PROBLEM TO BE SOLVED: To provide a speed controller for vehicle with which comfortable/safe travel can be provided by decreasing the driving operation load of a driver by traveling a vehicle basically without requiring any accelerator operation to the driver. SOLUTION: Speed control is executed by adjusting the driving power of an engine 24 so that real car speed can be coincident with target car speed but this speed control is executed by utilizing a navigation function. Namely, a CD-ROM 5a stores map data expressing a road map and reference speed determined based on critical speed on that road at least and based on the current position of a present vehicle, the reference speed is read out of the map data corresponding to the road where the present vehicle is traveled at present. Then, the target speed is determined based on that read reference speed and the speed control is executed. |
