1. A regenerative braking system for a vehicle, comprising:
- a control module that receives one or more signals based on a vehicle environment and that generates a set speed and a control signal based on the one or more signals and the control signal represents a motoring mode and a generating mode; and
a motor control module that controls bidirectional current flow between an electric motor and a battery based on the control signal, wherein the motor control module controls the direction and magnitude of the current flow based on the control signal and the electric motor provides a decelerating load that slows an actual speed of the vehicle to the set speed.

Abstract
A regenerative braking system for a vehicle includes a control module that receives one or more signals based on a vehicle environment and that generates a set speed and a control signal based on the one or more signals. The control signal represents a motoring mode and a generating mode. A motor control module controls bidirectional current flow between an electric motor and a battery based on the control signal. The motor control module controls the direction and magnitude of the current flow based on the control signal and the electric motor provides a decelerating load that slows an actual speed of the vehicle to the set speed.
