  • Patent number: 8423216
    Abstract: To provide an engine controller of a hybrid vehicle that can perform a forced driving operation of an engine by performing the same inspection procedure as that of a vehicle using only an engine as a drive source even in the hybrid vehicle. The engine controller includes an operation control unit (ECM) that performs forced driving control of the engine to maintain an operation in a predetermined state suitable for an inspection if a determination that the inspection of the engine by a forced driving operation is requested is made, and an operation state determination unit (EVCM) that determines whether the cold start condition is satisfied or unsatisfied based on information containing at least with or without change from the disconnected state to the connected state of the battery. If the cold start condition is satisfied, the forced driving control of the engine is performed by the operation control unit.

  • Patent number: 6389916
    Abstract: A control device for a synchromesh automatic transmission comprising an input shaft 13 coupled to a crank shaft 1a of a combustion engine 1 by a clutch 2, an output shaft 16 coupled to the input shaft 13 by gears, a plurality of groups of transmission gears located between the output shaft 16 and the input shaft 13, sleeve gears selectively coupling one of the groups of the transmission gears to the output shaft 16, a shifting and selecting actuator 5 operating the sleeve gears 22, a shifting and selecting position sensor 6 detecting operating positions by the shifting and selecting actuator 5, and a control unit controlling a control input to the shifting and selecting actuator 5, wherein the control unit corrects a next target control input using a deviation between an actual control input to the shifting and selecting actuator 5 and a target control input as a learning value, whereby a shifting operation is constantly conducted within a short time even though a shifting quantity is changed by an aged deter
