Patent number: 9879762Abstract: A jump shift of an automatic transmission with multiple shift speeds such as, e.g., ten forward speeds involves operation of many engagement elements. The shifting operation for the jump shift is therefore complicated, making it difficult for the automatic transmission to respond quickly. After shifting to the seventh speed as a direct coupling speed is completed by engaging three clutches C1, C3, C4, the remaining other clutch C2 is also engaged at the seventh speed. In the case of a jump shift, e.g., a shift from the seventh speed to the fifth speed, shifting to the fifth speed is completed by disengaging the clutch C1 and performing control to disengage the clutch C3 and to engage a brake B1 with the remaining other clutch C2 kept in the engaged state. This facilitates the shifting operation from the direct coupling speed and allows the automatic transmission to respond quickly.Type: GrantFiled: December 24, 2014Date of Patent: January 30, 2018Assignees: AISIN AW CO., LTD., TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Hiroyuki Kutsubo, Nobuyuki Hirai, Masamichi Yamaguchi, Yoshimitsu Hyodo, Kenichi Tsuchida, Terufumi Miyazaki, Youhei Habata, Yoshio Hasegawa
