<P>PROBLEM TO BE SOLVED: To avoid the interference between the control concerned with the opening of an accelerator and the acceleration of a vehicle and the control of suppressing a slip, and improve the sensation of drive of a driver. <P>SOLUTION: This controller computes the rotational angle acceleration α of a drive shaft, from the number Nm of revolutions of a motor attached to the drive shaft (S100 and S102), and decides whether a vehicle is in a slippage state by the idling of a driving wheel, based on the rotational angle acceleration α(S104). When it is not in the slippage state, this executes acceleration management processing of setting a motor request torque Tm* so that the vehicle acceleration becomes the objective acceleration being set by an opening Acc of an accel and car velocity V (S108); and when it is in slip state, this executes the slippage control processing of limiting the motor request torque Tm*, which is set based on the opening Acc of the accel so as to suppress the slip, based on the rotational angle acceleration α, in place of the acceleration management processing(S110). <P>COPYRIGHT: (C)2004,JPO |
