Title:
AUTOMOBILE AND CONTROL DEVICE FOR AUTOMOBILE
Document Type and Number:
Japanese Patent JP3956937
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To improve ride comfort by switching to control for suppressing unusual noise and vibration of an engine by an instruction from a driver.
SOLUTION: In an automobile in which an engine, a motor MG1 and a driving shaft are connected to a planetary gear and a motor MG2 is connected to the driving shaft through the medium of a reduction gear, while a EGR amount established by engine rotating speed and intake air quantity is reduced by being multiplied by a correction coefficient when a NV switch is on-operated, the rotation speed and torque at an intersection point of a target power Pe* to be outputted from the engine and an action line for ride comfort set by avoiding a low-rotation high-torque region in an action line for fuel consumption to a low-torque side are taken as the target rotation speed Ne* and the target torque Te* so as to control the engine and two motors. By so doing, unstable combustion by torque pulsing and EGR generated by operating the engine at the low-revolution high-torque region can be suppressed. As a result, unusual noise and vibration can be suppressed to improve ride comfort.
