Abstract

The invention discloses an energy-saving driving control method for a networked vehicle under a multi-signal-lamp road condition based on a pseudo-spectral method, relates to the technical field of intelligent traffic, and solves the technical problems that vehicle speed planning is not economical enough and the efficiency of a control method is not high. According to the technical scheme, the economical running speed of the vehicle at the multi-signal-lamp intersection is planned based on the pseudo-spectral method, unnecessary starting and stopping of the vehicle at the signal lamp intersection can be reduced, and therefore the economical efficiency, comfort and traffic efficiency of the vehicle are improved. The speed planned by the pseudo-spectral method can reach an energy saving rate similar to that of a dynamic planning method, and the solving time of the pseudo-spectral method is far shorter than that of the dynamic planning method.

Description

technical field [0001] The present application relates to the technical field of intelligent transportation, in particular to the economical driving control technology of intelligent networked vehicles, and in particular to a method for energy-saving driving control of networked vehicles under road conditions with multiple signal lights based on a pseudospectral method. Background technique [0002] Given the climate change and environmental pollution problems caused by transportation, countries are under intense pressure to reduce greenhouse gas emissions associated with fuel combustion, and most major auto markets have enacted limits on tailpipe carbon dioxide emissions. Connected and autonomous vehicles have great potential to improve traffic efficiency, safety and environmental sustainability, improving driving economy while improving traffic flow stability and reducing unnecessary shifting and stop-and-go of vehicles. [0003] Under the urban road network, signal lights...
