Compared with traditional fuel vehicles, electric vehicles are generally equipped with motors and batteries, and hybrid electric vehicles are even equipped with generators and engines. In order to ensure the safety of the entire electric vehicle, the entire vehicle must be ready before it can start driving.

First, the electric power operation information of the electric vehicle is obtained. The electric power operation information mainly refers to the working state and characteristics of the motor, battery and electronic control system. These components together constitute the "three-electric" system of new energy vehicles, which not only provides power for the vehicle, but also ensures the stable and efficient operation of the vehicle through fine control. Therefore, the high-voltage request flag on the vehicle can be determined according to the obtained electric power operation information to determine the ready state of the vehicle.

Please refer to Figure 3 , step S20, the vehicle ready calculation method further includes steps S201 to S207:
[0072] Step S201, when the high voltage request flag on the vehicle is in position and the actual state of the BMS high voltage relay is in the energized state, the first flag of the vehicle ready is in position.

The vehicle ready signal can be calculated by combining the above-mentioned operation information and the high-voltage request flag on the vehicle calculated by the previous module.
[0074] It should be understood that when the high voltage request flag on the vehicle is set and the BMS high voltage relay request state is "closed", the vehicle ready first flag is set, otherwise it is reset.
[0075] Step S202, when the actual working mode of the motor is the torque mode and the third-level fault flag of the motor is reset, the second flag of the vehicle ready is set.
[0076] It can be understood that when the actual working mode of the motor is "torque mode" (i.e. torque mode) and the motor's third-level fault flag is reset, the vehicle's ready second flag is set, otherwise it is reset.
[0077] Step S203, when the PEPS start button request is a ready request, the gear is in the parking gear, the brake pedal state is in the braking state, the vehicle speed validity flag is in position, 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, then the vehicle ready third flag is in position.
[0078] It can be understood that when the PEPS start button request is "ready request", and the gear position is "P gear" (i.e. parking gear), and the brake pedal state is "pressed" (i.e. braking state), and the vehicle speed validity flag is in position, and the fast charging gun connection flag is reset, and the slow charging gun connection flag is reset, and the V2L discharge gun connection flag is reset, and the V2V discharge gun connection flag is reset, then the vehicle ready third flag is in position, otherwise it is reset.
[0079] Step S204, when the battery temperature is greater than the preset temperature calibration value, the battery power is greater than the preset power calibration value and the battery maximum allowable discharge power is greater than the preset power calibration value, the fourth vehicle ready flag is set.
[0080] It should be understood that when the battery temperature ≧ calibration value T1 (i.e. the preset temperature calibration value, the value can be calibrated according to the actual situation), and the battery power ≧ calibration value S1 (i.e. the preset power calibration value, the value can be calibrated according to the actual situation), and the battery maximum allowable discharge power ≧ calibration value P1 (i.e. the preset power calibration value, the value can be calibrated according to the actual situation), the fourth flag of the vehicle ready is in position, otherwise it is reset.

[0082] It can be understood that when the TCU shift hub self-learning request flag is reset, or the TCU shift hub self-learning status is "no shift drum self-learning" or "shift drum self-learning successful", the vehicle ready fifth flag is set, otherwise it is reset.
[0083] Step S206, when the left front door is in the closed state or the left front seat belt is in the fastened state, the sixth vehicle ready flag is in position.
[0084] It can be understood that when the left front door status is "closed" or the left front seat belt status is "seat belt fastened", the sixth flag position of the vehicle ready is set, otherwise it is reset.

[0089] It should be noted that when the first flag of the vehicle ready is reset, or the second flag of the vehicle ready is reset, or the PEPS start button request is a "next ready request", the vehicle ready reset flag is set, otherwise it is reset.
[0090] Step S302: 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 a non-ready state.
[0091] It is worth noting that the vehicle ready signal can be calculated based on the vehicle ready reset flag signal. If the vehicle ready signal is in the "ready state" at the previous moment, the following judgment is made: when the vehicle ready reset flag is set, the vehicle ready signal output is "non-ready state", otherwise the vehicle ready signal is still in the "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 noting that if the vehicle ready signal is "not ready" at the previous moment, the following judgment is made: when the vehicle ready flag is set, the vehicle ready signal output is "ready", otherwise the vehicle ready signal is still "not ready".
[0094] In this embodiment, when the first flag of the vehicle ready is reset, the second flag of the vehicle ready is reset, or the PEPS start button request is a next ready request, the vehicle ready reset flag is set; 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 a 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 a ready state. The vehicle ready signal is adjusted by combining the vehicle ready reset flag with the vehicle ready flag, so that the vehicle ready state can be calculated more accurately.
