    • Wheel speed sensors arranged at each of driving wheels and idler wheels detect rotational speeds of corresponding wheels. ECU includes a wheel speed calculating portion calculating wheel speeds of the driving wheels and the idler wheels based on the detected rotational speeds, and an abnormality detecting portion detecting abnormality of the wheel speed sensors based on the calculated wheel speeds. The abnormality detecting portion detects the abnormality of the wheel speed sensors based on: a first wheel speed that is at least one of the wheel speeds of the driving wheels and the idler wheels being substantially zero; at least one of the wheel speeds except for the first wheel speed being greater than a prescribed threshold value; and an average wheel speed of the idler wheels being greater than an average wheel speed of the driving wheels.
    • 布置在每个驱动轮和惰轮上的车轮速度传感器检测相应车轮的转速。 ECU包括基于检测到的转速来计算驱动轮和惰轮的轮速的车轮速度计算部,以及基于所计算的车轮速度来检测车轮速度传感器的异常的异常检测部。 所述异常检测部根据作为所述驱动轮和所述惰轮的车轮速度中的至少一方的第一车轮速度基本上为零来检测所述车轮速度传感器的异常; 除了第一车轮速度之外的车轮速度中的至少一个大于规定的阈值; 并且惰轮的平均车轮速度大于驱动轮的平均车轮速度。

    • There is provided wheel speed detection means for detecting a wheel speed V based on a pulse signal corresponding to a rotational speed of a wheel, driving torque integration means calculates an integral value TINdt of driving torque TIN generated by the engine, and running situation determination means determines a vehicle running situation based on an actual wheel speed V and the integral value TINdt of the driving torque TIN. That is, the running situation determination means appropriately determines the vehicle running situation by comparing the actual wheel speed V which varies according to the vehicle running situation, and the function f (TINdt) even when the actual wheel speed is in the extremely low speed region. The function f (TINdt) is the function of the integral value TINdt of the driving torque TIN, and is also the function of the estimated wheel speed VP that is estimated based on the integral value TINdt of the driving torque TIN.
    • 提供了用于根据对应于车轮转速的脉冲信号来检测车轮速度V的车轮速度检测装置,驱动转矩积分装置计算驱动转矩T < SUB> IN ,运行状况判定单元根据实际车轮速度V和驱动转矩T IN 。 也就是说,运行状况判定单元通过比较根据车辆行驶状态而变化的实际车轮速度V和函数f(T> IN
      )来适当地确定车辆行驶状况,即使实际 车轮速度处于极低速度区域。 函数f(T IN T IN)是驱动转矩T IN IN IN的积分值T IN IN IN的函数,并且也是 基于驱动转矩T IN IN IN的积分值T IN IN估计的估计车轮速度V P P N的函数。
