Lexus has introduced new safety technology that detects three-dimensional objects in the path of vehicles, dubbed Active Pedestrian Detection System* (APDS).

The system uses a combination of stereo cameras and infra-red technology to enhance night-time operation, and to detect and monitor objects that move across the path of the vehicle.

The system is designed to aid drivers in situations where visibility is low, or at times when drivers may become distracted from the road ahead.

Once the objects have been detected, the driver will be alerted to the pedestrian or object via a warning light and buzzer.

As the car gets closer to the obstacle, APDS can begin to gently apply the brakes on its own and decreases the steering ratio, amplifying the intensity and quickness of the steering response.

At the same time, the system automatically pre-tensions the front seatbelts and prepares the brake system to respond when activated by the driver, in anticipation of a possible impact.

Lexus Australia chief executive John Roca said that APDS was being studied for introduction into the Australian market.

"Lexus currently offers APDS in the United States and we are studying the introduction of the safety feature for the Australian market," said Mr Roca.

"Lexus has always been a technology leader and APDS just confirms our commitment to safety and technology.

"Over the past 20 years Lexus has forged its own technology path, introducing advanced technologies such as Hybrid Synergy Drive that have led the way for other manufacturers," said Mr Roca.
