The invention discloses a block chain-based cooperative path planning and scheduling method in a cognitive Internet of Vehicles scene, which considers the scene of hybrid driving of a networked automatic driving vehicle and a networked manned vehicle, jointly optimizes the load balance of a vehicle traffic road network and an edge computing node, proposes a block chain-based cooperative framework, and improves the cooperative path planning and scheduling efficiency. Therefore, path planning and scheduling of vehicle cooperation are supported. In addition, a task processing model is established, and influence factors of time delay calculation of the proposed collaboration framework are analyzed. A traffic condition and load distribution model is established on the basis of sensed traffic and network states, a joint optimization problem is modeled, a distributed reinforcement learning algorithm based on Q-Learning is proposed to perform cooperative path planning and scheduling, and active load balance of road infrastructures and mobile edge computing nodes is realized to minimize driving time and computing time delay. According to the invention, different service requirements of different types of vehicles are met, and the calculation complexity is reduced.
