Running control system
A running control system of the present invention includes 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 a signal from the braking operation detection device. If an operation by the driver for requesting the follow-running control is detected by the driver 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.
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.
2. The running control system according to claim 1 , wherein
the braking operation detection device outputs an output signal in response to the braking operation by the driver, and
the running control device terminates the follow-running control with respect to the preceding vehicle in response to a changing point in the output signal from the braking operation detecting device, which indicates a beginning of the braking operation by the driver.
3. 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 the follow-running control by the driver;
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; and
a throttle opening control device for controlling a degree of opening of a throttle of the present vehicle based on control by the running control device; wherein
if the operation for requesting the follow-running control is input by the driver while the braking operation by the driver is detected by the braking operation detection device, the running control device starts the follow-running control, and the throttle opening control device maintains the degree of opening of the throttle in a fully-closed state while detecting the driver's braking operation.
4. The running control system according to claim 3 , wherein
the braking operation detection device outputs the output signal in response to the braking operation by the driver, and
the running control device terminates the follow-running control with respect to the preceding vehicle in response to a changing point in the output signal from the braking operation detecting device, which indicates a beginning of the braking operation by the driver.
