1. A vehicle control system of a vehicle, the system comprising:
a brake pedal position sensor operably coupled to a brake pedal to determine a brake pedal position responsive to actuation of the brake pedal by an operator of the vehicle;
a braking torque module operably coupled to one or more wheels of the vehicle to provide negative torque to the one or more wheels based on the brake pedal position when an electronic brake boost (EBB) system of the braking torque module is in an operable state;
an accelerator pedal position sensor operably coupled to an accelerator pedal to determine accelerator pedal position for generation of positive torque to provide to the one or more wheels based on the accelerator pedal position when the EBB system is in the operable state; and
a brake augmenter operably coupled to the accelerator pedal position sensor to provide a negative torque input to the one or more wheels responsive to the accelerator pedal position sensor indicating a first range of pedal positions and a positive torque input to the one or more wheels responsive to the accelerator pedal position sensor indicating a second range of pedal positions when the EBB system is in an inoperable state.
