Vehicle Management System

Abstract

[Problem] To provide a vehicle management system that controls activation and stopping of a vehicle owned by a user, by a command from a management server, and includes a relay capable of being turned on by an external turn-on permission instruction, thereby improving a security function. [Solution] A vehicle management system comprises: a management server that manages an activation state of a vehicle and provides instructions to activate or stop the vehicle; a GPS receiver that is installed in the vehicle; and an in-vehicle device that is installed in the vehicle, transmits the activation state and location information of the vehicle to the management server, and controls activation and stopping of the vehicle. The in-vehicle device controls a relay that switches activation and stopping of a drive device of the vehicle. The management server determines, on the basis of the activation information and location information of the vehicle transmitted from the in-vehicle device, whether or not it is permissible to activate or stop the vehicle, and then transmits a vehicle activation command or stop command to the in-vehicle device. Then, the in-vehicle device transmits a signal for setting or resetting the relay to the relay.
