Abstract

The invention discloses an alarm method and a parameter real-time adjustment method of a front collision early warning system, and belongs to the technical field of automobiles. The alarm method of the front collision early warning system comprises the following steps: S1, judging whether an obstacle exists in front of a vehicle at present, and if not, not generating an alarm instruction; if yes, executing the step S2; s2, judging whether the judgment parameter E is greater than or equal to 1; if yes, not generating the alarm instruction; if not, executing the step S3; s3, judging whether the judgment parameter E is larger than or equal to the comparison parameter h, and if yes, carrying out first-level alarming; if not, executing the step S4; s4, judging whether the judgment parameter E is larger than or equal to 0 , and if yes, carrying out second-level alarm ; and if not, starting the whole vehicle automatic emergency braking function. Graded alarm can be carried out, and the experience is better.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an alarm method and a real-time parameter adjustment method of a front collision warning system. Background technique [0002] FCW (Forward Collision Warning, Forward Collision Warning) system is an advanced safety assistance system, which judges the potential collision risk by sensing and calculating the distance between the vehicle and the vehicle in front during driving, and issues a warning immediately. [0003] However, in the prior art, several collision distance intervals have the same alarm level, and usually there are about 3 to 4 collision distance intervals, which will lead to different dangerous situations corresponding to the same danger alarm level, and the experience is not good. Contents of the invention [0004] An object of the present invention is to provide an alarm method for a forward collision warning system, which can perform different levels of alar...
