A method for controlling a vehicle driveline includes connecting an electric motor to each of respective vehicle wheels, determining from driver input a magnitude of demanded wheel torque, determining speed of each wheel, using demanded wheel torque and the respective wheel speed to determine from a power loss map a current power loss for each motor, and transmitting power from the motor having the lowest current power loss to the respective vehicle wheel.

Powertrain for electric vehicles

A method for controlling an electric vehicle drivetrain having least two drive units with wheels located on opposite axles are driven by respective drive units, includes in a first operating mode, the ratio of the torques provided by the drive units in each case for a given torque requirement is set taking into account the efficiency applicable to each drive unit under the given operating conditions, and in a second operating mode, the ratio of the torques provided by the drive units in each case for a given torque requirement is set independently of the efficiency applicable to each drive unit under the given operating conditions.

Method and device for controlling the drive train of an electric vehicle

In order to limit rolling movements of the vehicle, spring arms are formed on those ends of the leaf spring, arranged transversely to the vehicle, on which the wheel carriers are articulated, said spring arms being connected in a force-transmitting manner to the transverse leaf spring. The spring arms point toward the longitudinal mid-plane of the vehicle and run at an acute angle to the transverse leaf spring. Since the spring designed in this way is a universally available structural part (the spring arms running at an angle may also be produced separately and then be connected non-positively to the transverse leaf spring), the two wheels are connected to one another directly and the triangular shape formed by the spring arms running at an angle gives rise to a function similar to that of a transverse link.
