Abstract
Breakaway detection and alerting is described for a towed vehicle. In one example, a system includes a wired breakaway detector having a detector to generate an electric breakaway detection signal when a breakaway cable is not in a breakaway cable socket and an electrical cable to indicate the electric breakaway detection signal, and a wireless interface configured to be attached to the towed vehicle outside of the interior driver's area, to receive the electric breakaway detection signal from the breakaway detector and having a wireless transceiver to transmit a wireless breakaway alert signal in response to receiving the electric breakaway detection signal. A portable brake activation system receives the wireless breakaway alert signal from the wireless interface in the interior driver's area of the towed vehicle and activates the towed vehicle braking system through the attached brake pedal in response to the wireless breakaway alert signal.
