Gearshift control for dry dual-clutch transmissions
In this paper a smooth control algorithm for gear shifting is proposed for improving longitudinal dynamic performance during dry dual-clutch engagements while shifting up or down takes place based on measurements of engine speed and clutch speed, and on estimation of the dual-clutch engaging torque. Simulation effort is made by Matlab/Simulink for transient responses of the overall propulsion s...
متن کاملPredicting the launch feel of automatic and dual clutch transmissions
The Powertrain Dynamics Library (PTDynamics) has been developed using a new approach to modelling the mechanics of rotating MultiBody systems. This paper will highlight the recent developments within the PTDynamics library with a focus on the dynamic torque converter and wet clutch models that enable the prediction of the launch feel of automatic and dual clutch transmission equipped vehicles. ...
متن کاملAutomation of Manual Transmissions
The gears are changed automatically with the automated shift transmission. In contrast to the automatic step transmission, the ASG must interrupt the tractive force when shifting. This is more clearly detectable the higher the tractive force that is interrupted. For this reason, it can be surmised that ASG will be accepted mainly in small cars. The increasing use of electronic throttle simplifi...
متن کاملSystem Modeling and Control of a Clutch Actuator System for Dual Clutch Transmissions
In this paper, a clutch actuator system for DCTs is developed by integrating a brushless DC motor with mechanical subsystems. The system modeling is performed with experimental validations. However, since the developed model is based on the linear system, it may include modeling uncertainties and external disturbances. To overcome this difficulty, a cascade control structure is proposed. Theref...
متن کاملPerformance Evaluation of the Embedded System for Automated Manual Transmissions using Test Rig
Drivers are becoming more fatigued and uncomfortable as traffic densities increase, and so, can show slower reaction time. They then face the danger of traffic accidents due to their inability to cope with frequent shifting. To reduce this risk, some drivers prefer automatic transmissions to manual transmissions. However, automatic transmission requires both higher fuel consumptions and costs. ...
