The invention discloses a vehicle driving curve determination method and device, and relates to the technical field of driving safety. The method comprises the steps that the steering angle, the width and the wheel track of a vehicle are obtained; determining a first radius and a circle center of a driving curve of the vehicle according to the steering angle, the width and the wheel track of the vehicle; determining second curve shape point groups on the two sides of the vehicle based on the first radius and the circle center of the first driving curve and the width of the vehicle; and generating two-side driving curves of the vehicle based on the second curve shape point groups on the two sides of the vehicle. Through the generated driving curves of the two sides of the vehicle, a driver is assisted to judge whether the vehicle is scratched or not during turning, the situation that the driver subjectively judges whether the vehicle is scratched or not only depending on driving experience is avoided, the judgment accuracy of the scratched situation is improved, and the driving experience of the driver is improved. Therefore, the situation that the vehicle is scratched when turning can be effectively avoided, and the driving safety of the vehicle is improved.
本申请公开了一种车辆行驶曲线的确定方法及装置,涉及驾驶安全技术领域。该方法包括:获取车辆的转向角、宽度以及轮距;根据车辆的转向角、宽度以及轮距,确定车辆的行驶曲线的第一半径和圆心;基于第一行驶曲线的第一半径、圆心以及车辆的宽度,确定车辆两侧的第二曲线形状点组;基于车辆两侧的第二曲线形状点组,生成车辆的两侧行驶曲线。本申请通过生成的车辆的两侧行驶曲线,辅助驾驶员判断车辆在转弯行驶时是否会出现刮蹭情况,避免驾驶员仅依赖于驾驶经验主观判断是否会出现刮蹭情况,提高了对刮蹭情况出现判断的准确性,从而能够有效避免车辆在转弯行驶时出现的刮蹭情况,提高车辆行驶的安全性。
