Title:
Hybrid type drive unit
Document Type and Number:
Japanese Patent JP6158126
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To solve the problem in which when an exhaust gas control device is mounted on a hybrid type driving device which achieves efficiency of driving by using the power of an electric motor and the power of an engine in combination, the fuel consumption gets worse as the regeneration frequency of the exhaust gas control device is higher.SOLUTION: A hybrid type driving device includes: a motor generator which functions as a power generator and an electric motor; a battery which connects with the motor generator; an engine; and an exhaust gas control device which purifies the exhaust gas of the engine. When an operation point Q1 associated with the rotating speed N and torque T of an object to be driven is on a low-torque side where the exhaust gas purification device cannot perform self-regeneration with the engine alone, the object to be driven is driven by the motor generator alone through an electric motor operation of the motor generator using the electric power of the battery.
