[0002] With the advancement of modern technology and the improvement of various traffic laws and regulations, there has been a social consensus on the harmfulness of fatigue driving and illegal driving. However, the current research on fatigue driving and illegal driving is far from reaching the level of data support. The current characterization and analysis of fatigue driving and illegal driving is still in the stage of hazard assessment and data statistics after a traffic accident occurs.
[0003] Moreover, with the advancement of technology in the automotive industry, the traditional vehicle testing, which requires real vehicle external scene testing, has been gradually replaced by testing in indoor simulated environments, thereby reducing the risk of many uncontrollable factors in the external environment and random events affecting the test results. It is mainly for the whole vehicle ambient light simulation, and for some functional tests, it is necessary to spend a huge amount of money to build a whole vehicle light environment. Atlas Custom Systems has a whole vehicle sunlight simulation solution, which is a gantry or ceiling fixed structure, with a large number of light sources and expensive prices. The current all-round lighting method used in automotive environmental laboratories, first of all, has extremely high power consumption, and has strict requirements for the power supply of conventional buildings or factories; secondly, the number of light sources is huge, and the laboratory space must be large enough, and conventional buildings cannot meet its space requirements; thirdly, its engineering cost is extremely high, and medium-sized and smaller enterprises cannot afford the expensive cost.

[0052] Below, the present disclosure is combined with the attached Figure 1 Let me explain.
[0053] [Overall system framework]
[0054] See also Figure 1One aspect of the present invention relates to a driving behavior monitoring and testing system that endangers driving safety, including a car driving simulator, a dynamic platform, a solar simulator, an assisted driving detector, and a central integrated measurement and control system; the dynamic platform drives the car driving simulator to simulate the movement posture of various road terrains; the solar simulator simulates the sunlight environment, and performs height-adjustable, angle-adjustable, and irradiation power-adjustable surround lighting on the car driving simulator; the assisted driving detector captures the driver's dangerous actions that endanger driving safety in the car driving simulator, and gives corresponding voice reminders; the central integrated measurement and control system integrates the functions of each module of the car driving simulator, the dynamic platform, the solar simulator, and the assisted driving detector, and can control each module synchronously in real time.
[0055] Optionally, the driving behavior endangering driving safety monitoring and testing system also includes a voice recognition module, which detects the voice broadcast content of the auxiliary driving detector in an online or offline manner and can provide real-time feedback on the detection result.
[0056] Among them, the central integrated measurement and control system mainly includes a central control host for controlling the above-mentioned modules. The central control host synchronously controls the above-mentioned vehicle driving simulator, dynamic platform, solar simulator, assisted driving detector and voice recognition module.
[0057] Among them, preferably, the car driving simulator can be modified with the front of a real car model, using advanced three-dimensional simulation technology, and the dynamic platform can use a six-degree-of-freedom motion platform, which is driven by a six-degree-of-freedom electric cylinder to drive the front chassis, thereby directly driving the front movement, and can read the force feedback data during driving in real time, and dynamically reflect the data to the driver, which can realize the centrifugal force of the real car, push back, shake, bump, and restore the state of various road conditions, so that the driver can feel in the cockpit and experience the visual and tactile impact brought by various road conditions when driving. The six-degree-of-freedom motion platform can simulate the motion posture of various road terrains by simulating the translation and rotation of objects in three directions, namely, front and rear translation, left and right translation, up and down vertical movement, pitch, roll and yaw and compound movement.
[0058] Optionally, the car driving simulator is not a must-have device. Instead of a car driving simulator, any other suitable device can be used as long as it can meet the needs of driving behavior detection testing. For example, a dynamic platform can simulate the motion posture of various road terrains and directly feed it back to the driver, and then other modules can perform the same detection and analysis.
[0059] The solar simulator uses a 2*2 array of metal halide lamps to simulate the sunlight environment. It has 360° surround lighting for car driving simulators, adjustable irradiation height from 1000mm to 2200mm above the ground, adjustable irradiation angle from 0 to 45°, and adjustable irradiation power from 50% to 100%.
[0060] The assisted driving detector can capture the driver's dangerous actions that endanger driving safety through infrared and give corresponding voice reminders. It also has ADAS functions and can broadcast warning information on driving conditions such as pedestrians in the lane, illegal lane changes, and beware of collisions. Optionally, the assisted driving detector is an ADAS assisted driving product.
[0061] The voice recognition module detects the voice broadcast content of the assisted driving detector in an online / offline manner, and can achieve 98% accuracy and a delay of less than 800ms with or without a network, and can provide real-time feedback on the detection results. Optionally, a protocol recognition module can be used instead of a voice recognition module to recognize the alarm information of the assisted driving detector.
[0062] Preferably, it may also include a projector and a circular projection wall (see Figure 1 ); The annular projection wall is set in front of the car driving simulator, and the road conditions from the first perspective of the vehicle are projected by the projector. Then the dynamic platform drives the car driving simulator to move according to the road conditions to simulate the movement postures of various road terrains.
[0063] Preferably, see Figure 1 It may also include control devices such as wired touch screens, IPAD devices connected via wireless routing, laptop computers, desktop computers or voice control devices to control the central control host.
[0064] Preferably, the driving behavior monitoring test method that endangers driving safety may include the following forms:
[0065] 1. Set the car driving simulator to the automatic driving mode. The three-channel projector projects the road information onto the circular projection wall. The dynamic platform provides real-time feedback on the physical presence of the vehicle driver during the vehicle's driving process. 2. Set the solar simulator to be linked with the scene to simulate the sunlight under the current road conditions. 3. Turn on the assisted driving detector. 4. The driver drives continuously for a certain period of time. 5. Voice (or protocol) recognizes the alarm information of the assisted driving detector. 6. The system conducts statistical analysis on the driver's fatigue driving and driving safety according to the number of dangerous alarms, collisions or accidents in the simulator. It can also test the dangerous actions of the driver that endanger driving safety during continuous driving, such as yawning, blinking, looking around, making phone calls, smoking, and taking both hands off the steering wheel, and make statistical analysis.
[0066] The various specific devices used in the above methods are exemplary and are not to be considered as limiting the scope of protection of the present disclosure.
[0067] The driving behavior monitoring and testing method endangering driving safety disclosed in the present invention is mainly used for indoor detection, and of course can also be used for outdoor detection.
[0068] [Solar Simulator 2000]
[0069] See also Figure 2-6 , respectively showing the overall structural diagram of the solar simulator 2000 device according to the contents disclosed in the present invention, the partial structural diagram of the lighting source 2100 and its angle bracket 2200, the partial structural diagram of the lifting bracket 2600 and the chassis 2800, the schematic layout of each module in the chassis 2800, the rail car 2910 and the partial structural diagram of the track.
[0070] Reference Figure 2-6 The solar simulator 2000 device includes an illumination light source 2100, an electronic ballast 2810, a lifting cylinder 2700, a lifting bracket 2600, an angle cylinder 2300, an angle bracket 2200, a servo control unit 2820, a control host 2850, and a power supply system 2860.
[0071] For details, see Figure 2 The solar simulator 2000 device is composed of, from bottom to top: a circular track 2920, which may optionally be an arc track; a rail car 2910 located on the circular track 2920; a chassis located on the rail car 2910, in which modules such as an electronic ballast 2810, a servo control unit 2820, a control host 2850 and a power supply system 2860 are integrated; a lifting bracket 2600 and a lifting electric cylinder 2700 located on the chassis; a lighting source base 2500 located on the lifting bracket 2600; a triangular bracket 2400 and an angle electric cylinder 2300 located on the lighting source base 2500; an angle bracket 2200 rotatably connected to the top of the triangular bracket 2400; and a lighting source 2100 mounted on the angle bracket 2200.
[0072] See also Figure 3, the lighting source 2100 is composed of 4 groups of xenon lamps or metal halide lamps. The parameters such as its light intensity are controlled by an electronic ballast 2810, which can more realistically simulate the outdoor sunlight illumination spectrum and light intensity. The high-power xenon lamp (or metal halide lamp) lamp array is used as the irradiation source, with a spectral distribution and illumination intensity closer to sunlight. Among them, the angle bracket 2200 includes a main structure in the shape of a cross and two "<" shaped structures 2220; the 4 groups of xenon lamps or metal halide lamps are respectively fixed in the cross-shaped structure 2210, and can be fixed to the inner side of the cross-shaped structure 2210 by conventional fixing methods such as welding, riveting, and screws; the main structure of the angle bracket 2200 can be spliced with materials having a certain hardness or integrally formed; on the left and right sides of the middle of the cross-shaped structure 2210, two "<" shaped structures 2220 are respectively formed backward (in the direction opposite to the light emitting direction of the light source), and each "<" shaped structure 2220 is hinged and fixed to one end of one of the two angle electric cylinders 2300; the lower end of each "<" shaped structure 2220 is fixedly connected to the joint of the "cross-shaped" structure and the "square-shaped" structure on the left and right sides of the middle of the cross-shaped structure 2210, and the upper end of each "<" shaped structure 2220 is fixed at a position on the left and right sides of the cross-shaped structure 2210, about one-third of the side length of the cross-shaped structure 2210 from the top of the cross-shaped structure 2210; a lighting source base 2500 is arranged below the angle bracket 2200, and the other end of each of the two angle electric cylinders 2300 is hinged and fixed on the lighting source base 2500. Optionally, the other end of the angle electric cylinder 2300 can be fixed by a triangular protrusion formed on the lighting source base 2500. Triangular brackets 2400 are respectively formed on both sides of the lighting source base 2500, and the left and right sides of the middle of the angle bracket 2200 are respectively rotatably connected to the tops of the two triangular brackets 2400. Therefore, by pushing the "<" shaped structure 2220 by the angle electric cylinder 2300, the angle bracket 2200 can be rotated to obtain horizontal illumination and / or illumination at a certain angle with the horizontal plane. Optionally, the illumination at a certain angle with the horizontal plane is a 45-degree downward illumination.
[0073] See Figure 4 , on the lower left and right sides of the lighting source base 2500, a square protrusion and a strip protrusion are respectively arranged, and a slot is arranged at the middle position of the strip protrusion. The lifting bracket 2600 is a scissor-type lifting bracket 2600 (the scissor-type lifting bracket 2600 can adopt a conventional general structure, and its detailed structure will not be described here), and can achieve a lifting height of about 2m. Among them, the fork hinges on the left and right sides of the scissor-type lifting bracket 2600 are respectively connected to the lower left and right sides of the lighting source base 2500, and the upper ends of the fork hinges are respectively hinged to the square protrusion and slidably connected to the slot at the middle position of the strip protrusion to realize the stable lifting of the scissor-type lifting bracket 2600.
[0074] The bottom of the scissor-type lifting bracket 2600 also has a chassis, and the lower ends of the fork hinges are respectively hinged and fixed on the chassis; one end of the lifting electric cylinder 2700 is hinged on the middle hinge of the fork hinge of the scissor-type lifting bracket 2600, and the other end is also hinged and fixed on the chassis. Optionally, the other end of the angle electric cylinder 2300 can be hinged and fixed through a triangular protrusion formed on the chassis. Therefore, the vertical lifting of the scissor-type lifting bracket 2600 is achieved by pushing the middle hinge of the scissor-type lifting bracket 2600 through the lifting electric cylinder 2700, thereby controlling the height adjustment of the lifting bracket 2600.
[0075] From the above, it can be seen that the lifting electric cylinder 2700 is used to drive the scissor-type lifting bracket 2600 to lift the lighting source 2100, and the angle electric cylinder 2300 is used to drive the angle bracket 2200 to adjust the irradiation angle of the lighting source 2100, thereby realizing light irradiation at different heights and angles for the car driving simulator.
[0076] Optionally, a lighting scene such as dappled light may be realized by setting apertures, shading pattern sheets, etc. on the exit surfaces of each lamp of the lighting light source 2100, such as a high-power xenon lamp (or metal halide lamp) lamp array.
[0077] The electronic ballast 2810, servo control unit 2820, control host 2850 and power supply system 2860 are integrated in the chassis, and the chassis is divided into two front and rear accommodation spaces, one of which accommodates the electronic ballast 2810. Optionally, the electronic ballast 2810 is 4 groups; the other accommodation space, see Figure 5 , accommodating a servo control unit 2820, a control host 2850 and a power supply system 2860, etc. Optionally, the servo control unit 2820 contains 4 groups, 2 of which control lifting and the remaining 2 groups control angles; optionally, there are 2 control hosts 2850, which can be controlled by PLC; optionally, it can also include a relay 2840 for realizing high-power conversion and a control board 2830 for realizing signal conversion.
[0078] The electronic ballast 2810, servo control unit 2820, control host 2850 and power supply system 2860 are integrated into the chassis, making the movement of the whole machine simpler and more convenient. Different from the traditional control cabinet that is placed outside the bracket structure as a separate control cabinet, this integrated design only requires a 220V power supply cable for the external cable, which can make the overall lighting source 2100360° rotation around the car driving simulator a reality.
[0079] See also Figure 6The lifting bracket 2600 is arranged on the rail car 2910, and the rail car 2910 is arranged on a circular track 2920 or an arc track. The rail car 2910 is driven by an electric motor 2930 to move, and a non-slip rubber wheel 2940 is arranged at the bottom thereof to travel along the laid circular track 2920 or the arc track. The movement speed of the rail car 2910 can be controlled by remote control or software, so that the light source surrounds the car driving simulator 360. The position can be adjusted arbitrarily.
[0080] Optionally, a device capable of collecting outdoor ambient light intensity in real time may be included, and the solar simulator 2000 device may adjust the lighting source 2100 according to the collected outdoor light intensity information so as to keep it consistent with the outdoor light intensity.
[0081] It should be understood that the term “comprising” when used herein refers to the presence of a feature, an integer, or a component, but does not exclude the presence or addition of one or more other features, integers, or components.
[0082] It should be understood that the features described and / or illustrated may be combined with other features in the same or similar manner, or replace other features, without departing from the spirit of the present disclosure.
