Abstract
A regional attribute for a region in which a vehicle is traveling is detected by a vehicle navigation device, and vehicle drive force characteristics such as a throttle gain of an electronic throttle or a speed change pattern of an automatic transmission are modified according to the regional attribute. An operation amount of an accelerator operated by a driver is detected, and by not modifying the drive force characteristics when the accelerator operation amount is not zero, abrupt change of drive force is avoided, and the sense of discomfort experienced by a driver due to abrupt change of drive force is eliminated.
