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 1):
A stability control system for a four-wheel drive electric vehicle, comprising a vehicle controller and a signal detection sensor, wherein the vehicle controller comprises a first stability control unit and a second stability control unit;\n the signal detection sensor is configured to detect lateral acceleration signals; the first stability control unit is configured to continuously determine whether the lateral acceleration is less than a preset acceleration threshold, until the lateral acceleration is equal to or greater than the acceleration threshold; the first stability control unit is further configured to calculate a lateral load transfer ratio according to the lateral acceleration signals when the lateral acceleration is equal to or greater than the acceleration threshold, and to determine the state of the vehicle according to the lateral load transfer ratio to obtain at least one of a first braking force signal, a second braking force signal, a first logic signal and a second logic signal; the second stability control unit is configured to control the body of the electric vehicle to keep stable when obtaining the first logic signal; the first stability control unit is further configured to control a motor of the electric vehicle via a motor controller of the electric vehicle to apply braking force to an outside front wheel of the electric vehicle when obtaining the first braking force signal and the second logic signal; and the first stability control unit is further configured to control motors of the electric vehicle via motor controllers of the electric vehicle to apply braking force to the outside front wheel of the electric vehicle and an inside rear wheel of the electric vehicle when obtaining the second braking force signal and the second logic signal.
