Patent number: 7664580Abstract: A method for operating power train side components of a motor vehicle. Using a control device of a motor, at least one motor parameter is issued and delivered via a databus to at least one control device of one other power drive side component working independently of the motor control device in order to operate all or each one of the power drive side components dependent. in a first inventive aspect, a behavior of the respective other power drive side components that adjusts itself according to the motor torque actually made available by the motor is evaluated. In second inventive aspect, the motor torque issued by the motor control device is compared with a torque stored according to motor operation parameters in the control device working independently of the motor control device.Type: GrantFiled: October 17, 2006Date of Patent: February 16, 2010Assignee: ZF Friedrichshafen AGInventors: Christian Popp, Georg Gierer, Thilo Schmidt, Klaus Steinhauser, Peter Schiele, Bernd Allgaier, Christian Schwemer, Ruben Cüppers
