PURPOSE:To smoothly start a vehicle by speeding up an engine from its idle running when the vehicle is released from a non-creep condition, in the case of an automatic speed change system equipping a non-creep mechanism. CONSTITUTION:A central processing unit (CPU) 34, deciding a non-creep condition to be formed, outputs a control instruction for oil to a clutch by reading through an input interface 33 a sensor output signal from a shift position sensor S1 detecting whether or not a shift lever is placed in a position D, water temperature sensor S2 detecting the cooling water temperature of an engine to reach a certain value, car speed sensor S3, throttle sensor S4, engine speed sensor S5 and a brake sensor S6. Then the CPU34, if it decides the non-creep condition not to be formed, causes a vehicle to smoothly start by driving a driver 40 so as to speed up the engine from its idle running. |
