PURPOSE:To make overspeediness at time of constant speed running controllable in a simple structure by braking wheels with a braking system of the traction controller when these wheels have come to the overspeediness during constant speed running control, and controlling this overspeediness as specified. CONSTITUTION:In a device which controls any slip in braking driving wheels 1L, 1R by a brake controlling means 49 according to the detected result of slips of these driving wheels 1L, 1R, there is provided with a constant speed running control means 63 which receives each output signal of a car speed setting means 70 setting a desired car speed and a car speed detecting means 66 detecting the actual car speed, and controls output of an engine 5 so as to cause the car speed to become the desired one. Also there is provided with a control means 71 which receives each output signal of the car speed detecting means 66 and the constant speed running control means 63, and operates the brake controlling means 49 so as to lower the car speed when it goes up more than the desired car speed during constant speed running control by the constant speed running control means 63. |
