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 Mand a further torque is performed by the control unit. The permissible torque Mis continuously compared to setpoint torques Mand Mfor the least two individual drives.

Method for simplifying torque monitoring, in particular for hybrid drives

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 Mto the at least two individual drives takes place. After the torque distribution, the formation of a resulting torque Mtakes place which is compared continuously with a torque before the torque distribution.

Method for simplifying torque distribution in multiple drive systems

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.

Method for monitoring multi-motor drive

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.

Method for controlling a vehicle drive unit

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.

Method for limiting setpoint torques during engine control

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.

Method for operating a shutoff device for a device, in particular an internal combustion engine and/or an electric machine, as well as a shutoff device

A method for monitoring a system, having a control unit defined as a master and a number of control units defined as slaves, with the aid of a monitoring module, in which in reply to an inquiry from the master and the slaves a response is given in each instance and a joint response provided on the basis of these responses is checked by the monitoring module.

Method for monitoring a system

In a motor vehicle having an internal combustion engine, an enabling condition is a function of at least one operating variable, of the motor vehicle and/or of the internal combustion engine. Starting and/or stopping of the internal combustion engine are enabled as a function of the enabling condition. It is provided that the presence of the enabling condition be checked redundantly within the scope of a 3-level monitoring concept.
