    摘要: An authentication system includes a first controller that performs wireless communication with a mobile terminal and a first authentication unit that executes authentication of the mobile terminal including ID authentication and code authentication through the wireless communication performed between the first controller and the mobile terminal. The first authentication unit executes the code authentication by determining whether a terminal-side calculation result obtained by the mobile terminal matches a controller-side calculation result obtained by the first controller. The authentication system further includes a second controller that communicates with the mobile terminal and a second authentication unit that applies encryption communication using a portion of the terminal-side calculation result and a portion of the controller-side calculation result to communication performed between the second controller and the mobile terminal and authenticates the encryption communication.

    摘要: A system that prevents accomplishment of unauthorized communication between a terminal and a communication peer is provided. The system includes a measurement unit and a process execution unit. The measurement unit is arranged on at least one of the terminal or the communication peer to obtain a measured value corresponding to a distance between the terminal and the communication peer. The process execution unit determines whether the measured value is appropriate and controls actuation for authentication of the terminal through wireless communication performed between the terminal and the communication peer based on the determination result. The measurement unit executes a process for obtaining the measured value in a time period during which the communication for the authentication is not performed.

    摘要: Each tire pressure detector detects a characteristic point in a detection signal of an acceleration sensor indicating that the tire pressure detector is located at a certain rotation position. When detecting the characteristic point, the tire pressure detector transmits a notification signal including the detector ID. Whenever a receiver receives a notification signal, the receiver acquires an axle rotation amount of a representative wheel and stores the axle rotation amount in a memory in association with the detector ID in the notification signal. After acquiring axle rotation amounts associated with the detector IDs of all of the tire pressure detectors, the receiver determines mounting positions of tires from the angle each tire pressure detector rotated and the angle each axle rotated between a first determination timing and a second determination timing.

    摘要: A tire position determination system includes a tire pressure detector coupled to a tire. A tire position determination unit locates the tire pressure detector and determines a mounting position of the tire. A gravitational component force detection unit generates gravitational force information of the tire pressure detector. A characteristic value acquisition unit acquires the angle of the tire pressure detector from the gravitational force information. The characteristic value acquisition unit acquires a first characteristic value of the tire pressure detector when a drive source of the vehicle is stopped and a second characteristic value of the tire pressure detector when the drive source is started. A characteristic value comparator compares the first and characteristic values. An operation control unit determines whether the mounting position of the tire has been changed based on the comparison and controls the tire pressure monitoring unit accordingly.

    摘要: A tire position determination system includes a tire pressure detector attached to each tire to generate a tire pressure signal. An acceleration detector generates gravitational information for each tire pressure detector. A receiver arranged in a vehicle body receives the tire pressure signal from each tire pressure detector. An axle rotation amount detector detects an axle rotation amount of an axle corresponding to each tire and generates pulses indicative of the detected axle rotation amount. An automatic locator determines the position of each tire based on the gravitational force and the pulses. A pulse combination determination unit determines whether or not a combination of the pulses from the axle rotation amount detectors is appropriate. A pulse acquisition timing setting unit sets an acquisition timing of the pulse signal for the automatic locator based on the determination of the pulse combination determination unit.

    摘要: An unauthorized communication establishment prevention system includes a measurement unit arranged in at least one of a terminal and a communication peer. The measurement unit implements an unauthorized communication detection function and obtains a measurement value corresponding to a distance between the terminal and the communication peer. The system further includes a process execution unit that controls initiation, based on a determination result of whether the measurement value is appropriate, of an authentication performed through wireless communication established between the terminal and the communication peer even when the terminal is not operated. The system further includes a monitoring unit that monitors a battery level of the terminal and a suspension unit that suspends the unauthorized communication detection function when the battery level of the terminal is less than a specified amount that is not a battery depletion level.
