Abstract: A vehicle communication system includes a vehicle-mounted device and a portable device. In the vehicle communication system, a transmission unit transmits a first to third radio signals having intensities weaker in this order, a measurement unit measures an intensity of each of the radio signals, and a determination unit that determines whether an intensity difference between any two of the radio signals among the radio signals measured by the measurement unit is larger than a threshold value. Control of a target mounted on the vehicle is permitted if the intensity difference is larger than the threshold value.

Abstract: The present invention provides a polishing composition that can polish an object to be polished at a high polishing speed with fewer scratches (defects). The present invention relates to a polishing composition including silica and a dispersing medium, the polishing composition having, when analyzed by pulse NMR spectroscopy, a specific relaxation rate (R2sp) of from 1.60 to 4.20 as determined by the following Formula (1): R2sp=(R(silica))/(R(medium))?1 ??Formula (1): wherein R(silica) represents the reciprocal of the relaxation time of silica (unit:/millisecond), and R(medium) represents the reciprocal of the relaxation time of the dispersing medium (unit:/millisecond).

Abstract: An in-vehicle communication system includes: a plurality of local ECUs (vehicle control devices) connected to networks of buses, and configured to control an in-vehicle device; an OBDII port which is a communication port to an outside; and an illicit act detection sensor configured to detect an illicit act on a vehicle. Each local ECU includes a reprogramming receiver and a reprogramming controller. The reprogramming receiver receives a reprogramming request signal and reprogramming data from a reprogramming device connected to the OBDII port. Reprogramming for rewriting a software program of a target local ECU is executed according to the reprogramming request signal and the reprogramming data. When the illicit act detection sensor detects an illicit act, the reprogramming controller prohibits execution of reprogramming.

Abstract: A vehicle control apparatus includes: a vehicle-mounted transmitter which transmits a first response request signal; a vehicle-mounted receiver which receives, from a portable device, a response signal to the first response request signal; and a controller which allows an operation for welcoming a user carrying the portable device to a vehicle according to a reception state of the response signal. When intermittently transmitting the first response request signal at predetermined intervals via the vehicle-mounted transmitter, the controller determines whether condition set in advance is established. When the condition is established, the controller transmits a second response request signal different from the first response request signal. When the vehicle-mounted receiver receives a response signal which is transmitted from the portable device as a response to the second response request signal, the controller continues to transmit the second response request signal via the vehicle-mounted transmitter.

Abstract: A vehicle control system includes a vehicle control apparatus, a first portable device, and a second portable device. The first portable device transmits a first signal to the vehicle control apparatus based on the fact that a first operation by a user is performed on the second portable device. When the vehicle control apparatus receives the first signal from the first portable device, the vehicle control apparatus intermittently transmits a second signal to the first portable device. The first portable device measures a signal strength of the second signal received from the vehicle control apparatus, based on the fact that a second operation by the user is performed on the second portable device after the first operation. The vehicle control apparatus or the first portable device sets, as a distance threshold, a distance between the first portable device and the vehicle calculated from the measured signal strength.

Abstract: A vehicle control system includes a vehicle control apparatus mounted on a vehicle for controlling the vehicle, an electronic key carried by a user for performing communication with the vehicle control apparatus, and a portable device carried by the user for performing communication with the electronic key. When detecting user's getting in or out of the vehicle, the vehicle control apparatus determines a location of the electronic key based on communication with the electronic key. When the location of the electronic key is in the vehicle and the user has no intention of getting out of the vehicle, communication between the electronic key and the portable device is brought into a connected state. When the location of the electronic key is outside the vehicle and the user has no intention of getting in the vehicle, communication between the electronic key and the portable device is brought into a disconnected state.

Abstract: A vehicle control system includes a vehicle control apparatus that controls in-vehicle devices; and an electronic key and a portable device (smartphone) which are carried by a user. The portable device stores an in-vehicle device to be activated before the user gets in a vehicle among the in-vehicle devices, as personal setting data set by the user. When the portable device performs communication with the electronic key and establishes the communication, the portable device transmits the personal setting data to the electronic key. The electronic key transmits the personal setting data received from the portable device, to the vehicle control apparatus. Based on the personal setting data transmitted from the electronic key, the vehicle control apparatus activates the in-vehicle device set in the personal setting data, before the user gets in the vehicle.

Abstract: A vehicle control system includes a vehicle control apparatus mounted on a vehicle, a first portable device (electronic key) performing communication with the vehicle control apparatus, and a second portable device (smartphone) performing communication with the first portable device. The second portable device transmits, based on a predetermined operation by a user, a notification signal notifying about the operation to the first portable device. When the first portable device receives the notification signal from the second portable device, the first portable device transmits the notification signal with an identification code of the first portable device to the vehicle control apparatus. When the vehicle control apparatus detects a gesture of the user after receiving the notification signal and the identification code from the first portable device, the vehicle control apparatus extracts a feature of the gesture from a detection signal, and stores the feature to be associated with the identification code.
