First Claim
Patent Images
1. A method for operating a vehicle, the method comprising:
- applying a test signal to a vehicle electric power component;
generating a response from the component;
determining an operating state of the component based at least in part on the response to the signal; and
controlling vehicle operation based at least in part on the determined operating state of the component.

Abstract
A prognostic method and system for testing and controlling various hybrid, fuel cell, and electric vehicle components. The tests generate test data for determining a state of the tested components. An operating strategy of the vehicle is controlled based on the state of its tested components.

19. A system for controlling operation of an electronic power component of a vehicle based at least in part on a determined state of the vehicle component, the system comprising:
-
a prognostic module to diagnose the state of the vehicle component by providing a test signal thereto and determining a degrading state of the tested component based at least in part on a response of the tested component to the test signal if the determined state is degrading faster than a predefined degradation rate; and
a vehicle system controller for controlling operation of the vehicle, the vehicle system controller being operable with the prognostic module to limit vehicle operation in response to detection of a degrading state of the tested component. - View Dependent Claims (20)
