Control apparatus for hybrid vehicle
First Claim
1. A control apparatus of a hybrid vehicle, the hybrid vehicle having a first clutch which is arranged between an engine and a motor/generator and is in a disengaged state by being supplied with a hydraulic fluid and a second clutch which is arranged between the motor/generator and driving wheels and is in an engaged state by being supplied with the hydraulic fluid, the control apparatus comprising:
- a line pressure controller that controls a line pressure of the hydraulic fluid supplied to the first and second clutches; and
a drive mode controller that changes a drive mode between an HEV mode in which the first clutch is engaged and the vehicle travels with the engine and the motor/generator being a power source and an EV mode in which the first clutch is disengaged and the vehicle travels with only the motor/generator being the power source, andthe line pressure controller setting the line pressure in the HEV mode to a pressure level required for the engagement of the second clutch and setting the line pressure in the EV mode to a higher line pressure than the line pressure in the HEV mode.

Abstract
A control apparatus of hybrid vehicle having a first clutch which is in a disengaged state by being supplied with hydraulic fluid and a second clutch which is in an engaged state by being supplied with the hydraulic fluid, has a line pressure controller controlling a line pressure of the hydraulic fluid, and a drive mode controller changing a drive mode between HEV mode in which the first clutch is engaged and the vehicle travels with the engine and the motor/generator being a power source and EV mode in which the first clutch is disengaged and the vehicle travels with only the motor/generator being the power source. The line pressure controller sets the line pressure in HEV mode to a pressure level required for the engagement of the second clutch, and sets the line pressure in EV mode to a higher line pressure than the line pressure in HEV mode.

13. A method for controlling a line pressure of a hydraulic fluid for a hybrid vehicle, the hybrid vehicle having a first clutch which is arranged between an engine and a motor/generator and is in a disengaged state by being supplied with the hydraulic fluid and a second clutch which is arranged between the motor/generator and driving wheels and is in an engaged state by being supplied with the hydraulic fluid, the hybrid vehicle further having the following drive modes;
- an HEV mode in which the first clutch is engaged and the vehicle travels with the engine and the motor/generator being a power source and an EV mode in which the first clutch is disengaged and the vehicle travels with only the motor/generator being the power source, the method comprising;
setting the line pressure in the HEV mode to a pressure level required for the engagement of the second clutch, and setting the line pressure in the EV mode to a higher line pressure than the line pressure in the HEV mode. - View Dependent Claims (14, 15)
- an HEV mode in which the first clutch is engaged and the vehicle travels with the engine and the motor/generator being a power source and an EV mode in which the first clutch is disengaged and the vehicle travels with only the motor/generator being the power source, the method comprising;
