Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1, an embodiment of the present invention provides a brake signal lamp control device for an automobile, which includes a brake pedal, a controller, and a brake signal lamp composed of a plurality of lamp blocks.

In this embodiment, the brake pedal includes a brake pedal lever and a foot-supporting member connected to the brake pedal lever, the foot-supporting member having a flat surface, a plurality of force-or pressure-sensitive sensors being disposed on the surface of the foot-supporting member; pressure-sensitive sensors (e.g., film sensors) or force-sensitive sensors adapted to the brake pedal are known to those skilled in the art and will not be described in detail herein.

It should be noted that the brake signal lamp may be configured to be composed of a plurality of lamp blocks with different colors. For example, a strip-shaped brake signal lamp is composed of four red and yellow lamp blocks, wherein the four lamp blocks are respectively provided with a power supply loop, and the power supply loops are respectively controlled to be switched on and off by a controller.

Specifically, the automobile brake signal lamp control device further comprises a braking part which is connected with the controller and used for braking the automobile according to a braking signal of a brake pedal.

As for the control method of the control device of the brake signal lamp of the automobile provided by the embodiment of the invention, as shown in fig. 2, the method specifically comprises the following steps:

s1: when the braking operation of the brake pedal exists, a braking signal of the brake pedal is obtained through a sensor on the brake pedal, and the braking signal is used for determining the braking depth of the brake pedal.

S2: the controller is respectively connected with the sensor of the brake pedal and the brake signal lamp and used for receiving the brake signal of the brake pedal and judging whether the brake depth of the brake pedal exceeds the upper limit value of the Nth preset depth interval or not according to the brake signal.

S21: if the braking depth of the brake pedal exceeds the upper limit value of the Nth preset depth interval, generating a lighting signal of the (N +1) light blocks before lighting, wherein N is a non-zero natural number; the brake signal lamp is used for receiving the lighting signal generated by the controller and lighting the corresponding lamp block according to the lighting signal.

S22: if the braking depth of the brake pedal does not exceed the upper limit value of the Nth preset depth interval, whether the current braking depth of the brake pedal exceeds the lower limit value of the Nth preset depth interval or not is further judged, and if the current braking depth of the brake pedal exceeds the lower limit value of the Nth preset depth interval, a lighting signal for lighting the front N lamp blocks is generated, so that the front N lamp blocks are correspondingly lighted by the brake signal lamp.

In the embodiment, when a driver steps on a brake pedal, a sensor on the brake pedal synchronously receives a brake signal generated by corresponding brake operation and sends the brake signal to a controller, wherein the brake signal is used for reflecting the brake depth of the brake pedal; and after receiving the braking signal, the controller generates a corresponding lighting signal according to the matching result between the braking depth of the brake pedal at each moment and a plurality of preset depth intervals, so that the brake signal lamp of the automobile displays a dynamically-lighted lamp block.

Specifically, the braking depth can be correspondingly converted into the travel of the brake pedal, and the change condition of the travel of the brake pedal is divided to set a corresponding depth interval; the stroke of the brake pedal comprises two parts, namely a front-section free stroke and a rear-section working stroke, wherein the front-section free stroke is a section of stroke of the brake pedal which is just treaded down but the vehicle is not braked, and the front-end free stroke is set to prevent a brake pad and a brake disc from being too tight and overheated to cause brake failure; the rear working stroke is the stroke of the pedal when the automobile starts to brake and decelerate to obtain the maximum braking deceleration.

It can be understood that the number of the depth intervals set in the embodiment of the invention is the same as the number of the lamp blocks of the brake signal lamp, and when the brake signal lamp is composed of four red and yellow lamp blocks, the brake depth of the brake pedal is correspondingly divided into four depth intervals.

Referring to fig. 3, specifically, 1) when the brake pedal is in a slack stable state without mechanical pressure, the power supply circuit of each light block in the brake signal lamp is in a disconnected state, and at this time, all the light blocks are not lighted; 2) when the braking depth reaches the range of the first depth interval, the braking depth of the brake pedal exceeds the lower limit value of the first depth interval and does not reach the upper limit value of the first depth interval, a sensor on the brake pedal sends a corresponding braking signal to a controller, so that a power supply loop corresponding to a first lamp block of a brake signal lamp is closed, the first lamp block is lightened, and the brake signal lamp displays red light; similarly, 3) when the braking depth reaches the range of the second depth interval, the sensor on the brake pedal sends a corresponding braking signal to the controller, so that power supply circuits corresponding to the first lamp block and the second lamp block of the brake signal lamp are closed, at the moment, the first lamp block and the second lamp block are both lightened, and the brake signal lamp displays red light and yellow light; 4) when the braking depth reaches the range of a third depth interval, a sensor on the brake pedal sends a corresponding braking signal to the controller, so that power supply circuits corresponding to a first lamp block, a second lamp block and a third lamp block of a brake signal lamp are closed, at the moment, the first lamp block, the second lamp block and the third lamp block are all lightened, and the brake signal lamp sequentially displays red light, yellow light and red light; 5) when the braking depth reaches the range of the fourth depth interval, the sensor on the brake pedal sends a corresponding braking signal to the controller, so that power supply circuits corresponding to the four lamp blocks of the brake signal lamp are closed, at the moment, the four lamp blocks are all lightened, and the brake signal lamp sequentially displays red light, yellow light, red light and yellow light.

It can be understood that, after the driver steps on the brake pedal and lights the four lamp blocks of the brake signal lamp, when the brake pedal is released, the controller correspondingly receives the brake depth of the released brake pedal at the corresponding moment, and if the brake depth of the corresponding moment does not enter a certain depth interval range, the lamp block corresponding to the depth interval is turned off.

The embodiment of the invention also provides a vehicle which comprises the automobile brake signal lamp control device in any embodiment of the invention.

According to the invention, the braking depth of the automobile brake pedal is quantized into a plurality of depth intervals, so that the lamp blocks of the brake signal lamp associated with the different depth intervals are dynamically lightened according to the current braking condition of a driver, the number of the lightened lamp blocks and the lightening time can more accurately display the current braking force and braking process of the driver, and the emergency degree of braking is visually presented, so that the driver of the rear vehicle can visually distinguish whether the front vehicle is lightly braked or heavily braked, the problem that the driver of the rear vehicle cannot visually and accurately judge the braking condition of the front vehicle in the prior art is solved, and the driving safety is effectively improved.

An embodiment of the present invention further provides a computer-readable storage medium, on which a computer program is stored, and when the computer program is executed by a processor, the method for managing service data according to any of the above embodiments is implemented. It will be understood by those skilled in the art that all or part of the processes of the methods of the embodiments described above can be implemented by hardware associated with instructions of a computer program, the computer program can be stored in a computer-readable storage medium, and the computer program can include the processes of the embodiments of the methods described above when the computer program is executed.
