Abstract

A system for a vehicle comprises a load sensor configured to sense a load on the vehicle. The vehicle further includes a load indicator where the load indicator is disposed proximate the vehicle such that the load indicator generates an output in response to the load sensed by the load sensor.

Claims

1. A load indicator system for a vehicle comprising:

a load sensor disposed in a vehicle bed;

at least one load indicator disposed outside of the vehicle; and

a controller in communication with the load sensor and the at least one load indicator wherein the controller is configured to;

receive a detection of an operator proximate the vehicle; and

provide a load indication in response to a load sensed by the load sensor and the detection of the operator proximate the vehicle.

2. The load indicator system for a vehicle of claim 1, wherein the load indication comprises activation of a first load indicator at a first location.

3. The load indicator system for a vehicle of claim 2, wherein the load indication further comprises activation of a second load indicator at a second location.

4. The load indicator system for a vehicle of claim 2, wherein the first location comprises a location above a rear windshield.

5. The load indicator system for a vehicle of claim 3, wherein the second location comprises a location proximate a rear taillight.

6. The load indicator system for a vehicle of claim 4, wherein the location above the rear windshield comprises an elongated light configured to display a percentage of an allowable load.

7. The load indicator system for a vehicle of claim 5, wherein the location proximate the rear taillight comprises a backup light configured to display a percentage of allowable load.

8. The load indicator system for a vehicle of claim 3, wherein a vehicle bed separates the first location and the second location.

9. The load indicator system for a vehicle of claim 1, wherein the load sensed by the load sensor comprises a first load amount within a first predetermined load range or a second load amount within a second predetermined load range.

10. The load indicator system for a vehicle of claim 9, wherein the controller activates a first load indicator in response to a detection of the first load amount and wherein the controller activates a second load indicator in response to a detection of the second load amount.

11. The load indicator system for a vehicle of claim 10, wherein the controller activates the second load indicator in response to the detection of the first load amount.

12. A vehicle load indicator system comprising:

a load sensor disposed beneath a vehicle bed;

a load indicator outside a vehicle; and

a controller in communication with the load sensor and the load indicator wherein the controller is configured to;

receive a detection of an operator proximate the vehicle; and

activate the load indicator to generate an output in response to a detection of a load condition and the detection of the operator proximate the vehicle.

13. The vehicle load indicator system of claim 12, wherein the load indicator comprises a first load indicator that displays a first output in response to a detection of a first load condition and a second load indicator that displays a second output in response to a detection of a second load condition.

14. The vehicle load indicator system of claim 13, wherein the first load condition comprises a detection of a first payload amount and the second load condition comprises a detection of a second payload amount.

15. The vehicle load indicator system of claim 14, wherein the first payload amount is less than the second payload amount.

16. The vehicle load indicator system of claim 15, wherein the first load indicator comprises an elongated light proximate a vehicle cabin and wherein the second load indicator comprises a light proximate a rear taillight.

17. The vehicle load indicator system of claim 16, wherein the elongated light proximate a vehicle cabin comprises a CHMSL.

18. A method for indicating a vehicle load comprising the steps of:

detecting an operator within a proximity of a vehicle;

detecting a first load condition;

detecting a second load condition;

comparing the first and second load conditions to a payload weight change history in response to the detection of the operator; and

activating a load indicator to display the first and second load conditions.

19. The method for indicating a vehicle load of claim 18, wherein activating a load indicator to display the first and second load conditions further comprises the steps of:

activating a first load indicator to display the first load condition; and

activating a second load indicator to display the second load condition.

20. The method for indicating a vehicle load of claim 19, wherein detecting the first load condition further comprises the step of:

detecting a first load within a first load range between a minimum load and an intermediate load; and

wherein detecting the second load condition further comprises the step of;

detecting a second load that comprises an intermediate load or a load within a second load range between the intermediate load and a maximum load.
