Abstract:
A controller for an electric vehicle having an electric motor is provided. The controller includes a motor control processor (MCP) module configured to control torque output of the electric motor. The controller also includes a first main processor monitor (MPM) module and a second MPM module. The first MPM module and the second MPM module are configured to separately determine a state of health of the MCP module, and to generate a first fault signal and a second fault signal, respectively, after determining the MCP module is not functional. The controller further includes a voting control module configured to receive at least one of the first fault signal from the first MPM module, and the second fault signal from the second MPM module, and to generate an override command when it receives both the first fault signal and the second fault signal. The override command overrides the MCP module.
