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.
