  • Patent number: 11427084
    Abstract: An ECU of a vehicle performs diagnosis processing for diagnosing whether or not a charge relay has stuck after end of charging of a power storage. When the diagnosis processing has not normally ended, the ECU requests connection again of a connector to a charge port for performing re-diagnosis processing for diagnosing again whether or not the charge relay has stuck. When the connector and the charge port are connected to each other again, the ECU determines whether or not it has received a charging start signal from a DC power feed facility. When the ECU has received the charging start signal, it does not perform re-diagnosis processing.

  • Patent number: 11427178
    Abstract: An HV-ECU calculates requested output torque Tec based on requested power and compares the requested output torque with controlled upper limit torque Teth. When requested output torque Tec has attained to controlled upper limit torque Teth, the HV-ECU restricts output torque of engine to controlled upper limit torque Teth and calculates actual output torque Ter at that time. Then, the HV-ECU calculates a difference (differential torque ?Te) between controlled upper limit torque Teth and actual output torque Ter. The HV-ECU learns controlled upper limit torque Teth based on differential torque ?Te.

  • Patent number: 11427096
    Abstract: A power transmitting device includes: a power transmitting unit that contactlessly transmits alternating-current power to be transmitted to a power receiving unit of a vehicle; a camera that detects a positional relationship between the power transmitting unit and the power receiving unit; and a power supply ECU. The power supply ECU is configured to perform an “alignment process” performing a process using the positional relationship detected by the camera for aligning the power receiving unit with the power transmitting unit, and a “power transmission function check process” causing the power transmitting unit to output a checking power to check whether a power transmission function of the power transmitting unit functions properly. When wireless communication is established with the vehicle, the power supply ECU initially performs the alignment process, and after it is determined that the alignment process completes alignment, the power supply ECU performs the power transmission function check process.

  • Publication number: 20220266832
    Abstract: In a vehicle drive device, a second power source is connected to a first rotating element of a differential mechanism, and the other output shaft of a first output shaft and a second output shaft is connected to a third rotating element so as to be disconnectable and connectable by a disconnection-connection mechanism. A control device places the disconnection-connection mechanism in a disconnected state. When a second traveling mode in which the third rotating element is fixed to a fixing member through engagement of an engaging element is switched to a first traveling mode in which the disconnection-connection mechanism is placed in a connected state, the control device disengages the engaging element, executes synchronous control in which rotational speeds of the other output shaft and the third rotating element are synchronized by a second power source, and switches the disconnection-connection mechanism from the disconnected state to the connected state.
