PROBLEM TO BE SOLVED: To provide a motion controller for a vehicle making a deceleration control for suppressing a feeling of strangeness to a driver when passing a curve existing in front of the vehicle. SOLUTION: When recognizing the existence of a curve while performing constant-speed control for keeping a vehicle speed Vx to a set vehicle speed Vo, the motion controller for a vehicle calculates a target vehicle speed characteristic Vt (A-B line) for decelerating the vehicle to the vehicle speed Vq at the point Pcr, based on "a decrement characteristic of the vehicle speed determined based on preliminary stored prime motor braking torque characteristics and preliminary set shift patterns of a transmission", an appropriate vehicle speed Vq for curve traveling, and a target point Pcr for attaining the vehicle speed Vq. Then, when a relationship between relative positions of the curve and the vehicle, and the vehicle speed Vx satisfies the target vehicle speed characteristic Vt (point Pcs 1), deceleration control is started/performed. Under deceleration control, the prime motor braking torque is applied to the vehicle, and the transmission is shifted down according to the shift patterns. COPYRIGHT: (C)2009,JPO&INPIT
