  • Patent number: 6932741
    Abstract: An engine control device (20) for a vehicle has a torque control mechanism (17) for regulating the engine output torque. The torque control mechanism (17) includes at least one of a throttle valve (11) and a fuel injector (12). The engine control device further has a sensor (10) for detecting the shift lever position and a controller. The controller is configured to detect a shift in the shift lever position from the stationary range position (N or P range) to the running range position (D or R range) based on the shift lever position; and transmit a command signal to the torque control mechanism (17) when a first predetermined period elapses after the detection of the shift in the shift lever position, the command signal increasing the engine output torque by a predetermined correction gain ?Te from a first output torque Te0 at the detection of the shift lever position to a second output torque Te1.
