Abstract:
A method for controlling a power system of a four-wheel-drive all-electric automobile, and a power system. The method for controlling a power system of a four-wheel-drive all-electric automobile comprises: when in a traveling operating state, acquiring a first required torque M11 used to drive a vehicle to travel, acquiring a maximum output torque M12 of a first motor (1), a sum of the maximum output torque of the first motor (1) and a maximum output torque of a second motor (2) being M13, and comparing M11, M12 and M13. In response to determining that M11 ≤ M12, a first clutch (51) is disengaged, a second clutch (52) is disengaged, and the first motor (1) outputs a torque; and in response to determining that M13 ≥ M11 > M12, the first clutch (51) is engaged, the second clutch (52) is disengaged, and the first motor (1), the second motor (2), and the third motor (3) simultaneously output torque.
