Abstract

The invention discloses an automatic turning light switching-on system of a vehicle, belonging to the field of early warning for safe driving of automobiles. The automatic turning light switching-on system comprises a signal acquisition module, a single chip microcomputer and an execution module. The input end of the single chip microcomputer is connected with the signal acquisition module, and the output end of the single chip microcomputer is connected with the execution module. The signal acquisition module is used for acquiring vehicle speed signal, steering wheel angle signal, steering wheel speed signal, turning light switch signal and lane line image information of the vehicle. Single-chip microcomputer is used to synthetically process the signals acquired by the signal acquisitionmodule and output the control signal to the execution module. The executing module controls whether the turn signal needs to be turned on according to the signal output from the single chip microcomputer. The invention has the characteristics of simple operation, low cost and the like. The invention utilizes the hardware resources provided on the existing automobile to judge the driving intentionof the driver through the creative design. If the driver is judged to change lanes without turning on the turn signal lamp, the corresponding turn signal lamp is automatically turned on to achieve thepurpose of prompting the rear vehicle to avoid concession.

Description

technical field [0001] The invention relates to the field of early warning for safe driving of automobiles, in particular to an automatic turn-on system for vehicle turn signals. Background technique [0002] The traffic control department proposes: If a vehicle needs to change lanes while driving, it should first observe whether there is an oncoming vehicle at the rear, and then change lanes only if it does not affect the normal driving of the vehicle behind. Changing lanes needs to turn on the turn signal in advance, so that the vehicles behind know the intention of the vehicle in front, and allow the vehicles behind to have sufficient preparation time. However, in reality, the driver often forgets to turn on the turn signal when changing lanes. According to investigations, many traffic accidents are caused by drivers forgetting to turn on the turn signals. [0003] Therefore, there is an urgent need in the market for a device that can predict in advance whether the driv...
