PURPOSE:To prevent an engine from stopping when a motor-cycle body is jumped up, etc., by providing a sensor for the hull expansion of a driving-wheel suspension of a motor-cycle, etc., and stopping the operation of a carburetor control circuit based on the slip ratio of the driving wheel by means of the output of said sensor. CONSTITUTION:When driving a motor-cycle, signals proportional to the number of revolution of the corresponding wheels are outputted from speed sensors 2, 4 provided on each wheel shaft part 1a, 3a of front and rear wheels 1, 3, and the slip ratio of the rear wheel, i.e., a driving wheel 3, is calculated from both of these signals at a control unit (figure omitted) provided on the motor-cycle. In accordance with this slip ratio, the amount and direction of electricity to be applied to a motor 17 are controlled in a carburetor 19, thereby controlling the area of the opening of a main jet 16 through a needle 22. In this case, if a motor-cycle body jumps causing a rear suspension 15 to be fully expanded, and when a full-expansion sensor 10 is turned off, the slip prevention controlling action by means of said control unit is stopped, controlling the opening of the carburetor only by the operation of a throttle. |
