    摘要： A key unit authenticates a portable terminal based on information acquired from the portable terminal and controls locking and unlocking of a target by transmitting a signal to a locking and unlocking device. The key unit includes: a first communication unit configured to receive a request signal transmitted in a first frequency band from the locking and unlocking device; a controller configured to authenticate the portable terminal and process signals transmitted to and received from the locking and unlocking device; a second communication unit configured to perform short-range wireless communication with the portable terminal in a second frequency band; and a substrate on which the first communication unit, the controller, and the second communication unit are mounted. The first communication unit and the second communication unit are mounted at positions facing each other across the controller, on the substrate.

    摘要： An onboard device includes a storage unit configured to store a control program for controlling the onboard device and a communication unit configured to perform data communication with a mobile terminal. The communication unit performs data communication of a rewriting program with the mobile terminal when the communication unit has received a rewriting notification signal indicating rewriting of the control program stored from the mobile terminal and the vehicle is in a chargeable state in which the battery is able to be charged by the power generator. The communication unit does not perform data communication of the rewriting program with the mobile terminal when the vehicle is not in the chargeable state.

    摘要： A key unit that locks and unlocks a target by transmitting a signal to a locking and unlocking device, includes: a substrate on which a power supply circuit and a reception circuit that receives a request signal transmitted in a first frequency band from the locking and unlocking device via a reception antenna are mounted; and a housing configured to accommodate the substrate. Among parts associated with the power supply circuit, a part having the highest height from a substrate surface is mounted on a first surface of the substrate. The reception antenna is mounted on a second surface. When the substrate is accommodated in the housing, a distance from a substrate surface of the second surface to an inner surface of the housing is shorter than a distance from the substrate surface of the first surface to the inner surface of the housing.

    摘要： An onboard device includes a storage unit configured to store a control program for controlling the onboard device and a communication unit configured to perform data communication with a mobile terminal. The communication unit performs data communication of a rewriting program with the mobile terminal when the communication unit has received a rewriting notification signal indicating rewriting of the control program stored from the mobile terminal and the vehicle is in a chargeable state in which the battery is able to be charged by the power generator. The communication unit does not perform data communication of the rewriting program with the mobile terminal when the vehicle is not in the chargeable state.
