Abstract: A method to control an electro-mechanical transmission mechanically-operatively coupled to an internal combustion engine and first and second electric machines to transmit power to an output member includes determining motor torque constraints and battery power constraints. A preferred output torque to an output member is determined that is achievable within the motor torque constraints and is achievable within a range for a first torque input and is achievable within a range for a second torque input and is based upon the battery power constraints.

Abstract: A drive authorization system for an electric drive includes a predefined number of field coils and a rotationally movable element. An evaluation and control unit for operation of the electric drive determines the current position of the movable element from several items of positional information, which can be made available by a predefined number of angle of rotation sensors. To implement an electronic immobilization function, positions, the number of the active rotation angle sensors, or both those positions and that number are made encodable. The evaluation and control unit decodes the encoded positional information of the active rotation angle sensors in order to determine the current position of the movable element. Operation of the electric drive is possible only after successful decoding of the positional information.

Abstract: A method serves for discontinuously emptying a container in which liquid collects. The container is emptied via a valve or other such emptying device. The container must never be completely emptied and never overflow. A sensor is arranged in the container to detect a first state in which liquid is present in a predetermined region and a second state in which no liquid is present in the predetermined region. The valve or other emptying device is activated as soon as the sensor detects the first state, and is stopped as soon as the sensor detects the second state.

Abstract: A method is provided for operating an active chassis system, in which wheels of at least one axle are arranged with a toe-in angle, and actuating elements which interact with supporting assemblies which are arranged between the wheels and a vehicle body. Wheel contact forces of the wheels assume different values as a result of the actuating elements being actuated. A side force is generated at the wheels which have a toe-in angle, and a resulting yaw moment is produced. A desired yaw rate is determined based upon information from a device which is arranged in the vehicle in order to determine the profile of the roadway in a control unit, and the wheel contact forces are set as a function of the desired yaw rate.
