摘要： A positioning device performs positioning to measure a position of a vehicle. The positioning device receives a signal transmitted from a GNSS satellite. The positioning device perform a positioning calculation using the signal. The positioning device communicates with a positioning server. The positioning device selects, as a system for the positioning, one of a first positioning system and a second positioning system.

摘要： A positioning device measures a position of a vehicle by including a controller. The controller provides (i) a first positioning system to obtain a first positioning result having a first accuracy by performing positioning using a signal from a GNSS satellite and (ii) a second positioning system to obtain a second positioning result having a second accuracy higher than the first accuracy, by using acquired vehicle-related information, instead of or in addition to the first positioning result. The controller selects, as a selected positioning system to obtain a selected positioning result, either (i) the first positioning system or (ii) the second positioning system. In response to determining that the second accuracy of the second positioning result is lower than the first accuracy of the first positioning result, the controller is configured to switch the selected positioning system to select the first positioning system.

摘要： A communication apparatus is mounted on a vehicle together with a control apparatus configured to accept, from a device electrically connected to a connector on the vehicle, a communication request to request transmission of data and transmit a communication response including the data to the device. The communication apparatus includes a communication interface configured to sequentially transmit two or more communication requests to the control apparatus, and in a case in which a communication response corresponding to at least one of transmitted communication requests is received from the control apparatus, transmit data included in the received communication response to a server apparatus installed in a location different from the vehicle, and a controller configured to determine whether a device to be detected is electrically connected to the connector depending on whether the communication interface has received a communication response corresponding to each of the two or more communication requests.
