Title:
ハイブリッド車両の制御装置
Document Type and Number:
Japanese Patent JP5601964
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve fuel economy by reducing drag friction torque caused by excessive hydraulic fluid accumulated inside a transmission.SOLUTION: A control device of an FR hybrid vehicle includes: an engine Eng; a motor/generator MG; a first clutch CL1; an automatic transmission AT; a line pressure indication value generation block 30; and a line pressure solenoid 23. The line pressure indication value generation block 30 includes an "HEV mode" obtained by fastening at least the first clutch CL1, and an " EV mode" obtained by opening the first clutch, and based on a minimum necessary line pressure set for each operation of the system modes, and generates a line pressure indication value. The line pressure solenoid 23 controls a line pressure PL which is a basic fluid pressure of the first clutch and the automatic transmission AT according to the line pressure indication value.
