The invention discloses an axle load and vehicle speed dynamic sensing device and a measuring method. The axle load and vehicle speed dynamic sensing device comprises a base, a plurality of piezoelectric ceramics and a pressing plate. A rectangular groove is formed in the top surface of the base, a plurality of piezoelectric ceramics arrays are arranged in the rectangular groove of the base, the top end and the bottom end of each piezoelectric ceramic are respectively connected with an electrode, each electrode is connected with a wire, the pressing plate is arranged at the top of the piezoelectric ceramics, the bottom surface of the pressing plate is larger than the array area of the piezoelectric ceramics, and the top surface of the pressing plate is arranged on a road surface. The corresponding data of the vehicle can be accurately acquired, and the axle weight and the speed of the vehicle can be sensed simultaneously.
