An apparatus is disclosed that includes a haptic actuator operatively
associated with a pedal assembly of the vehicle, a human-machine
interface (HMI) for enabling the driver to select between a plurality of
fuel savings settings, and a controller coupled to a data interface in
the vehicle and the HMI interface for causing the haptic actuator to
provide feedback to the driver when an aspect of vehicle operation
crosses at least one of a plurality of speed and acceleration thresholds
responsive to the HMI setting. Additionally, a coaching method provides
haptic-based feedback that will not interfere with the operation of the
vehicle. This method of closed-loop feedback provides a timely signal to
the driver in a way that will encourage a change in driver style over
time, such as backing off the accelerator pedal to accelerate at a lower
rate and braking earlier with less intensity. As not all driver
preferences are the same under all conditions, the HMI selector will help
coach the driver by providing feedback that best fits their driving
preference at the particular time.
