The invention discloses an illegal vehicle capturing control system and method based on the car networking and belongs to the field of intelligent transportation system vehicle supervision. In the car networking environment, when a control center monitors that an illegal vehicle passes, an oil-off instruction is sent to an illegal vehicle vehicle-mounted unit immediately through a wireless communication module, and the illegal vehicle is marked as a target vehicle; after the target vehicle receives the oil-off instruction, the target vehicle automatically starts a parking path inducing mode to select a roadside parking site. The illegal vehicle can be controlled remotely to automatically park, and the law enforcement efficiency is improved; through the parking path induction, it is ensured that under the condition of not affecting the traffic order, the illegal vehicle safely and stably parks at the appointed position; information interaction between vehicles is achieved through a wireless short-distance communication technology, a multi-vehicle synergetic self-organizing network is formed, the advantages that the networking time is short and the communication delay is small are achieved, and the requirements for the vehicle network in the rapid moving environment of the vehicle are met.
