Abstract
A dynamic safe state control circuit is disclosed that controls an electrical motor based on vehicle speed. A microcontroller or other processing device is configured to control an inverter system of an electrical motor. The dynamic safe state control circuit is configured to receive a first signal that corresponds to a speed of the electric motor. The circuit is configured to activate any one of a plurality of safe states in the inverter system based on the first signal and in response to a malfunction in the microcontroller.
