A terminal performs communication with an in-vehicle device to control a vehicle. The terminal includes a controller configured to switch and set a plurality of operation modes, and a vibration detection unit configured to detect vibration of the terminal. The operation modes include a first mode, a second mode different from the first mode, and a third mode where communication with the in-vehicle device is more restricted than in the first mode and the second mode. The controller is configured to, when the first mode is executed, in a case where vibration is not detected in the vibration detection unit for a predetermined time, switch the operation mode to the third mode, and when the second mode is executed, in a case where vibration is not detected in the vibration detection unit for a time longer than the predetermined time, switch the operation mode to the third mode.

A power supply control module includes a first sheet portion, a second sheet portion, a wireless communication unit, a switch unit and a controller. The controller configured to cause the switch unit to switch between a closed state and an opened state based on the result of communication performed by the wireless communication unit, the closed state being a state in which a first cell side electrode layer and a terminal side electrode layer are electrically connected to each other and the opened state being a state in which the first cell side electrode layer and the terminal side electrode layer are electrically disconnected from each other.

A fob for a passive entry passive start (PEPS) system includes a LF receiver, an UHF transmitter, an UWB transceiver, a primary battery to power the receiver and the transmitter, a rechargeable secondary battery to power the transceiver, and a controller. The controller may cause the primary battery to recharge the secondary battery when the secondary battery has a low charge. The controller may cause the transmitter to transmit an indication to a base station of the PEPS system that the primary battery has a low charge. This indication is to alert a user to replace the primary battery. The controller may cause the transmitter to transmit an indication that the secondary battery is dead when the secondary battery is detected to be dead. This indication is to alert the base station that PEPS communications of the fob will not involve the transceiver.

Embodiments of the present invention provide a kit comprising a device and a charger each having a curved design. The device comprises a housing, a receive coil and a rechargeable electrical power storage element. The charger for the device comprises a yoke and a transmit coil. The receive coil axis and the transmit coil axis are arranged such that the receive coil and the transmit coil form an inductive coupling. Advantageously, the device may therefore be charged by the charger without a direct wired connection between the device and a power supply, despite the device and charger having a curved design.

An antenna driving apparatus includes: a direct current power source supplying direct current power to a human detecting IC detecting contact to a human detecting area by a user, the power source outputting a power source voltage to a first connecting line connected to a power source terminal of the IC and outputting a reference potential to a second connecting line connected to a GND terminal of the IC; an antenna driving circuit driving an antenna transmitting a signal to a portable device, the antenna driving circuit outputting a first antenna drive signal to the first connecting line and outputting an antenna drive signal; and a control unit performing switching control of the power source voltage and the antenna drive signal to be output to the first and second connecting lines and switching control of the antenna driving circuit.

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.

A vehicle that is configured to: acquire information relating to a remaining charge of a battery of a terminal configured to act as a digital key employed in control of a vehicle; and perform a predetermined notification in response to both of a determination being made that the remaining charge of the battery of the terminal is a predetermined threshold or lower based on the acquired information, and the vehicle being in a preset vehicle state.

A passive entry system for an automotive vehicle that is configured to prevent relay attacks by analyzing magnet vectors and angles created by a plurality of antennas mounted on the vehicle is disclosed. A vehicle including a control unit configured to broadcast a wake-up signal to prompt a fob to power-up if the fob is in a low-power consumption mode and to transmit signals through a plurality of antennas coupled to the vehicle is provided, along with a fob configured to recognize the wake-up signal and to generate a response signal for the control unit in response to recognize the wake-up signal. The fob includes a controller that is programmed to receive signals transmitted from each of the plurality of antennas coupled to the vehicle, retrieve constant values from stored a memory, and calculate a magnetic integrity defining the relative position of each of the plurality of antennas. The controller allows access to the vehicle if magnetic integrity is found, and denies access to the vehicle if magnetic integrity is not found.

A lock system for access authorization in a motor vehicle, having a first device which has at least two states and is embodied as a control device, and having an associated second device which is embodied in the manner of an electronic key, an ID signal transmitter, a chip card or the like. The two devices have transmitters and/or receivers for electromagnetic signals. At least one of the signals transmitted between the second device and the first device is an encoded operating signal for authenticating the second device, with the result that after a positive evaluation of the transmitted operating signal when the second device is authorized it is possible to bring about a change in the state of the first device.
