Description

Technical Field

[0001] This application belongs to the field of vehicle technology, and in particular relates to a vehicle starting method, device, vehicle terminal and vehicle. Background Technology

[0002] With the upgrading of car configurations, the starting method of traditional gasoline vehicles has changed from rotary start to push-button one-button start. With push-button one-button start, the user can start the vehicle by pressing the start switch.

[0003] However, in traditional gasoline-powered vehicles, the push-button start switch is a mechanical component. If the push-button start switch malfunctions, the gasoline-powered vehicle will not start. Summary of the Invention

[0004] In view of this, embodiments of this application provide a vehicle starting method, device, vehicle terminal, and vehicle to enable quick vehicle starting and avoid the inability to start the vehicle when the one-button start switch malfunctions.

[0005] A first aspect of this application provides a vehicle starting method, the vehicle including an intelligent start and entry system, the method comprising:

[0006] Determine whether the vehicle meets the starting conditions in the current vehicle mode, the starting conditions including receiving a start trigger signal triggered by a brake signal and finding the smart key of the vehicle;

[0007] If the vehicle meets the starting conditions, the power relay is activated and authentication is performed with the engine management system.

[0008] When the engine management system receives a signal indicating successful authentication, a start request is sent to the engine management system to enable the engine management system to start the vehicle.

[0009] A second aspect of this application provides a vehicle starting device, the vehicle including an intelligent start and entry system, the device comprising:

[0010] The determination module is used to determine whether the vehicle meets the start conditions in the current vehicle mode, the start conditions including receiving a start trigger signal triggered by a brake signal and finding the smart key of the vehicle;

[0011] An authentication module is used to control the power relay to engage and authenticate with the engine management system if the vehicle meets the starting conditions.

[0012] The startup module is used to send a startup request to the engine management system when it receives a signal indicating that the engine management system has passed authentication, so that the engine management system can start the vehicle.

[0013] A third aspect of this application provides an in-vehicle terminal, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the method described in the first aspect above.

[0014] A fourth aspect of this application provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the method described in the first aspect above.

[0015] A fifth aspect of this application provides a computer program product that, when run on an in-vehicle terminal, causes the in-vehicle terminal to execute the method described in the first aspect above.

[0016] A sixth aspect of this application provides a vehicle that can be started using the vehicle starting method described in the first aspect above.

[0017] Compared with the prior art, the embodiments of this application have the following advantages:

[0018] In this embodiment, the user can trigger vehicle start by braking. The vehicle has multiple vehicle modes, and the triggering method for vehicle start differs in each mode. The vehicle start trigger signal can be triggered by braking. When the vehicle receives a start trigger signal triggered by braking in the current vehicle mode and the vehicle's smart key is detected, it can be determined that the vehicle meets the start conditions in the current vehicle mode. At this time, the smart start and entry system can control the power relay to engage and authenticate with the engine management system. If the smart start and entry system receives an authentication pass signal from the engine management system, it can send a start request to the engine management system. After receiving the start request, the engine management system starts the vehicle, thus completing the quick start of the vehicle. In this embodiment, the user can start the vehicle by braking, thereby avoiding the problem of not being able to start the vehicle when the one-button start switch malfunctions mechanically; it also eliminates the need for a one-button start switch in the vehicle, achieving quick start. Furthermore, in this embodiment, different start trigger signals can be used in different vehicle modes; the vehicle can have a simple start trigger signal in working mode; a complex start trigger signal in factory mode; and it cannot start in maintenance mode. By using different start-up trigger signals corresponding to different modes, the vehicle can be prevented from starting due to accidental activation during maintenance or assembly, thus avoiding danger.

[0031] The technical solution of this application will be described below through specific embodiments.

[0032] Reference Figure 1 The diagram illustrates a step-by-step flowchart of a vehicle starting method according to an embodiment of this application, which may specifically include the following steps:

[0033] S101, determine whether the vehicle meets the start conditions in the current vehicle mode, the start conditions include receiving a start trigger signal triggered by a brake signal and finding the smart key of the vehicle.

[0034] The execution subject in this embodiment is the vehicle terminal, specifically the Passive Entry Passive Start (PEPS) system in the vehicle.

[0035] The vehicle modes mentioned above can include factory mode and work mode. Vehicles are in factory mode during assembly in the workshop, and also when they first leave the factory. After the vehicle leaves the factory and has been started, it can be switched to work mode.

[0036] The aforementioned start-up trigger signal is a signal that triggers intelligent start and enters the system to start the vehicle. In this embodiment, the start-up trigger signal can be generated based on the brake signal.

[0037] In factory mode, a start-up trigger signal is generated when the brake is applied a preset number of times within a preset time. For example, in factory mode, if a user presses the brake pedal twice within one second, it can be determined that the user needs to start the vehicle, and a corresponding start-up trigger signal is generated. In factory mode, the start-up trigger signal needs to be generated by pressing the brake pedal multiple times within a preset time, thus preventing the vehicle from starting due to accidental brake application and avoiding potential dangers.

[0038] In operating mode, when the vehicle is not running, detecting any one of the braking signals will generate a corresponding start-up trigger signal. For example, a user can start the vehicle by pressing the brake pedal once. The brake can include two hard-wired signals. The intelligent start and entry system can collect both hard-wired braking signals. In operating mode, the intelligent start and entry system only needs to detect one hard-wired braking signal to determine and generate a start-up trigger signal. The start-up trigger signal in operating mode can be easily triggered by braking, thus enabling quick vehicle start-up.

[0039] Figure 2 This is a schematic diagram of the hardware composition of a vehicle according to an embodiment of this application. Figure 2As shown, the intelligent start and entry system can be connected to the brake switch, hazard light switch, fuel filler cap, hood, low-frequency antenna, power relay, multimedia host (HUT), engine management system (EMS), and anti-lock braking system (ABS). The intelligent start and entry system can be physically connected to the brake switch, hazard light switch, fuel filler cap, hood, low-frequency antenna, and power relay via hard wiring, allowing it to obtain the status of these devices. The intelligent start and entry system can also be connected to the multimedia host, engine management system, and ABS via Controller Area Network (CAN), enabling information exchange with these systems.

[0040] The aforementioned brake switch can be a brake switch. The intelligent start and entry system is connected to the brake via a physical bus, allowing it to detect in a timely manner whether the brake has been triggered. The intelligent start and entry system can determine whether the vehicle has been triggered based on its current vehicle mode and the detected brake signal.

[0041] The aforementioned starting conditions also include a smart key, which can be used to verify the user's identity. Only the user with the smart key can start the vehicle, thus preventing theft. The smart start and entry system is connected to a low-frequency antenna, which can then drive the antenna to search for the smart key.

[0042] If the smart start and entry system determines that the current vehicle has been triggered by a start signal and that the smart key has been found, the smart start and entry system can determine that the vehicle meets the start conditions and can start the vehicle.

[0043] In one possible implementation, the vehicle mode described above may also include a maintenance mode. When the vehicle is sent for maintenance, the maintenance personnel can switch the vehicle to maintenance mode via the vehicle's multimedia host. In maintenance mode, the vehicle cannot be started, thereby preventing injury to the maintenance personnel due to accidental starting during the maintenance process.

[0044] The multimedia head unit may have input devices, such as a touchscreen, through which users can configure vehicle settings. The smart start and entry system connects to the multimedia head unit and can receive user-configured vehicle information, thereby adjusting the vehicle's operating mode.

[0045] S102, if the vehicle meets the starting conditions, the power relay is controlled to engage and authenticate with the engine management system.

[0046] Because the smart start and entry system is connected to both the power relay and the engine management system, it can control the power relay to engage. Once engaged, the smart start and entry system can authenticate with the engine management system. It can send a key to the engine management system, which can then authenticate the system based on that key.

[0047] S103, when the engine management system receives a signal indicating that the engine management system has passed authentication, a start request is sent to the engine management system to enable the engine management system to start the vehicle.

[0048] If the engine management system returns an authentication success signal to the intelligent start and entry system, it indicates that the authentication between the intelligent start and entry system and the engine management system is successful. At this point, the intelligent start and entry system can send a start request to the engine management system. Upon receiving the start request, the engine management system can start the vehicle.

[0049] In this embodiment, when the one-button start switch malfunctions mechanically, the user can quickly start the vehicle by braking. Different vehicle modes require different braking signals to trigger the start signal, thus meeting different needs in different situations and avoiding the dangers of braking while driving.

[0050] Reference Figure 3 This illustration shows a flowchart of another vehicle starting method provided in an embodiment of this application, which may specifically include the following steps:

[0051] S301, determine whether the vehicle meets the starting conditions in the current vehicle mode, the starting conditions including receiving a start trigger signal triggered by a brake signal and finding the smart key of the vehicle.

[0052] S301 in this embodiment is similar to S101 in the previous embodiment and can be referenced accordingly, so it will not be described again here.

[0053] S302, detect the current state of multiple components in the vehicle.

[0054] The aforementioned components may include Figure 2 The components shown include: engine cover, fuel filler cap, power relay, engine management system, etc.

[0055] During vehicle startup, after determining that the vehicle meets the starting conditions, it's also necessary to check whether several individual components of the vehicle meet the starting requirements. For example, before starting the vehicle, the hood and fuel filler cap must be closed; otherwise, it could pose a danger. Before starting the car, the power relay and engine management system must be in a fault-free state to ensure the vehicle starts normally.

[0056] Since the intelligent start and entry system can be connected to the refueling cap, engine cover, and power relay via physical hardwires, it can detect the status of the refueling cap, power relay, and engine cover via these physical hardwires.

[0057] The intelligent start and entry system can be connected to the engine management system via a fieldbus. Therefore, the intelligent start and entry system can determine whether the engine management system is malfunctioning via the fieldbus.

[0058] S303, based on the current state of the plurality of components, determine whether the vehicle meets the start-up requirements.

[0059] If the fuel filler cap is closed, the power relay is functioning properly, the engine hood is closed, and the engine management system is functioning properly, then the vehicle can be confirmed to meet the starting requirements.

[0060] S304, if the vehicle meets the starting conditions and the vehicle meets the starting requirements, then the power relay is controlled to engage and authenticate with the engine management system.

[0061] If the vehicle does not meet the starting conditions or requirements, it will fail to start. In this case, the multimedia head unit can alert the user to the reason why the vehicle cannot start. For example, if the car is in maintenance mode and cannot start, the intelligent start and entry system can send a message to the multimedia head unit stating "Vehicle cannot start in maintenance mode," which will be displayed on the multimedia head unit's screen. If the fuel filler cap or hood is open, or if the starting failure occurs within one minute of the engine being turned off, the intelligent start and entry system will separately prompt the multimedia head unit with messages such as "Fuel filler cap is open, please close the fuel filler cap," "Hood is open, please close the hood," or "Please try starting the vehicle again in one minute." The multimedia head unit will then display the received information on its screen.

[0062] S305, when the engine management system receives a signal indicating that the engine management system has passed authentication, a start request is sent to the engine management system to enable the engine management system to start the vehicle.

[0063] S304-S305 in this embodiment are similar to S102-S103 in the previous embodiment and can be referenced accordingly, so they will not be described in detail here.

[0064] S306, when a long press command is received for the hazard light switch, the power relay is disconnected to turn off the vehicle.

[0065] If the vehicle brakes fail and the engine needs to be turned off in an emergency, the user can turn off the vehicle by pressing and holding the hazard light switch.

[0066] The intelligent start and entry system is connected to the hazard light switch and can detect user commands via the hazard light switch. When the intelligent start and entry system receives a long press command for the hazard light switch, it can disconnect the power relay, thus turning off the vehicle.

[0067] Therefore, the hazard light switch can be placed in a hard-to-reach location, such as the roof area, to avoid accidental triggering that could cause the vehicle to stall.

[0068] S307, the timer starts when the vehicle is turned off.

[0069] To prevent accidental restarting of the vehicle due to accidental braking after the engine is turned off, a timer needs to be started each time the vehicle is turned off. The vehicle can only be started after the timer has finished.

[0070] S308, before the preset time has elapsed, it is determined that the vehicle does not meet the start-up conditions.

[0071] The preset duration can be set freely, for example, to 1 minute. Before the preset duration is reached, the intelligent start and entry system will determine that the vehicle does not meet the start conditions.

[0072] The intelligent start and management system will only allow the vehicle to start after the preset time has elapsed.

[0073] In one possible implementation, the vehicle may also include a keyless start switch. Through the multimedia host, the user can configure the vehicle's starting method, determining whether it is keyless start or quick start. If the user selects quick start, the intelligent start and entry management system can start the vehicle according to the method described in this embodiment. When the keyless start switch malfunctions, the vehicle can directly switch to quick start and start using the method described in this embodiment. When the vehicle stalls abnormally during driving, the starting method can be switched back to keyless start.

[0074] In this embodiment, before starting the vehicle, it is necessary to check whether multiple parts of the vehicle meet the starting requirements. Starting can only proceed when the vehicle meets the starting conditions and requirements. This prevents hazards caused by vehicle components not reaching a safe state. In this embodiment, an emergency engine shutdown can be achieved by pressing and holding the hazard light switch, and the vehicle is not allowed to be restarted for a preset time after shutdown, ensuring driving safety.

[0075] It should be noted that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0076] To better illustrate this solution, a specific embodiment is provided below to describe the solution in this application.

[0077] In this embodiment of the application, in order to achieve wireless matching of the in-vehicle engine electronic anti-theft system (ECU) and ensure the accuracy of the connection, a wireless transmitter needs to be placed at a fixed location on the vehicle production line. At the same time, the vehicle also needs to carry a wireless transmitter and receiver. The wireless transmitter and receiver can use UWB nodes.

[0078] The vehicle supports two starting methods: one-button start and the quick start method implemented in this application. The vehicle's starting method can be set via the multimedia host.

[0079] Vehicles need to be assembled and tested in the workshop before they can leave the factory. Vehicles are in factory mode when they first leave the factory.

[0080] When the vehicle is started using quick start and is in factory mode:

[0081] The prerequisites for starting the vehicle are: the engine management system is fault-free; the multimedia host is not set to vehicle maintenance mode; the fuel filler cap is closed; the power relay is fault-free; and the engine hood is closed.

[0082] The vehicle is started by pressing the brake pedal twice within 1 second.

[0083] The specific execution process for vehicle starting is as follows: the intelligent start and entry system drives the low-frequency antenna to search for the smart key; after the smart key is found, the intelligent start and entry system determines that the engine management system is fault-free, the multimedia host is not set to vehicle maintenance mode, the fuel filler cap is closed, and the power relay is fault-free; then the intelligent start and entry system controls the power relay to activate and enters the authentication process with the engine management system. After receiving the authentication pass signal from the engine management system, the intelligent start and entry system sends a start request signal to the engine management system; subsequently, the engine management system controls the engine to start after receiving the start request signal from the intelligent start and entry system.

[0084] If any conditions are not met during the above process, the intelligent start and entry system will prompt the instrument panel that the start conditions are not met. If the start failure is caused by the vehicle being in maintenance mode, the fuel filler cap being open, or the hood being open, the intelligent start and entry system will separately prompt the instrument panel with "The vehicle cannot be started in maintenance mode" or "The fuel filler cap is open, please close the fuel filler cap".

[0085] When a vehicle is in factory mode, and the factory has updated the anti-theft data for the smart start and entry system, and the vehicle has already been successfully started in factory mode, the vehicle can switch from factory mode to working mode.

[0086] When the intelligent start and entry system receives a factory mode exit command from the diagnostic tool, it can execute the exit command. The specific execution process is as follows: the intelligent start and entry system sends a signal to the multimedia host that the intelligent start and entry system will enter the working mode, please confirm; then, after the vehicle user clicks the confirmation button on the instrument panel, the multimedia host sends a confirmation command to the intelligent start and entry system; after that, the intelligent start and entry system exits the factory mode and enters the working mode.

[0087] The intelligent start and entry system uses quick start as its starting method. In working mode, the prerequisites for starting the vehicle are: the engine management system is fault-free; the multimedia host is not set to vehicle maintenance mode; the fuel filler cap is closed; the power relay is fault-free; it is not within the 1-minute countdown of being powered off; and the brake switch is fault-free.

[0088] The vehicle starts when any valid braking signal is detected.

[0089] The vehicle starting process is as follows: The intelligent start and entry system drives the low-frequency antenna to search for the smart key; after finding the smart key, the intelligent start and entry system determines that the engine management system is fault-free, the multimedia host is not set to vehicle maintenance mode, the fuel filler cap is closed, and the power relay is fault-free; then the intelligent start and entry system controls the power relay to activate and enters the authentication process with the engine management system. After receiving the authentication pass signal from the engine management system, the intelligent start and entry system sends a start request signal to the engine management system; after receiving the start request signal from the intelligent start and entry system, the engine management system controls the engine to start.

[0090] The intelligent start and entry system can display a message on the multimedia host indicating that the starting conditions are not met. If the starting failure is due to being in maintenance mode, with the fuel filler cap or hood open, or within one minute of the engine being turned off, the intelligent start and entry system will separately display a message on the instrument panel stating "Vehicle cannot be started in maintenance mode," "Fuel filler cap is open, please close the fuel filler cap," or "Please try starting the vehicle again in one minute."

[0091] When a vehicle is brought to a repair shop, it can be put into maintenance mode via the multimedia system before repairs are performed. In maintenance mode, the vehicle is prohibited from starting.

[0092] Since the vehicle is started by pressing the brake pedal, in order to prevent the vehicle from starting abnormally due to accidentally pressing the brake pedal, a 1-minute timer needs to be started every time the vehicle is turned off. The vehicle is only allowed to start after the 1-minute timer has ended.

[0093] In quick start mode, since there is no one-button start switch, to enable emergency engine shutdown in case of brake failure, the vehicle can be shut off by pressing and holding the hazard light switch for 3 seconds. The prerequisite for emergency shutdown is that the engine is currently running. The trigger action for emergency shutdown is: pressing and holding the hazard light switch for 3 seconds. The execution process for emergency shutdown is: intelligent start and entry system disconnects the power relay, and starts a 1-minute timer.

[0094] If the vehicle stalls unexpectedly while driving, the restart method can automatically switch to one-button start.

[0095] In one possible implementation, to avoid the vehicle being unable to start frequently due to mechanical failure of the keyless start switch or to reduce the frequent operation steps during the start-up process, the keyless start switch can be omitted.

[0096] In this embodiment, considering the situation of vehicles in workshop production, intelligent start-up and entry include a factory mode. In factory mode, the vehicle is started by pressing the brake twice within 1 second, thereby avoiding accidental starting of the vehicle during workshop assembly. To prevent abnormal engine starting by pressing the brake in case of engine failure, this embodiment determines whether the engine is faulty when starting the vehicle. In this embodiment, the vehicle mode can also be set through the multimedia host, so that users can switch between different vehicle modes in different situations.
