1. A method for monitoring tyre pressure variation of automobile tyre, comprising steps of:
- (1) obtaining rotation speeds of individual automobile tyres, and creating rotation speed reference values Vr for comparison and judgment based on the obtained rotation speeds;
(2) obtaining current rotation speeds of individual automobile tyres, and comparing the values corresponding to the obtained current rotation speeds of individual tyres with the rotation speed reference values Vr of individual tyres;
(3) judging the compared result of step (2), and raising an alarm if the compared result is beyond a preset value;
(4) turning to step (2).
