    Abstract: A vehicle control system may include a brake pedal position sensor, a braking torque module, an accelerator pedal position sensor, and a brake augmenter. The brake pedal position sensor is operably coupled to a brake pedal to determine a brake pedal position responsive to actuation of the brake pedal by an operator. The braking torque module is operably coupled to wheels of the vehicle to provide negative torque to the wheels based on the brake pedal position when an EBB system is in an operable state. The accelerator pedal position sensor is operably coupled to an accelerator pedal to determine accelerator pedal position for generation of positive torque to the wheels based on the accelerator pedal position when the EBB system is in the operable state. The brake augmenter is operably coupled to the accelerator pedal position sensor to provide a negative torque input to the wheels responsive to the accelerator pedal position sensor indicating a first range of pedal positions and a positive torque input to the wheels responsive to the accelerator pedal position sensor indicating a second range of pedal positions when the EBB system is in an inoperable state.

    Abstract: A vehicle regenerative braking control system includes a brake pedal; a brake pedal angle sensor interfacing with the brake pedal; a vehicle braking system interfacing with the brake pedal angle sensor, the vehicle braking system adapted to implement friction braking and regenerative braking responsive to receiving a brake pedal angle input signal from the brake pedal angle sensor; and at least one of a brake pedal switch and a brake master cylinder pressure sensor interfacing with the brake pedal and the vehicle braking system. The vehicle braking system is further adapted to implement friction braking and regenerative braking responsive to input from the at least one of a brake pedal switch and a brake master cylinder pressure sensor in the event that the vehicle braking system does not receive the brake pedal angle input signal from the brake pedal angle sensor. A regenerative braking control method is also disclosed.

    Abstract: A vehicle control system may include a brake module operably coupled to a braking system of the vehicle to provide a braking torque request to the braking system, a steering module operably coupled to a steering system of the vehicle to provide a steering input request to the steering system, a power supply, and a power management module. The power supply may be operably coupled to the brake module and the steering module to provide power to the brake module and the steering module. The power supply may have a power budget indicating a maximum power providable to the brake module and the steering module. The power management module may be operably coupled to one or more sensors to receive a power draw indication from one of the brake module or the steering module and control power draw of the other of the steering module or the brake module to maintain a combined power draw of the brake module and the steering module below the power budget.
