Abstract
A vehicle has a drive control ECU that controls an internal combustion engine or a transmission on the basis of a target drive force. The drive control ECU has a first arbitrator that sets the target drive force on the basis of a driver's request and the like, and filters that have individually different damping characteristics and that correct the target drive force from the first arbitrator so that the vibration of a sprung weight of the vehicle is controlled, as well as a switch that includes a switching portion and a filter setting portion. The filter setting portion determines whether a pitching resonance frequency has changed. If having determined that the pitching resonance frequency has changed, the filter setting portion switches the filter having been used for correcting the target drive force to a filter corresponding to a post-change pitching resonance frequency.
