  • Patent number: 10449965
    Abstract: A driver assistance device for a motor vehicle with a drive assembly, which can be connected to a drivetrain via a clutch that can be activated by an actuator. The clutch being a component of an electronically controlled clutch system, in which a clutch pedal sensor detects an actuation of a clutch pedal on the driver's side and in which an analysis unit determines, in a first control mode on the basis of the detected clutch pedal actuation, a clutch torque and actuates the clutch with a corresponding clutch signal. For an adjustment of the clutch response on the driver's side, the analysis unit is associated with an input unit, for the actuation of which, on the driver's side, it is possible to shift between the first control mode and at least one second control mode.

  • Publication number: 20190160967
    Abstract: A method for operating a motor vehicle. The motor vehicle has an electric traction machine. In a first kind of operation of the motor vehicle, before or during a release of a parking brake of the motor vehicle when the motor vehicle is at a standstill, a desired rotational speed for a rotational speed regulation of the traction machine is set to a value corresponding to the standstill of the motor vehicle, and an actual rotational speed of the traction machine is adjusted to the desired rotational speed.

  • Patent number: 9914459
    Abstract: A method for controlling a drive of a vehicle with at least one first axle having at least one mounted wheel. A drive torque is specified by a driver of the vehicle, and the first axle is driven by means of a first electric machine dependent on the drive torque. A second electric machine which is coupled to an internal combustion engine provides electrical energy for driving the first axle with the first electric machine. A respective control or target torque assigned to the second electric machine and the internal combustion engine is computed while taking into consideration the drive torque and machine parameters of at least the second electric machine. The second electric machine and the internal combustion engine are each regulated with respect to the assigned control torque or with respect to the assigned target torque.

  • Patent number: 9827866
    Abstract: A drive device of an at least partially electrically operated vehicle includes at least two vehicle wheels, each wheel being mechanically coupled to an electrical drive unit. Each electrical drive unit obtains electrical energy from an electrical energy storage device during motor operation, and/or supplies the electrical energy storage device with electrical energy during generator operation. When operating as intended, the electrical drive units provide a torque according to a drive-unit-specific torque of a vehicle control system. A maximum total torque is determined by taking into consideration a maximum available output of the electrical energy storage device, wherein the sum formed of the drive-unit-specific torques is limited using the maximum total torque.

  • Patent number: 9789864
    Abstract: A hybrid manager control unit for a drive train of a vehicle, wherein the hybrid manager control unit has a total target torque dividing device for optimizing an efficiency by dividing a total target torque specification into a first axle torque specification for a first axle of the vehicle and a second axle torque specification for a second axle of the vehicle. The hybrid manager control unit has a redistributing device for producing a first and a second redistributed axle torque specification by partially or completely redistributing the first or the second axle torque specification to the second redistributed axle torque specification or to the first redistributed axle torque specification while taking into account at least one driving dynamics parameter. A vehicle includes a hybrid manager control unit for a drive train of a motor vehicle and a method for distributing a total target torque specification for a vehicle.

  • Publication number: 20170267228
    Abstract: A method for producing a floorboard having a topside veneer includes forming a multilayer body which includes a starting carrier plate, a plurality of veneers placed on the starting carrier plate so that a gap is formed between neighboring ones of the veneers, a resin layer comprising a resin provided between the starting carrier plate and the veneers, and a balancing layer arranged on a bottom side of the starting carrier plate; joining the starting carrier plate, the resin layer, the veneers and the balancing layer by pressing the multilayer body in a press; separating the multilayer body into individual boards between the neighboring veneers in a region of the gap; profiling the individual boards at side borders of the boards; and providing the individual boards with joining means.

  • Patent number: 8328680
    Abstract: A motor vehicle having a drive train and a motor unit which can be coupled to the drive train, and at least one electric machine. A freewheel mode is activated to increase the energy efficiency so that the motor vehicle is neither powered nor decelerated by the motor unit, thus allowing the wheels of the motor vehicle to essentially roll freely. In the freewheel mode, the electric machine is operated as a motor which introduces a freewheel mode pull torque to the drive train.
