ABSTRACT:
A throttle valve position controlling apparatus comprises a motor serving to adjust the opening degree of a throttle valve disposed in an intake pipe of an engine, an air flow sensor attached to the intake pipe so as to detect an intake air amount, and a throttle control unit which is operative to obtain a deviation between a command air amount set beforehand and the intake air amount detectd by the air flow sensor and to effect a feed back control on the motor so as to minimize the deviation to zero. A slip controlling apparatus comprises revolution sensors for detecting the number of revolutions of driving wheels and driven wheels of a car, a slip control unit which has a table in which command air amounts are set beforehand in correspondence with the degree of slip and is operative to judge whether or not the car is in the state of slip from the results of detection by the revolution sensors and to retrieve the table, when the car is in the state of slip, so as to obtain a command air amount corresponding to the judged degree of slip.
