Patent number: 11951859Abstract: A navigation server includes a processor. The processor is configured to derive one of a first route and a second route as a route from a place of departure to a destination of a vehicle in accordance with a remaining level of a travel battery of the vehicle. The first route includes a first road provided with a first non-contact electric power feeder. The second route includes a second road provided with a second non-contact electric power feeder that is different in electric power feed capability from the first non-contact electric power feeder. The processor is configured to output the derived route as a recommended route to a terminal associated with the vehicle.Type: GrantFiled: August 31, 2021Date of Patent: April 9, 2024Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Ayano Kimura, Hikaru Shiozawa, Toshiya Hashimoto, Chuya Ogawa, Yuta Maniwa

Patent number: 11795884Abstract: A control device is applied to an internal combustion engine equipped with an electric heating catalyst system provided with an EHC. The control device executes a preheating process to warm up an exhaust gas reduction catalyst prior to a start of the internal combustion engine by supplying electric power to the EHC, when the control device determines that a temperature of the exhaust gas reduction catalyst is lower than an activation temperature. The control device executes a determination process for determining whether water is adhered to a catalyst carrier. The control device starts the internal combustion engine without executing the preheating process when the control device determines by the determination process that water is adhered to the catalyst carrier, even when the control device determines that the temperature of the exhaust gas reduction catalyst is lower than the activation temperature.Type: GrantFiled: August 29, 2022Date of Patent: October 24, 2023Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Shigemasa Hirooka, Koichi Kitaura, Yoshio Yamashita, Shingo Korenaga, Katsuhiro Ito, Hikaru Shiozawa

Patent number: 11492941Abstract: A controller is applied to an internal combustion engine in which an electrically heated catalyst that is heated when supplied with electric power is installed in an exhaust passage. The controller is configured to perform a preheating process of warming up a first exhaust catalyst by supplying electric power to the electrically heated catalyst through control over a power supply before a start of the internal combustion engine. The controller is configured to, when an insulation resistance of the electrically heated catalyst at a start of the preheating process is lower than a threshold, perform the preheating process while decreasing a voltage supplied to the electrically heated catalyst.Type: GrantFiled: March 23, 2022Date of Patent: November 8, 2022Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Shigemasa Hirooka, Koichi Kitaura, Yoshio Yamashita, Shingo Korenaga, Katsuhiro Ito, Hikaru Shiozawa

Publication number: 20220332305Abstract: A control device starts supply of electric power to a catalyst device when a state of charge of a main battery decreases to a value which is equal to or less than an optimal power-supply state of charge set based on a travel load while a vehicle is traveling in an EV travel mode. The control device corrects input electric power of the catalyst device to a value less than the value at the time of starting of supply of electric power when the travel load decreases after the supply of electric power has been started.Type: ApplicationFiled: April 4, 2022Publication date: October 20, 2022Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Shigemasa HIROOKA, Koichi KITAURA, Yoshio YAMASHITA, Shingo KORENAGA, Katsuhiro ITO, Hikaru SHIOZAWA
