This invention provides a vehicle control device capable of suppressing vibration and impact when a parking lock mechanism is released while the drive shaft is in a torsional state. It comprises: a drive shaft, one end of which is connected to a wheel; a motor capable of transmitting torque to the drive shaft; and a parking lock mechanism capable of selectively switching between: a locked state that prevents rotation of a predetermined rotating component between the motor and the drive shaft, and a released state that allows rotation of the predetermined rotating component. When it is predicted that the parking lock mechanism will switch from the locked state to the released state, the device begins to output a torque from the motor that is counteracting to and less than or equal to the estimated torsional torque of the drive shaft (step S4), and stops outputting torque from the motor at the point when the motor begins to rotate (step S1).

The invention relates to the technical field of new energy power generation, and discloses a new energy active support control system and method, and the system mainly comprises a new energy power generation system, an inverter module, a current and voltage collection module, a power calculation module, a transient state quantity adjustment module, a virtual rotational inertia module, a virtual excitation adjustment module, and a control signal module. Transient stable support is provided for a new energy power generation system by simulating rotational inertia and excitation adjustment of a synchronous generator, and output power is adjusted in real time through closed-loop control, so that stable operation of a power grid is ensured. According to the method, active support of a new energy power generation system and stable control of a power grid are realized through the steps of real-time data acquisition and processing, power adjustment and closed-loop control, transient support and fault response, control signal generation, inverter adjustment, continuous monitoring, steady-state operation and the like.
