AI Technical Summary

Technical Problem

In existing technology, when a vehicle passes through a traffic light, the driver repeatedly accelerates and decelerates, causing discomfort to the occupants.

Method used

By installing a traffic light recognition device and a position detection device in front of the vehicle, the color of the traffic light is identified and the vehicle speed is controlled, so that the vehicle travels at a constant speed below the target speed when the distance between traffic lights is short, until the color of the traffic light is identified as green.

Benefits of technology

This reduces the repeated acceleration and deceleration of vehicles between traffic lights, thus reducing passenger discomfort.

Abstract

驾驶辅助装置(1)具备信号识别装置和速度控制装置。速度控制装置以使本车辆到达可识别地点(Pr1)的时刻的车速(Vs)为比目标值(Vd)低的目标值(V1)以下的方式，从可识别地点的近前开始控制本车辆的驱动装置(20)及制动装置(30)，该可识别地点与位于本车辆前方的最接近的信号灯(S1)之间的距离为规定值(Lr)，并且，速度控制装置在信号识别装置识别信号灯(S1)的灯光颜色而该灯光颜色为绿色、且信号灯(S1)与在该信号灯(S1)的前方相邻的信号灯(S2)之间的距离(DS)为规定的阈值(DSth)以下的情况下，以使本车辆以目标值(V1)以下的速度定速行驶的方式控制驱动装置及制动装置，直到信号识别装置识别信号灯(S2)的灯光颜色为止。
