Abstract:
1. A running control system comprising: a vehicle speed measuring device for measuring a running speed of a present vehicle; an object detecting device, provided in the present vehicle, for detecting objects in an advance direction of the present vehicle; a preceding vehicle determining device for determining a preceding vehicle to be followed by the present vehicle from among the detected objects; a target inter-vehicle distance determining device for determining a target inter-vehicle distance between the present vehicle and the preceding vehicle; a target speed determining device for determining a target speed of the present vehicle based on a signal from the object detecting device and the target inter-vehicle distance; a follow-running control device for controlling follow-running of the present vehicle with respect to the preceding vehicle based on the determined target speed and the running speed of the present vehicle; a braking operation detection device for detecting a braking operation performed by a driver of the present vehicle; a follow-up intention detection device for detecting an operation of requesting a follow-running control by the driver; and a running control device for aborting the follow-running control with respect to the preceding vehicle based on an output signal from the braking operation detection device, wherein if an operation by the driver for requesting the follow-running control is detected while the braking operation by the driver is detected by the braking operation detection device, the running control device starts the follow-running control after the end of the driver's braking operation.
