Turn signal flasher-based safety warning device and control method

Abstract

A turn signal flasher-based safety warning device comprises a flash controller, and the flash controller comprises a power source unit, a smart control unit, a signal input unit, a flash frequency control unit and a turn light control unit; the smart control unit outputs a level signal to the flash frequency control unit and the turn light control unit according to a signal transmitted by the input unit, thus controlling a left turn light or a right turn light or both the left and right turn lights to flash, or directly turning on the left turn light or the right turn light; a control method of the device comprises: control of one turn light to flash and the other to emit light nonstop, control of hazard warning lights and turn priority, and automated control of hazard warning lights in emergency braking. The device is simple in structure and low in manufacture cost, can enable the turn lights to act as hazard warning lights, can enable the turn light on one side to flash and the turn light on the other side to emit light nonstop, can give an alarm in case of vehicle crash or emergency braking, allows easy switching of a turning state and a warning state, and is simple to operate and high in safety.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a safety warning device based on a turning flash light. Background technique [0002] The turning flash of a car generally has two functions: 1. As a turn signal light, when the vehicle turns left (or right), the flashing light on the left (or right side) of the vehicle flashes to warn others of the vehicle's steering intention; at this time, the driver can also judge the front and rear according to the different frequencies of the flashing light on the left (or right side) Whether the turn signal is normal (the national standard stipulates two flashing frequencies, if the flashing frequency is faster, it will prompt that the turn signal on this side is abnormal: the front light or the rear light is faulty); 2. As a hazard warning light, the flashing lights on both sides of the vehicle flash synchronously at the same standard frequency to warn other vehicles to avoid. [0003] Althou...

AI Technical Summary

Problems solved by technology

[0004] 1. When used as the first function, when encountering a large intersection where there is no traffic signal light or no lane marking on the road surface, where you can turn and turn around, the parallel car B that is on the opposite side of A car cannot see A Car turn signals, if car B also wants to turn in the same direction, but car B has no way of knowing whether car A wants to go straight or turn. For the needs of civilized and safe driving, car B can only slow down or even stop and wait for car A Go forward until you see the turning posture of car A or the turn signal light, then car B dares to drive forward and turn, so that the traffic efficiency of car B and the vehicles directly behind will be greatly reduced; if car A is still closely following the vehicle, Then car B is likely to turn impatiently and forcibly, which will easily cause congestion at the intersection and cause traffic accidents;

[0005] 2. When used as the second function, the turn signal switch will be invalid, that is, when the vehicle needs to use the turn signal when changing lanes or turning, even if the driver turns on the turn signal switch, there is no turn signal indication, and it still maintains the flashing lights on both sides of the vehicle In the same flashing alarm state, other people or vehicles will not be able to know their steering intention through their turn signals and prepare to avoid them in advance, which will easily lead to traffic accidents; the correct operation should be to release the danger alarm switch first, and then turn on the steering switch. After changing lanes or turning and turning off the steering switch, turn on the danger alarm switch; but the actual situation is often that the driver would rather change lanes or turn with the double flashing warning lights in violation of regulations than do these cumbersome operations, especially when the vehicle When driving in rainy and foggy days, it is usually necessary to turn on the double-flashing warning light (one of the requirements of road traffic safety regulations), but due to low visibility, slippery roads and high speed driving, the driver is already highly nervous. Completing the above cumbersome operations will make the driver more nervous and cause traffic accidents more easily;

[0006] 3. When the vehicle has a high-speed collision accident or emergency braking to stop, in order to avoid being collided by other vehicles, it is a safe way to turn on the double flashing warning lights to warn other vehicles. Coma, or being unable to move, or frightened and disoriented, etc., often cannot turn on the double flashing alarm switch, causing greater losses and injuries

[0008] (1) The situation of driving brakes is frequent, and if the double flashing alarm is triggered too much, it will become disturbing. If the double flashing alarm is also turned on during normal braking, it will frequently interfere with other vehicles and pedestrians, thinking that the car has an accident. Changing lanes to avoid, on the contrary, may easily lead to traffic jams or traffic accidents;

[0009] (2) The maintenance of the double-flashing alarm state is unreasonable. As long as the brake pedal is not pressed, the state will be exited. When the vehicle collides with high-speed or emergency braking stops, and the driver is injured or frightened and his hands and feet are inflexible, he will not be able to rely on it. Keep your foot on the brake pedal to keep the double flash alert on when you need it the most
