Patent number: 10563735Abstract: There is provided an automatic transmission capable to preventing an output of a driving source in a neutral range from being transmitted to wheels without increasing the number of control valves which could fail. An automatic transmission includes a first brake, a third clutch, a third brake, a transmission control device configured to control the first brake, the third clutch, and the third brake, and a hydraulic sensor and a hydraulic switch configured to determine whether the first brake is under control of the transmission control device. When the hydraulic sensor and the hydraulic switch detect that the first brake is in an engaged state contrary to control of the transmission control device in a non-traveling range, the transmission control device switches the third clutch and the third brake to the engaged state.Type: GrantFiled: March 22, 2018Date of Patent: February 18, 2020Assignee: Honda Motor Co., Ltd.Inventors: Yuya Tachibanada, Yutaka Ishikawa, Sadahito Kajihara
