1. A system for a hybrid vehicle driver by an operator, comprising:
- an energy storage device;
a regenerative braking system coupled to the energy storage device;
a dissipative braking system coupled to the vehicle;
a brake lever;
a haptic operator interface; and
a control system for operating one or both of the regenerative and dissipative braking system in response to actuation of the brake lever; and
providing feedback to the operator through the haptic interface differentiating a type of braking operation.

17. A method of controlling a hybrid vehicle having regenerative and dissipative braking ability, the vehicle operated by an operator, comprising:
-
during a first level of driver braking actuation, applying regenerative braking without dissipative braking to brake the vehicle and providing an indication of such to the operator; during a second level of driver braking actuation, applying dissipative braking and providing an indication of such to the operator, where said second level is greater than said first level at least during one condition. - View Dependent Claims (18, 19, 20)

21. An aftermarket apparatus for providing coaching feedback to an operator of a vehicle that will encourage the vehicle to be driven with high fuel economy, comprising:
-
a haptic actuator for providing feedback to the vehicle operator, said haptic actuator including a mounting to facilitate installation on a brake control assembly of said vehicle; an interface having a plurality of fuel savings settings of increasing fuel economy in addition to a setting without said coaching feedback; and a haptic controller enclosed in a housing having a first interface for connecting to a diagnostic port of said vehicle and a second interface for communicating with said interface, said haptic controller having a programmed instruction set for causing said haptic actuator to provide coaching feedback to said operator differentiating between at least regenerative and dissipative braking of the vehicle.
