Abstract
A method and system for estimating a temperature of a clutch and a maximum temperature of a clutch are described. In one example, the maximum temperature of the clutch is based on phases of a transmission gear shift. The transmission gear shift may include a power-on downshift and a power-on upshift.
Claims20
A method for operating a clutch, comprising:
- via a controller, generating an estimate of a temperature of the clutch;
- generating a threshold pressure for the clutch based on one or more phases of a gear shift;
- and
- adjusting operation of the clutch in response to the threshold pressure.
1 more element
A vehicle system, comprising:
- one or more torque sources;
- a transmission including a plurality of clutches and a plurality of gears;
- and
- a controller including executable instructions that cause the controller to:
- adjust a pressure supplied to the one of the plurality of clutches in response to a temperature estimate of the one of the plurality of clutches and a threshold temperature for the one of the plurality of clutches, where the threshold temperature is based on one or more phases of a gear shift;
- and
- determine phases of a scheduled gear upshift or a schedule gear downshift.
4 more elements
A method for operating a clutch, comprising:
- via a controller, generating a threshold temperature for the clutch based on a heat power of the clutch during one or more phases of a gear shift;
- and
- adjusting operation of the clutch in response to a temperature of the clutch and the threshold temperature for the clutch.
