[0055] In order to make the above and other features and advantages of the present application more clear, the present application is further described below in conjunction with the accompanying drawings. It should be understood that the specific embodiments given herein are for the purpose of explaining to those skilled in the art and are only exemplary and not restrictive.

[0056] In the following description, many specific details are set forth to provide a thorough understanding of the present application. However, it will be apparent to one of ordinary skill in the art that specific details are not required to practice the present application. In other cases, well-known steps or services are not described in detail to avoid obscuring the present application.

[0057] Based on the content of the background technology section, it can be known that in the prior art, the operation process of manually controlling the vehicle to start or shut down is too complicated, the probability of operating errors is high, and the safety is poor.

[0058] In order to solve the above technical problems, the present application provides a vehicle power control method, device, electronic device and computer readable storage medium. The vehicle power control method provided by the present application is first described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0059] like Figure 1 As shown, the present application provides a method for controlling a vehicle power supply, which may include:

[0060] Step S11: upon receiving a start-up instruction sent by a mobile terminal, obtaining a first power state of a vehicle power source and a charging state of the vehicle; wherein the charging state of the vehicle includes: a vehicle charging state or a vehicle non-charging state.

[0061] Specifically, in the present application, the power controller can be used as the executive body of the present application. Among them, the power controller can establish a communication relationship with the mobile terminal, the user can issue instructions through the mobile terminal, and then the mobile terminal sends the instructions to the power controller. Among them, the user sends a remote start instruction to the power controller through the mobile terminal, the power controller receives the remote start instruction sent by the mobile terminal, and when receiving the start instruction, obtains the first power state of the vehicle power supply and the charging state of the vehicle. It should be noted that the charging state of the vehicle includes: the vehicle is in a charging state or the vehicle is not in a charging state, that is, whether the vehicle is connected to a charging device (such as a charging gun).

[0062] It should be noted that the power controller may be equipped with a microcontroller chip, which can receive CAN signals, hard-wire signals, etc. to realize intelligent control of vehicle startup or shutdown.

[0063] Step S13: Compare the first power state of the vehicle power supply with the initial power state to generate a first comparison result; wherein the initial power state is used to indicate that the vehicle power supply is in an off state.

[0064] Specifically, in the present application, after the power controller receives the start-up instruction, it is necessary to determine the first power state of the vehicle power supply, that is, to compare the first power state of the vehicle power supply with the initial power state to generate a first comparison result. It should be noted that the initial power state is used to characterize that the vehicle power supply is in the off state.

[0065] Step S15: Compare the charging state of the vehicle with a preset charging state to generate a second comparison result; wherein the preset charging state includes: a state where the vehicle is not charging.

[0066] Specifically, in the present application, after the power controller receives the start command, it is also necessary to determine the charging status of the vehicle, that is, to determine whether the vehicle is connected to a charging device (such as a charging gun), that is, to compare the charging status of the vehicle with the preset charging status to generate a second comparison result; wherein, the preset charging status includes: the vehicle is not charging.

[0067] Step S17: When the first comparison result is that the first power state is consistent with the initial power state, and the second comparison result is that the charging state of the vehicle is consistent with the preset charging state, control the power of the vehicle to be converted from the first power state to the second power state; wherein the second power state is used to characterize that the power of the vehicle is in the on state.

[0068] Specifically, in the present application, the power controller can establish a communication relationship with the power supply. When the power controller determines that the first comparison result is that the first power state meets the initial power state, and the second comparison result is that the charging state of the vehicle meets the preset charging state, the power controller can control the power supply to be converted from the first power state to the second power state. It should be noted that the second power state is used to characterize that the power of the vehicle is in the on state. In other words, when the first power state of the vehicle is that the power of the vehicle is in the off state and the charging state of the vehicle is that there is no charging device (such as a charging gun) connected, the power controller can control the power to turn on, thereby controlling the vehicle to start.

[0069] Compared with the prior art, the present application improves the safety of the vehicle by establishing a communication relationship between the terminal device and the power controller, that is, the power controller receives the start-up instruction and then controls the vehicle power supply through intelligent operation. It solves the technical problem in the prior art that the operation process of manually controlling the vehicle to start or shut down is too complicated, the probability of operating errors is high, and the safety is poor.

[0070] In an optional embodiment, the mobile terminal includes: one or more of an operation background server, a mobile Internet application software, and a remote controller.

[0071] Specifically, in the present application, the mobile terminal may be one or more of an operation background server, a mobile Internet application software, and a remote controller. Among them, the user can send a series of instructions such as a start instruction and a shutdown instruction to the power controller of the vehicle according to the operation background server, the mobile Internet application software, and the remote controller, and then the power controller performs corresponding actions according to the above instructions. For example: when receiving a start instruction, the first power state of the vehicle and the charging state of the vehicle are determined, and then the vehicle is controlled to start or not start according to the first power state of the vehicle and the charging state of the vehicle.

[0072] It should be noted that the remote controller may be a drone remote controller, a remote control key, or other device used for remote control.

[0073] In an optional embodiment, the method further includes: when the first comparison result is that the first power state does not meet the initial power state and / or the second comparison result is that the charging state of the vehicle meets the preset charging state, controlling the vehicle power supply to maintain the first power state.

[0074] Specifically, in the present application, when the power controller determines that the first comparison result does not meet the initial power state and / or the second comparison result is that the charging state of the vehicle meets the preset charging state, the power controller controls the vehicle power to maintain the first power state, that is, when the vehicle is in the on state, the start command is invalid, and when the vehicle is in the charging state, the start command is invalid. When the vehicle is in the on state and the charging state at the same time, the start command is invalid, that is, the vehicle does not start.

[0075] like Figure 2 As shown, in an optional embodiment, after step S17, the method further includes:

[0076] Step S19: When receiving the shutdown command, the running state of the vehicle is obtained; wherein the running state of the vehicle at least includes: a vehicle speed state and a gear state.

[0077] Step S21: Compare the running state of the vehicle with the preset running state to generate a third comparison result; wherein the preset running state includes: a vehicle speed of zero state and a P gear or N gear state.

[0078] Step S23: When the third comparison result shows that the running state of the vehicle meets the preset running state, the second power state is controlled to be converted into the initial power state.

[0079] Specifically, in the present application, the power controller can establish a communication relationship with the vehicle speed sensor and the gear position sensor. Among them, when the vehicle power is in the second power state and the power controller receives a shutdown command, the power controller needs to obtain the operating state of the vehicle, that is, the power controller can obtain the vehicle speed state sent by the vehicle speed sensor, and obtain the gear position state sent by the gear position sensor, and compare the vehicle speed state and the gear position state with the preset operating state respectively. It should be noted that the preset operating state includes: the vehicle speed is zero state and the P gear or N gear state, and a third comparison result is generated. When the third comparison result is that the operating state of the vehicle meets the preset operating state, that is, the gear position state is P gear or N gear, and the vehicle speed is zero, the power controller controls the power supply to be converted from the second power state to the initial power state, that is, the vehicle is turned off (not started).

[0080] It should be noted that when the vehicle speed is not zero and / or the gear position is not P gear or N gear, the power supply is controlled to maintain the second power supply state.

[0081] In an optional embodiment, the method further includes: obtaining a first charging instruction when the vehicle power supply is in a second power supply state;

[0082] Based on the first charging instruction, the running state of the vehicle is obtained; wherein the running state includes: vehicle speed state and gear state.

[0083] The operating state is compared with a preset operating state to generate a fourth comparison result; wherein the preset operating state includes: a vehicle speed zero state and a P gear or N gear state.

[0084] When the fourth comparison result is that the operating state meets the preset operating state, the vehicle power is controlled to be converted from the second power state to the third power state; wherein the third power state is used to represent the charging state of the vehicle power.

[0085] Specifically, in the present application, when the vehicle power supply is in the second power supply state and the vehicle's power supply controller obtains the first charging instruction, the power supply controller obtains the vehicle's operating state, that is, the vehicle speed state and the gear state, according to the first charging instruction, and compares the gear state and the vehicle speed state with the above-mentioned preset operating state to generate a fourth comparison result. When the fourth comparison result is that the operating state is consistent with the preset operating state, the vehicle power supply is controlled to be converted from the second power supply state to the third power supply state; wherein, the third power supply state is used to characterize the charging state of the vehicle power supply.

[0086] In an optional embodiment, if a battery-related fault occurs during the charging process of the vehicle, the power controller controls the power to be converted from the third power state to the initial power state.

[0087] In an optional embodiment, when the vehicle power supply is fully charged and exceeds a first preset time, the vehicle power supply is controlled to be converted from the third power supply state to the initial power supply state.

[0088] Specifically, in the present application, when the vehicle's power supply is fully charged, the full charge is maintained for a first preset time. If no start execution or disconnection instruction is received within the first preset time, the vehicle's power supply is controlled to be converted from the third power state to the initial power state.

[0089] Optionally, the first preset time may be 2 minutes.

[0090] In an optional embodiment, the method further includes: obtaining a second charging instruction when the vehicle power supply is in an initial power supply state.

[0091] Based on the second charging instruction, the vehicle power is controlled to be converted from the initial power state to the third power state.

[0092] When the vehicle power supply is fully charged and exceeds a second preset time or receives a power-off instruction, the vehicle power supply is controlled to be converted from the third power supply state to the initial power supply state.

[0093] Specifically, in the present application, when the vehicle power is in the initial power state and the vehicle power controller obtains a second charging instruction, the power controller controls the vehicle power to transform from the initial power state to the third power state according to the second charging instruction.

[0094] In addition, when the vehicle's power supply is fully charged, the full charge is maintained for a second preset time. If no start-up execution or disconnection instruction is received within the second preset time, the vehicle's power supply is controlled to be converted from the third power supply state to the initial power supply state.

[0095] In an optional embodiment, if a battery-related fault occurs during the charging process of the vehicle, the power controller controls the power to be converted from the third power state to the initial power state.

[0096] Combination Figure 3 and 4 As shown, in an optional embodiment, the present application provides a schematic diagram of a control system for a vehicle power supply.

[0097] The user can send the start-up command or shutdown command issued by the user to the remote receiver through the (tsptelematicsserviceprovider, TSP) remote service according to the administrator application software (Application, APP) and / or the remote monitoring platform, and then the remote receiver sends the start-up command or shutdown command to the central gateway through Ethernet. The central gateway exchanges information and sends the above instructions to the power controller through CAN signals. Then the power controller exchanges information with the vehicle-side controller, sensors and actuators.

[0098] It should be noted that on the vehicle side: the central gateway is used to process Ethernet, CAN network and other signal transmissions; the remote receiver: with a 4G or 5G receiver, receives the wireless signal of the remote operation platform. On the non-vehicle side: the TSP remote service can be a communication base station; the remote monitoring platform can be an operation background server, which can be used to transmit operation instructions to the vehicle side through the server and communication base station; the administrator APP can be a mobile Internet APP software, which can realize mobile terminal functions.

[0099] In an optional embodiment, the present application can also execute the one-button start function of the vehicle, that is, the one-button start function that comes with the vehicle.

[0100] When the vehicle's power controller receives a start command or shutdown command from the one-button start function, the administrator APP, or the remote monitoring platform at the same time, the start command or shutdown command sent by the one-button start function will be executed first. For example, if the one-button start function and the administrator APP send a start command to the power controller at the same time, the start command sent by the one-button start function will be executed first.

[0101] Combined with Table 1 and Figure 5 As shown, in an optional embodiment, the present application provides a flowchart of the conversion conditions of the power state.

[0102] Table 1

[0103] Code Status description C1 Turn on the "One-button start" switch C2 Remote start command (4G or 5G communication encrypted data) C3 Administrator APP startup command (4G or 5G communication encrypted data) C4 Turn off the "One-button start" switch C5 Remote shutdown command (4G or 5G communication encrypted data) C6 Administrator APP shutdown command (4G or 5G communication encrypted data) C7 Speed ​​= 0 km / h C8 P or N C9 Charging gun connection completed C10 Charging gun disconnected C11 Charging is completed and there is no start command for a period of time

[0104] It should be noted that, “OFF” means the OFF power supply (initial power supply state), “ON” means the ON power supply (second power supply state), and “CHG” means the CHG power supply (third power supply state).

[0105] When any one of the conditions (C1 and C10) or (C2 and C10) or (C3 and C10) is met, the initial power state is converted to the second power state; when any one of the conditions (C4 and C7 and C8) or (C5 and C7 and C8) or (C5 and C7 and C8) is met, the second power state is converted to the initial power state.

[0106] When C9 is satisfied, the initial power state is converted to the third power state; when C10 or C11 is satisfied, the third power state is converted to the initial power state.

[0107] When C7, C8 and C9 are satisfied, the third power state is converted into the second power state.

[0108] Combining Table 2 and Figure 6 As shown, in an optional embodiment, the present application provides a schematic diagram of a method for controlling a vehicle power supply.

[0109] Table 2

[0110] Power Status OFF CHG ON CHG relay output × √ √ ON relay output × × √

[0111] 1. Vehicle power-on function (vehicle start)

[0112] (1) One-button start control: When the vehicle is in the OFF position and the charging gun is not connected, the one-button start signal changes from OFF to ON, and the power controller controls the ON position relay / CHG relay coil to energize the vehicle in the ON position.

[0113] (2) Remote start (operation monitoring platform or administrator APP) control: When the vehicle is in the OFF position and the charging gun is not connected, the remote server sends a remote start signal through the wireless network. After the power controller receives the CAN network signal, it controls the ON position relay / CHG relay coil to be energized, so that the vehicle is powered on in the ON position.

[0114] 2. Vehicle power-off function (the vehicle does not start)

[0115] (1) One-button shutdown control: When the vehicle is in the ON gear, the speed = 0 km / h, and the virtual gear signal is P gear, the one-button start switch changes from ON to OFF, and the power controller controls the ON gear relay / CHG relay coil to disconnect, realizing the power-off of the vehicle in the ON gear;

[0116] (2) Remote shutdown control: When the vehicle is in the ON gear, the vehicle speed = 0 km / h, and the virtual gear signal is P gear, the remote server sends a remote shutdown signal through the wireless network. After the power controller receives the CAN network signal, it controls the ON gear relay / CHG relay coil to disconnect, realizing the power-off of the entire vehicle in the ON gear.

[0117] 3. Vehicle charging gear switching function

[0118] (1) OFF position charging: When the vehicle is in the OFF position, connect the charging gun. If there is no battery-related fault in the vehicle, the power controller controls the CHG relay coil to energize, so that the vehicle is powered on in the CHG position and the vehicle starts charging.

[0119] When the vehicle is fully charged, if there is no start command or the charging gun is disconnected for a period of time (2 minutes), the power controller controls the CHG relay coil to disconnect and the vehicle is powered off in CHG gear.

[0120] When a battery-related fault occurs during the vehicle charging process, the power controller controls the CHG relay coil to disconnect and the vehicle is powered off in the CHG gear.

[0121] (2): ON gear charging: When the vehicle is in the ON gear, the speed = 0 km / h, and the virtual gear signal is P gear, connect the charging gun. If the vehicle has no battery-related faults, the power controller controls the ON gear relay coil to disconnect and keep the CHG relay coil energized, so that the vehicle is powered off in the ON gear and switched to the CHG gear, and the vehicle starts charging.

[0122] When the vehicle is fully charged, if there is no start command or the charging gun is disconnected for a period of time (2 minutes), the power controller controls the CHG relay coil to disconnect and the vehicle is powered off in CHG gear.

[0123] When a battery-related fault occurs during the vehicle charging process, the power controller controls the CHG relay coil to disconnect and the vehicle is powered off in the CHG gear.

[0124] It should be noted that the vehicle OFF position can be a state where the vehicle is not started (initial power state), the vehicle ON position can be a state where the vehicle is started (second power state), and the CHG position can be a state where the vehicle is charged (third power state). The ON position relay is used to control whether the vehicle is turned on or off, the CHG relay is used to control whether the vehicle is charged or stopped, and the OFF position relay is used to control whether the vehicle is turned off or not.

[0125] In an optional embodiment, when the vehicle is in the OFF gear, the power controller sends a CAN network signal, which is transmitted to the background server via the wireless network, and the gear status is displayed as OFF; when the vehicle is in the ON gear, the power controller sends a CAN network signal, which is transmitted to the background server via the wireless network, and the gear status is displayed as ON; when the vehicle is in the CHG gear, the power controller sends a CAN network signal, which is transmitted to the background server via the wireless network, and the gear status is displayed as CHG.

[0126] Compared with the prior art, the present application improves the safety of the vehicle by establishing a communication relationship between the terminal device and the power controller, that is, the power controller receives the start-up instruction and then controls the vehicle power supply through intelligent operation. It solves the technical problem in the prior art that the operation process of manually controlling the vehicle to start or shut down is too complicated, the probability of operating errors is high, and the safety is poor.

[0127] In addition, the vehicle can be connected for charging under any power state (such as the initial power state, the second power state, and the third power state), which increases the convenience of user use. In the charging connection state, the vehicle cannot be turned on, thereby ensuring the safety of the vehicle.

[0128] In addition, the present application can send the current power status of the vehicle to the backend server for display, so that the caretaker can monitor it in time.

[0129] like Figure 7 As shown, in an optional embodiment, the present application provides a vehicle power control device, the device comprising: a first acquisition module 71, for acquiring a first power state of the vehicle power and a charging state of the vehicle when receiving a start instruction sent by a mobile terminal; wherein the charging state of the vehicle includes: a vehicle charging state or a vehicle not charging state; a first comparison module 72, for comparing the first power state of the vehicle power with an initial power state to generate a first comparison result; wherein the initial power state is used to characterize that the power of the vehicle is in an off state; a second comparison module 73, for comparing the charging state of the vehicle with a preset charging state to generate a second comparison result; wherein the preset charging state includes: a vehicle not charging state; a first control module 74, for controlling the vehicle power to be converted from the first power state to the second power state when the first comparison result is that the first power state conforms to the initial power state, and the second comparison result is that the charging state of the vehicle conforms to the preset charging state; wherein the second power state is used to characterize that the power of the vehicle is in an on state.

[0130] Specifically, the power controller can be used as the execution subject of this application. Among them, the power controller can establish a communication relationship with the mobile terminal, the user can issue instructions through the mobile terminal, and then the mobile terminal sends the instructions to the power controller. Among them, the user sends a remote start instruction to the power controller through the mobile terminal, and the power controller receives the remote start instruction sent by the mobile terminal, and obtains the first power state of the vehicle power supply and the charging state of the vehicle when receiving the start instruction. It should be noted that the charging state of the vehicle includes: the vehicle is in a charging state or the vehicle is not in a charging state, that is, whether the vehicle is connected to a charging device (such as a charging gun). Among them, after the power controller receives the start instruction, it is necessary to determine the first power state of the vehicle power supply, that is, compare the first power state of the vehicle power supply with the initial power state, and generate a first comparison result. It should be noted that the initial power state is used to characterize that the power of the vehicle is in an off state. Among them, after the power controller receives the start instruction, it is also necessary to determine the charging state of the vehicle, that is, to determine whether the vehicle is connected to a charging device (such as a charging gun), that is, to compare the charging state of the vehicle with the preset charging state, and generate a second comparison result; wherein, the preset charging state includes: the vehicle is not charging state. Among them, the power controller can establish a communication relationship with the power supply. When the power controller determines that the first comparison result is that the first power state meets the initial power state, and the second comparison result is that the charging state of the vehicle meets the preset charging state, the power controller can control the power supply to change from the first power state to the second power state. It should be noted that the second power state is used to characterize that the power of the vehicle is in the on state. In other words, when the first power state of the vehicle is that the power of the vehicle is in the off state and the charging state of the vehicle is that there is no charging device (such as a charging gun) connected, the power controller can control the power to turn on, thereby controlling the vehicle to start.

[0131] Optionally, the device also includes: a second control module, used to control the vehicle power supply to maintain the first power state when the first comparison result is that the first power state does not meet the initial power state and / or the second comparison result is that the charging state of the vehicle meets the preset charging state.

[0132] Specifically, when the power controller determines that the first comparison result does not meet the initial power state and / or the second comparison result is that the charging state of the vehicle meets the preset charging state, the power controller controls the vehicle power to maintain the first power state, that is, when the vehicle is in the on state, the start command is invalid, and when the vehicle is in the charging state, the start command is invalid. When the vehicle is in the on state and the charging state at the same time, the start command is invalid, that is, the vehicle does not start.

[0133] Optionally, the device also includes: a second acquisition module, used to acquire the operating status of the vehicle when a shutdown command is received; wherein the operating status of the vehicle includes at least: a vehicle speed status and a gear status; a third comparison module, used to compare the operating status of the vehicle with a preset operating status to generate a third comparison result; wherein the preset operating status includes: a vehicle speed of zero state and a P gear or N gear state; a third control module, used to control the second power state to be converted into the initial power state when the third comparison result is that the operating status of the vehicle meets the preset operating status.

[0134] Specifically, the power controller can establish a communication relationship with the vehicle speed sensor and the gear sensor. Among them, when the vehicle power is in the second power state and the power controller receives a shutdown command, the power controller needs to obtain the operating state of the vehicle, that is, the power controller can obtain the vehicle speed state sent by the vehicle speed sensor, and obtain the gear state sent by the gear sensor, and compare the vehicle speed state and the gear state with the preset operating state respectively. It should be noted that the preset operating state includes: the vehicle speed is zero state and the P gear or N gear state, and a third comparison result is generated. When the third comparison result is that the operating state of the vehicle meets the preset operating state, that is, the gear state is P gear or N gear, and the vehicle speed is zero, the power controller controls the power supply to be converted from the second power state to the initial power state, that is, the vehicle is turned off (not started).

[0135] Optionally, the device also includes: a third acquisition module, used to acquire the first charging instruction when the vehicle power supply is in the second power supply state; a fourth acquisition module, used to acquire the operating state of the vehicle based on the first charging instruction; wherein the operating state includes: vehicle speed state and gear state; a fourth comparison module, used to compare the operating state with a preset operating state to generate a fourth comparison result; wherein the preset operating state includes: vehicle speed zero state and P gear or N gear state; a fourth control module, used to control the vehicle power supply from the second power supply state to the third power supply state when the fourth comparison result is that the operating state meets the preset operating state; wherein the third power supply state is used to characterize the charging state of the vehicle power supply.

[0136] Specifically, when the vehicle power is in the second power state and the vehicle's power controller obtains the first charging instruction, the power controller obtains the vehicle's operating status, that is, the vehicle speed status and the gear status, according to the first charging instruction, and compares the gear status and the vehicle speed status with the above-mentioned preset operating status to generate a fourth comparison result. When the fourth comparison result is that the operating status meets the preset operating status, the vehicle power is controlled to be converted from the second power state to the third power state; wherein the third power state is used to characterize the charging state of the vehicle power.

[0137] Optionally, the device further includes: a fifth control module, configured to control the vehicle power supply to be converted from a third power supply state to an initial power supply state when the vehicle power supply is fully charged and exceeds a first preset time.

[0138] Specifically, when the vehicle power is fully charged, the full charge is maintained for a first preset time. If no start execution or disconnection instruction is received within the first preset time, the vehicle power is controlled to be converted from the third power state to the initial power state.

[0139] Optionally, the device also includes: a fifth acquisition module, used to acquire a second charging instruction when the vehicle power supply is in an initial power state; a sixth control module, used to control the vehicle power supply to be converted from the initial power state to the third power state based on the second charging instruction; and a seventh control module, used to control the vehicle power supply to be converted from the third power state to the initial power state when the vehicle power supply is fully charged and exceeds a second preset time or receives a power-off instruction.

[0140] Specifically, when the vehicle power is in the initial power state and the vehicle power controller obtains the second charging instruction, the power controller controls the vehicle power to be converted from the initial power state to the third power state according to the second charging instruction.

[0141] In addition, when the vehicle's power supply is fully charged, the full charge is maintained for a second preset time. If no start-up execution or disconnection instruction is received within the second preset time, the vehicle's power supply is controlled to be converted from the third power supply state to the initial power supply state.

[0142] Optionally, the mobile terminal includes: one or more of an operation background server, a mobile Internet application software, and a remote controller.

[0143] Specifically, the mobile terminal may be one or more of an operation background server, a mobile Internet application software, and a remote controller. Among them, the user can send a series of instructions such as a start instruction and a shutdown instruction to the power controller of the vehicle according to the operation background server, the mobile Internet application software, and the remote controller, and then the power controller performs corresponding actions according to the above instructions. For example: when receiving a start instruction, the first power state of the vehicle and the charging state of the vehicle are determined, and then the vehicle is controlled to start or not start according to the first power state of the vehicle and the charging state of the vehicle.

[0144] Compared with the prior art, the present application improves the safety of the vehicle by establishing a communication relationship between the terminal device and the power controller, that is, the power controller receives the start-up instruction and then controls the vehicle power supply through intelligent operation. It solves the technical problem in the prior art that the operation process of manually controlling the vehicle to start or shut down is too complicated, the probability of operating errors is high, and the safety is poor.
