LIVONIA, Mich., Nov. 17, 2011 /PRNewswire/ -- TRW Automotive Holdings Corp. (NYSE: TRW), the global leader in automotive safety systems, is expanding its vehicle access product portfolio to include advanced Passive Entry systems and has secured initial business awards in North America.
Passive Entry (PE) systems take the benefits of traditional Remote Keyless Entry (RKE) system a step further and enable the car doors (and the trunk if desired) to be automatically unlocked when a person carrying the key-fob comes within close proximity of the vehicle, and lock automatically when the key fob holder moves away from the vehicle without any need to press the key-fob buttons – the fob can remain in a purse, handbag or jacket pocket. This maintains vehicle security while allowing a driver or passenger easy hands-free entry into the vehicle.
Beyond the convenience advantages, TRW has the electronics expertise to integrate the RKE / Passive Entry and Tire Pressure Monitoring System receiver functions into a single electronic control unit (ECU) to make these systems more affordable."There are many potential advantages to Passive Entry systems," said Martin Thoone, vice president, Global Electronics Engineering. "Once the fob has been recognized by the Passive Entry system a range of functions are available, such as lighting the interior at night time; starting the engine by simply pressing a start/stop button in the vehicle interior, and alerting the driver if they have left the key fob in the car with the engine running." "In addition, TRW is using its considerable experience in RF products including RKE and Tire Pressure Monitoring to find ways to integrate the electronics, cutting down on the number of components and simplifying the system installation while offering greater opportunities to deliver information and personalize the driving experience. For example the key fobs could store vehicle data including mileage, tire pressure data, vehicle service information and navigation map information, as well as personal settings for interior features such as seat and mirror positions and radio and air conditioning settings."
