PURPOSE:To quickly adjust the inter-vehicle distance and make the succeeding travel after the adjustment coincide with driver's driving sense if the inter- vehicle distance is not adequate for the driver during following traveling in a travel controller for a vehicle in which speed reduction and acceleration control is conducted to follow the preceding car. CONSTITUTION:The detected signals from a car speed sensor 12 and an inter- vehicle distance sensor 10 are input to a micro computer 18. The micro computer 18 calculates the target inter-vehicle distance based on the car speed and drives a throttle actuator 20 to follow the preceding car. If the target inter-vehicle distance is not adequate, the driver manually operates an adjusting lever 14 to control throttle and changes the target inter-vehicle distance between the cars. At this time, based on car speed V0 at the time of starting the operation of the adjusting lever 14 and the inter-vehicle distance L0 at the time of finishing the operation of the adjusting lever 14, the new target inter-vehicle distance is set to perform succeeding following travel.
