A road spectrum collection system and method

Abstract

The invention relates to a road spectrum collection system and method, and belongs to the field of vehicles. The system comprises that a test vehicle and an engine controller positioned on the test vehicle; and the system further comprises a CAN message collector, and an oil consumption instrument, an attitude sensor, a GPS and a host computer connected to the CAN message collector, the oil consumption instrument, the attitude sensor and the GPS are arranged on the test vehicle, and the engine controller is connected with the CAN message collector; a route is planned according to a model of the test vehicle; and when the test vehicle runs according to the planned route, the host obtains engine controller information, attitude sensor information, GPS information and oil consumption instrument information from the CAN message collector, analyzes all the information, and obtains a target road spectrum and first oil consumption based on the planned route. Thus, the road spectrum can be collected accurately and comprehensively.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a road spectrum collection system and method. Background technique [0002] Since the development of the automobile industry, with the aggravation of the world's energy shortage and the rise of oil prices year by year, the fuel consumption of vehicles has become one of the important factors that consumers consider when buying cars. At present, China's current standards on vehicle fuel consumption limits include the Ministry of Communications standard JT 719-2008, and the standards GBT27840-2011 and GB30510-2014 issued by the Ministry of Industry and Information Technology, all of which have clear test method requirements and fuel consumption limits for vehicles. However, both of these two standards have certain limitations, and it is impossible to feed back the actual road fuel consumption of the vehicle. [0003] The standard JT 719-2008 of the Ministry of Communications uses constant-s...

Problems solved by technology

However, the existing technology has the following disadvantages: 1) There is no gear position and slope information in this cycle; 2) The commercial vehicle driving condition should have mountain road information, and the road ratio information of C-WTVC does not match the road classification ratio in my country

Due to the above factors, the fuel consumption of commercial vehicles simulated and tested according to this curve cannot represent the actual fuel consumption of real vehicles
