Bus driving control method and system based on cooperative adaptive cruise control

The invention provides a cooperative adaptive cruise control-based bus driving control method and system. The method comprises the following steps of: judging whether a bus is in a cooperative adaptive cruise control fleet or not; if the bus is in the vehicle fleet, determining a driving mode according to the position of the bus in the vehicle fleet; if the bus is not in the motorcade, the time interval between the bus and the adjacent bus in front of the bus is judged, and if the time interval is larger than a preset value, the bus cruises in a self-adaptive cruise control mode; when the time interval is smaller than a preset value, the bus is switched to a cooperative self-adaptive cruise control mode; on the basis of judging whether the bus is in the CACC fleet or not, the cruise mode of the bus is determined, traditional bus control is combined with CACC, the service performance of a single bus route can be improved, and the system service performance of buses on multiple routes on the same road section c
