Abstract

The invention belongs to the technical field of energy-saving driving, and discloses a vehicle speed trajectory planning method, device and equipment and a storage medium. The method comprises the following steps: acquiring speed information and energy consumption information of each target vehicle; generating an energy consumption calculation model of the target vehicle according to the energy consumption information and the speed information; acquiring speed and vehicle distance limiting conditions, and acceleration information and speed and distance information of the speed limiting conditions in each target vehicle; establishing a constraint objective function according to the speed and vehicle distance limiting condition, the acceleration information, the speed and distance information and the state constraint condition; and planning the speed track of each target vehicle according to the energy consumption calculation model, the speed limiting condition, the acceleration information, the speed distance information and the constraint target function. Through the above mode, the energy consumption information is determined through the speed information of each target vehicle, so that the energy consumption calculation model is generated, the constraint target function is established, and the vehicle speed track of each target vehicle is planned, thereby reducing unnecessary acceleration and deceleration, and reducing the energy consumption of the vehicle.

Description

technical field [0001] The present invention relates to the technical field of energy-saving driving, in particular to a vehicle speed trajectory planning method, device, equipment and storage medium. Background technique [0002] Energy-saving driving technology can reduce unnecessary acceleration and deceleration by planning the economic speed trajectory of the vehicle, and reduce the energy consumption of the vehicle. [0003] However, energy-saving driving technology has the following disadvantages: [0004] 1. From the perspective of intelligent network connection, most of the current economic speed planning is based on the fixed speed limit and arrival time. It is rare to consider real-time acquisition of traffic information and surrounding vehicle information to adjust the speed limit and plan its own speed in real time; [0005] 2. From the perspective of vehicles, the current economic speed planning is mostly aimed at a single vehicle, and rarely considers multiple...
