Patent number: 11934823Abstract: An electronic control system for vehicle includes a center device that manages a program update of a vehicle, and a vehicular master device that is communicable with the center device. The center device, responsive to a user giving approval for program update by using a device not being a possession owned by the user, receives approval information of the user, and stores and manages the approval information in association with vehicle information of the user. The center device transmits the approval information to the user's vehicle side. When the vehicular master device receives the approval information, the vehicular master device performs rewriting of the program.Type: GrantFiled: April 28, 2022Date of Patent: March 19, 2024Assignee: DENSO CORPORATIONInventors: Yuzo Harata, Kazuhiro Uehara, Takuya Kawasaki, Mitsuyoshi Natsume, Masaaki Abe

Patent number: 11928459Abstract: An electronic control unit includes a first process flag setting unit that is configured to set a first process flag indicative of a progress of a first process that is one of a series of processes related to a program rewrite, a second process flag setting unit that is configured to set a second process flag indicative of a progress of a second process that is an other of the series of processes related to the program rewrite, and a retry point specifying unit that is configured to specify, based on the first process flag and the second process flag, a retry point for resuming the program rewrite when the program rewrite is suspended. The retry point specifying unit is further configured to store an amount of the update data that has been written until the program rewrite was suspended and request the vehicle master device to transfer the update data based on the stored amount of the update data when resuming the program rewrite.Type: GrantFiled: February 8, 2021Date of Patent: March 12, 2024Assignee: DENSO CORPORATIONInventors: Yuzo Harata, Kazuhiro Uehara, Mitsuyoshi Natsume, Takuya Kawasaki

Patent number: 11465451Abstract: A tyre includes a tread portion including a first land portion having a circumferentially extending first edge and a circumferentially extending second edge on its ground contacting surface. The first land portion is provided with sipes each extending from the first edge to the second edge. The sipes include bent sipes each including two or more sipe elements joined with each other to form a bent portion. The bent sipes include first sipes and second sipes. Each first sipe, as the sipes elements, includes at least one first sipe element inclined in a first direction with respect to a tyre axial direction and at least one second sipe element inclined in a second direction opposite to the first direction with respect to the tyre axial direction. All sipe elements of each second sipe are inclined in the first direction with respect to the tyre axial direction.Type: GrantFiled: March 5, 2019Date of Patent: October 11, 2022Assignee: SUMITOMO RUBBER INDUSTRIES, LTD.Inventor: Yuzo Kawasaki

Patent number: 11364747Abstract: A tire that can improve braking performance on a dry road surface and wet performance is provided. The tire includes a tread portion 2. The tread portion 2 includes a shoulder land portion 5 disposed at an endmost tread edge side. The shoulder land portion 5 has a plurality of shoulder lateral grooves 10 that fully traverse the shoulder land portion 5. Each shoulder lateral groove 10 includes, in a transverse cross-section orthogonal to a longitudinal direction thereof, a bottom portion 11, a groove wall main body 12 extending from the bottom portion 11 outward in a tire radial direction, and a chamfered portion 15 between a ground-contact surface of the shoulder land portion 5 and the groove wall main body 12. The chamfered portion 15 is titled at an angle of 5 to 30° relative to a tread profile 13 obtained by extending the ground-contact surface.Type: GrantFiled: October 25, 2019Date of Patent: June 21, 2022Assignee: Sumitomo Rubber Industries, Ltd.Inventor: Yuzo Kawasaki
