[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] The technical solution disclosed in this application is applicable to automatic transmission vehicles equipped with electronic gear shifters. From a usage perspective, starting the vehicle with the ignition switch is a basic function of the vehicle and is used frequently. However, through research and analysis, the applicant discovered that the operating state of the ignition switch and the operating state of the parking gear (hereinafter referred to as P gear) switch do not conflict. Therefore, this application can reuse the function of the ignition switch on the P gear switch, that is, use the P gear switch as the ignition switch. After users get used to it, the operating efficiency will be improved, and the number of users accepting it will increase. Reducing the number of ignition switches in the entire vehicle saves costs, and at the same time, it allows designers to set more function buttons according to the setting requirements.

[0046] This system starts the vehicle when it is off, provided that the brake pedal is engaged and the Parking (P) switch is activated. For details, see [link to details]. Figure 1 This application discloses a vehicle state control method, which includes steps S101-S104.

[0047] Step S101: Obtain the vehicle start status, brake pedal status, and the triggering method of the parking gear (P gear) switch.

[0048] In this embodiment, the vehicle system can detect the brake pedal status in real time, whether the P-gear switch is triggered, and if so, the triggering method of the P-gear switch. After the brake pedal and / or the P-gear switch is triggered, the vehicle's starting status is detected. In this solution, the vehicle's starting status can include a shut-off state and a starting state. The brake pedal status includes a triggered state and a non-triggered state. The triggered state of the brake pedal refers to the state of the brake pedal when the user presses it down, and the non-triggered state refers to the state of the brake pedal when it is not pressed down. The triggering method of the P-gear switch includes some triggering methods predefined in this application. These triggering methods can be set according to design requirements, such as a tap triggering method and a long press triggering method. Under the tap triggering method and the long press triggering method, based on the number of taps and the duration of the long press, it can be further divided into several different types of triggering methods. By detecting how the user triggers the P-gear switch, the triggering method of the P-gear switch can be further determined.

[0049] Step S102: Determine whether the brake pedal and the P gear switch are triggered simultaneously.

[0050] In this scheme, when the brake pedal and the parking gear (P gear) switch are triggered simultaneously, it indicates that the user has a need to start the vehicle, and step S103 is then executed.

[0051] In this solution, to ensure the user's safe starting of the vehicle, it is necessary to detect whether the brake pedal is depressed when the user starts the vehicle. That is, whether the brake pedal is in a penalized state. Only when the brake pedal is depressed can the user start the vehicle by triggering the P gear switch. Otherwise, the user cannot start the vehicle by triggering the P gear switch. Of course, if the safety of the user and the vehicle is not considered, the brake pedal situation can be ignored, and the user can directly start the vehicle by triggering the P gear switch.

[0052] Step S103: When the brake pedal and the P gear switch are triggered simultaneously, determine whether the vehicle is in a turned-off state.

[0053] In this step, when it is determined that the brake pedal and the P gear switch are triggered at the same time, based on the vehicle's starting state obtained in step S101, it is determined whether the vehicle is in a turned-off state. When the vehicle is in a turned-off state, it indicates that the vehicle has a starting demand. At this time, step S104 is executed.

[0054] Step S104: Start the vehicle.

[0055] In this step, starting the vehicle refers to performing an ignition operation, changing the vehicle from an off state to an on state. During the vehicle starting process, the brake pedal remains in the triggered state, and the vehicle is in either the OFF or ON (engine off) power mode. (In the OFF mode, the vehicle's low-voltage power is cut off; in the ON (engine off) mode, the vehicle's low-voltage power is supplied, and the engine / electric motor does not operate.) After the engine controller (CEM) detects that the automatic transmission controller (TCU) is in the P / N position and the CSA switch (which is part of the CAN bus and network-connected to the CEM) sends a signal to trigger the P switch, the CEM sends a start request signal VehStartReq to the ECM (Engine Electronic Control Module) / HCU (ABS actuator) / VCU (Electronic Control Module). After the ECM / HCU / VCU successfully starts the engine / electric motor, the CEM switches the power mode to the ON (engine run) position, successfully starting the vehicle. In the ON (engine run) mode, the vehicle's low-voltage power is supplied, and the engine and electric motor operate, thus completing the vehicle starting process.

[0056] As can be seen from the above solutions, in the technical solutions disclosed in the above embodiments of this application, when the vehicle is in a turned-off state, the vehicle can be started by operating the brake pedal + P gear switch, without operating the vehicle's start switch. Therefore, there is no need to set up a vehicle start switch in the vehicle, thereby realizing the control of more vehicle functions with fewer functional devices and saving vehicle production costs.

[0057] In the technical solution disclosed in this embodiment, when the vehicle is off, the user can not only start the vehicle by operating the P gear switch, but also control the vehicle to enter the parking state or control the vehicle to shut off when the vehicle is in the starting state by operating the P gear switch. That is, in this solution, when the vehicle is in the starting state and the vehicle speed is 0, when the P gear switch is detected to be triggered, the triggering mode of the P gear switch is obtained, and the vehicle is switched to a state matching the triggering mode. See also Figure 2 This method also includes:

[0058] Step S201: When the vehicle is in the starting state and the vehicle speed is 0, determine whether the P gear switch is triggered.

[0059] In this solution, when the vehicle is in the starting state and the vehicle speed is 0, the detection of the user triggering the P gear switch indicates that the user has a need to start, park, or turn off the vehicle.

[0060] Step S202: If the P-position switch is triggered, obtain the triggering mode of the P-position switch.

[0061] Multiple triggering methods for the P gear switch can be pre-configured. When the user triggers the P gear switch using different triggering methods, the vehicle will be in different states. Therefore, in this step, when the P gear switch is detected to be triggered, it is necessary to analyze the triggering method of the P gear switch.

[0062] Step S203: Switch the vehicle to a state that matches the triggering method.

[0063] In this step, the mapping relationship between the triggering method of the P gear switch and the state that the vehicle needs to switch into can be pre-configured. After determining the triggering method of the P gear switch, the state that the vehicle needs to switch into is determined according to the above mapping relationship, and then the vehicle is switched to that state.

[0064] More specifically, in this solution, when the vehicle is running, if the system detects that the user is operating the P gear switch, the user may need to shift the vehicle into parking, off, or starting mode. Based on these states, this solution categorizes the user's activation of the P gear switch into a first activation method and a second activation method. Depending on the activation method, the vehicle is switched to different states. See [link to solution]. Figure 3 Switching the vehicle to a state matching the triggering method includes:

[0065] Step S301: When the P gear switch is triggered in the first trigger mode, the vehicle's gear status is obtained, and the vehicle is controlled to enter an operating state that matches the gear status.

[0066] In this solution, when the vehicle is running and at a speed of 0, if the user triggers the P-gear switch using the first triggering method, it indicates that the user needs to control the vehicle to park or start the vehicle. Whether the user chooses to park or start the vehicle can be further analyzed based on the vehicle's current gear position. For details, please refer to [link to relevant documentation]. Figure 4 Specific methods include:

[0067] Step S401: Obtain the vehicle's gear status;

[0068] In this solution, the vehicle's gear status is divided into P gear and non-P gear. When the vehicle is in P gear, it indicates that the vehicle is parked, and the user's need for the vehicle is to start. When the vehicle is in non-P gear, it indicates that the vehicle is not parked, and the user's need for the vehicle is to park.

[0069] Step S402: When the vehicle is not in P gear, control the vehicle to enter the parking state.

[0070] When the vehicle is not in P gear, when the user triggers the P gear switch using the first triggering method, it indicates that the vehicle has a parking requirement. At this time, CEM sends the DrvReqPark=0x1:driver request park button command, the user requests to park in P gear, and controls the vehicle to enter the parking state. After the vehicle enters the parking state, the vehicle's gear changes from non-P gear to P gear.

[0071] Step S403: When the vehicle is in P gear, control the vehicle to start.

[0072] When the vehicle is in P gear, it indicates that the vehicle is in a parked state. When the user triggers the P gear switch using the first trigger method, it indicates that the vehicle has a starting demand. CEM sends the command DrvReqPark=0x2:driver requeststart button. At this time, the user can control the vehicle's gear to switch from P gear to a non-P gear, such as a forward or reverse gear. This controls the vehicle to enter the starting state, and the user can control the vehicle to move forward or backward.

[0073] Step S302: When the P gear switch is triggered in the second trigger mode, control the vehicle to enter the engine off state.

[0074] In this step, when the user needs to turn off the engine, the P gear switch can be triggered using the second triggering method. At this time, CEM sends the DrvReqPark=0x3:driver request stop button command to control the vehicle to enter the engine-off state.

[0075] When controlling the vehicle to shut off, the vehicle may be in the ON (engine run) or ON (engine off) power mode. When the CEM detects that the TCU is in the P / N position and the CEM receives a signal from the CSA that the P position switch has been triggered using the second triggering method, the CEM switches the power mode to the OFF position to complete the vehicle shutdown.

[0076] In the technical solution developed in this embodiment, the first triggering method and the second triggering method can be configured according to user needs. For example, the first triggering method can be that the user presses the P switch once; the second triggering method is to press and hold the P switch or press the P switch N times consecutively within a preset duration, where N is a positive integer greater than 1, such as 2 or 3. Here, the preset duration can refer to 1 second or 2 seconds. When pressing and holding the P switch, the duration of the press and hold action is not less than the preset duration, which can refer to 1 second, 2 seconds, or even more than 2 seconds.

[0077] In another embodiment of this application, considering that in some situations, when a user is resting inside the vehicle, there is no need to start the engine or motor, only the low-voltage power supply needs to be controlled to ensure the normal operation of the audio system or other systems. In this case, when the vehicle is off, the user can control the low-voltage power supply by triggering the brake pedal. That is, when the vehicle is off, if the user triggers the brake pedal, the low-voltage power supply state is switched. Specifically, if the user triggers the brake pedal and the vehicle is in a low-voltage power supply state, the vehicle is powered off; otherwise, the vehicle is powered on. When the vehicle is parked, the user can trigger the P-gear switch using a third triggering method. In this case, the vehicle is only off, but will still remain in a low-voltage power supply state. The control scheme disclosed in this embodiment can further meet the user's control needs for the vehicle.

[0078] In another embodiment, when the vehicle is running and at 0 speed, if the user presses and holds the P-gear switch, the vehicle can be turned off first. Even after the engine is off, the vehicle remains in a low-voltage power-on state. If the vehicle switches to the off-engine, low-voltage power-on state and the user continues to press and hold the P-gear switch, the vehicle is powered off, and the low-voltage power is cut off. This control method eliminates the need for the aforementioned third triggering method, making it easier for the user to operate.

[0079] As can be seen from the previous embodiment, in this solution, to facilitate users in controlling the vehicle's status according to their own needs, see [link to previous embodiment]. Figure 5 The complete process of a vehicle starting from a standstill in the above scheme may include:

[0080] Step S501: When the vehicle is off and the speed is 0, check whether the brake pedal is triggered.

[0081] Step S502: When the brake pedal is triggered, control the vehicle system to power on at low voltage.

[0082] In this embodiment, when the vehicle is off, the brake pedal is used as the low-voltage power-on switch for the vehicle system. When the user presses the brake pedal, the vehicle system is powered on at low voltage. At this time, the user can use some functions of the vehicle system, such as audio functions, video playback functions, and lighting functions. That is, when the engine is off and the low voltage is cut off, when the brake pedal is detected to be triggered, the engine controller (CEM) collects the brake pedal high active value, the CEM activates the IG relay and switches the power to the ON position (engine off), at which time the vehicle system is powered on at low voltage, and the whole vehicle meets the requirements for low-voltage electrical use. After the low-voltage power is applied, when the user presses the brake pedal again, the user may have two needs: one is to power off the vehicle, and the other is to start the vehicle. At this time, resetting the brake pedal is used as the trigger condition for cutting off the low-voltage power of the vehicle system. That is, if the user presses the brake pedal and the vehicle has not started before the brake pedal is reset, it indicates that the user needs to control the low-voltage power of the vehicle and should control the power off of the vehicle system. If the vehicle has already started before the brake pedal is reset, it indicates that the user needs to start the vehicle and should not operate on the power-on state of the vehicle system, keeping the power-on state of the vehicle system unchanged.

[0083] Step S503: After the vehicle system is powered on at low voltage, check whether the P-gear switch is triggered.

[0084] When the vehicle system is powered on at low voltage and the brake pedal remains in the triggered state, it is determined whether the P gear switch is triggered. If it is triggered, it indicates that the user needs to start the vehicle. If it is not triggered, it indicates that the user only needs the vehicle system to be powered on and does not need to start the vehicle.

[0085] Step S504: When the P gear switch is triggered, start the vehicle.

[0086] Furthermore, to ensure safe vehicle starting, this solution, upon detecting a brake pedal trigger, further includes: determining whether the vehicle conforms to a preset safe starting strategy. If the vehicle conforms to the preset safe starting strategy, the trigger operation of the brake pedal is responded to, and subsequent processes continue. If the vehicle does not conform to the preset safe starting strategy, the trigger operation of the brake pedal is not responded to. The type of the preset safe starting strategy can be set according to user needs. In the technical solution disclosed in this embodiment, the strategy may at least include: the vehicle key being in a preset area. In this solution, the vehicle key may include a high-frequency key, a low-frequency key, a Bluetooth key, a UWB key, and / or an NFC key. The specific process for determining whether the vehicle key is in the preset area may include: the CEM (Engine Controller) driving a low-frequency antenna to determine whether the high-frequency key is inside the vehicle, and simultaneously detecting whether the Bluetooth key, UWB (Ultra Wide-Band) key, and NFC (Near Field Communication) key are in a valid area inside the vehicle. If the high-frequency key, low-frequency key, Bluetooth key, UWB key, and / or NFC key are detected to be inside the vehicle, it indicates that the vehicle conforms to the preset safe starting strategy.

[0087] In the technical solution disclosed in this embodiment, to prevent the user from being unable to control the vehicle's start or stop due to a malfunction of the P gear switch, a vehicle start switch can be retained for use in case the P gear switch fails. Since the start switch requires a hard-wired switch, it can be placed in the dome light position or on the reading light, sharing a power line with the dome light or reading light. This start switch can be used solely for emergency power-down or emergency power-up. When the CEM detects that the user has pressed the start switch repeatedly (e.g., 3 times or more), it performs an emergency power-down or emergency power-up operation based on the vehicle's current state. For example, if the vehicle is in a starting state or a low-voltage power-on state when the user presses the start switch repeatedly, it is considered that there is an emergency power-up requirement. Based on whether the vehicle meets the preset safe starting strategy, the vehicle can be started. This ensures that the user can start the vehicle in an emergency. Furthermore, to ensure vehicle safety, after an emergency power-down, the vehicle is not allowed to be started again within a specified time (e.g., 3 seconds or more).

[0088] This embodiment discloses a vehicle status control device. For the specific working content of each unit in the device, please refer to the content of the above method embodiment.

[0089] The vehicle state control device provided in the embodiments of the present invention is described below. The vehicle state control device described below can be referred to in correspondence with the vehicle state control method described above.

[0090] See Figure 6 The vehicle status control device disclosed in this application embodiment may include:

[0091] The vehicle status detection unit 10 is used to detect the starting status of the vehicle.

[0092] Brake pedal detection unit 20 is used to detect whether the brake pedal is triggered;

[0093] The parking gear switch detection unit 30 is used to detect whether the P gear switch is triggered.

[0094] The vehicle control unit 40 is used to generate a control signal for starting the vehicle when the vehicle is in a turned-off state, if it detects that the brake pedal is triggered and the P gear switch is triggered.

[0095] When the vehicle control unit 40 detects that the brake pedal and the P gear switch are triggered simultaneously through the brake pedal detection unit 20 and the parking gear switch detection unit 30, it detects whether the vehicle is in a turned-off state through the vehicle status detection unit 10. When the vehicle is in a turned-off state, the vehicle is started. This process can start the vehicle without operating the vehicle's start switch. Therefore, there is no need to install a vehicle start switch in the vehicle, thereby achieving the control of more vehicle functions with fewer functional devices and saving vehicle production costs.

[0096] Furthermore, this application also discloses a vehicle, see [link to application]. Figure 7 The vehicle may include at least one processor 100, at least one communication interface 200, at least one memory 300, and at least one communication bus 400; wherein, the memory 300 and processor 100 can be applied in the vehicle's CEM. In this embodiment of the invention, the number of processor 100, communication interface 200, memory 300, and communication bus 400 is at least one, and the processor 100, communication interface 200, and memory 300 communicate with each other through the communication bus 400; obviously, Figure 7 The communication connections shown for the processor 100, communication interface 200, memory 300, and communication bus 400 are optional.

[0097] Optionally, the communication interface 200 can be an interface of a communication module, such as the interface of a GSM module;

[0098] Processor 100 may be a central processing unit (CPU), an application-specific integrated circuit (ASIC), or one or more integrated circuits configured to implement embodiments of the present invention.

[0099] The memory 300 may include high-speed RAM memory, and may also include non-volatile memory, such as at least one disk storage device.

[0100] Specifically, the processor 100 is used to implement each step disclosed in any of the above-described vehicle state control method embodiments of this application.

[0101] In the technical solution disclosed in this embodiment, when the memory 300 and processor 100 are integrated into the vehicle's CEM, the connection relationship between the CEM and various parts of the vehicle can be found in [reference needed]. Figure 8 As shown, by Figure 8 As can be seen, the CEM is connected to the terminal ECU, CSA switch, ECM, HCU, and VCU via a CAN bus. Figure 8 The brake switch shown is used to send the brake pedal status signal to the CEM. The CSA switch sends the P gear switch trigger signal to the CEM via the CAN bus. The start switch is a conventional vehicle start switch. The difference from the prior art is that this start switch can be set at the dome light position or placed on the reading light, and shares the power line with the dome light or reading light.
