Motors play a core role in autonomous vehicles, being key to advancing vehicle performance, safety, and ensuring a smooth driving experience. They are primarily used in the power system to provide efficient and rapid propulsion; in vehicle control, they achieve precise driving without human intervention through accurate control of acceleration, deceleration, and steering; they enhance auxiliary systems such as automatic door controls, seat adjustments, and air conditioning controls, improving passenger comfort; they adjust the angle and direction of sensors and external vehicle devices, optimizing the perception of the surrounding environment; and in emergency situations, they react quickly through automatic braking and vehicle posture adjustments to ensure safety. With the continuous advancement of motor technology, its applications in autonomous vehicles are set to expand and deepen further.
