Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model.
Fig. 1 is theory diagram of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, the testboard bay 100 of the PEPS system that this example provides mainly comprises each controller 101 of system, test load case 102, bus monitoring emulation tool 103, host computer 104.
Each controller 101 of system comprises the tested control module that PEPS system is main, i.e. PEPS controller, BCM controller, IMMO controller, Intelligent key, electronic steering lock and EMS controller.
Test load case 102, the main module of PEPS system testing stand, main being responsible for provides all input stimulus and drives load system, it is by controller rat tail 105 connected system controllers 101, by communication monitoring wire harness 106 and bus monitoring emulation tool 103, join, and connect working power by power supply wire harness.
The input stimulus that this test load case 102 provides comprises low effective excitation, effectively excitation of height, pulse excitation and the simulating signal excitation of system needs.It specifically can be realized by switch, corresponding effectively source, one end of switch, power supply, or significant level, the switch other end directly connects corresponding controllers by controller rat tail; Each driving source is all furnished with LED simultaneously, to indicate foment.
The driving load that test load case 102 provides comprises that the height of system needs drives, the low even load of driving.Specifically can carry out Reality simulation load by LED light, i.e. the drive end of a termination controller of LED, other end ground connection or power supply.Test load case 102 does not comprise large current load, and corresponding external-connected port is only provided, and the driving test for large electric current, needs external large current load.
Moreover this test load case 102 comprises reometer, can control by switch working current and the quiescent current of arbitrary controller in selective measuring system or system.
Thus, when specific implementation, test load case 102 mainly comprises five parts such as case box, front panel, rear panel, case internal burden and controller rat tail.
Front panel is arranged on case box, and it mainly combines, exports simulation combination, communication simulation combination, startup button etc. by power switch, reometer, input stimulus simulation and partly forms.Wherein, input stimulus simulation combination, output simulation combination, communication simulation combination are formed by corresponding circuit.
Rear panel is arranged on case box, and is matched and join with front panel by corresponding circuit, and it is mainly partly comprised of fuse box, test box connector, communication RS232 interface, spare interface etc.
Case internal burden is arranged in case box, mainly relay box, hummer etc., partly consists of.
Controller rat tail and test box connector join.
Bus monitoring and the network node artificial tasks of bus monitoring emulation tool 103 and host computer 104 common completion systems.Bus monitoring emulation tool 103 is specifically formed by corresponding functional circuit, and it is connected with test load case 102 networks by CAN/LIN communication monitoring wire harness 106, and joins by usb data line 107 and host computer 104 data.
The testboard bay based on PEPS system 100 that this example provides is when building, first system corresponding controllers is connect on the connector of controller rat tail 105 one end, controller rat tail 105 other ends are inserted on the test box connector groove on the rear panel of cabinet.
