PURPOSE:To dissolve the physically discomfortable feeling of a driver by correcting the car speed function by the previously obtained correction value, on the basis of the drive state on the start of the coasting traveling. CONSTITUTION:In the coasting traveling, if a target deceleration speed learning circuit 450 calculates the correction value G2 of the target deceleration speed on the basis of the information supplied from a brake sensor 307, and a target deceleration speed setting circuit 452 sets the target deceleration speed G1 on the basis of the car speed signal VSP supplied from a car speed sensor 302, and corrects the target deceleration speed G1 by the correction value G2, and the target deceleration speed G* is outputted. While, a deceleration speed detecting circuit 454 detects the actual deceleration speed G, and a subtraction calculator 456 calculates the difference (e) between the target deceleration speed G*. Then, a feedback control circuit 458 carries out the PI control on the basis of the difference (e) and outputs the target speed change correction value DsrREV2. While, the target speed change value setting circuit 460 sets the target speed change value DsrREV1 on the basis of the car speed signal VSP and the throttle opening degree signal TV0, and the correction value DsrREV2 is added by an adder 462, and speed change control in coasting is carried out. |
