Patent number: 11945402Abstract: A method/system of detecting if a relay is present in a vehicle PEPS system, including transmitting from antenna(s) of a vehicle, a first/second LF signals and determining a minimum time-gap between the signal transmissions so that the time-gap exceeds the channel-coherence-time of a high-frequency wireless-relay. A maximum time between the signals is determined by a timing requirement of the PEPS system and the maximum allowable change in a key-fob position. A time gap between the minimum/maximum times is determined. Depending on the time-gap, the system timing requirement is increased to provide a predetermined-time. At the predetermined-time, separately transmitting between the first/second LF signals, which have a known signal ratio, from a vehicle antenna to a key-fob as part of an LF challenge; measuring, at the key-fob, the signal-levels of the first/second LF signals; and determining if the ratio of the first/second LF signals are within a predefined range.Type: GrantFiled: September 23, 2020Date of Patent: April 2, 2024Assignee: ROBERT BOSCH (AUSTRALIA) PTY LTDInventor: Matthew S.

Patent number: 10819449Abstract: A method and system for near field localization includes providing at least one transmitting antenna and at least a first and second set of receiving antennas, the first and second set of receiving antennas provided at a known distance R12 to each other and at a first radial distance r1 and second radial distance r2 from the transmitting antenna respectively. The first radial distance r1 is determined relative to the magnetic field strength proportional to a RSSI measurement and a first subtended angle ?1. The second radial distance r2 is determined relative to the magnetic field strength proportional to a RSSI measurement and a second subtended angle ?2.Type: GrantFiled: May 23, 2018Date of Patent: October 27, 2020Assignee: ROBERT BOSCH (AUSTRALIA) PTY LTDInventors: Daniel Kornek, Andrew Thompson

Patent number: 9694787Abstract: A method for determining the location of a remote transceiver in relation to a vehicle, the method including the steps of: transmitting at least two measuring signals to the remote transceiver, each of the measuring signals being transmitted from a different one of a plurality of n antennae positioned relative to the vehicle, where n denotes an integer?2; receiving an acknowledgement signal from the remote transmitter in response to each measuring signal, each acknowledgement signal including a received signal strength indication (RSSI) for a respective received measuring signal, the values of the received RSSIs together defining a data point in an RSSI domain; and determining a difference between the received value of a first RSSI and a defined threshold value for that first RSSI, wherein the sign of the difference indicates whether the remote transmitter is inside or outside a defined region i of or near the vehicle.Type: GrantFiled: March 21, 2014Date of Patent: July 4, 2017Assignee: ROBERT BOSCH (AUSTRALIA) PTY LTDInventors: Daniel Kornek, Ewen James Christopher
