The invention relates to a method for operating a motor vehicle (1) which has multiple drive wheels (4-7) and multiple drive machines (8-11), wherein each drive wheel (4-7) is paired with a respectivedrive machine (8-11), in particular an electric machine. The method has the following steps: detecting a total target drive torque, - detecting a current vehicle speed, a current steering angle, andoptionally the wheel loads of all of the drive wheels (4-7), determining wheel-individual movement speeds of the drive wheels (4-7) over the roadway depending on the current vehicle speed, the currentsteering angle, a known body geometry of the motor vehicle (1), and optionally the wheel loads, determining a target rotational speed for each drive wheel (4-7) depending on the determined movement speeds and distributing the total target drive torque to all of the drive wheels (4- 7) such that an actual curved path deviates from a target curved path specified by the steering angle, and actuatingeach drive machine (8-11) in order to adjust a target rotational speed of each drive wheel (4-7).

    本发明涉及一种用于运行机动车(1)的方法,所述机动车具有多个驱动轮(4‑7)以及多个驱动机(8‑11),其中,给每个驱动轮(4‑7)分别配设一个驱动机(8‑11)、尤其是电机,所述方法具有以下步骤:‑检测总目标驱动转矩;‑检测当前的车辆行驶速度、当前的转向角以及可选地所有驱动轮(4‑7)的车轮负荷;‑根据机动车(1)的当前的车辆行驶速度、当前的转向角、已知的行驶机构几何结构和可选地车轮负荷来确定驱动轮(4‑7)在车道上的车轮单独的运动速度;‑根据所确定的运动速度确定用于每个驱动轮(4‑7)的目标转速,并且将所述总目标驱动转矩如此分配到所有的驱动轮(4‑7)上,使得实际弯道轨迹与由所述转向角预先给定的目标弯道轨迹有偏差;‑操控每个驱动机(8‑11)以用于调整在相应的驱动轮(4‑7)上的目标转速。
