A coupling device and a coupling mechanism is provided for selectively coupling of an electric drive to a wheel axle of a vehicle. The coupling device includes, but is not limited to an output gear connected to the wheel axle, an input gear connected to the electric motor. A synchronizer is adapted to contactlessly minimize a difference of the input gear's and the output gear's angular velocity below a predefined threshold, and a synchronizing member is adapted to frictionally engage with the input gear and/or with the output gear when the difference in angular velocity of input gear and output gear is below the predefined threshold.

Coupling and synchronizing device for electric drive modules

A drive unit, more preferably rear drive unit, for an all-wheel drive of a motor vehicle with two drive shafts, of which one drive shaft serves for driving the one wheel and the other drive shaft serves for driving the other wheel of a motor vehicle. Provided is a transmission operationally that is connected to the drive shafts, through which a drive torque acting on the input of the transmission can be divided or is divided into at least two output torques and through which the output torque of the transmission acting on the one drive shaft is reversible or is reversed in its operation direction relative to the output torque of the transmission acting on the other drive shaft.

Drive unit, particularly rear drive unit, for an all-wheel drive of a motor vehicle

A vehicle () comprises sensor units () for collecting sensor data, and a processing unit () for processing the sensor data. A method of providing driving assistance information comprises the steps of: determining the cost (c) of pairs () of acceleration values on the basis of the sensor data, each pair of acceleration values representing a longitudinal (a lon) and a lateral (a lat) acceleration of the vehicle, &#x2014;selecting a pair () of least cost acceleration values, and&#x2014;providing driving assistance information including the pair of least cost acceleration values. The processing unit () may be arranged for providing visible, audible and/or haptic driving assistance information to the driver of the vehicle, and/or for providing steering assistance.
