[0029] Embodiment One

[0030] Figure 1 A flow chart of a control method of a vehicle body controller is provided for Embodiment One of the present application. The present application can be applicable to the case of controlling a vehicle body controller. The method can be executed by a control device of the vehicle body controller, which can be realized 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 capability. As shown in the figure, the method comprises: Figure 1

[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 application is applicable to the case of reducing static electricity generated by the vehicle body controller itself, and the technical solution can be executed by the vehicle body controller.

[0033] The serial peripheral interface (SPI) is a synchronous serial communication interface specification, and the communication between the vehicle body controller and the external module can be performed through the SPI. The factory mode reflects that the vehicle in which the vehicle body controller is located is in a production process, that is, the vehicle in which the vehicle body controller is located is not completely assembled in the factory mode. For example, the vehicle body controller can be in the factory mode during the production of the vehicle body controller in the factory and the assembly process in the host factory.

[0034] Specifically, after the production of the vehicle body controller is completed or during the installation of the vehicle body controller in the host factory, if a serial peripheral interface instruction is received, the serial peripheral interface instruction is used to control the vehicle body controller to enter an idle state, and it is determined whether the current operation mode is the factory mode.

[0035] S120, it is determined whether the current operation mode is the factory mode; if yes, S130 is executed; otherwise, S140 is executed.

[0036] Specifically, in a specific example, the vehicle body controller can receive information that the current operation mode is the factory mode before leaving the factory, and then, after receiving the serial peripheral interface instruction, it can be determined that the current operation mode is the factory mode, and then S130 is executed.

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

[0038] S130, the vehicle body controller is controlled to enter a low-power mode to reduce the voltage generated by the static electricity accumulation of the vehicle body controller.

[0039] In the low-power mode, the values of the electrical parameters such as the current and the working power of the vehicle body controller are reduced, that is, lower than those in the idle state, and at this time, the amount of electric charge on the vehicle body controller is reduced, and the high voltage generated by the static electricity is reduced. The power consumption of the vehicle body controller in the low-power mode is less than that in the idle state.

[0040] Specifically, in the factory mode, whether the vehicle body controller is awakened by the external module or a sleep instruction is sent to the vehicle body controller, the vehicle body controller always remains in the low-power mode to reduce the accumulation of electric charge.

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

[0042] Specifically, if the current operation mode is a non-factory mode, the vehicle body controller can be normally used, and enter an idle state to wait for being woken up or being put to sleep in the idle state.

[0043] The technical scheme of the embodiment of the present application comprises: if a serial peripheral interface instruction for controlling the vehicle body controller to enter an idle state is received, it is judged whether the current operation mode is a factory mode; the factory mode reflects that the vehicle where the vehicle body controller is located is in a production process; if yes, the vehicle body controller is controlled to enter a low-power-consumption mode to reduce the voltage generated by static electricity accumulation of the vehicle body controller; otherwise, the vehicle body controller is controlled to enter the idle state; wherein the power consumption of the vehicle body controller in the low-power-consumption mode is less than the power consumption of the vehicle body controller in the idle state. The technical scheme sets the factory mode, so that the vehicle body controller can keep the low-power-consumption mode for a longer time, thereby reducing the high voltage generated by static electricity.

[0044] Embodiment two

[0045] Figure 2 A flow chart of a control method of a vehicle body controller provided by the embodiment two of the present application is provided, and the embodiment of the present application is optimized on the basis of the above-mentioned embodiment.

[0046] As shown in the figure, the method of the embodiment of the present application specifically comprises the following steps: Figure 2

[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, it is judged whether the current operation mode is a factory mode; if yes, S230 is executed; otherwise, S250 is executed.

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

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

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

[0052] ​For example, when the current operating mode is factory mode, the body controller is controlled to enter low power mode. If a sleep command is received, the body controller will remain in low power mode. If a wake-up command for performing certain functions is received, the body controller will remain in low power mode.

[0053] This design ensures that the body controller remains in a low-power mode during factory production (when the vehicle is in the factory), reducing the high voltage generated by static electricity and protecting the body controller.

[0054] S250, controls the body control controller to enter an idle state;

[0055] In low-power mode, the power consumption of the body controller is less than that in idle mode.

[0056] In this embodiment of the application, optionally, the first operating parameter of the body controller in the low-power mode is less than the first operating parameter of the body controller in the idle state, and the second operating parameter of the body controller in the low-power mode is greater than the second operating parameter of the body controller in the 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 low-power mode, the operating current of the body controller is set to 19 microamps, and the operating power of the body controller is set to 2.28 * 10^6 amps. -4 W, the internal crystal oscillator frequency of the body controller is set to 32MHz; in idle state, the operating current of the body controller is set to 6.5mA, and the operating power of the body controller is set to 7.8*10. -2 W, the internal crystal oscillator frequency of the body controller is set to 180kHz.

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

[0059] For example, such as Figure 3 As shown, after the body controller is reset, it can determine whether the current operating mode is factory mode. If so, it enters low power mode (LOW POWER1), and maintains low power mode regardless of whether it is waking up or sleeping while the current operating mode is factory mode. If the current operating mode is not factory mode, it enters idle state (i.e., IDLE). In idle state, if a sleep command is received, it enters low power mode; if a wake-up command is received, it executes the wake-up command.

[0060] Optionally, the method further includes: when the current operation mode is the factory mode, if a notification that the current vehicle has been completely manufactured is received, switching the current operation mode from the factory mode to the non-factory mode.

[0061] Specifically, generally, when the vehicle is in the factory, the current operation mode is the factory mode, and if the vehicle has been completely manufactured, the current operation mode is switched to the non-factory mode.

[0062] Optionally, the method further includes: when the current operation mode is the factory mode, if an emergency wake-up instruction is received, switching the current operation mode to the non-factory mode and executing an emergency task corresponding to the emergency wake-up instruction; and if it is determined that the emergency task is executed, switching the current operation mode to the factory mode.

[0063] For example, in the factory mode, the vehicle body controller is in the low-power consumption mode, at this time, only the emergency wake-up task can temporarily wake up for a period of time, and the vehicle body controller is in the low-power consumption mode at other times, which ensures that the vehicle body controller reduces the influence of static electricity as much as possible and can still handle some unexpected situations.

[0064] Optionally, the method further includes: changing a current value of the MOS current limited on the vehicle body controller to a target value; and the current value is greater than the target value.

[0065] For example, 16A of the MOS current limited on the vehicle body controller is changed to 8A. In this way, the current passing through the MOS is reduced, the MOS is less likely to be damaged, and the vehicle body controller is less likely to be damaged.

[0066] The technical scheme of the embodiment of the application sets the factory mode, so that the vehicle body controller is always in the low-power consumption mode during the production stage in the factory, thereby avoiding the generation of static high voltage and avoiding damage to the vehicle body controller by static electricity, and thus improving the product quality of the vehicle.
