Target identification method and device

The embodiment of the invention provides a target identification method and device. When a vehicle steers, the driving curvature radius of the vehicle is determined according to the distance between afront wheel and a rear wheel of the vehicle is the distance between the front wheel and the rear wheel of the vehicle. The driving curvature radius of the vehicle and the driving speed of the vehicleare calculated and a target identification range is determined. Furthermore, a target is identified according to the target identification range, such as environment and vehicle information. The target selection mode is changed to efficiently select the most proper target. The invention is suitable for ACC, AEB systems loaded on all vehicles. The problem that the system mistakenly identifies the target or misses identification to send out error control under the curve condition is solved during curves, the system performance is greatly optimized under the condition that the cost is not increased, and the invention is
