The invention discloses a vehicle lateral collision prevention method, device and system. The method includes: receiving a vehicle side collision prevention start signal; when the vehicle side collision prevention start signal is received, judging whether other vehicles are in a detection range or not; when other vehicles are in the detection range, measuring relative speed, relative distance and relative angle of the vehicle relative to other vehicles; calculating collision time of the vehicle with other vehicles according to the relative speed, relative distance and relative angle, and performing collision prevention operations according to the calculated collision time. The vehicle lateral collision prevention method, device and system has the advantages that safety accidents can be prevented effectively, driving the vehicles is safer and more intelligent, and practical value is high.
