Description

Staged brake light display method and system thereof

The present invention relates to a vehicle light display system, in particular to a staged brake light display method and system thereof.

The performance and driving speed of today's vehicles are increasing day by day. Because of the increased braking stability of vehicles at high speeds, disc brakes have become mainstream, and the brake units of many models also use Antilock Brake System (ABS), Systems such as Vehicle Stability Control (VSC), Traction Control System (TCS) and Electronic Stability Control (ESC) are used together to meet safety requirements.

In one embodiment, the brake unit 1 is a disc brake, but it is not limited thereto. Its operating principle is that when the driver gives the stepping member 11 a displacement, the piston in the brake master cylinder will be pushed, and a brake pressure will be established in the brake oil circuit. Pressure, this pressure is transmitted to the piston of the brake cylinder on the brake caliper through the brake fluid. After the piston of the brake cylinder is under pressure, it will move outward to make the disc clamp the brake disc, so that the disc and the brake disc will Friction to slow down the wheel speed, slowing or stopping the car.

In this embodiment, the sensing unit 2 is a displacement sensor, and the displacement sensor can be a laser displacement gauge or a contact displacement gauge, but it is not limited thereto. As can be seen from the foregoing, the displacement of the pedal member 11 is similar to that of the automobile. The degree of deceleration is positively correlated.

The first lighting area L1 is a ring shape, and the second lighting area The area L2 is a circular area formed by a plurality of cylinders of different sizes, the third lighting area L3 is a ring of hexagonal columns, and the fourth lighting area L4 is a ring of elliptical columns. Shaped areas, but not limited thereto, other geometric shapes can also be used for arrangement to distinguish their lighting areas.

In this embodiment, when the displacement ratio of the operation processing unit 3 is not more than 25%, the judgment result is the first lighting mode; when the displacement ratio is greater than 25% and not more than 50%, the judgment result is the second The second lighting mode; when the displacement ratio is greater than 50% and not more than 75%, the judgment result is the third lighting mode; when the displacement ratio is greater than 75%, the judgment result is the fourth lighting mode, but not limited to this.

Among them, the first lighting mode is that the first lighting area L1 of the brake light device 5 is lighting; the second lighting mode is that the first lighting area L1 and the second lighting area L2 of the brake light device 5 are lighting The third lighting mode is that the first lighting area L1, the second lighting area L2 and the third lighting area L3 of the brake light device 5 are lighting, and the fourth lighting mode is the first lighting mode of the brake light device 5.

Threshold, among which, the percentage range of the first preset threshold is not more than 25%, the ratio range of the second preset threshold is more than 25% to not more than 50%, and the ratio range of the third preset threshold is more than 50% to not more than 50%. More than 75%, and the proportion of the fourth preset threshold is more than 75%, but not limited thereto, more preset thresholds can be set to subdivide the degree of braking, and finally a judgment result is generated based on these preset thresholds.

As shown in step S9, the control unit 4 outputs the corresponding light signal control command to the brake light device 5 according to the above-mentioned judgment result, and then in step S11, the brake light device 5 turns on the corresponding lighting mode according to the light signal control command. In the embodiment, the lighting modes are divided into the first lighting mode, the second lighting mode, the third lighting mode and the fourth lighting mode. This lighting mode is as mentioned above, so it will not be described again. In one embodiment, if the above-mentioned calculated displacement ratio is 20%, then it is within the range of the first preset threshold not exceeding 25%. At this time, the control unit 4 can output the corresponding first threshold based on this judgment result. The light signal control command of the first lighting mode is sent to the brake light device 5, and the brake light device 5 will turn on the first lighting mode, that is, the first lighting area L1 is lit with the first brightness, so that vehicles coming from behind can know the vehicle The braking situation.

To sum up, in the step-by-step brake light display method and system of the present invention, after the sensing unit senses the displacement of the pedal part of the brake unit, the calculation and processing unit receives the calculation of the displacement and generates a judgment result. The control unit can According to the judgment result, the light signal control command is output to the brake light device, so that the brake light device turns on the corresponding lighting mode. Therefore, the present invention can have different lighting forms according to the braking situation, thereby greatly improving the warning effect, and meeting the purpose of the present invention .
