1. A hybrid vehicle control system comprising:

  • an engine;

    a motor/generator;

    a first clutch arranged to change a torque transfer capacity between the engine and the motor/generator;

    a second clutch arranged to change a torque transfer capacity between the motor/generator and at least one drive wheel; and

    a controller configured to selectively control the first and second clutches to switch between an electric drive mode in which the engine is stopped, the first clutch is released and the second clutch is engaged and a hybrid drive mode in which both of the first and second clutches are engaged, the controller being further configured to determine whether a power train braking force from a power train of a vehicle that drives the drive wheel is sufficient to achieve a target braking force, and the controller being further configured to operate a wheel brake to apply a wheel braking force against a wheel of the vehicle to maintain the target braking force when an accelerator pedal depressing amount is detected as being substantially zero and when the power train braking force is not sufficient to achieve the target braking force.
