Description

Technical Field

[0001] This application belongs to the technical field of automotive braking, and particularly relates to a brake light system capable of displaying braking intensity. Background Art

[0002] The brake light system is an important component of a vehicle. It can light up when the vehicle brakes, so as to remind the following vehicle that the preceding vehicle is braking and decelerating, ensuring driving safety and reducing the risk of traffic accidents.

[0003] Currently, the brake light has only two working states: on and off. It can meet the deceleration judgment needs of the following driver when the vehicle distance is large enough. However, with the increasing annual vehicle ownership, there are more and more vehicles on the road, resulting in a larger traffic flow and gradually smaller driving distances. Moreover, with the development of road traffic, the working condition of vehicles traveling at high speeds is becoming more and more common. Vehicles stop and go quickly, and the dense vehicles block the driver's line of sight to a certain extent. In addition, the following driver cannot judge the braking intensity of the preceding vehicle based on the brake light of the preceding vehicle, which leads to frequent rear-end collisions. Utility Model Content

[0004] This application provides a brake light system capable of displaying braking intensity, so that the following driver can judge the braking intensity of the preceding vehicle based on the brake light of the preceding vehicle, reducing the occurrence of rear-end collisions.

[0005] The technical solution adopted in this application is as follows:

[0006] A brake light system capable of displaying braking intensity, comprising:

[0007] A pressure sensor, which is arranged on the braking trigger mechanism and is used to detect the force of stepping on the brake pedal;

[0008] A brake light, which has a fixed lighting area and a variable lighting area;

[0009] A brake light controller, which is signal-connected to the pressure sensor and is used to control the brake light to turn on or off. When stepping on the brake pedal, the brake light controller controls the fixed lighting area to turn on. When the pressure sensor detects that the force of stepping on the brake pedal is greater than the set value, the brake light controller controls the variable lighting area to turn on, and the brightness of the variable lighting area gradually increases as the stepping force increases;

[0010] Or, when stepping on the brake pedal, the brake light controller controls the fixed lighting area and the variable lighting area to turn on, and the brightness of the variable lighting area is less than the brightness of the fixed lighting area. When the pressure sensor detects that the force of stepping on the brake pedal is greater than the set value, the brake light controller controls the brightness of the variable lighting area to increase, and the brightness of the variable lighting area gradually increases as the stepping force increases.

[0011] By adopting the above technical solution, when the driver gently steps on the brake pedal of a vehicle equipped with the brake light system in this application, the brake light controller sends a signal to the fixed-lighting area, and then the fixed-lighting area lights up to remind the following vehicle; when the driver steps on the brake pedal deeply, the pressure sensor detects that the force of stepping on the brake pedal is greater than the preset value. At this time, the brake light controller receives the signal from the pressure sensor and sends a signal to the variable-lighting area, so that the variable-lighting area lights up, and as the force of stepping on the brake pedal gradually increases, the brightness of the variable-lighting area gradually increases, so as to warn the following vehicle that this vehicle is making an emergency brake.

[0012] When the driver gently steps on the brake pedal of a vehicle equipped with the brake light system in this application, the brake light controller sends a signal to the fixed-lighting area and the variable-lighting area, and then the fixed-lighting area and the variable-lighting area light up to remind the following vehicle; when the driver steps on the brake pedal deeply, the pressure sensor detects that the force of stepping on the brake pedal is greater than the preset value. At this time, the brake light controller receives the signal from the pressure sensor and sends a signal to the variable-lighting area, so that the brightness of the variable-lighting area, and as the force of stepping on the brake pedal gradually increases, the brightness of the variable-lighting area gradually increases, so as to warn the following vehicle that this vehicle is making an emergency brake.

[0013] In summary, the brake light system in this application can adjust the brightness of the brake light according to the force of stepping on the brake pedal, so that the following vehicle can judge the braking intensity according to the brightness of the variable-lighting area of the brake light of the vehicle in front, so as to improve the warning effect on the following vehicle, so that the following vehicle can operate its own braking intensity according to the vehicle distance and the braking intensity of the vehicle in front, so as to increase the driving safety and greatly reduce the occurrence of traffic accidents.

[0014] In addition, since the brake light in this application has a fixed-lighting area and a variable-lighting area, the brightness of the fixed-lighting area remains unchanged, while the brightness of the variable-lighting area can change according to the force of stepping on the brake pedal, so as to increase the reminder effect of the brake light on the following vehicle on the premise of ensuring the original reminder effect of the vehicle brake light.

[0015] Optionally, the pressure sensor has a detection end acting on the brake pedal, so that the pressure sensor can detect the force of stepping on the brake pedal.

[0016] By adopting the above technical solution, when the driver steps on the brake pedal, the brake pedal acts on the detection end of the pressure sensor, and then the detection end directly detects the force of stepping on the brake pedal, so as to ensure the accuracy of detecting the force of stepping on the brake pedal.

[0017] Optionally, the brake trigger mechanism has a master cylinder, and the pressure sensor is arranged on the master cylinder, so that the pressure sensor calculates the force of stepping on the brake pedal according to the pressure of the braking medium.

[0018] By adopting the above technical solution, when the driver steps on the brake pedal, the brake pedal acts on the master cylinder, and then the pressure of the brake medium in the master cylinder gradually increases. At this time, the pressure sensor detects the pressure of the brake medium to reflect the force of stepping on the brake pedal by detecting the pressure of the brake medium; the pressure sensor is arranged on the master cylinder, so that the pressure sensor can form an avoidance with the brake pedal, so as to achieve the effect of facilitating the driver to step on the brake pedal, and at the same time avoid the situation that the driver's foot feeling is affected due to the pressure sensor acting on the brake pedal, thereby ensuring the driver's driving experience; in addition, compared with the pressure sensor acting on the brake pedal, the situation of needing to calibrate and position the pressure sensor is avoided, so as to greatly improve the installation efficiency of the pressure sensor.

[0019] Optionally, the brake lamp controller is signal-connected to the ABS controller, so that the brake lamp controller can control the brightness change of the brightening area according to the vehicle deceleration calculated by the ABS controller.

[0020] By adopting the above technical solution, when the driver steps on the brake pedal, the vehicle starts to brake. At this time, the ABS controller can calculate the deceleration of the vehicle. When the deceleration of the vehicle is greater than the set value, the ABS controller sends a signal to the brake lamp controller, and then the ABS control changes the brightness of the brightening area, so that the brake lamp controller can adjust the brightness of the brightening area according to the deceleration calculated by the ABS controller, so as to achieve dual control of the brightness change of the brightening area, so as to avoid the situation that the brightness of the brightening area cannot change due to the failure of one of the pressure sensor or the ABS controller, thereby ensuring the stability of the brake lamp system.

[0021] Optionally, the fixed bright area is arranged around the brightening area.

[0022] By adopting the above technical solution, since the fixed bright area is arranged around the brightening area, the reminder effect on the following vehicle when the brightening area is lit and the brightness becomes brighter is increased, and at the same time, the situation that the brightening area is lit or the brightness becomes brighter is too abrupt and the following vehicle does not understand the reminder effect is avoided.

[0023] Optionally, the fixed bright area includes a first fixed bright area and a second fixed bright area surrounding the first fixed bright area and the brightening area.

[0024] By adopting the above technical solution, when the driver brakes heavily, the first fixed bright area, the second fixed bright area and the brightening area are all lit, and the brightness change of the brightening area is the brightest. Since the second fixed bright area surrounds the first fixed bright area and the brightening area, the inside of the second fixed bright area is completely lit and in a brighter state, so as to further increase the reminder effect on the following vehicle.

[0025] Optionally, a plurality of the brightening areas are sequentially arranged. When the force of stepping on the brake pedal is greater than a set value and gradually increases, the brightness of the plurality of brightening areas increases sequentially.

[0026] By adopting the above technical solution, when the force of the driver stepping on the brake pedal is greater than the set value and gradually increases, the brightness of the plurality of brightening areas increases sequentially. Then, the driver of the following vehicle can more clearly understand that the braking force of the vehicle ahead is gradually increasing, so that the following vehicle can timely take braking measures or make evasions, so as to further improve the reminder effect on the following vehicle and further reduce the occurrence of traffic accidents.

[0027] Optionally, the plurality of brightening areas are sequentially arranged in the vertical direction. The first fixed brightening area is located at the bottom of the plurality of brightening areas. When the force of stepping on the brake pedal is greater than the set value and gradually increases, the brightness of the plurality of brightening areas increases from bottom to top sequentially.

[0028] By adopting the above technical solution, when the force of the driver stepping on the brake pedal is greater than the set value and gradually increases, the brightness of the plurality of brightening areas increases from bottom to top gradually, and the first fixed brightening area is located at the bottom of the brightening areas. Then, the reminder effect on the driver of the following vehicle is improved, so as to further reduce the occurrence of traffic accidents.

[0029] Optionally, the brightening areas are provided with multiple circles and are all arranged around the fixed brightening area. When the force of stepping on the brake pedal is greater than the set value and gradually increases, the brightness of the multiple circles of brightening areas increases from inside to outside gradually.

[0030] By adopting the above technical solution, when the force of the driver stepping on the brake pedal is greater than the set value and gradually increases, the brightness of the multiple circles of brightening areas increases from inside to outside gradually. Then, the reminder effect on the driver of the following vehicle is increased, so as to further reduce the occurrence of traffic accidents.

[0031] Optionally, the fixed brightening area includes a first fixed brightening area located inside the brightening area and a second fixed brightening area located around the brightening area.

[0032] By adopting the above technical solution, when the driver steps on the brake pedal, the first fixed brightening area and the second fixed brightening area located outside the first fixed brightening area are lit. When the force of the driver stepping on the brake pedal is greater than the set value, the brightness of the brightening area gradually becomes brighter, so as to remind the driver of the following vehicle that the vehicle ahead is performing a heavy braking operation. Through the setting of the second fixed brightening area, the second fixed brightening area can delineate the lit area, so as to increase the reminder effect on the following vehicle and avoid the situation that the lit area is abrupt and the following vehicle does not understand its function.

[0033] Due to the adoption of the above technical solution, the beneficial effects obtained by this application are:

When the pressure sensor detects that the force of stepping on the brake pedal is greater than a set value, the brake light controller controls the variable illumination area to light up, and the brightness of the variable illumination area gradually increases as the stepping force continuously increases. The brake light system in this application can adjust the brightness of the brake light according to the force of stepping on the brake pedal, so that the following vehicle can judge the braking intensity based on the brightness of the variable illumination area of the brake light of the vehicle in front, to improve the warning effect on the following vehicle, so that the following vehicle can operate its own braking intensity according to the vehicle distance and the braking intensity of the vehicle in front, to increase driving safety and greatly reduce the occurrence of traffic accidents.

The brake triggering mechanism in this application has a master brake cylinder, and the pressure sensor is disposed on the master brake cylinder, so that the pressure sensor calculates the force of stepping on the brake pedal according to the pressure of the brake medium. When the driver steps on the brake pedal, the brake pedal acts on the master brake cylinder, and then the pressure of the brake medium in the master brake cylinder gradually increases. At this time, the pressure sensor detects the pressure of the brake medium to reflect the force of stepping on the brake pedal by detecting the pressure of the brake medium; the pressure sensor is disposed on the master brake cylinder, so that the pressure sensor can form an avoidance with the brake pedal, to achieve the effect of facilitating the driver to step on the brake pedal, and at the same time avoid the situation that the driver's foot feeling is affected because the pressure sensor acts on the brake pedal, thereby ensuring the driver's driving experience; in addition, compared with the pressure sensor acting on the brake pedal, the situation of needing to calibrate and position the pressure sensor is avoided, so as to greatly improve the installation efficiency of the pressure sensor.

In the description of this specification, the description with reference to terms such as "an embodiment", "some embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of this application. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0047] Referring to Figure 1 and Figure 2 , a brake light system capable of displaying the braking intensity is disclosed, which includes a pressure sensor 1, a brake light 2, and a brake light controller 3. The pressure sensor 1 is arranged on a brake trigger mechanism 4 and is used to detect the force of stepping on a brake pedal 41; the brake light 2 has a constant-brightness area 21 and a variable-brightness area 22; the brake light controller 3 is signal-connected to the pressure sensor 1 and is used to control the brake light 2 to turn on or off. When stepping on the brake pedal 41, the brake light controller 3 controls the constant-brightness area 21 to turn on. When the pressure sensor 1 detects that the force of stepping on the brake pedal 41 is greater than a set value, the brake light controller 3 controls the variable-brightness area 22 to turn on, and the brightness of the variable-brightness area 22 gradually increases as the stepping force continuously increases.

[0048] It should be noted that the brake trigger mechanism 4 includes a brake pedal 41 and a master brake cylinder 42. The brake pedal 41 acts on the master brake cylinder 42 so that when stepping on the brake pedal 41, the brake pedal 41 applies pressure to a brake medium inside the master brake cylinder 42 to make the vehicle perform a braking operation. The constant-brightness area 21 is an area with a constant brightness, and the variable-brightness area 22 is an area whose brightness can change under the action of the brake light controller 3.

[0049] When a driver gently steps on the brake pedal 41 of a vehicle equipped with the brake light 2 system in this application, the brake light controller 3 sends a signal to the constant-brightness area 21, and then the constant-brightness area 21 is turned on to remind the following vehicle; when the driver deeply steps on the brake pedal 41, the pressure sensor 1 detects that the force of stepping on the brake pedal 41 is greater than a preset value. At this time, the brake light controller 3 receives the signal from the pressure sensor 1 and sends a signal to the variable-brightness area 22, so that the variable-brightness area 22 is turned on, and as the stepping force on the brake pedal 41 gradually increases, the brightness of the variable-brightness area 22 gradually increases, so as to achieve the effect of warning the following vehicle that this vehicle is performing an emergency brake.

[0050] In this embodiment, there is no specific limitation on the lighting method of the fixed lighting area 21. It can be as shown in the drawings, where a signal is sent to the brake light controller 3 through the original detection structure of the vehicle to light up the fixed lighting area 21. It can also be that when the pressure sensor 1 detects the force of stepping on the brake pedal 41, the pressure sensor 1 sends a signal to the brake light controller 3 to light up the fixed lighting area 21.

[0051] In another embodiment, referring to Figure 1 and Figure 2 , when stepping on the brake pedal 41, the brake light controller 3 controls the fixed lighting area 21 and the variable lighting area 22 to light up, and the brightness of the variable lighting area 22 is less than that of the fixed lighting area 21. When the pressure sensor 1 detects that the force of stepping on the brake pedal 41 is greater than the set value, the brake light controller 3 controls the brightness of the variable lighting area 22 to become brighter, and as the stepping force increases, the brightness of the variable lighting area 22 gradually increases and finally becomes the same as that of the fixed lighting area 21.

[0052] That is to say, when the driver lightly steps on the brake pedal 41 of the vehicle equipped with the brake light 2 system in this application, the brake light controller 3 sends signals to the fixed lighting area 21 and the variable lighting area 22, and then the fixed lighting area 21 and the variable lighting area 22 are lit to remind the following vehicle. When the driver deeply steps on the brake pedal 41, the pressure sensor 1 detects that the force of stepping on the brake pedal 41 is greater than the preset value. At this time, the brake light controller 3 receives the signal from the pressure sensor 1 and sends a signal to the variable lighting area 22, so that the brightness of the variable lighting area 22, and as the stepping force on the brake pedal 41 gradually increases, the brightness of the variable lighting area 22 gradually increases, so as to warn the following vehicle that this vehicle is making an emergency brake.

[0053] In summary, the brake light 2 system in this application can adjust the brightness of the brake light 2 according to the force of stepping on the brake pedal 41, so that the following vehicle can judge the braking intensity according to the brightness of the variable lighting area 22 of the brake light 2 of the vehicle in front, providing more accurate braking intensity information for the driver of the following vehicle, improving the warning effect on the following vehicle, so that the following vehicle can operate its own braking intensity according to the vehicle distance and the braking intensity of the vehicle in front, increasing driving safety, greatly reducing the occurrence of traffic accidents, especially providing guarantee for driving safety in a large traffic flow and close following driving.

[0054] In addition, since the brake light 2 in this application has a fixed lighting area 21 and a variable lighting area 22, the brightness of the fixed lighting area 21 remains unchanged, while the brightness of the variable lighting area 22 can change according to the force of stepping on the brake pedal 41, so as to increase the reminder effect of the brake light 2 on the following vehicle on the premise of ensuring the original reminder effect of the vehicle brake light 2.

[0055] In this embodiment, there are no specific limitations on the lighting methods of the constant lighting area 21 and the variable lighting area 22. It can be as shown in the drawings, where signals are sent to the brake light controller 3 through the original detection structure of the vehicle to light up the constant lighting area 21 and the variable lighting area 22; it can also be that when the pressure sensor 1 detects the force of stepping on the brake pedal 41, the pressure sensor 1 sends a signal to the brake light controller 3 to light up the constant lighting area 21 and the variable lighting area 22.

[0056] This application does not specifically limit the signal connection method between the pressure sensor 1 and the brake light controller 3. The signal connection between the two can be achieved using signal lines, and can also be achieved using a wireless transmission module.

[0057] This application does not specifically limit the installation position of the pressure sensor 1, and any of the following embodiments can be adopted:

[0058] Embodiment 1: In this embodiment, the pressure sensor 1 has a detection end that acts on the brake pedal 41, so that the pressure sensor 1 can detect the force of stepping on the brake pedal 41.

[0059] It can be understood that the pressure sensor 1 is installed on the vehicle body of the vehicle or on the master brake cylinder 42, so that when the driver steps on the brake pedal 41, pressure can be applied to the detection end of the pressure sensor 1.

[0060] When the driver steps on the brake pedal 41, the brake pedal 41 acts on the detection end of the pressure sensor 1, and then the detection end directly detects the force of stepping on the brake pedal 41 to ensure the accuracy of the detection of the force of stepping on the brake pedal 41.

[0061] Embodiment 2: In this embodiment, referring to Figure 1 , the braking trigger mechanism 4 has a master brake cylinder 42, and the pressure sensor 1 is arranged on the master brake cylinder 42, so that the pressure sensor 1 calculates the force of stepping on the brake pedal 41 according to the pressure of the braking medium.

[0062] It can be understood that the pressure sensor 1 is integrated into the master brake cylinder 42, and the braking medium in the master brake cylinder 42 can act on the pressure sensor 1, so that the pressure sensor 1 can detect the pressure of the braking medium to indirectly reflect the force of stepping on the brake pedal 41.

[0063] When the driver steps on the brake pedal 41, the brake pedal 41 acts on the master brake cylinder 42, and then the pressure of the braking medium in the master brake cylinder 42 gradually increases. At this time, the pressure sensor 1 detects the pressure of the braking medium to reflect the force of stepping on the brake pedal 41 by detecting the pressure of the braking medium; the pressure sensor 1 is arranged on the master brake cylinder 42, so that the pressure sensor 1 can form an avoidance with the brake pedal 41, so as to achieve the effect of facilitating the driver to step on the brake pedal 41, and at the same time avoid the situation that the driver's foot feeling is affected because the pressure sensor 1 acts on the brake pedal 41, thus ensuring the driver's driving experience; in addition, compared with the situation where the pressure sensor 1 acts on the brake pedal 41, the situation of needing to calibrate and position the pressure sensor 1 is avoided, so as to greatly improve the installation efficiency of the pressure sensor 1.

[0064] In a preferred embodiment, referring to Figure 1 , the brake lamp controller 3 is signal-connected to the ABS controller 5, so that the brake lamp controller 3 can control the brightness change of the brightening area 22 according to the vehicle deceleration calculated by the ABS controller 5.

[0065] When the driver steps on the brake pedal 41, the vehicle starts to brake. At this time, the ABS controller 5 can calculate the deceleration of the vehicle. When the deceleration of the vehicle is greater than the set value, the ABS controller 5 sends a signal to the brake lamp controller 3, and then the ABS control changes the brightness of the brightening area 22, so that the brake lamp controller 3 can adjust the brightness of the brightening area 22 according to the deceleration calculated by the ABS controller 5, so as to realize the dual control of the brightness change of the brightening area 22, so as to avoid the situation that the brightness of the brightening area 22 cannot change due to the failure of either the pressure sensor 1 or the ABS controller 5, thus ensuring the stability of the brake lamp 2 system.

[0066] This application does not specifically limit the signal connection method between the ABS controller 5 and the brake lamp controller 3. It can realize the signal connection between the two by using signal wires, or it can also adopt the wireless module transmission method to realize the signal connection between the two.

[0067] This application does not specifically limit the positional relationship between the fixed bright area 21 and the brightening area 22. Any one of the following embodiments can be adopted:

[0068] Embodiment 1. In this embodiment, the fixed bright area 21 is arranged around the brightening area 22, which increases the reminder effect on the following vehicle when the brightening area 22 is lit and after the brightness area 22 becomes bright, and at the same time avoids the situation that the brightening area 22 is lit or the brightness becomes bright abruptly, resulting in the following vehicle not understanding the reminder effect.

[0069] Further, referring to Figure 1, the fixed bright area 21 includes a first fixed bright area 21 and a second fixed bright area 21 surrounding the first fixed bright area 21 and the variable bright area 22.

[0070] When the driver brakes heavily, the first fixed bright area 21, the second fixed bright area 21, and the variable bright area 22 are all lit up, and the brightness change of the variable bright area 22 is the brightest. Since the second fixed bright area 21 surrounds the first fixed bright area 21 and the variable bright area 22, the inside of the second fixed bright area 21 is completely lit up and in a relatively bright state, so as to further increase the reminder effect on the following vehicle.

[0071] Furthermore, referring to Figure 1 , a plurality of variable bright areas 22 are arranged in sequence. When the force on the brake pedal 41 stepped on by the driver is greater than the set value and gradually increases, the brightness of the plurality of variable bright areas 22 increases in sequence.

[0072] When the force on the brake pedal 41 stepped on by the driver is greater than the set value and gradually increases, the brightness of the plurality of variable bright areas 22 increases in sequence, so that the driver of the following vehicle can more clearly understand that the braking force of the vehicle in front is gradually increasing, so that the following vehicle can take braking measures or make evasions in time, so as to further improve the reminder effect on the following vehicle and further reduce the occurrence of traffic accidents.

[0073] In this embodiment, the positional relationship between the variable bright area 22 and the first fixed bright area 21 is not specifically limited. Preferably, a plurality of variable bright areas 22 are arranged in sequence in the vertical direction, the first fixed bright area 21 is located at the bottom of the plurality of variable bright areas 22, and when the force on the brake pedal 41 stepped on by the driver is greater than the set value and gradually increases, the brightness of the plurality of variable bright areas 22 increases from bottom to top in sequence.

[0074] When the force on the brake pedal 41 stepped on by the driver is greater than the set value and gradually increases, the brightness of the plurality of variable bright areas 22 gradually increases from bottom to top, and the first fixed bright area 21 is located at the bottom of the variable bright area 22, so that the first fixed bright area 21 and the variable bright area 22 jointly form a display effect similar to an energy column, thus improving the reminder effect on the driver of the following vehicle and further reducing the occurrence of traffic accidents.

[0075] It should be noted that the above-mentioned "the brightness of the plurality of variable bright areas 22 increases from bottom to top in sequence" means that when the force on the brake pedal 41 is greater than the set value and gradually increases, the brightness of the variable bright area 22 at the bottom increases first, and then as the force on the brake pedal 41 increases, the brightness of the variable bright area 22 above the variable bright area 22 at the bottom increases.

[0076] In other embodiments, it can also be as shown in the drawings, where the first fixed bright area 21 is located at the top of the plurality of variable bright areas 22.

[0077] Embodiment 2. In this embodiment, referring to Figure 2 , the brightening area 22 is provided with multiple circles and is arranged around the fixed bright area 21. When the force applied to the brake pedal 41 is greater than the set value and gradually increases, the brightness of the multiple circles of the brightening area 22 gradually increases from the inside to the outside.

[0078] It can be understood that the lighting effect of the brightening area 22 is annular, and the multiple circles of the brightening area 22 are sleeved with each other.

[0079] When the force applied by the driver to the brake pedal 41 is greater than the set value and gradually increases, the brightness of the multiple circles of the brightening area 22 gradually increases from the inside to the outside, thereby increasing the prompting effect on the driver of the following vehicle and further reducing the occurrence of traffic accidents.

[0080] It should be noted that the above-mentioned "the brightness of the multiple circles of the brightening area 22 gradually increases from the inside to the outside" means that when the force applied to the brake pedal 41 is greater than the set value and gradually increases, the brightness of the brightening area 22 in the innermost circle increases first, and then as the force applied to the brake pedal 41 continues to increase, the brightness of the brightening area 22 in the outer circle of the innermost circle increases.

[0081] Further, referring to Figure 2 , the fixed bright area 21 includes a first fixed bright area 21 located inside the brightening area 22 and a second fixed bright area 21 located around the brightening area 22.

[0082] When the driver steps on the brake pedal 41, the first fixed bright area 21 and the second fixed bright area 21 located outside the first fixed bright area 21 are lit. When the force applied by the driver to the brake pedal 41 is greater than the set value, the brightness of the brightening area 22 gradually brightens to remind the driver of the following vehicle that the vehicle in front is performing a heavy braking operation. Through the setting of the second fixed bright area 21, the second fixed bright area 21 can demarcate the lit area to increase the reminder effect on the following vehicle, and at the same time avoid the situation where the lit area is abrupt and the following vehicle does not understand its function.

[0083] The following further gives an example with three brightening areas 22 in the above-mentioned Embodiment 1 and Embodiment 2. The fixed bright area 21 and the three brightening areas 22 correspond to four braking intensities, and the four braking intensities are the first stage, the second stage, the third stage, and the fourth stage respectively.

[0084] In the first stage, when the braking medium is brake fluid, the pressure of the brake fluid is less than or equal to 1 MPa. When the braking medium is gas, the pressure of the gas is less than or equal to 0.1 MPa, and the deceleration of the vehicle calculated by the ABS controller 5 is less than or equal to 1 m / s 2 , at this time, the fixed bright area 21 is lit, or the fixed bright area 21 and the three brightening areas 22 are all lit, but the brightness of the brightening area 22 is relatively low.

[0085] In the second stage, when the braking medium is brake fluid, if the pressure of the brake fluid is greater than 1 MPa and less than or equal to 3.5 MPa, or when the braking medium is gas, if the pressure of the gas is greater than 0.1 MPa and less than or equal to 0.3 MPa, or if the vehicle deceleration calculated by the ABS controller 5 is greater than 1 m / s 2 less than or equal to 3 m / s 2 , at this time, the brightness of the first brightening area 22 increases and becomes the maximum brightness display.

[0086] In the third stage, when the braking medium is brake fluid, if the pressure of the brake fluid is greater than 3.5 MPa and less than or equal to 6 MPa, or when the braking medium is gas, if the pressure of the gas is greater than 0.3 MPa and less than or equal to 0.6 MPa, or if the vehicle deceleration calculated by the ABS controller 5 is greater than 3 m / s 2 less than or equal to 5 m / s 2 , at this time, the brightness of the second brightening area 22 also increases and becomes the maximum brightness display.

[0087] In the fourth stage, when the braking medium is brake fluid, if the pressure of the brake fluid is greater than 6 MPa, or when the braking medium is gas, if the pressure of the gas is greater than 0.6 MPa, or if the vehicle deceleration calculated by the ABS controller 5 is greater than 5 m / s 2 , at this time, the brightness of the third brightening area 22 also increases and becomes the maximum brightness display.

[0088] It should be noted that the above is only an example. The brightening of the three brightening areas 22 corresponding to the pressure of the specific braking medium or the deceleration signal calculated by the ABS controller 5 needs to be adjusted according to the calibration of the actual vehicle.

[0089] In other embodiments, the fixed brightening area 21 and the brightening area 22 can also be structures with a block-shaped lighting effect respectively.

[0090] It should be noted that the brake light 2 in this application can be a separate module, or it can also be a module integrated with a turn signal and a reverse light.

[0091] What has not been described in this application can be implemented by adopting or referring to the existing technology.

[0092] Each embodiment in this specification is described in a progressive manner. The same or similar parts among the embodiments can be referred to each other, and the key points of each embodiment are to illustrate the differences from other embodiments.

[0093] The above are only the embodiments of this application and are not used to limit this application. For those skilled in the art, this application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of this application shall be included within the scope of the claims of this application.
