Patent ID: 6932741

Claim:
An engine control device for a vehicle, the vehicle having an engine, an automatic transmission receiving an output torque of the engine, a drive shaft for transmitting an output torque from the automatic transmission to the vehicle wheels and a shift lever for selecting the operating range of the automatic transmission; wherein the operating range of the automatic transmission includes a stationary range in which the engine output torque is not transmitted to a side of the drive shaft and a running range in which the engine output torque is transmitted to the side of the drive shaft, and a shift lever position includes a stationary range position corresponding to the stationary range of the automatic transmission and a running range position corresponding to the running range of the automatic transmission; the engine control device comprising: a torque control mechanism for regulating the engine output torque, the torque control mechanism including at least one of a fuel injector for injecting fuel and a throttle valve for regulating an intake air amount to the engine; a sensor for detecting the shift lever position; and a controller comprising a microcomputer; the controller being programmed to: detect a shift in the shift lever position from the stationary range position to the running range position based on the shift lever position; and transmit a first command signal to the torque control mechanism 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 from a first output torque at the detection of the shift lever position to a second output torque.
