The invention discloses a vehicle theft prevention method based on driving motor control. In the running process of a vehicle, when a motor is in an electric mode and a motor controller receives an anti-theft alarm signal, the output torque of the motor is controlled to be gradually reduced until the motor reaches a zero-torque state, so that the vehicle stops running. An anti-theft vehicle control strategy is added through the driving motor controller, an anti-theft locking device does not need to be additionally arranged, a driving motor can be controlled to enable the driving motor not to output driving torque, then the vehicle cannot run, the anti-theft purpose is achieved, the situation that the anti-theft function fails due to violent damage to the locking device is avoided, and extra weight and cost of the locking device and occupation of the whole vehicle space are saved.
本发明公开了一种基于驱动电机控制的防盗车方法。它车辆运行过程中,电机处于电动模式,电机控制器接收到防盗报警信号时,控制电机输出扭矩逐步降低直至电机达到零扭矩状态,使车辆停止运行。本发明通过驱动电机控制器增加防盗车控制策略,无需额外增加防盗锁止装置,即可实现通过控制驱动电机,使驱动电机不输出驱动扭矩,进而使车辆无法行驶,以达到防盗目的,避免了暴力破坏锁止装置使防盗功能失效,也省去了锁止装置额外的重量、成本和对整车空间的占用。
