The invention discloses a driving track generation method and device, and the method comprises the steps: enabling a driving scene or the driving style difference of a driver to affect a driving track, and determining a characteristic parameter which indicates the influence degree of a deviation between a driving target parameter and a driving average parameter, and determining the driving track in combination with the driving average parameter and the vehicle motion parameter, such as the deviation between the target lane-changing lateral displacement and the average lane-changing lateral displacement, and/or the deviation between the target lane-changing time and the average lane-changing time. The characteristic parameters for indicating the driving scene differences or the driving style differences are introduced, so that the problem that the fixed average driving parameters cannot accurately express the driving track differences of various driving scenes and various driving styles is solved, and the accuracy and intuition of driving track modeling are improved.
本申请公开了一种行驶轨迹生成方法以及装置,该方法包括:驾驶场景或驾驶员的驾驶风格差异会影响行驶轨迹,通过确定指示行驶目标参数与行驶平均参数之间的偏差的影响程度的特征参数,如指示目标变道横向位移和平均变道横向位移的偏差,和/或,目标变道时间和平均变道时间的偏差,结合行驶平均参数和车辆运动参数来确定行驶轨迹。由于引入了指示驾驶场景差异或驾驶风格差异的特征参数,解决了固定的行驶平均参数无法精确表达各类驾驶场景、各类驾驶风格行驶轨迹差异的问题,提升了行驶轨迹建模的准确性、直观性。
