A speed exceeded notification device is for a vehicle of a type including
a vehicle data communications bus extending throughout the vehicle, and
at least one vehicle device generating data related to vehicle speed on
the vehicle data communications bus. The speed exceeded notification
device may include a wireless communications device, and a controller to
be coupled to the vehicle data communications bus. The controller may be
for reading the data related to vehicle speed from the vehicle data
communications bus, and determining when a vehicle speed exceeds a speed
threshold for a first time period. The controller may also be for
determining when the vehicle speed exceeds the speed threshold for a
second time period less than the first time period and, in response
thereto, generating a local vehicle speed exceeded notification. Based
thereon, the controller may cooperate with the wireless communications
device to send a remote vehicle speed exceeded notification.
