Systems and methods for vehicle passive entry/passive start (PEPS) are provided. A communication gateway establishes a Bluetooth low energy communication connection with a portable device. A localization module determines a portable device location based on two-way ranging using impulse radio ultra-side band. The PEPS system performs vehicle functions, such as unlocking a door or trunk, allowing the vehicle to be started, or activating wireless charging, based on the portable device location. Another system includes at least one low frequency (LF) antenna configured to transmit a wireless charging ping signal within a predetermined range to a portable device configured for wireless charging. A communication gateway authenticates the portable device based on a response to the ping signal by the portable device. A PEPS performs vehicle functions, such as unlocking a door or trunk, or allowing the vehicle to be started, in response to authenticating the portable device.
