The invention relates to a method for determining a speed profile to be followed by a vehicle, comprising the steps of: acquiring event data comprising a distance from an event and a target speed (V3) of said vehicle in the event; a speed profile to be followed in three consecutive different phases is determined as a function of time, between the initial speed (V0) and the target speed, which phases are respectively a first phase (Phase1) in which the jerk is set to be constant at a predetermined maximum jerk value in order to achieve an optimal target acceleration value, a second phase (Phase2) in which the jerk is set to be constant at a predetermined maximum jerk value in order to achieve an optimal target acceleration value, and a third phase (Phase3) in which the jerk is set to be constant at a predetermined maximum jerk value in order to achieve an optimal target acceleration value. Wherein said optimal target acceleration value remains constant, and a third phase (Phase3) wherein the jerk is set again to be constant in order to reach a zero acceleration value at the end of the third phase, said optimal target acceleration value being such that the distances required to execute the three phases of said curve are equal to said distance from the event.
本发明涉及一种用于确定车辆所要遵循的速度曲线的方法,该方法包括以下步骤:获取事件数据,该事件数据包括距事件的距离和所述车辆在该事件中的目标速度(V3);确定在三个连续的不同阶段中所要遵循的、作为时间的函数的速度曲线,该速度曲线在初始速度(V0)与该目标速度之间,这些阶段分别为第一阶段(Phase_1),其中将加加速度设置为恒定在预定最大加加速度值,以便达到最佳目标加速度值,第二阶段(Phase_2),其中所述最佳目标加速度值保持恒定,以及第三阶段(Phase_3),其中再次将该加加速度设置为恒定,以便在该第三阶段结束时达到零加速度值,所述最佳目标加速度值使得执行所述曲线的三个阶段所需的距离等于距该事件的所述距离。
