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.
Claims18
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 phases of a gear shift, wherein the threshold pressure is a maximum clutch pressure;
- and
- adjusting operation of a device in response to the threshold pressure.
1 more element
A vehicle system, comprising:
- one or more torque sources;
- a transmission including a plurality of gear clutches and gears;
- a controller including executable instructions that cause the controller to:
- adjust a pressure supplied to the one of the plurality of gear clutches in response to a temperature estimate of the one of the plurality of gear clutches and a threshold temperature for the one of the plurality of gear clutches, where the threshold temperature is based on phases of a gear shift;
- and
- determine phases of a scheduled gear shift.
3 more elements
A method for operating a clutch, comprising:
- via a controller, integrating a variable over phases of a gear shift to generate a threshold temperature for the clutch;
- and
- adjusting operation of a device in response to a temperature of the clutch and the threshold temperature for the clutch.
