Abstract:
1. A vehicle telematics system for wirelessly broadcasting a slip condition datagram, the system comprising: a slip detection circuit to detect a slipping condition between a wheel of a vehicle and a road surface; a first computer processor in communication with the slip detection circuit, the computer processor configured to (1) assemble a slip datagram indicating that a slipping condition has been detected at the vehicle and (2) cause the slip datagram to be wirelessly broadcast to make a notice available to one or more other vehicles in a particular vicinity that a slip condition is present; a transceiver in communication with the computer processor configured to wirelessly broadcast the slip datagram output by the computer processor; and a cellular telephone wirelessly paired with the transceiver, the cellular telephone configured to (1) wirelessly receive the slip datagram transmitted by the transceiver, and (2) transmit the slip datagram to a slip datagram processing center located remotely from the broadcasting vehicle, comprising a second computer processor and a memory device, and wherein the second computer processor is configured to record at least a portion of the slip datagram, to broadcast a datagram to one or more receiving vehicles including traction information, wherein one or more of the receiving vehicles includes a traction control system, and wherein the traction control system is configured to limit the torque or braking pressure applied to a wheel based on the traction information provided in the slip datagram(s), wherein the torque or brake pressure limit is determined based on a coefficient of friction provided in the slip datagram(s).
