The paper presents aspects concerning the modeling, driving scenarios and control structures of two classes of vehicular power train systems with continuously variable transmission (CVT). The modeling includes an analysis of the systems' components which include the spark-ignition internal combustion engine, the torque converter, the continuously variable transmission and the wheels. The CVT offers...
Electric motor's controlling algorithm decides bus acceleration ability. Under acceleration and huge resistance condition, electric motor is expected to give peak torque in a short response time. The paper analyzes the principle of the power train based on a permanent magnet DC motor with an augment-winding, develops a transient mathematical model of electric motor drive system in the acceleration...
This paper presents a robust stop-and-go control law, especially well adapted to car following scenarios in urban environments. Since many vehicle/road interaction factors (road slope, rolling resistance, aerodynamic forces) are very poorly known and measurements are quite noisy, a robust strategy is proposed within an algebraic framework. On the one hand, noisy signals will be processed in order...
