Abstract
Systems and methods for operating a hybrid vehicle during an end of assembly line test are presented. In one example, torque of an integrated starter/generator (ISG) is adjusted so that the ISG may not affect engine data that is collected during end of assembly line engine testing. The collected engine data may be a basis for adapting engine operation.
Claims20
A method for operating a driveline, comprising:
- adjusting a torque applied to the driveline via an electric machine in response a request for a neutral profile learning test request;
- increasing a speed of an engine in response to the request for the neutral profile learning test request;
- and
- deactivating engine fuel injectors in response to the request for the neutral profile learning test request.
1 more element
A system, comprising:
- an engine;
- an integrated starter/generator (ISG);
- a driveline disconnect clutch positioned in a driveline between the engine and the ISG;
- and
- a controller including executable instructions stored in non-transitory memory that cause the controller to adjust torque output of the ISG in response to a request for neutral profile learning.

A method for operating a driveline, comprising:
- adjusting a torque applied to the driveline via an electric machine while a transmission is engaged in park or neutral in response a request for a neutral profile learning test request;
- increasing a speed of an engine while the transmission is engaged in park or neutral in response to the request for the neutral profile learning test request;
- and
- deactivating engine fuel injectors while the transmission is engaged in park or neutral in response to the request for the neutral profile learning test request.
