Abstract: This paper describes in detail the development and test process of the predictive fuel-saving cruise system of commercial vehicles, which is mainly based on the vehicle positioning information, combined with the front road slope, curvature, heading and other data extracted from the map data of autonomous driving assistance system, and actively controls the cruise speed of the vehicle through the comprehensive decision-making of the control unit, so as to pass through the ups and downs section at the optimal speed. The test results show that compared with ordinary constant speed cruise, this technology can effectively improve fuel economy, through the road test verification under the high-speed logistics condition of the real vehicle.
