Title:
POWER SYSTEM CONTROL METHOD FOR FOUR-WHEEL-DRIVE ALL-ELECTRIC VEHICLE, AND POWER SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/082854
Kind Code:
A1
Abstract:
A power system control method for a four-wheel-drive all-electric vehicle, and a power system. The method comprises: acquiring a first required torque M11 for driving a vehicle to travel under a driving working condition, acquiring the sum of the maximum output torque of a first motor (1) and the maximum output torque of a second motor (2) as M21, and comparing magnitudes of M11 and M21; in response to determining that M11 > M21, controlling a clutch (5) to engage, and the first motor (1), the second motor (2) and a third motor (3) to simultaneously output a torque, the sum of the output torques being M11; and in response to determining that M11 ≤ M21, controlling the clutch (5) to disengage, and the first motor (1) and the second motor (2) to output a torque, the sum of the output torques being equal to M11, thereby reasonably allocating output torque of the multiple motors.
