The invention belongs to the field of vehicle active safety, and discloses a driving track lamplight prediction system, a method and a vehicle. The system comprises an interaction control system and alight projection system; the interaction control system is used for judging whether the vehicle speed v is lower than a vehicle speed threshold value v0 or not, if yes, judging whether a road sectionwith the width w smaller than a road width threshold value w0 exists on the road surface where the vehicle is going to pass within the preset distance in front of the vehicle or not, If yes, generating a driving track prediction image equal to the vehicle in width for reminding a vehicle driver; and the lamplight projection system is used for projecting the image to the road surface to be passedso as to compare the width of the image with the width of the road surface to be passed and predict the trafficability of the vehicle on the road surface to be passed according to a comparison result.According to the method, the driving track of the vehicle is presented in advance by projecting the driving track prediction image with the same width as the vehicle on the road surface to be passed,and the trafficability of the vehicle on the road section is pre-judged by replacing the real vehicle with the driving track prediction image, so that the judgment efficiency and accuracy are improved.

    本发明属于汽车主动安全领域,公开了一种行驶轨迹灯光预测系统、方法及车辆,所述系统包括交互控制系统和灯光投射系统;交互控制系统用于判断车辆速度v是否低于车速阈值v0,若是,再判断车辆前方预设距离内欲行经路面上是否存在宽度w小于路宽阈值w0的路段,如是,则生成用于提醒车辆司机的与车辆等宽的行驶轨迹预测图像;灯光投射系统用于将该图像投射于欲行经路面,以便将该图像的宽度与欲行经路面的宽度进行对比,根据对比结果预测车辆在欲行经路面的可通过性。本发明通过在欲行经路面上投射与车等宽的行驶轨迹预测图像来预先呈现车辆的行驶轨迹,以行驶轨迹预测图像代替实车来预判车辆在该路段的可通过性,提高判断效率和准确性。
