Though the braking performance test of drum brakes I verified the brake pressure and brake deceleration the accuracy of the relational model, and demonstrated the brake failure warning program.
Thus a method is proposed to extract a corresponding equivalent dual-trapezoids curve (EDTC) from the car body deceleration curve in full scale frontal crash test to be used in sled test.
