Suzuki Swift V CAN controller – turn on a front camera only if speed below 15km

Speed-Gated Parking Sensors on a Suzuki Swift V — Reading Speed Straight off the CAN Bus

An ESP32-C3 quietly listens to the car’s CAN bus, decodes vehicle speed from the
ABS wheel-speed broadcast, and switches a relay that enables the aftermarket
parking controller — which in turn drives the front sensors and the
camera — only below 15 km/h. No splicing into the speedometer,
no aftermarket speed pulse — just the bus the car already talks on.
