The invention discloses a vehicle flow detection system based on weak magnetic sensors. The vehicle flow detection system employs weak magnetic sensors to detect existence of vehicles and vehicle flow information, the detection precision can be raised, the detection system is free from extreme weather and environments, and misjudgement rate can be lowered greatly. The detection system employs three magnetic sensors formed by two magnetic detection probes integrated on a circuit chip and a single magnetic detection probe, every two of the three magnetic sensors are orthogonal, the magnetic sensor size can be reduced, and convenient burying in pavements of lanes is achieved.
