Referring to fig. 1, a schematic structural diagram of an automotive stop lamp according to a preferred embodiment of the present invention is shown, in which the stop lamp 1 includes a main light emitting area 101 and an indicating light emitting area 102; whenever a braking event occurs in the vehicle, the primary light emitting zone 101 lights up; the indication light emitting region 102 includes a plurality of light emitting cells L1, L2, L3 … … Lx … … Ln, and the light emitting cells L1, L2, L3 … … Lx … … Ln are sequentially arranged at one side of the main light emitting region 101; the indicator light emitting zone 102 illuminates the corresponding light emitting unit based on the brake pedal travel of the braking event.
Referring to fig. 2, the light emitting units are sequentially arranged at two sides of the main light emitting region, so that two sides of the main light emitting region are respectively arranged with a group of light emitting units L1, L2, L3 … … Lx … … Ln, L1', L2', L3' … … Lx ' … … Ln '. Preferably, the two groups of light-emitting units are arranged symmetrically and have the same number, and the light-emitting units on both sides need to light the corresponding light-emitting units from the same direction at the same time.
The present invention does not limit that the main light emitting area 101 of the stop lamp is not necessarily horizontal, but may be vertical or irregular, as long as the indication area light emitting area 102 surrounds the indication area light emitting area.
Based on the above embodiments, in a preferred embodiment, the indication area light emitting area 102 needs to have a distinct boundary with the main light emitting area 101, and the brightness thereof needs to ensure that it is clearly visible when the main light emitting area 101 is lighted. The indication light emitting area 102 may or may not have a distinct spacing between the light emitting units.
In the technical scheme of the invention, the brake lamp 1 is composed of a main light emitting area 101 and a brake pedal travel indicating light emitting area 102, wherein the main light emitting area 101 is used for meeting the optical regulation requirement of the brake lamp, and emits light when the brake pedal is stepped on, and the light emitting intensity is enough, so that a driver of a following vehicle can clearly receive the braking action of a preceding vehicle, namely the occurrence of a braking event, and the light emitting intensity does not change along with the stepping depth of the brake pedal; the pedal stroke indication luminous zone 102 is composed of a plurality of luminous units which are sequentially distributed on one side or two sides of the main luminous zone and respectively correspond to different brake pedal strokes. With the change of the depth of stepping on the brake pedal, i.e. the pedal stroke, the light-emitting units at different positions are lighted, and the brightness and the lighting area of the indication light-emitting area 102 are changed. The present invention does not limit the number of light emitting units and the correspondence between the pedal stroke and the number of light emitting units to be lit, but as the depth of the pedal depression increases (the pedal stroke increases), the number of light emitting units in the indication light emitting region 102 to be lit increases. For example, taking the light emitting units indicating the light emitting regions 102 located at one side of the main light emitting region as an example, the pedal stroke is divided into 5 levels, and the light emitting units are 20L 1, L2, and L3 … … L20, so that L1-L4 are lit when the pedal stroke is at the first level, L1-L8 are lit when the pedal stroke is at the second level, L1-L12 are lit when the pedal stroke is at the third level, L1-L16 are lit when the pedal stroke is at the fourth level, and L1-L20 are all lit when the pedal stroke is at the fifth level. The above example is uniform variation with pedal stroke, and non-uniform variation is also within the protection scope of the present invention, for example, when the pedal stroke is in the first level, L1-L5 lights up, when the pedal stroke is in the second level, L1-L8 lights up, when the pedal stroke is in the third level, L1-L11 lights up, when the pedal stroke is in the fourth level, L1-L15 lights up, when the pedal stroke is in the fifth level, L1-L20 lights up completely. The number of the lighting units can be gradually increased from the starting end to the tail end along with the increase of the pedal stroke. The same is true when the light emitting units of the indication light emitting region 102 are located on both sides of the main light emitting region, and preferably, the two groups of light emitting units are symmetrically arranged and the light emitting units in the symmetrical positions are simultaneously lighted.
Preferably, the stroke of each unit of the light-emitting units from the starting end L1 to the most end Ln of the corresponding brake pedal in turn is equal in proportion from the starting to the maximum, i.e., the lighting change of the light-emitting units of the indication light-emitting area 102 is uniform along with the change of the pedal stroke. Preferably, the proportional correspondence is linear, and the light emitting unit is gradually lighted from the start end to the end as the pedal stroke increases.
Based on the above embodiments, in a preferred embodiment consistent with the present invention, the luminances of the light emitting cells L1, L2, and L3 … … Lx … … Ln when the indication light emitting region 102 is lit are uniform or the luminances of the light emitting cells L1, L2, and L3 … … Lx … … Ln from the beginning to the end of the indication light emitting region 102 are gradually increased, that is, the luminances of the light emitting cells closer to the end are increased.
Through the technical scheme, when the automobile brakes, the main light emitting area 101 emits light when the brake pedal is pressed down, the light emitting intensity is enough, so that a driver of a following vehicle can clearly receive the braking action of a preceding vehicle, and the light emitting unit of the indicating light emitting area 102 is gradually lightened from the starting end along with the change of the stroke of the brake pedal. If the user steps on the brake more gently and does not step on to the bottom, the driver of the rear vehicle will see that the main luminous zone 101 of the brake lamp of the front vehicle is lightened, a braking event occurs, the luminous units of the indication luminous zone 102 are gradually lightened, the strips formed by the indication luminous zone gradually become lighter and are not at the extreme end, if the user steps on the brake more quickly and steps on to the bottom, the driver of the rear vehicle will see that the main luminous zone 101 of the brake lamp of the front vehicle is lightened, a braking event occurs, the luminous units of the indication luminous zone 102 are quickly and completely lightened (although the strips are gradually lightened from the starting end to the end, the speed is very high), the strips formed by the indication luminous zone rapidly become to the extreme end, the driver of the rear vehicle will guide the brake of the front vehicle to be very steep, and the emergency brake is needed, therefore, the driver of the rear vehicle can make a decision on emergency brake at the first time instead of waiting for the. Therefore, the brake lamp can display the brake proportion, is beneficial to reminding other traffic participants of performing more timely and more accurate deceleration operation, improves the driving safety, and reduces the risk of rear-end collision and other accidents.

For example, according to the calculation, L1, L2, L3 … … L15 or L1, L2, L3 … … Lx should be lit according to the current pedal stroke, and the light emitting unit lighting information is L1, L2, L3 … … L15 or L1, L2, L3 … … Lx lighting, and the vehicle lamp control module controls the lighting of L1, L2, L3 … … L15 or L1, L2, L3 … … Lx light emitting units from the beginning. It should be noted that, the pedal stroke signal receiving unit receives the pedal stroke signal of the brake pedal stroke sensor 3 in real time, and the lighting information of the lighting unit formed by the vehicle body control module is also real time, so the vehicle body control module also controls the lighting of the corresponding lighting unit of the indication lighting area 102 according to the real-time lighting information of the lighting unit, and the lighting unit of the indication lighting area 102 changes in real time along with the change of the pedal stroke. It should be noted that the lighting of the main light emitting area 101 is not affected by the pedal stroke signal, and as long as the vehicle brakes, the main light emitting area 101 is lit and the brightness is not changed. In addition, the control mode of the main light emitting area is not limited, any control mode capable of lighting the main light emitting area when the automobile brakes can be adopted, for example, the lighting of the main light emitting area can be controlled according to a commonly used switch after the pedal passes through, or the lighting of the main light emitting area can be controlled according to the pedal stroke signal, when the pedal stroke signal is received, the main light emitting area and the indicating light emitting area are both lighted, only the brightness of the main light emitting area is constant, and the brightness and the lighting position of the indicating light emitting area are related to the pedal stroke signal, and the control mode is within the protection scope of the invention.

Similarly, if the light emitting units at all positions from the initial position to the specific position X are turned on, the following vehicle may determine the braking ratio based on the ratio or position of the turned-on light emitting units to the indication light emitting area 102 or the ratio or position of the bands formed by the light emitting units of the circuit to the indication light emitting area 102, or may determine the change of the pedal stroke of the driver based on the change (increase or decrease) and the speed of the change of the turned-on light emitting units, and if all the light emitting units of the indication light emitting area 102 are turned on quickly, the braking is rapid, and if only the light emitting units at a small position are turned on, the braking is gentle, and the following vehicle does not need to be braked rapidly.
Based on the above embodiments, according to a preferred embodiment of the present invention, when the positions of the light-emitting units to be lit in the light-emitting unit lighting information are all positions from the initial position to the specific position X, the initial position (the position where the lighting starts) is the position of the light-emitting unit near the side edge or the lower edge of the vehicle body in the indication light-emitting area 102, that is, when the light-emitting unit in the indication light-emitting area 102 is lit, the light-emitting unit is gradually lit inwards from the side edge or the lower edge of the vehicle body. For example, when the main light emitting region 101 runs horizontally, the initial position of the light emitting unit which is first lighted on the light emitting region 102 of the indication region is located at one side close to the outer edge of the vehicle body; when the main light emitting area 101 moves vertically, the initial position of the light emitting unit which is firstly turned on by the light emitting area 102 of the indication area is positioned at the position of the lower side of the vehicle body; when the main light emitting region 101 is abnormal, the initial position of the light emitting unit which is first turned on by the indication region light emitting region 102 is located at a position which is lower near the outer side of the vehicle body.
Fig. 5 is a schematic structural diagram of a brake light control system according to another preferred embodiment of the present invention, in which the vehicle body control module 2 is further included between the vehicle light control module 4 and the brake pedal travel sensor 3; the pedal stroke signal receiving unit of the vehicle body control module 2 receives the pedal stroke signal generated by the brake pedal stroke sensor 3, and the pedal stroke conversion unit calculates the position of the light-emitting unit of the indicating light-emitting area to be lightened according to the pedal stroke signal to form lightening information of the light-emitting unit; the communication unit transmits the lighting information of the light-emitting unit to the car light control module 4; and the car light control module 4 controls the corresponding light-emitting units in the brake lights 1 to be lightened according to the lightening information of the light-emitting units.
In this embodiment, when the brake pedal is depressed, the brake light main light emitting region is immediately lit. The travel sensor 3 of the brake pedal transmits a detected travel signal of the pedal to the automobile body control module 2 of the automobile in a wired or wireless mode, after the pedal travel signal receiving unit of the automobile body control module 2 receives the pedal travel signal, the pedal travel conversion unit calculates the position of the light-emitting unit needing to be lightened in the indicating light-emitting area according to the pedal travel signal, specifically, the position of the light-emitting unit needing to be lightened in the indicating light-emitting area in each country corresponds to the proportion of the current pedal travel in the whole pedal travel, namely the braking proportion, and the pedal travel signal can be converted into the position information of the light-emitting unit in the indicating light-emitting area to form the position information of the light-emitting unit. As described above, the present invention is not limited to the case where the light-emitting units to be lit are all light-emitting units from the start end to the specific position, and may be only light-emitting units at the specific position. Therefore, based on the above-mentioned embodiments, in a preferred embodiment consistent with the present invention, the positions of the light-emitting units to be lit in the light-emitting unit lighting information are the specific position X indicating the pedal stroke or all positions from the start position to the specific position X. As calculated, the position of the light emitting unit of the L15 or Lx position in the entire indication light emitting area 102 is opposite to the current pedal stroke, and the light emitting unit lighting information may be lighting all the light emitting units from the start to the L15 or Lx position, i.e., L1, L2, L3 … … L15 or L1, L2, L3 … … Lx, or lighting only the light emitting unit of the L15 or Lx position, according to which the corresponding light emitting unit is lighted. The two technical schemes can display the braking proportion of the brake pedal.
The pedal travel conversion unit calculates the position of the light-emitting unit of the indication light-emitting area needing to be lightened according to the pedal travel signal, and after the lightening information of the light-emitting unit is formed, the communication unit transmits the information to the car light control module 4 in the form of an analog signal or a digital signal. For example, in the form of PWM or communication commands (LIN or CAN) to the headlight control module 4. The car light control module 4 controls to light the light-emitting unit corresponding to the pedal stroke according to the light-emitting unit lighting information. Other traffic participants can judge the braking proportion of the vehicle by observing the position of the lighted luminous unit in the whole travel indication area or the proportion of the lighted luminous unit in the whole indication area, so that more timely and accurate operation is adopted, and accidents such as rear-end collision and the like are reduced.
Because part of the vehicle body control modules can collect and process the information of the travel of the brake pedal, the technical scheme can directly process the information of the travel of the brake pedal by the vehicle body control module under the condition, and the information of the travel of the brake pedal is calculated according to the sensor signal and then is transmitted to the vehicle lamp control module, so that the vehicle body wiring harness can be simplified, and the complexity of the vehicle lamp control module can be reduced.
Through the technical scheme, on one hand, when the brake pedal is stepped on, the main light emitting area 101 is immediately lightened to indicate that the vehicle brakes, and the brightness is enough to remind that the rear vehicle brakes, on the other hand, through the pedal travel signal detected by the brake pedal travel sensor 3, the vehicle light control module 4 controls the corresponding light emitting unit in the indicating light emitting area 102 of the brake light 1 to be lightened according to the received pedal travel signal, so that the pedal travel is indicated, namely, the braking proportion and the depth change of the brake pedal stepped on by the driver are indicated. Through this technical scheme, not only can remind the plantago car of back braking, can also effectually remind the plantago car concrete braking condition of back to make other traffic participants make more timely more accurate speed reduction operation, improve driving safety, reduce the risk of accidents such as rear-end collision. Compared with the traditional brake lamp which can only be simply turned on and off, the brake lamp and the brake system can provide a prompt of the brake proportion, and are helpful for reminding other traffic participants to perform more timely and accurate deceleration operation. Particularly, under the conditions of poor sight and unclear reference objects around, the driving safety can be obviously improved, and the risk of rear-end collision and other accidents is reduced.
The invention also provides a brake lamp control method, which is suitable for the brake lamp control system, and comprises the following steps: detecting whether a braking event and a corresponding brake pedal travel occur; when the braking event occurs, the main light emitting area is controlled to be lightened, so that the braking event is indicated to occur, and the rear vehicle in front of the vehicle is reminded of braking; and calculating the position of the light-emitting unit of the indicating light-emitting area to be lightened according to the travel of the brake pedal, and controlling the corresponding light-emitting unit to be lightened, so that the braking proportion is indicated through the light-emitting unit, and the rear vehicle is reminded of performing more timely and accurate deceleration operation.
Compared with the traditional braking mode that only the light-on and the light-off are carried out, the technical scheme of the invention can provide the prompt of the braking proportion, is beneficial to reminding other traffic participants of carrying out more timely and accurate deceleration operation, obviously improves the driving safety and reduces the risk of rear-end collisions and other accidents.
