Patent Images
1. An urgent deceleration indicating device to selectively activate a warning indicator comprising:
- (a) at least one warning indicator adapted to indicate a warning at least external to vehicle;
(b) a sensor system, having an output, responsive to acceleration in a primary direction of vehicle motion; and
(c) a controller responsive to the output of the sensor system, the controller correcting for gravitational effects such that at least one warning indicator is initiated when the acceleration exceeds at least one threshold value.

Abstract
A device and system for indicating rapid deceleration to warn the operator and/or others of an urgent deceleration condition is provided. The device includes one or more sensors that are responsive to acceleration in the primary direction of vehicle motion. The controller communicates with the one or more sensors, corrects for gravitational effects, and initiates at least one warning indicator when the sensed acceleration exceeds a threshold value and thereby indicates an urgent deceleration condition.
