Method and apparatus for adaptive control and protection of hybrid electric vehicle systems
First Claim
1. A method for adaptively controlling a hybrid electric vehicle including an energy generation system, an energy storage system receiving electric current at least from the generation system, and at least one electric drive motor receiving current from the energy storage system, comprising:
- monitoring the status of various vehicle systems;
determining if each system status is within a safe operating range predetermined for that system;
determining an appropriate action necessary to return each non-safe operating system to a safe operating range or to protect each non-safe operating system or vehicle from further damage if each non-safe operating system cannot be returned to a safe operating range;
generating command signals to each non-safe operating system or to other systems to return each non-safe operating system to a safe operating range;
determining if all systems have returned to a safe operating range;
generating command signals to each remaining non-safe operating system or to other systems to isolate and disable each non-safe operating system that has not returned to a safe operating range.

Abstract
A hybrid electric vehicle having an energy generation system, an energy storage system and at least one electric motor includes a controller for controlling operation of vehicle systems. The controller monitors the status of vehicle systems and system parameters and determines if all systems are operating within predetermined safe operating ranges. The controller generates commands based upon these determinations to disconnect and isolate systems that exceed safe operating ranges, and to modify or change operating commands sent to other systems to compensate for the isolated system or systems. The controller also generates commands to place system components into a safe configuration or state in shutdown or failure events so as to protect the vehicle and maintenance personnel from potential damage or injury. A method of adaptively controlling a hybrid electric vehicle is also provided.
