Target car system based on automatic driving

The embodiment of the invention relates to a target vehicle system based on automatic driving. The target vehicle system comprises an automatic driving controller, a drive-by-wire chassis, a switch, a first vision module, a laser radar and a millimeter wave radar, the drive-by-wire chassis, the switch, the first vision module and the millimeter wave radar are respectively connected with the automatic driving controller; the laser radar is connected with the switch; the automatic driving controller receives first environment sensing data collected by the laser radar, second environment sensing data collected by the first visual module and third environment sensing data collected by the millimeter wave radar, which are sent by the switch, and performs fusion processing on the first environment sensing data, the second environment sensing data and the third environment sensing data, and obstacle information is generated; the obstacle information comprises distance information between other target vehicles in the
