1. A computer-implemented method of reducing electrical current in vehicle braking for power conservation, the method comprising:
applying a first electrical current to a braking system of a vehicle after the vehicle has ceased movement on a slope, the first electrical current preventing the vehicle from moving on the slope;
determining a first braking pressure based on the first electrical current and the slope;
determining a second electrical current based on the first braking pressure and a braking hysteresis, wherein the second electrical current is lower than the first electrical current; and
reducing the first electrical current to the second electrical current in the braking system.
