  • Patent number: 11514730
    Abstract: In a hybrid vehicle, each of an engine and an MG1 is mechanically coupled to a drive wheel with a planetary gear being interposed. The planetary gear and an MG2 are configured such that motive power output from the planetary gear and motive power output from the MG2 are transmitted to the drive wheel as being combined. A controller makes WGV diagnosis for diagnosing whether or not a waste gate valve is normally controllable by issuing an instruction to a WGV actuator while the controller stops combustion in the engine and controls the MG1 and the MG2 in coordination to perform motoring of the engine during traveling of the hybrid vehicle.

  • Patent number: 11498546
    Abstract: When a prescribed execution condition is satisfied at the time of transition from HV traveling (that is, traveling performed by an engine and a motor with generation of traveling driving force by the engine) to EV traveling (that is, traveling performed by the motor without generation of traveling driving force by the engine), a controller of a hybrid vehicle performs motoring (or a self-sustaining operation) of an engine and thereafter stops the engine.

  • 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: 11396944
    Abstract: A transmission system configured to perform a gear change based on a shift operation by an operator is provided, which includes a power transmission system including a transmission and configured to transmit an engine driving force to wheels, a shift operation detecting module, and a transmission controlling module adapted to be executable of a manual rotation synchronizing mode having first and second steps. In the first step, when a first shift operation for changing the transmission to a lower-speed side is detected, the transmission controlling module sends a control signal to a connecting-and-disconnecting mechanism provided to the power transmission system to suspend the transmission of the driving force. In the second step, when a second shift operation is detected, the transmission controlling module sends a control signal to the connecting-and-disconnecting mechanism to resume the transmission of the driving force while the transmission is switched to the lower-speed side.
