New camera and multi-sensor package launched by TRW

TRW Automotive Holdings Corp has launched a new advanced camera and multi-sensor package for several automotive functions. The package is small and lightweight, yet includes the processing power needed to support a variety of functions. The camera/sensor unit is positioned in the region of the rearview mirror mount looking outward through the windshield. As well as an automatic on-off headlamp control, the technology can also determine – in low light conditions – if other traffic is in the vicinity and, if not, can automatically switch on the high beams for better vision at night or in tunnels.

In addition, the package also features a rain sensor that focuses on the windshield glass surface and uses an optical sensor that measures reflected light. The light reflection changes as moisture in the form of rain or snow falls on the windshield and the system will automatically engage the windshield wipers and can vary the speed of the wiper motor depending on the amount of moisture detected. Another feature that can be included in the package is a humidity sensor that detects the amount of humidity in the vehicle interior and can activate the blower motor within the HVAC system to keep the windshield defogged.

“Giving a vehicle the capability of seeing the road, the environment and the lighting conditions under which a driver is operating can be incredibly powerful,” suggest Martin Thoone, vice-president, TRW Electronics Engineering. “A multitude of things are possible from a package about the size of a deck of playing cards that can include a camera, rain sensor and the processor. Beyond the many safety benefits are the comfort and convenience possibilities, such as automatic headlights and windshield wiping without the driver needing to do anything. With so many distractions commanding the attention of today’s driver, the automation of various functions can help to keep greater attention on the road ahead, and functions such as keeping the outer windshield free of moisture, the inner glass defogged and the headlights on at the optimal setting when low light conditions demand them, all benefit giving the driver a clearer vision of their surroundings.”
