1. An on-vehicle device comprising:
a driving support device mounted in a vehicle, and configured to receive driving support information from a driving support server and execute a predetermined process for driving support;
a sub driving support server mounted in the vehicle, and including a subset of a function of the driving support server and configured to receive sensor data from an external sensor and generate a subset of the driving support information based on the received sensor data and output the generated subset of the driving support information;
a first switching device configured to give the subset of the driving support information from the sub driving support server, instead of the driving support information from the driving support server, to the driving support device in response to interruption of reception of the driving support information from the driving support server;
a second switching device configured to give the driving support information from the driving support server, instead of the subset of the driving support information from the sub driving support server, to the driving support device in response to recovery of the reception of the driving support information from the driving support server;
a state storage device that stores states inside and outside the on-vehicle device and a cooperative state with another sensor-equipped device on the basis of the driving support information; and
a server reconstruction device that is mounted in the vehicle and is configured to reconstruct the sub driving support server in response to a change in either the states inside and outside the on-vehicle device or the cooperative state with the other sensor-equipped device stored by the state storage device.
