Abstract
An apparatus includes a deceleration definition module that interprets a target deceleration rate, a deceleration detection module that identifies a vehicle deceleration event, and a deceleration quality module that identifies a deceleration improvement opportunity in response to the target deceleration rate and the vehicle deceleration event. The apparatus further includes an operator feedback module that provides a specific operator guidance in response to the deceleration improvement opportunity.
