Abstract
A determination method and apparatus for permitting deceleration regeneration or charge of a hybrid vehicle, by which erroneous determination relating to the clutch operation can be prevented. The method includes a first determination step of detecting clutch operation performed by a driver and determining a connection state of the clutch; a second determination step of determining a connection state of the clutch based on a correspondence relationship between vehicle speed and engine speed; and a permission determining step of permitting the deceleration regeneration or charge by the motor when it is determined that the clutch is connected both in the first and second determination steps.
