A construction machine includes: a swing structure (20); hydraulic and electric motors (25) mechanically coupled to each other; a hydraulic pump (41) that supplies hydraulic fluid to the hydraulic motor; swing control lever (72) that instructs the swing structure to make a swing motion; and a control device (80) that controls at least either a delivery flow rate of the hydraulic pump or an output torque of the electric motor in such a manner that meter-out and meter-in pressures of the hydraulic motor that is run together with the electric motor approach each other when the demanded torque necessary for the swing motion of the swing structure instructed by the swing control lever can be produced by the electric motor alone.

A control method and apparatus are provided. The method is applied to a vehicle including a first motor and a second motor. The method includes: obtaining reference information, where the reference information includes a driving mode of the vehicle; and controlling, based on the driving mode of the vehicle, the second motor to be turned on or turned off. The motor of the vehicle can be flexibly controlled in different driving modes. This helps improve cost-effectiveness and driving stability of the vehicle.
