Abstract

A process of providing driver fuel economy feedback is disclosed in which vehicle sensors provide for haptic feedback on fuel usage. Such sensors may include one or more of a speed sensors, global position satellite units, vehicle pitch/roll angle sensors, suspension displacement sensors, longitudinal accelerometer sensors, throttle position in sensors, steering angle sensors, break pressure sensors, and lateral accelerometer sensors. Sensors used singlely or collectively can provide enhanced feedback as to various environmental conditions and operating conditions such that a more accurate assessment of fuel economy information can be provided to the driver.

Claims

providing a vehicle having a plurality of environmental sensors including a temperature sensor, a pitch sensor, a roll angle sensor, a grade sensor, an altitude sensor and a payload sensor;

providing information from the plurality of environmental sensors to a controller including an environmental temperature in which the vehicle is operating, a vehicle angle of incline, a payload, and an altitude in which the vehicle is operating;

providing additional vehicle operation data to the controller;

determining theoretical maximum fuel efficiency under the conditions that the vehicle is experiencing based upon the information from the environmental sensors including the environmental temperature in which the vehicle is operating, the vehicle angle of incline, the payload, and the altitude in which an automotive vehicle is operating and the information of vehicle operation data;

following said step of determining the theoretical maximum fuel efficiency, providing sensory feedback in real time via the controller to a seat of the operator to inform the operator of behavior which has an adverse impact on the fuel economy of the vehicle based on a comparison of the maximum theoretical fuel efficiency to an actual fuel efficiency of the vehicle.

4. The process of claim 1, wherein the seat of the operator comprises a plurality of actuators in communication with the controller and wherein the providing sensory feedback via the controller to a seat comprises, actuating two or more actuators of the plurality of actuators via the controller to inform the operator of behavior which has an adverse impact on the fuel economy of the vehicle.

5. The process of claim 4, wherein the providing sensory feedback via the controller to a seat further comprises cycling two or more actuators of the plurality of actuators via the controller in different orders to be indicative of various conditions of which the operator is to be made aware.

6. The process of claim 1, wherein the providing sensory feedback via the controller to a seat further comprises varying an intensity of the sensory feedback to provide additional qualitative feedback to the operator.

7. The process of claim 1, wherein the additional information of vehicle operation data comprises acceleration rates and deceleration data from accelerometer sensors.

evaluating using a controller an actual fuel efficiency of the automotive vehicle compared to the maximum theoretical fuel efficiency;

relaying information in real time from the controller to a haptic seat engaged by an operator, the information being relayed only when actions controlled by the operator can improve a fuel efficiency of the automotive vehicle based on the evaluation of the actual fuel efficiency of the automotive vehicle compared to the maximum theoretical fuel efficiency.

9. A process of monitoring fuel economy of an automotive vehicle comprising:

determining vehicle operating conditions of the automotive vehicle via sensors including an environmental temperature in which the vehicle is operating, a vehicle angle of incline, a vehicle payload, and an altitude of the vehicle;

determining operator controlled parameters relative to a fuel efficiency of the vehicle;

calculating maximum theoretical fuel efficiency for the operating conditions of the vehicle including the operating temperature, the vehicle angle of incline, the vehicle payload, and the altitude of the vehicle;

comparing the maximum theoretical fuel efficiency to an actual fuel efficiency of the vehicle;

relaying information in real time from a controller on a qualitative evaluation of fuel efficiency to an operator using a sensory information haptic seat delivery system and delivering information from the controller only when changes to operator behavior can improve actual fuel efficiency based on the comparison of the maximum theoretical fuel efficiency to the actual fuel efficiency of the vehicle.
