Abstract:
A method for vehicle data management according to embodiments of the present invention includes receiving an accelerometer signal from an accelerometer mounted in a vehicle, determining an accelerometer specific force based on the accelerometer signal, receiving a speed signal from a speed sensor or GPS or other source on the vehicle, wherein the speed signal indicates a speed of the vehicle, determining an instantaneous acceleration of the vehicle by calculating a rate of change of the speed based on the speed signal, selecting a current observed acceleration as a lower value of the accelerometer specific force and the instantaneous acceleration, capturing video footage with a camera mounted on the vehicle, and flagging the video footage corresponding to a time when the current observed acceleration exceeds a preset safe force value.
Abstract:
A system for vehicle data management according to embodiments of the present invention includes a specific force sensing device located on an emergency vehicle, a speed sensing device located on the emergency vehicle, a condition indicator located on the emergency vehicle configured to indicate information about presence or absence of a condition; and a vehicle data management device communicably coupled to the specific force sensing device, the speed sensing device, and the condition indicator. The vehicle data management device can be configured to establish a vehicle record, determine whether the condition is present or absent based on the information from the condition indicator, adjust a speed limit and a specific force limit based on the determination, and create a flag when one or both of the speed is higher than the speed limit and the specific force is higher than the specific force limit.
