Preceding vehicle following control system
First Claim
1. A preceding vehicle following control apparatus for controlling a controlled vehicle, the vehicle following control apparatus comprising:
- a vehicle speed sensor to sense an actual vehicle speed of the controlled vehicle;
a vehicle spacing sensor to sense actual vehicle spacing from the controlled vehicle to a preceding vehicle;
a vehicle speed controller to vary the actual vehicle speed of the controlled vehicle in accordance with a desired vehicle speed;
an anti-lock brake controller to perform an anti-lock brake control for preventing wheel locking; and
a vehicle speed controller to determine the desired vehicle speed in accordance with the actual vehicle speed and the actual vehicle spacing, the controller comprising, a following control section to perform a preceding vehicle following control by setting a desired vehicle spacing from the controlled vehicle to a preceding vehicle in accordance with the actual vehicle speed and actual vehicle spacing and determining the desired vehicle speed to bring actual vehicle spacing closer to desired spacing, a deceleration control section to perform a deceleration control determining the desired vehicle speed to decrease the actual vehicle speed of the controlled vehicle, and a mode change control section to cancel the following control of the following control section and instead compulsorily initiating the deceleration control of the deceleration control section in response to a start of the anti-lock brake control of the anti-lock brake controller.

Abstract
A preceding vehicle following control apparatus includes a sensor sensing an actual vehicle speed, a sensor sensing an actual vehicle spacing from a controlled vehicle to a preceding vehicle ahead, and an actuator for regulating a driving/braking force of the controlled vehicle. A controller controls the vehicle speed or the vehicle spacing in a following control mode with the actuator, and starts a deceleration control if an anti-lock brake control is started in the following control mode. The controller cancels the deceleration control when the vehicle spacing becomes greater than a predetermined spacing value.

13. A preceding vehicle following control apparatus for controlling a controlled vehicle, the vehicle following control apparatus comprising:
-
means for detecting an anti-lock brake control operation for preventing wheel locking of the controlled vehicle;
means for performing a vehicle following control for reducing a deviation of a sensed actual vehicle spacing from the controlled vehicle to a preceding vehicle, from a desired vehicle spacing;
means for performing a deceleration control for automatically decelerating the controlled vehicle; and
means for compulsorily starting the deceleration control when the anti-lock brake control is detected in the following control.

14. A preceding vehicle following control process for controlling a controlled vehicle, the vehicle following control process comprising:
-
detecting an anti-lock brake control operation for preventing wheel locking of the controlled vehicle;
performing a vehicle following control for reducing a deviation of a sensed actual vehicle spacing from the controlled vehicle to a preceding vehicle, from a desired vehicle spacing when the anti-lock brake control operation is not detected; and
compulsorily switching to a deceleration control for automatically decelerating the controlled vehicle when the anti-lock brake control operation is detected. - View Dependent Claims (15)
