[0059] With the development of electric vehicle technology, there are more and more electronic devices in vehicles, however, during use, electronic devices will inevitably fail, which may cause abnormal vehicle functions, at which time fault repair is needed.

[0060] In the related art, a fault in a vehicle can be cleared by a dedicated fault diagnosis instrument. However, the fault diagnosis instrument can only be operated by a professional, and cannot be operated by a user, which is low in efficiency and poor in user experience.

[0061] Alternatively, the user can also control the vehicle to be powered off to clear the fault. In some examples, a power supply system in the vehicle can be as shown in FIG. 1, which includes a high-voltage battery, a direct current-to-direct current (DC-DC) converter, a vehicle switch, a vehicle controller, an actuator, and a low-voltage battery. The DC-DC converter in the vehicle can convert high-voltage power (such as 200V to 800V) output by the high-voltage battery into low-voltage power (such as 12V or 48V) to supply power to the vehicle switch, the vehicle controller, and the actuator in the vehicle, and to charge the low-voltage battery. When the high-voltage battery in the vehicle is powered off (such as vehicle lock), the low-voltage battery in the vehicle can supply power to the vehicle switch, the vehicle controller, and the actuator in the vehicle. The low-voltage battery can provide power for starting the vehicle.

[0062] The vehicle needs to be powered off, that is, the high-voltage battery and the low-voltage battery (storage battery) of the vehicle are powered off (or referred to as high-voltage and low-voltage power off). In the related art, the user can power off the high-voltage in the vehicle by vehicle locking and the like, but the user needs to use a corresponding tool to pull out the negative power supply of the storage battery of the vehicle to complete the low-voltage power off, which is inconvenient to operate, and plugging in and pulling out the storage battery can cause the storage battery pile head bolt to loosen, resulting in poor contact, and problems such as the vehicle being unable to start.

[0063] To solve the above problems, an embodiment of the present application provides a vehicle control method. In the method, the vehicle can receive an operation from the user, and control the low-voltage power off in the vehicle when the speed of the vehicle and the state of the parking brake system of the vehicle meet the conditions. In this way, the user can control the low-voltage power off of the vehicle by a simple operation when the speed of the vehicle and the state of the parking brake system of the vehicle meet the conditions, which can prevent misoperation of the low-voltage power off, improve the efficiency and accuracy of the low-voltage power off of the vehicle, and improve the user experience.

For example, the vehicle can also include a propulsion system, a memory, a user interface, a steering system, a throttle, a braking unit, a computer vision system, a route control system, an obstacle avoidance system, a wireless communication system, a microphone, and / or a speaker, etc.

[0089] The propulsion system can include components that provide powered movement of the vehicle. For example, the propulsion system can include an engine, an energy source, a transmission, and wheels. The engine can be an electric motor or other type of engine combination. The engine converts the energy source into mechanical energy. Examples of energy sources include solar panels, high-voltage battery modules 202, low-voltage battery modules 203, and other sources of electrical power. The transmission can transmit mechanical power from the engine to the wheels.

[0090] The memory can store data, such as road maps, route information, the vehicle’s location, orientation, speed, and other vehicle data, and other information. Such information can be used by the vehicle during operation in autonomous, semi-autonomous, and / or manual modes. In embodiments of the present application, the memory can be used to store speed information of the vehicle, a state of a parking brake system of the vehicle, and a gear state of the vehicle, etc.

[0091] The user interface can provide information to or receive information from a user of the vehicle. Optionally, the user interface can interact with input / output devices such as the wireless communication system, the microphone, and / or the speaker, etc.

For example, the memory can exist partially or entirely separately from the vehicle. The components described above can be communicatively coupled together in a wired and / or wireless manner.

[0093] Optionally, the components described above are only an example, and in actual applications, components in each module described above can be added or deleted according to actual needs, and FIG. 2 should not be understood as a limitation on embodiments of the present application.

[0094] In some embodiments of the present application, the vehicle can further comprise a hardware structure and / or a software module to implement the above functions in the form of a hardware structure, a software module, or a hardware structure plus a software module. Whether a certain function is implemented in the form of a hardware structure, a software module, or a hardware structure plus a software module depends on the specific application and design constraints of the technical solution.

[0095] The hardware structure of the vehicle and the functions of each part are introduced above. In some examples, as shown in FIG. 3, the present application provides a flowchart of a vehicle control method.

[0096] It should be noted that the method is not limited to the specific order described in FIG. 3 and below. It should be understood that in other embodiments, the order of some steps in the method can be exchanged according to actual needs, or some steps can be omitted or deleted. The method comprises the following steps:

[0097] S301, the vehicle receives a first operation from a user.

[0098] In some examples, the first operation is used to instruct the vehicle to power off under low voltage. Among them, the vehicle power off under low voltage can be the power off of the low-voltage lithium battery in the vehicle.

[0099] In some examples, the first operation can be triggered by the user at least one physical switch; wherein the physical switch can be a physical switch in the vehicle, or can be a physical switch in the vehicle remote key. Alternatively, the first operation can be triggered by the user at least one switch control; wherein the switch control can be a switch control of the display module in the vehicle, or can be a switch control of the display module in the vehicle smart key, wherein the smart key can be a smart device such as a smart phone, a smart watch, etc. Alternatively, the first operation can be triggered by the user at least one switch control and at least one physical switch; or the first operation can be triggered by the user at least one induction switch; the present application does not make specific limitations thereto.

[0100] S302, the vehicle obtains speed information of the vehicle and a state of a parking brake system of the vehicle according to the first operation.

[0101] In some examples, the speed information of the vehicle can be the current driving speed of the vehicle, and the state of the electronic parking brake (EPB) of the vehicle can include a release state, a clamping state, or a fault state.

[0102] The EPB release state can indicate that the EPB does not apply any braking force, and the brake device is in a non-working state (e.g., the brake caliper is in a loosened state), at which time the vehicle can move freely. The EPB clamping state can indicate that the EPB applies a braking force, and the brake device is in a working state (e.g., the brake caliper clamps the brake disc), which can prevent the vehicle from moving. The EPB fault state can indicate that the EPB detects a fault in the vehicle, such as a fault in an electric motor, a sensor, or a circuit in the vehicle, and the EPB enters the fault state.

[0103] It should be understood that the above-mentioned states of the EPB can also include other states, which are not limited in the embodiments of the present application.

[0104] In some examples, the speed information of the vehicle and the state of the parking brake system of the vehicle can be obtained from an intelligent integrated brake system (IPB) in the vehicle.

[0105] In some examples, the vehicle can also obtain the gear state of the vehicle according to the first operation.

[0106] The gear state of the vehicle can include a parking (P) gear state, a neutral (N) gear state, a forward (D) gear state, a reverse (R) gear state, a sport (S) gear state, or a low (L) gear state.

[0107] The P gear state indicates that the drive wheels of the vehicle are locked, and the vehicle cannot move, which is used to lock the transmission when the vehicle is parked to prevent the vehicle from moving. The N gear state indicates that the connection between the engine and the drive wheels of the vehicle is disconnected, and the vehicle can freely roll in the N gear state, but will not be driven by the engine. The D gear state indicates that the vehicle transmission automatically selects the appropriate gear according to the speed of the vehicle during vehicle travel. The R gear state indicates that the vehicle can move backward, which is used for the vehicle to move backward. The S gear state indicates that the vehicle transmission delays gear shifting events during vehicle travel, providing higher engine speed and faster acceleration, which can provide higher performance and response speed. The L gear state indicates that the vehicle transmission remains in a lower gear, which can provide greater engine braking force and traction.

[0108] In some examples, the gear state of the vehicle can be obtained from a switch module of the vehicle.

[0109] For example, when the user triggers the P gear in the vehicle, the switch module can determine that the P gear of the vehicle is in an open state, and the vehicle can obtain the gear state of the vehicle from the switch module of the vehicle as the P gear state.

[0110] In some examples, the gear state of the vehicle can also be obtained from an electronic control unit (ECU) of the vehicle. The embodiments of the present application do not make specific limitations on the method of obtaining the gear state of the vehicle.

[0111] In some examples, the speed information of the vehicle and the parking brake system state of the vehicle are obtained after the vehicle receives the first operation from the user. Alternatively, the speed information of the vehicle and the parking brake system state of the vehicle are periodically obtained. The embodiments of the present application do not make specific limitations thereon.

[0112] S303, the vehicle controls the low-voltage power-off of the vehicle according to the first operation, the speed information of the vehicle, and the parking brake system state of the vehicle.

[0113] In some examples, when the speed of the vehicle is less than the first threshold value and the parking brake system state of the vehicle is in the clamped state, the vehicle is controlled to low-voltage power-off according to the first operation.

[0114] The first threshold value can be user-defined or pre-set in the vehicle. For example, the first threshold value can be 3 km / h, or the first threshold value can be other values, and the embodiments of the present application do not make specific limitations thereon.

[0115] The parking brake system state of the vehicle in the clamped state indicates that the brake device is in the working state (such as the brake caliper clamping the brake disc), which can prevent the vehicle from moving. In this way, when the speed of the vehicle is small and the parking brake system state of the vehicle is in the clamped state, the vehicle is controlled to low-voltage power-off according to the first operation, thereby improving the safety of the low-voltage power-off of the vehicle.

[0116] In some examples, the low-voltage power-off of the vehicle can be to control the MOSFET in the low-voltage lithium battery of the vehicle to be disconnected, and also to disconnect the low-voltage constant power KL30 of the low-voltage battery.

[0117] In this way, the vehicle can control the low-voltage power-off of the vehicle according to the first operation, the speed information of the vehicle, and the parking brake system state of the vehicle.

[0118] In some examples, the vehicle can control the low-voltage power-off and the high-voltage power-off of the vehicle according to the first operation, the speed information of the vehicle, and the parking brake system state of the vehicle. Alternatively, the vehicle receives a second operation from the user, indicating that the vehicle is in a high-voltage power-off state, and then controls the low-voltage power-off of the vehicle according to the first operation, the speed information of the vehicle, and the parking brake system state of the vehicle.

[0119] In this way, when the low-voltage and high-voltage in the vehicle are both powered off, the vehicle completes the power-off and can clear the fault.

[0120] The above embodiments introduce a process of controlling the vehicle to be powered on at low voltage according to the first operation, the speed information of the vehicle, and the state of the parking brake system of the vehicle. In some examples, after the vehicle is powered off at low voltage and high voltage, the vehicle can also control the vehicle to be powered on at low voltage and high voltage. Specifically, it can include S304 and S305 (not shown in FIG. 3) as follows:

[0121] S304, the vehicle receives a low-voltage power-on operation from the user, and controls the vehicle to be powered on at low voltage.

[0122] In some examples, when the high voltage and the low voltage of the vehicle are powered off, the user can trigger the low-voltage power-on switch of the vehicle. After the vehicle receives the low-voltage power-on operation from the user, the vehicle controls the vehicle to be powered on at low voltage.

[0123] For example, as shown in FIG. 4, a low-voltage power-on circuit of the vehicle includes a control module 401, a low-voltage battery module 402, and a low-voltage power-on switch 403. One pin of the low-voltage power-on switch 403 is connected to the ground, and the other pin is connected to the control module 401 and the low-voltage battery module 402.

[0124] In some examples, when the user triggers the low-voltage power-on switch 403 of the vehicle, the low-voltage power-on switch 403 is closed, the low-voltage battery module 402 is grounded, and the low-voltage battery module 402 and the control module 401 receive a digital input signal (DI) to trigger the low-voltage battery module to be powered on, thereby completing the low-voltage power-on, and the low-voltage battery module can supply power to the control module 401 and the like.

[0125] In some examples, the low-voltage power-on switch 403 can be a tailgate switch in the vehicle, or the low-voltage power-on switch 403 can also be another switch in the vehicle. The user triggering the low-voltage power-on switch 403 of the vehicle can be the user triggering the tailgate switch in the vehicle; or the user triggering the tailgate switch in the vehicle for a preset time, for example, the user triggering the tailgate switch in the vehicle for 10s. The embodiments of the present application do not make specific limitations on the specific switch of the low-voltage power-on switch 403 and the way the user triggers the low-voltage power-on switch 403 of the vehicle.

[0126] In some examples, after the vehicle is powered on at low voltage, the low-voltage battery module 402 can supply power to the control module 401, the vehicle start switch (such as a keyless entry and start system), and other devices or systems in the vehicle. When the vehicle receives a high-voltage power-on operation from the user, the vehicle controls the vehicle to be powered on at high voltage.

[0127] S305, the vehicle receives a high-voltage power-on operation from the user, and controls the vehicle to be powered on at high voltage.

[0128] In some examples, the high-voltage power-on operation can include that the user carries the smart key close to the vehicle, the vehicle is automatically unlocked, and the vehicle high-voltage power-on is controlled. Alternatively, the high-voltage power-on operation can include that the user triggers a vehicle unlocking switch in the smart key, the vehicle is automatically unlocked, and the vehicle high-voltage power-on is controlled. Alternatively, the high-voltage power-on operation can include that the user triggers a vehicle start switch, steps on a brake pedal, and the vehicle high-voltage power-on is controlled, and the like. The embodiments of the present application do not make specific limitations in this regard.

[0129] The case that the vehicle controls the vehicle low-voltage power-off according to the first operation, the speed information of the vehicle, and the state of the parking brake system of the vehicle is introduced in S303. The case that the vehicle controls the vehicle low-voltage power-on according to the low-voltage power-on operation is introduced in S304. In some examples, the vehicle can also control the vehicle low-voltage restart according to the first operation, the speed information of the vehicle, and the state of the parking brake system of the vehicle. S303 and S304 can be replaced by S306.

[0130] S306, the vehicle controls the vehicle low-voltage power-off according to the first operation, the speed information of the vehicle, and the state of the parking brake system of the vehicle, and controls the vehicle low-voltage restart after a preset time period.

[0131] The first operation is used to instruct the vehicle to control the vehicle low-voltage power-off, and control the vehicle low-voltage power-on after a preset time period, and complete the vehicle low-voltage restart.

[0132] In some examples, the vehicle controls the vehicle low-voltage power-off according to the first operation, the speed information of the vehicle, and the state of the parking brake system of the vehicle, and controls the vehicle high-voltage power-off. The vehicle can first control the vehicle low-voltage power-off, and then control the vehicle high-voltage power-off. Alternatively, the vehicle can first control the vehicle high-voltage power-off, and then control the vehicle low-voltage power-off. The embodiments of the present application do not make specific limitations in this regard.

[0133] In some examples, after the vehicle controls the vehicle low-voltage power-off, the vehicle can control the vehicle low-voltage power-on after 10s, and complete the vehicle low-voltage restart. Alternatively, after the vehicle controls the vehicle low-voltage power-off and the high-voltage power-off, the vehicle can control the vehicle low-voltage power-on after 10s, and complete the vehicle low-voltage restart.

[0134] The preset time period can be set by the user in advance, or can be pre-stored in the vehicle. The fault problem in the vehicle can be cleared within the preset time. For example, the preset time can be 10s, or the preset time can also be other time. The embodiments of the present application do not make specific limitations in this regard.

[0135] For example, the preset time period is 10s, the vehicle controls the low-voltage power-off and the high-voltage power-off of the vehicle according to the first operation, the speed information of the vehicle and the state of the parking brake system of the vehicle. After the vehicle controls the low-voltage power-off of the vehicle, the vehicle can control the low-voltage power-on of the vehicle after 10s, and complete the low-voltage restart of the vehicle.

[0136] In some examples, the low-voltage power-off of the vehicle can be to control the MOSFET in the low-voltage lithium battery in the vehicle to be disconnected, and also to disconnect the low-voltage constant power KL30 of the low-voltage lithium battery. The low-voltage restart of the vehicle can be to control the MOSFET in the low-voltage lithium battery in the vehicle to be closed after the low-voltage lithium battery in the vehicle is powered off for 10s, and also to restore the low-voltage constant power KL30 of the low-voltage lithium battery.

[0137] In this way, the vehicle controls the low-voltage power-off of the vehicle according to the first operation, the speed information of the vehicle and the state of the parking brake system of the vehicle, and can control the low-voltage restart of the vehicle after the preset time period. After the vehicle is powered off to clear the fault, the basic functions of the vehicle are restored, and the user does not need to operate the vehicle to power on the low-voltage again, thereby improving the user experience.

[0138] The above examples introduce the process of controlling the low-voltage power-off or restart of the vehicle according to the first operation, the speed information of the vehicle and the state of the parking brake system of the vehicle.

[0139] The vehicle needs to power off the high-voltage battery module and the low-voltage battery module in the vehicle. In some examples, the first operation can indicate the high-voltage battery module and the low-voltage battery module in the vehicle to be powered off, complete the high-voltage power-off and the low-voltage power-off of the vehicle, and thus complete the power-off of the vehicle to clear the fault. In some examples, the vehicle can receive the first operation from the user through the switch module, determine the signal corresponding to the first operation, obtain the signal corresponding to the first operation from the switch module, obtain the speed information of the vehicle and the state of the parking brake system of the vehicle according to the signal corresponding to the first operation, and control the low-voltage power-off and the high-voltage power-off of the vehicle according to the signal corresponding to the first operation, the speed information of the vehicle and the state of the parking brake system of the vehicle. As shown in FIG. 5, the specific method can include the following steps:

[0140] S501, the switch module receives the first operation from the user.

[0141] In some examples, the first operation includes controlling the first switch, the brake pedal and the second switch. The first switch can be a physical switch located in the vehicle. For example, the first switch can be a physical switch located on the steering wheel of the vehicle, or the first switch can be a physical switch located on the central control console of the vehicle, or the first switch can be a physical switch located at other positions in the vehicle, and the embodiments of the present application do not make specific limitations thereto. The second switch can be a parking gear switch located in the vehicle.

[0142] Exemplarily, the first switch is a physical switch 601 in a steering wheel of the vehicle as shown in FIG. 6, and the second switch is a parking gear switch.

[0143] In some examples, the first operation can be that the user controls the physical switch 601 in the steering wheel, the brake pedal, and the parking gear switch to be turned on at the same time. For example, the user triggers the physical switch 601 in the steering wheel, steps on the brake pedal, and triggers the parking gear switch at the same time.

[0144] In other examples, the first operation can be that the user controls the physical switch in the steering wheel, the brake pedal, and the parking gear switch to be turned on at the same time and kept for a first preset time. For example, the first operation can be that the user triggers the physical switch 601 in the steering wheel, steps on the brake pedal, and triggers the parking gear switch at the same time and keeps for a first preset time.

[0145] The first preset time can be customized by the user or preset in the vehicle. Exemplarily, the first preset time can be 10 seconds, or the first preset time can be other values, which are not limited in the embodiments of the present application.

[0146] Exemplarily, taking the first preset time of 10 seconds as an example, the first operation can be that the user triggers the physical switch 601 in the steering wheel, steps on the brake pedal, and triggers the parking gear switch at the same time and keeps for 10 seconds.

[0147] In other examples, the first operation can include triggering a third switch.

[0148] The third switch can be a physical switch in the vehicle. For example, the third switch can be a physical switch on the steering wheel, or the third switch can be a physical switch on the central control console of the vehicle, or the third switch can be a physical switch at other positions in the vehicle, which are not limited in the embodiments of the present application.

[0149] In some examples, the first operation can be that the user triggers the physical switch in the vehicle. Alternatively, the first operation can be that the user triggers the physical switch in the vehicle and keeps for a second preset time.

[0150] The second preset time can be customized by the user or preset in the vehicle. Exemplarily, the second preset time can be 5 seconds, or the second preset time can be other values, which are not limited in the embodiments of the present application.

[0151] Exemplarily, taking the second preset time of 5 seconds as an example, the first operation can be that the user triggers the physical switch in the vehicle and keeps for 5 seconds.

[0152] Alternatively, the third switch can be a switch control in the display module. For example, the third switch can be a switch control in a central control display screen (central control screen) of the vehicle. As shown in FIG. 7, it is a central control screen interface 70 of the vehicle, which includes a low-voltage power-off control 701.

[0153] In some examples, the first operation can be that the user triggers the low-voltage power-off control 701.

[0154] In some examples, after the user makes the above-mentioned first operation, the switch module can receive the first operation from the user and determine the signal corresponding to the first operation. Alternatively, the switch module can receive the first operation from the user through the display module and determine the signal corresponding to the first operation. The signal corresponding to the first operation can indicate that the vehicle is powered off at low voltage and high voltage. For example, the signal corresponding to the first operation can be a high-level signal, indicating that the vehicle is powered off at low voltage and high voltage, or the signal corresponding to the first operation can be a low-level signal, indicating that the vehicle is powered off at high voltage and low voltage.

[0155] S502, the control module obtains the signal corresponding to the first operation from the switch module.

[0156] In some examples, the control module obtains a high-level signal from the switch module, indicating that the user makes the first operation, and controls the vehicle to be powered off at low voltage and high voltage. Alternatively, the control module obtains a low-level signal from the switch module, indicating that the user makes the first operation, and controls the vehicle to be powered off at low voltage and high voltage.

[0157] S503, the control module obtains the speed information of the vehicle and the state of the parking brake system of the vehicle according to the signal corresponding to the first operation.

[0158] In some examples, the vehicle can obtain the speed information of the vehicle and the state of the parking brake system of the vehicle from the IPB.

[0159] The speed information of the vehicle and the state of the parking brake system of the vehicle can be obtained as described above in S302, which will not be repeated here.

[0160] In some examples, the vehicle can also obtain the gear state of the vehicle according to the signal corresponding to the first operation. The vehicle can obtain the gear state of the vehicle from the switch module. The gear state of the vehicle can be obtained as described above in S302, which will not be repeated here.

[0161] S504, the control module determines whether to control the vehicle to be powered off at high voltage and to be powered off at low voltage according to the signal corresponding to the first operation, the speed information of the vehicle and the state of the parking brake system of the vehicle. If yes, S505 is executed, and if no, the process is ended.

[0162] In some examples, the signal corresponding to the first operation is the signal corresponding to the operation described in S501, and is used to indicate that the vehicle is powered off at low voltage and powered off at high voltage.

[0163] In some examples, when the speed of the vehicle is less than the preset threshold, and the parking brake system of the vehicle is in the clamped state, the control module can determine to perform S505-S510, to control the vehicle to be powered off at high voltage and powered off at low voltage. When the speed of the vehicle is not less than the preset threshold and / or the parking brake system of the vehicle is not in the clamped state, the control module can end the process.

[0164] In some examples, the control module can further determine whether to control the vehicle to be powered off at high voltage and powered off at low voltage according to the signal corresponding to the first operation, the speed information of the vehicle, the parking brake system state of the vehicle, and the gear state of the vehicle. If yes, S505 is performed, and if no, the process is ended.

[0165] In some examples, when the speed of the vehicle is less than the preset threshold, the parking brake system of the vehicle is in the clamped state, and the gear state of the vehicle is in the parking gear, the control module can determine to perform S505-S510, to control the vehicle to be powered off at high voltage and powered off at low voltage. When the speed of the vehicle is not less than the preset threshold and / or the parking brake system of the vehicle is not in the clamped state and / or the gear state of the vehicle is not in the parking gear, the control module can end the process.

[0166] In this way, the control module can determine whether to perform the vehicle high voltage power off and low voltage power off operation according to multiple information, to prevent the vehicle high voltage power off and low voltage power off operation from being triggered by mistake.

[0167] In some examples, when the control module determines to control the vehicle to be powered off at high voltage and powered off at low voltage, the control module can send a high voltage power off instruction to the high voltage battery module, to instruct the high voltage battery module of the vehicle to be powered off at high voltage, and the high voltage battery module of the vehicle is powered off at high voltage according to the high voltage power off instruction. The control module can also send a low voltage power off instruction to the low voltage battery module, to instruct the low voltage battery module of the vehicle to be powered off at low voltage, and the low voltage battery module of the vehicle is powered off at low voltage according to the low voltage power off instruction. The order in which the vehicle sends the high voltage power off instruction to the high voltage battery module and the low voltage power off instruction to the low voltage battery module is not limited, and the order in which the high voltage battery module is powered off at high voltage according to the high voltage power off instruction and the low voltage battery module is powered off at low voltage according to the low voltage power off instruction is also not limited. For example, it can include S504-S508:

[0168] S505, the control module sends a high voltage power off instruction to the high voltage battery module.

[0169] The high voltage power off instruction is used to control the vehicle to be powered off at high voltage.

[0170] S506, the high-voltage battery module receives the high-voltage power-off instruction and performs high-voltage power-off.

[0171] In some examples, the high-voltage battery module includes a high-voltage system controller, a high-voltage battery control system, a DC-DC converter, and a high-voltage battery. After receiving the high-voltage power-off instruction, the high-voltage system controller can send a power-off message to the high-voltage battery control system and the DC-DC converter, instructing the high-voltage battery control system to control the high-voltage battery to power off, and the DC-DC converter to power off, completing the high-voltage power-off.

[0172] S507, the control module sends a low-voltage power-off instruction to the low-voltage battery module.

[0173] The low-voltage power-off instruction is used to control the vehicle to power off.

[0174] S508, the low-voltage battery module receives the low-voltage power-off instruction and performs low-voltage power-off.

[0175] In some examples, the low-voltage battery module can include a low-voltage battery. Alternatively, the low-voltage battery module can include a low-voltage battery and a vehicle controller. The vehicle controller is used to obtain the low-voltage power-off instruction from the control module and forward or route the low-voltage power-off instruction to the low-voltage battery. The low-voltage battery breaks the MOSFET according to the low-voltage power-off instruction, and the low-voltage constant power KL30 between the low-voltage battery and the vehicle controller is also disconnected accordingly, completing the low-voltage power-off.

[0176] In this way, the control module can control the vehicle to power off according to the signals corresponding to the first operation, the speed information of the vehicle, and the state of the parking brake system of the vehicle.

[0177] In some examples, when the vehicle is controlled to power off, the user can also be reminded that the vehicle is powered off. For example, the control module can remind the user that the vehicle is about to power off through voice reminders, text reminders, etc. For example, S509 and S510 are exemplary methods by which the control module can remind the user that the vehicle is about to power off through text reminders.

[0178] S509, the control module sends a first message to the display module.

[0179] In some examples, the first message can be a message reminding the user that the vehicle is powered off.

[0180] S510, the display module displays the first message.

[0181] In some examples, after receiving the first message from the control module, the display module can display the first message in the first interface.

[0182] For example, the first interface is the central control screen interface 80 of the vehicle as shown in FIG. 8. The interface 80 can include a message (first message) 801 that the vehicle is about to be powered off.

[0183] In this way, when the vehicle is powered off, the vehicle can remind the user that the vehicle is about to be powered off, improving the user experience.

[0184] The above describes an example in which the control module displays the first message through the display module. In other examples, the control module can also play the first message through a speaker or other device, such as playing a message (first message) that the vehicle is about to be powered off through a speaker or other device. To remind the user that the vehicle is about to be powered off. It should be understood that the above control module reminds the vehicle to be powered off through voice, text, and other ways. In embodiments of the present application, the control module can also remind the user that the vehicle is about to be powered off in other ways, which are not limited in embodiments of the present application.

[0185] In this way, after the user makes the first operation, the user can determine that the vehicle is about to be powered off through text prompts or voice prompts, etc., improving the user's experience.

[0186] The above embodiments introduce a first operation to indicate that the high-voltage battery module and the low-voltage battery module in the vehicle are powered off, complete the high-voltage power-off and low-voltage power-off of the vehicle, and thus complete the power-off of the vehicle and the process of clearing the fault. In some examples, a second operation can also be used to indicate that the high-voltage battery module of the vehicle is powered off, and the first operation indicates that the low-voltage battery module of the vehicle is powered off, completes the high-voltage power-off and low-voltage power-off of the vehicle, and thus completes the power-off of the vehicle and the process of clearing the fault.

[0187] In some examples, the vehicle can receive the second operation from the user through the switch module and determine the signal corresponding to the second operation. The control module obtains the signal corresponding to the second operation from the switch module and starts the first mode according to the signal corresponding to the second operation, indicating that the vehicle is in a high-voltage power-off state. Then, the vehicle can receive the first operation from the user through the switch module and determine the signal corresponding to the first operation. The control module obtains the signal corresponding to the first operation from the switch module, obtains the speed information of the vehicle and the state of the parking brake system of the vehicle according to the signal corresponding to the first operation, and controls the vehicle to be powered off according to the signal corresponding to the first operation, the speed information of the vehicle, and the state of the parking brake system of the vehicle. As shown in FIG. 9, the specific method can include the following steps:

[0188] S901, the switch module receives the second operation from the user.

[0189] In some examples, the second operation includes starting the first mode, where the first mode can indicate that the vehicle is in a high-voltage power-off state.

[0190] In some examples, the first mode can be a first mode switch control in a display interface of the display module. The second operation can be that the user triggers the first mode switch control.

[0191] For example, as shown in FIG. 10, the interface 100 of the central control screen of the vehicle includes a first mode switch control 1001. The second operation can be that the user triggers the first mode switch control 1001.

[0192] For example, the first mode can be referred to as a “high-voltage maintenance switch-off mode”. Alternatively, the first mode can also be referred to as other modes, which are not limited in the embodiments of the present application.

[0193] In some examples, after the user performs the second operation, the switch module can obtain the second operation from the user through the display module, and determine a signal corresponding to the second operation. The signal corresponding to the second operation can indicate that the vehicle is powered off.

[0194] In some examples, in order to prevent the user from triggering the second operation by mistake, the vehicle can remind the user to power off the vehicle, or remind the user whether to start the first mode. For example, the vehicle reminding the user whether to start the first mode can include the following S902-S904:

[0195] S902, the switch module sends a second message to the display module.

[0196] In some examples, the second message can be a message reminding the user to power off the vehicle; or the second message can be a message for determining whether the vehicle is powered off.

[0197] S903, the display module displays the second message.

[0198] The second interface includes the second message, and the second message includes a message reminding the user to power off the vehicle or the second message includes a message for determining whether the vehicle is powered off.

[0199] In some examples, after the display module obtains the second message from the switch module, the display module can display the second message in the second interface.

[0200] The second message can include a message reminding the user to power off the vehicle. For example, the second interface is the interface 110 of the central control screen of the vehicle as shown in FIG. 11(a), and the interface 110 can include a message (second message) 1101 reminding the user that the vehicle is about to be powered off.

[0201] Alternatively, the second message includes a message for determining whether the vehicle is powered off. For example, the second interface is the interface 111 of the central control screen of the vehicle as shown in FIG. 11(b), and the interface 111 can include a message (second message) 1102 for determining whether the vehicle is powered off, a “yes” control 1103, and a “no” control 1104.

[0202] In some examples, when the second message comprises a message for determining whether the vehicle is powered off, the following S904 can be performed.

[0203] S904, the switch module receives a third operation from the user.

[0204] In some examples, the third operation can be that the user triggers the "Yes" control 1103 or the "No" control 1104 in (b) of FIG. 11.

[0205] If the third operation is that the user triggers the "Yes" control 1103 in (b) of FIG. 11, the third operation indicates that the vehicle is powered off, S901 is performed, the first mode is started according to the second operation, and it is indicated that the vehicle is in the high-voltage powered-off state.

[0206] In some examples, after the user makes the third operation described above, the switch module can receive the third operation from the user and determine a signal corresponding to the third operation. The signal corresponding to the third operation can indicate high-voltage power-off. For example, the signal corresponding to the third operation can be a high-level signal indicating that the vehicle is high-voltage powered off, or the signal corresponding to the third operation can be a low-level signal indicating that the vehicle is high-voltage powered off.

[0207] S905, the switch module sends a signal corresponding to the third operation to the control module.

[0208] In some examples, the control module obtains a high-level signal from the switch module, indicating that the user makes the third operation, and controls the vehicle to be high-voltage powered off. Alternatively, the control module obtains a low-level signal from the switch module, indicating that the user makes the third operation, and controls the vehicle to be high-voltage powered off.

[0209] In some examples, after the control module obtains the signal corresponding to the third operation from the switch module, the first mode is started, and the vehicle can be controlled to be high-voltage powered off, and the vehicle is in the high-voltage powered-off state. For example, this can specifically include the following S906 and S907:

[0210] S906, the control module sends a high-voltage power-off instruction to the high-voltage battery module according to the signal corresponding to the third operation.

[0211] In some examples, the control module obtains the signal corresponding to the third operation from the switch module and sends a high-voltage power-off instruction to the high-voltage battery module.

[0212] S907, the high-voltage battery module receives the high-voltage power-off instruction and performs high-voltage power-off.

[0213] S905 and S906 can refer to the above-mentioned S505 and S506, and will not be described here.

[0214] Thus, after the control module receives the second operation from the user, the first mode is started, indicating that the vehicle is in a high-voltage powered-off state.

[0215] If the third operation is that the user triggers the "No" control 1104 in (b) of FIG. 11, indicating that the vehicle is not powered off, S901 is not executed, and the flow ends.

[0216] Among them, S902-S905 are optional steps. After the vehicle executes S901, the control module can also start the first mode to control the vehicle to be powered off under high voltage after the control module obtains the signal corresponding to the second operation from the switch module. The vehicle is in a high-voltage powered-off state.

[0217] S908, the switch module receives the first operation from the user.

[0218] In some examples, the first operation includes the user's operation of locking the vehicle.

[0219] For example, the first operation can be that the user locks the vehicle in the vehicle. For example, the first operation can be that the user triggers the vehicle locking control (or vehicle low-voltage powered-off control) in the central control screen. Alternatively, the first operation can be that the user turns on the locking physical switch in the vehicle, and the present application does not make specific limitations to this.

[0220] For another example, the first operation can also be that the user locks the vehicle outside the vehicle. For example, the first operation can be that the user controls the lock switch in the remote key of the vehicle. Alternatively, the first operation can be that the user controls the vehicle locking control in the smart key of the vehicle. Among them, the smart key can be a smart device such as a smart phone, a smart watch, etc. Alternatively, the first operation can be that the user triggers the locking sensing area (such as the locking sensing area at the door handle) in the vehicle, etc., and the present application does not make specific limitations to this.

[0221] In some examples, when the user makes the above-mentioned first operation, the switch module can receive the first operation from the user and determine the signal corresponding to the first operation. The signal corresponding to the first operation can indicate that the vehicle is powered off under low voltage. For example, the signal corresponding to the first operation can be a high-level signal indicating that the vehicle is powered off under low voltage, or the signal corresponding to the first operation can be a low-level signal indicating that the vehicle is powered off under low voltage.

[0222] S909, the control module obtains the signal corresponding to the first operation from the switch module.

[0223] In some examples, the control module obtains a high-level signal from the switch module, indicating that the user makes the first operation to control the vehicle to be powered off under low voltage. Alternatively, the control module obtains a low-level signal from the switch module, indicating that the user makes the first operation to control the vehicle to be powered off under low voltage.

[0224] S910, the control module obtains the speed information of the vehicle and the state of the parking brake system of the vehicle according to the signal corresponding to the first operation.

[0225] The specific content of the control module obtaining the speed information of the vehicle and the state of the parking brake system of the vehicle according to the signal corresponding to the first operation can be referred to S503, and will not be repeated here.

[0226] S911, the control module obtains the speed information of the vehicle and the state of the parking brake system of the vehicle according to the signal corresponding to the first operation to determine whether to control the low-voltage power-off of the vehicle. If yes, S912 is executed, and if not, the process ends.

[0227] In some examples, the control module can also obtain the power-off state of the high-voltage battery from the high-voltage battery module (not shown in the figure). When the high-voltage battery module is in the power-off state, the control module obtains the speed information of the vehicle and the state of the parking brake system of the vehicle according to the signal corresponding to the first operation to determine whether to control the low-voltage power-off of the vehicle.

[0228] In this way, the control module can first control the high-voltage power-off of the vehicle, and then control the low-voltage power-off of the vehicle, prevent the generation of electric arc when the high-voltage battery module is powered off, orderly power off each part in the vehicle, and improve the safety of the vehicle power-off.

[0229] The specific content of the control module obtaining the speed information of the vehicle and the state of the parking brake system of the vehicle according to the signal corresponding to the first operation to determine whether to control the low-voltage power-off of the vehicle can be referred to S504, and will not be repeated here.

[0230] S912, the control module sends a low-voltage power-off instruction to the low-voltage battery module.

[0231] The low-voltage power-off instruction is used to control the low-voltage power-off of the vehicle.

[0232] S913, the low-voltage battery module receives the low-voltage power-off instruction and performs low-voltage power-off.

[0233] The specific process of the low-voltage battery module receiving the low-voltage power-off instruction and performing low-voltage power-off can be referred to S508, and will not be repeated here.

[0234] In this way, the vehicle can control the high-voltage power-off of the vehicle through the second operation, and control the low-voltage power-off of the vehicle through the first operation, so as to complete the power-off of the vehicle and clear the fault in the vehicle.

[0235] In some examples, when the vehicle controls the low-voltage power-off of the vehicle, the user can also be reminded of the power-off of the vehicle. For example, the control module can remind the user that the vehicle is about to be powered off through voice reminder, text reminder, etc. The specific content can include S914 and S915:

[0236] S914, the control module sends a first message to the display module.

[0237] In some examples, the first message can be a message reminding the user that the vehicle is about to be powered off.

[0238] S915, the display module displays the first message.

[0239] Specifically, the control module can remind the user that the vehicle is about to be powered off in the form of a text reminder, as described above in S509 and S510.

[0240] In this way, when the vehicle is powered off, the vehicle can remind the user that the vehicle is about to be powered off, improving the user experience.
