Intelligent automobile lane change warning system and warning method thereof

Abstract

The invention relates to the field of automobile safe driving, and discloses an intelligent automobile lane change warning system and a warning method thereof. The warning system comprises a front detector, a rear detector, a speed sensor, an angle sensor, a microprocessor, a display screen and an alarm, wherein the front detector and rear detector are used for collecting the driving condition information of a target vehicle; the speed sensor is used for collecting the speed of the vehicle; the angle sensor is used for collecting the turning angle of a steering wheel of the vehicle; the microprocessor is used for processing the driving condition information of the target vehicle and controlling to display the warning information; the display screen is used for displaying the speeds of the vehicle and the target vehicle and the related warning information; and the alarm is used for generating a danger prompt tone. The warning method mainly comprises the following steps of: setting the minimum time headway data and TTC warning time range in the microprocessor; collecting the information of the front and rear vehicles by the detectors; calculating the real-time collision time; displaying the lane change warning information; and generating a lane change forbidding prompt tone. Through the warning system and warning method, accurate lane change information can be provided for the drivers in time so as to reduce traffic accidents.

Description

technical field [0001] The invention relates to the field of safe driving of vehicles, in particular to an intelligent vehicle lane change early warning system and an early warning method thereof. Background technique [0002] On the expressway, lane changing and overtaking are common driver behaviors. It is a comprehensive behavior process in which the driver adjusts and completes his own driving target strategy according to the surrounding environment information such as the speed and distance of the surrounding vehicles. In such a complex process, the driver is likely to make improper judgments on the feasibility of safe lane changing and overtaking, which puts the moving vehicle in a potential collision. At present, in the process of changing lanes, most drivers perform lane changing behavior through vision and experience. Sometimes the driver has already started to change lanes, but at this time the distance between vehicles in the target lane is not conducive to changi...

Problems solved by technology

However, most of today’s technical solutions have a major inherent defect: once in bad weather such as rainy days, snowy days, foggy days, and at night, the data collected by the camera will be greatly deviated due to the influence of light. Even in the case of extremely bad weather, no data can be collected, which will bring serious misleading to the driver, bury hidden dangers for safe driving, and fail to achieve the goal of truly realizing lane change assistance and safe driving
