Abstract: A cooperative control method is disclosed. The cooperative control method includes: acquiring a target heating power, a target driving power, and a target charging and discharging power; acquiring a first heating power of a motor coil according to the target charging and discharging power; acquiring a second heating power of the motor coil according to the target driving power; adjusting a first quadrature axis current and a first direct axis current to a target quadrature axis current and a target direct axis current to cause the difference between the sum of the first heating power and the second heating power and the target heating power to be within the preset range; and acquiring a sampling current value on each phase coil and a motor rotor position, and calculating a duty cycle of each phase bridge arm in a reversible PWM rectifier according to the above information.
