Abstract: (90 Views)
A new idea is applied for damping of driveline oscillation (shunt and shuffle) created because of sudden changes in transmitting engine torque. In this case, by an actuator the dry clutch slides due to decreasing in clutch clamp force. By regulating the clutch force, it prevents the excessive torque from entering the driveline, which causes vibrations. This strategy eliminates the oscillations. Hence, the driveline dynamics which consists of the clutch model, driveline elements, backlash, and tire slip is modeled comprehensively in the MATLAB software and validated. When the vibrations are sensed by sensors, the electronic control unit directs the clutch actuator by changing the normal clutch force so the dry clutch slides and dampens the vibrations. For this idea, three controlling approaches are suggested: a rule-based controller, a pulse controller, and a linear predictive controller. Essential tests for examining driveline control performance are chosen and then the driveline performance is assayed for it. Also, one of the priorities in selecting a clutch control strategy is to increase the clutch lifetime. From the results, driveline vibrations including shunt and the shuffle can be reduced well. In addition, this idea doesn’t have the harms of the other solutions such as spark advance engine control that pollutes the air and electronic throttle control which lessens the vehicle performance. Moreover, the usage of this system is simple, especially in vehicles that have automatic manual transmission.
