Publication number: 20240062224Abstract: A node of a B company updates a restriction list (S1) based on transaction data received from a platform provider, the transaction data proposing addition of a new restricted substance to the restriction list. The node of the B company starts checking processing and estimates whether or not there is possibility that the new restricted substance is contained in a C product supplied by a C company and a D product supplied by a D company (S2). The node of the B company generates transaction data that asks whether or not the new restricted substance is contained in the C product and transmits the transaction data to a node of the C company (S3).Type: ApplicationFiled: August 7, 2023Publication date: February 22, 2024Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Masahiko ISHII, Hidetaka ASANO, Keiichi KOGA, Ryota SUZUKI

Publication number: 20240037499Abstract: When information on a chemical substance is disclosed by a node of an upstream company (S11), a controller updates product composition data (S12) and determines whether or not the disclosed information on the chemical substance is to be kept secret (S13). When the controller determines that the disclosed information on the chemical substance does not have to be kept secret (NO in S13), it adds the information on the chemical substance (a restricted substance) received in S11 to update public data (S17) and generates transaction data including the public data and transmits the transaction data to a node of a target downstream company (S18).Type: ApplicationFiled: July 21, 2023Publication date: February 1, 2024Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Masahiko ISHII, Hidetaka ASANO, Keiichi KOGA, Ryota SUZUKI

Publication number: 20230342484Abstract: An information management system includes information management apparatuses belonging to A to D companies, respectively, and a platform provider. When a new chemical substance is added as a result of revision of laws and regulations etc. to chemical substances designated under the laws and regulations, the platform provider updates a restriction list and transmits transaction data that proposes update of restriction lists in distributed ledgers to the information management apparatuses. Each of the information management apparatuses approves the transaction data and updates the restriction list thereof. Each of the information management apparatuses discloses information on a chemical substance included in the updated restriction list to an information management apparatus in a downstream company.Type: ApplicationFiled: April 5, 2023Publication date: October 26, 2023Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Masahiko ISHII, Hidetaka ASANO, Akiko TAMURA, Koji HETSUGI, Ryota SUZUKI, Keiichi KOGA

Publication number: 20220383245Abstract: A node of a C company verifies transaction data received from a node of a B company, the transaction data proposing addition of a subject substance to a restriction list. When the node of the C company determines that information indicating that a new proposed subject substance falls under a restricted substance is incorrect by obtaining data on the restricted substance, for example, from the outside (a server apparatus or the like in an external group) and checking whether or not the subject substance falls under the restricted substance, the node of the C company does not approve the proposal for addition of the new subject substance to the restriction list but transmits transaction data that denies the proposal to the node of the B company (an arrow B5).Type: ApplicationFiled: May 24, 2022Publication date: December 1, 2022Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Masahiko ISHII, Hidetaka ASANO, Takuya KONDO, Ryota SUZUKI, Keiichi KOGA

Patent number: 7140697Abstract: When a driver operates an activation switch, an electric parking brake apparatus performs a parking brake activation control in order to operate an electric motor until the tension of a base wire reaches a predetermined target tension to thereby bring parking brakes into an activated state. After that, the apparatus again performs the parking brake activation control when a re-activation time, which is set in accordance with the difference between an estimated temperature of a service brake and an ambient temperature, has elapsed; when the position of a shift lever has been changed; when the height of the vehicle has changed by an amount greater than a predetermined amount; or when the driver releases a brake pedal which has been continuously operated after completion of the parking brake activation control.Type: GrantFiled: November 25, 2003Date of Patent: November 28, 2006Assignee: Advics Co., Ltd.Inventors: Keiichi Koga, Yoshikazu Tachiiri
