Publication number: 20230376035Abstract: The method of the present disclosure is a method for operating an on-demand vehicle that travels by autonomous driving on a single lane on which a regular service vehicle is operated. According to the method of the present disclosure, first the on-demand vehicle is moved to a meeting place with a user in response to receiving a reservation for the on-demand vehicle from the user. Next, an available waiting time of the on-demand vehicle at the meeting place is calculated based on a regular operation schedule of the regular service vehicle. Then, the on-demand vehicle is moved from the meeting place so as not to affect operation of the regular service vehicle when the available waiting time elapses without the user appearing at the meeting place.Type: ApplicationFiled: May 16, 2023Publication date: November 23, 2023Applicant: Woven by Toyota, Inc.Inventors: Koki MATSUSHITA, Ryota NAKABAYASHI, Motoaki UMAKOSHI, Rika OIKE

Publication number: 20230376871Abstract: The method of the present disclosure is a method for operating a regular service vehicle and an on-demand vehicle that travel by autonomous driving on a single lane having a plurality of overtaking places including a stop. According to the method, it is predicted that the on-demand vehicle is prevented from arriving at a location of a user of the on-demand vehicle at an optimal time by the regular service vehicle. When a passenger is on the regular service vehicle, an arrival time of the on-demand vehicle at the location of the user is delayed from the optimal time to cause the regular service vehicle to travel according to a regular operation schedule. When no passenger is on the regular service vehicle, the regular service vehicle is delayed from the regular operation schedule to cause the on-demand vehicle to arrive at the location of the user at the optimal time.Type: ApplicationFiled: May 22, 2023Publication date: November 23, 2023Applicant: Woven by Toyota, Inc.Inventors: Koki MATSUSHITA, Ryota NAKABAYASHI, Rika OIKE, Motoaki UMAKOSHI

Patent number: 10087856Abstract: An internal combustion engine includes cylinders that are divided into a first cylinder group and a second cylinder group, a cylinder reduction mechanism that holds intake valves and exhaust valves of the first cylinder group in closed states so as to establish a reduced-cylinder state. When the engine is stopped in the reduced-cylinder state, the electronic control unit provided in the engine starts the engine by ignition, by executing fuel injection and ignition in an expansion-stroke cylinder. When the first cylinder group includes an exhaust-stroke cylinder, the engine is started by ignition through fuel injection and ignition in the expansion-stroke cylinder, after a piston is moved in a reverse direction through fuel injection and ignition in the exhaust-stroke cylinder. When the first cylinder group does not include the exhaust-stroke cylinder, the engine is started by ignition, through fuel injection and ignition in the expansion-stroke cylinder and an intake-stroke cylinder.Type: GrantFiled: June 8, 2017Date of Patent: October 2, 2018Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Koki Matsushita

Patent number: 8977461Abstract: When the operating speed of an accelerator pedal is higher than a given operating speed, a target acceleration as a target output value is multiplied by a gain so that an absolute value of the target acceleration is increased; therefore, a large acceleration requested by the driver can be achieved. The gain by which the target acceleration is multiplied is set to 1 when the target acceleration is about zero, so as to resume a condition where the absolute value of the target acceleration is not increased. Thus, when the control of increasing the absolute value of the target acceleration with the gain is stopped, an elevation change is less likely or unlikely to occur in the actual acceleration. Consequently, a desired acceleration is generated without causing the driver to feel uncomfortable during driving of the vehicle.Type: GrantFiled: December 29, 2010Date of Patent: March 10, 2015Assignee: Toyota Jidosha Kabushiki KaishaInventors: Koki Matsushita, Shin Noumura, Ken Koibuchi

Patent number: 8886431Abstract: In vehicle running control that, at the time of controlling driving force, determines whether an operating speed that is a speed at which a driver operates an accelerator operator (10) is higher than or equal to a threshold and that changes details of control over the driving force on the basis of a result of the determination, the threshold is set on the basis of operation information, other than the operating speed of the accelerator operator (10), within information related to operation of the accelerator operator (10). In the vehicle running control, at the time of controlling the driving force, details of control over the driving force are changed on the basis of the operating speed that is the speed at which the driver operates the accelerator operator (10) and a stroke amount that is an operation amount of the accelerator operator (10) when the driver has operated the accelerator operator (10).Type: GrantFiled: January 4, 2011Date of Patent: November 11, 2014Assignee: Toyota Jidosha Kabushiki KaishaInventor: Koki Matsushita
