Problems solved by technology

[0003] However, since the lane-changing warning device judges the lane-changing condition by calculating the parameter TTC, and the threshold value of the parameter TTC is different under different relative speeds and relative distances, there are cases where the lane-changing warning device falsely reports
When the driver in the process of changing lanes suddenly finds that he does not have the conditions for changing lanes and gives up changing lanes, the warning device for lane changing has been activated and will continue to alarm, which will cause driving interference to the driver of the own vehicle, and at the same time make the rear driver misjudgment
Therefore, the occurrence of false alarms by the lane change warning device will bring great unsafe factors to the driving environment

Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings.

[0029] see figure 1 , a device for reducing the false alarm rate of lane change warning includes a vehicle speed sensor 1 and a lane line sensor 2 fixed on the front of the vehicle, the vehicle speed sensor 1 and the lane line sensor 2 are connected to a central processing chip 3, and the central processing chip 3 is connected to the turn signal 4 and an alarm mechanism 5; the vehicle speed sensor 1 is used to collect the current speed of the vehicle; the lane line sensor 2 is used to collect the lane lines on both sides of the vehicle;

[0030] The central processing chip 3 is used to collect the information of the turn signal 4, the information of the vehicle speed sensor 1, and the information of the lane line sensor 2, and compare the information of the turn signal 4, the information of the vehicle speed sensor 1, and the information of the lane line sensor 2 with ...

Abstract

The invention discloses a device for decreasing the lane changing early warning false alarm rate and a method of the device. Turn light information, vehicle speed sensor information and lane line sensor information are collected through a central processing chip and are compared with the threshold value, and finally an alarm mechanism is controlled. According to the device for decreasing the lane changing early warning false alarm rate and the method of the device, the driving condition of a driver is compared with the threshold value in a system, whether the driver changes a lane or gives up changing the lane or not can be judged automatically, accordingly, the alarm mechanism is controlled automatically, and the situation that the driver of a vehicle is disturbed, and the driver of a rear vehicle misjudges the driving condition is avoided.

Description

technical field [0001] The invention belongs to the field of traffic safety, and in particular relates to a device and method for reducing the false alarm rate of lane-changing early warning. Background technique [0002] When the vehicle changes lanes, the driver must not only pay attention to the road conditions ahead, but also observe the road conditions behind the vehicle through the mirror at all times. This increases the difficulty of vehicle operation and the driver is difficult to give enough attention to the rear vehicle. Moreover, when the driver changes lanes, he mainly observes the movement status of the rear vehicle through the reflector, which makes it difficult to have an accurate judgment on the movement status of the rear vehicle. Along with the development of automobile technology, people have invented many kinds of lane-changing warning devices to come the generation of above-mentioned these situations. [0003] However, since the lane-changing warning d...
