Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
Fig. 1 is a schematic diagram of a brake light control system 100 shown in an exemplary embodiment of the present disclosure. As shown in fig. 1, the brake light control system 100 may include a detector 10 and a controller 20.
And a detector 10 for detecting information on depression of the brake pedal.
Wherein the depression information of the brake pedal can represent the depression speed of the brake pedal. When a driver needs to brake during the running process of the vehicle, the driver steps on the brake pedal according to actual conditions, and the stepping speed of the brake pedal is different. For example, in emergency braking, the driver quickly depresses the brake pedal, which is at a higher speed; when the brake is slowly braked, a driver lightly steps on the brake pedal, and the speed of the brake pedal is low at the moment. The detector 10 may be a rotation angle sensor mounted on the brake pedal, or may be a displacement sensor, which is not particularly limited herein.
And a controller 20 communicatively connected to the detector 10 and connected to the stop lamp 30 for controlling the brightness of the stop lamp 30 according to the stepping information.
In the present disclosure, the controller 20 may be a vehicle body controller, or may be other controllers on the vehicle (e.g., a separately provided brake light controller), and any control element capable of controlling the brightness of the brake light 30 may be used as the controller of the present disclosure. The controller 20 is connected to the detector 10 in communication with the stop lamp 30, and the controller 20 controls the brightness of the stop lamp 30 based on the depression information of the detector 10 after receiving the depression information.
In one embodiment, the detector 10 is a rotational angle sensor mounted on the brake pedal. When the driver depresses the brake pedal, the rotation angle sensor transmits the detected angular velocity of the brake pedal to the controller 20, and the controller 20 controls the brightness of the brake lamp 30 according to the angular velocity of the brake pedal. Specifically, during emergency braking, the angular velocity of the brake pedal is greater than the set angular velocity threshold, and the controller 20 may control the brake lamp 30 to be turned on at a first brightness value. Wherein the angular velocity threshold is used to distinguish between emergency braking and non-emergency braking. During slow braking, for example, when the driver brakes in a spot braking manner and the angular velocity of the brake pedal is less than or equal to the set angular velocity threshold, the controller 20 may control the brake lamp 30 to be turned on at the second brightness value. Wherein the first luminance value is greater than the second luminance value. Illustratively, the first luminance value may be a maximum luminance value that is allowed.
In another embodiment, the detector 10 is a displacement sensor mounted on the brake pedal. When the driver steps on the brake pedal, the displacement sensor transmits the detected displacement amount of the brake pedal to the controller 20, and the controller 20 determines the speed of the brake pedal according to the displacement amount, so as to control the brightness of the brake lamp 30 according to the speed of the brake pedal. Specifically, during emergency braking, the controller 20 determines that the speed of the brake pedal is greater than a set speed threshold (which is used to distinguish whether emergency braking or non-emergency braking is performed), and the controller 20 may control the brake lamp 30 to be turned on at a first brightness value. During slow braking, the controller determines that the speed of the brake pedal is less than or equal to the set speed threshold, and the controller may control the brake lamp 30 to illuminate at a second brightness value.
Through above scheme, the brake light control system can control the luminance of brake light according to the information of trampling of brake pedal, and like this, the driver of back car can judge the braking emergency degree of front truck according to the luminance of front truck brake light to make exact reaction, avoid the emergence of traffic accident.
In another embodiment of the present disclosure, the brake lamp control system 100 may further include a variable resistor module 40, wherein the variable resistor module 40 is a module with a variable resistance value, the variable resistor module 40 is connected in series with the brake lamp 30 and is connected to the controller 20, and the variable resistor module 40 is used for adjusting the brightness of the brake lamp 30.
The controller 20 is configured to determine a target resistance value of the variable resistance module 40 according to the pedaling information, and control the variable resistance module to connect the brake lamp in series with the target resistance value.
The target resistance value is the resistance value of the variable resistance module 40 corresponding to the current stepping information, which is determined by the controller 20 according to the preset corresponding relationship between the stepping information and the resistance value, and after the variable resistance module 40 serially connects the brake lamp 30 with the target resistance, the brightness of the brake lamp 30 is within the allowed brightness range. As described above, the depression information may indicate the speed at which the brake pedal is depressed. The stepping information indicates a negative correlation between the speed at which the brake pedal is stepped and the target resistance value. That is, the greater the speed at which the brake pedal is depressed, the smaller the corresponding target resistance value, so that the greater the current in the series circuit of the brake lamp 30, the brighter the brake lamp 30. The smaller the value of the speed at which the brake light is depressed, the larger the corresponding target resistance value, so that the smaller the current in the series circuit of the brake light 30, the darker the brake light 30. Thus, the controller 20 determines the target resistance value of the variable resistance module 40 according to the stepping information, and controls the variable resistance module 40 to connect the brake lamp 30 in series with the target resistance value, thereby realizing the brightness change of the brake lamp to remind the driver of the rear vehicle of making an accurate action in time, and avoiding rear-end collision or more serious traffic accidents.
Fig. 2 shows an example of the variable resistance module 40. As shown in fig. 2, the variable resistor module 40 may be a digital adjustable resistor, which may be formed with different resistance values under the control of the controller 20, so as to realize the change of the current in the brake lamp series circuit, thereby adjusting the brightness of the brake lamp.
Fig. 3 shows another example of the variable resistance module 40. As shown in fig. 3, the variable resistance module 40 may include a plurality of resistors, and a switch module 42. The resistors form a plurality of parallel branches, one branch is provided with one resistor or a plurality of resistors connected in series, and the total resistance values of the branches are different from each other. Therefore, different branches correspond to different brightness of the brake lamp, and the brightness of the brake lamp can be automatically adjusted along with the speed of the brake pedal. The resistance value of each of the plurality of resistors may be the same or different, and is not specifically limited herein. The number of the parallel branches can be set according to actual needs.
The controller 20 is configured to determine a target branch to be connected in series with the stop lamp 30 among the plurality of parallel branches according to the stepping information, connect the target branch in series with the stop lamp 30 by controlling the switch module 42, and keep disconnection between the other branches except the target branch and the stop lamp 30, wherein the target branch has a target resistance value.
In the present disclosure, a target branch is a branch whose branch resistance is a target resistance value. In an exemplary embodiment, as shown in FIG. 3, two parallel branches may be provided, wherein branch 401 is1Is provided with a resistor R1, branch 4012Resistors R2 and R3 are provided, and the total resistance value of the resistors R2 and R3 is larger than that of the resistor R1. Specifically, during emergency braking, the controller 20 determines the target resistance value as the resistance value of the resistor R1 according to the stepping information sent by the detector 10, so as to determine the target branch corresponding to the target resistance value as the branch 4011And further controls branch 401 via switch module 421Is turned on and branch 401 is2Off, at which time leg 4011In series with the stop lamp 30 such that the stop lamp 30 is illuminated at a first brightness value. During slow braking, the controller 20 determines the target resistance value to be the total resistance value of the resistors R2 and R3 according to the stepping information sent by the detector 10, so as to determine the target branch corresponding to the target resistance value to be the branch 4012And further controls branch 401 via switch module 422Is turned on and branch 401 is1Off, at which time leg 4012In series with the stop lamp 30 such that the stop lamp 30 is illuminated at a second brightness value. Wherein the first luminance value is greater than the second luminance value. Illustratively, the first luminance value may be a maximum luminance value that is allowed. Therefore, when the vehicle is braked emergently, the brake lamp is lightened at the allowed maximum value, so that a driver of the rear vehicle is warned, the front vehicle is in an emergency braking state, the driver of the rear vehicle makes a correct response, and traffic accidents are avoided.
As shown in fig. 3, the switch module 42 may include a plurality of switches corresponding to the plurality of parallel branches, each switch being connected in series with a resistor on the corresponding branch.
The controller 20 is configured to control the switches corresponding to the target branch to be closed and the switches corresponding to the branches other than the target branch to be opened.
It should be noted that, although fig. 3 illustrates how the switch module 42 controls the on/off of each branch by taking the switch module 42 including a plurality of switches as an example, the disclosure is not limited thereto, and other switch implementations capable of controlling the on/off of each branch are also applicable to the disclosure.
