[0060] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0061] Combine the following Figures 1 to 7 The present invention is described. First, reference is made to Figure 1 and Figure 4 , a pure electric vehicle electric control method of the present invention comprises:

[0062] S100: In response to a door unlocking signal, generating a first unlocking instruction and recording an unlocking duration, wherein the unlocking signal is generated by a remote control key or a terminal device, and the first unlocking instruction is used to control the door unlocking;

[0063] S110: When the unlocking duration is within a preset time range and it is detected that the main driving door is opened, a power-on process is executed;

[0064] Alternatively, S200: detecting a key signal in response to a brake pedal signal;

[0065] S210: When the key signal exists and passes the verification, the power-on process is executed.

[0066] In the scenario where the user is outside the car, in response to the door unlock signal generated by the user through the remote control key or the terminal device, a first unlock instruction is generated to unlock the door, and the unlock duration is recorded. When the user opens the main driving door within the preset time range, it means that the user needs to use the car, and the power-on process is executed. Or, in the scenario where the user is inside the car, in response to the brake pedal signal, and when the key signal that has passed the verification is detected, that is, when there is a legal key in the car, it means that the user needs to use the car, and the power-on process is executed. In this way, there is no need to rely on the physical structure of the start button. Based on the user's car usage habits in different scenarios outside and inside the car, the power-on process is intelligently executed, which is conducive to improving the user experience, and the power-on is controlled by generating a door unlock signal and stepping on the brake pedal in different ways, that is, providing multiple power-on control methods. Even if one of the methods fails, the user can still try to achieve power-on control in another way, which is conducive to improving the reliability of power-on control.

[0067] When the vehicle is not powered on, it is in the vehicle low power consumption (KL OFF) state, and the high-voltage electrical modules such as the motor are turned off. In the KL OFF state, the electronic steering column lock is usually locked to prevent the vehicle's steering wheel from turning and prevent the vehicle from being stolen.

[0068] In the KL OFF state, the body control module in the pure electric vehicle mainly maintains basic operation at low voltage, thereby controlling the operation of doors, lights, windows and other components. In some embodiments of the electric control method of a pure electric vehicle of the present invention, the execution subject may be the body control module, and in other embodiments, other modules or additional special modules may be used as the execution subject.

[0069] The door unlock signal can be generated by the remote control key paired with the vehicle, or by the terminal device used by the user, such as a mobile phone, tablet computer, etc., through an application. The remote control key can generate a wireless key signal, and by verifying the key signal, it can be determined whether the remote control key is a legal key matched with the vehicle.

[0070] In the scenario where the user is outside the car, the user operation generates a door unlock signal, which may be due to the need to use the car or the desire to take items from the car. In the case of taking items from the car, there is no need to power on. Therefore, after responding to the door unlock signal, the unlock duration is recorded. If the unlock duration is within the preset time range, that is, the user opens the main driving door within the preset time range after unlocking, it means that the user is likely to need to use the car and the power-on process is executed; if the front passenger door, rear seat door, trunk door, etc. are opened, it means that the user is likely to take items and no power is required.

[0071] In the scenario where the user is in the car, the user may be resting in the car or waiting for passengers, etc., and when the car is needed, according to the safe car use habits, the user first needs to step on the brake pedal. At this time, in response to the generated brake pedal signal, it is detected whether there is a key signal that passes the inspection, that is, whether there is a legal key in the car, and when a legal key exists, the power-on process is executed.

[0072] Different control strategies are adopted for scenarios in different user locations to achieve convenient and intelligent automatic power-on control of pure electric vehicles, making it more convenient for users to use and improving user experience.

[0073] In some embodiments of the present invention, the preset time range may be within 30 seconds, that is, after the user generates a door unlocking signal through operation, if the user opens the main driving door within 30 seconds, it is considered that the user needs to use the car and the power-on process is executed.

[0074] refer to Figure 4 In some embodiments of the electric control method of a pure electric vehicle of the present invention, in S110 and S210, the power-on process includes:

[0075] Controls the unlocking of the electronic steering column lock;

[0076] Control the IGN relay to energize and switch to the vehicle electrical activation state;

[0077] Detect brake pedal signal and key signal;

[0078] When the key signal exists, the key signal passes verification, and the brake pedal signal is continuously greater than a first preset time threshold, detecting gear position information and vehicle speed information;

[0079] When the gear information meets the preset gear condition and the vehicle speed information meets the preset vehicle speed condition, a power-on request message is generated and transmitted to the vehicle controller, so that the vehicle controller switches to the vehicle preparation state when it is determined that the preset preparation condition is met.

[0080] When executing the power-on process, the electronic steering column lock is controlled to be unlocked so that the user can turn the steering wheel normally, and the IGN relay is controlled to be energized so that the on-board electrical modules in the vehicle can obtain power, so that the vehicle switches from the KL OFF state to the electrical activation (KL ON) state. When switching to the KL ON state, the on-board electrical modules such as the body control module (BCM), the electronic gear shift module (EGSM), the wheel control and braking module (WCBS) and the vehicle control unit (VCU) will be powered on for self-test to automatically check the working status of the vehicle. After the self-test is completed and there is no major fault problem, if the user continues to step on the brake pedal for more than the first preset time threshold and there is a legal key in the vehicle, the gear information and the vehicle speed information are further detected to determine whether the preset gear condition and the preset vehicle speed condition are met respectively. If both are met, a power-on request message is sent to the vehicle control unit. When the vehicle control unit determines that the working status of the vehicle meets the preset preparation condition, the vehicle switches from the KL ON state to the ready (READY) state. When the vehicle is in the READY state, the user can drive the vehicle to move.

[0081] In this way, after switching to the KL ON state, the user can start the vehicle to switch to the READY state by continuously stepping on the brake pedal for more than the first preset time threshold, completing the power-on process without relying on the start button, making operation more convenient.

[0082] The IGN (Ignition) relay is mainly responsible for controlling the power switch of the on-board electrical module. When the IGN relay is energized, the on-board battery supplies power to the on-board electrical module to switch to the KL ON state. When the IGN relay is disconnected, the on-board electrical module loses power and switches to the KL OFF state. It is understandable that when the IGN relay is disconnected, not all on-board electrical modules will lose power. For example, the body control module can obtain power from the auxiliary low-voltage power supply to maintain key functions such as locking and unlocking the vehicle.

[0083] In some embodiments of the present invention, the preset gear condition may be the parking gear (P gear) or the neutral gear (N gear), and the preset vehicle speed condition may be the vehicle speed is less than or equal to 5 kilometers per hour, or may be other conditional parameters.

[0084] refer to Figure 4 In some embodiments of the electric control method of a pure electric vehicle of the present invention, the controlling the unlocking of the electronic steering column lock comprises:

[0085] generating a power supply instruction, wherein the power supply instruction is used to instruct a power supply source to supply power to the electronic steering column lock;

[0086] Obtaining identity authentication information generated by the electronic steering column lock;

[0087] generating a verification result according to the identity verification information and transmitting the verification result to the electronic steering column lock;

[0088] Acquiring verification success information generated by the electronic steering column lock, generating a second unlocking instruction and transmitting the second unlocking instruction to the electronic steering column lock;

[0089] The unlocking completion information generated by the electronic steering column lock is acquired, and a power-off instruction is generated, wherein the power-off instruction is used to instruct a power supply source to stop supplying power to the electronic steering column lock.

[0090] The electronic steering column lock does not require power when it is in a maintained state, such as maintained locked or maintained unlocked. Therefore, when it is necessary to switch the state, the electronic steering column lock needs to be powered first and pass the identity authentication process. The electronic steering column lock verifies the legitimacy of the identity, that is, after the verification is successful, it is allowed to switch the state according to the instruction. During the power-on process, the electronic steering column lock is switched to the unlocked state, and then the power supply of the electronic steering column lock is disconnected to maintain the unlocked state.

[0091] It is understandable that during the power-off process, it is a similar process. It is necessary to first supply power to the electronic steering column lock, and then after identity verification, send a command to switch the electronic steering column lock to a locked state. Then, disconnecting the power supply of the electronic steering column lock can maintain the locked state, thereby preventing the vehicle from being stolen and improving safety.

[0092] refer to Figure 2 and Figure 5 In some embodiments of the electric control method of a pure electric vehicle of the present invention, after executing the power-on process, the method further includes:

[0093] S300: generating a first locking instruction in response to a locking signal, wherein the locking signal is generated by a remote control key or a terminal device, and the first locking instruction is used to control the locking of a vehicle door;

[0094] S310: Obtain door status information, and when the door status information meets a preset door closing condition, execute a first power-off process.

[0095] After the user finishes using the vehicle, the vehicle door will be locked. In response to the locking signal, the body control module generates a first locking instruction to control the door locking, obtains the door status information, checks whether the door status meets the preset door closing condition, and executes the first power-off process when the preset door closing condition is met.

[0096] In this way, there is no need to rely on the start button. Users can generate a locking signal by locking the car after using it according to their car usage habits, and intelligently execute the first power-off process, making it more convenient to use and improving the user experience.

[0097] The locking signal is generated by the remote control key matched to the vehicle, or by a terminal device used by the user, such as a mobile phone, tablet computer, etc., through an application.

[0098] In some embodiments of the present invention, the preset door closing condition may be that the main driving door, the front passenger door, the two rear doors and the trunk door are all closed, that is, the five doors of the vehicle are closed. When the user locks the vehicle and the five doors of the vehicle are closed, the first power-off process is automatically executed. In other embodiments of the present invention, when the vehicle has only the main driving door, the front passenger door and the trunk door, the preset door closing condition may be that three doors are closed.

[0099] If it is determined based on the door status information that a door is not closed, a prompt instruction may be generated, and the prompt instruction controls prompt devices such as lights, horns, etc. to prompt the user that a door is not closed.

[0100] refer to Figure 5 In some embodiments of the electric control method of a pure electric vehicle of the present invention, in S310, the execution of the first power-off process includes:

[0101] Detect gear information, vehicle speed information and over-the-air upgrade mode information;

[0102] When the gear information satisfies a preset gear condition, the vehicle speed information satisfies a preset vehicle speed condition, and it is determined according to the air upgrade mode information that the vehicle is in a non-air upgrade mode, a power-off request message is generated and the power-off request message is transmitted to a vehicle controller, so that the vehicle controller executes a high-voltage release process and switches to a vehicle electrical activation state;

[0103] Detect high voltage release status information and charging status information;

[0104] When it is determined according to the high-voltage release state information that the high-voltage release is completed and it is determined according to the charging state information that the vehicle is in a non-charging state, the IGN relay is controlled to be disconnected and the vehicle is switched to a low-power consumption state;

[0105] Controls the electronic steering column lock.

[0106] When the gear information, vehicle speed information, and over-the-air upgrade mode information all meet the required conditions, the body control module sends a power-off request message to the vehicle controller to enable the vehicle controller to execute the high-voltage release process, safely release the high-voltage power supply, and switch from the READY state to the KL ON state. After the high-voltage release is completed according to the high-voltage release state information, and when it is determined to be in a non-charging state according to the charging state information, the IGN relay is controlled to disconnect and switch from the KL ON state to the KL OFF state. Then the electronic steering column lock is controlled to switch to the locked state to prevent vehicle theft and improve safety.

[0107] Over-the-air (OTA) updates allow for remote updates of the vehicle's multimedia interactive module's software, maps and other data. When in over-the-air mode, you can wait for the update to be completed and switch to non-over-the-air mode before continuing the power-off process.

[0108] When the vehicle is in charging state, the battery management module needs to cooperate, so it needs to be maintained in the KL ON state.

[0109] refer to Figure 3 , Figure 6 and Figure 7 In some embodiments of the electric control method of a pure electric vehicle of the present invention, after executing the power-on process, the method further includes:

[0110] S400: In response to a power-off signal, recording a signal duration, wherein the power-off signal is generated by an in-vehicle multimedia interaction module;

[0111] S410: When the duration of the signal is less than a second preset time threshold, executing a second power-off process;

[0112] S420: When the signal duration is greater than or equal to the second preset time threshold, executing a third power-off process.

[0113] In addition to intelligently executing the first power-off process by generating a locking signal, users can also generate a power-off signal by operating the on-board multimedia interaction module, such as clicking on the corresponding power icon on the vehicle's central control touch screen. According to the signal duration of the power-off signal, when it is less than the second preset time threshold, the second power-off process is executed; when it is greater than or equal to the second preset time threshold, the third power-off process is executed.

[0114] In this way, there is no need for the physical structure of the start button, allowing the user to achieve power-off control by operating the on-board multimedia interaction module, which is easy to use. At the same time, combined with the method of generating a locking signal to achieve power-off control, it is possible to provide multiple power-off control methods. Even if one of the methods fails, the user can still try to achieve power-off control in another way, which is conducive to improving the reliability of power-off control.

[0115] By executing different power-off processes according to the signal duration of the power-off signal, when the signal duration is greater than or equal to the second preset time threshold, the third power-off process executed can be a forced power-off process, so that forced power-off can be achieved when needed, thereby improving safety of use.

[0116] In some embodiments of the present invention, the second preset time threshold may be 3 seconds.

[0117] refer to Figure 6In some embodiments of the electric control method of a pure electric vehicle of the present invention, in S410, the execution of the second power-off process includes:

[0118] Detect gear information and vehicle speed information;

[0119] When the gear information satisfies a preset gear condition and the vehicle speed information satisfies a preset vehicle speed condition, a power-off request message is generated and the power-off request message is transmitted to a vehicle controller, so that the vehicle controller executes a high-voltage release process and switches to a vehicle electrical activation state;

[0120] Detect high voltage release status information and charging status information;

[0121] When it is determined according to the high-voltage release state information that the high-voltage release is completed and it is determined according to the charging state information that the vehicle is in a non-charging state, the IGN relay is controlled to be disconnected and the vehicle is switched to a low-power consumption state;

[0122] Controls the electronic steering column lock.

[0123] The second power-off process is to operate the vehicle multimedia interaction module to turn off, and the power-off signal generated is triggered, that is, the vehicle multimedia interaction module enters the off state, so there is no need to obtain the air upgrade mode information for judgment. According to the gear information and the vehicle speed information, it is judged whether the preset gear condition and the preset vehicle speed condition are met respectively. When both conditions are met, a power-off request information is generated to enable the vehicle controller to execute the high-voltage release process, safely release the high-voltage power supply, and switch from the READY state to the KL ON state. After the high-voltage release is completed according to the high-voltage release state information, and when it is determined to be in a non-charging state according to the charging state information, the IGN relay is controlled to disconnect and switch from the KL ON state to the KL OFF state. Then the electronic steering column lock is controlled to switch to the locked state to prevent the vehicle from being stolen and improve safety.

[0124] refer to Figure 7 In some embodiments of the electric control method of a pure electric vehicle of the present invention, in S420, the execution of the third power-off process includes:

[0125] Detect gear information and vehicle speed information;

[0126] When the gear information satisfies a preset gear condition and the vehicle speed information satisfies a preset vehicle speed condition, a power-off request message is generated and the power-off request message is transmitted to a vehicle controller, so that the vehicle controller executes a high-voltage release process and switches to a vehicle electrical activation state;

[0127] Keep the IGN relay energized.

[0128] The user can perform the third power-off process to force the power off by long pressing the corresponding power logo in the vehicle's central control touch screen, etc., so that the signal duration of the power-off signal is greater than or equal to the second preset time threshold. When executing the third power-off process, the gear information and the vehicle speed information are used to determine whether the preset gear condition and the preset vehicle speed condition are met. When both conditions are met, a power-off request message is generated to instruct the vehicle controller to execute the high-voltage release process, safely release the high-voltage power supply, and switch from the READY state to the KL ON state. At this time, the IGN relay is kept energized and the KL ON state is maintained. In this way, when the on-board multimedia interaction module is unresponsive or other situations require forced power off, forced power off can be achieved, thereby improving the safety of use.

[0129] In some embodiments of the electric control method of a pure electric vehicle of the present invention, the controlling the electronic steering column lock to be locked includes:

[0130] generating a power supply instruction, wherein the power supply instruction is used to instruct a power supply source to supply power to the electronic steering column lock;

[0131] Obtaining identity authentication information generated by the electronic steering column lock;

[0132] generating a verification result according to the identity verification information and transmitting the verification result to the electronic steering column lock;

[0133] Acquire verification success information generated by the electronic steering column lock, generate a second locking instruction and transmit the second locking instruction to the electronic steering column lock;

[0134] The locking completion information generated by the electronic steering column lock is acquired, and a power-off instruction is generated, wherein the power-off instruction is used to instruct a power supply source to stop supplying power to the electronic steering column lock.

[0135] During the power-off process, power is first supplied to the electronic steering column lock, and then after identity authentication, a command is sent to switch the electronic steering column lock to a locked state. The power supply to the electronic steering column lock is then disconnected to maintain the locked state, thereby preventing the vehicle from being stolen and improving safety.

[0136] refer to Figures 4 to 7 The present invention also provides a pure electric vehicle, including a body control module (BCM), an electronic steering column lock (ESCL), an electronic gear shift module (EGSM), a wheel control and braking module (WCBS) and a vehicle controller (VCU), wherein the body control module, the electronic steering column lock, the wheel control and braking module and the vehicle controller cooperate to implement the above-mentioned pure electric vehicle electronic control method.

[0137] In the scenario where the user is outside the car, the body control module responds to the door unlock signal generated by the user through the remote control key or the terminal device, generates a first unlock instruction to unlock the door, and records the unlock duration. When the user opens the main driving door within the preset time range, it means that the user needs to use the car, and the body control module, the electronic steering column lock, the wheel control and brake module, and the vehicle controller cooperate to execute the power-on process. Or, in the scenario where the user is inside the car, in response to the brake pedal signal, and the presence of a verified key signal is detected, that is, when there is a legal key in the car, it means that the user needs to use the car, and the body control module, the electronic steering column lock, the wheel control and brake module, and the vehicle controller cooperate to execute the power-on process. In this way, there is no need to rely on the physical structure of the start button. Based on the user's car usage habits in different scenarios outside and inside the car, the power-on process is intelligently executed, which is conducive to improving the user experience, and the power-on is controlled by generating a door unlock signal and stepping on the brake pedal in different ways, that is, providing multiple power-on control methods. Even if one of the methods fails, the user can still try to achieve power-on control in another way, which is conducive to improving the reliability of power-on control.
