Predictive cruise control system test platform and test method

Abstract

The invention provides a predictive cruise control system test platform and test method, and the method comprises the steps: enabling a test host to transmit pre-stored typical road spectrum information to a PCC system of a test vehicle through the test platform which is formed by connecting the test vehicle with a chassis dynamometer, the test host, a data collection device and a performance evaluation platform; according to the method, a performance evaluation platform is established, road slope information is sent to a chassis dynamometer in combination with information collected by a data collection device, the chassis dynamometer dynamically loads the road slope information, a test scene is provided for a test vehicle, and finally, the PCC system is evaluated through data collected by the performance evaluation platform in the test process. The method is high in safety, low in cost, high in repeatability and convenient and efficient to operate.

Description

technical field [0001] The invention relates to the technical field of automobile testing, in particular to a testing platform and a testing method for a predictive cruise control system. Background technique [0002] At present, my country's road transportation mileage ranks among the top in the world, and the carbon emissions of operational trucks, which account for 10% of the national car ownership, account for about 56% of the total carbon dioxide emissions of road traffic. The accident seriously endangers the social security and stability of our country. It can be seen that it is of great significance to reduce the fuel consumption of operating trucks and ensure driving safety through intelligent means. [0003] Predictive Cruise Control (PCC) system integrates road gradient, curvature and speed limit information, automatically outputs gear and torque, realizes the optimal control of the speed of the vehicle, and enables the operating truck to operate on multiple slopes...

Problems solved by technology

[0005] For this reason, the present invention provides a kind of predictive cruise control system test platform and test method, and the test method is to test by the test vehicle, chassis dynamometer, test host, data acquisition equipment and performance evaluation platform built on the test bench, The test host sends the pre-stored typical road spectrum information to the PCC system of the test vehicle, and sends the road slope information to the chassis dynamometer in combination with the information collected by the data acquisition equipment, so that the chassis dynamometer can dynamically load the road slope information and provide the test vehicle with Test scenarios, and finally use the performance evaluation platform to evaluate the performance of the PCC system based on the data collected during the test, solving the technical problems of difficult selection of actual road test scenarios, high test costs, poor repeatability, and unreasonable performance evaluation indicators
