PROBLEM TO BE SOLVED: To provide a speed controller for suppressing unreasonable mutual passing behavior of vehicles the speed differences of which are small.SOLUTION: The speed controller 1 includes a relative-speed measurement unit 13 for measuring a speed difference between a self-vehicle 100 and a preceding vehicle traveling, immediately prior to own vehicle 100; and a control ECU 10 for adjusting the speed of own vehicle 100. When the speed difference measured by the relative speed measurement unit 13 is smaller than a prescribed value, the speed control ECU 10 adjusts the speed of own vehicle 100 so that the speed matches the speed of the preceding vehicle; moreover, when the speed difference is equal to or more than the prescribed value and when it is predicted that a vehicle traveling behind own vehicle 100 catches up with own vehicle until the time the vehicle 100 completes passing of the preceding vehicle, the control ECU adjusts the speed of own vehicle 100 so that the speed matches the speed of the preceding vehicle. |
