<P>PROBLEM TO BE SOLVED: To suppress uncomfortable feeling to a driver, and to improve drivability, in automatic constant-speed traveling such as cruise traveling. <P>SOLUTION: When target drive torque corresponding to a target drive force reaches a value smaller than on-road resistance torque by a reduction requirement of a target drive force by the driver in a state that processing is performed for calculating the target drive force for automatically adjusting a traveling state to a state which is set by the driver, a degree of increase in the target drive torque is changed, the degree being obtained until when the target drive torque increasing from an inversion timing at which the reduced target drive torque is inverted to increase reaches the on-road resistance torque, and when the inversion timing is in conjunction with the stop operation of the reduction requirement by the driver, processing is performed for making the degree of increase in the target drive torque larger than when the inversion timing is not in conjunction with the stop operation of the reduction requirement by the driver. <P>COPYRIGHT: (C)2012,JPO&INPIT |
