Abstract

This engine-start control device is provided with: an engine control unit; a motor control unit; and a control unit for controlling the engine control unit and the motor control unit. In cases when an engine restart control mode is to be shifted from a motoring control state to a fuel-combustion control state, the control unit performs this shift via a motor / engine cooperative control state, and sets the timing at which the engine restart control mode is shifted from the motoring control state to the motor / engine cooperative control state, as the timing at which the crank angle in the initial cylinder to have fuel combust therein after injection of the fuel has started reaches the estimated crank angle at which torque is generated by the initial fuel combustion.

Description

technical field [0001] The invention relates to an engine start control device, in particular to an engine start control device for a vehicle with an idle stop function. Background technique [0002] The idling stop vehicle stops fuel supply to the engine when a preset idling stop condition is satisfied. Therefore, after the engine speed drops, the engine stalls. Thereafter, when the brake pedal is released or the like, the electric motor directly connected to the engine shaft starts to rotate, and the engine restarts state in which the engine speed increases. Afterwards, when a predetermined condition is satisfied, fuel injection is restarted, the drive of the electric motor is stopped, and the engine is rotated only by energy generated by fuel combustion. During the engine restart state, the torque transmitted to the vehicle is controlled using the driving force of the electric motor and energy generated by fuel combustion. However, if the controllability is lowered, th...
