Initial movement indicator system and method for a wheeled ground vehicle
First Claim
Patent Images
1. A method for indicating initial movement of a wheeled ground vehicle from a stop or low-speed condition, comprising the steps of:
- assessing a rate parameter that is proportional to a rate of vehicle movement along the ground;
determining whether the vehicle is accelerating; and
if and only if the rate parameter is greater than zero but less than a predetermined value and the vehicle is accelerating, activating a warning system so as to provide an indication of initial movement of the vehicle.

Abstract
An initial movement indicator for a vehicle comprises at least one warning light, and a controller structured and arranged to receive a signal indicative of vehicle movement along the ground and to process said signal to determine a rate parameter that is proportional to a rate of said vehicle movement and to determine whether the vehicle is accelerating, the controller being structured and arranged to cause the at least one warning light to be illuminated if and only if the rate parameter is greater than zero but less than a predetermined value and the vehicle is accelerating.

22. An initial movement indicator for a wheeled ground vehicle, comprising:
-
at least one warning light; means for determining a rate parameter proportional to a rate of vehicle movement along the ground; means for determining whether the vehicle is accelerating; and means for illuminating the at least one warning light if and only if the rate parameter is greater than zero but less than a predetermined value and the vehicle is accelerating.

23. A wheeled ground vehicle, comprising:
-
a body mounted on a set of wheels, the body having a front end, a rear end, a left side, and a right side; at least one warning light mounted on the body so as to be visible to persons outside the vehicle; a sensor mounted in the vehicle and operable to create a signal indicative of vehicle movement along the ground and the rate of said vehicle movement; a controller connected to the sensor and to the at least one warning light, the controller being structured and arranged to process said signal from the sensor to determine a rate parameter that is proportional to the rate of vehicle movement along the ground and to determine whether the vehicle is accelerating, the controller being structured and arranged to cause the at least one warning light to be illuminated if and only if the rate parameter is greater than zero but less than a predetermined value and the vehicle is accelerating. - View Dependent Claims (24, 25, 26, 27)
