Abstract:
The embodiments of the present application disclose a stability control system and a stability control method for a four-wheel drive electric vehicle and the four-wheel drive electric vehicle. In the stability control system, when the lateral acceleration is equal to or greater than an acceleration threshold, at least one of a first braking force signal, a second braking force signal, a first logic signal and a second logic signal is obtained. When the first logic signal is obtained, the body of the electric vehicle is controlled to keep stable. When the first braking force signal and the second logic signal are obtained, a motor is controlled to apply braking force to an outside front wheel. When the second braking force signal and the second logic signal are obtained, motors are controlled to apply braking force to the outside front wheel and an inside rear wheel.

Claim (Index 2):
The stability control system for a four-wheel drive electric vehicle according to  claim 1 , wherein the first stability control unit is configured to:\n obtain the first logic signal to determine that the electric vehicle has a first trend when |LTR|<L1; obtain the first braking force signal and the second logic signal to determine that the electric vehicle has a second trend when L1\u2264|LTR|<L2; obtain the second braking force signal and the second logic signal to determine that the electric vehicle has a third trend when L2\u2264|LTR|\u2264L3; wherein LTR is the lateral load transfer ratio, |LTR| indicates the absolute value of the lateral load transfer ratio, L1 is the first transfer ratio threshold, L2 is the second transfer ratio threshold, L3 is the third transfer ratio threshold, the first transfer ratio threshold is greater than zero, the second transfer ratio threshold is greater than the first transfer ratio threshold, and the third transfer ratio threshold is greater than the second transfer ratio threshold and less than 1.
