The invention provides a vehicle driving assistance method, which aims at providing guidance for vehicle driving speed, and comprises the following steps: acquiring a speed limit identifier of a current road and a speed limit value on the speed limit identifier; and in response to the acquisition of the speed limit identifier, executing auxiliary operation, including collecting auxiliary data and acquiring at least one reference vehicle speed value based on the auxiliary data, and when a difference value between the speed limit value and the at least one reference vehicle speed value exceeds a predetermined threshold value, determining a vehicle speed guidance value based on the speed limit value and the at least one reference vehicle speed value to guide the vehicle to run. According to the vehicle driving auxiliary method provided by the invention, when the upper limit of the vehicle driving speed needs to be determined when encountering the road speed limit sign, the influence of light shadow or shielding objects on the identification of the road speed limit sign can be reduced as much as possible, and safe and reliable guidance is provided for the vehicle driving; the risk that traffic rules are violated and even traffic accidents are caused due to identification errors is reduced, and the stability of the automatic driving system is improved. The invention further provides a corresponding vehicle driving auxiliary system and a vehicle.
本发明提出一种车辆行车辅助方法,旨在能够为车辆行驶速度提供指导,其包括:获取当前道路的限速标识和其上的限速值;响应于限速标识的获取执行辅助操作,包括收集辅助数据并基于辅助数据获得至少一个参考车速值和当限速值与至少一个参考车速值之间的差值超过预定阈值时,基于限速值和至少一个参考车速值确定车速指导值以指导车辆行驶。根据本发明的车辆行车辅助方法,能够在遇到道路限速标识而需要确定车辆行驶速度上限时,尽可能地降低光影或遮蔽物对道路限速标识的识别的影响,为车辆行驶提供安全可靠的指导,降低因识别错误而违反交通规则甚至造成交通事故的风险,提高自动驾驶系统的稳定性。本发明还提出了相应的车辆行车辅助系统和车辆。
