AI Technical Summary
Technical Problem
When a rotary transformer malfunctions, the existing technology has low motor control efficiency, which can easily lead to motor damage and personal injury.
Method used
By detecting the state of the rotary transformer, vehicle speed information is obtained, the motor speed information is determined, and when the speed exceeds or falls below the threshold, the motor is controlled to enter a short circuit or open circuit state, forming a closed loop or disconnecting from the vehicle's power system.
Benefits of technology
It enables precise control of the motor when the rotary transformer malfunctions, avoids speed estimation errors, improves control efficiency, and ensures the safety of the motor and the driver/passengers.

Abstract
本发明公开了一种车辆中电机的控制方法、装置和车辆。其中，该方法包括：检测车辆中至少一旋转变压器的状态；响应于至少一旋转变压器的状态为异常状态，获取车辆的速度信息；基于速度信息，确定至少一电机的转速信息；响应于转速信息大于转速阈值，确定至少一电机进入短路状态，并基于短路状态对应的控制指令，控制至少一电机形成闭合回路；或者，响应于转速信息小于等于转速阈值，确定至少一电机进入断路状态，并基于断路状态对应的控制指令，控制至少一电机与车辆中的整车动力系统断开。本发明解决了当旋转变压器异常时对电机进行控制的效率低的技术问题。
