    摘要： 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.

    摘要： The invention relates to a method for the continuous torque monitoring of a hybrid drive composed of an internal combustion engine with an engine control unit and an inherently safe electric drive with a control unit, wherein a permissible total torque is compared with the sum of an actual torque of the electric drive and an actual torque of the internal combustion engine. If the permissible total torque is reduced by the actual torque of the electric motor and is formed by a permissible torque of the internal combustion engine, it is largely possible by means of this method for existing software to be utilized further, and said software need not be amended. In the engine controller, it is largely possible for calculations to be carried out with torques which are normalized to the maximum torque of the internal combustion engine. In the comparison stage in particular, the value range of the torques in the case of a hybrid drive in relation to that in the case of a pure internal combustion engine is maintained. Storage-space-saving and calculation-duration-saving programming is therefore possible.
