The invention provides a bus intelligent driving assistance system and method based on vehicle-road cooperation, and belongs to the technical field of bus automatic driving, and the method comprises the steps that a vehicle-mounted terminal sends vehicle speed information and vehicle position information to a road side unit; the road side unit sends the obstacle information and the traffic light state information to the vehicle-mounted terminal; an intelligent driving control system calculates the driving state control information of the vehicle according to the vehicle speed information, the vehicle position information, the obstacle information and the traffic light state information, and the driving state of the vehicle is controlled by the driving control system of the vehicle according to the driving state control information of the vehicle. Information such as the number, the positions, the speeds and the course angles of obstacles can be provided, real-time communication within the range of 500 m can be achieved through the vehicle-mounted terminal and the road side unit, the states of pedestrians, vehicles and traffic lights at a traffic intersection can be obtained in advance, obstacle information and traffic light state information are judged through the intelligent driving control system, and the intelligent driving bus can be ensured to pass through the traffic intersection more safely and efficiently.
本发明提供基于车路协同的公交车智能驾驶辅助系统及方法,属于公交车自动驾驶技术领域,包括车载终端将本车速度信息、本车位置信息发送给路侧单元;路侧单元将障碍物信息以及交通灯状态信息发送给车载终端;智能驾驶控制系统根据车本车速度信息、本车位置信息、障碍物信息以及交通灯状态信息计算本车行驶状态控制信息,本车驾驶控制系统根据本车行驶状态控制信息控制本车的行驶状态。本发明可提供障碍物的数量、位置、速度和航向角等信息,车载终端与路侧单元可实现500m范围内的实时通讯,可提前获知交通路口行人、车辆和交通灯状态,通过智能驾驶控制系统对障碍物信息以及交通灯状态信息进行判断,保障智能驾驶公交车可以更加安全、高效的通行交通路口。
