's seatbelt activation, brake application, or driver's seat occupancy sensor detecting driver entry. Upon confirming the driver's presence, a valid driver presence signal (Flag) is generated and output via the Controller Area Network (CAN) or hardwired interface.

[0052] S102. After generating the driving position signal, the electronic control unit acquires the gear position signal, handbrake signal and brake pedal signal. When the gear position signal indicates that the vehicle is in driving gear, the handbrake signal indicates that the handbrake has been released, and the brake pedal signal indicates that the foot brake has been released, an automatic start signal is generated and sent to the transmission control unit.

[0053] S103, the transmission control unit controls the clutch engagement and the engine speed and torque to increase based on the automatic start signal, thereby executing automatic vehicle start.

[0054] After generating the driver in position signal, the electronic control unit (VCU) determines that the vehicle is in the driving gear (R / D gear), the handbrake is released, and the foot brake is released based on the gear position signal, handbrake signal, and brake pedal signal. Then, it generates an automatic start signal and sends it to the transmission control unit (TCU) via the controller area network (CAN).

[0055] For example, the transmission control unit (TCU) responds to the received automatic start signal and performs start coordination control. It controls the clutch to engage according to a preset engagement rate curve, while simultaneously sending a torque boost request to the engine management system (EMS). Based on the current throttle opening, it adjusts the engine's target speed and target torque to drive the vehicle through a smooth automatic start. This application achieves a smooth automatic start through a preset engagement rate and dynamic adjustment based on throttle opening, avoiding accidental starts and thus improving driving comfort.

[0056] In summary, this invention overcomes the limitations of traditional solutions that rely solely on single conditions like gear position, handbrake, and parking brake status to determine automatic start by deeply integrating multi-source signals from standard vehicle equipment such as door status and seatbelt status, and constructing a multi-level closed-loop linkage mechanism with these sensors. Specifically, this invention introduces a two-level determination logic: "driver in position" and "starting condition." First, it accurately determines whether the driver is in position based on multi-sensor signals, using this result as the enabling condition for the automatic start function. Once enabled, the electronic control unit (ECU) only issues an automatic start command to the transmission control unit when the driver's operation meets preset driving conditions. The transmission control unit then controls clutch engagement and engine torque increase to execute a smooth start. This hierarchical control strategy significantly enhances the ability to prevent false triggering of the automatic start function, improving vehicle safety and intelligence.

[0057] In this embodiment, the driver's seat occupancy recognition sensor further includes a seat pressure sensor, a camera sensor, etc. The driver's presence detection signal includes at least one of the following signals: an action signal detected by the driver's seat belt status sensor indicating that the seat belt buckle has switched from an open state to an inserted state; an action signal detected by the brake pedal sensor indicating that the driver has pressed the brake pedal; a pressure change signal detected by the seat pressure sensor indicating that the seat has switched from an unoccupied state to an occupied state; and a recognition signal detected by the camera sensor indicating that the driver's face has entered the driver's seat.

[0058] In the process of determining driver positioning, in addition to using the door status signal and driver positioning detection signal as the main criteria, this invention can also introduce other vehicle-mounted sensing signals as auxiliary or redundant criteria to further improve the accuracy and anti-interference capability of the determination. These include, but are not limited to: a seat occupancy recognition signal output by a thin-film pressure sensor or a capacitive occupant detection sensor located under the driver's seat cushion, used to output a digital signal indicating that the seat is effectively occupied when the detected mass load is greater than a preset threshold, thus outputting a driver positioning signal; and a driver monitoring camera integrated into the rearview mirror base or the inner side of the vehicle frame, used to extract and match the driver's facial features in real time, and outputting a driver positioning signal when the recognition result matches the preset driver feature template or when the detected facial contour meets the frontal sitting posture. Each of the aforementioned auxiliary signals can be independently or in combination with the main criterion through logical "OR" or "AND" operations. For example, if the driver's seatbelt buckle fails to trigger the engagement signal due to a physical malfunction when the door is closed, the electronic control unit can still determine that the driver is in the driving position based on the logical "AND" result of the seat occupancy signal and the visual authentication signal. This achieves functional protection under single-point sensor failure and effectively distinguishes between non-driving scenarios such as "human presence" and "misplaced heavy objects," further enhancing the functional safety of the control system.

[0059] Figure 2 The loop logic diagram provided in this application embodiment represents the determination of the driver's state switching in the driver's seat, referencing... Figure 2 The logic for determining whether the driver is in the driver's seat and has taken their position in this invention, as described in the electronic control unit (VCU), is as follows:

[0060] Step S11: Power on and start the vehicle.

[0061] Step S12: Enter the loop judgment, and the default state is "driver is not in the driver's seat".

[0062] Step S13: The door status sensor detects whether the door is closed. When the door status sensor detects that the door is closed, proceed to step S14 for judgment.

[0063] Step S14: The seatbelt status sensor detects the action signal of the seatbelt buckle changing from disengaged to engaged, or the electronic control unit detects the action signal of the driver pressing the brake pedal, or other sensors detect the signal of the driver entering the driver's seat, such as the seat pressure sensor detecting the pressure change signal of the seat changing from an unoccupied state to an occupied state, or the camera sensor detecting the recognition signal of the driver's face entering the driver's seat. When any of the above signals are detected, it is determined that the driver has entered the driver's seat.

[0064] Step S15: Switch the state to "Driver has entered the driver's seat" state.

[0065] Step S16: When the door status sensor detects that the door is open, or the seat belt status sensor detects the action signal of the seat belt buckle from insertion to disengagement, or other sensors detect the signal of the driver leaving, the status switches from "driver has entered the driver's seat" back to "driver is not in the driver's seat".

[0066] During the cyclical judgment process in steps S12~S16 above, the electronic control unit (VCU) acquires door status signals and driver presence detection signals in real time through hard-wired signals or CAN communication message signals, and continuously monitors and updates the driver's presence status, adjusting the vehicle's automatic start function in real time. The dual acquisition method of hard-wired signals and CAN communication message signals ensures the reliability of signal acquisition. In particular, the CAN communication transmission method fully utilizes the vehicle's existing communication architecture, eliminating the need for additional wiring and reducing modification costs.

[0067] Specifically, after generating the driver's seat signal, the electronic control unit (VCU) continuously monitors and updates the driver's status to determine whether the driver is in the driver's seat. The control method in this step also includes:

[0068] When the door status signal indicates that the door has changed from closed to open, or when the driver presence detection signal indicates that the driver has left the driver's seat, the driver presence signal is switched to the closed state. Simultaneously, if the current transmission gear is detected as being in drive, a prompt signal is sent to the instrument panel to remind the driver to shift the transmission to neutral.

[0069] Figure 3 The logic block diagram provided in this application embodiment represents how a car triggers driver activation in the driver's seat by satisfying driver positioning conditions. (Refer to...) Figure 3 In order to satisfy Figure 2 In step S15, after determining that "the driver has entered the driver's seat", the subsequent execution of the control method and the completion of the automatic start judgment logic process are as follows:

[0070] Step S21: Power on the vehicle and start the vehicle.

[0071] Step S22: Determine whether the driver has entered the driver's seat. Figure 2 The input is obtained from the loop judgment process shown.

[0072] Step S23: When step S22 determines that the driver has entered the driver's seat, the electronic control unit (VCU) generates and records the "Automatic Start Function Driving Position Enable" signal.

[0073] Step S24: When step S22 determines that the driver has not entered the driver's seat, further determine whether the transmission is currently in gear (i.e., whether it is in driving gear).

[0074] Step S25: If step S24 determines that the transmission is in driving gear, the electronic control unit (VCU) sends a prompt signal to the instrument panel, and the instrument panel flashes multiple times or prompts "Please return to neutral" once.

[0075] Step S26: The electronic control unit (VCU) switches the "Automatic Start Function Driving Ready" signal to the off state. The "Automatic Start Function Driving Ready" signal is abbreviated as the automatic start signal.

[0076] This application uses the above steps S21~S26 to perform a cyclic judgment. The electronic control unit (VCU) judges in real time whether the driver has entered the driver's seat. It combines the driver's seat position with the gear position when the driver has not entered the driver's seat and adjusts the driving position signal of the automatic start function. It has complete closed-loop control capabilities such as on-seat judgment, enable control, off-vehicle closing, and instrument prompts, which improves the safety of the system and the user experience.

[0077] Figure 4 The diagram provided in this application illustrates the process of the driver operating the vehicle to begin the automatic start-up action after the driver's seat function is enabled. (Refer to...) Figure 4 After "Automatic start function driving in position" is enabled, the process for triggering automatic start by the driver is as follows:

[0078] Step S31: The "Automatic start function driving in position" signal is enabled.

[0079] Step S32: The driver performs the starting operation: engages a driving gear, releases the handbrake, and releases the foot brake. The electronic control unit (VCU) obtains the gear position signal through the gear position sensor, the handbrake signal through the handbrake status sensor, and the brake pedal signal through the foot brake status sensor.

[0080] Step S33: When the gear position signal indicates that the vehicle is in driving gear, the handbrake signal indicates that the handbrake is released, and the brake pedal signal indicates that the foot brake is released, the electronic control unit (VCU) generates an automatic start signal and sends it to the transmission control unit (TCU) via CAN communication. After receiving the signal, the TCU controls the engine to increase its speed and torque, and engages the clutch according to a preset engagement rate, controlling the vehicle to enter the automatic start function.

[0081] During the cyclic judgment process of steps S12 to S16 above, the control method provided by this application embodiment has complete closed-loop control capabilities such as on-site judgment, enable control, off-vehicle shutdown, and instrument prompts, which improves the safety of the system and the user experience.

[0082] Based on the same inventive concept, this embodiment provides a control system to prevent the automatic start function of a vehicle from being accidentally activated. Figure 5A block diagram of a control system for preventing accidental vehicle start-up provided in an embodiment of this application, with reference to... Figure 5 The control system for preventing accidental vehicle start-up provided in the application embodiment includes an electronic control unit (VCU) and a transmission control unit (TCU).

[0083] The electronic control unit (VCU) is communicatively connected to the transmission control unit (TCU). The VCU includes a signal acquisition unit 21, a driver positioning determination unit 22, a start-up condition determination unit 23, and a signal output unit 24. The signal acquisition unit 21 acquires door status signals, driver position detection signals, gear position signals, handbrake signals, and brake pedal signals. The driver positioning determination unit 22 is communicatively connected to the signal acquisition unit 21 and determines whether the driver is in the correct position based on the door status signals and driver position detection signals. When the door status signal indicates the door is closed and the driver position detection signal indicates the driver has entered the driver's seat, a driver positioning signal is generated. The start-up condition determination unit 23 is communicatively connected to the signal acquisition unit 21 and the driver positioning determination unit 22. After receiving the driver positioning signal, it determines whether the automatic start-up operation conditions are met based on the gear position signal, handbrake signal, and brake pedal signal. When the gear position signal indicates the vehicle is in a driving gear, the handbrake signal indicates the handbrake is released, and the brake pedal signal indicates the foot brake is released, an automatic start-up signal is generated. The signal output unit 24 is communicatively connected to the start condition determination unit 23 and is used to send the automatic start signal to the transmission control unit TCU to trigger the transmission control unit TCU to control the engine to increase speed and torque, and engage the clutch to control the vehicle to enter the automatic start function.

[0084] In this embodiment of the invention, an electronic control unit (VCU) is used to collect and determine all signals indicating whether the driver is in position and whether the driver is performing operations. This control unit can be a control module, a body control unit, or any other control unit. This control unit can accept hardwired or CAN bus message signals, process the signals, add judgment logic, and send CAN messages to the vehicle communication bus. Exemplarily, the control module can be an integrated circuit (IC), processor, microprocessor, such as a central processing unit (CPU), or other general-purpose processors, digital signal processors (DSPs), application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), or other programmable logic devices, transistor logic devices, hardware components, or any combination thereof.

[0085] Optionally, the signal acquisition unit acquires door status signals, driver presence detection signals, gear signals, handbrake signals, and brake pedal signals via hard-wired signals or CAN communication message signals; the signal output unit sends the automatic start signal to the transmission control unit via CAN communication.

[0086] Optionally, the electronic control unit includes the vehicle control unit or the body control unit.

[0087] Based on the same inventive concept, this invention also provides a vehicle that uses the control method for preventing accidental vehicle start-up provided in the above embodiments to prevent accidental activation of the vehicle's automatic start function.

[0088] The vehicle includes a transmission control unit (TCU), door status sensors, driver presence detection sensors, gear position sensors, handbrake status sensors, foot brake status sensors, and an electronic control unit. The door status sensors detect door status and output a door status signal. The driver presence detection sensor detects whether the driver is in the driver's seat and outputs a driver presence detection signal. The gear position sensor detects the transmission gear and outputs a gear position signal. The handbrake status sensor detects the handbrake status and outputs a handbrake signal. The foot brake status sensor detects the foot brake status and outputs a brake pedal signal.

[0089] The electronic control unit (ECU) communicates with the transmission control unit, door status sensors, driver presence detection sensors, gear position sensors, handbrake status sensors, and foot brake status sensors. The ECU is configured to perform the following operations:

[0090] The driver's positioning is determined based on the door status signal and the driver's presence detection signal. When the door status signal indicates the door is closed and the driver's presence detection signal indicates the driver has entered the driver's seat, a driver's positioning signal is generated. After generating the driver's positioning signal, the automatic start operation conditions are determined based on the gear position signal, handbrake signal, and foot brake signal. When the gear position signal indicates the vehicle is in driving gear, the handbrake signal indicates the handbrake is released, and the foot brake signal indicates the foot brake is released, an automatic start signal is generated. This automatic start signal is sent to the transmission control unit. Upon receiving the automatic start signal, the transmission control unit controls the engine to increase speed and torque, and engages the clutch to control the vehicle to enter the automatic start function. The driver's positioning determination unit is also used for:

[0091] After the driver is in position signal is generated, when the door status signal indicates that the door has switched from the closed state to the open state, or when the driver is in position detection signal indicates that the driver has left the driver's seat, the driver is in position signal is switched to the closed state.

[0092] The control system also includes a prompting unit, which sends a prompting signal to the instrument panel when the driver is in position signal is switched off and the current transmission is in driving gear. The prompting signal is used to instruct the driver to shift the transmission to neutral.

[0093] This invention requires no additional hardware installation and can directly reuse the vehicle's existing electronic control sensing and control architecture, offering significant advantages such as low modification costs, strong adaptability, and fast control response. Under normal starting conditions, the system does not interfere with the driver's routine operations and does not alter the vehicle's existing starting and driving experience. Only in high-risk situations, such as when the driver leaves the vehicle, does it automatically activate specific protection logic to eliminate the risk of unexpected vehicle movement caused by the driver's accidental departure from the electronic control source, effectively improving vehicle safety in scenarios such as driver-vehicle handover and temporary parking. Furthermore, this invention possesses excellent platform adaptability and can be widely applied to fuel vehicles, hybrid vehicles, and pure electric commercial vehicles equipped with automatic start-up functions, meeting the needs of mass production and application.

[0094] Based on the same inventive concept, embodiments of the present invention also provide a storage medium storing a computer program, which, when executed by a processor, implements the control method for preventing accidental vehicle start-up provided in the above embodiments.

[0095] Specifically, the storage medium provided by this invention, when executing the control method for preventing accidental vehicle start-up provided in the above embodiments, can employ any combination of one or more computer-readable media. The computer-readable medium can be a computer-readable signal medium or a computer-readable storage medium.

The computer-readable storage medium can be any tangible medium containing or storing a program that can be used by or in conjunction with an instruction execution system, apparatus, or device.

[0096] Computer-readable signal media may include data signals propagated in baseband or as part of a carrier wave, carrying computer-readable program code. Such propagated data signals may take various forms, including but not limited to electromagnetic signals, optical signals, or any suitable combination thereof. Computer-readable signal media may also be any computer-readable medium other than computer-readable storage media, which can send, propagate, or transmit programs for use by or in connection with an instruction execution system, apparatus, or device.

[0097] Program code contained on a computer-readable medium may be transmitted using any suitable medium, including but not limited to: wireless, wire, optical fiber, radio frequency (RF), etc., or any suitable combination thereof.
