The invention provides a vehicle damping continuously-adjustable vibration reduction control method and system and a vehicle, an IMU is used for replacing four sprung acceleration sensors, six-direction inertial signals, measured by the IMU, of a mounting position are converted into Z-direction acceleration signals of points on four vibration absorbers by utilizing a dynamic explicit integration method based on vector calculation, and the Z-direction acceleration signals are converted into Z-direction acceleration signals of points on the four vibration absorbers. According to the invention, the four shock absorbers and the telescopic speed of the four shock absorbers detected by the four unsprung acceleration/angle sensors are introduced into a Mixed-SH-ADD algorithm for calculation, and the control current of the solenoid valves of the four shock absorbers is output, so that the problems that the existing CDC sensors are many and high in cost and the existing sensing conversion method is poor in precision and few in applicable working conditions can be solved.
