Abstract
A control device for a vehicle which has a function to reduce the change-speed shock when changing the speed by controlling the transmission of the vehicle. The control device performs the switching between a manual change-speed mode in which the vehicle speed can be changed based on a change-speed command generated by manual operation and an automatic change-speed mode in which a transmission gear ratio can be controlled based on the predetermined change-speed characteristic. Thereby the reduction amount of the change-speed shock can be changed between the manual change-speed mode and the automatic change-speed mode.
