Urban electric bus route node energy consumption calculation method based on OBD

Abstract

The invention discloses an urban electric bus route node energy consumption calculation method based on an on-board diagnostic (OBD) system, which comprises the following steps of: firstly, extracting space coordinate information of each node, and matching track points in actual operation of an electric vehicle by utilizing acceleration and distance; and then the energy consumption of three states of approaching, stopping and leaving within the node range and the total energy consumption of all nodes are calculated through the voltage and the current, and data support is provided for reducing the energy consumption and the cost of the electric bus and establishing a green and low-carbon public transportation system. According to the method, the energy consumption of the bus station and the intersection node in the electric bus route can be more accurately calculated through the speed, acceleration, voltage, current and other data collected by the OBD in combination with the longitude and latitude of the track point.

Description

technical field [0001] The invention relates to a method for calculating the energy consumption of a line node of an urban electric bus, in particular to an OBD-based method for calculating the energy consumption of a line node of an urban electric bus. Background technique [0002] The transportation industry is one of the main industries of energy consumption in my country. In the face of energy and environmental issues, it has become a social consensus to develop new energy vehicles featuring low energy consumption and low emissions. The state has issued a series of policies to promote the priority development of public transportation. New energy buses, especially electric buses, are rapidly replacing fuel-powered buses. In the future, my country will realize the full electrification of vehicles in the public sector. [0003] Although electric buses do not account for a high proportion of motor vehicle ownership, only 1.25% in 2020, due to the special operating environmen...

Problems solved by technology

At present, on the one hand, the existing research on energy consumption or emissions of bus line nodes is concentrated in the field of fuel vehicles, while there are certain differences in the operation process of electric buses and fuel buses, such as faster speed increase, no need to engage gears, and no idle state etc.; on the other hand, the energy consumption calculation of electric buses at the line nodes is relatively extensive, and the precision needs to be further improved
