Title:
TAMPER SECURITY SYSTEMS AND METHODS FOR VEHICLES
Document Type and Number:
WIPO Patent Application WO/2019/189265
Kind Code:
A1
Abstract:
A passive entry / passive start (PEPS) system includes a communication gateway (29) to transmit a ping signal based on at least one of a predetermined period and a predetermined transmission power level. The PEPS system includes at least one sensor to receive the ping signal and measure a physical characteristic of the ping signal. The PEPS system includes a central module (20) to receive the measured physical characteristic of the ping signal, determine a lower threshold and an upper threshold associated with the at least one sensor, and compare the measured physical characteristic of the ping signal to the lower threshold and the upper threshold. In response to determining that the measured physical characteristic is less than the lower threshold and greater than the upper threshold, the central module notifies a portable device (10) that the at least one sensor has been tampered with.
