发明名称 SPEED CHANGE CONTROL DEVICE OF AUTOMATIC TRANSMISSION
摘要 PURPOSE:To make reduction of a speed change shock compatible with ensurance of power performance by switching a speed change shift to such a speed change pattern, as being prevented from generating a simultaneous speed change, in the case of the speed change shift in which possibility of generating the simultaneous speed change is highly probable in the present speed change shift when a shift range is manually operated. CONSTITUTION:Such means are provided as a means for deciding a shift range, a means for deciding whether the present speed change shift is a speed change shift having high possibility of generating a simultaneous speed change or not and a means for switching the speed change shift to such a speed change pattern, as being prevented from generating the simultaneous speed change, in the case of the present speed change shift being a speed change shift having high possibility of generating the simultaneous speed change, when the shift range is manually operated. Accordingly, since the speed change shift can be changed into such a speed change pattern, as being prevented from generating the simultaneous speed change shift, in the case of likely generating the simultaneous speed change in accordance with manual switching, use of the speed change shift is effectively cut when a speed change shock is possible to especially increase, and reduction of the speed change shock and ensuring of power performance can be compatibly attained.
