Vehicle transmission system control, limits engine torque on detection of defect in electronic or mechanical components of transmission system

摘要

The electronic engine control unit (132) measures signals related to the transmission system. It determines whether any functional problem (especially safety-related) exists in drive train components responsible for torque transmission, i.e. the clutch (114), clutch actuator (116), gears (102), gear change actuation unit (106), electronic gear selection unit (110) or the signal transmission path. The electronic engine controller (132) limits maximum permissible engine torque, should any defect be detected. An independent claim is included for the corresponding system.
