The invention relates to a method for determining and adjusting a minimum distance of travel when a vehicle is stopped, the vehicle having at least one electric machine, a vehicle network and a trajectory planner, in the method, at least the following method steps are operated: first, a change in a rotor angle or a rotor position angle or a rotor angular speed of the electric machine during a movement of the vehicle is sensed and transmitted to the microcontroller via the vehicle network. A travel distance traveled by the vehicle is determined from the sensed change in the rotor angle or rotor position angle or rotor angular velocity, taking into account the wheel radius, the kinematic transmission ratio and the differential ratio. And comparing the due driving distance of the vehicle with the driving distance that the vehicle has passed by. Finally, a desired value of the desired vehicle speed is determined by the trajectory planner on the basis of the remaining travel distance and is reduced to zero when approaching the target point. The invention further relates to the use of the method in hybrid and electric vehicles for determining and adjusting very small distances of travel.

    本发明涉及一种用于求取和调节在车辆停车时的最小行驶距离的方法,该车辆具有至少一个电机、车辆网络和轨迹规划器,在方法中至少运行以下方法步骤:首先感测电机的转子角或者转子位置角或者转子角速度在车辆运动期间的改变并且通过车辆网络传送给微控制器。考虑车轮半径、运动学变速器传动比和差速器传动比,根据转子角或者转子位置角或者转子角速度的所感测改变确定车辆走过的行驶距离。将车辆应有行驶距离与车辆已走过的行驶距离进行比较。最后,由轨迹规划器基于剩余行驶距离确定应有车辆速度的应有值并且在接近目标点时使该应有值降低到零。此外,本发明涉及所述方法在混合动力车辆和电动车辆中的应用,用于求取和调整非常小的行驶距离。
