  • Patent number: 11450155
    Abstract: When a traveling state of a vehicle is switched, the vehicle requests delivery of an update program from an OTA server. For example, when the vehicle travels with an occupant on board, the vehicle requests delivery of an update program for manned vehicle traveling from the OTA server. When the vehicle travels with an occupant not on board, the vehicle requests delivery of an update program for unmanned vehicle traveling from the OTA server. When the OTA server receives the request for delivery of the update program for manned vehicle traveling/unmanned vehicle traveling, the OTA server delivers the requested update program for manned vehicle traveling/unmanned vehicle traveling to the vehicle. The vehicle updates a diagnosis program using the received update program for manned vehicle traveling/unmanned vehicle traveling.

  • Patent number: 11444551
    Abstract: An object of the present invention is to improve availability when a power is lost. In a power conversion device 1, a gate drive power supply circuit 50 can supply a gate drive power within a predetermined normal voltage range. A backup power supply circuit 70 supplies the gate drive power to a lower arm gate circuit 40 when a voltage of the gate drive power applied from the gate drive power supply circuit 50 to the lower arm gate circuit 40 falls below a normal voltage range. When the gate drive power is supplied from the backup power supply circuit 70, the lower arm gate circuit 40 drives a lower arm switching circuit 22 in a short state in which all switching elements of the lower arm switching circuit 22 are turned on.

  • Patent number: 11433911
    Abstract: When a diagnostic period of a specific failure arrives, a management center transmits, to a vehicle, an instruction to order execution of a failure diagnosis of the specific failure. When an ECU of the vehicle receives the instruction to order execution of the failure diagnosis from the management center, the ECU of the vehicle determines whether or not the failure diagnosis can be executed. When the failure diagnosis cannot be executed, the ECU causes the vehicle to continue traveling without executing the failure diagnosis, and ends a process. In this case, the ECU postpones the failure diagnosis in the current diagnostic period, and executes the failure diagnosis when a next diagnostic period arrives. When the ECU determines that the failure diagnosis can be executed, the ECU executes the failure diagnosis.

  • Publication number: 20220069370
    Abstract: An ECU calculates a surface potential of a negative electrode active material relative to a lithium reference potential, according to a battery model for calculating lithium concentration distribution inside the negative electrode active material. The ECU calculates a voltage drop amount associated with charging of a battery, using a charging current to the battery and a reaction resistance, and calculates a negative electrode potential by subtracting the voltage drop amount from the surface potential. The ECU corrects the negative electrode potential, using an SOC of the battery, an average current in a charging period of the battery, and an integrated current in the charging period.
