1. A vehicle regenerative braking control system, comprising:

  • at least one controller comprising computer instructions stored in non-transitory memory, the at least one controller configured to implement friction braking and regenerative braking responsive to input from at least one of a brake pedal switch and a brake master cylinder pressure sensor as backup inputs causing the at least one controller to implement parallel regenerative braking and friction braking in the absence of a brake pedal angle input signal from a brake pedal angle sensor, the at least one controller configured to receive a brake pedal angle sensor signal from the brake pedal angle sensor including through an initial range of motion of the brake pedal corresponding to traversal of a brake pedal gap, the absence of the brake pedal angle input signal further causing the at least one controller to implement only friction braking during traversal of the brake pedal gap, the at least one controller further configured to apply series regenerative braking during traversal of the brake pedal gap and apply parallel regenerative braking and friction braking following traversal of the brake pedal gap if the brake pedal angle sensor signal is available.
