REGENERATIVE BRAKING AND CHARGE FLOW STATE INDICATION SYSTEM FOR A HYBRID ELECTRIC VEHICLE
First Claim
1. An information display system for a vehicle including an engine and an electric machine, each operable to provide torque to propel the vehicle, the vehicle further including an electric power source configured to provide electric power to the electric machine, the information display system comprising:
- an information display configured to display a regenerative braking indicator; and
a controller being configured to receive regenerative braking information corresponding to a regenerative braking system, the controller further being configured to determine a regenerative braking state based upon the regenerative braking information, and the controller further being configured to transmit the regenerative braking state so that the information display displays the regenerative braking indicator that corresponds to the regenerative braking state.

Abstract
A system and method for using an information display to display information relating to a state of charge of the battery, a charge flow state of the battery, and a regenerative and friction braking system. The information display displaying the state of charge information that corresponds to the available energy capacity of the battery as a percentage of the total rated capacity of the battery. The information display displaying the charge flow state information that corresponds to a negative and positive charge flow state of the battery. The information display also displaying when the vehicle is operating the regenerative braking system or when the vehicle is operating the regenerative braking system and the friction braking system.
