电动车辆控制装置
Abstract:
作为驱动车辆的车轮(2)的全部电动机(6)的驱动转矩的总和的总驱动转矩为(Tt)、车辆质量为(m)、轮胎半径为(r)、插入电动机(6)和车轮(2)之间的减速器(7)的减速比为(R)。设置角加速度监视机构(37)，其监视车轮(2)的通过角加速度检测机构(39)而检测的角加速度是否在通过式W＝k1×R×Tt/m/r2(k1为常数)而计算的允许角加速度(W)以下。设置滑移对应控制机构(38)，该机构在判定为超过允许角加速度(W)时，在电动机控制部分(33)中减少电动机的驱动转矩。
Abstract(English):

Tt represents the total drive torque which is the sum of the drive torques of all motors (6) driving the wheel (2) of a vehicle, m represents the mass of the vehicle, r represents the radius of a tire, and R represents the speed reduction ratio of a decelerator (7) inserted between the motors (6) and the wheel (2). An angular acceleration monitoring means (37) monitors whether the angular acceleration of the wheel (2) detected by means of an angular acceleration detection means (39) is equal to or less than a permissible angular acceleration (W) calculated by means of equation W-K1RTt/m/r2 (K1 being a constant). A slip-adaptive control means (38) allows a motor control part (33) to reduce the drive torque of a motor when it is determined that the angular acceleration surpasses the permissible angular acceleration (W).
