[0028] The technical solutions in the present application will be described in detail below with reference to the accompanying drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " represents the meaning of or, for example, A / B can represent A or B: "and / or" in the text only describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which means that there are three cases of A alone, A and B together, and B alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.
[0029] Hereinafter, the terms "first" and "second" are used only for descriptive purposes and cannot be understood as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined with "first" and "second" can explicitly or implicitly include one or more of the features.
[0030] The ALS system is a control system for vehicle headlamps, which aims to automatically adjust the illumination angle of the vehicle headlights according to the load of the vehicle, the driving state (such as acceleration, deceleration, turning, slope change, etc.) and the road conditions, so as to ensure that the vehicle headlights always illuminate the road at the correct angle, avoid the vehicle headlights from illuminating too high or too low due to changes in the vehicle body posture, and thus reduce glare to other road users, to improve driving safety and comfort.
[0031] The traditional ALS system usually relies on motor drive to adjust the illumination angle of the vehicle headlights. After detecting the change in the vehicle body posture, a certain time is needed to drive the motor to adjust the angle. This delay may cause the illumination angle of the vehicle headlights to be unable to adjust in time when the vehicle is accelerating, decelerating or encountering a bumpy road section, thereby affecting the lighting effect. At the same time, when the vehicle is driving on an uneven road, the vehicle body will bounce up and down, which will cause the illumination angle of the vehicle headlights to fluctuate frequently. The traditional ALS system cannot effectively filter these high-frequency vibrations, so that the illumination angle of the vehicle headlights is unstable, affecting the user's visual experience. Therefore, to solve the above problems, the present application combines the damper and the gyroscope, which can quickly respond to changes in the vehicle body posture and effectively filter the influence of road bumps, so that the light module can be accurately and quickly adjusted under different road conditions to ensure that the light module maintains the correct illumination angle, thereby improving the safety and comfort of driving.
[0032] Figure 1is a whole design schematic diagram of a light adjusting system of a vehicle provided by an embodiment of the present application.
[0033] As shown in the figure, Figure 1 The light adjusting system 10 of the vehicle includes a light device to be adjusted 100, a detection module 200, a damping device 300, a motion guiding module 400, a support 500 and a base 600.
[0034] As shown in the figure, Figure 1 and Figure 2 As shown in the figure, the light device to be adjusted 100 can include a light module and a light lens; the detection module 200 can be at least one of a gyroscope, a slope sensor and an acceleration sensor, used to detect the current driving state of the vehicle; the motion guiding module 400 can be a limited slip rail, connected to the light device to be adjusted 100, mainly including a first guiding unit 401 and a second guiding unit 402, the first guiding unit 401 being arranged above the light device to be adjusted 100, the second guiding unit 402 being arranged below the light device to be adjusted 100, used to adjust the sliding direction and sliding distance of the light device to be adjusted 100; the damping device 300 can be a damper, wherein the damping device 300 mainly includes a first damping unit 301 and a second damping unit 302, the first damping unit 301 being connected to the first guiding unit 401 and connected to the light device to be adjusted 100 through the first guiding unit 401, and connected to the detection module 200 through the base 600, the second damping unit 302 being connected to the second guiding unit 402 and connected to the light device to be adjusted 100 through the second guiding unit 402, and connected to the detection module 200 through the base 600, the damping device 300 adjusting the light device to be adjusted 100 based on the current driving state of the vehicle; the support 500 is arranged on the base 600.
[0035] Optionally, in an embodiment of the present application, the damping device 300 further includes an adjusting unit connected to the detection module, the first damping unit and the second damping unit respectively, the adjusting unit determining the first damping value and the second damping value according to the current driving state.
[0036] Specifically, in order to avoid that the vehicle causes the light irradiation angle to frequently fluctuate when the vehicle is rapidly accelerated, rapidly decelerated or encounters a bumpy road section, so that the light irradiation angle cannot be adjusted in time, thereby causing the light irradiation angle to be unstable, and further affecting the lighting effect and the visual experience of the user, the present application combines the damper and the gyroscope, so that it can quickly respond to the change of the vehicle body posture and effectively filter the influence of the road bump, thereby enabling the light module to be accurately and rapidly adjusted under different road conditions, so as to ensure that the light module maintains the correct irradiation angle, and further improve the safety and comfort of driving.
[0037] Specifically, as shown in the figure, Figure 3As shown, in order to stabilize the to-be-adjusted light device 100, the light irradiation angle of the vehicle lamp can be adjusted according to the current driving state of the vehicle, and the damping device 300 is added to the to-be-adjusted light device 100 in the embodiment of the application, the damping device 300 includes a first damping unit 301 and a second damping unit 302, that is, the damping device 300 includes two dampers, which are arranged above and below the to-be-adjusted light device 100 respectively, and meanwhile, the damping device 300 further includes an adjusting unit connected with the detection module, the first damping unit 301 and the second damping unit 302 respectively, for determining the first damping value and the second damping value according to the current driving state.
[0038] Firstly, the current driving state of the vehicle is detected by the detection module 200, mainly including the slope information of the vehicle, the acceleration information of the vehicle and the jolt information of the vehicle, for example, whether the slope information of the vehicle is greater than the preset slope threshold value is identified by the slope sensor, or whether the acceleration information of the vehicle is greater than the preset acceleration threshold value is identified by the acceleration sensor, or whether the vehicle is in the jolt state is identified by the gyroscope, if it is identified that the vehicle is not in the climbing road section, and the vehicle drives at a constant speed, and the vehicle drives on a smooth road section, at this time, it is indicated that the vehicle is in a normal driving state, the system maintains the default setting, and the to-be-adjusted light device 100 maintains a fixed angle of irradiation; if it is identified by the slope sensor that the slope information of the vehicle is greater than the preset slope threshold value, that is, the vehicle is in a non-horizontal road section, or it is identified by the acceleration sensor that the acceleration information of the vehicle is greater than the preset acceleration threshold value, that is, the vehicle is in an accelerated or decelerated driving state, or it is identified by the gyroscope that the vehicle is in a jolt state, at this time, the control system calculates the damping device 300, that is, the first damping value required by the first damping unit 301 and the second damping value required by the second damping unit 302, and generates a damping adjustment instruction based on the first damping value 301 and the second damping value 302 after being determined by the adjustment unit, to dynamically adjust the damping value according to the adjustment instruction, that is, when it is identified by the slope sensor that the slope information of the vehicle is greater than the preset slope threshold value, at this time, the control system calculates the first damping value and the second damping value under the current slope information of the vehicle, and adjusts the to-be-adjusted light device 100 by the first damping unit 301 and the second damping unit 302 according to the first damping value and the second damping value, or when it is identified by the acceleration sensor that the acceleration information of the vehicle is greater than the preset acceleration threshold value, at this time, the control system calculates the first damping value and the second damping value under the current acceleration information of the vehicle, and adjusts the to-be-adjusted light device 100 by the first damping unit 301 and the second damping unit 302 according to the first damping value and the second damping value, or when it is identified by the gyroscope that the vehicle is currently in an uneven road section, at this time, the control system calculates the first damping value and the second damping value under the current uneven road section of the vehicle, and adjusts the to-be-adjusted light device 100 by the first damping unit 301 and the second damping unit 302 according to the first damping value and the second damping value, so that the damper can adjust the to-be-adjusted light device 100 according to the damping value calculated in real time when the attitude information of the vehicle changes for a long time or instantaneously, and at the same time, the damper can effectively filter out high-frequency vibrations caused by uneven road surfaces when adjusting the to-be-adjusted light device 100, effectively filter the jolt road section, to avoid producing glare and affecting the driving safety of the user.
[0039] The preset slope threshold, the preset acceleration threshold and the preset slope threshold can be set by a person skilled in the art according to actual test requirements, or can be obtained through a limited number of computer simulations, and are not limited herein.
[0040] Thus, by dynamically adjusting the damping value, the damper can effectively absorb high-frequency and low-frequency vibrations, thereby reducing the jitter of the light device 100 to be adjusted, ensuring that it can maintain smooth movement under various driving conditions, not only improving the stability of the light, but also prolonging the service life of the entire system.
[0041] For example, when the vehicle is driving on a slope, the slope sensor detects the change in the angle of the body leaning forward or backward, at which time the control system calculates the first damping value required by the first damping unit 301 and the second damping value required by the second damping unit 302, respectively, and generates a damping adjustment instruction based on the first damping value and the second damping value, to adjust the damping value according to the adjustment instruction, and to adjust the light device 100 to be adjusted by the first damping unit 301 and the second damping unit 302 according to the first damping value and the second damping value, so that the light device 100 to be adjusted can automatically adjust with the change in the inclination angle of the body, to ensure that the light always shines on the road.
[0042] Further, when the vehicle is in rapid acceleration or deceleration, the body will tilt forward and backward, and the acceleration sensor can identify this change, at which time the control system calculates the first damping value required by the first damping unit 301 and the second damping value required by the second damping unit 302, respectively, and generates a damping adjustment instruction based on the first damping value and the second damping value, to adjust the damping value according to the adjustment instruction, and to adjust the light device 100 to be adjusted by the first damping unit 301 and the second damping unit 302 according to the first damping value and the second damping value, so as to ensure that the light device 100 to be adjusted always maintains the correct illumination angle.
[0043] Further, when the vehicle is driving on an uneven road section, the gyroscope detects the up-and-down bouncing of the body, at which time the control system calculates the first damping value and the second damping value of the vehicle under the current uneven road section, and adjusts the light device 100 to be adjusted by the first damping unit 301 and the second damping unit 302 according to the first damping value and the second damping value, while filtering out high-frequency vibrations, to ensure that the light device 100 to be adjusted can move smoothly and maintain a stable lighting effect.
[0044] Secondly, in order to avoid the to-be-adjusted light device 100 from adjusting beyond the set range or deviating from the track, the motion guide module 400, i.e., the slide limiting rail, is additionally added to limit the sliding direction and sliding distance of the to-be-adjusted light device 100. The slide limiting rail of the embodiment of the application includes the first guide unit 401 and the second guide unit 402. The first guide unit 401 is arranged above the to-be-adjusted light device 100, and the second guide unit 402 is arranged below the to-be-adjusted light device 100. Both the first guide unit 401 and the second guide unit 402 are connected with the to-be-adjusted light device 100. After the damping value of the to-be-adjusted light device 100 is calculated, the first guide unit 401 and the second guide unit 402 control the to-be-adjusted light device 100 to move in the set direction and distance based on the damping value, so as to provide a stable adjustment path for the to-be-adjusted light device 100, to ensure that the to-be-adjusted light device 100 can move smoothly in the set direction and distance. At the same time, by limiting the moving range of the to-be-adjusted light device 100, the protection of the damper is also achieved.
[0045] Finally, the to-be-adjusted light device 100 can also be optimized by collecting other driving information such as vehicle speed information and steering angle information. For example, the response speed and adjustment amplitude of the to-be-adjusted light device 100 are optimized based on the vehicle speed information, and the angle of the to-be-adjusted light device 100 is optimized based on the steering angle information, i.e., the angle of the to-be-adjusted light device 100 is adjusted in advance, so as to obtain the vehicle light irradiation angle based on the optimized to-be-adjusted light device 100. At the same time, based on the obtained vehicle light irradiation angle, it is judged whether the vehicle light irradiation angle meets the vehicle light irradiation standard, i.e., whether the vehicle light irradiation angle has deviation. If the vehicle light irradiation angle does not meet the vehicle light irradiation standard, i.e., the vehicle light irradiation angle has deviation, the vehicle light irradiation angle can be adaptively corrected based on the current driving state of the vehicle, so as to further ensure that the to-be-adjusted light device 100 always irradiates at the correct irradiation angle.
[0046] Therefore, based on the above-mentioned light adjustment system of the vehicle, the embodiment of the application can achieve the following beneficial effects:
[0047] (1) Improve light stability: The inclination angle, acceleration and other information of the vehicle are monitored in real time by the detection modules such as the gyroscope, the slope sensor and the acceleration sensor. The control system can quickly respond to the change of the vehicle body posture to ensure that the to-be-adjusted light device always irradiates the road surface at the correct angle. At the same time, the damper dynamically adjusts its damping value according to the damping adjustment instruction, absorbs vibration energy, and reduces the shaking of the to-be-adjusted light device, so as to ensure that the light irradiation is more stable.
[0048] (2) Precise motion guidance: The application provides a precise motion path for the light device to be adjusted through the limited slip rail, ensuring that it can freely slide in the set direction and follow the changes in the vehicle's attitude, maintaining stable lighting effects;
[0049] (3) Self-adaptive filtering: The application embodiment can perform self-adaptive filtering according to vibrations of different frequencies and amplitudes by adjusting the damping value of the damper, ensuring that the light device to be adjusted can maintain optimal stability and response speed under various driving conditions;
[0050] (4) Real-time feedback and correction: The control system monitors the current driving state of the vehicle in real time through the sensor and further corrects according to the feedback data to ensure that the light device to be adjusted always maintains the correct illumination angle.
[0051] In summary, according to the light adjustment system of the vehicle of the application, the light device to be adjusted is used to detect the current driving state of the vehicle, the damping device is connected to the light device to be adjusted and the detection module, and the damping device adjusts the light device to be adjusted based on the current driving state of the vehicle. The system combines the damper and the gyroscope to quickly respond to changes in the vehicle's attitude, effectively filter the influence of road bumps, and accurately and quickly adjust the light module under different road conditions to ensure that the light module maintains the correct illumination angle, thereby improving the safety and comfort of driving.
[0052] Further, the application provides a vehicle comprising the above-mentioned light adjustment system of the vehicle, which combines the damper and the gyroscope to quickly respond to changes in the vehicle's attitude, effectively filter the influence of road bumps, and accurately and quickly adjust the light module under different road conditions to ensure that the light module maintains the correct illumination angle, thereby improving the safety and comfort of driving.
