7. The method for the synchronous rhythm of the full active suspension system matched with the vehicle-mounted entertainment system along with the music according to claim 1, wherein the step e is specifically as follows: the power of an actuator of the suspension is in the same proportion with the weighted value of the input power of the main pronunciation unit during synchronous rhythm, and the proportionality coefficient is k.
8. The method of claim 7, wherein the suspension actuator power remains at a minimum power input when the bass unit power weighting is highest such that the bass unit input power weighting is less than the threshold C1, and no longer varies proportionally with the sonification unit input power; when the weighted value of the input power of the bass unit is greater than the threshold value D1, the power of the suspension actuator keeps the highest power input and does not change in proportion to the input power of the vocal unit.
9. The method of claim 7, wherein the power weighting of the midrange unit is the highest, such that when the weighting of the input power of the midrange unit is less than the threshold C2, the power of the suspension actuator remains the lowest power input and does not change proportionally with the input power of the articulation unit; when the weighted value of the input power of the mediant unit is larger than the threshold value D2, the power of the suspension actuator keeps the highest power input and does not change in proportion to the input power of the pronunciation unit.
10. The method of claim 7, wherein the full active suspension system is synchronized with the vehicle entertainment system to beat with music, and the method comprises the following steps: when the weighted value of the power of the high-pitch unit is the highest, and the weighted value of the input power of the high-pitch unit is smaller than a threshold value C3, the power of the suspension actuator keeps the lowest power input and does not change in the same proportion with the input power of the pronunciation unit; when the weighted value of the input power of the treble unit is greater than the threshold D3, the suspension actuator power remains at the highest power input and no longer varies proportionally with the sound unit input power.
