VEHICLE HEADWAY MAINTENANCE ASSIST SYSTEM AND METHOD
First Claim
Patent Images
1. A vehicle headway maintenance assist system comprising:
- a headway distance detection section configured to detect a headway distance between a host vehicle and a preceding vehicle;
an accelerator actuation detection section configured to detect actuation of an accelerator of the host vehicle;
a deceleration control section configured to perform deceleration control of the host vehicle based on the headway distance when the accelerator is detected not as being operated while the headway distance detected by the headway distance detection section is less than a prescribed headway distance threshold; and
a reaction force control section configured to control a reaction force imparted to the accelerator when the accelerator actuation detection section detects actuation of the accelerator while the headway distance detected by the headway distance detection section is less than the prescribed headway distance threshold.

Abstract
A vehicle headway maintenance assist system is configured to perform a haptic notification control of an accelerator to prompt the driver to release the accelerator when the accelerator is being operated and to perform a deceleration control of the vehicle based on headway distance when the accelerator is being operated as long as the headway distance from a preceding vehicle is less than a prescribed headway distance threshold.

16. A vehicle headway maintenance assist system comprising:
-
headway distance detection means for detecting a headway distance between a host vehicle and a preceding vehicle; accelerator actuation detection means for detecting actuation of an accelerator of the host vehicle; deceleration control means for performing deceleration control of the host vehicle based on the headway distance when the accelerator is detected as not being operated while the headway distance detected by the headway distance means remains less than a prescribed headway distance threshold; and reaction force control means for controlling a reaction force imparted to the accelerator when the accelerator is being actuated while the headway distance detected by the headway distance means remains less than the prescribed headway distance threshold.

18. A vehicle headway maintenance assistance method comprising:
-
detecting a headway distance between a host vehicle and a preceding vehicle; and controlling deceleration of a host vehicle based on the headway distance that was detected when an accelerator is not being operated; and controlling a reaction force imparted to the accelerator when the accelerator is being actuated while the headway distance is less than a prescribed headway distance threshold.
