A method for operating a motor vehicle having multiple drive wheels and multiple drive machines, each drive machines being an electric machine and being allocated to a drive wheel. The method includes: acquiring a total setpoint drive torque; acquiring a current vehicle driving speed, a current steering angle, and optionally, the wheel loads of all drive wheels; determining wheel-individual movement speeds of the drive wheels over the roadway based on the current vehicle driving speed, the current steering angle, a known chassis geometry of the motor vehicle, and optionally, the wheel loads; determining a setpoint wheel speed for each drive wheel based on the determined movement speeds, and distributing the total setpoint drive torque to all drive wheels such that an actual curve path deviates from a setpoint curve path specified by the steering angle; actuating each drive machine to adjust the setpoint wheel speed at the respective drive wheel.

Method for operating a motor vehicle, control unit and motor vehicle

A method for operating a vehicle, in particular, a vehicle for highly automated driving. The method includes a step of reading in input data. The input data include sensor data and sensor state data of a multitude of sensor units of vehicle. The method also includes a step of generating a potential field, using the input data. The input data are used as attractive potentials and repulsive potentials of the potential field. The method furthermore includes a step of determining a trajectory through the potential field in order to generate a fusion signal, using the trajectory, for fusing the input data for a sensor data fusion for a highly automated driving operation of the vehicle.

Method and device for operating a vehicle

In a method for drive optimization in a motor vehicle including at least two drivable wheels at a vehicle axle having individually settable drive torque, to increase the propelling force, the drive torque at at least one wheel is increased in such a way that an increased longitudinal slip of at least 20% results at the wheel.

Method for drive optimization in a motor vehicle

A method for transferring the drive torque from the wheels having a low traction to the wheels having a higher traction, the method being configured for vehicles in which not all driven wheels are equipped with a rotational speed sensor. In order to be able to perform a starting aid function, it is provided to measure the rotational speed of the cardan shaft and to put it in relation to the wheel rotational speed of at least one wheel which has a rotational speed sensor. If the deviation between the cardan shaft rotational speed and the measured wheel rotational speed is too high, at least one of the wheels, which does not have a rotational speed sensor, is braked automatically so that the vehicle is able to start.
