Detailed Description
the following detailed description of the present invention is provided in conjunction with the accompanying drawings, and it is to be understood that the detailed description set forth herein is merely illustrative and explanatory of the invention and is not restrictive thereof.
As shown in fig. 1 to 3, the present invention provides a method for controlling an adaptive steering lamp body 100. In order to facilitate the rider to use the lamp body 100, the various components are mounted and arranged, and then the adaptive steering function of the lamp body 100 is realized through the following steps.
The invention provides a control method of a self-adaptive steering lamp, which particularly realizes the irradiation posture of a lamp body 100 from the following steps:
s1: analyzing the current state of the car lamp mounting seat according to the inclination angle between the car lamp mounting seat and the horizontal plane; specifically, the controller 200 determines the current state of the lamp mounting base according to the inclination angle generated with the horizontal plane measured by the inclination angle detecting means. The lamp mounting base is used for fixedly mounting and connecting the lamp body 100 and the vehicle.
S2: if the car lamp mounting seat is in an inclined state, detecting the roll angle, the forward tilt angle and the running speed of the current car lamp mounting seat and the horizontal plane, and driving the car lamp body 100 to make a spatial attitude change relative to the car lamp mounting seat by controlling the driving mechanism 300, so that the irradiation direction of the car lamp body 100 deflects towards the inner side of a curve, the car lamp body 100 makes roll angle compensation rotation relative to the car lamp mounting seat, and/or the irradiation direction of the car lamp body 100 makes forward tilt angle compensation deflection relative to the forward tilt angle of the car lamp mounting seat.
Specifically, the controller 200 measures the current vehicle lamp mount attitude, i.e., the roll angle θ and/or the forward angle β with the horizontal plane, based on the inclination angle detection means 400, and further measures the current traveling speed v based on the speed detection means 500; the controller 200 controls the driving mechanism 30 to perform corresponding driving measures according to the roll angle θ, the forward tilt angle β and the traveling speed v of the lamp mounting base, and further drives the output ends of the first motor 311, the second motor 312 and the third motor 313 to move.
and controlling the vehicle lamp body 100 to make a roll angle theta compensation rotation theta angle relative to the vehicle lamp mounting base according to the roll angle theta of the current vehicle lamp mounting base. Specifically, because the car light body 100 is rotated in the car light mount pad is taken along when the slope, car light body 100 is because the light type structure of the illumination of car light body 100 when rotating, make the distance light be in the top, thereby cause the vertigo for the pedestrian of opposite side easily, cause the accident, consequently through car light body 100 to the bend outside rotation theta angle, the relative car light mount pad of car light body 100 makes the roll angle theta compensation rotation promptly, resume to the gesture of shining of car light body 100 under normal condition, the passing beam shines in the top of distance light promptly, thereby avoid because turn to the accident hidden danger that causes.
in the present embodiment, the specific steps of deflecting the irradiation direction of the lamp body 100 toward the inside of the curve are as follows:
s21: the turning radius r calculated according to the roll angle theta and the running speed v of the current vehicle lamp mounting seat is as follows:
By: f ═ m × v2/r (1)；
F＝m*g/tanθ (2)；
To give, r ═ tan θ v2/g (3)；
wherein m is the mass of the vehicle, g is the gravitational acceleration, and F is the centripetal force;
S22: calculating an angular velocity ω, ω -v/r (4) when the lamp mounting seat turns, from the turning radius r and the running speed v in S21;
S23: calculating an included angle between the required irradiation direction of the lamp body 100 and the forward direction of the steering of the lamp mounting seat as alpha according to the angular velocity omega during turning and a preset duration n in the step S22, wherein the included angle is alpha, and alpha is n omega/2 (5);
As shown in fig. 2, the included angle at the inner side of the curve is the required irradiation direction of the vehicle lamp body 100;
s24: and according to the included angle alpha between the required irradiation direction of the lamp light source part and the steering advancing direction of the lamp mounting seat in the S23, controlling the lamp light source part to deflect at the angle alpha relative to the inner side of the curve of the lamp mounting seat.
According to the forward inclination angle beta of the current vehicle lamp mounting seat, the forward inclination of the vehicle lamp body 100 relative to the vehicle lamp mounting seat is controlled to make a compensation angle beta of the reverse forward inclination angle beta. Specifically, for example, when the vehicle runs on a slope or a bumpy road, the lamp mounting base tilts up and down along with the rise and fall of the road, so that the irradiation direction of the lamp body 100 is changed. When the vehicle lamp body 100 is obliquely irradiated upwards, the head-on pedestrian can be dazzled, so that an accident is caused; when the lamp body 100 is inclined downward, the direction of illumination of the lamp body 100 does not facilitate the rider to observe the road, thereby easily causing the rider to cause an accident. Therefore, when going up or down a slope or on a bumpy road, the control lamp body 100 can compensate the front end up-down inclination angle β.
in one embodiment, the lamp mount is fixed to the front end of the vehicle body, in this case, the lamp mount is fixed to the vehicle beam. It can be understood that when the lamp body 100 is disposed on the vehicle body, the lamp body 100 changes with the change of the vehicle body. The controller 200 receives the inclination angle detection device 400 to measure the side angle and the front inclination angle of the vehicle body and the horizontal direction in the riding process; the controller 200 receives the speed detection device 500 to measure the driving speed during riding; the controller 200 controls the irradiation direction of the car lamp body 100 to deflect on the horizontal plane according to the roll angle and the speed of the car body, controls the driving mechanism 300 to drive the car lamp body 100 to rotate in a compensation mode relative to the roll angle of the car lamp mounting seat according to the roll angle of the car body, and controls the driving mechanism 300 to drive the car lamp body 100 to deflect in a compensation mode in the vertical direction according to the front rake angle of the car body, so that a rider can clearly observe the road condition of a target road in the riding process, and riding safety is improved.
In another embodiment, when the lamp body 100 is mounted on the head of the vehicle, the lamp changes with the change of the head of the vehicle. The controller 200 receives the inclination angle detection device 400 to measure the side angle and the front inclination angle of the bicycle head and the horizontal direction in the riding process; the controller 200 receives the speed detection device 500 to measure the driving speed during riding; the controller 200 controls the irradiation direction of the car lamp body 100 to deflect on the horizontal plane according to the roll angle and the speed of the car head, controls the driving mechanism 300 to drive the car lamp body 100 to rotate in a compensation mode relative to the roll angle of the car head according to the roll angle of the car head, and controls the driving mechanism 300 to drive the car lamp body 100 to deflect in a compensation mode in the vertical direction according to the front rake angle of the car head, so that a rider can clearly observe the road condition of a target road in the riding process, and riding safety is improved.
further, according to the above method, the control device of the adaptive steering lamp body 100 provided by the present invention specifically includes, as shown in fig. 1-2, a controller 200, a driving mechanism 300, an inclination angle detection device 400, and a speed detection device 500. The driving mechanism 300 is connected to the controller 200 and the lamp body 100, and the driving mechanism 300 is used to fixedly mount the lamp 10, so that the controller 200 controls the driving mechanism 300 to drive the lamp 100 to make a spatial attitude change with respect to the lamp mount. Generally, turn to in the process of riding and realize through removing the focus from the front rear wheel focus line to the bend inboard, need be through to the inboard dump car lamp mount pad of bend under the general condition for realize the purpose of turning through the car light mount pad of inclining, car light mount pad fixed mounting is usually in automobile body or locomotive, and when the car light mount pad was fixed in the locomotive, the turned angle of locomotive was less than the circular arc that actually turns to. When the lamp mount is fixed to the vehicle body, the resulting irradiation direction of the lamp body during steering is greatly different from the viewing direction of the rider. In addition, when the vehicle runs on a slope or a bumpy road, the front end of the vehicle lamp mounting seat inclines upwards or downwards along with the fluctuation of the road, so that the irradiation direction of the vehicle lamp body is different from the observation direction of a rider, and safety accidents are easy to happen. Therefore, the present invention provides an adaptive steering lamp control device for mounting the lamp body 100.
Further, the device also comprises a control keyboard 600. The control keyboard 600 is connected to the controller 200, and is used for inputting the relevant parameters of the vehicle lamp body 100 on the control keyboard 600, so that the controller 200 executes the corresponding operation according to the input relevant parameters. Specifically, several pre-made parameters of the vehicle lamp body 100 may be input on the control keyboard 600. For example, because the high specification of car light mount pad is different, the initial setting requirement of different riders to car light body 100 is different at the in-process of riding, for example, sets for the initial height of a car light through control keyboard 600 to satisfy the riders of different needs, and then improve the security of riders at the in-process of riding. For example, when the lamp body 100 is mounted on the lamp mounting seat and the lamp mounting seat is fixedly mounted on the vehicle body or the vehicle head, the rotation angle of the lamp body 100 is different, and the lamp body or the vehicle head needs to be set in advance. In addition, the irradiation angle position of the vehicle lamp body 100 can be set, and the irradiation direction of the vehicle lamp body 100 can be regulated to any position from near to far according to the requirement of a rider; in addition, since the speed during riding is always in a changing state, the fixed time length n is required to be set by controlling the rotation of the lamp body 100, and is set by the control keyboard 600, which is not very long.
in order to adapt to the traditional vehicle type, the control device is set to a fixed mode and an adaptive mode, wherein the fixed mode is consistent with the traditional vehicle lamp mode, and the adaptive mode is the technical point to be described in the invention. The control keyboard 600 sends a control signal to the controller 200 to realize the turning on or off of the adaptive steering function of the device. When the adaptive function is turned off, the lamp body 100 is fixed to the lamp mount base as is conventional; the conventional car light body is disposed at the front end of the car body or the car head, and the driving mechanism 300 of the device is also mounted at the front end of the car body or the car head. When the adaptive function is turned on, the lamp body 100 has an adaptive steering function, and of course, the mode selection is based on the rider's needs, and it is generally preferable to turn on the adaptive steering function for safety reasons when the light is dim. In addition, the control keypad 600 may also transmit an instruction to the controller 200 to control the turning on and off of the lamp body 100. Further, the control keyboard 600 may also be dynamically calibrated to allow the rider to use the vehicle light of the present invention more safely and conveniently.
Further, as shown in fig. 4-5, in the present application, the driving mechanism 30 is a cradle head for installing the car light 10, and correspondingly, the position of the cradle head is consistent with that of the conventional car light, and the cradle head is fixedly installed on the car light installation seat, which is arranged at the front end of the car body or on the car head, and is adapted to the position of the car light in the common car type. The holder comprises a first motor 311, a second motor 312 and a third motor 313; the first motor 311, the second motor 312, and the third motor 313 are respectively connected to the controller 200, so that the controller 200 can simultaneously control the first motor 311, the second motor 312, and the third motor 313. Specifically, the controller 200 drives the first motor 311 to rotate according to the roll angle θ between the vehicle lamp mounting seat and the horizontal plane and the current speed v, so as to drive the irradiation direction of the vehicle lamp body 100 to deflect horizontally relative to the vehicle lamp mounting seat; the controller 200 drives the second motor 312 to rotate according to the forward inclination angle between the vehicle lamp mounting seat and the horizontal plane, so as to drive the irradiation direction of the vehicle lamp body 100 to make vertical compensation deflection relative to the vehicle lamp mounting seat; the controller 200 drives the third motor 313 to rotate according to the inclination angle of the lamp mounting base relative to the horizontal plane, so as to drive the irradiation direction of the lamp body 100 to rotate in a compensation manner relative to the inclination angle of the lamp mounting base.
in summary, controlling the car light body 100 to change the spatial attitude relative to the car light mounting seat includes: the controller 200 controls the car lamp body 100 to perform roll angle compensation relative to the car lamp mounting base according to the roll angle of the car lamp mounting base; the controller 200 controls the vehicle lamp body 100 to perform the front rake compensation relative to the vehicle lamp mounting base according to the front rake of the vehicle lamp mounting base; the controller 200 controls the lamp body 100 to deflect toward the inside of the curve with respect to the lamp mounting base according to the roll angle and speed of the lamp mounting base.
In this example, the pan-tilt adopts a three-axis pan-tilt, and the three motors in different directions of the pan-tilt are controlled to drive the control of the car light body 100.
in one embodiment, as shown in fig. 6, the head further comprises a first connecting arm 321 and a second connecting arm 322. The first connecting arm 321 connects the first motor 311 and the third motor 313, and the second connecting arm 322 connects the first motor 311 and the second motor 312. The controller 200 controls the first motor 311 to drive the first connecting arm 321 to rotate in the horizontal plane direction, so that the first connecting arm 321 drives the car lamp body 100 to rotate in the horizontal plane direction, thereby driving the deflection change of the irradiation direction of the car lamp body 100 in the horizontal direction relative to the car lamp mounting seat; the controller controls the second motor 312 to drive the second connecting arm 322 to rotate in the vertical plane direction, so as to drive the irradiation direction of the vehicle lamp body 100 to change in a deflection in the vertical direction relative to the vehicle lamp mounting seat; the controller 200 controls the third motor 313 to rotate, and since the third motor 313 is directly connected to the lamp body 100, the third motor 313 directly drives the lamp body 100 to rotate after rotating, thereby driving the lamp body 100 to rotate for compensating the roll angle of the lamp mounting base.
Of course, in the present embodiment, the lamp cover 700 is disposed outside the lamp body 100, and after the lamp cover 700 and the lamp body 100 are processed and integrated, the lamp cover 700 is fixedly connected and mounted on the holder, and further, the change of the irradiation direction of the lamp body 100 is controlled by controlling the posture change of the lamp cover 700.
Further, after the rider sends a start signal instruction to the controller 200 through the control keyboard 600, the device starts and adjusts the vehicle lamp body 100 to the optimal posture according to the signal instruction sent by the control keyboard 600, and then real-time monitoring is performed during driving. Specifically, the controller 200 controls the second motor 312 to rotate during riding to maintain the lamp body 100 in an optimal position with respect to the vertical direction; in a turning state, the controller 200 controls the first motor 311 to rotate to drive the first connecting arm 321 to rotate in a horizontal plane, so that the irradiation direction of the vehicle lamp body 100 is horizontally deflected; the controller 200 controls the third motor 313 to rotate to compensate for the angle of the lamp-mount-side inclination, i.e., to rotate the lamp body 100 outward of the curve. Further, because the light type characteristic of shining in the car light body 100, can divide the light type of shining into the but high beam of low beam, the low beam belongs to and is close to the short-beam, and the high beam belongs to long light, for safe riding, the low beam setting is in the top of high beam usually. After the car light mount pad slope, the high beam position is gone up and is changeed, and the high beam is direct to shine above, if the place ahead has someone, then shine to the place ahead personnel when the high beam, easily causes dizzy to the people, and easily causes traffic accident. Therefore, the controller 200 drives the third motor 313 to rotate, so as to drive the vehicle lamp body 100 to rotate in a compensation manner relative to the roll angle of the vehicle lamp mounting seat, thereby offsetting the roll angle of the vehicle lamp mounting seat, so that the low beam is always positioned above the high beam.
When going up and down a slope or being in a bumpy state, the front end of the vehicle lamp mounting seat is enabled to be in an upward-inclining or downward-inclining state, the controller 200 controls the second motor 312 to rotate in the vertical direction to drive the vertical surface of the second connecting arm 322 to rotate, so that the vehicle lamp body 100 is driven to generate vertical direction displacement change, the controller 200 controls the rotating angle of the second motor 312 to be the compensation angle for upward or downward inclining of the vehicle lamp mounting seat, and the irradiation direction of the vehicle lamp body 100 is driven to be in forward inclination angle compensation deflection.
