Patent number: 10253877Abstract: In a case where intermediate gear stage fault occurs, an electronic control unit determines, using a predetermined relationship for determining gear stage switching between a gear stage on a lower side than the intermediate gear stage by one stage and the intermediate gear stage, whether or not to execute gear stage switching between the low gear stage and a gear stage on a higher than the intermediate gear stage by one stage. For example, compared to using a relationship for determining gear stage switching between a gear stage on the higher side and the intermediate gear stage, it is possible to execute gear stage switching between a gear stage on the lower side and a gear stage on the higher side in a low vehicle speed region. Therefore, it is possible to suppress the influence on vehicle behavior.Type: GrantFiled: June 2, 2017Date of Patent: April 9, 2019Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Hiroyuki Sawada, Takahiro Kondo, Masakazu Owatari, Tatsuro Hatano, Yoshiki Ando

Patent number: 10030763Abstract: In a control apparatus for a vehicle, when it is not determined that a downshift to a second gear stage should be carried out and an accelerator depression amount change rate is equal to or smaller than a predetermined value when it is determined that a downshift to a first gear stage should be carried out, a single downshift command to the first gear stage is output. When it is not determined that the downshift to the second gear stage should be carried out and the accelerator depression amount change rate is larger than the predetermined value when it is determined that the downshift to the first gear stage should be carried out, a current gear stage is maintained. Therefore, a skip downshift to the second gear stage can be carried out when it is determined that the downshift to the second gear stage should be carried out.Type: GrantFiled: April 12, 2017Date of Patent: July 24, 2018Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Hiroyuki Sawada, Takahiro Kondo, Yoshiki Ando

Patent number: 8777811Abstract: A vehicular shift control device is provided that controls the input rotational speed of a geared transmission by adjusting the rotational speed of a drive source at downshift of the geared transmission. The greater the deceleration of the vehicle, the smaller is set the change gradient of the input rotational speed of the geared transmission. Therefore, even if the decrease rate of the post-shifting synchronization rotational speed is great, the incident angle ? of the input rotational speed of the geared transmission relative to the post-shifting synchronization rotational speed is maintained as a large angle. Even when the deceleration of the vehicle during downshift is great, the downshift is smoothly executed without producing an excessive synchronization shock.Type: GrantFiled: June 17, 2009Date of Patent: July 15, 2014Assignee: Toyota Jidosha Kabushiki KaishaInventors: Toshinari Suzuki, Kenta Kumazaki, Yoshiki Ando, Masakazu Kaifuku
