A lane departure warning system (LDWS) has been developed. The system has functions to predict vehicle's departure from the lane with a CCD camera and warn the driver with visual and sound messages, plus steering wheel vibration. Moreover, the system generates an additional steering torque to urge the driver to take a corrective steering operation. It is needless to say that the core technology of this system is lane recognition. Because the system's main objective is to attain high practicality and high reliability, in other words, to reduce missed warnings and false warnings, various improvements have been required in the hardware and the software of the lane recognition system. As a result, LDWS has been proven to be highly practical and reliable through on-road evaluation.
