Road traffic energy-saving method based on probe vehicle technology

Abstract

The invention provides a road traffic energy-saving method based on probe vehicle technology. The road traffic energy-saving method includes the following steps: a. a probe vehicle-mounted terminal collects vehicle information of number, location, speed, time, direction and brake frequency regularly when a vehicle runs and sends the information to a data center via cellular mobile communication technology, b. a road is divided into sections and road section collection is obtained, historical data of the probe vehicle is extracted, historical average brake frequency and historical brake speed on each road section at different time intervals is counted, and frequently braking road section is found out and is added to a fuel-saving management road section collection, and c. when the vehicle runs on a certain road section, the data center matches the road section on which a driver is, and if the road section belongs to the fuel-saving management road section, the center data judges whether the current speed of the probe vehicle is reasonable and sends the optimum speed on the road section to the driver automatically if the current speed of the prober vehicle is unreasonable. The road traffic energy-saving method based on the probe vehicle technology is capable of sending road traffic energy-saving information to the driver, not only is driving behavior of the driver regularized, but also purpose of energy conservation and consumption reduction are achieved.

Description

【Technical field】 [0001] The invention relates to an energy-saving method for road driving based on floating car technology. 【Background technique】 [0002] With the continuous opening of high-speed rail and bullet trains, it has caused a serious impact on the national road passenger transportation market, and the rising oil price and labor cost have made the operation of transportation companies more difficult, and the issue of fuel consumption management has attracted more and more attention from the transportation industry. . Therefore, a road driving energy-saving method based on floating car technology is proposed. During the driving process of the vehicle, the driver adjusts the driving speed of the vehicle in advance according to the real-time road conditions and traffic conditions, so that the vehicle can obtain good driving performance and fuel consumption. economic performance. [0003] The public date is 2011.05.11, and its publication number is CN102055802A Chi...

Problems solved by technology

This patent mainly uses the driving data collected by the CAN bus to obtain the running information of the vehicle in real time, but ignores the influence of the actual road conditions on the driving behavior of the driver; However, it is impossible to remind the driver in time to keep the engine in the best working condition at a reasonable speed and gear to adapt to different road conditions and achieve real-time energy saving.
