摘要： 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.

摘要： 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. According to whether the vehicle-mounted receiver receives, from the portable device, a response signal to the second response request signal, the controller stops transmission of the second response request signal and then suppresses transmission of the first response request signal.

摘要： 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.

摘要： 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.

摘要： 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.
