Publication number: 20240067219Abstract: A method for controlling a mobile vehicle comprises the steps of selecting a control mode for autonomous driving of the mobile vehicle and transmitting information on the selected control mode to the mobile vehicle. The control mode includes a first mode and a second mode of which a restriction on a driving safety is stricter than that of the first mode. The step of selecting the control mode comprises the steps of determining whether a remote support for the mobile vehicle is required, and selecting the first mode as the control mode when it is determined that the remote support is not required whereas selecting the second mode as the control mode when it is determined that the remote support is required.Type: ApplicationFiled: June 28, 2023Publication date: February 29, 2024Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Narihito YAMAZATO, Kentaro ICHIKAWA, Maiko HIRANO, Yoshitaka ADACHI, Koji TAGUCHI

Publication number: 20230376031Abstract: A method to perform remote operation of a mobile vehicle is provided. In this method, data of two types of camera images whose imaging ranges partially overlap each other and data of operation content in the remote operation are acquired. Further, based on the data of the operation content, the position in the vertical direction at which the two types of the camera images are combined is set. Further, at least one of the two types of the camera images is moved in the vertical direction such that the two types of the camera images are combined at the set position in the vertical direction, and the two types of the camera images are combined. Then, a composite image of the two types of the camera images is output from a display of a remote operation device.Type: ApplicationFiled: March 17, 2023Publication date: November 23, 2023Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Narihito YAMAZATO, Koji TAGUCHI, Maiko HIRANO, Kentaro ICHIKAWA, Yoshitaka ADACHI, Kentaro TAKEMURA, Toshiki HORITA

Publication number: 20230324908Abstract: An autonomous driving control device is capable of starting an autonomous driving control without an operation of a driver and reducing a possibility that the driver can not start manual driving. An autonomous driving control is switched to manual driving when a determination section determines that the amount of operation by the driver is equal to or greater than a first threshold, before a predetermined time elapses since the autonomous driving control is automatically started. An autonomous driving control is switched to a manual driving when the determination section determines that the amount of operation by the driver is equal to or greater than a second threshold that is greater than the first threshold, after the predetermined time elapses.Type: ApplicationFiled: May 31, 2023Publication date: October 12, 2023Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Kentaro ICHIKAWA, Bunyo OKUMURA, Maiko HIRANO

Publication number: 20230259127Abstract: According to the remote assistance method of the present disclosure, first, a positional relationship between the vehicle having an autonomous traveling function and an object present around the vehicle at a future time beyond a current time is displayed spatially on a display device, the positional relationship being predicted based on a path plan for autonomous traveling created by the vehicle and information on the object. Next, assistance content input from a remote operator is transmitted to the vehicle. Then, remote assistance corresponding to the assistance content is executed in the vehicle in response to confirmation that the positional relationship between the vehicle and the object displayed on the display device when the assistance content is input is realized after the vehicle receives the assistance content.Type: ApplicationFiled: January 27, 2023Publication date: August 17, 2023Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Maiko HIRANO, Yoshitaka ADACHI, Kentaro ICHIKAWA, Koji TAGUCHI, Narihito YAMAZATO

Publication number: 20220355827Abstract: A remote assistance management system is in communication with autonomous traveling vehicles for letting an operator provide remote assistance in response to an assistance request from a vehicle. The system predicts an occurrence of an assistance request in future based on operation states of the vehicles, and categorize a cause of an assistance request predicted to occur into a first category cause that lasts for a long time and a second category cause that lasts only for a short time. The system receives an assistance request from the vehicles. In response to acquiring a first assistance request of which the cause is the first category cause from a first vehicle, the system transmits a first command signal for the first vehicle that is decided by an operator to the first vehicle, and applies the first command signal to another vehicle from which the first assistance request is predicted to occur.Type: ApplicationFiled: May 3, 2022Publication date: November 10, 2022Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Maiko HIRANO, Koji TAGUCHI, Kentaro ICHIKAWA, Yoshitaka ADACHI

Publication number: 20220357738Abstract: A remote assistance management system is in communication with a plurality of autonomous traveling vehicles for letting an operator provide remote assistance in response to an assistance request from a vehicle. The system predicts, for each vehicle, an occurrence of an assistance request in future based on an operation state of each vehicle and calculates a predicted assistance period for each assistance request predicted to occur. When more than a predetermined number of overlapping assistance requests of which predicted assistance periods overlap at the same time are predicted to occur, the system instructs to excess vehicles a change of a traveling mode from a first traveling mode being a normal traveling mode to a second traveling mode for avoiding or delaying the occurrence of an assistance request, the excess vehicles being vehicles in excess of the predetermined number among vehicles from which the overlapping assistance requests are predicted to occur.Type: ApplicationFiled: April 18, 2022Publication date: November 10, 2022Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yoshitaka ADACHI, Kentaro ICHIKAWA, Koji TAGUCHI, Maiko HIRANO
