The invention relates to the technical field of automobile automatic driving, in particular to a front curve detection system and method for automotive self-adaptive cruise. In the vehicle self-adaptive cruise state, vehicle rough positioning information sent by a GPS is received in real time; automatic driving map information around the vehicle is obtained according to the vehicle rough positioning information, and road information around the vehicle is obtained by using a camera; if the camera can acquire the information of the road around the vehicle, the automatic driving map information is compared with the information of the road around the vehicle to realize accurate positioning of a lane level, and then information of a curve in front of the vehicle is obtained; and if the camera cannot acquire the information of the road around the vehicle, front curve information acquired by the front vehicle is received, and front curve information of the vehicle is acquired according to thefront curve information acquired by the front vehicle. An automatic driving map, a vehicle-mounted camera and a V2X vehicle communication technology are used for achieving front curve recognition, two sets of systems which are redundant to each other are formed, and the robustness of the systems is effectively improved.
本发明涉及汽车自动驾驶技术领域,具体涉及一种汽车自适应巡航的前方弯道检测系统及方法。车辆自适应巡航状态下,实时接收GPS发送的车辆粗略定位信息;根据车辆粗略定位信息获取车辆周围的自动驾驶地图信息,同时利用摄像头获取车辆周围道路信息;若摄像头能获取车辆周围道路信息,则将自动驾驶地图信息与车辆周围道路信息进行对比,实现车道级的精确定位,然后获取车辆的前方弯道信息;若摄像头无法获取车辆周围道路信息,则接收前车获取的前方弯道信息,并根据前车获取的前方弯道信息获取自车前方弯道信息。使用自动驾驶地图、车载摄像头及V2X车辆通信技术来实现前方弯道识别,形成两套互为冗余的系统,有效提高系统的鲁棒性。
