Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle detection, in particular to a vehicle detection system. BACKGROUND

[0002] Vehicle detection is usually required after a certain period of use. Existing vehicle detection sites are generally provided with single-axis dynamometers. The existing vehicle detection device can only detect oil vehicles or new energy vehicles separately, and cannot detect oil vehicles and new energy vehicles compatibly, resulting in low detection efficiency of the vehicle detection device. SUMMARY

[0003] In view of the above problems, the present application provides a vehicle detection system, which can solve the problem that the existing vehicle detection device can only detect oil vehicles or new energy vehicles separately, and cannot detect oil vehicles and new energy vehicles compatibly, resulting in low detection efficiency of the vehicle detection device.

[0004] To solve the above technical problems, one technical scheme adopted by the present application is to provide a vehicle detection system, comprising: a plurality of vehicle detection devices arranged at intervals, the vehicle detection device comprising: a dynamometer; a diagnostic instrument of a new energy vehicle, in communication connection with the dynamometer; an exhaust analyzer of an oil vehicle, in communication connection with the dynamometer; a control device comprising: an identifier for identifying information of a vehicle to be detected; a distributor for distributing the vehicle to be detected to a preset vehicle detection device in front of the vehicle detection device for detection according to the information of the vehicle to be detected and information of a vehicle currently detected by each vehicle detection device and a vehicle queuing for detection; and a controller for sending a detection instruction to the vehicle detection device according to the information of the vehicle currently detected.

[0005] The identifier identifies the information of the vehicle to be detected, and the controller sends a detection instruction to the vehicle detection device according to the information of the vehicle currently detected, which can change the axle distance of the dynamometer, the communication connection between the diagnostic instrument of the new energy vehicle and the dynamometer, or the communication connection between the exhaust analyzer of the oil vehicle and the dynamometer, and further enable the vehicle detection system to detect oil vehicles and new energy vehicles compatibly. In addition, the distributor distributes the vehicle to be detected to the preset vehicle detection device in front of the vehicle detection device for detection according to the information of the vehicle to be detected and the information of the vehicle currently detected by each vehicle detection device and the vehicle queuing for detection, which can effectively utilize the vehicle detection device and improve the detection efficiency.

[0006] In some embodiments, the distributor is configured to distribute the vehicle to be detected to the preset vehicle detection device in front of the vehicle detection device for detection according to the power type of the vehicle to be detected and the power type of the vehicle currently detected by each vehicle detection device and the vehicle queuing for detection, so that the diagnostic instrument of the new energy vehicle and the exhaust analyzer of the oil vehicle of each vehicle detection device alternately perform three-electricity testing and exhaust detection; wherein the power type includes a pure oil vehicle, a pure electric vehicle and an oil-electric hybrid vehicle.

[0007] Since the diffusion of the exhaust gas discharged by the engine needs a certain time, and the gas sensor of the exhaust gas analyzer needs a certain time to fully separate the adsorbed exhaust gas, the exhaust gas detected by the exhaust gas analyzer and the three-electricity test of the diagnostic instrument are alternately performed, which is beneficial to waiting for the exhaust gas of the last detection to fully diffuse into the atmosphere or fully separate during the three-electricity test process, so as to reduce the influence on the subsequent detection and improve the detection accuracy of the subsequent exhaust gas analyzer.

[0008] In some embodiments, the distributor is used to distribute vehicles of different power types to the preset vehicle detection device for detection, so that among the vehicles queuing in front of each vehicle detection device for detection, the two adjacent vehicles are not all pure oil vehicles, and at least one of the three adjacent vehicles is a pure electric vehicle.

[0009] Since the two adjacent vehicles are not all pure oil vehicles, and at least one of the three adjacent vehicles is a pure electric vehicle, the exhaust gas analyzer of the oil vehicle does not need to work continuously; the exhaust gas detected by the exhaust gas analyzer and the three-electricity test of the diagnostic instrument are alternately performed, which is beneficial to waiting for the exhaust gas of the last detection to fully diffuse into the atmosphere or fully separate during the three-electricity test process, so as to reduce the influence on the subsequent detection and improve the detection accuracy of the subsequent exhaust gas analyzer.

[0010] In some embodiments, in response to the current vehicle being detected being a pure oil vehicle and the next vehicle being detected being a hybrid electric vehicle, the controller is configured to control the vehicle detection device to first detect the hybrid electric vehicle in the electric drive mode, and then detect the hybrid electric vehicle in the fuel drive mode or the fuel power generation mode; in response to the current vehicle being detected being a hybrid electric vehicle and the next vehicle being detected being a pure oil vehicle, the controller is configured to control the vehicle detection device to first detect the hybrid electric vehicle in the fuel drive mode or the fuel power generation mode, and then detect the hybrid electric vehicle in the electric drive mode.

[0011] When a pure oil vehicle and a hybrid electric vehicle are queued for detection, by selecting the detection mode of the hybrid electric vehicle, the exhaust gas analyzer of the oil vehicle does not need to work continuously. The exhaust gas detected by the exhaust gas analyzer and the three-electricity test of the diagnostic instrument are alternately performed, which is beneficial to waiting for the exhaust gas of the last detection to fully diffuse into the atmosphere or fully separate during the three-electricity test process, so as to reduce the influence on the subsequent detection and improve the detection accuracy of the subsequent exhaust gas analyzer.

[0012] In some embodiments, the dynamometer comprises a fixed dynamometer and a mobile dynamometer, and the distance between the mobile dynamometer and the fixed dynamometer is adjustable; the information of the vehicle to be detected comprises wheelbase information; the controller is further configured to adjust the distance between the mobile dynamometer and the fixed dynamometer according to the wheelbase information of the vehicle to be detected; and the distributor is configured to distribute the vehicle to be detected to a preset vehicle detection device for detection according to the wheelbase of the vehicle to be detected and the wheelbase of the vehicles currently detected by each vehicle detection device and the vehicles queued for detection, so that the wheelbase difference between two adjacent vehicles in the vehicles queued for detection in front of each vehicle detection device is less than a preset value.

[0013] By making the wheelbase difference between two adjacent vehicles less than a preset value, the time for waiting for the adjustment of the distance between the mobile dynamometer and the fixed dynamometer during the detection exchange of the two adjacent vehicles can be reduced, the detection efficiency can be improved, the moving range of the mobile dynamometer can be reduced, the wear and energy consumption can be reduced, and the service life of the mobile dynamometer can be prolonged.

[0014] In some embodiments, in response to the number of vehicles queued for detection in front of any vehicle detection device being greater than a threshold value, the distributor is configured to distribute a new vehicle to be detected to another vehicle detection device for detection, even if the wheelbase difference between the new vehicle to be detected and the last vehicle queued for detection in front of the other vehicle detection device is greater than a preset value.

[0015] Directing the new vehicle to be detected to the tail of the queue of the vehicle detection device with fewer queued vehicles can shorten the detection time and improve the detection efficiency.

[0016] In some embodiments, the dynamometer comprises a fixed dynamometer and a mobile dynamometer, and the distance between the mobile dynamometer and the fixed dynamometer is adjustable; the information of the vehicle to be detected comprises wheelbase information; the controller is further configured to adjust the distance between the mobile dynamometer and the fixed dynamometer according to the wheelbase information of the vehicle to be detected; and the distributor is configured to obtain the detection duration of a historical vehicle, confirm the pre-detection duration of the queued vehicle according to the detection duration of the historical vehicle, estimate the waiting duration of each queued vehicle according to the wheelbase difference between two adjacent queued vehicles and the speed of the adjustment of the distance between the mobile dynamometer and the fixed dynamometer, estimate the waiting duration of the newly added vehicle according to the information of the vehicles queued in front of each vehicle detection device, and direct the newly added vehicle to the tail of the queue with the shortest waiting duration.

[0017] By using the pre-detection duration of the queued vehicle and the moving waiting duration of the mobile dynamometer between two adjacent queued vehicles, the newly added vehicle can be directed to the tail of the queue with the shortest waiting duration, and the detection efficiency of the entire system can be improved.

[0018] In some embodiments, the controller is further configured to acquire driving data of the battery electric vehicle within a preset time period, and evaluate a detection pass probability of the battery electric vehicle according to the driving data; and the distributor is further configured to distribute the battery electric vehicle to the preset vehicle detection device for detection according to the detection pass probability of the battery electric vehicle.

[0019] Distributing the battery electric vehicle to the preset vehicle detection device for detection according to the detection pass probability of the battery electric vehicle can further optimize the detection efficiency.

[0020] In some embodiments, the distributor is further configured to distribute the battery electric vehicles with the same detection pass probability level to the vehicle detection devices for detection evenly.

[0021] Distributing the battery electric vehicles with the same detection pass probability level to the vehicle detection devices for detection evenly can optimize the waiting time of the vehicles queuing in front of the vehicle detection devices, and provide a better experience for the users.

[0022] In some embodiments, the vehicle detection device further comprises an image collector configured to collect license plate information of a vehicle currently being detected; and the controller is configured to send a detection instruction to the corresponding vehicle detection device if the license plate information of the vehicle currently being detected is consistent with the license plate information of the vehicle to be detected distributed by the distributor.

[0023] The controller confirms whether the license plate information of the vehicle currently being detected is consistent with the license plate information of the vehicle to be detected distributed by the distributor before sending a detection instruction to the corresponding vehicle detection device each time, which can reduce the risk caused by the mismatch between the detection instruction and the vehicle type.

[0024] In some embodiments, the dynamometer comprises: a fixed dynamometer comprising a first roller assembly and a first motor; and a mobile dynamometer comprising a second roller assembly and a second motor; wherein the first motor and the second motor are synchronous motors; the fixed dynamometer is a fixed dynamometer already existing in the vehicle detection site; the vehicle detection device further comprises an axle distance adjusting mechanism arranged between the fixed dynamometer and the mobile dynamometer and configured to adjust the distance between the mobile dynamometer and the fixed dynamometer; wherein the information of the vehicle to be detected comprises axle distance information; and the controller is further configured to control the axle distance adjusting mechanism to work according to the axle distance information of the vehicle to be detected, so as to adjust the distance between the mobile dynamometer and the fixed dynamometer.

[0025] The controller controls the wheelbase adjusting mechanism to adjust the distance between the mobile dynamometer and the fixed dynamometer according to the wheelbase information of the detected vehicle, and can be compatible with different types of oil vehicles and new energy vehicle detection, etc. Moreover, since the first motor of the fixed dynamometer and the second motor of the mobile dynamometer are two independent motors, there is no connection relationship between the mobile dynamometer and the fixed dynamometer, so that the existing single-axle fixed dynamometer can be upgraded to a double-axle dynamometer by only installing the upgrading equipment near the existing fixed dynamometer in the vehicle detection site.

[0026] In some embodiments, the vehicle detection device further comprises a bearing table, the wheelbase adjusting mechanism and the mobile dynamometer are arranged on the bearing table, and the mobile fork teeth are arranged on the side of the wheelbase adjusting mechanism away from the bearing table.

[0027] The bearing table can be used as a basic support platform of the overall structure. The bearing table provides mounting positions for the wheelbase adjusting mechanism and the mobile dynamometer. By limiting the mobile fork teeth to a position above the wheelbase adjusting mechanism, the mobile fork teeth can play a certain bearing role and improve the overall strength of the vehicle detection device.

[0028] The above description is only a summary of the technical solutions of the present application. In order to more clearly understand the technical means of the present application, the specific embodiments of the present application can be implemented according to the content of the specification, and in order to make the above and other purposes, features and advantages of the present application more obvious and easy to understand, the following specific embodiments of the present application are described.

[0029] The vehicle detection system of the present application comprises a vehicle detection device and a control device. The vehicle detection device comprises a dynamometer, a diagnostic instrument for new energy vehicles, and an exhaust analyzer for oil vehicles. The diagnostic instrument for new energy vehicles is in communication connection with the dynamometer, and the exhaust analyzer for oil vehicles is in communication connection with the dynamometer. The control device comprises an identifier and a controller. The identifier is used to identify the information of the detected vehicle, and the controller is used to send detection instructions to the vehicle detection device according to the information of the currently detected vehicle.

[0030] In the above manner, the vehicle detection system of the present application can make the diagnostic instrument and the dynamometer in communication connection, or the exhaust analyzer and the dynamometer in communication connection, etc., so that the vehicle detection system can be compatible with oil vehicles and new energy vehicle detection, etc., thereby improving the detection efficiency.

[0031] Further, the vehicle detection system comprises a plurality of vehicle detection devices arranged at intervals and a distributor. The distributor is used to distribute the detected vehicle to a predetermined vehicle detection device for detection according to the information of the detected vehicle and the information of the vehicle currently detected by each vehicle detection device and the vehicle waiting for detection.

[0032] By the above manner, the multiple vehicle detection devices can be effectively utilized, for example, by alternately distributing the new energy vehicles and the oil vehicles to the preset vehicle detection devices for detection, the diagnostic instrument of the new energy vehicle and the exhaust analyzer of the oil vehicle of the vehicle detection device can be alternately worked, which is beneficial to waiting for the exhaust of the last detection to be fully diffused to the atmosphere or to be fully separated from the gas sensor in the three-electricity test process, can reduce the influence on the subsequent detection, and improve the detection precision of the subsequent exhaust analyzer; by distributing the vehicles with close wheelbase to the preset vehicle detection devices for detection, the waiting time of the vehicles queuing for detection can be reduced, and the detection efficiency is further improved.

For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0050] The vehicle usually needs to be detected after a certain period of use. The existing vehicle detection site is generally provided with a single-axis dynamometer. The existing vehicle detection device can only detect oil cars or new energy cars, and cannot detect oil cars and new energy cars (such as pure electric cars).

[0051] The prior art also provides a vehicle detection device for an oil-electric hybrid vehicle for vehicle detection of an oil-electric hybrid vehicle. However, the vehicle detection device for an oil-electric hybrid vehicle at the existing vehicle detection site is specifically used for detecting oil-electric hybrid vehicles, and has a low utilization rate in the current situation where the number of oil-electric hybrid vehicles is small.

[0052] In order to solve the problem that the existing vehicle detection device can only detect oil cars or new energy cars, and cannot detect oil cars and new energy cars, the present application proposes a method of simultaneously arranging an oil car exhaust analyzer and a new energy car diagnostic instrument on the vehicle detection device, so that the same vehicle detection device can detect oil cars and new energy cars. Alternatively, the existing vehicle detection device for an oil-electric hybrid vehicle is upgraded in software to enable it to detect oil cars or new energy cars.

[0053] However, the applicant finds that in the current situation where new energy vehicles are increasingly occupying the market, when a vehicle detection site is equipped with multiple vehicle detection devices as described above, how to guide vehicles for detection and more effectively utilize vehicle detection devices becomes a problem to be solved.

[0054] The present application provides a vehicle detection system, comprising: multiple vehicle detection devices arranged at intervals, wherein each vehicle detection device comprises: a dynamometer; a diagnostic instrument for new energy vehicles, which is in communication connection with the dynamometer; and an exhaust analyzer for oil vehicles, which is in communication connection with the dynamometer. The control device comprises: an identifier for identifying information of a vehicle to be detected; a distributor for distributing the vehicle to be detected to a preset vehicle detection device for detection according to the information of the vehicle to be detected and information of a vehicle currently being detected and a vehicle queuing for detection by each vehicle detection device; and a controller for sending a detection instruction to the vehicle detection device according to the information of the vehicle currently being detected.

[0055] The present application identifies the information of the vehicle to be detected by the identifier, and the controller sends a detection instruction to the vehicle detection device according to the information of the vehicle currently being detected, so as to change the wheelbase of the dynamometer, the communication connection between the diagnostic instrument and the dynamometer, or the communication connection between the exhaust analyzer and the dynamometer, etc., thereby being compatible with the detection of oil vehicles and new energy vehicles, etc. In addition, the distributor distributes the vehicle to be detected to a preset vehicle detection device for detection according to the information of the vehicle to be detected and information of a vehicle currently being detected and a vehicle queuing for detection by each vehicle detection device, thereby effectively utilizing the vehicle detection device and improving the detection efficiency.

[0056] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 1 is a structural diagram of a vehicle detection system according to one or more embodiments; Figure 2 is a top view of a vehicle detection device according to one or more embodiments; Figure 3 is a side view of a vehicle detection device according to one or more embodiments; Figure 4is a structural diagram of a vehicle detection device according to one or more embodiments. The present application provides a vehicle detection system. The vehicle detection system 1000 comprises a plurality of vehicle detection devices 100 arranged at intervals and a control device 200. The vehicle detection device 100 comprises a dynamometer 10, a new energy vehicle diagnostic instrument 14 and an oil vehicle tail gas analyzer 15. The new energy vehicle diagnostic instrument 14 is in communication connection with the dynamometer 10. The oil vehicle tail gas analyzer 15 is in communication connection with the dynamometer 10. The control device 200 comprises an identifier 201, an allocator 203 and a controller 202. The identifier 201 is used to identify the information of the vehicle to be detected. The allocator 203 is used to allocate the vehicle to be detected to the preset vehicle detection device 100 in front of the vehicle detection device 100 for detection according to the information of the vehicle to be detected and the information of the vehicle currently detected by each vehicle detection device 100 and the vehicle queuing for detection. The controller 202 is used to send a detection instruction to the vehicle detection device 100 according to the information of the vehicle currently detected.

[0057] Among them, a plurality of vehicle detection devices 100 can be arranged in a row in a vehicle detection place. The specific embodiment of the present application takes three vehicle detection devices 100 arranged in a row as an example for illustration. The identifier 201 and the allocator 203 of the control device 200 can be arranged at the entrance of the vehicle detection place. After the identifier 201 identifies the information of the incoming vehicle to be detected, the allocator 203 prompts the vehicle owner to drive the vehicle to be detected to the preset vehicle detection device 100 in front of the vehicle detection device 100 for queuing for detection. The controller 202 is in communication connection with the identifier 201, the allocator 203 and each vehicle detection device 100 respectively. The setting position of the controller 202 is not limited.

[0058] Among them, the dynamometer 10 can detect all driving forms of vehicles. Among them, the vehicles can be but not limited to front-wheel drive, rear-wheel drive and four-wheel drive, etc.

[0059] The new energy vehicle diagnostic instrument 14 can perform three-electricity test on the new energy vehicle. The three-electricity test includes battery, motor and electric control test, etc. The diagnostic instrument 14 is a conventional component in the field, which is not limited here. The new energy vehicle diagnostic instrument 14 is in communication connection with the dynamometer 10, which can detect the new energy vehicle. Among them, the dynamometer 10 comprises a signal interface. The signal interface is configured to be able to connect the diagnostic instrument 14. The diagnostic instrument 14 is in communication connection with the dynamometer 10 through a signal interface.

[0060] The tail gas analyzer 15 of the oil vehicle can detect the exhaust of the oil vehicle. The tail gas analyzer 15 is a conventional component in the field and is not limited herein. The tail gas analyzer 15 of the oil vehicle is in communication connection with the dynamometer 10 and can detect the oil vehicle. The dynamometer 10 includes another signal interface. The other signal interface is configured to be able to connect the tail gas analyzer 15. The tail gas analyzer 15 is in communication connection with the dynamometer 10 through the other signal interface. The signal interface and the other signal interface can be the same signal interface or different signal interfaces, which are not limited herein.

[0061] The identifier 201 includes but is not limited to an image collector, a scanner, and the like. The detected vehicle can be but is not limited to an oil vehicle and a new energy vehicle. The information of the detected vehicle includes but is not limited to a motor vehicle driving license, a motor vehicle registration certificate, license plate information, a VIN (Vehicle Identification Number) code, and the like.

[0062] The controller 202 in the control device 200 can send different detection instructions to the vehicle detection device 100 according to the different information of the detected vehicle identified by the identifier 201.

[0063] For example, when the information of the detected vehicle is an oil vehicle and the wheelbase is 2500 mm, the controller 202 sends a detection instruction to the vehicle detection device 100, which controls the dynamometer 10 to adjust the wheelbase to 2500 mm and makes the tail gas analyzer 15 in communication connection with the dynamometer 10. At this time, the worker connects the tail gas analyzer 15 to the detected vehicle.

[0064] When the information of the detected vehicle is a new energy vehicle and the wheelbase is 2800 mm, the controller 202 sends a detection instruction to the vehicle detection device 100, which controls the dynamometer 10 to adjust the wheelbase to 2800 mm and makes the diagnostic instrument 14 in communication connection with the dynamometer 10. At this time, the worker connects the diagnostic instrument 14 to the detected vehicle. Of course, the information of the detected vehicle can also be other wheelbase values, which are not described one by one herein.

[0065] By identifying the information of the detected vehicle through the identifier 201, the controller 202 sends a detection instruction to the vehicle detection device 100 according to the current information of the detected vehicle, which can change the wheelbase of the dynamometer 10, the communication connection between the diagnostic instrument 14 and the dynamometer 10, or the communication connection between the tail gas analyzer 15 and the dynamometer 10, and the like, so as to make the vehicle detection system compatible with oil vehicle detection and new energy vehicle detection.

[0066] The distributor 203 can include a circuit capable of operation and a prompting device. For example, the distributor 203 can include a calculator (such as a single-chip microcomputer or the like) and a display screen. The calculator is used to calculate to which vehicle detection device 100 the detected vehicle should be distributed in front of for detection according to the information of the detected vehicle and the information of the vehicle currently detected by each vehicle detection device 100 and the vehicle queuing for detection. The prompting device can also include a voice prompting device or a display device with a voice function, for prompting the vehicle owner to drive the detected vehicle to the preset vehicle detection device 100 in front of for queuing for detection. The distributor 203 distributes the detected vehicle to the preset vehicle detection device 100 in front of for detection according to the information of the detected vehicle and the information of the vehicle currently detected by each vehicle detection device 100 and the vehicle queuing for detection, which can effectively utilize the vehicle detection device 100 and improve the detection efficiency.

[0067] The vehicle detection system 1000 of the present application can enable the diagnostic instrument 14 to be communicatively connected with the dynamometer 10, or the exhaust analyzer 15 to be communicatively connected with the dynamometer 10, and the like, so that the vehicle detection system 1000 can be compatible with oil vehicle and new energy vehicle detection, thereby improving the detection efficiency. Further, the present application can effectively utilize multiple vehicle detection devices 100, for example, by alternately distributing new energy vehicles and oil vehicles to the preset vehicle detection device 100 in front of for detection, the diagnostic instrument 14 of the new energy vehicle and the exhaust analyzer 15 of the oil vehicle of the vehicle detection device 100 can be alternately operated, which is beneficial to waiting for the exhaust of the last detection to be fully diffused into the atmosphere or fully separated from the gas sensor during the three-electricity test process, so as to reduce the influence on the subsequent detection and improve the detection accuracy of the subsequent exhaust analyzer 15; by distributing vehicles with similar wheelbase to the preset vehicle detection device 100 in front of for detection, the waiting time of the vehicle queuing for detection can be reduced, thereby improving the detection efficiency.

[0068] In some embodiments, the distributor 203 is used to distribute the detected vehicle to the preset vehicle detection device 100 in front of for detection according to the power type of the detected vehicle and the power type of the vehicle currently detected by each vehicle detection device 100 and the vehicle queuing for detection, so that the diagnostic instrument 14 of the new energy vehicle and the exhaust analyzer 15 of the oil vehicle of each vehicle detection device 100 alternately perform three-electricity test and exhaust detection; wherein the power type includes pure oil vehicle, pure electric vehicle and oil-electric hybrid vehicle.

[0069] The pure oil vehicle can be a diesel vehicle or a gasoline vehicle. The diagnostic instrument 14 of the new energy vehicle and the exhaust analyzer 15 of the oil vehicle alternately perform three-electricity testing and exhaust detection. It can be understood that at least one three-electricity test of the diagnostic instrument 14 of the new energy vehicle is performed between exhaust detections of the exhaust analyzer 15 of the oil vehicle in adjacent two times, so that the exhaust analyzer 15 of the oil vehicle does not work continuously. In the case that the number of new energy vehicles is sufficient, at least multiple three-electricity tests of the diagnostic instrument 14 of the new energy vehicle can be performed between exhaust detections of the exhaust analyzer 15 of the oil vehicle in adjacent two times, so that the working interval of the exhaust analyzer 15 of the oil vehicle is longer.

[0070] It can be understood that, since the diffusion of the exhaust gas discharged by the engine needs a certain time, and the exhaust gas adsorbed by the gas sensor of the exhaust analyzer 15 needs a certain time to be fully detached, the exhaust detection by the exhaust analyzer 15 and the three-electricity test by the diagnostic instrument 14 are alternately performed, which is beneficial to waiting for the exhaust of the last detection to fully diffuse into the atmosphere or fully detach during the three-electricity test, so as to reduce the influence on the subsequent detection and improve the detection accuracy of the subsequent exhaust analyzer 15.

[0071] In some embodiments, the distributor 203 is configured to distribute vehicles of different power types to the preset vehicle detection device 100 for detection, so that in the vehicles waiting in line for detection in front of each vehicle detection device 100, the two adjacent vehicles are not all pure oil vehicles, and at least one of the three adjacent vehicles is a pure electric vehicle.

[0072] The two adjacent vehicles not being all pure oil vehicles can be understood as one pure oil vehicle and one pure electric vehicle, one pure oil vehicle and one hybrid vehicle, or one pure electric vehicle and one hybrid vehicle. At least one of the three adjacent vehicles being a pure electric vehicle can be understood as one pure oil vehicle and one pure electric vehicle and another pure oil vehicle, one pure oil vehicle and one hybrid vehicle and one pure electric vehicle, or one pure electric vehicle and one hybrid vehicle and another pure electric vehicle.

[0073] It can be understood that, since the two adjacent vehicles are not all pure oil vehicles, and at least one of the three adjacent vehicles is a pure electric vehicle, the exhaust analyzer 15 of the oil vehicle does not need to work continuously. The exhaust detection by the exhaust analyzer 15 and the three-electricity test by the diagnostic instrument 14 are alternately performed, which is beneficial to waiting for the exhaust of the last detection to fully diffuse into the atmosphere or fully detach during the three-electricity test, so as to reduce the influence on the subsequent detection and improve the detection accuracy of the subsequent exhaust analyzer 15.

[0074] In some embodiments, in response to the current detected vehicle being a pure oil vehicle and the next detected vehicle being a hybrid vehicle, the controller 202 is configured to control the vehicle detection device 100 to first detect the hybrid vehicle in the electric drive mode, and then detect the hybrid vehicle in the fuel drive mode or the fuel power generation mode; in response to the current detected vehicle being a hybrid vehicle and the next detected vehicle being a pure oil vehicle, the controller 202 is configured to control the vehicle detection device 100 to first detect the hybrid vehicle in the fuel drive mode or the fuel power generation mode, and then detect the hybrid vehicle in the electric drive mode.

[0075] The fuel drive mode can be understood as driving by using the engine, and the fuel power generation mode can be understood as generating power by using the engine to charge the battery of the vehicle.

[0076] When a pure oil vehicle and a hybrid vehicle are detected in succession, by selecting the detection mode of the hybrid vehicle, the tail gas analyzer 15 of the pure oil vehicle does not need to work continuously. By alternately detecting tail gas by the tail gas analyzer 15 and diagnosing by the diagnostic instrument 14, the three-electricity test is beneficial to waiting for the tail gas of the last detection to diffuse to the atmosphere or to separate sufficiently during the three-electricity test, which can reduce the influence on the subsequent detection and improve the detection accuracy of the subsequent tail gas analyzer 15.

[0077] In some embodiments, the dynamometer 10 includes a fixed dynamometer 20 and a movable dynamometer 12, and the distance between the movable dynamometer 12 and the fixed dynamometer 20 is adjustable; the information of the detected vehicle includes the wheelbase information; the controller 202 is further configured to adjust the distance between the movable dynamometer 12 and the fixed dynamometer 20 according to the wheelbase information of the detected vehicle; and the distributor 203 is configured to distribute the detected vehicle to a preset vehicle detection device 100 for detection according to the wheelbase of the detected vehicle and the wheelbase of the vehicle currently detected by each vehicle detection device 100 and the vehicle waiting for detection in line, so that the wheelbase difference between two adjacent vehicles in line waiting for detection in front of each vehicle detection device 100 is less than a preset value.

[0078] The wheelbase adjustment mechanism 13 can be an electric motor, a pneumatic cylinder, etc., which will be described later. The preset value can be 100-500 mm, such as 200 mm, 300 mm, or 400 mm. It can be understood that the larger the preset value, the larger the wheelbase difference between two adjacent vehicles, and the longer the time required for adjusting the distance between the fixed dynamometer 20 and the movable dynamometer 12 from the current detected vehicle to the next detected vehicle, and the lower the detection efficiency. If the preset value is too small, it may cause the wheelbase difference between the newly arrived vehicle to be detected and all the vehicles in line at the tail to be greater than the preset value, resulting in frequent system alarms.

[0079] By the wheelbase difference between the two adjacent vehicles being less than the preset value, the time for waiting for the distance adjustment between the fixed dynamometer 20 and the mobile dynamometer 12 during the detection exchange of the two adjacent vehicles can be reduced, the detection efficiency is improved, the moving range of the mobile dynamometer 12 is reduced, the wear and energy consumption are reduced, and the service life of the mobile dynamometer 12 is prolonged.

[0080] In some embodiments, in response to the number of vehicles queuing in front of any vehicle detection device 100 for detection being greater than a threshold value, the distributor is configured to allocate a new vehicle for detection to the queue in front of the other vehicle detection device 100 for detection, even if the wheelbase difference between the new vehicle for detection and the last vehicle in the queue in front of the other vehicle detection device 100 for detection is greater than the preset value.

[0081] The threshold value can be 5-10 vehicles. The number of vehicles queuing for detection being greater than the threshold value can be understood as the number of vehicles queuing for detection being greater than 5, greater than 7, or greater than 10.

[0082] Specifically, when the number of vehicles queuing in front of a certain vehicle detection device 100 for detection is large, although the wheelbase difference between the two adjacent vehicles is less than the preset value, the time for waiting for the distance adjustment between the fixed dynamometer 20 and the mobile dynamometer 12 during the detection exchange of the two adjacent vehicles can be reduced, but the detection efficiency is low due to the overall queuing time process. Directing the new vehicle for detection to the tail of the queue of the vehicle detection device 100 with a smaller number of vehicles queuing for detection can shorten the detection time as a whole and improve the detection efficiency.

[0083] In some embodiments, the dynamometer 10 includes a fixed dynamometer 20 and a mobile dynamometer 12, the distance between the mobile dynamometer 12 and the fixed dynamometer 20 is adjustable; the information of the vehicle for detection includes wheelbase information; the controller 202 is further configured to adjust the distance between the mobile dynamometer 12 and the fixed dynamometer 20 according to the wheelbase information of the vehicle for detection; the distributor 203 is further configured to obtain the detection duration of the historical vehicle, confirm the pre-detection duration of the vehicle queuing for detection according to the detection duration of the historical vehicle, estimate the waiting duration of each vehicle queuing for detection by the wheelbase difference between the two adjacent vehicles queuing for detection and the speed of adjusting the distance between the fixed dynamometer 20 and the mobile dynamometer 12, estimate the waiting duration of the new vehicle for detection according to the information of the vehicle queuing in front of each vehicle detection device 100, and direct the new vehicle to the tail of the queue with the shortest waiting duration.

[0084] According to the detection time length of the historical vehicle, the pre-detection time length of the queuing vehicle can be understood as the pre-detection time length of the queuing vehicle according to the historical detection time length of the same type of vehicle as the queuing vehicle for detection. Alternatively, for a vehicle that is not detected for the first time, the historical detection time length of the queuing vehicle is used as the pre-detection time length of the queuing vehicle, thereby improving the prediction accuracy. Alternatively, for a vehicle that is detected for the first time, the historical detection time length of a vehicle of the same type and close to the service life is used as the pre-detection time length of the queuing vehicle, thereby improving the prediction accuracy. Alternatively, for a vehicle that is detected for the first time, the historical detection time length of a vehicle of the same type and close to the driving mileage is used as the pre-detection time length of the queuing vehicle, thereby improving the prediction accuracy.

[0085] By using the pre-detection time length of the queuing vehicle and the moving waiting time length of the two adjacent queuing vehicles for moving to the dynamometer, the new vehicle is guided to the tail of the queue with the shortest waiting time length, and the detection efficiency of the entire system can be improved.

[0086] In some embodiments, the controller 202 is further configured to obtain driving data of the pure electric vehicle within a preset time period, and evaluate the detection pass probability of the pure electric vehicle according to the driving data; and the distributor 203 is further configured to distribute the pure electric vehicle to the preset vehicle detection device 100 for detection according to the detection pass probability of the pure electric vehicle.

[0087] In some embodiments, the controller 202 is further configured to obtain driving data of the pure electric vehicle within a preset time period, and evaluate the detection pass probability of the pure electric vehicle according to the driving data; and the distributor 203 is further configured to distribute the pure electric vehicle to the preset vehicle detection device 100 for detection according to the detection pass probability of the pure electric vehicle.

[0088] In some embodiments, the controller 202 is further configured to obtain driving data of the pure electric vehicle within a preset time period, and evaluate the detection pass probability of the pure electric vehicle according to the driving data; and the distributor 203 is further configured to distribute the pure electric vehicle to the preset vehicle detection device 100 for detection according to the detection pass probability of the pure electric vehicle.

[0089] In some embodiments, the distributor 203 is further configured to distribute the pure electric vehicles with the same detection pass probability level to the plurality of vehicle detection devices 100 for detection.

[0090] The detection pass probability level can be divided into three levels: high, medium and low. The average number of pure electric vehicles in each level is evenly distributed to the vehicle detection device 100, which can optimize the waiting time of the vehicles waiting in front of the vehicle detection device 100, and provide a better experience for the user.

[0091] In some embodiments, the vehicle detection device 100 further comprises an image collector 16 for collecting the license plate information of the currently detected vehicle; the controller 202 is configured to send a detection instruction to the corresponding vehicle detection device 100 when the license plate information of the currently detected vehicle is consistent with the license plate information of the vehicle to be detected allocated by the allocator 203.

[0092] The image collector 16 can scan the driving license or license plate of different detected vehicles and obtain the information of the detected vehicle, such as vehicle type and vehicle wheelbase. The image collector 16 can be a camera. The allocator 203 guides the vehicle to queue in front of the corresponding vehicle detection device 100, and the vehicle detected by the vehicle detection device 100 should be determined. However, there may be users who temporarily drive away from the detection, or other vehicles who insert the queue, or some vehicles who fail to pass the detection once, and the staff requires to drive out of the vehicle detection device 100 and re-enter. Therefore, before sending a detection instruction to the corresponding vehicle detection device 100 each time, it is necessary to confirm whether the license plate information of the currently detected vehicle is consistent with the license plate information of the vehicle to be detected allocated by the allocator 203, so as to reduce the risk caused by the mismatch between the detection instruction and the vehicle type.

[0093] When the license plate information of the currently detected vehicle is inconsistent with the license plate information of the vehicle to be detected allocated by the allocator 203, an alarm or a request prompt can be sent to the staff to confirm whether to send a detection instruction according to the actual license plate information of the currently detected vehicle detected by the image collector 16.

[0094] In some embodiments, referring to Figure 2 , the dynamometer 10 comprises a fixed dynamometer 20 and a mobile dynamometer 12. The fixed dynamometer 20 comprises a first roller assembly 210 and a first motor (not shown in the figure); the mobile dynamometer 12 comprises a second roller assembly 121 and a second motor (not shown in the figure); the first motor and the second motor are synchronous motors; the fixed dynamometer 20 is a fixed dynamometer already existing in the vehicle detection site. The vehicle detection device 100 further comprises a wheelbase adjustment mechanism 13. The wheelbase adjustment mechanism 13 is arranged between the fixed dynamometer 20 and the mobile dynamometer 12, and is used to adjust the distance between the mobile dynamometer 12 and the fixed dynamometer 20. The information of the detected vehicle includes the wheelbase information. The controller 202 is further configured to control the wheelbase adjustment mechanism 13 to work according to the wheelbase information of the detected vehicle, so as to adjust the distance between the mobile dynamometer 12 and the fixed dynamometer 20.

[0095] The first motor and the second motor are synchronous motors, which can realize synchronous rolling of the first roller assembly 210 and the second roller assembly 121. Since the first motor of the fixed dynamometer 20 and the second motor of the mobile dynamometer 12 are two independent motors, there is no connection relationship between the mobile dynamometer 12 and the fixed dynamometer 20. Therefore, the existing single-axle fixed dynamometer 20 can be upgraded to a double-axle dynamometer by installing the upgrading device 10a near the existing fixed dynamometer 20 in the vehicle detection site. Here, the upgrading device 10a will be described in detail later. If a belt or a chain is used to realize synchronous rolling of the first roller assembly 210 and the second roller assembly 121, the existing fixed dynamometer 20 in the vehicle detection site needs to be modified and upgraded, for example, a driving wheel needs to be installed, which increases the difficulty of upgrading the existing single-axle fixed dynamometer 20 to a double-axle dynamometer. In addition, since the first motor of the fixed dynamometer 20 and the second motor of the mobile dynamometer 12 are two independent motors, the vehicle detection device 100 can also detect front-wheel drive or rear-wheel drive vehicles.

[0096] The fixed dynamometer 20 can detect front-wheel drive or rear-wheel drive vehicles. The mobile dynamometer 12 can detect rear-wheel drive or front-wheel drive vehicles. The positions of the fixed dynamometer 20 and the mobile dynamometer 12 are not limited. The structure of the fixed dynamometer 20 and the structure of the mobile dynamometer 12 can be the same. The fixed dynamometer 20 can be, but is not limited to, a single-axle dynamometer.

[0097] One end of the wheelbase adjustment mechanism 13 is detachably or fixedly connected with the fixed dynamometer 20. The other end of the wheelbase adjustment mechanism 13 is detachably or fixedly connected with the mobile dynamometer 12. The wheelbase adjustment mechanism 13 can adjust the distance between the mobile dynamometer 12 and the fixed dynamometer 20, thereby adjusting different wheelbases.

[0098] The fixed dynamometer 20 can be in a stationary state, and the mobile dynamometer 12 can be in a moving state. At this time, the wheelbase adjustment mechanism 13 drives the mobile dynamometer 12, so that the position of the mobile dynamometer 12 relative to the fixed dynamometer 20 changes, thereby adjusting the distance between the mobile dynamometer 12 and the fixed dynamometer 20. Alternatively, the fixed dynamometer 20 can be in a moving state, and the mobile dynamometer 12 can be in a stationary state. At this time, the wheelbase adjustment mechanism 13 drives the fixed dynamometer 20, so that the position of the fixed dynamometer 20 relative to the mobile dynamometer 12 changes, thereby adjusting the distance between the mobile dynamometer 12 and the fixed dynamometer 20. Alternatively, the fixed dynamometer 20 and the mobile dynamometer 12 are both in a moving state, and the wheelbase adjustment mechanism 13 simultaneously drives the mobile dynamometer 12 and the fixed dynamometer 20, so that the positions of the mobile dynamometer 12 and the fixed dynamometer 20 relatively change, thereby adjusting the distance between the mobile dynamometer 12 and the fixed dynamometer 20.

[0099] Different vehicles to be detected can have different wheelbases. The distance between the mobile dynamometer 12 and the fixed dynamometer 20 can be the wheelbase of the vehicle to be detected. The controller 202 can control the wheelbase adjustment mechanism 13 to adjust the distance between the mobile dynamometer 12 and the fixed dynamometer 20 according to the wheelbase information.

[0100] The controller 202 controls the wheelbase adjustment mechanism 13 to adjust the distance between the mobile dynamometer 12 and the fixed dynamometer 20 according to the wheelbase information of the vehicle to be detected, which can be compatible with different types of oil vehicles and new energy vehicle detection, etc.

[0101] When the controller 202 controls the wheelbase adjustment mechanism 13 to complete the work, the controller 202 can send a prompt instruction. The prompt instruction can prompt the driver to drive the vehicle to be detected into the vehicle detection device 100. Alternatively, the dynamometer 10 is provided with a safety barrier (not shown in the figure). When the controller 202 controls the wheelbase adjustment mechanism 13 to complete the work, the safety barrier is automatically opened, and at this time the driver can drive the vehicle to be detected into the vehicle detection device 100.

[0102] In some embodiments, the fixed dynamometer 20 in the vehicle detection device 100 is the existing fixed dynamometer 20 in the vehicle detection site.

[0103] The fixed dynamometer 20 in the vehicle detection device 100 can be the existing fixed dynamometer 20 in the vehicle detection site. The vehicle detection device 100 includes the upgrading equipment 10a. The upgrading equipment 10a includes the mobile dynamometer 12 and the wheelbase adjustment mechanism 13. Before the upgrading equipment 10a is installed in the vehicle detection site, the fixed dynamometer 20 already exists in the vehicle detection site, and only needs to be installed near the fixed dynamometer 20.

[0104] By reusing the fixed dynamometer 20 in the vehicle detection site, the cost can be reduced and the space occupation can be reduced, etc.

[0105] In other embodiments, the fixed dynamometer 20 can be rearranged together with the mobile dynamometer 12 and the wheelbase adjustment mechanism 13 in the vehicle detection site.

[0106] In some embodiments, the vehicle detection device 100 further includes a signal interface (not shown in the figure). The signal interface is configured to be able to connect the diagnostic instrument 14 of the new energy vehicle and the exhaust analyzer 15 of the oil vehicle. The controller 202 is further configured to send a prompt instruction according to the information of the vehicle to be detected, for prompting the staff to connect the diagnostic instrument 14 of the new energy vehicle and / or the exhaust analyzer 15 of the oil vehicle to the vehicle to be detected and the vehicle detection device 100, respectively.

[0107] The signal interface can be used as a medium for connecting the mobile dynamometer 12 and the diagnostic instrument 14 or the exhaust analyzer 15. The signal interface can be adapted to the diagnostic instrument 14 and the exhaust analyzer 15. The signal interface can be connected to the diagnostic instrument 14 of the new energy vehicle, or the signal interface can be connected to the exhaust analyzer 15 of the oil vehicle.

[0108] The controller 202 can send different prompt instructions to the staff according to the information of the detected vehicle. The prompt instruction can be, but is not limited to, a prompt information displayed on the display screen or a voice guidance information.

[0109] For example, when the detected vehicle is an oil vehicle, the prompt instruction prompts the staff to connect the exhaust analyzer 15 between the signal interface of the vehicle detection device 100 and the oil vehicle. When the detected vehicle is a new energy vehicle, the prompt instruction prompts the staff to connect the exhaust analyzer 15 between the signal interface of the vehicle detection device 100 and the new energy vehicle.

[0110] The signal interface can be connected to the diagnostic instrument 14 of the new energy vehicle and the exhaust analyzer 15 of the oil vehicle, so that the upgraded equipment 10a can be compatible with all driving forms of the detected vehicle. In addition, the controller 202 sends the prompt instruction to prompt the staff to connect the diagnostic instrument 14 and / or the exhaust analyzer 15 between the detected vehicle and the vehicle detection device 100, which can shorten the connection time and improve the detection efficiency.

[0111] The controller 202 can control the wheelbase adjusting mechanism 13 to work and send the prompt instruction to prompt the staff to connect the diagnostic instrument 14 of the new energy vehicle and / or the exhaust analyzer 15 of the oil vehicle between the detected vehicle and the vehicle detection device 100 according to the information of the detected vehicle, which can shorten the detection time and improve the detection efficiency.

[0112] In other embodiments, the controller 202 can first control the wheelbase adjusting mechanism 13 to work, and then send the prompt instruction to prompt the staff to connect the diagnostic instrument 14 of the new energy vehicle and / or the exhaust analyzer 15 of the oil vehicle between the detected vehicle and the vehicle detection device 100.

[0113] The number of the signal interfaces can be one, two, three or more. Specifically, the signal interface can be a plug-in signal interface (not shown in the figure). The diagnostic instrument 14 and the exhaust analyzer 15 can be connected to the mobile dynamometer 12 through the plug-in signal interface, which can shorten the replacement time of the diagnostic instrument 14 and the exhaust analyzer 15 and improve the detection efficiency of the detected vehicle.

[0114] In some embodiments, the signal interface is a single interface. Alternatively, the signal interface comprises a first signal interface (not shown in the figure) and a second signal interface (not shown in the figure). The first signal interface is configured to be connected to the diagnostic instrument 14 of the new energy vehicle. The second signal interface is configured to be connected to the exhaust analyzer 15 of the oil vehicle.

[0115] When the signal interface is one, the signal interface is a single interface. The single interface uses a standardized interface to achieve universal connection. When the detected vehicle is an oil vehicle, the single interface can be connected to the exhaust analyzer 15 for communication connection with the exhaust analyzer 15. When the detected vehicle is a new energy vehicle, the single interface can be connected to the diagnostic instrument 14 for communication connection with the diagnostic instrument 14.

[0116] Alternatively, when the signal interface is two, the signal interface comprises a first signal interface and a second signal interface. The first signal interface can be connected to the diagnostic instrument 14 of the new energy vehicle. The first signal interface is used for communication connection with the diagnostic instrument 14. The second signal interface can be connected to the exhaust analyzer 15 of the oil vehicle. The second signal interface is used for communication connection with the exhaust analyzer 15.

[0117] The single interface, the first signal interface, and the second signal interface described above can all be a reserved RS485 interface. The reserved RS485 interface can support RS485 protocol transmission of real-time detection data.

[0118] The single interface can reduce the complexity of the use of the upgrading device 10a, achieve compatibility of oil vehicles and new energy vehicles, etc. Alternatively, the first signal interface and the second signal interface can improve the stability of data transmission, achieve compatibility of oil vehicles and new energy vehicles, etc.

[0119] The single interface described above can be a plug-in first interface. The first signal interface can be a plug-in first signal interface. The second signal interface can be a plug-in second signal interface. During the detection of the detected vehicle by the upgrading device 10a, the corresponding exhaust analyzer 15 and diagnostic instrument 14, etc. can be selected according to the type of the detected vehicle.

[0120] In other embodiments, the signal interface can also be in communication connection with the bearing mechanism 11 or the wheelbase adjustment mechanism 13, which is not limited here. When the number of signal interfaces is multiple, different signal interfaces can be arranged in one of the bearing mechanism 11, the mobile dynamometer 12, and the wheelbase adjustment mechanism 13, two of them, and all of them, etc., which is not limited here.

[0121] The upgrading device 10a described above can also reserve an access to a 220V alternating current power supply, which can achieve power connection, etc.

[0122] In some embodiments, the diagnostic instrument 14 of the new energy vehicle and the exhaust analyzer 15 of the oil vehicle are both in communication connection with the dynamometer 10. The controller 202 is configured to: in response to the detected vehicle being a pure electric vehicle, control the diagnostic instrument 14 of the new energy vehicle and the dynamometer 10 to work together; in response to the detected vehicle being a pure oil vehicle, control the exhaust analyzer 15 of the oil vehicle and the dynamometer 10 to work together; and in response to the detected vehicle being a hybrid vehicle, control the diagnostic instrument 14 of the new energy vehicle and the dynamometer 10 to work together in a first time period, and control the exhaust analyzer 15 of the oil vehicle and the dynamometer 10 to work together in a second time period.

[0123] In some embodiments, the diagnostic instrument 14 and the exhaust analyzer 15 are both pre-connected to the dynamometer 10, so that the diagnostic instrument 14 and the exhaust analyzer 15 are both in communication connection with the dynamometer 10.

[0124] When the detected vehicle is a pure electric vehicle, the diagnostic instrument 14 and the dynamometer 10 work together, and at this time, the worker connects the diagnostic instrument 14 to the pure electric vehicle.

[0125] When the detected vehicle is a pure oil vehicle, the exhaust analyzer 15 and the dynamometer 10 work together, and at this time, the worker connects the exhaust analyzer 15 to the pure oil vehicle.

[0126] The hybrid vehicle can include, but is not limited to, an oil-electric dual-drive vehicle and a range-extender vehicle. The hybrid vehicle needs to be tested for three-electricity and exhaust, etc. When the detected vehicle is a hybrid vehicle, in a first time period, the diagnostic instrument 14 of the new energy vehicle and the dynamometer 10 work together, and at this time, the worker connects the diagnostic instrument 14 to the hybrid vehicle. In a second time period, the exhaust analyzer 15 of the oil vehicle and the dynamometer 10 work together, and at this time, the worker connects the exhaust analyzer 15 to the hybrid vehicle. The first time period and the second time period can be the same or different, which is not limited herein.

[0127] The diagnostic instrument 14 and the exhaust analyzer 15 are pre-connected to the dynamometer 10, which can be compatible with different types of detected vehicles for detection, etc., and can also improve the detection efficiency, etc.

[0128] In some embodiments, the diagnostic instrument 14 of the new energy vehicle and the exhaust analyzer 15 of the oil vehicle are both in communication connection with the dynamometer 10. The identifier 201 is further configured to identify information of a next vehicle to be detected during a current vehicle detection process. The controller 202 is further configured to, in response to the current vehicle to be detected being a pure electric vehicle and the next vehicle to be detected being a pure oil vehicle or a hybrid vehicle, send a prompt instruction for prompting a staff to connect the exhaust analyzer 15 of the oil vehicle to the next vehicle to be detected in advance; and in response to the current vehicle to be detected being a pure oil vehicle and the next vehicle to be detected being a pure electric vehicle or a hybrid vehicle, send a prompt instruction for prompting the staff to connect the diagnostic instrument 14 of the new energy vehicle to the next vehicle to be detected in advance.

[0129] In some embodiments, the diagnostic instrument 14 of the new energy vehicle and the exhaust analyzer 15 of the oil vehicle are both in communication connection with the dynamometer 10. The identifier 201 is further configured to identify information of a next vehicle to be detected during a current vehicle detection process. The controller 202 is further configured to, in response to the current vehicle to be detected being a pure electric vehicle and the next vehicle to be detected being a pure oil vehicle or a hybrid vehicle, send a prompt instruction for prompting a staff to connect the exhaust analyzer 15 of the oil vehicle to the next vehicle to be detected in advance; and in response to the current vehicle to be detected being a pure oil vehicle and the next vehicle to be detected being a pure electric vehicle or a hybrid vehicle, send a prompt instruction for prompting the staff to connect the diagnostic instrument 14 of the new energy vehicle to the next vehicle to be detected in advance.

[0130] The identifier 201 identifies information of a next vehicle to be detected in identifying information of a current vehicle to be detected. That is, the identifier 201 can identify information of the next vehicle to be detected in advance.

[0131] When the current vehicle to be detected and the next vehicle to be detected are of different types, the controller 202 prompts the staff to make corresponding operations in advance according to the information of the vehicles to be detected of different types in sequence.

[0132] In response to the current vehicle to be detected being a pure electric vehicle and the next vehicle to be detected being a pure oil vehicle or a hybrid vehicle, the controller 202 sends a prompt instruction and prompts the staff to connect the exhaust analyzer 15 of the oil vehicle to the next vehicle to be detected in advance.

[0133] In response to the current vehicle to be detected being a pure oil vehicle and the next vehicle to be detected being a pure electric vehicle or a hybrid vehicle, the controller 202 sends a prompt instruction and prompts the staff to connect the diagnostic instrument 14 of the new energy vehicle to the next vehicle to be detected in advance.

[0134] By identifying information of a next vehicle to be detected in advance through the identifier 201, the controller 202 responds to the information of the next vehicle to be detected and the information of the current vehicle to be detected in advance, so that the controller 202 prompts the staff to connect the exhaust analyzer 15 of the oil vehicle to the next vehicle to be detected in advance or to connect the diagnostic instrument 14 of the new energy vehicle to the next vehicle to be detected in advance, thereby improving the detection efficiency of the vehicle detection system 1000.

[0135] When the identifier 201 identifies that the information of the current detected vehicle and the next detected vehicle is the same, the controller 202 can not send the prompt instruction. For example, in the process that the identifier 201 identifies that the current detected vehicle is a pure electric vehicle, when the next detected vehicle is also identified as a pure electric vehicle, the controller 202 can not send the prompt instruction.

[0136] In some embodiments, the new energy vehicle diagnostic instrument 14 and the tail gas analyzer 15 of the oil vehicle are both in communication connection with the dynamometer 10. The identifier 201 is further configured to identify the information of the next detected vehicle in the process of detecting the current detected vehicle. The controller 202 is further configured to, in response to the current detected vehicle being a pure electric vehicle and the next detected vehicle being a hybrid electric vehicle, control the vehicle detection device 100 to first detect the hybrid electric vehicle in the fuel driving mode or the fuel power generation mode, and then detect the hybrid electric vehicle in the electric power driving mode.

[0137] In some embodiments, the new energy vehicle diagnostic instrument 14 and the tail gas analyzer 15 of the oil vehicle are both in communication connection with the dynamometer 10. The identifier 201 is further configured to identify the information of the next detected vehicle in the process of detecting the current detected vehicle. The controller 202 is further configured to, in response to the current detected vehicle being a pure electric vehicle and the next detected vehicle being a hybrid electric vehicle, control the vehicle detection device 100 to first detect the hybrid electric vehicle in the fuel driving mode or the fuel power generation mode, and then detect the hybrid electric vehicle in the electric power driving mode.

[0138] The identifier 201 identifies the information of the next detected vehicle in the process of identifying the information of the current detected vehicle. That is, the identifier 201 can pre-identify the information of the next detected vehicle.

[0139] When the current detected vehicle and the next detected vehicle are of different types, and the current detected vehicle is a pure electric vehicle and the next detected vehicle is a hybrid electric vehicle, the vehicle detection device 100 is first controlled to detect the hybrid electric vehicle in the fuel driving mode or the fuel power generation mode, prompting the staff to connect the tail gas analyzer 15 to the next detected vehicle; and then the vehicle detection device 100 is controlled to detect the hybrid electric vehicle in the electric power driving mode, prompting the staff to connect the diagnostic instrument 14 to the next detected vehicle.

[0140] By first detecting the hybrid electric vehicle in the fuel driving mode or the fuel power generation mode, and then detecting the hybrid electric vehicle in the electric power driving mode, the vehicle detection device 100 will not continuously detect tail gas when the next detected vehicle is a pure oil vehicle, reducing the measurement error of the sensor caused by continuous tail gas detection. It can be understood that, since the diffusion of tail gas in the air around the sensor needs a certain time, the tail gas analyzer 15 detects tail gas and the diagnostic instrument 14 detects three electric tests alternately, which is beneficial to waiting for the tail gas of the last detection to diffuse to the atmosphere sufficiently during the three electric tests, reducing the influence on the subsequent detection. In addition, the diagnostic instrument 14 and the tail gas analyzer 15 work alternately, which can reduce the wear and tear caused by the continuous work of the diagnostic instrument 14 and the tail gas analyzer 15.

[0141] In some embodiments, the diagnostic instrument 14 of the new energy vehicle and the exhaust analyzer 15 of the oil vehicle are both in communication connection with the dynamometer 10. The identifier 201 is further configured to identify information of a next vehicle to be detected during a current vehicle detection process. The controller 202 is further configured to, in response to the current vehicle to be detected being a pure oil vehicle and the next vehicle to be detected being a hybrid electric vehicle, control the vehicle detection device 100 to first detect the hybrid electric vehicle in an electric drive mode, and then detect the hybrid electric vehicle in a fuel drive mode or a fuel power generation mode.

[0142] In some embodiments, the diagnostic instrument 14 of the new energy vehicle and the exhaust analyzer 15 of the oil vehicle are both in communication connection with the dynamometer 10. The identifier 201 is further configured to identify information of a next vehicle to be detected during a current vehicle detection process. The controller 202 is further configured to, in response to the current vehicle to be detected being a pure oil vehicle and the next vehicle to be detected being a hybrid electric vehicle, control the vehicle detection device 100 to first detect the hybrid electric vehicle in an electric drive mode, and then detect the hybrid electric vehicle in a fuel drive mode or a fuel power generation mode.

[0143] The identifier 201 identifies information of a next vehicle to be detected in identifying information of a current vehicle to be detected. That is, the identifier 201 can identify information of the next vehicle to be detected in advance.

[0144] When the current vehicle to be detected and the next vehicle to be detected are of different types, and the current vehicle to be detected is a pure oil vehicle and the next vehicle to be detected is a hybrid electric vehicle, the vehicle detection device 100 is first controlled to detect the hybrid electric vehicle in an electric drive mode, prompting a staff to connect the diagnostic instrument 14 to the next vehicle to be detected; and then the vehicle detection device 100 is controlled to detect the hybrid electric vehicle in a fuel drive mode or a fuel power generation mode, prompting the staff to connect the exhaust analyzer 15 to the next vehicle to be detected.

[0145] By first detecting the hybrid electric vehicle in an electric drive mode and then detecting the hybrid electric vehicle in a fuel drive mode or a fuel power generation mode, when the next vehicle to be detected is a pure oil vehicle, the vehicle detection device 100 will not continuously detect exhaust gas, reducing the measurement error of the sensor caused by continuous exhaust gas detection. In addition, the diagnostic instrument 14 and the exhaust analyzer 15 work alternately, which can reduce the wear and tear caused by continuous work of the diagnostic instrument 14 and the exhaust analyzer 15.

[0146] In some embodiments, the diagnostic instrument 14 of the new energy vehicle and the exhaust analyzer 15 of the oil vehicle are both in communication connection with the dynamometer 10. The identifier 201 is further configured to identify information of a next vehicle to be detected during a current vehicle detection process. The controller 202 is further configured to, in response to the current vehicle to be detected being a pure oil vehicle and the next vehicle to be detected being a hybrid electric vehicle, control the vehicle detection device 100 to first detect the hybrid electric vehicle in an electric drive mode, and then detect the hybrid electric vehicle in a fuel drive mode or a fuel power generation mode.

[0147] In some embodiments, the diagnostic instrument 14 of the new energy vehicle and the exhaust analyzer 15 of the oil vehicle are both in communication connection with the dynamometer 10. The identifier 201 is further configured to identify information of a next vehicle to be detected during a current vehicle detection process. The controller 202 is further configured to, in response to the current vehicle to be detected being a pure oil vehicle and the next vehicle to be detected being a hybrid electric vehicle, control the vehicle detection device 100 to first detect the hybrid electric vehicle in an electric drive mode, and then detect the hybrid electric vehicle in a fuel drive mode or a fuel power generation mode.

[0148] The identifier 201 identifies the information of the next detected vehicle in the information of the current detected vehicle. That is, the identifier 201 can identify the information of the next detected vehicle in advance.

[0149] When the current detected vehicle and the next detected vehicle are both the same type of vehicle, and are both the oil-electric hybrid vehicle, the current detected vehicle and the next detected vehicle have the same detection order.

[0150] For example, when the current detected vehicle is the oil-electric hybrid vehicle, the vehicle detection device 100 is first controlled to detect the oil-electric hybrid vehicle in the electric drive mode, and the staff is prompted to connect the diagnostic instrument 14 to the next detected vehicle; and the vehicle detection device 100 is secondly controlled to detect the oil-electric hybrid vehicle in the fuel drive mode or the fuel power generation mode, and the staff is prompted to connect the exhaust analyzer 15 to the next detected vehicle.

[0151] When the next detected vehicle is the oil-electric hybrid vehicle, the vehicle detection device 100 is first controlled to detect the oil-electric hybrid vehicle in the electric drive mode, and the staff is prompted to connect the diagnostic instrument 14 to the next detected vehicle; and the vehicle detection device 100 is secondly controlled to detect the oil-electric hybrid vehicle in the fuel drive mode or the fuel power generation mode, and the staff is prompted to connect the exhaust analyzer 15 to the next detected vehicle.

[0152] Alternatively, the vehicle detection device 100 is controlled to detect the current oil-electric hybrid vehicle in the fuel drive mode or the fuel power generation mode; and the vehicle detection device 100 is controlled to detect the oil-electric hybrid vehicle in the electric drive mode. Then, the vehicle detection device 100 is controlled to detect the next oil-electric hybrid vehicle in the fuel drive mode or the fuel power generation mode; and the vehicle detection device 100 is controlled to detect the next oil-electric hybrid vehicle in the electric drive mode.

[0153] When the current detected vehicle and the next detected vehicle are both the oil-electric hybrid vehicle, the fuel drive mode or the fuel power generation mode is executed at intervals with the electric drive mode, that is, the oil-electric detection is executed at intervals, so as to reduce the sensor measurement error caused by continuous exhaust detection. In addition, the diagnostic instrument 14 and the exhaust analyzer 15 work alternately, which can reduce the wear and tear caused by continuous work of the diagnostic instrument 14 and the exhaust analyzer 15.

[0154] In some embodiments, the pure oil vehicle can include, but is not limited to, the gasoline vehicle and the diesel vehicle. The gasoline vehicle has the fuel power generation mode. The diesel vehicle has the fuel drive mode. The exhaust analyzer 15 of the oil vehicle includes the five-gas analyzer 151 and / or the smoke meter 152.

[0155] The five-gas analyzer 151 is used to detect five gas components in the exhaust gas of a gasoline vehicle. The five-gas analyzer 151 is a conventional component in the art and is not limited herein. The smoke meter 152 is used to detect the smoke value in the exhaust gas of a diesel vehicle. The smoke meter 152 is a conventional component in the art and is not limited herein.

[0156] In some embodiments, the diagnostic instrument 14 of the new energy vehicle includes an insulation resistance tester. The insulation resistance tester is used to detect the insulation performance of the new energy vehicle. The insulation resistance tester is a portable electronic instrument specially used to measure the insulation resistance of electrical equipment, lines or insulation materials. The insulation resistance tester is a conventional component in the art and is not limited herein.

[0157] The above-mentioned insulation resistance tester can be connected with the diagnostic instrument 14 of the new energy vehicle through the first signal interface. The five-gas analyzer 151 and the smoke meter 152 can be connected with the corresponding five-gas analyzer 151 and smoke meter 152 through the second signal interface. That is, the five-gas analyzer 151 and the smoke meter 152 can share one second signal interface, and different five-gas analyzers 151 and smoke meters 152 are switched through plugging and unplugging.

[0158] In other embodiments, the signal interface includes a third signal interface (not shown in the figure). The second signal interface and the third signal interface are respectively configured to be able to connect the corresponding exhaust gas analyzer 15 and the smoke meter 152, etc.

[0159] Through the above-mentioned insulation resistance tester, five-gas analyzer 151 and smoke meter 152, etc., corresponding detection can be performed according to different types of vehicles to be detected.

[0160] It should be noted that the above-mentioned insulation resistance tester, five-gas analyzer 151 and smoke meter 152, etc. can be configuration pieces of the upgrade device 10a. Alternatively, the above-mentioned insulation resistance tester, five-gas analyzer 151 and smoke meter 152, etc. can be configuration pieces already existing in a vehicle detection site, which can improve the reusability and thus reduce the cost, etc.

[0161] Please refer to Figure 5 , Figure 6 , Figure 7 and Figure 8 , Figure 5 is a first partial side view of a vehicle detection device according to one or more embodiments; Figure 6 is a first partial top view of a vehicle detection device according to one or more embodiments; Figure 7 is a second partial side view of a vehicle detection device according to one or more embodiments; Figure 8 is a second partial top view of a vehicle detection device according to one or more embodiments. In combination with Figures 1 to 4In some embodiments, the wheelbase adjustment mechanism 13 comprises a driving member (not shown in the figure) and a plurality of connecting members 131. The plurality of connecting members 131 are arranged between the driving member and the mobile dynamometer 12. Each of the plurality of connecting members 131 is connected to the driving member at one end and connected to the mobile dynamometer 12 at the other end.

[0162] The driving member is configured to provide a driving force. The driving member can be, but is not limited to, a driving cylinder, a driving motor, or the like. The number of the plurality of connecting members 131 can be, but is not limited to, two or more than three. The plurality of connecting members 131 are arranged between the driving member and the mobile dynamometer 12. Each of the plurality of connecting members 131 is detachably or fixedly connected to a driving shaft of the driving member at one end and detachably or fixedly connected to the mobile dynamometer 12 at the other end. The driving member drives the plurality of connecting members 131 to move the mobile dynamometer 12.

[0163] The driving member, the plurality of connecting members 131, and the mobile dynamometer 12 work together to adjust the position change between the mobile dynamometer 12 and the fixed dynamometer 20, and the structure is simple and easy to operate and install.

[0164] In a specific embodiment, the number of the plurality of connecting members 131 is two. The two connecting members 131 are a first connecting member (not shown in the figure) and a second connecting member (not shown in the figure). The driving shaft of the driving member is connected to the first connecting member. The second connecting member is connected to the mobile dynamometer 12. The driving member drives the first connecting member to move closer to or away from the second connecting member, which can adjust the mobile dynamometer 12 to move closer to or away from the fixed dynamometer 20, thereby adjusting the wheelbase between the mobile dynamometer 12 and the fixed dynamometer 20. The first connecting member and the second connecting member can be, but are not limited to, gear driving, screw nut driving, slide rail driving, or the like, which are not limited herein.

[0165] In some embodiments, the bearing mechanism 11 comprises a bearing table 111 and a mobile fork tooth 112. The wheelbase adjustment mechanism 13 and the mobile dynamometer 12 are arranged on the bearing table 111. The mobile fork tooth 112 is arranged on a side of the wheelbase adjustment mechanism 13 away from the bearing table 111.

[0166] The bearing table 111 can serve as a basic support platform of the overall structure. The bearing table 111 provides installation positions for the wheelbase adjustment mechanism 13 and the mobile dynamometer 12.

[0167] By limiting the mobile fork tooth 112 to a position above the wheelbase adjustment mechanism 13, the mobile fork tooth 112 can play a certain bearing role and improve the overall strength of the equipment 10a. In addition, during the process of the mobile dynamometer 12 moving closer to or away from the fixed dynamometer 20, the length of the mobile fork tooth 112 along the first direction X also changes, thereby changing the wheelbase.

[0168] In an embodiment, the movable tines 112 are telescopic movable tines (not shown in the figure). The telescopic movable tines include a plurality of first movable tines 1121 and a plurality of second movable tines 1122. The plurality of first movable tines 1121 are connected to the bearing platform 111, i.e. the plurality of first movable tines 1121 are in a fixed state. The plurality of second movable tines 1122 are connected to the movable dynamometer 12 at one end of the wheelbase adjustment mechanism 13. When the wheelbase adjustment mechanism 13 drives the movable dynamometer 12 to move close to or away from the fixed dynamometer 20, the second movable tines 1122 can move close to or away from the adjacent first movable tines 1121, so as to adjust the overall length of the telescopic movable tines, etc.

[0169] Specifically, the plurality of first movable tines 1121 and the plurality of second movable tines 1122 are arranged along a second direction. The second direction can be perpendicular to the first direction. For example, the second direction can be the left-right direction. When the plurality of second movable tines 1122 move close to the plurality of first movable tines 1121, a second movable tine 1122 is inserted between two adjacent first movable tines 1121, so as to shorten the overall length of the telescopic movable tines. In addition, by inserting the second movable tine 1122 between the two adjacent first movable tines 1121, the risk of movement offset of the wheelbase adjustment mechanism 13 can be reduced, thereby improving the stability of the movement of the wheelbase adjustment mechanism 13.

[0170] In some embodiments, the upgrading device 10a is arranged at a position spaced apart from the fixed dynamometer 20. A support assembly 30 is arranged between the upgrading device 10a and the fixed dynamometer 20.

[0171] In this case, before the upgrading device 10a is installed at the vehicle testing site, the vehicle testing site already has the fixed dynamometer 20, and the upgrading device 10a only needs to be installed near the fixed dynamometer 20.

[0172] The upgrading device 10a is spaced apart from the fixed dynamometer 20. That is, the wheelbase adjustment mechanism 13 is spaced apart from the fixed dynamometer 20. The two can be connected or not connected. When the wheelbase adjustment mechanism 13 and the fixed dynamometer 20 are not connected, a hard material can be filled between the two to increase the strength between the two. When the wheelbase adjustment mechanism 13 and the fixed dynamometer 20 are connected, the two can be fixed by bolts, etc.

[0173] The support assembly 30 is arranged above the above-mentioned spaced-apart position, and the support assembly 30 can play a certain bearing role. The support assembly 30 is arranged flush with the surface of the upgrading device 10a and the surface of the fixed dynamometer 20, respectively. The space below the support assembly 30 can also be installed with other related structures, etc.

[0174] By repeatedly using the fixed dynamometer 20 of the vehicle detection site, the cost can be reduced and the space occupation can be reduced, etc. In addition, by the support assembly 30, the overall strength of the vehicle detection device 100 can be improved, etc.

[0175] In some embodiments, the fixed dynamometer 20 includes a first roller assembly 210. The mobile dynamometer 12 includes a second roller assembly 121. The wheelbase adjustment mechanism 13 is used to adjust the wheelbase between the first roller assembly 210 and the second roller assembly 121. Wherein the wheelbase between the first roller assembly 210 and the second roller assembly 121 is greater than or equal to 1920mm and less than or equal to 3400mm.

[0176] Wherein the first roller assembly 210 is used to drive the front axle or rear axle of the detected vehicle to rotate. The second roller assembly 121 can be used to drive the rear axle or front axle of the detected vehicle to rotate. The wheelbase adjustment mechanism 13 drives the mobile dynamometer 12 to move, and can adjust the wheelbase D between the second roller assembly 121 and the first roller assembly 210.

[0177] Wherein the wheelbase between the first roller assembly 210 and the second roller assembly 121 along the first direction X can be but not limited to 1920mm, 2000mm, 2100mm, 2200mm, 2300mm, 2400mm, 2500mm, 2600mm, 2900mm, 3000mm, 3200mm and 3400mm, etc.

[0178] By limiting the wheelbase range between the first roller assembly 210 and the second roller assembly 121, the vehicle detection device 100 can detect the detected vehicle that meets the above wheelbase, and improve the compatibility of the vehicle detection device 100, etc.

[0179] In a specific embodiment, the first roller assembly 210 includes a first sub-roller assembly 211 and a second sub-roller assembly 212. The first sub-roller assembly 211 and the second sub-roller assembly 212 are both extended along the second direction and spaced apart. The distance between the end of the first sub-roller assembly 211 close to the second sub-roller assembly 212 and the end of the second sub-roller assembly 212 close to the first sub-roller assembly 211 is 700mm. The distance between the end of the first sub-roller assembly 211 away from the second sub-roller assembly 212 and the end of the second sub-roller assembly 212 away from the first sub-roller assembly 211 is 2700mm.

[0180] The second direction can be, but is not limited to, a left-right direction. The first sub-roller assembly 211 and the second sub-roller assembly 212 are arranged in the left-right direction. The first sub-roller assembly 211 and the second sub-roller assembly 212 are arranged in the left-right direction with a spacing. The first sub-roller assembly 211 is located on the left side of the fixed dynamometer 20, and the second sub-roller assembly 212 is located on the right side of the fixed dynamometer 20. That is, the distance between the right end of the first sub-roller assembly 211 and the left end of the second sub-roller assembly 212 is 700 mm. The distance between the left end of the first sub-roller assembly 211 and the right end of the second sub-roller assembly 212 is 2700 mm.

[0181] By limiting the width of the first sub-roller assembly 211 and the second sub-roller assembly 212 in the second direction, the wheelbase of the oil car and the new energy car can be covered, and the compatibility of the vehicle detection device 100 is improved.

[0182] Similarly, the second roller assembly 121 includes a third sub-roller assembly (not shown in the figure) and a fourth sub-roller assembly (not shown in the figure). The third sub-roller assembly and the fourth sub-roller assembly are arranged in the second direction with a spacing. The distance between the end of the third sub-roller assembly close to the fourth sub-roller assembly and the end of the fourth sub-roller assembly close to the third sub-roller assembly is 700 mm. The distance between the end of the third sub-roller assembly away from the fourth sub-roller assembly and the end of the fourth sub-roller assembly away from the third sub-roller assembly is 2700 mm. By limiting the width of the third sub-roller assembly and the fourth sub-roller assembly in the second direction, the wheelbase of the oil car and the new energy car can be covered, and the compatibility of the vehicle detection device 100 is improved.
