<p>PURPOSE:To make possible the engine brake control in which the fuel consumption is improved, and the chattering shock is prevented, when power-OFF is operated from a power-ON lock-up state. CONSTITUTION:A power train is constituted of an engine 1, torque converter 2, and an automatic transmission 3, and a transmission controller 5 is installed for the engine brake control for the automatic transmission 3, and an engine controller 12 is installed for the engine fuel cut control. The transmission controller 5 performs engine brake control by receiving each signal showing the number Ne of revolution of engine output shaft, number Nt of revolution of a turbine, number No of revolution of a transmission output shaft, car speed Vsp, and the engine throttle signal Tvo and the idle switch state signal Sidle, and inputs the fuel cut permission signal FCper into the engine controller 12, and the engine controller 12 performs the engine fuel cut control according to the fuel cut permission signal.</p> |
