  • Patent number: 9688161
    Abstract: A slip control device for an electric vehicle which accurately 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 calculation module (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 drive wheel (7) has slipped, and a torque limitation (25) limits a torque when a slippage has occurred. The determination (23) determines the angular acceleration and a threshold. The determination (23) counts a number of consecutive times it is determined that the threshold is exceeded, and determines that a slippage has occurred, if the number of consecutive times has reached a set value.

  • Patent number: 9550435
    Abstract: An angular acceleration monitor may monitor whether or not an angular acceleration of a wheel detected by an angular acceleration detector is equal to or smaller than an acceptable angular acceleration (W) that is calculated with the following formula: W=k1×R×Tt/m/r2 where k1 is a constant, Tt is a total drive torque that is a sum of drive torques of all motor units that drive wheels of the vehicle, m is vehicle mass, r is tire radius, and R is reduction ratio of a reducer unit interposed between the motor unit and the wheel. A slip-responsive controller causes, if it is determined that the acceptable angular acceleration is exceeded, a motor controller to reduce a drive torque of the motor unit(s).
