The invention provides a forward anti-collision early-warning method based on a laser radar. The method comprises the following steps of: S1, measuring the distance D between a car and a forward car through the laser radar; S2, reading the speed and accelerated speed of the car through a CAN cable; S3, calculating the safety distance according to a safety distance formula, wherein the safety distance formula is Dw=V2/2(a-f)+V*(T+s), Dbr=V2/2(a-f)+V*Ts, Dw stands for the alarming distance, Dbr stands for the automatically braking distance, V stands for the speed of the car, a stands for the accelerated speed of the car, f stands for the corrected value of the accelerated speed, T stands for the braking time, Ts stands for the automatically braking response time, and s stands for the corrected value of the braking time; as the further improvement of the invention, S4, judging according to the safety distance formula in the step S3, and taking out corresponding measures. The forward anti-collision early-warning method based on the laser radar has the following beneficial effects: car owners are early warned or measures are taken out for the cars according to different early-warning grades, thus the anti-collision effects are achieved, rear-end collisions are effectively reduced, and traffic accidents are reduced.
