Patent number: 11965468Abstract: A vehicle control system, a vehicle control method, and a storage medium are provided. A stopping process stops fuel supply to one or more stopping cylinders and supplies fuel to one or more remaining cylinders during a load operation of an engine. During execution of the stopping process, a compensating process compensates for a decrease in output of the one or more stopping cylinders due to the execution of the stopping process by increasing output generated by combustion in the one or more remaining cylinders. The system control circuit causes, when the engine rotation speed of the engine is the same, the output after being increased by the compensating process to decrease as a shaft torque of the crankshaft of the engine increases.Type: GrantFiled: August 7, 2023Date of Patent: April 23, 2024Assignee: Toyota Jidosha Kabushiki KaishaInventors: Shinnosuke Honda, Yoshinori Fujitake, Suguru Kumazawa, Motohiko Taniyama, Keita Sato, Yuki Iizawa, Yoshiyuki Shogenji, Yasutaka Tsuchida
