Abstract

Exemplary embodiments are provided of telematics devices and exemplary corresponding methods. In an exemplary embodiment, a telematics device generally includes a controller and a wireless communication module for transmitting data to a remote station. The controller is configured to periodically obtain the speed of a vehicle, determine when the speed of the vehicle has exceeded a first speed threshold, store the monitored speed as a max speed value, and compare each successive monitoring interval speed to a previous monitoring interval speed. When the successive monitoring interval speed is greater than the max speed value, the max speed value is updated. A speeding event occurs when each successive monitoring interval speed is above the first speed threshold for a speed duration, and/or when any successive monitoring interval speed exceeds a second speed threshold.

Claims22

Dependent claims

A telematics device for a vehicle, the device comprising:

a controller;
and
a wireless communication module coupled to the controller, the wireless communication module configured to transmit data from the controller to a remote station;
wherein the controller is configured to:
periodically obtain a speed of the vehicle according to a monitoring interval;
determine a first monitoring interval in which the speed of the vehicle has exceeded a first speed threshold and store the speed during the first monitoring interval as a max speed value;
compare each successive monitoring interval speed to a previous monitoring interval speed;
when the successive monitoring interval speed is greater than the max speed value, update the max speed value with the successive monitoring interval speed;
when each successive monitoring interval speed is above the first speed threshold for a speed duration, determine that a first speeding event has occurred with a first speed value equal to the max speed value;
when any successive monitoring interval speed exceeds a second speed threshold, determine that a second speeding event has occurred with a second speed value equal to the second speed threshold;
count a number of times that a distance threshold has been exceeded by a distance traveled by the vehicle while the speed of the vehicle exceeds the first speed threshold;
when the count exceeds a limit threshold within a specified time period, determine that an aggressive driving event has occurred.
