  • Patent number: 10160348
    Abstract: A starting control device is provided for an electrically driven vehicle having an electric motor and an internal combustion engine as drive sources and a transmission shifts and transmits an output of the electric motor to a drive wheel. The starting control device is configured to suppress an abrupt increase in the rotation of the electric motor at the time of an EV start of the vehicle from a released state of a starting dog clutch. In the electrically driven vehicle, an EV start is carried out by transmitting the output of the first motor/generator (MG1) to the drive wheel via a starting dog clutch that is meshingly engaged. The output of the first motor/generator is limited until the starting dog clutch comes into a meshed state in which the transmission transmits drive power at the time of start from a released state of the starting dog clutch.
