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.
