Description

The invention relates generally to a testing system for a vehicle, in particular for a motor vehicle, to a method for testing a vehicle, and to a computer program.Test systems for motor vehicles as such are known. For example, test systems for the main examination of vehicles can be designed as test roads, which comprise a plurality of test stations at which the motor vehicle is examined with regard to the function of its individual components (for example the brakes, the chassis and the lighting system). During the main examination, these test stations can be approached by the motor vehicle one after the other. Each test station can be provided with a test device provided for the scope of testing there. A specific test device can be designed as a test device, e.g. as a brake test stand, and can output a (measurement) value for each wheel under test. After the test at this test device, the tester can proceed to the test at the next test station; regularly, he then no longer takes into account the test results obtained in the previous, passed test.Against this background, it is an object of the present invention to provide a test system which can assist the tester in the process of identifying safety-relevant deficiencies on the vehicle in particular more easily. In addition, it is an object of the present invention to provide a corresponding method for checking a vehicle and a corresponding computer program. Further preferred objects can be obtained from the advantageous effects described below.The object(s) is / are achieved by the subject matter of claim 1 and the further independent claims. The dependent claims represent preferred embodiments.According to one aspect, a test system for a vehicle is proposed, comprising a first test station having a first test device which is designed to obtain a first parameter value of a first component of the vehicle, a second test station, at least one display device assigned at least temporarily to the second test station, and a first control device which is designed to control the display device to display a first indication representative of the first parameter value if the display device is assigned at least to the second test station.The first indication can preferably comprise the second parameter value, which can be displayed on the display device of the second test station accordingly by activation by means of the first control device. Further, the hint may include a first graphic. For the purposes of the present disclosure, a graphic can comprise, for example, a symbol, a number, an image and / or a word.The test system can thus enable the tester to have the first parameter value again taken in front of the eye directly or indirectly at the second test station, in order to be able to determine the possible causes more efficiently and thus to obtain a more overall image of the safety of the vehicle. In particular, the inspector can be made aware in a simple manner according to the invention of a situation in which both the first parameter value and a second parameter value obtained in a further inspection station are at an end of a predetermined tolerance range. In this case, the verifier in conventional verification systems would consider each of the two verifications to be passed; he could thus comparatively easily overlook a potential safety risk.The present invention, on the other hand, can elegantly clarify to the inspector that further examinations are required in order to be able to exclude deficiencies. In another example, if the second test station includes a test station for visual testing of the vehicle, the tester may be reminiscent of the test potentially marginally passed at the first test station and selectively visually inspect the first component of the vehicle to provide a better image of the condition of the vehicle. That is, the inspector can check the vehicle de facto more accurately and integrally. The invention can make it possible for even little experienced or poorly trained testers to carry out the test quite reliably and in the process advantageously to develop itself.The fact that the first parameter value can be taken directly or indirectly in front of the eye again at the second test station, in order to be able to determine the possible causes more efficiently, can be used not only during a main examination but also during fault diagnosis / fault search in a workshop or during the preparation of a used vehicle for sale, so that the same can be sold as free of faults as possible. The invention can also be advantageous within the scope of what is known as a dialogue acceptance in the workshop, in which a workshop employee examines components of the vehicle in order to calculate the repair, repair or maintenance outlay.In one variant, the display device is fixedly installed on the second test station. The display device can in particular comprise a display ("display"), which is provided in a fixed manner in the region of the second test station (for example set up or attached to a wall or ceiling). If the second checking station comprises the second checking device described in more detail below, the display device can be part of the second checking device. The second control device can be integrated into the display device. Alternatively, it is conceivable that the display device is designed as a portable display device. Examples of suitable portable display devices are portable computers, in particular smartphones, tablets or notebooks. In this case, the display device can be connected to the first control device in a data-transmitting manner, at least if the display device is assigned to the second test station. The display device can be designed as a display and operating device and can comprise, in particular, a touchscreen.If the display device is fixedly installed on the second test station, the display device can be assigned exclusively to the second test station. In this case too, on the basis of the (software, in particular network, preferably direct) connection of the, in particular all, test devices (test devices) to one another, the information (i.e. the corresponding indication) can be displayed on the basis of the respectively at least one result of at least one upstream test / examination. In this case, a scheme can be followed which has either been established by the structural conditions already during the installation of the test system or which can be selected by the tester at the respective test station with respect to the vehicle tested there.If, on the other hand, the display device is portable, it can be assigned flexibly to different test stations (e.g. the first, second, third, fourth, fifth, sixth and / or seventh test station) of the test system, in particular that test station at which the motor vehicle is detected by means of the test system. This assignment can be realized by connecting the display device to the respective test device in a data-transmitting manner (in particular for transmitting the parameter value obtained at the respective test station). Such a connection can be implemented sequentially (i.e., with only one test station at a time) or simultaneously (i.e., with several of the test stations at the same time). If a plurality of display devices are provided in the test system, each of the test stations can preferably comprise at least one of these display devices.Preferably, the test system (in particular the second test station) can be designed to determine whether the vehicle is located at the second test station. This applies correspondingly to all other test stations described here. This determination can be carried out by means of the test system taking into account a predetermined test sequence (i.e. following the vehicle). Alternatively, the determination can comprise requiring a user input by means of which the vehicle examined at the respective examination station is to be manually selected. In response to this determination, the test system may be further configured to associate the portable display device with the second test station. This applies analogously to each further test station described in this disclosure. That is, for example, when the vehicle is at the third test station, this may be determined to subsequently associate the portable display device with the third test station. Parallel assignments to a plurality of test stations are likewise conceivable.In one variant, the test system further comprises a second control device which is designed to determine whether the first parameter value deviates in terms of absolute value at most by a predetermined first threshold value from a setpoint value for the first parameter value or from an end value of a setpoint value range for the first parameter value. In the latter case, the threshold value can be at most 30%, or at most 20%, or at most 10%, of the width of the desired value range. The first control device can be designed to, in response to the ascertainment by means of the second control device, actuate the display device to display the first indication if the display device is assigned to at least the second test station.If the first parameter value deviates in terms of absolute value at most by the first threshold value from the end value of the desired value range, the verifier can thus easily identify that the partial test at the first test station has just been passed as far. If, for example, the first checking device is a brake checking stand, the inspector can be informed by means of the display device that there is a slight lack of the checked brake in order to examine the brake or another part of the vehicle influenced by the brake in more detail at the second or another subsequent checking station, for example to inspect it more visually. Analogously, in the event of a deviation from the setpoint value, the verifier can be provided with an indication that the partial test at the first test station has been passed so well that minor deficiencies detected at the second (or another subsequent) test station are potentially unproblematic. The inspector may thus more easily, reliably, and efficiently inspect the vehicle.It has been said that the first control means can control the display device to display the first indication in response to the determination by the second control means. This can mean that, if the second control device has established the state in which the first parameter value deviates in absolute terms at most by the predetermined first threshold value from the setpoint value for the first parameter value or from the end value of the setpoint value range for the first parameter value, the display device is actuated by means of the first control device to display the indication. If, on the other hand, the second control device has not detected this state, it can conversely be provided that the indication is not displayed. It is understood that what has been said above with regard to the assignment of the display device also applies to this.An entire controller of the test system may be distributed among the plurality of controllers including the first controller, the second controller, a third controller, and all other controllers disclosed herein. The first control device is advantageously configured for direct data-transmitting connection to the second control device. In particular, the first parameter value and / or data representative of the indication can be transmitted via this connection. Such networking of the control devices (de facto integration into an overall control) offers a high degree of flexibility with regard to the testing of the vehicle. Most preferably, all control devices of the test system (in particular the first, second, third, etc. control device) are configured to be directly connected to one another in a data-transmitting manner in order to transmit test results together with the acquired parameter values. Direct may mean a connection which runs directly between two or more control devices or test stations each and not, for example, via a third data transmitter (for example a server).The test system can comprise, in addition to the first and second test device, a third, fourth, fifth, sixth and / or seventh test device. The third checking device can be provided at a third checking station, the fourth checking device can be provided at a fourth checking station, the fifth checking device can be provided at a fifth checking station, the sixth checking device can be provided at a sixth checking station to one another and / or the seventh checking device can be provided at a seventh checking station. The first inspection station and the second inspection station can be part of the same inspection line. The second test station can be arranged after the first test station in the (intended, also preferred) direction of travel of the vehicle. That is, when the test system is used as intended, the vehicle can move to the second test station after the first test station. The third test station can likewise be provided upstream of the first test station, with respect to the direction of travel. Preferably, the first, second, third, fourth, fifth, sixth and / or seventh test station can be configured separately from one another. This means that the invention provides, in fact, for a transmission of information (in particular the first parameter value) between different test stations in order to be able to display test results obtained at one test station (for example the first) at another of the test stations (for example the second test station). In this respect, the test system according to the invention can be intelligent and trainable in order to provide the indications preferably at the correct, corresponding location / test, in particular at the following locations: chassis test-brake test-visual test-wheel suspensions; exhaust gas-visual test of the exhaust system; chassis-light test.The first to seventh test devices can each be designed as one of the following devices, wherein preferably all test devices of the test system are different: a rapid lane tester, a chassis tester, a roller brake test stand, a plate brake test stand, an axle play tester, a light adjusting device, an exhaust gas test device (emission test device) or a driver assistance system test device (engl. Advanced Driver Assistance System, ADAS). The first test device is preferably a brake test stand, in particular a roller brake test stand or a plate brake test stand. Preferably, the second inspection station is or comprises an inspection pit or a lifting platform. The third test device is preferably a chassis tester.The first control device is preferably spatially spaced / removed from the location at which the first parameter value is obtained (namely the first test station); thus, the first control device can be part of the display device. The first control device can be provided at the second test station, in particular if the display device is fixedly installed at the second test station. The second control device, on the other hand, is preferably provided at the first test station; it can be correspondingly designed as part of the first test device.If the test system comprises the second test device, it can be designed differently from the first test device. In particular, the second checking device can be configured to obtain a second parameter value, different from the first parameter value, of a second component of the vehicle, different from the first component (generic). In a preferred variant, the second test device is designed as a chassis tester. The second component can thus be the chassis and / or comprise at least one strut. The second test device can be part of the third test station.Preferably, the third test station is arranged on the same side of the second test station as the first test station. Thus, information about the vehicle (in particular the first and the second parameter value) obtained both at the first test station and at the second test station can be taken into account during the test at the second test station. For this purpose, the third control device can be configured to determine whether the second parameter value deviates in terms of amount at most by a predetermined second threshold value from a setpoint value for the second parameter value or from an end value of a setpoint value range for the second parameter value. Furthermore, the first control device can be designed to, in response to the ascertainment by means of the third control device, actuate the display device to display a second indication on the display device if the display device is assigned to the second test station (and / or to the second test device).The second indication can be realized in that the first graphic is replaced or supplemented by a second graphic different from the first graphic. For example, if the first indication is configured as a first symbol (e.g., a graphical representation of the first component), the second indication may be configured as a second symbol (e.g., a graphical representation of the second component) different from the first symbol. The symbol can also be represented in the form of a traffic light. The second indication may comprise the second parameter value, in particular if the first indication comprises the first parameter value.What is stated below for the first test station can correspondingly apply to all other test stations.In one variant, the first (as well as the second, third, etc.) can be used. The test station, in particular the first (as well as the second, third, etc.) The control device can be configured to maintain the first (etc.) To acquire and store relevant information. Information relevant to the maintenance can be information about the wear or required maintenance and / or can comprise a use history of the first checking device.For example, the first checking device can comprise one or more sensors which count predetermined processes; if an associated threshold value is exceeded, the checking system can output information that maintenance is required. This can analogously apply to all components of the test system which are subject to wear, for example electric motors (wherein the threshold value can be a threshold value for a running time of the electric motors) and seals (threshold value, for example lifting cycles). The information relevant for the maintenance can be correspondingly stored in the control device associated with the respective test station.Furthermore, the test system can be configured to send the first and / or second parameter value to a computer system remote from the test system for storing the first or second parameter value. The remote computer system may be configured as a cloud-type computer system. Additionally disclosed herein is another system that includes the test system and the remote computer system. The information relevant for the maintenance of the respective test device can also be stored and / or evaluated in a cloud-based manner. This information can be made available to postholders.In a further variant, the test system comprises a storage device and the first test station is designed to store at least one test result obtained by means of the first test device in the storage device in a manner associated with the vehicle. In other words, the first parameter value can be assigned to the vehicle by means of the first control device and can be stored in this assigned form in the storage device. The storage device is preferably formed separately from each test station of the test system.As stated above, this can be carried out analogously for the second and all further parameter values described here. This allows vehicle state (as vehicle state history) data to be generated and saved to generate a vehicle health record that can be used downstream. This may allow a service shop to reduce storage costs by delivering spare parts at the right time. In this case, in particular, accessible data can be read out from the vehicle's OnBoardDiagnostik, OBD, system and assigned to the vehicle.The test system can store the obtained parameter values, preferably in the test device at which the respective parameter value has been obtained. For example, the test system can store the first parameter value in the first test device, the second parameter value in the third test device, etc. Furthermore, the test system can interpret these parameter value(s) themselves downstream and / or output the described indications if the parameter values are close to the (calculated) final value (limit value). In this case, the deviation denotes closely which is less than the associated threshold value. The same applies analogously to the chassis test, exhaust gas test and light test.The method proposed here for testing a vehicle by means of the test system described above comprises the following steps, which are preferably carried out in the following sequence: arranging the vehicle at the first test station; obtaining the first parameter value by means of the first test device; displaying the first indication on the display device if the display device is assigned at least to the second test station.Moreover, this method may include any of the features described above in connection with the inspection system. In particular, the method can contain any desired functions of the test system and its components as method steps.The computer program contains instructions which, when the method is executed by the test system described in detail, cause the test system to execute the method. The commands can be provided in particular in order to have the control devices of the test system, in particular the display device(s), control according to the method.The computer program is stored on a computer-readable medium disclosed here, for example a data carrier (e.g. a hard disk or a USB stick).The computer readable medium may form or comprise the above-described storage device. The data stored there (so-called vehicle health data) can be made available to the vehicle again de facto in this way. This allows the manufacturer of the vehicle (for example wirelessly ("over the air")) and / or buyer of the used car to access these data, for example by means of an OBD reader.In an independent form, a checking device (in particular one of the first to seventh checking devices) for a checking system is also disclosed here, which is designed to obtain the first parameter value of the first component of the vehicle, to generate data representative of the parameter value and to transmit this data to a (first) control device. This test system may comprise any further features of the test system described above.Furthermore, a test system having a storage device and a first test device is disclosed in an independent form, wherein the storage device is designed to store at least one test result obtained by means of the first test device in the storage device in a manner associated with the vehicle. This test system may comprise any further features of the test system described above. In particular, the storage device and / or the first test device can be configured as described above.Moreover, a test system with a test device is disclosed in an independent form, which has a control device (for example the first) which is configured to acquire and store information relevant for a maintenance of the test device. Information relevant to the maintenance can be information about the wear or required maintenance and / or can comprise a use history of the first checking device. The information relevant for the maintenance can be correspondingly stored in the associated control device. This test system can also comprise any other features of the test systems described above. In particular, the test device can be designed as one of the above first, second, third, etc. test devices.In other words, the present invention relates to a test system in which the devices of the test site environment (i.e., the test facilities) are networked together so that the result of a test method provided by a device (a test facility) is displayed to the tester as an indication in a downstream test method (i.e., in a downstream test station).In one variant, a first test on the vehicle is the chassis test. There, each individual wheel (axle type) can be approached with different frequencies in such a way that the wheel oscillates up and down. The result of the test may be within the predetermined criteria (limits for passing the test) so that the vehicle passes this test. However, if there are abnormality (e.g., unusual sound that may indicate future damage) in this first test, this may be displayed on the lifting platform or on the pit to the tester during the visual test (so-called road fitness test) that occurs later on on on a display. The inspector can thus be assisted in examining the vehicle efficiently and thoroughly. Caused by the display, the inspector can then take the chassis components into view once again (better). This can increase the traffic safety of the vehicle.In another example, if a vehicle fails the front-left landing gear test and the front-left brake test is still just passed when considered by itself, the combination of poor ground contact and poor brake on the same wheel may be important for safety. The test system can reminder the tester by means of the indication thereof. The same applies to the exhaust gas test and the visual test in such a way that unusual but sufficient values output the indication during the visual test that, for example, the exhaust system could leak. Analogously, parameter values obtained in all other test devices can lead to a corresponding indication at the second test station.Moreover, downtime of the test system or of the individual test devices can be reduced by recording and analysing data about the use of at least one of the test devices (test devices). These data can be collected and used for predictive maintenance.Using the example of a (scissors) lifting platform (second test station), it is possible to record how many lifting and lowering cycles the lifting platform has completed and / or how much time has elapsed since the installation of the lifting platform. Then, the inspection system may be configured to inform that the aerial lift has to be serviced after a predetermined number of cycles (e.g., 10,000 cycles reached) or after a predetermined period of time since installation (e.g., 12 months), whichever occurs first. The maintenance / testing may include, for example, testing the tightness of the cylinders, valves and / or hoses of the lifting platform. In addition, the test system can comprise a maintenance plan which can provide that the joints of the lifting platform are greased. The maintenance plan can furthermore indicate where the lubrication points are located, that bolts and their guidance / bearing have to be checked and / or that the oil and the filters have to be replaced.Advantageously, by means of the present test system, state and / or diagnostic data of the tested vehicles can also be used and / or analyzed. Via the chassis number (engl. A "Fahrzeuggesundheitsakte" may be created Vehicle Identification Number, VIN). Either when checking in for the checking process or when reading out data via the OBD interface of the vehicle, the vehicle (not the holder) can be identified. The vehicle then runs through individual or all tests. The test results may then be stored along with the timestamp, the publicly available diagnostic data from the OBD and the vehicle. If the test system / test devices are already used in an end-of-line test in the delivery unit of the vehicle and then in the obligation tests of the main test, a vehicle health record or data about the state of many (safety-relevant and environment-relevant) components of the vehicle "crad-le2cradle" can be generated.The present invention thus advantageously makes it possible to use data which are obtained anyway. Furthermore, the invention can protect the environment, prevent accidents and increase safety on roads worldwide. Due to the shorter downtime and the indications, the test process can be carried out more quickly, more efficiently and nevertheless comparatively favorably.Preferred embodiments of a test system and a method for testing a vehicle will now be explained in more detail with reference to the attached schematic drawings, wherein FIG. 1 shows a variant of a test system, wherein the vehicle is located at the first test station; FIG. 2 shows the test system of FIG. 1 with the vehicle at the second test station; FIG. 3 shows a further variant of a test system, wherein the display device is portable; FIG. 4 shows a further variant of a test system in a system which comprises a computer system remote from the test system for storing parameter values; FIG. 5 shows a further variant of a test system which has a plurality of test lines; and FIG. 6 shows a method for checking a vehicle.FIGS. 1 and 2 show a test system 10 for a vehicle 12, the test system being designed as a test line P and comprising a first test station 20 and a second test station 30; it can furthermore have, as illustrated, a third test station 60, a fourth test station 80, a fifth test station 84, a sixth test station 88 and a seventh test station 92. The second test station 30 is provided after the first test station 20 in the direction of travel F. Each of the test stations mentioned can comprise at least one test device from the following group: a quick track tester, a chassis tester, a brake test stand (in particular a roller brake test stand or a plate brake test stand), an axle play tester, a light adjusting device, an exhaust gas test device or a driver assistance system test device. The first test station 20 is provided with a first test device 22, which is preferably designed as a brake test stand, in particular a roller brake test stand.The first checking device 22 is designed to obtain a first parameter value of a first component 14 (here a front wheel brake) of the vehicle 12.The second test station 30 comprises an inspection pit or a lifting platform 32 for visual inspection of the vehicle 12, in particular of the first component 14. Thus, in this variant, the display device 40 is permanently assigned to the second test station 30. A further display device 42 to 47 can be provided at the first and third to seventh test stations; the further display devices 42 to 47 can function analogously to the display device 40.In addition, the test system 10 comprises a first control device 50, which can be arranged at the second test station and / or designed to control the display device 40 to display a first indication 41 representative of the first parameter value. In the present case, the first indication is a symbol. It is conceivable, for example, to implement the symbol as a graphical representation of the first component 14 (vehicle brake). Thus, the tester 11 at the second test station 30 is alerted to a test result obtained at the first test station 20. For this purpose, the checking system 10 further comprises a second control device 52, which can transmit data representative of the first parameter value, on the basis of which the first indication is displayed, to the first control device 50. The second control device 52 is provided here at the first checking station 20.Advantageously, the second control device 52 is designed to determine whether the first parameter value deviates in absolute terms by at most a predetermined first (preferably relative) threshold value from a setpoint value for the first parameter value or from an end value of a setpoint value range for the first parameter value. The first control device 50 is accordingly designed to actuate the display device 40 in response to the ascertainment by means of the second control device 52, to display the first indication 41 (in the present case symbolically a exclamation sign) when the display device 40 is assigned at least to the second checking station 30. If the threshold value is, for example, 20% of the width of the setpoint value range for the braking force of the front wheel brake, the first indication is thus displayed if the first component 14 has passed the test at the first test station very closely. In this way, the verifier 11 can be provided with an indication that the first component 14 is to be viewed in more detail once again at the second checking station 30 (see FIG. 2 ).As shown in FIGS. 1 and 2, the inspection system 10 may further include a third controller 53 at the third inspection station 60, a fourth controller 54 at the fourth inspection station 80, a fifth controller 55 at the fifth inspection station 84, a sixth controller 56 at the sixth inspection station 88, and a seventh controller 57 at the seventh inspection station 92. The test system 10 can be designed to determine at which of the test stations 20, 30, 60, 80, 84, 88, 92 the vehicle 12 is currently located and to display data obtained at all test stations on the display device of the test station there, in order to provide the tester with an overall overview of the state of the vehicle 12.The test system 10 can comprise a second test device 62, different from the first test device 22, for obtaining a second parameter value of a second component 16 of the vehicle 12 different from the first component 14. As shown in FIGS. 1 and 2, the second inspection device 62 is provided at the third inspection station 60. The third control device 53 is configured to determine whether the second parameter value deviates in absolute terms by at most a predetermined second threshold value from a setpoint value for the second parameter value or from an end value of a setpoint value range for the second parameter value. The first control device 50 is designed to control the display device 40 to display a second indication on the display device 40 of the second test station 30 when the display device 40 is assigned to the second test station 30, in response to the ascertainment by means of the third control device 53. The mode of operation for generating the second indication thus corresponds to the mode of operation for generating the first indication 41, wherein the first indication 41 relates to the first component 14 of the vehicle 12 and the second indication relates to the second component 16 (chassis or strut) of the vehicle 12.The inspector 11 can thus have to be presented with eyes during the visual inspection that the first or the second component 14, 16 have just passed the respective individual inspection, can specifically search for defects in the associated vehicle region during the visual inspection and then optionally request repairs.As illustrated in the figures, a fourth test device 81 (here: lane tester, in particular a fast lane tester), a fifth test device 85 (light adjusting device), a sixth test device 89 (exhaust gas / emission measuring device) can be provided at the fourth test station 80, and / or a seventh test device 93 (driver assistance system test device) can be provided at the seventh test station 92. At the second test station 30, a further test device 33 in the form of an axle clearance tester is also provided. Test data obtained from each of these test stations can be displayed on the display device of the respective downstream test stations in a representative manner via indications, in a similar manner to the display at the second test station 30.The first test station 20 is advantageously configured to acquire and store information relevant for a maintenance of the first test device 22, such that maintenance measures can be better planned. This applies accordingly to all test stations 30, 60, 80, 84, 88, 92 present. Furthermore, the test system 10 comprises a storage device 94 in which test data obtained by means of the test stations, in particular the first parameter value and the second parameter value, can be stored assigned to the vehicle 12.A test system 10 for a vehicle 12 shown in FIG. 3 according to a modification differs from the test system 10 from FIG. 2 in that the display device 40 is portable (here, for example, embodied as a tablet). This display device 40 is connected to the first control device 50 in a data-transmitting manner when the display device 40 is assigned to the second checking station 30. Advantageously, the second test station 30 is configured to recognize that the vehicle 12 is located in the region of the second test station 30 in order to actuate this assignment. Instead of the permanently installed display device from FIG. 1, the portable display device thus comes in this variant. Moreover, the test system 10 according to FIG. 3 comprises all the features of the test system 10 from FIGS. 1 and 2.A further test system 10 shown in FIG. 4 differs from the test system 10 from FIG. 3 in that the former is configured to send the first parameter value to a (cloud-like) computer system 70 remote from the test system 10 for storing the first parameter value. Furthermore, both the second parameter value and all other test results obtained at the test devices 22, 33, 62, 81, 85, 89, 92 of the test system 10 can be transmitted from the test system 10 to the remote computer system 70. The test system 10 and the remote computer system 70 form a further system, denoted by the reference numeral 200. In addition, the test system 10 according to FIG. 4 comprises all features of the test system 10 from FIG. 3.A test system 10 according to FIG. 5 differs from the test system 10 from FIG. 1 in that the former comprises a plurality of test lines which preferably run parallel to one another. A first test line shown on the left in FIG. 5 comprises the test devices of the test line from FIG. 1, wherein the sixth test device 89 (exhaust gas / emission measuring device) is absent; this is transferred to the test line shown on the right in FIG. 5, in which neither lane tester nor light adjusting device are provided in turn. Moreover, the test system 10 from FIG. 5 comprises all features of the test system 10 according to FIG. 1.FIG. 6 shows a method 100 for checking a vehicle 12 by means of a checking system 10 according to one of FIGS. 1 to 5. Then, the first parameter value is obtained by the first checking means 22 (step 104). Step 106 further provides for the first indication 41 to be displayed on the display device 40 if the display device 40 is assigned to at least the second checking station 20. In addition, the method 100 can have the functional features of the test system 10 described above in connection with FIGS. 1 to 5 as additional method steps.In the context of the present disclosure, the terms "comprising", "having", "with" and the like are to be understood as non-exhaustive. Further, for convenience in reading, the term "at least one(s)" is partially omitted in this disclosure. If a feature is described in the singular, its plurality is also simultaneously meant. In the present case, at least temporarily means temporarily or permanently. The parameter values can be measured values (measurement results) of the respective test device.All the above-described final values can be calculated by means of the test system and / or stored, in particular predetermined, in the test system. The above numbering of the components (for example "first checking device") serves merely to distinguish these components. In particular, the numbering does not define an order of the inspection devices along the inspection line. Thus, for example, the first checking device can be arranged after the third checking device in the direction of travel along the checking road.
