Description

[Technical Field]

[0001] The present invention relates to the field of automotive control technology, and more particularly to automotive side mirror turn signal control systems. [Background technology]

[0002] With the development of automobiles, warnings, especially side warnings, have always been an important function while driving. Although existing vehicles rely on headlights and taillights to provide safety warnings and identification while driving, turning, and reversing, in dimly lit environments, the center of the vehicle is an area that is difficult for pedestrians to see. However, due to limitations in complex driving environments, front and rear lighting alone is not sufficient.

[0003] At present, side mirror turn signals are not yet fully widespread, and vehicles without turn signal functions on the side mirrors need turn signals with such high warning and recognition levels. For vehicles with turn signals on the side mirrors, the lamp effect of the turn signals originally installed on the vehicles is uniform, the illumination brightness is low, and the warning effect is greatly reduced. Side mirror turn signals need better warning and recognition lights to better ensure driving safety.

[0004] The original vehicle's turn signals only have one light display effect: flashing or continuous. The mode is fixed and cannot be switched. If the car owner needs to add, change the light effect, or restore the mirror after modification, they must disassemble the side mirror again. This is not only tedious but can also damage the mirror. If the car owner is not familiar with how to operate it, they will have to go to a repair shop to have it replaced, which will cost more time and money.

[0005] Chinese Patent Application No.: 201310372936.2, Filing Date: August 23, 2013, Publication Date: November 27, 2013, Patent Title: Side Mirror Turn Signal Constant Current Drive Control System. This invention provides a side mirror turn signal constant current drive control system including an input module, a step-down module, a current stabilizing module, and a plurality of LED lights. The voltage input by the input module is output to the plurality of LED lights via the step-down module, turning on the plurality of LED lights. The current stabilizing module minimizes changes in current flowing through the plurality of LED lights when the input voltage fluctuates. The plurality of LED lights are configured to be connected in series and parallel. This invention realizes constant current drive for automobile side mirror turn signals using a simple circuit, so that the brightness of the automobile side mirror does not change due to changes in input voltage. This invention fully utilizes the operating characteristics of currently common diodes and triodes and combines the creativity of both, achieving the constant current control effect that can be achieved using conventional integrated chips with just two elements.

The MCU control module 200 controls the signal interface circuit 700 through the signal detection circuit 600.

[0024] Preferably, the MCU control module 200 is a model number TL16C554 chip.

[0025] In this embodiment, the MCU control module 200 can control the first driving circuit 400 through the switching control circuit 300 , and of course, the MCU control module 200 can also control the second driving circuit 410 through the switching control circuit 300 .

[0026] In this embodiment, the present invention can include a plurality of driving circuits and a plurality of LED light-emitting modules, and more preferably, the at least two driving circuits include three driving circuits, and the LED light-emitting module includes three LED light-emitting modules.

[0027] The three driving circuits include a first driving circuit 400, a second driving circuit 410, and a third driving circuit 420, and the three LED light-emitting modules include a first LED light-emitting module 500, a second LED light-emitting module 510, and a third LED light-emitting module 520; In this embodiment, the MCU control module 200 may use the switching control circuit 300 to control the first driving circuit 400, the second driving circuit 410, or the third driving circuit 420, respectively. Of course, the MCU control module 200 may simultaneously control the first driving circuit 400 and the second driving circuit 410, and the switching control circuit 300 may control the third driving circuit 420. The first driving circuit 400, the second driving circuit 410, and the third driving circuit 420 control the first LED light-emitting module 500, the second LED light-emitting module 510, and the third light-emitting module 520, respectively.

[0028] In this embodiment, the MCU control module 200 preferably includes a memory 210 for storing and recording information that the MCU control module 200 processes.

[0029] In this embodiment, the power management module 100 preferably includes a charging circuit 110 .

[0030] In this embodiment, more preferably, the power management module 100 may further include a discharge circuit, which can control the color change of the vehicle lamp to improve the warning effect of the vehicle lamp.

[0031] The charging circuit 110 charges the power management module 100, ensuring the continuous operation of the present invention and greatly improving the working efficiency.

[0032] In this embodiment, preferably, the turn indicator control system of the present invention further includes a vehicle signal terminal 800, and the signal detection circuit 600 detects signal information transmitted from the vehicle signal terminal 800 through the signal interface circuit 700. In this embodiment, more preferably, the vehicle signal terminal 800 includes vehicle lamp signal 810 information or bus signal 820 information.

[0033] In this embodiment, more preferably, the vehicle signal terminal 800 further includes a part / total length signal 830 .

[0034] In this embodiment, the turn indicator provides an operating signal to the MCU control module 200 via a vehicle lamp signal 810 or a bus signal 820. After the vehicle lamp signal disappears, the power management module 100 supplies electricity to the MCU control module 200 within a unit time to ensure that the MCU control module 200 does not turn off. The MCU control module 200 records the number of times of the vehicle lamp bus signal 820 through the memory 210 and triggers the switching of the lamp dynamic effect according to the number of times.

[0035] Referring to FIG. 6, in this figure, the reference numeral 910 represents the operating period and the reference numeral 920 represents the switching period. In this embodiment, the vehicle signal terminal 800 can supply power to the power management module 100, and the power management module 100 can supply the MCU control module 200 with the amount of power required for normal operation without the input of a vehicle signal for T seconds; The MCU control module 200 uses the signal detection circuit 600 to determine whether there is currently a vehicle signal input. If there is a vehicle signal input, it controls the driving circuit to drive the LED light-emitting module to produce a lamp effect, and accumulates the number M of vehicle signal inputs.

[0036] In this invention, the time period from the first vehicle signal to the disappearance of the last vehicle signal exceeds T seconds (maximum electrical energy storage maintenance time) is defined as one operating cycle. At the start of the second operating cycle, the control chip module reads the number of vehicle signal inputs M in the previous operating cycle, and if the number M is equal to S, accumulates the number of operating cycles P; otherwise, it sets the number of operating cycles P to 0. Then, it records the number of operating cycles P in a power-down storable memory (including, but not limited to, EEPROM, FLASH (registered trademark), etc.). If the number of operating cycles P is equal to Q, it performs a ramp effect mode switching operation. The entire period that satisfies the switching condition is called a switching period, and a switching period consists of several operating cycles that satisfy the condition.

[0037] In this embodiment, if the vehicle signal input count M is 2, the time T is 2 seconds, and the operation cycle is 5, the dynamic effect mode switching procedure can be realized by the following operations (including but not limited to the following):

[0038] Method one Step 1: Press the unlock button on your car's smart key once, and you will receive two signal inputs. Step 2: Press the unlock button the first time, wait less than two seconds, then press the unlock button again a second time, then pause and wait three seconds. Step 3: Repeat step 2 six times, switch the dynamic effect mode from the sixth time, and you can see the new lamp dynamic effect.

[0039] Method 2 Step 1: Press the hazard switch inside the car, and control the number of signal inputs by the hazard switch, so that the number of signal inputs each time is kept at two. Step 2: Press the hazard switch, wait for the hazard lights to flash twice, press the hazard switch again, then pause and wait for 3 seconds. Step 3: Repeat step 2 six times, switch the dynamic effect mode from the sixth time, and you can see the new lamp dynamic effect.

[0040] The purpose of the present invention is to solve the safety problems caused by the absence of warning lights or poor warning effect in automobile side mirror turn signals, and to improve the overall aesthetic appearance and scientific and technological safety of the vehicle. The present invention can be installed on the outside of an automobile side mirror, and can provide different dynamic effects when the vehicle is moving, turning, or reversing, and these dynamic effects can be set by the user.

[0041] The above are only preferred embodiments of the present invention, and do not limit the protection scope of the invention.
