Abstract
A vehicle driving control device for a vehicle includes a control unit configured to stop operation of an electric motor driving device driving an electric motor at a time a rotary element is fixed to be unable to rotate by an engagement by an engaging mechanism, and to recover the operation of the electric motor driving device at a time a predetermined condition based on a parameter relating to a driving of the vehicle is satisfied before releasing the engagement by the engaging mechanism.
Claims4
A vehicle driving control device for a vehicle, the vehicle including:
- an engine and an electric motor a as power sources;
- a differential mechanism whose rotary elements including three rotary elements connected to the engine, the electric motor and a driving shaft, respectively, and performing a differential operation to each another;
- a rotary engagement element rotating integrally with a rotary element other than the rotary element connected to the engine and the rotary element connected to the driving shaft;
- a fixed engagement element fixed so as to be unable to rotate;
- a meshing engaging mechanism selectively fixing the rotary element rotating integrally with the rotary engagement element to be unable to rotate by engaging the rotary engagement element with the fixed engagement element or releasing the engagement of the rotary engagement element with the fixed engagement element;
- and an electric motor driving device driving the electric motor, the vehicle driving control device comprising:
- a control unit configured to stop operation of the electric motor driving device at a time the rotary element is fixed to be unable to rotate, and to recover the operation of the electric motor driving device at a time a predetermined condition based on a parameter relating to a driving of the vehicle is satisfied before releasing the engagement by the engaging mechanism.
