PURPOSE:To prevent a tight corner braking phenomenon from occurring, by installing a detecting part which detects an inertial slow speed run from each output of a car speed switch, a neutral switch and a clutch switch and, at the time of detecting this inertial slow speed run, making a car perform a two-wheel drive run. CONSTITUTION:There are provided with a reverse switch 50 detecting a forward-backward motion by means of whether or not shifting to a reverse step, a 4WD switch 51 detecting operation on two-wheel drive or four-wheel drive, a neutral switch 52 detecting a neutral position, a clutch switch 53 detecting the extent of clutch pedal operation and a car speed switch 54 detecting a slow speed run, for example, of less than 5km/h. And, at an inertial slow speed run detecting part 55 inside a control circuit 46, the inertial slow speed run is detected from each output of these switches 52-54, and also a running mode is judged by a running model judging part 56 from each output of this detecting part 55 and each of these switches 50, 51 and 54, and at the time of detecting the inertial slow speed run, it is controlled so as to perform a two-wheel drive run.
