Road grade estimation for look-ahead vehicle control using multiple measurement runs
Look-ahead cruise controllers and other advanced driver assistance systems for heavy duty vehicles require high precision digital topographic road maps. This paper presents a road grade estimation algorithm for creation of such maps based on Kalman filter fusion of vehicle sensor data and GPS positioning information. The algorithm uses data from multiple passes over the same road to improve pre...
متن کاملRoad Grade Estimation for Look-Ahead Vehicle Control
Look-ahead cruise controllers and other advanced driver assistance systems for heavy duty vehicles require high precision digital maps. This contribution presents a road grade estimation algorithm for creation of such maps based on Kalman filter fusion of vehicle sensor data and GNSS positioning information. The algorithm uses data from multiple traversals of the same road to improve previously...
متن کاملEstimation of Vehicle Mass and Road Grade
This thesis describes development of a real-time-implementable algorithm for simultaneous estimation of a heavy vehicle’s mass and time-varying road grade and its verification with experimental data. Accurate estimate of a heavy vehicle’s mass is critical in several vehicle control functions such as in transmission and stability control. The goal is to utilize the standard signals on a vehicle ...
متن کاملVehicle Mass and Road Grade Estimation using Kalman Filter
This master thesis presents a method for on-line estimation of vehicle mass and road grade using Kalman filter. Many control strategies aiming for better fuel economy, drivability and safety in today’s vehicles rely on precise vehicle operating information. In this context, vehicle mass and road grade are crucial parameters. The method is based on an extended Kalman filter (EKF) and a longitudi...
متن کاملLook-ahead Control of Heavy Trucks utilizing Road Topography
The power to mass ratio of a heavy truck causes even moderate slopes to have a significant influence on the motion. The velocity will inevitable vary within an interval that is primarily determined by the ratio and the road topography. If further variations are actuated by a controller, there is a potential to lower the fuel consumption by taking the upcoming topography into account. This possi...
