[0074] It should be understood that when the vehicle high voltage request flag bit is set and the BMS high voltage relay request state is "attracted", the vehicle ready first flag bit is set, otherwise it is reset.

[0075] Step S202, when the motor actual working mode is torque mode, and the motor three level fault flag bit is reset, the vehicle ready second flag bit is set.

[0076] It can be understood that when the motor actual working mode is "torque mode" (i.e. torque mode), and the motor three level fault flag bit is reset, the vehicle ready second flag bit is set, otherwise it is reset.

[0078] It can be understood that when the PEPS start button request is an up ready request, the gear is a P gear (i.e., a parking gear), the brake pedal state is "pressed down" (i.e., a brake state), the vehicle speed validity flag is positioned, the fast charging gun connection flag is reset, the slow charging gun connection flag is reset, the V2L discharge gun connection flag is reset, and the V2V discharge gun connection flag is reset, the third vehicle ready flag is positioned, otherwise it is reset.

[0079] Step S204, when the battery temperature is greater than a preset temperature calibration value, the battery power is greater than a preset power calibration value, and the maximum allowable discharge power of the battery is greater than a preset power calibration value, the fourth vehicle ready flag is positioned.

[0080] It should be understood that when the battery temperature is greater than or equal to a calibration value T1 (i.e., a preset temperature calibration value, the value of which can be calibrated according to actual conditions), the battery power is greater than or equal to a calibration value S1 (i.e., a preset power calibration value, the value of which can be calibrated according to actual conditions), and the maximum allowable discharge power of the battery is greater than or equal to a calibration value P1 (i.e., a preset power calibration value, the value of which can be calibrated according to actual conditions), the fourth vehicle ready flag is positioned, otherwise it is reset.

[0090] Step S302, if the vehicle ready signal is in a ready state at the previous moment and the vehicle ready reset flag is set, the vehicle ready signal is adjusted to a non-ready state.

[0091] It is worth noting that the vehicle ready signal can be calculated according to the vehicle ready reset flag signal. If the vehicle ready signal is in a ready state at the previous moment, the following judgment is made: when the vehicle ready reset flag is set, the vehicle ready signal is output as a non-ready state, otherwise the vehicle ready signal is still in a ready state.

[0092] Step S303, if the vehicle ready signal is in a non-ready state at the previous moment and the vehicle ready flag is set, the vehicle ready signal is adjusted to a ready state.

[0093] It is worth mentioning that if the vehicle ready signal is in the "non-ready state" at the previous moment, the following judgment is made: when the vehicle ready flag is set, the vehicle ready signal output is in the "ready state", otherwise the vehicle ready signal is still in the "non-ready state".

[0094] In this embodiment, the vehicle ready reset flag is set when the vehicle ready first flag is reset, the vehicle ready second flag is reset, or the PEPS start button request is a lower ready request. If the vehicle ready signal is in the ready state at the previous moment and the vehicle ready reset flag is set, the vehicle ready signal is adjusted to the non-ready state. If the vehicle ready signal is in the non-ready state at the previous moment and the vehicle ready flag is set, the vehicle ready signal is adjusted to the ready state. By adjusting the vehicle ready signal through the vehicle ready reset flag and the vehicle ready flag, the vehicle ready state can be calculated more accurately.

[0095] In this embodiment, by obtaining the BMS high-voltage relay actual state, the PEPS start button request, the gear, the brake pedal state, the vehicle speed validity flag, the fast charging gun connection flag, the slow charging gun connection flag, the V2L discharge gun connection flag, the V2V discharge gun connection flag, the battery temperature, the battery power, the maximum allowed discharge power of the battery, the actual working mode of the motor, the motor three fault flag, the TCU gear hub self-learning request flag, the TCU gear hub self-learning state, the left front door state, the left front seat belt state signal and other electric vehicle running information, combined with the above running information and the high voltage request flag of the vehicle, the vehicle ready signal is calculated, so that the vehicle ready state can be calculated more accurately.
