The invention discloses an automatic driving assistance method based on vehicle-road cooperation, and the method comprises the steps: arranging a roadside device on roadside equipment, and pre-storing the positioning information of the roadside equipment through a first storage module; a vehicle-mounted device is arranged on the automatic driving vehicle; in the driving process of the automatic driving vehicle, real-time positioning is carried out through a positioning module, and positioning information of the automatic driving vehicle is generated; under the condition that communication connection is established between the roadside device and the vehicle-mounted device, the first control module sends positioning information of the roadside device to the vehicle-mounted device; the second control module determines the distance between the automatic driving vehicle and the roadside equipment and the position of the roadside equipment according to the positioning information of the automatic driving vehicle and the roadside equipment; and the automatic driving system controls the driving route according to the distance between the automatic driving vehicle and the roadside equipment and the position of the roadside equipment. The method can provide assistance for the automatic driving vehicle to identify the road side boundary, thereby improving the automatic driving decision-making efficiency.

本发明公开了一种基于车路协同的自动驾驶辅助方法，包括：在路侧设备上设置路侧装置，通过第一存储模块预先存储路侧设备的定位信息；在自动驾驶车辆上设置车载装置；在自动驾驶车辆行驶过程中，通过定位模块进行实时定位，生成自动驾驶车辆的定位信息；在路侧装置与车载装置建立通信连接的情况下，第一控制模块将路侧设备的定位信息发送至车载装置；第二控制模块根据自动驾驶车辆以及路侧设备的定位信息，确定自动驾驶车辆与路侧设备之间的距离以及路侧设备的位置；自动驾驶系统根据自动驾驶车辆与路侧设备之间的距离以及路侧设备的位置，对行驶路线进行控制。本发明可以为自动驾驶车辆对于道路边线的识别提供辅助，进而提高自动驾驶决策效率。
