Patent number: 11203990Abstract: A vehicle equipped with an automatic stop/restart system for an internal combustion engine includes a hydraulic continuously variable transmission and a parking mechanism. The continuously variable transmission changes power of the internal combustion engine using hydraulic pressure boosted by rotational driving force of the internal combustion engine. The parking mechanism holds the vehicle stationary by locking, with a locking member, the rotation of a power transmitting member between the internal combustion engine and driving wheels when a shift position is in a parking range. In an automatic stop state of the internal combustion engine, when the shift position is in the parking range and brakes are turned off, an electronic control unit executes restart if an inclination angle of the vehicle is greater than or equal to a predetermined value, and maintains the automatic stop state if the inclination angle is smaller than the predetermined value.Type: GrantFiled: March 16, 2021Date of Patent: December 21, 2021Assignee: HONDA MOTOR CO., LTD.Inventors: Kosuke Moro, Ryuji Sato, Hiroaki Ninomiya
