Estimation 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 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 کاملRoad Grade Estimation Results Using Sensor and Data Fusion
Advanced driver assistance systems for heavy duty vehicles, such as lookahead cruise and gearshift controllers, rely on high quality map data. Current digital maps do not offer the required level of road grade information. This contribution presents an algorithm for on-board road grade estimation based on fusion of GPS and vehicle sensor data with measurements from previous runs over the same r...
متن کاملOn Road Vehicle Detection using Association Approach
On road vehicle detection is an essential part of the Intelligent Vehicles and it is an important problem in the area of intelligent transportation systems, driven assistance systems and selfguided vehicles. The proposed algorithms should detect out all cars in realtime. Related to the driving direction, the cars can be classified into two types. Cars drive in the same direction as the intellig...
