Publication number: 20230023013Abstract: A remote driving taxi system provides a mobility service using remote driving taxis that are driven by remote drivers. Each of the remote driving taxis includes a display lamp configured to indicate whether the remote driving taxi is currently available. Management information includes use states of the remote driving taxis and assignment states between the remote driving taxis and the remote drivers. The remote driving taxi system puts on the display lamp of the remote driving taxi to which the remote driver has already been assigned and that is currently available, based on the management information. Further, the remote driving taxi system puts off the display lamp of the remote driving taxi to which the remote driver has already been assigned and that is currently unavailable, based on the management information.Type: ApplicationFiled: June 8, 2022Publication date: January 26, 2023Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Toru NISHITANI, Rio SUDA, Hiroshi YONENAGA, Hidekazu SASAKI, Tatsushi TAKENAKA, Shun OTA, Akihiro KUSUMOTO

Publication number: 20230014472Abstract: A matching system that matches a first vehicle requiring substitution when being at least either loaded into or unloaded from a parking place and a remote driver driving the first vehicle as a substitute through remote operation includes a terminal and a server. The terminal transmits substitution request information to the server. The server that has received the request information transmits waiting time information to the terminal. The terminal notifies a user or a staff of the received waiting time information, accepts a waiting time information approval or additional fee payment instructions, and settles the additional fee through cooperation with the server, upon receiving the payment instructions. The server changes the turn of the first vehicle in a queue for the remote operation service such that the first vehicle is prioritized more than a second vehicle that has not paid the additional fee, upon completing the additional fee settlement.Type: ApplicationFiled: June 7, 2022Publication date: January 19, 2023Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Toru NISHITANI, Rio SUDA, Hiroshi YONENAGA, Hidekazu SASAKI, Tatsushi TAKENAKA, Shun OTA, Akihiro KUSUMOTO

Publication number: 20220227412Abstract: In a steering system including a steering operation mechanism, a second actuator, a steering angle sensor, a steering torque sensor, and a steering operation control device and a control method for the steering system, only a drive assist target steered angle (first target steered angle) is reflected in a final target steered angle when a torque sensor value (actual steering torque) detected by the steering torque sensor is equal to or less than an intervention threshold. When the magnitude of the torque sensor value is more than the intervention threshold, the rate of reflection (distribution ratio) of a driver target steered angle (second target steered angle) in the final target steered angle is raised as the torque sensor value is increased, and the rate of reflection of the driver target steered angle in the final target steered angle is lowered as the magnitude of the torque sensor value is decreased.Type: ApplicationFiled: November 30, 2021Publication date: July 21, 2022Applicants: TOYOTA JIDOSHA KABUSHIKI KAISHA, JTEKT CorporationInventors: Kosuke Akatsuka, Yoshio Kudo, Rio Suda, Isao Namikawa, Takashi Kodera

Patent number: 9895978Abstract: A braking force control method that is applied to a vehicle in which regenerative braking force and friction braking force are applied to the front wheels. When the braking slip quantity of one of the front wheels that is supplied with regenerative braking force exceeds a reference value, with the instance being a reference time point, the friction braking force of the front wheels is controlled so as to increase while the regenerative braking force being controlled so as to be a provisional target regenerative braking force that is lower by a prescribed value than the regenerative braking force of the front wheels at the reference time point. When a decision is made that a prescribed period of time has passed since the reference time point, the regenerative braking force is gradually decreased and the friction braking force is gradually increased.Type: GrantFiled: October 30, 2014Date of Patent: February 20, 2018Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Rio Suda

Patent number: 8457857Abstract: A first stroke sensor and a second stroke sensor in a braking control device detect the pedal depression amount. A brake ECU calculates a target wheel cylinder pressure by utilizing the detected pedal depression amount, and increases/decreases the wheel cylinder pressure by controlling the hydraulic actuator so as to achieve the calculated target wheel cylinder pressure. The brake ECU determines whether the brake pedal has been sharply depressed, by utilizing the pedal depression amount detected within a range thereof that is smaller than the pedal depression amount. If it is determined that the brake pedal has been sharply depressed, the brake ECU relaxes the restriction on the hydraulic pressure gradient at the time of increasing the wheel cylinder which is imposed when the brake pedal has not been sharply depressed.Type: GrantFiled: May 7, 2009Date of Patent: June 4, 2013Assignee: Toyota Jidosha Kabushiki KaishaInventor: Rio Suda
