Engine speed control for the automatic manual transmission during shift process

A Speed Control for the Reduction of the Shift Shocks in Electric Vehicles with a Two-Speed AMT

“…Therefore, speed control is applied as a method for speed synchronization in the shifting sections. Although existing internal combustion engine vehicles equipped with existing AMT have been applied with speed control, since this speed control is a simple PI control of the amount of throttle valve opening, it cannot be applied to EVs as is [16], [17]. In addition, although speed control through speed command feed-forward compensation was proposed in the case of EVs applied with an AMT, the controller design is difficult because there is no concrete mention of gains from the feed-forward compensation, and single loop controllers, where the driving voltage is the speed controller outputs, were applied instead of general dual loop controllers [18].…”

“…10 is shown in equation (17). At this time, if it exists that the error of the B for the actual load system and the B* for the aware value, the transfer function of block is the same as equation (18).…”

Design and implementation of an engine control strategy during gear shifting process of automated manual transmission (amt) for improvement of shift quality and fuel efficiency

“…al. in Ref [3] put forward that in automated mechanical transmission the shift quality can be significantly improved by means of the control of the engine speed. The engine speed control is be divided into upshift control and downshift control.…”
