The embodiment of the invention relates to the technical field of intelligent driving, and particularly discloses a target validity judgment method and system in an intelligent driving process. According to the embodiment of the invention, target-related motion parameters identified by a plurality of perception sensors are acquired, and self-vehicle motion parameters are acquired; relative transverse and longitudinal distance parameters of the target and the vehicle are calculated; according to the confidence deviation value, target validity is judged, and target validity flag bit information is generated when the target is valid; and performing transverse and longitudinal control according to the target validity flag bit information and the target related motion parameters. The problems that the AEB function fails or the ACC function cannot be normally used due to inaccurate target validity judgment and target recognition omission of the intelligent driving system caused by previous mounting difference and starting time and delay time difference of the sensor can be avoided, and the problems that the function use feeling of a driver is poor due to insufficient redundancy of sensor recognition, and the driver experience is poor can be avoided. And more seriously, potential safety hazards are brought to the driver.
本发明实施例涉及智能驾驶技术领域,具体公开了一种智能驾驶过程中目标有效性判断方法及系统。本发明实施例通过获取多个感知传感器识别的目标相关运动参数,并获取自车运动参数;计算目标与自车的相对横纵向距离参数;依据置信偏差值,判断目标有效性,在目标有效时,生成目标有效性标志位信息;按照目标有效性标志位信息和目标相关运动参数,进行横纵向控制。能够避免因传感器之前的安装差异、启动时间和延迟时间差异,而导致的目标有效性判断不准确、智能驾驶系统漏识别目标,进而使得AEB功能失效或ACC功能不能正常使用的问题,能够避免传感器识别上的冗余不足,带给驾驶员功能使用感差,更严重的是带给驾驶员人身安全隐患的问题。
