The vehicle coasting energy recovery driving binding method according to claim 6 is characterized in that: The binding method further includes the following process: The vehicle sliding energy detection module satisfies the following conditions according to the vehicle sliding deceleration A: A<0.8m / s 2 When the power is off, it is classified as low-level energy recovery mode; The pedal module is classified into a medium pedaling feeling mode when the braking force F of the pedal pedaling stroke satisfies: 30N<F<35N; The vehicle driving module is classified into a sports driving mode when the vehicle's acceleration time T from 0 to 100 km / h satisfies: T<8s; When the car is in coasting driving, the low-level energy recovery mode, the medium pedaling feel mode and the sports driving mode are automatically bound and matched to form a third driving binding mode of the car, so that the pedal feel of the car remains consistent.

9. An electric vehicle having a coasting energy recovery system; characterized in that: The electric vehicle comprises the vehicle coasting energy recovery driving binding system as described in any one of claims 1 to 5 above.

10. The electric vehicle according to claim 9, characterized in that: The electric car is also provided with a vehicle controller, a DVD module and a knob, wherein the DVD module and the knob are electrically connected to the vehicle controller respectively; the DVD module is a touch screen structure and can be used to select various driving binding modes of the car; the knob can be turned to select various driving binding modes of the car.
