Description
Technical Field
The utility model belongs to vehicle optical signal device field, concretely relates to vehicle brake lamp controlling means, system and have device and system's vehicle.
Background
Vehicle brake lights (as shown in fig. 1), which typically include a left side brake light and a right side brake light, are optical signal generating devices disposed at the rear of the vehicle. When the brake pedal in fig. 1 is depressed, the vehicle central controller receives a signal of the depression of the brake pedal (for example, a current signal caused by the circuit being turned on), and then issues lighting commands to the left side brake lamp and the right side brake lamp. The brake lamp receives the lighting signal and then lights to indicate that the coming vehicle behind keeps the distance from the preceding vehicle, so that the purpose of ensuring the safe driving of the vehicle is achieved. However, the brake lamp of the vehicle in the prior art is only controlled by the brake pedal to be turned on, so that when the speed of the rear vehicle in the driving direction is too high and the front vehicle does not have braking action, the brake lamp cannot play a role in prompting the rear vehicle to decelerate and brake.
The vehicle rear sensors (shown as a right 1 sensor, a right 2 sensor, a left 1 sensor, and a left 2 sensor in fig. 2) are radar signal transmitting and receiving devices arranged on a rear bumper of the vehicle. When the vehicle is backed, the sensor emits a radar signal and receives the radar signal reflected from an obstacle (e.g., other vehicle, a wall, a flower stand, etc.), and provides the received signal to the vehicle central controller for processing, thereby detecting a distance to a rear obstacle. When the vehicle central controller judges that the vehicle is too close to the rear obstacle and the collision is possible according to the detected distance, the vehicle central controller sends an instruction to the loudspeaker to enable the loudspeaker to send a sound signal to prompt a driver so as to prevent the vehicle from colliding with the obstacle, and therefore the purpose of protecting the vehicle is achieved. However, the vehicle rear sensor in the prior art is only activated when the vehicle is in reverse (the vehicle gear is selected to be in reverse), and therefore, the vehicle rear sensor only plays a role in protection when the vehicle is in reverse.
In the statistics of vehicle accident causes, vehicle rear-end collision is a common accident form, and the accident cause of the vehicle rear-end collision is mainly due to the fact that the distance between adjacent front and rear vehicles is too small in the driving process. The existing vehicle brake lamp is only controlled by a brake pedal to be lightened, so that when the speed of a rear vehicle in the driving direction is too high or the distance between the two vehicles is too short and the front vehicle does not have braking action, the brake lamp cannot play a role in prompting the deceleration and braking of the rear vehicle.

Detailed Description
The present invention relates to a vehicle brake light control device, a system and a vehicle including the vehicle brake light control device, which will be described in further detail with reference to the accompanying drawings. It is to be noted that the following detailed description is exemplary rather than limiting, is intended to provide a basic understanding of the invention, and is not intended to identify key or critical elements of the invention or to delineate the scope of the invention.

Fig. 3 is a schematic structural diagram of a vehicle brake lamp control device 300 according to an embodiment of the first aspect of the present invention. According to a first aspect of the present invention, in one embodiment, the vehicle brake light control device 300 comprises a vehicle central controller 310 and a sensor 320, wherein the first output O1 of the vehicle central controller 310 is directly coupled to the brake light 340 without the logic judger 360 shown in fig. 3. When the vehicle travels forward, the sensor 320 coupled to the vehicle central controller 310 detects a distance between the vehicle in which it is located and another vehicle adjacent to the vehicle in the front-rear direction in the traveling direction at a detection frequency, and transmits distance information including the distance to the vehicle central controller 310. The vehicle central controller 310 compares the distance in the distance information with the first threshold distance. When the distance is less than the first threshold distance, the vehicle central controller 310 sends a first signal to the first output O1 coupled to the brake lights 340 that controls the brake lights 340 to be illuminated. The first threshold distance may be changed according to a vehicle speed, a road condition, and a weather condition. For example, the first threshold value may be 20 meters in the case of a speed of 20 km/h, and 60 meters in the case of a speed of 60 km/h. In addition, if the driver encounters strong wind, rain, snow, haze and the like, the front-rear distance of the vehicle should be properly increased due to unclear sight. The brake lamp 340 is lighted after receiving the lighting signal to prompt the rear vehicle to decelerate, so that the rear vehicle is prompted to decelerate when the vehicle where the sensor 320 is located is not braked, and the possibility of rear-end collision is reduced to a certain extent.
In still another embodiment of the present invention, the vehicle brake lamp control apparatus 300 includes a vehicle central controller 310, a sensor 320, and a logic determiner 360. Although shown as separate blocks in fig. 3, two or more of the vehicle central controller 310, the sensor 320, and the logic determiner 360 may be implemented together as a single element. The vehicle central controller 310 also has a second output directly coupled to the brake light 340 and configured to send a second signal to the second output controlling the brake light 340 to be turned on upon receiving a signal that the brake pedal 330 is depressed. The logic arbiter 360 has a first input I1 coupled to the sensor 320, a second input I2 coupled to the first output O1, and a fourth output O4 coupled directly to the brake light 340. When the vehicle travels forward, the sensor 320 coupled to the vehicle central controller 310 detects a distance between the vehicle in which it is located and another vehicle adjacent to the vehicle in the front-rear direction in the traveling direction at a detection frequency, and transmits distance information including the distance to the vehicle central controller 310. The vehicle central controller 310 compares the distance in the distance information with the first threshold distance. When the distance is less than the first threshold distance, the vehicle central controller 310 sends a first signal to the first output O1 that controls the brake lights 340 to be turned on. The first threshold distance may be changed according to a vehicle speed, a road condition, and a weather condition. For example, the first threshold value may be 20 meters in the case of a speed of 20 km/h, and 60 meters in the case of a speed of 60 km/h. In addition, if the driver encounters strong wind, rain, snow, haze and the like, the front-rear distance of the vehicle should be properly increased due to unclear sight. The logic determiner 360 is configured to send a third signal to the fourth output O4 to control the brake light 340 to be turned on when the distance information and the first signal from the sensor 320 are received at the same time. The brake lamp 340 is lighted after receiving the lighting signal to prompt the rear vehicle to decelerate, so that the rear vehicle is prompted to decelerate when the vehicle where the sensor 320 is located is not braked, and the occurrence of rear-end accidents is reduced to a certain extent.
Specifically, the logic determiner 360 receives the signal from the sensor 320 and the first signal from the vehicle central controller 310, and then outputs the signal from the sensor 320 and the first signal as a third signal to the brake lamp 340 after performing logic processing. When the logic determiner 360 determines that the distance received from the sensor 320 is less than the threshold distance while receiving the signal of the sensor 320, a third signal for controlling the turn-on of the brake lamp 340 is output from the fourth output terminal O4; and in the case where the logic determiner 360 does not receive any one of the sensor 320 signal and the first signal, it is recognized as a false determination so that the third signal for controlling the turn-on of the brake lamp 340 is not transmitted. By the logic determiner 360 causing the signal for controlling the turn-on of the brake lamp 340 to be sent via the first output O1 only in the case where it is confirmed that the sensor 320 detects the distance, misleading of the operation of the driver behind the host vehicle due to the turn-on of the brake lamp 340 by the erroneous determination by the vehicle center controller 310 when the sensor 320 signal is not received is avoided.
To implement the function that brake lamp 340 can be illuminated when either of the third signal and the second signal becomes a signal for controlling the illumination of brake lamp 340, the second signal and the third signal can be connected via a logical or device and then sent to brake lamp 340 as a signal for controlling brake lamp 340. However, this logical or means may also be physically located in the brake light, which controls the brake light to be lit upon receiving either of the second signal and the third signal, so as not to affect the normal operation of the brake light.
In the present invention, the vehicle where the sensor 320 is located may be referred to as a main vehicle, and the other vehicle may be an adjacent front vehicle or a rear vehicle that is located in the same traveling direction as the main vehicle. When it is detected that the vehicle behind the host vehicle is too close, the brake lamp 340 lights up, alerting the vehicle behind the host vehicle that it has been too close to the host vehicle, should slow down the vehicle speed and maintain sufficient headway. When the vehicle in front of the host vehicle is detected to be too close, the brake lamp 340 is lightened to prompt the vehicle behind the host vehicle that the host vehicle is likely to brake soon, the speed of the vehicle should be reduced, and the running distance between the vehicle and the host vehicle is increased so as to avoid rear-end collision when the front vehicle decelerates suddenly.
In another embodiment, a signal related to vehicle braking (e.g., a signal that the brake pedal 330 is depressed) is also coupled to the vehicle central controller 310. When the vehicle central controller 310 receives the signal of vehicle braking, it sends a second signal controlling the turning on of the brake lamp 340 to the second output O2 directly coupled to the brake lamp 340. Since the second signal is directly transmitted to the brake lamp 340, the brake lamp is turned on whenever the vehicle brakes in any case regardless of the comparison result of the distance detected by the sensor 320 with the first threshold distance. Therefore, the normal brake lamp 340 can be lightened without being influenced, and the rear vehicle is reminded to pay attention to deceleration and avoidance when the main vehicle carries out any braking action. In addition to the brake pedal 330, activation of a braking mode such as a hand brake, an electric brake button, etc. may also cause the vehicle central controller 310 to send a second signal to the second output O2 that controls the turning on of the brake lights 340.
In a further embodiment, the vehicle central controller 310 further has a third output O3 coupled to the speaker, and the vehicle central controller 310 is configured to compare the distance represented by the received distance information with a second threshold distance, and to send a fourth signal to said third output O3 controlling the turning on of the speaker 350 when the distance is less than the second threshold distance. Therefore, the driver is reminded to avoid obstacles around the vehicle body so as to prevent scratching the vehicle and even endangering surrounding pedestrians and self-safety. The second threshold distance is smaller than the first threshold distance, and may be, for example, 1 meter, 0.6 meter, 0.3 meter, 0.1 meter, or the like. Meanwhile, the speaker 350 may emit different beeps according to the distance included in the distance information. For example, this embodiment is mainly used when the vehicle is reversed, and the smaller the distance (the distance of the vehicle from the obstacle behind) included in the distance information is, the sharper the beep sound can be, to remind the driver of the different pitches.
According to a second aspect of the present invention, a vehicle brake light control system 400 is provided. In one embodiment, the vehicle brake light control system 400 includes any of the vehicle brake light control devices 300 according to embodiments of the present invention; and a brake light 340 configured to be illuminated upon receiving a signal controlling the illumination of the brake light 340.
In another embodiment, the vehicle brake light control system 400 further includes a brake pedal 330 configured to signal the vehicle central controller 310 that the brake pedal 330 is depressed when depressed. The vehicle central controller 310 sends a second signal for controlling the brake lamp 340 to be turned on to the second output terminal when receiving the signal that the brake pedal 330 is depressed.
In yet another embodiment, the vehicle brake light control system 310 further includes a speaker 350 configured to beep upon receiving a signal to turn the speaker on. The vehicle central controller 310 has a third output O3 coupled to the speaker and the vehicle central controller 310 is configured to compare the distance represented by the received distance information with a second threshold distance and to send a fourth signal to said third output O3 controlling the turning on of the speaker 350 when the distance is less than the second threshold distance. Therefore, the driver is reminded to avoid obstacles around the vehicle body so as to prevent scratching the vehicle and even endangering surrounding pedestrians and self-safety. The second threshold distance is smaller than the first threshold distance, and may be, for example, 1 meter, 0.6 meter, 0.3 meter, 0.1 meter, or the like. Meanwhile, the speaker 350 may emit different beeps according to the distance included in the distance information. For example, this embodiment is mainly used when the vehicle is reversed, and the smaller the distance (the distance of the vehicle from the obstacle behind) included in the distance information is, the sharper the beep sound can be, to remind the driver of the different pitches.
According to the third aspect of the utility model, a vehicle is provided, it includes vehicle brake lamp controlling means. When the vehicle runs forwards, if the distance between the front and rear vehicles and the vehicle is detected to be too small, the brake lamp can be actively lightened to prompt the rear vehicle to pay attention to deceleration and avoidance. When the vehicle is braked, the brake lamp can work normally to indicate that the vehicle behind keeps keeping the distance.
According to the fourth aspect of the utility model, a vehicle is provided, it includes vehicle brake lamp control system. When the vehicle runs forwards, if the distance between the front and rear vehicles and the vehicle is detected to be too small, the brake lamp can be actively lightened to prompt the rear vehicle to pay attention to deceleration and avoidance.
