Lexus introduced a multi-mode lane keeping assist system on the LS 460, which utilizes stereo cameras and more sophisticated object- and pattern-recognition processors. This system can issue an audiovisual warning and also (using the electric power steering or EPS) steer the vehicle to hold its lane.
If the driver is not paying attention to the road ahead and a dangerous situation is detected, the system will warn the driver by flashing lights, warning sounds. If no action is taken, the vehicle will apply the brakes (a warning alarm will sound followed by a brief automatic application of the braking system).
The warning is displayed to the driver in line with 49 CFR Part 571 Federal Motor Vehicle Safety Standards (FMVSS). The minimum requirement for the warning is in the form of a simple lit symbol on the dashboard, and this is often augmented by the display of a graphic of the car showing the wheel position to which the warning light corresponds.
The warning is followed by light braking to get the driver's attention. The third phase initiates autonomous partial braking at a rate of 3 m/s 2 (9.8 ft/s 2 ). The fourth phase increases braking to 5 m/s 2 (16.4 ft/s 2 ) followed by automatic full braking power, roughly half a second before projected impact.
Typically, bulbs of 21 to 27 watts producing 280 to 570 lumens (22 to 45 mean spherical candlepower) are used for stop, turn, reversing and rear fog lights, while bulbs of 4 to 10 W, producing 40 to 130 lm (3 to 10 mscp) are used for tail lights, parking lights, side marker lights and side turn signal repeaters.
