TORQUE CONTROL BASED ON GEAR SHIFT - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 17718709 Titled 'TORQUE CONTROL BASED ON GEAR SHIFT'
Simplified Explanation
This abstract describes an apparatus that includes a dampening unit connected to an engine, as well as a control unit that is connected to the dampening unit. The control unit is able to detect when the transmission unit associated with the engine shifts gears. It then determines how long the dampening unit needs to absorb the torsional vibrations of the engine during the gear shift. The control unit compares this dampening duration to a preset duration for a specific gear shift. Based on this comparison, the control unit determines how much torque control is needed for the dampening unit to effectively absorb the engine vibrations. Finally, the control unit controls the dampening unit based on the determined torque control amount.
Original Abstract Submitted
An apparatus is provided with a dampening unit coupled to an engine. The apparatus further includes a control unit communicably coupled to the dampening unit. The control unit detects a gear shift in a transmission unit associated with the engine. The control unit further determines a dampening duration of the dampening unit at the detected gear shift. The dampening duration corresponds to a time taken for the dampening unit to absorb torsional vibrations of the engine at the detected gear shift. The control unit further compares the determined dampening duration at the detected gear shift with a preset dampening duration at a preset gear shift. The control unit further determines, based on the comparison, a torque control amount for the dampening unit to absorb the torsional vibrations of the engine. The control unit further controls the dampening unit based on the determined torque control amount.
