Zusammenfassung: | PURPOSE: To speedily increase braking torque of an engine by comparing the number of revolutions of the engine and the number of input and output rotation of a transmission with a plurality of threshold values to trigger a shift down switching process of the transmission when engine brake of a motor vehicle is applied. CONSTITUTION: The number of revolutions of an engine Mmot and engine torque Nmot are outputted from an internal combustion engine 11 to a converter 12. Moreover, the number of revolutions of a transmission NF is outputted from the converter 12 to the transmission 13 so that the number of output rotation Nab of the transmission 13 acts on drive wheels of a motor vehicle 14. Furthermore, braking torque MB by the operation of the internal combustion engine 11 is outputted on an output side of the transmission 13 so that it acts on the drive wheels of the motor vehicle 14. Gear shift ratios S differing from each other are selected and outputted from a control unit 15 to the transmission 13, and fuel/air mixture amount QL/QK is outputted from the control unit 15 to the internal combustion engine 11. On the other hand, a pedal position FP is outputted from an accelerator pedal 16 to the control unit 15. |
