  • Patent number: 9815448
    Abstract: In a method for controlling a vehicle drive unit having at least two individual drives and a vehicle control unit, a continuous torque comparison between a permissible torque MZul and a further torque is performed by the control unit. The permissible torque MZul is continuously compared to setpoint torques Msetpoint,V and Msetpoint,E for the least two individual drives.

  • Patent number: 8433464
    Abstract: A method is provided for monitoring the torque distribution in multiple drive systems, e.g., in hybrid drives. The hybrid drive includes at least two individual drives which are controlled via an engine control unit, in which a torque distribution of a setpoint torque MSETPOINT to the at least two individual drives takes place. After the torque distribution, the formation of a resulting torque MRES takes place which is compared continuously with a torque before the torque distribution.

  • Patent number: 8219272
    Abstract: A method for controlling a vehicle drive unit, which comprises at least two individual drives, at least one of which is able to provide a negative torque. A vehicle control unit is provided, within which a continuous torque comparison is performed within a monitoring level. A permissible torque is ascertained therein. Using a torque range checker it is established whether ascertained setpoint torques lie within torque ranges of the at least two individual drives.

  • Patent number: 8169173
    Abstract: A method for controlling a vehicle drive unit, the vehicle drive unit having at least two individual motors. A total actual torque is continuously compared with an allowable total torque, the total actual torque being calculated from individual actual torque values of the at least two individual motors, and the allowable total torque being calculated from the allowable individual torque values of the at least two individual motors, and an error response being initiated if the comparison establishes that the total actual torque is greater than the allowable total torque.

  • Patent number: 8087484
    Abstract: A method for controlling a motor vehicle drive, in particular a hybrid drive, is provided, the motor vehicle drive having at least two individual motors. In a first method step, at least one total setpoint torque is calculated. In a second step, the at least one total setpoint torque is split into at least two individual setpoint torques of the at least two individual motors. Subsequently, in a first individual torque comparison step, the sum of the at least two individual setpoint torques is compared with the total setpoint torque. In the event of a difference by more than a predefined tolerance value, a limitation step is initiated. In this limitation step, the at least two individual setpoint torques are each multiplied by a limiting factor to generate at least two limited individual setpoint torques.

  • Patent number: 7877193
    Abstract: A method for operating a shutoff device for a device, in particular an internal combustion engine and/or an electric machine, in which an operating element for initiating a shutoff operation is provided, and in which a transmission path is provided via which a shutoff signal is transmitted from the operating element to the device in order to deactivate the device. The shutoff device is checked for proper functioning at least in part automatically, by automatically transmitting a shutoff signal, in particular from the operating element via the transmission path to the device.

  • Publication number: 20090204279
    Abstract: A method for monitoring torque in a hybrid drive made up of an internal combustion engine having an associated engine control unit and an intrinsically safe electric drive having an associated control unit, a protected communication taking place in which the engine control unit emits a setpoint torque to the control unit of the intrinsically safe electric drive and receives a status signal from it; and the engine control unit emitting an error signal in response to the exceeding of a permissible torque or in response to a negative status signal. If the intrinsic safety of the electric drive is used for the constant torque monitoring according to the specifications of the setpoint torque within the control unit, the data flow between the engine control unit of the internal combustion engine and the intrinsically safe electric drive may be reduced. As a result, the monitoring effort for the communication that is carried out in protected form between the engine control and the control unit is also reduced.
