Abstract: A PCM (50) that is an engine control device functions to acquire a master vac negative pressure which is the negative pressure of a stabilized chamber of a master vac (126) which amplifies a brake pedal depressing force applied to a brake pedal (102), and also acquire a brake working fluid pressure that is a braking hydraulic pressure produced by a master cylinder (144) in accordance with the brake pedal depressing force amplified by the master vac (126), and in a case where both accelerator pedal (104) and a brake pedal (102) are depressed or actuated simultaneously, determine whether or not it is necessary to decrease engine output based on such master vac negative pressure and brake working fluid pressure to execute the output decreasing control for decreasing the engine output.

Abstract: An engine control device to be mounted on a vehicle is provided. The control device includes a transmission state determining module for determining a connection between a stepped transmission and an engine, determining that a gear shift has started if the connection is disengaged from a connected state, and determining that the gear shift has finished if the connection is resumed, a gear position estimating module for estimating a gear position when the gear shift is determined to have started, a target engine speed specifying module for specifying a target engine speed based on the estimated gear position, and a speed control module for controlling an engine speed to the target engine speed when the gear shift is determined to have started.
