MOTOR CONTROL DEVICE FOR VEHICLE HAVING DECELERATION DEACTIVATABLE ENGINE

摘要

A motor controller of a deceleration idling-cylinder engine vehicle idling a part of cylinders when the vehicle decelerates and driving a motor when an operation is moved from a deceleration idling-cylinder operation to a normal operation, comprising an idling-cylinder state discrimination means (S202) f or judging whether the engine is in the state of idling or not, an idling- cylinder execution means for executing the idling-cylinder operation of the engine, an idling-cylinder operation detection means (S201) for detecting th e operation or non-operation of the idling-cylinder execution means, and start torque set means (S201 to S204) for setting an engine start torque by the motor, wherein the start torque set means sets the motor start torque lower than a normal start torque when the engine is detected by the idling-cylinde r state discriminating means to be in the idling-cylinder state and judged by the idling-cylinder operation detection means that the engine tries to retur n to the normal operation, whereby the output of the motor can be optimally se t when the operation is moved from the deceleration idling-cylinder operation to the normal operation to smoothen the operation and improve a fuel consumptio n.
