Abstract: A combined vehicle passive entry/passive start (PEPS) and mobile electronic device wireless charging system. The system includes a vehicle transmitter configured to transmit a signal in accordance with a wireless charging protocol. The signal is transmitted through a first wireless communications channel for receipt by a mobile electronic device. A vehicle receiver is configured to receive response data from the mobile electronic device through a second wireless communications channel. The response data is generated by the mobile electronic device in response to receipt of the signal transmitted by the vehicle transmitter. A vehicle processor module is configured to at least one of unlock doors of the vehicle and start the vehicle in response to receipt of the response data by the vehicle receiver.

Abstract: 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.

Abstract: Systems and methods are provided and include a control module that establishes a secure wireless communication connection with a portable device. A sensor receives connection information about the secure wireless communication connection, eavesdrops on the wireless secure communication connection based on the connection information, measures signal information of a communication signal sent from the portable device to the control module during the secure wireless communication connection, compares the measured signal information with wakeup criteria information, and reports the measured signal information to the control module in response to the measured signal information satisfying the wakeup criteria. The control module receives the measured signal information from the sensor and determines a location of the portable device based on the measured signal information. The measured signal information includes at least one of received signal strength indicator information, angle of arrival information, and time difference of arrival information.

Abstract: 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. The communication connection has a connection event during which information is exchanged between the communication gateway and the portable device. The communication gateway instructs sensors to perform two-way ranging using impulse radio (IR) ultra-wide band (UWB) communication with the portable device based on the information exchanged during the connection event. A localization module determines a location of the portable device based on the two-way ranging performed by the plurality of sensors. A PEPS system receives the location of the portable device from the localization module and performs a vehicle function, including unlocking a door of the vehicle, unlocking a trunk of the vehicle, or allowing the vehicle to be started, based on the location of the portable device.

Abstract: A sensor is configured to receive connection information from a portable device via a communication gateway in a vehicle and to communicate with a portable device using impulse radio (IR) ultra-wide band (UWB) communication based on the connection information. A location of the portable device is determined based on ranging using IR UWB communication.

Abstract: A portable device is configured to establish a Bluetooth low energy (BLE) communication connection with a vehicle and to communicate with at least one sensor in the vehicle using impulse radio (IR) ultra-wide band (UWB) communication after establishment of the BLE communication connection with the vehicle is completed. A location of the portable device is determined by the vehicle based on ranging using IR UWB communication performed by the at least one sensor.

Abstract: Systems and methods for vehicle passive entry/passive start (PEPS) are provided. A communication gateway in a vehicle establishes a Bluetooth low energy (BLE) or an impulse radio ultra-wide band (IR UWB) communication connection with a portable device that includes a wireless charging apparatus. A low-frequency transmitter transmits a ping request to the wireless charging apparatus. The portable device transmits a response to the ping request over the communication connection to the communication gateway. The communication gateway authenticates the portable device based on information included in the received response. A passive entry/passive start (PEPS) system performs a vehicle function in response to the portable device being authenticated, including unlocking a door of the vehicle, unlocking a trunk of the vehicle, allowing a wireless charging station of the vehicle to charge the portable device, or allowing the vehicle to be started.

Abstract: A magnetic repulsion system including a front electromagnet at a front, and a rear electromagnet at a rear, of a primary vehicle. A communication module is configured to determine whether a secondary vehicle directly adjacent to the primary vehicle is equipped with a secondary magnetic repulsion system. A sensor module of the primary vehicle is configured to identify when a collision between the primary vehicle and the secondary vehicle directly adjacent to the primary vehicle is imminent. A control module of the primary vehicle is configured to activate the front or rear electromagnet of the primary vehicle that is opposite to the secondary vehicle when both the sensor module identifies that a collision between the primary vehicle and the secondary vehicle directly adjacent to the primary vehicle is imminent, and the communication module receives notification that the secondary vehicle is equipped with the secondary magnetic repulsion system.

Abstract: An overcurrent protection circuit includes switches, resistors, and a voltage divider. A first switch includes a first control terminal and switches current to a load. The first resistor is connected in series with the first switch. The second resistor is connected in series with a second control terminal of the second switch and an output terminal of the overcurrent protection circuit. The voltage divider is connected in series with the second switch and has a center terminal connected to the first control terminal. A DC source voltage is across the second switch and the voltage divider. A latching circuit is provided by the switches, the voltage divider, the first resistor and the load. The second switch discharges the first switch to limit current to the output terminal in response to a voltage drop across the first resistor indicating current supplied to the output terminal has exceeded a threshold.
