Abstract

The invention provides a new energy bus co-scheduling and energy-saving driving system and a control method thereof. In the operation process of a bus system, firstly, GPS information and power battery states of all buses on the same line and the number of passengers waiting in each station are obtained; the time for the bus to arrive at the next station is planned according to the passenger waiting state and the bus driving state, the bus adjusts the speed of the bus based on the traffic state of the current driving road and the state of a power battery, and then the bus energy management system calculates the power demand according to the required speed acceleration and further calculates the energy distribution of a power source. Compared with traditional bus scheduling, the method considers power battery recession and energy management of a new energy bus power system, and links the individual energy-saving driving of the buses with the operation efficiency of the whole bus system by using speed adjustment, thereby avoiding bus bunching and uneven driving distribution. And meanwhile, frequent acceleration and deceleration are reduced, the energy utilization efficiency of a power system is improved, and maximization of economic benefits is achieved.

Description

technical field

[0001] The present invention relates to a new energy public transportation coordinated dispatching and energy-saving driving system and its control strategy, in particular to a public transportation system and its control strategy which are coordinated by public transportation dispatching, speed regulation and energy management.

[0002] technical background

[0003] Affected by random factors such as traffic jams, traffic accidents, delays at signal intersections, and weather in the urban traffic environment, there is an uneven distribution of vehicles during the operation of urban public transport, which may even cause bus traffic to make full use of the public transport capacity. affect passenger satisfaction with public transport. As an important means to ensure the efficiency of bus operation and the reliability of bus service, bus dispatching has been widely used in bus systems since it was proposed in the 20th century. Its purpose is to restore the stab...
