TOKYO — Toyota Motor Corp. is adding two safety technologies to luxury sedans in Japan and likely will use them next on Lexus models.
One is a radar system that detects probable front and side collisions and warns the driver.
The other is a rear seat that prepares passengers for accidents by automatically adjusting to a more impact-cushioning position, Toyota said in a release.
Toyota said the features will appear soon on a Japan-market vehicle. The company did not name the vehicle, but local media say it may be a redesigned Crown Majesta, due late this month.
Toyota says the technology is being considered for Lexus.
The front and rear side pre-crash safety system uses millimeter-wave radar to detect objects moving into the vehicle's path. The system then warns the driver by sound or indicator.
If the crash is imminent, the pre-crash system activates countermaneuvers by braking, retracting motor-powered seat belts or deploying airbags.
When a rear-end collision is sensed, the seatbacks automatically rise from a reclining to upright position. They work in tandem with motor-powered seat belts that tighten before the crash and headrests that move forward to guard against whiplash.
In a related development, the redesigned 2010 Toyota Prius offers a radar system that adjusts vehicle speed, applies light braking if necessary and warns the driver to take evasive action if a crash is imminent.
The car is due in the United States in May.
