The invention provides a self-adaptive auxiliary driving system based on a pavement environment. The system comprises: a signal acquisition unit which comprises a TBOX, a temperature sensor and an image acquisition device, wherein the TBOX is used for acquiring a current place and real-time weather of a vehicle, the temperature sensor is used for acquiring real-time temperature, and the image acquisition device is used for acquiring an image of the environment of a vehicle body; a signal processing unit which integrates signals of the TBOX and the temperature sensor, and compares the signals with information acquired by the image acquisition device to obtain the current road condition; a safety evaluation unit which acquires vehicle body parameters from a vehicle CAN bus and evaluates vehicle braking and steering safety according to the current road condition; and a self-adaptive execution unit which automatically adjusts the safe vehicle following distance, the braking time and the steering angle acceleration value in the current state according to the feedback result of the safety evaluation unit, so that the vehicle adapts to the current weather and road surface conditions. According to the system, the current road surface information is accurately obtained, the performance of the ASAD system is adaptively adjusted, and the driving safety is improved.
本发明提供一种基于路面环境的自适应辅助驾驶系统,其信号采集单元包括TBOX、温度传感器和图像采集装置,TBOX获取车辆当前地点与实时天气,温度传感器获取实时温度,图像采集装置采集车身所述环境的图像;信号处理单元整合TBOX、温度传感器信号,并与图像采集装置采集的信息比对,得到当前路面情况;安全评估单元从车辆CAN总线获取车身参数,根据当前路面情况评估车辆刹车及转向安全性;自适应执行单元根据安全评估单元的反馈结果自动调整在当前状态下的安全跟车距离、刹车时机以及转向角加速度值,以使车辆适应当前天气和路面情况。本发明准确获取当前路面信息并自适应调整ASAD系统性能,提高了驾驶安全性。
