Passive Proximity Detection

Atmel solution

Low Power Consumption: The average current consumption for a single proximity detection node should be less than 100uA to avoid excessive drain on the battery when the vehicle is not running

Fast Response Time: The sensor scan rate, the time between sensor reading should be less than 20ms. A fast scan rate means more sensor reading per second, which will result in earlier detection of driver's hand as it approaches the door handle sensor.

This will mitigate the delay introduced by communication processing and enable quickly unlock.

Simple, Low-cost interface:

Standard networking interfaces such as CAN or LIN requires excessive protocol/processing overhead and are too power hungry for this low power application. A simple, more streamlined approach is required, one that utilize a single-wire +12V power line data transfer protocol.

Robust Environmental Performance:

The proximity sensor must be able to withstand the harsh operating environment that the automobile exterior is exposed to. This means that the sensor must resist the effects of moisture, temperature and localized electromagnetic disturbance.
