Abstract:
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; 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; and a headway distance threshold setting section configured to set the prescribed headway distance threshold based on a steady-state term that is computed irrespective of whether the preceding vehicle is decelerating and a transient term that is computed when the preceding vehicle is decelerating.
