[0029] Embodiment 1

[0030] Figure 1 A flow chart of a control method of a vehicle body controller is provided for the first embodiment of the present application. The embodiment of the present application is applicable to the case of controlling a vehicle body controller. The method can be executed by a control device of the vehicle body controller. The control device of the vehicle body controller can be implemented in the form of hardware and / or software. The control device of the vehicle body controller can be configured in an electronic device with data processing capabilities. Figure 1 As shown, the method includes:

[0031] S110 , if a serial peripheral interface instruction for controlling the vehicle body controller to enter an idle state is received, S120 is executed.

[0032] The technical solution of the embodiment of the present application is suitable for reducing the static electricity generated by the body controller itself, and the technical solution can be executed by the body controller.

[0033] Among them, the serial peripheral interface (Serial Peripheral Interface, SPI) is a synchronous serial communication interface specification, when the body controller and the external module communicate, it can be carried out through SPI. The factory mode reflects that the vehicle where the body controller is located is in the production process, that is, in the factory mode, the vehicle where the body controller is located has not been fully assembled. For example, the body controller can be in factory mode in the factory that produces the body controller and in the assembly process of the main engine factory.

[0034] Specifically, after the body controller is produced, or during the process of being installed in the vehicle by the OEM, if a serial peripheral interface instruction is received, and the serial peripheral interface instruction is used to control the body controller to enter an idle state, it is determined whether the current operating mode is the factory mode.

[0035] S120, determining whether the current operation mode is the factory mode; if so, executing S130; otherwise, executing S140.

[0036] Specifically, in a specific example, before leaving the factory, the body controller may receive information that the current operating mode is the factory mode, and then after receiving the serial peripheral interface instruction, it may determine that the current operating mode is the factory mode, and then execute S130.

[0037] In another specific example, the vehicle has been manufactured, and the body controller receives an instruction that the current operation mode is a non-factory mode. When the serial peripheral interface instruction is received again, it can be determined that the current operation mode is a non-factory mode, and then S140 is executed.

[0038] S130, controlling the vehicle body controller to enter a low power consumption mode to reduce a voltage generated by static electricity accumulation in the vehicle body controller.

[0039] Among them, in low power mode, the values ​​of electrical parameters such as current and working power of the body controller will be reduced, that is, lower than the idle state. At this time, the amount of charge on the body controller will be reduced, which can reduce the high voltage generated by static electricity. The power consumption of the body controller in low power mode is less than that in the idle state.

[0040] Specifically, in the factory mode, no matter the external module wakes up the body controller or sends a sleep command to the body controller, the body controller always maintains a low power consumption mode to reduce charge accumulation.

[0041] S140, controlling the vehicle body controller to enter an idle state.

[0042] Specifically, if the current operation mode is non-factory mode, the vehicle body controller can be used normally and enters an idle state to wait to be awakened or put into sleep in the idle state.

[0043] The technical solution of the embodiment of the present application includes: if a serial peripheral interface instruction for controlling the body controller to enter an idle state is received, then determine whether the current operation mode is a factory mode; the factory mode reflects that the vehicle where the body controller is located is in the production process; if so, control the body controller to enter a low power mode to reduce the voltage generated by the static electricity accumulation of the body controller; otherwise, control the body controller to enter an idle state; wherein the power consumption of the body controller in the low power mode is less than the power consumption of the body controller in the idle state. By setting the factory mode, the technical solution allows the body controller to maintain a low power mode for a longer period of time, thereby reducing the high voltage generated by static electricity.

[0044] Embodiment 2

[0045] Figure 2 This is a flow chart of a control method of a vehicle body controller provided in Embodiment 2 of the present application. Embodiment of the present application is optimized based on the above embodiment.

[0046] like Figure 2 As shown, the method of the embodiment of the present application specifically includes the following steps:

[0047] S210 , if a serial peripheral interface instruction for controlling the vehicle body controller to enter an idle state is received, S220 is executed.

[0048] S220, determining whether the current operation mode is the factory mode; if so, executing S230; otherwise, executing S250.

[0049] The factory mode reflects that the vehicle in which the body controller is located is in the production process;

[0050] S230, controlling the vehicle body controller to enter a low power consumption mode to reduce a voltage generated by static electricity accumulation in the vehicle body controller.

[0051] S240, when the current operation mode is the factory mode, if a sleep command or a wake-up command is received, the body controller is controlled to maintain a low power consumption mode.

[0052] Exemplarily, when the current operating mode is the factory mode, the body controller is controlled to enter a low power consumption mode. If a sleep command is received at this time, the low power consumption mode is still maintained; if a wake-up command for executing certain functions is received, the body controller is still controlled to maintain a low power consumption mode.

[0053] This solution is configured so that the body controller is always in low power consumption mode in factory mode (the vehicle is in the factory production stage), reducing the high voltage generated by static electricity in the body controller and protecting the body controller.

[0054] S250, controlling the vehicle body controller to enter an idle state;

[0055] Among them, the power consumption of the body controller in the low power consumption mode is less than the power consumption of the body controller in the idle state.

[0056] In an embodiment of the present application, optionally, a first operating parameter of the body controller in low power consumption mode is less than a first operating parameter of the body controller in idle state, and a second operating parameter of the body controller in low power consumption mode is greater than a second operating parameter of the body controller in idle state; the first operating parameter includes: operating current and operating power; the second operating parameter includes: internal crystal oscillator frequency.

[0057] For example, in the low power mode, the operating current of the body controller is set to 19 microamperes, and the operating power of the body controller is set to 2.28*10 -4 W, the internal crystal frequency of the body controller is set to 32Mh; in idle state, the working current of the body controller is set to 6.5 mA, and the working power of the body controller is set to 7.8*10 -2 W, the internal crystal frequency of the body controller is set to 180Khz.

[0058] S260, when the current operation mode is non-factory mode, if a sleep command is received, the body controller is controlled to enter a low power consumption mode; if a wake-up command is received, the body controller is controlled to execute a wake-up task corresponding to the wake-up command.

[0059] For example, Figure 3 As shown, after the body controller is reset, it can be determined whether the current action mode is the factory mode. If so, it enters the low power mode (LOW POWER1), and when the current operation mode is the factory mode, it remains in the low power mode regardless of wake-up or sleep. If the current operation mode is not the factory mode, it enters the idle state (i.e., IDLE). In the idle state, if a sleep command is received, it enters the low power mode; if a wake-up command is received, the wake-up command is executed.

[0060] In the embodiment of the present application, optionally, the method further includes: when the current operating mode is the factory mode, if a notification is received that the current vehicle has been offline, switching the current operating mode from the factory mode to the non-factory mode.

[0061] Specifically, usually, when the vehicle is in a factory, the current operating mode is the factory mode. If the vehicle has been completed, the current operating mode is switched to the non-factory mode.

[0062] In an embodiment of the present application, optionally, the method also includes: when the current operating mode is the factory mode, if an emergency wake-up instruction is received, the current operating mode is switched to the non-factory mode, and the emergency task corresponding to the emergency wake-up instruction is executed; if it is determined that the emergency task is completed, the current operating mode is switched to the factory mode.

[0063] For example, in factory mode, the body controller is in low power consumption mode. At this time, only the emergency wake-up task can temporarily wake up the body controller for a period of time. The rest of the time, the body controller is in low power consumption mode. This setting ensures that the body controller can reduce the impact of static electricity as much as possible while still being able to handle some unexpected situations.

[0064] In an embodiment of the present application, optionally, the method further includes: changing a current value of the MOS current limit on the vehicle body controller to a target value; the current value is greater than the target value.

[0065] Exemplarily, the 16 A limiting MOS current on the vehicle body controller is changed to 8 A. This arrangement of the present solution reduces the current passing through the MOS, making the MOS less susceptible to damage, and thus making the vehicle body controller less susceptible to damage.

[0066] The technical solution of the embodiment of the present application sets a factory mode so that the body controller always maintains a low power consumption mode during the vehicle production stage in the factory, thereby avoiding the generation of high static electricity voltage and preventing the body controller from being damaged by static electricity, thereby improving the product quality of the entire vehicle.
