The invention provides a control logic strategy of a novel electric vehicle controller for preventing sideslip and drifting of a vehicle. In order to achieve the purpose, according to the technical scheme, the torque rising slope of the controller at different vehicle speed sections is adjusted to be subjected to segmented processing, specifically, 1, the torque rising slope of the vehicle speed below 10 km/h is adjusted to be a large value which can be 1.5 times of the peak torque of a motor, and reference to the first'acceleration torque curve below 10 km/h '; 2, when the vehicle speed ranges from 10 km/h to 60 km/h, the torque rising slope is subjected to segmented weakening processing, and reference is given to an acceleration torque curve ranging from 10 km/h to 60 km/h in the figure 1; and 3, weakening the rising slope of the torque at the vehicle speed of more than 60km/h.

    本发明是提出一种新型电动汽车控制器防止车辆侧滑甩尾的控制逻辑策略。为了实现上述目的,本发明的技术方案是:调整控制器在不同车速段下的扭矩上升斜率做分段处理:1.将车速在10km/h以下的扭矩上升斜率调整为一个较大值,可以为电机峰值扭矩的1.5倍,参考图1“10km/h以下加速扭矩曲线”;2.将车速10km/h~60km/h之间时,将扭矩上升斜率再做分段弱化处理,参考图1“10km/h~60km/h之间加速扭矩曲线”;3.将车速60km/h以上的扭矩上升斜率同样做弱化处理。
