A network device includes a memory, a display, a user interface, and a network communication module configured to receive vehicle data, driver information, and driver communications, at pre-determined times, from a plurality of portable wireless data transfer and display devices via a long-range wireless network. The network communication module is further configured to send and receive network communications with one or more of the portable wireless data transfer and display devices via the long-range wireless network. The network device is configured to present the vehicle data, the driver information, the driver communication, and the network communications from the plurality of portable wireless data transfer and display devices via the display. The user interface is configured to allow for selection of the drivers presented and is configured to accept user inputs of network communications via the user interface.

Provided are a vehicle data readout device and a vehicle data readout method with which it is possible to reduce power consumption in a state in which a vehicle has not been activated, even if the vehicle data readout device, which receives power from an in-vehicle power source, remains connected to the vehicle. Taking as a trigger a port voltage (Vp) of a readout communication line exceeding a voltage threshold (THv), a vehicle data readout device switches a change-over switch from off to on, to generate a pull-up state by means of a pull-up resistor, and initiates a read-out of operation parameter data (Dp) by a computer.

Example systems and methods for calculating driver reaction times are described. In one implementation, a method receives image data from a vehicle camera and identifies a light tree in the image data. A light activation sequence of the light tree is monitored based on the image data. The method detects movement of the vehicle and calculates a reaction time based on an elapsed time between activation of a last light in the light tree and movement of the vehicle.

A server divides a plurality of vehicles into groups, transmits control information to an on-vehicle information device of individual vehicles belonging to a group to which a processing turn of the transmission process has come, and receives responses indicating presence or absence of abnormality due to update of on-vehicle devices using the control information from the on-vehicle information device of each vehicle. The server performs the transmission process of the control information toward a group having a following turn when responses indicating presence of abnormality are a predetermined reference value or less, and, suspends transmission processes of control information toward groups having following and subsequent turns when the responses indicating presence of abnormality are more than the predetermined reference value.

The display device is loaded on a vehicle, and connects the communication with the information processing terminal via the connection unit. Specifically, the display device obtains and displays an application image outputted by the information processing terminal. Also, the display device obtains, from the information processing terminal, a property of the application generating the application image. The property of the application may include information whether or not the application is controllable by an external device, the reliability of the application, the genre of the application and the display appropriateness. Then, the display device regulates the display of the application image based on the obtained property of the application and the running state of the vehicle.
