摘要:
A slip control device for an electric vehicle which errorlessly determines slippage occurrence with only a rotation angle sensor for motor rotation control and perform rapid control to eliminate the slippage, is provided. A threshold calculator 21 calculates a normal angular acceleration of a motor depending on a manipulation amount of an accelerator to obtain a threshold, and an angular acceleration calculator 22 differentiates a detection value from a rotation angle sensor 3a twice to calculate an angular acceleration. A slip determination 23 determines whether a wheel 7 driven by a motor 3 has slipped, and a torque limitation 25 limits a torque when determining a slippage. The determination 23 compares the calculated acceleration to the threshold, counts a number of times it is consecutively determined that the calculated acceleration exceeds the threshold, and determines a slippage if the number of times has reached a set value.

一种用于电动车辆的滑动控制装置,其仅利用用于电动机旋转控制的旋转角度传感器无误地确定滑动发生,并且执行快速控制以消除滑动。 阈值计算器21根据加速器的操作量来计算马达的正常角加速度以获得阈值,并且角加速度计算器22将来自旋转角度传感器3a的检测值区分两次以计算角加速度。 滑动判定23判断由电动机3驱动的车轮7是否滑动,并且转矩限制25在确定滑动时限制转矩。 判定23将计算出的加速度与阈值进行比较,计算连续确定计算出的加速度超过阈值的次数,并且如果次数达到设定值,则判定滑移。
