Vehicle robot drivers are widely used in automotive tests especial for some tests on automotive chassis dynamometer. However, China has less technology accumulations than west developed countries in the field of research and development of robot driver. In order to promote the developments of the domestic robot driver technology, a vehicle robot driver based on servo motor control was developed for automobile chassis dynamometer test, its system composition, functional features, and key technologies in developing process were expounded specifically in this paper.
The article presents calculations of exhaust emissions and fuel consumption under test conditions on a chassis dynamometer test bench. The study describes the realization of the tests and the methodology of the calculation of the exhaust gas flow and the estimation of the fuel consumption based on exhaust emissions. The presented research results and their analysis describe the emission scale of selected gaseous fumes components during full engine load and the fuel consumption associated with such tests. Similar emissions occur during a rapid acceleration of a vehicle in road conditions.
