1. A method for determining a fault state in a vehicle brake system, the method including:
receiving a brake pedal position signal from a brake pedal position sensor that indicates a driver intent to brake;
receiving a brake pedal force signal from a brake pedal force sensor disposed within the brake pedal;
receiving a vehicle braking response condition signal from a brake system feedback sensor for at least one vehicle wheel of a vehicle;
determining, with an electronic processor, based on the brake pedal position signal and the vehicle braking response condition signal, that the vehicle brake system is in a fault state when (1) the brake pedal position signal is indicative of no brake pedal movement and the vehicle braking response condition signal is indicative of a vehicle braking response occurring, or when (2) the brake pedal position signal is indicative of brake pedal movement and the vehicle braking response condition signal is indicative of no occurrence of a vehicle braking response;
providing an engine state signal or a motor state signal from an engine state sensor or a motor state sensor to the electronic processor; and
providing at least one selected from a group consisting of: a visual or audio indicator indicating the fault state, and controlling operation of the vehicle in response to the fault state.
