The invention discloses a vehicle body stability control method based on a distributed driving electric vehicle, which comprises the following steps of: 1, establishing a phase plane stability formula, and judging an intervention proportion of a vehicle transverse stability controller; step 2, establishing a single-wheel and double-wheel switching controller, and formulating a single-wheel control rule of single-wheel driving or braking and a double-wheel control rule of diagonal wheel driving or braking; and 3, based on the principle of outputting a small control quantity, when the control quantity is within a set range, adopting single-wheel driving or braking, and when the control quantity exceeds the set range, adopting a double-wheel control rule. Driving/braking control of a single wheel or double wheels is achieved through cooperative control, on the premise that the transverse stability of the vehicle is guaranteed, the influence on the driving behavior of a driver is greatly reduced, and the longitudinal speed loss of the vehicle is reduced.

    本发明公开了一种基于分布式驱动电动汽车的车身稳定性控制方法,包括:步骤一、建立相平面稳定性公式,判断汽车横向稳定性控制器介入比例;步骤二、建立单双轮切换控制器,制定单轮驱动或制动的单轮控制规则和对角线车轮驱动或制动的双轮控制规则;步骤三、基于输出少控制量的原则,当在设定范围内时,采取单轮驱动或制动,超出设定范围时,采取双轮控制规则。通过协同控制实现单轮或双轮的驱/制动控制,在保证车辆横向稳定性的前提下,极大地降低了对驾驶员驾驶行为的影响,减少了车辆纵向速度损失。
