Vehicle-road interaction technology-based energy-saving driving strategy prompt system and working method thereof

Abstract

The invention discloses a vehicle-road interaction technology-based energy-saving driving strategy prompt system and a working method thereof. The system comprises a radio frequency transmitter which is arranged at an intersection and can acquire traffic information of the intersection, and an energy-saving driving strategy prompt device which is arranged on a vehicle, wherein the device consistsof a software part and a hardware part; the hardware part consists of a microprocessor, a radio frequency receiver, a vehicle-mounted global position system (GPS) navigator and a display and / or a voice prompter; and the software part mainly refers to an energy-saving driving strategy operating module. When the vehicle enters a road section with a signal control intersection ahead, the energy-saving driving strategy prompt device matches real-time data of the vehicle-mounted GPS navigator with the received traffic information, processes the data and the information through the energy-saving driving strategy operating module to acquire a vehicle energy-saving driving strategy, and prompts the vehicle energy-saving driving strategy to a driver through the display and / or the voice prompter. By the system, the aims of energy-saving driving and exhaust emission reduction can be fulfilled.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation. Background technique [0002] In today's world, many international and social issues are energy issues in the final analysis. Since the invention of automobiles, people's living standards have been greatly improved and the progress of human society has been promoted. But it has also brought great negative impacts, such as consuming a lot of energy, and causing serious traffic congestion and environmental pollution. [0003] At present, the research on automobile energy saving is mainly carried out from two aspects: "open source" and "throttle". "Open source" refers to finding various new energy sources to replace petroleum energy; "throttling" mainly refers to improving the fuel economy of vehicles, such as optimizing vehicle shape design, improving power system and transmission system, and adopting advanced electronic technology. However, the "open source" technology is not...

AI Technical Summary

Problems solved by technology

However, the "open source" technology is not yet mature, and the comprehensive benefits are not clear, while the research and development costs of the "throttling" technology are relatively high

[0004] When the vehicle is driving, especially when driving in the city, since the driver does not know the traffic situation at the intersection ahead, he may perform frequent manipulations on the vehicle during the process of passing the intersection ahead, such as acceleration, deceleration, Stopping and starting, such manipulation will cause a large waste of energy and exhaust emissions for the vehicle
