Active safety system for detecting vehicle distance, and control method

Abstract

The invention provides an active safety system for detecting a vehicle distance, and a control method, and belongs to the technical field of automotive electronics. The active safety system solves the problems that in the prior art, the detection of the vehicle distance is not perfect enough, and drivers cannot be effectively warned. The active safety system comprises a control module, a detection module, a display module, a warning module, an ignition switch connected with the control module, and a rotating speed sensor connected with the control module, wherein the detection module detects surrounding barriers and transmits a detection result to the control module; the control module receives and processes the detection result so as to determine the states of the barriers, and the detection result is displayed through the display module; the warning module is controlled to send out a warning when a collision risk occurs. The control method comprises the following steps: the step I, starting the active safety system; step II, detecting the distance between a barrier and the vehicle; step III, judging whether the barrier influences the safety of the vehicle; and step IV, sending out a warning from the warning module. Through the adoption of the active safety system and the control method, the safety distance between two vehicles can be judged, and drivers can be warned and provided with safety prompt.

Description

technical field [0001] The invention belongs to the technical field of automobile electronics, and relates to a vehicle distance detection active safety system and a control method. Background technique [0002] When the vehicle is driving on the road, the driver begins to constantly judge the safe distance between the surrounding vehicles and his own vehicle. However, due to the complexity of the road conditions and lack of driving experience, there are certain potential safety hazards in the judgment, for example, if the vehicle is too far away from the vehicle in front. Tight, in an emergency state, it is too late to brake and cause a rear-end collision; this car brakes the car, and the rear car rear-ends. In a similar state, the first is a waste of time and money, and the second is a potential safety hazard for life. In the existing technology, it has been able to realize the active braking function when an object is found in front of the vehicle. The feature of this fun...

Problems solved by technology

[0004] The above-mentioned patent can solve the problem of judgment and early warning of vehicles coming from behind when the vehicle changes lanes, and improves the safety of the vehicle driving process to a certain extent. However, the above-mentioned scheme cannot predict the driving trend of the vehicle behind, and the alarm effect is not good enough. security is not high enough
