Example Embodiment
[0050] Example one:
[0051] figure 1 This is a schematic flow chart of a method for recovering energy from a car coasting provided by an embodiment of this application.
[0052] Such as figure 1 As shown, the method includes the following steps:
[0053] S100: Obtain the current vehicle speed, calculate the drag torque at the engine end according to the current vehicle speed and the calibrated coasting deceleration, and calculate the initial feedback torque of the motor based on the drag torque.
[0054] When recovering the taxiing energy of a car, it is first necessary to obtain the current speed of the car, and decide how to recover the taxiing energy according to the current speed. The calibrated coasting deceleration refers to the corresponding relationship between the allowable coasting deceleration and the vehicle speed. In practical applications, it can be obtained through experimental calibration.
[0055] In the embodiment of this application, when calculating the drag torque...
