GAWR exceed warning system for a vehicle
First Claim
1. A warning system for a vehicle having a front axle, a rear axle and an air suspension system, comprising:
- an indicator;
an event data recorder; and
a controller operatively associated with the air suspension system, the event data recorder and the indicator, the controller configured to;
determine a load on the front axle and the rear axle when the vehicle is in a static condition;
compare the determined load on the front and rear axles to a predetermined load threshold for each of the front and rear axles;
provide a warning signal to the indicator indicative of at least one of the determined loads exceeding the corresponding predetermined load threshold upon the controller determining one of the determined loads exceeds the corresponding predetermined load threshold;
lower a ride height of the vehicle when at least one of the determined loads exceeds the corresponding predetermined load threshold; and
communicate data indicative of at least one of the determined loads exceeding the corresponding predetermined threshold to the event data recorder;
wherein the indicator includes at least one of an audio visual system associated with an interior of the vehicle, a dedicated warning display system associated with the interior of the vehicle, and a warning system associated with an exterior of the vehicle.

Abstract
A warning system for a vehicle having an air suspension system can include an indicator, an event data recorder, and a controller. The controller can be configured to determine a load on a front axle and a rear axle when the vehicle is in a static condition and compare the determined load on the front and rear axles to a predetermined load threshold for each of the front and rear axles. A warning signal can be provided to the indicator indicative of at least one of the determined loads exceeding the corresponding predetermined load threshold upon the controller determining one of the determined loads exceeds the corresponding predetermined load threshold. Data indicative of at least one of the determined loads exceeding the corresponding predetermined threshold can be communicated to the event data recorder.

10. A warning system for a vehicle including a front axle, a rear axle and an air suspension system, comprising:
-
an indicator; an electronic stability control system including a longitudinal accelerometer; an event data recorder configured to record certain vehicle conditions and data associated therewith; and a controller operatively associated with the indicator, air suspension system, electronic stability control system and event data recorder, the controller configured to; determine a load on the front axle and the rear axle when the vehicle is in a static condition based on data from the air suspension system; determine if the vehicle is on a grade; determine a grade compensated load on the front axle and the rear axle when the vehicle is on a grade and is in a static condition; compare the determined load on the front and rear axles to a predetermined load threshold for each of the front and rear axles when the vehicle is not on a grade; compare the grade compensated load on the front and rear axles to the predetermined load threshold for each of the front and rear axles when the vehicle is on a grade; provide a warning signal to the indicator indicative of at least one of the determined loads or at least one of the grade compensated loads exceeding the corresponding predetermined load threshold upon the controller determining at least one of the determined loads or at least one of the grade compensated loads exceeds the corresponding predetermined load threshold; and communicate data indicative of at least one of the determined loads or at least one of the grade compensated loads exceeding the corresponding predetermined threshold to the event data recorder for a duration that the at least one of the determined loads or at least one of the grade compensated loads exceeds the corresponding predetermined threshold. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A warning system for a vehicle having a front axle, a rear axle and an air suspension system, comprising:
-
an indicator; an event data recorder; and a controller operatively associated with the air suspension system, the event data recorder and the indicator, the controller configured to; determine a load on the front axle and the rear axle when the vehicle is in a static condition; compare the determined load on the front and rear axles to a predetermined load threshold for each of the front and rear axles; provide a warning signal to the indicator indicative of at least one of the determined loads exceeding the corresponding predetermined load threshold upon the controller determining one of the determined loads exceeds the corresponding predetermined load threshold; lower a ride height of the vehicle when at least one of the determined loads exceeds the corresponding predetermined load threshold; and communicate data indicative of at least one of the determined loads exceeding the corresponding predetermined threshold to the event data recorder; wherein the indicator includes a first indicator associated with an instrument panel of the vehicle and configured to issue a visible and audible warning, and a second indicator associated with an exterior of the vehicle adjacent a cargo bed of the vehicle and configured to issue a visible and audible warning. - View Dependent Claims (18)

19. A warning system for a vehicle having a front axle, a rear axle and an air suspension system, comprising:
-
an indicator; an event data recorder; and a controller operatively associated with the air suspension system, the event data recorder and the indicator, the controller configured to; determine a load on the front axle and the rear axle when the vehicle is in a static condition; compare the determined load on the front and rear axles to a predetermined load threshold for each of the front and rear axles; provide a warning signal to the indicator indicative of at least one of the determined loads exceeding the corresponding predetermined load threshold upon the controller determining one of the determined loads exceeds the corresponding predetermined load threshold; lower a ride height of the vehicle when at least one of the determined loads exceeds the corresponding predetermined load threshold; and communicate data indicative of at least one of the determined loads exceeding the corresponding predetermined threshold to the event data recorder; further comprising an electronic stability control system having at least a longitudinal accelerometer, the electronic stability control system operatively coupled to the controller, the controller in cooperation with the longitudinal accelerometer configured to determine an increased resultant force being exerted on one of the front and rear axles based on the vehicle being on a grade and account for this increased resultant force in determining if at least one of the determined loads exceeds the corresponding predetermined threshold. - View Dependent Claims (20)
