Abstract: A control apparatus sets an upper limit guard value to a base value when the MG provides torque assist to thereby limit the command value for the MG. Then, the control apparatus limits the command value for the MG using the upper limit guard value to limit the output of the MG. If an accelerator opening or the change rate thereof is not less than a predetermined value, the control apparatus corrects the upper limit guard value. The correction is made such that the larger accelerator opening or a larger change rate thereof causes the upper limit guard value to be larger to accomplish higher output. Similarly, if the SOC of the battery is not less than a predetermined value, the control apparatus corrects the upper limit guard value. If the engine speed is not less than a predetermined value, the control apparatus corrects the upper limit guard value.

The restart control device has a restart-condition determining portion which determines whether a restart condition for restarting the internal combustion engine is established while the vehicle is coasting; a push-start portion which starts the internal combustion engine by a push-start; a start-up portion which starts the internal combustion engine by use of an electric motor; and a doubly start-up portion which tries to start the internal combustion engine by one of the push-start portion and the start-up portion when the restart-condition determining portion determines that the restart condition is established. The doubly start-up portion tries to start the internal combustion engine by another one of the push-up portion and the start-up portion when the internal combustion engine has not been started.

Abstract: A vehicle control device turns off a clutch to put a vehicle into an inertia operation state in response to a predetermined executing condition being met, and turns on the clutch to terminate the inertia operation state in response to a predetermined terminating condition being met during the inertia operation. The vehicle control device includes a deceleration degree calculating device, a determination device, and an operation control device. The deceleration degree calculating device calculates an actual deceleration degree. The determination device determines whether the actual deceleration degree is greater than a threshold value defined on the basis of a deceleration degree of the vehicle in an accelerator-off and clutch-on state. The operation control device terminates or maintains the inertia operation depending on a condition of the actual deceleration degree.
