Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
As shown in fig. 2, the present invention provides a method for automatically adjusting light of an automobile, comprising the following steps:
(1) the method comprises the following steps that a G sensor is installed inside a dimming control unit, and the dimming control unit collects and analyzes axial acceleration and angular velocity data of a vehicle, which are acquired by the G sensor;
(2) the dimming control unit acquires vehicle information, namely information such as the speed, the gear, the position of an accelerator pedal and the position of a brake pedal of the vehicle through a vehicle body bus, and identifies the state of the vehicle according to the vehicle information;
(3) the dimming control unit calculates the current locomotive inclination angle of the vehicle according to the axial acceleration data;
(4) and according to the state of the vehicle, the dimming control unit controls the dimming actuator to adjust the irradiation distance of the headlamp according to the tilt angle of the vehicle head and selectively according to the angular speed data.
According to the invention, the G sensor is additionally arranged in the dimming control unit, the G sensor is a chip capable of sensing the axial acceleration and the angular velocity of the vehicle, the processor in the dimming control unit acquires and analyzes the required axial acceleration and the required axial angular velocity, and converts the acquired axial acceleration and the angular velocity into the current locomotive inclination angle of the vehicle after calculation, and the dimming control unit controls the dimming actuating mechanism to realize the automatic adjustment of the light of the automobile headlamp according to the acquired current locomotive inclination angle of the vehicle. The invention has high dimming precision, cancels the mode of installing a height sensor on the automobile chassis in the traditional light adjusting method, does not need external equipment, saves an installation bracket and a wire harness, reduces the cost of the whole system, reduces the working procedure of the whole automobile assembly, is beneficial to reducing the weight of the automobile, avoids the risk of the failure of the whole system caused by the severe use environment of the automobile chassis, and simultaneously avoids the maintenance problem of the height sensor.
In the step (4), because the vehicle is in different change states in the running process, aiming at different states of the vehicle, the dimming control unit controls the dimming actuating mechanism to adjust the irradiation distance of the headlamp according to the tilt angle of the locomotive and selectively according to the angular speed data, thereby realizing a good automatic dimming function.
When the vehicle is stationary, gravity generates acceleration components in three axial directions of the G sensor, respectively. The change of the load of the vehicle body can cause the change of the inclination angle of the G sensor, and the acceleration component information of the gravity reflected by the G sensor in three axial directions can be correspondingly changed. At the moment, the vehicle is static, the G sensor is only under the action of gravity, so that the acceleration data reflected by the G sensor is a gravity acceleration component generated by gravity in a corresponding axial direction according to the inclination angle of the vehicle head, the current axial acceleration data is collected by a processor of the dimming control unit, then trigonometric function operation is carried out, the current vehicle head inclination angle of the vehicle can be obtained, and the dimming control unit controls the dimming execution mechanism to adjust the irradiation distance of the headlamp according to the vehicle head inclination angle, so that the automatic dimming function according to the load change of the vehicle body under the static condition is realized.
During the running of the vehicle, the G sensor is acted by the gravity and the body force, and the acceleration reflected by the G sensor is the result of the combined action of the gravity and the body force. The tilt angle of the head is changed continuously along with different road conditions, at the moment, the error of the tilt angle calculated according to the axial acceleration data of the G sensor is larger, the change amount of the angle in unit time can be calculated by means of the angular velocity information of the pitching axial direction of the G sensor to carry out auxiliary judgment, and the road condition can be identified by means of the information of the pitching angular velocity, so that the dynamic light adjustment effect is optimized, namely, the dimming control unit calculates the current tilt angle of the vehicle according to the axial acceleration data of the G sensor, calculates the change amount and the change trend of the tilt angle of the head according to the angular velocity data, identifies the road condition information according to the angular velocity data, and controls the dimming execution mechanism to adjust the irradiation distance of the head lamp according to the tilt angle, the change amount and the change trend of the tilt angle of the head and the road condition information, therefore, the automatic dimming function according to the load change of the vehicle body under the dynamic condition is realized.
Aiming at different running states and driving road conditions of the vehicle, the specific dimming method provided by the invention comprises the following steps:
when the automobile trunk is fully loaded in a static state, the head of the automobile is lifted, the short-distance illumination becomes large, and dazzling can be caused to a driver of a vehicle in front. The dimming control unit can recognize that the vehicle is in a static state according to the vehicle body bus information, calculate the current locomotive inclination angle according to the axial acceleration data of the G sensor, and then control the dimming actuating mechanism to adjust the short-distance light irradiation distance of the headlamp so as to shorten the short-distance light irradiation distance to a proper position, thereby avoiding dazzling of a driver of the vehicle in front.
When the automobile is stopped on a downhill slope, the gravity center moves forward, the head of the automobile is pressed down, the short-distance illumination becomes small, and the visual field of a driver becomes poor. The dimming control unit can calculate the current tilt angle of the head according to the axial acceleration data of the G sensor, and then controls the dimming actuating mechanism to adjust the low-beam irradiation distance of the headlamp to increase the low-beam irradiation distance to a proper position, so that the visual field of a driver is improved.
The automobile accelerates, the head of the automobile is lifted, and the short-distance illumination becomes larger. The dimming control unit can recognize that the automobile enters an acceleration state through the change condition of the position information of the accelerator pedal of the automobile acquired by the automobile body bus, starts to adjust the short-distance illumination distance in advance, calculates the current head dip angle according to the axial acceleration data of the G sensor, calculates the variation and trend of the head dip angle according to the angular velocity data, integrates the above information to realize the control of the short-distance illumination distance, and completes the ideal adjustment of the short-distance illumination distance in the acceleration process.
The automobile is braked, the gravity center moves forwards, the head of the automobile is pressed down, and the dipped beam illumination distance is reduced. The dimming control unit can recognize that the automobile enters a braking state through automobile brake pedal position information acquired by an automobile body bus, starts to adjust the short-distance illumination distance in advance, calculates the current locomotive inclination angle according to the axial acceleration data of the G sensor, calculates the variation and the variation trend of the locomotive inclination angle according to the angular velocity data, integrates the above information to realize the control of the short-distance illumination distance, and completes the ideal adjustment of the short-distance illumination distance in the braking process.
When the automobile goes up a slope, the head of the automobile is lifted, and the short-distance illumination becomes larger. The dimming control unit can recognize that the automobile enters an ascending slope according to the angular speed data of the G sensor, starts the dipped beam distance adjustment, can know the gradient according to the integral of the angular speed of the G sensor, and can calculate the gradient according to the axial acceleration data of the G sensor. Based on the information from the G sensor, the dimming control unit can recognize the state of the vehicle entering, traveling on a slope, and leaving the slope, and complete the adjustment of the low beam illumination distance in the state of the slope.
When the automobile descends, the head of the automobile is pressed down, and the short-distance illumination becomes smaller. The dimming control unit can recognize that the automobile enters the downhill according to the angular speed data of the G sensor, starts the dipped beam illumination distance adjustment, can know the gradient according to the integral of the angular speed of the G sensor, and can calculate the gradient according to the axial acceleration data of the G sensor. According to the G sensor information, the dimming control unit can recognize the states that the vehicle enters a downhill slope, runs on a slope and leaves the downhill slope, and completes the adjustment of the low beam illumination distance in the downhill slope state.
The adjustment of the low beam distance is performed relative to the reference inclination angle recorded in the dimming control unit, and because the reference inclination angles recorded in the dimming control units of different vehicles may be different due to the existence of installation errors, each vehicle needs to acquire and record the reference inclination angle when the vehicle is off-line, otherwise, the automatic dimming function is not started. The dimming control unit obtains and records a reference inclination angle, namely the dimming control unit calibrates a locomotive head reference inclination angle, and when the locomotive head inclination angle changes relative to the locomotive head reference inclination angle, the dimming control unit controls the dimming actuating mechanism to adjust the irradiation distance of the headlamp according to the locomotive head inclination angle.
The calibration method of the locomotive datum inclination angle specifically comprises the following steps:
(1) the vehicle is unloaded and placed on a horizontal road surface;
(2) activating the dimming control unit through a vehicle body bus to enter a calibration mode;
(3) the dimming control unit carries out filtering processing on the axial acceleration data of the vehicle acquired by the G sensor;
(4) the dimming control unit calculates and stores a locomotive datum inclination angle according to the axial acceleration data;
(5) and after calibration is completed, the dimming control unit starts an automatic dimming function.
