Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. 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.
FIG. 1 is a block schematic diagram of a control system for a multiple light source headlamp according to an embodiment of the present invention.
As shown in fig. 1, a control system of a multi-light-source headlamp according to an embodiment of the present invention may include: an environment detection module 100, a first driving module 200, a second driving module 300, and a control module 400.
The environment detection module 100 is configured to detect current environment information of a vehicle; the control module 400 is connected to the environment detection module 100, the first driving module 200 and the second driving module 300, respectively, and the control module 400 is configured to determine whether current environment information of the vehicle meets a turn-on condition of the vehicle-mounted laser light, and when determining that the current environment information meets the turn-on condition of the vehicle-mounted laser light, control the first driving module 200 to turn on the vehicle-mounted laser light, and control the second driving module 300 to turn off the high beam light and the low beam light.
According to an embodiment of the present invention, as shown in fig. 2, the environment detection module 100 includes: the vehicle body control unit 110, the photosensitive detection unit 120, the haze detection unit 130 and the target detection unit 140 are respectively connected with the control module 400, wherein the vehicle body control unit 110 is used for detecting the current running speed of the vehicle; the photosensitive detection unit 120 is used for detecting the ambient light brightness of the current environment of the vehicle; the haze detection unit 130 is used for detecting the content of suspended particulate matters in the current environment of the vehicle; the object detection unit 140 is configured to detect whether an object person exists within a preset distance in front of the vehicle.
Specifically, the vehicle current environment information may include: the ambient light brightness of the current environment of vehicle, whether there is the target personage in the content of the suspended particulate matter and the preset distance in vehicle the place ahead in the current environment of vehicle, at the vehicle in-process of traveling, accessible automobile body the control unit 110 real-time detection vehicle current speed of traveling, and through the ambient light brightness of the current environment of vehicle of photosensitive detection unit 120 real-time detection, and through the content of the suspended particulate matter in the current environment of vehicle of haze detection unit 130 real-time detection, and whether there is the target personage in the preset distance in vehicle the place ahead through target detection unit 140 real-time detection. The vehicle body control unit 110 may include a vehicle speed sensor, the photosensitive detection unit 120 may include a photosensitive sensor, the haze detection unit 130 may include a smoke sensor, and the target detection unit 140 may include a millimeter wave radar.
The control module 400 is connected to the photosensitive detection unit 120 and the haze detection unit 130 through AD signal lines, respectively; the control module 400 is connected to the body control unit 110 and the object detection unit 140 through CAN buses, respectively.
According to an embodiment of the present invention, the control module 400 is specifically configured to: when the current running speed of the vehicle is identified and confirmed to be higher than the preset speed, the environmental brightness of the current environment of the vehicle is lower than the preset environmental brightness, the content of suspended particles in the current environment of the vehicle is lower than the preset content, and a target figure is not detected within the preset distance in front of the vehicle, the condition that the vehicle-mounted laser lamp is turned on is judged to be met.
Specifically, the control module 400 may compare the current running speed of the vehicle with a preset speed (e.g., 100km/h) after receiving the current running speed of the vehicle detected by the vehicle body control unit 110 through the CAN bus, and use that the current running speed of the vehicle is greater than the preset speed as one of the turn-on conditions of the on-board laser light (to improve accuracy, it may also be determined whether the current running speed of the vehicle is greater than the preset speed for a preset time, e.g., whether the duration is greater than 3 s); after receiving the ambient light brightness of the current environment of the vehicle detected by the photosensitive detection unit 110 through the AD signal line, the control module 400 may compare the ambient light brightness of the current environment of the vehicle with a preset ambient light brightness (e.g., 10lux), and set the ambient light brightness of the current environment of the vehicle smaller than the preset ambient light brightness as one of the turn-on conditions of the vehicle-mounted laser lamp; after receiving the content of the suspended particulate matter in the current environment of the vehicle detected by the haze detection unit 120 through the AD signal line, the control module 400 may compare the content of the suspended particulate matter in the current environment of the vehicle with a preset content, where it is considered that the particulate matter in the haze climate environment reflects light to a certain extent, and the on-board laser lamp has a high brightness, so that turning on the on-board laser lamp in the haze climate may easily cause visual dazzling interference to a driver of the vehicle and affect driving safety, and therefore, the content of the suspended particulate matter in the current environment of the vehicle may be smaller than the preset content (i.e., not in the haze weather) as one of the turning on conditions of the on-board laser lamp; the control module 400 may determine whether a target person exists within a preset distance (e.g., 300m ahead) in front of the vehicle according to the detection information after receiving the detection information of the target detection unit 130 through the CAN bus, and set one of the on-conditions of the on-vehicle laser lamp as the target person that is not detected within the preset distance in front of the vehicle. That is to say, when only satisfying above-mentioned condition simultaneously, the vehicle speed of traveling is greater than preset speed at present promptly, and the environment luminance of the current environment of vehicle is less than and predetermines the environment luminance, and the content of suspended particles thing is less than and predetermines the content in the current environment of vehicle, and when not detecting the target personage in the preset distance in vehicle the place ahead, judges the condition of opening that satisfies on-vehicle laser lamp, and at this moment, steerable on-vehicle laser lamp is lighted.
The control module 400 is connected to the first driving module 200 and the second driving module 300 through LIN buses, respectively. That is, when determining that the turn-on condition of the vehicle-mounted laser lamp is satisfied, the control module 400 may respectively send control instructions to the first driving module 200 and the second driving module 300 through the LIN bus to control the first driving module 200 so that the vehicle-mounted laser lamp is turned on, and control the second driving module 300 so that the high beam lamp and the low beam lamp are turned off.
Further, when the control module 400 determines that the on-state condition of the vehicle-mounted laser light is not satisfied, that is, the current driving speed of the vehicle is lower than a second preset speed (e.g., 90km/h), or the current ambient light brightness of the vehicle is higher than a second preset ambient light brightness (e.g., 30lux), or the current ambient light brightness of the vehicle is in a haze weather, or a target person is detected within a preset distance in front of the vehicle, control instructions may be respectively sent to the first driving module 200 and the second driving module 300 through the LIN bus, so that the first driving module 200 controls the vehicle-mounted laser light to be turned off, the second driving module 300 controls the high beam light and the low beam light correspondingly, and the fog light may be controlled correspondingly.
For example, when the current environment of the vehicle is in a haze weather, the control module 400 may send a control instruction to the first driving module 200 and the second driving module 300 through the LIN bus, so as to control the on-vehicle laser lamp to be turned off through the first driving module 200 and control the fog lamp to be turned on through the second driving module 300; when the current driving speed of the vehicle is less than the second preset speed, the control module 400 may respectively send control instructions to the first driving module 200 and the second driving module 300 through the LIN bus, so as to control the on-vehicle laser light to be turned off through the first driving module 200, and control the high beam light or the low beam light to be turned on through the second driving module 300.
From this, according to real-time driving operating mode, realize the automatic switch-over between the multiple light source module automatically, can intelligently control on-vehicle laser lamp effectively, for the driver automatically, better provide the night illumination, improve the security of driving.
Further, according to the above embodiment, in order to reduce the amount of data processing and increase the execution efficiency of the entire system, a progressive determination method is adopted in signal processing.
Specifically, as shown in fig. 3, after the system is powered on, initialization setting is performed on each sensor and each module, and whether the system operates within a normal operating voltage range is determined, and if not, fault detection is performed until it is determined that the system operates within the normal operating voltage range. Starting an internal timer, judging whether the control module 400 receives CAN message information, if not, judging whether the duration time of not receiving the CAN message information is more than 5s, if so, recording faults and giving an alarm, and at the moment, turning off the vehicle-mounted laser lamp; and if the CAN message information is received, judging whether the high beam needs to be controlled to be started or not. If the vehicle-mounted laser lamp is not needed, the vehicle-mounted laser lamp is controlled to be turned off, and if the vehicle-mounted laser lamp is needed, whether the vehicle running speed meets the starting condition or not is judged through the control module 400. If not, controlling the vehicle-mounted laser lamp to be turned off; if the preset speed is met, namely the running speed of the vehicle is continuously longer than the preset speed (for example, the running speed lasts for 3 seconds and is longer than 100km/h), further judging whether the environmental light brightness of the current environment of the vehicle meets the starting condition, and if the environmental light brightness does not meet the starting condition, controlling the vehicle-mounted laser lamp to be turned off; if the vehicle-mounted laser lamp meets the requirement, namely the environmental light brightness of the current environment of the vehicle is smaller than the preset environmental light brightness (for example, 10lux), further judging whether the current environment of the vehicle is in haze weather or not, and if so, controlling the vehicle-mounted laser lamp to be turned off; if not, further judging whether a target person (namely, other traffic participants) exists within a preset distance (for example, 300m ahead) in front of the vehicle, and if so, controlling the vehicle-mounted laser lamp to be turned off; and if the laser lamp does not exist, controlling the vehicle-mounted laser lamp to be turned on.
Therefore, the influence of factors such as the speed of the vehicle, the brightness of the environment, whether a target person exists in a preset range and the like is considered, the interference and the influence on a driver of the vehicle caused by starting the vehicle-mounted laser lamp in special weather environments such as haze and the like are also considered, and the actual use of the vehicle-mounted laser lamp is closer to the national conditions and humanization.
According to one embodiment of the present invention, the first driving module 200 and the second driving module 300 are connected to each other through a LIN bus.
Specifically, in an embodiment of the present invention, a communication line may be added between the first driving module 200 and the second driving module 300, so as to reduce the loss of function caused by communication failure between the control module 400 and the single-channel driving unit, eliminate potential safety hazards, and increase the robustness of the entire system.
In summary, according to the control system of the multi-light-source headlamp in the embodiment of the present invention, the environment detection module detects the current environment information of the vehicle, and the control module determines whether the current environment information of the vehicle meets the turn-on condition of the vehicle-mounted laser lamp, and when determining that the current environment information of the vehicle meets the turn-on condition of the vehicle-mounted laser lamp, the first driving module is controlled to turn on the vehicle-mounted laser lamp, and the second driving module is controlled to turn off the high beam and the low beam. Therefore, the vehicle-mounted laser lamp can be intelligently and effectively controlled by combining the current environment information of the vehicle, so that the safety and the reliability of the vehicle are greatly improved.
