PURPOSE:To prevent the dragging of brake due to air leak in a case in which differential brake control valves causes air leak under the normal travel condition of car wheels not slipping, by discharging leaked air through discharge openings having throttles. CONSTITUTION:A computer 32 decides whether or not right and left drive wheels 12 have slipped by conducting the comparison of the detection o...

PURPOSE:To improve the running quality and the fuel consumption by controlling a speed change mode to be switched to an economy mode when an accelerator pedal is released further when predetermined deceleration is performed, in the time of a power mode selected. CONSTITUTION:In order to obtain predetermined speed change ratio being based on the detection result of each rotary speed of a primary pu...
