Onboard vehicle control system for use approaching traffic lights, detects traffic light phase, distance to lights, distance to any vehicle in front, etc., and plans an optimum approach behavior according to desired criteria

摘要

The system comprises a traffic phase reporting device (5) in the traffic lights themselves that transmits a signal to a receiver (7) in the vehicle. The vehicle also has a traffic lights distance detector (8), a vehicle distance detector (9) for determining the distance to a vehicle in front and a vehicle controller (11) that uses the information from the various sensors to optimize vehicle behavior on approach to the lights.
