Abstract

A vehicle driver is provided with a display interface a smartphone, tablet, PC, or any telematics or in-vehicle device installed in the vehicle. The display interface presents a real-time target for the driver to follow to maximize fuel economy and safety, achieved by modulating the accelerator pedal appropriately.

Claims

1. A method to assist an operator to control a vehicle in a fuel-efficient manner, the vehicle including a throttle, comprising:

providing to the operator a display interface identifying two or more target zones, and a display pointer, the target zones defined by a baseline that represents a set of zero acceleration fuel rate versus vehicle speed data points;

receiving data generated during operation of the vehicle and, in response, to generate, continuously, values representing a current fuel rate;

converting the values to control signals that drive the display pointer with respect to the two or more target zones to provide the operator visual feedback of current fuel rate against the baseline; and

in response to providing the operator visual feedback, receiving information indicating a change in an amount of throttle applied by the operator, wherein the change in the amount of throttle adjusts fuel consumption by the vehicle.

2. The method as described in claim 1 wherein the data generated during operation of the vehicle is one of:

vehicle speed, engine load, engine speed, fuel rate, transmission gear value, and mass air flow.

3. The method as described in claim 1 wherein the baseline is adjusted based on one of:

time of day, temperature, location, a location difficulty, a percent grade of a road.

4. The method as described in claim 1 wherein the baseline is adjusted based on one of:

driver history, a driver identifier, vehicle history, target location, driver handicap, and a vehicle identifier.

5. The method as described in claim 1 wherein the two or more target zones comprise a first green zone, a second yellow zone, and a third red zone.

6. The method as described in claim 1 wherein the display interface further includes a meter.

7. The method as described in claim 6 further including incrementing a value displayed in the meter when the pointer is maintained in a target zone below the baseline.

8. The method as described claim 7 further including inhibiting incrementing the value displayed in the meter for a given time period when the point moves into a target zone above the baseline.

9. A method to assist an operator to control a vehicle in a fuel-efficient manner, the vehicle having a throttle, comprising:

for a given vehicle class of which the vehicle is a member, generating a baseline that represents a set of zero acceleration fuel rate versus vehicle speed data points;

during operation of the vehicle, generating a display interface that provides visual feedback to the operator with respect to the operator'"'"'s ability to maintain an indicator in a given position with respect to the baseline; and

in response to providing the operator visual feedback, receiving information indicating a change in an amount of throttle applied by the operator, wherein the change in the amount of throttle adjusts fuel consumption by the vehicle.

10. The method as described in claim 9 further including adjusting the baseline.

11. The method as described in claim 10 wherein the baseline is adjusted using data that originates externally to the vehicle and represents one or more local environmental conditions associated with a current operation of the vehicle.

12. The method as described in claim 10 wherein the baseline is adjusted using data that is historical and that associates one or more of the following attributes:

a particular driver, a particular job or route.
