Hauling vehicle and vehicle control system

A vehicle control system comprising:

• a hauling vehicle that drives an electric motor by electric power generated in a power generator to travel by driving of the electric motor;
• a loading machine that performs a loading operation on the hauling vehicle;
• and
• a server communicatively connected to the hauling vehicle,
• wherein the hauling vehicle includes:
• a position detection device that detects a position of the hauling vehicle;
• a speed detection device that detects a speed of the hauling vehicle;
• and
• a vehicle control device that controls the hauling vehicle based on map information set in advance,
• wherein the server:
• acquires a work content of the hauling vehicle corresponding to either hauling or standby based on the position of the hauling vehicle verified with the map information and the speed of the hauling vehicle transmitted from the hauling vehicle, and calculates a work progression of a loading operation to the hauling vehicle by the loading machine or a work progression of a preceding vehicle that travels ahead of the hauling vehicle in accordance with the acquired work content;
• and
• calculates a period from a predicted time at which the work progression exceeds a predetermined proportion until a predicted time at which the hauling vehicle starts acceleration based on the calculated work progression as an acceleration preparation time, and
• wherein the vehicle control device of the hauling vehicle drives the power generator to generate electricity during the acceleration preparation time based on the acceleration preparation time calculated in the server.
