Description
Technical field
The utility model relates to the vehicle electrically controlling field, specifically, relates to a kind of heavy-duty car body control system functional test desk.
Background technology
In the past; The development& testing of body control system carries out on real vehicle; Software or hardware change back just need to verify on car load that immediately the shortcoming of this practice is to have change just need electric-control system be taken slightly to carry out functional verification on the car load, and is more consuming time; Improved R&D costs, and there has been potential threat in the car load electrical system.In addition, have a lot of specialized companies that one-stop control system analogue test platform is provided abroad, but mostly expensive and on transplanting, bigger limitation is arranged, and each producer is from the reason to technical know-how, the foundation of testing table is all accomplished voluntarily, and is externally open.This is the weak point of prior art.
The utility model content
The technical matters that the utility model will solve provides a kind of heavy-duty car body control system functional test desk, the actual motion environment of emulation electric-control system on vehicle, the various functions of test, assessment body control system.
The utility model adopts following technical scheme to realize goal of the invention:
A kind of heavy-duty car body control system functional test desk; Comprise testing jig, it is characterized in that: said testing jig is provided with emulator, and said emulator connects host computer; Said emulator comprises analog sensor and actuator, and said analog sensor is connected vehicle ECU with actuator.
As the further qualification to the present technique scheme, said analog sensor comprises common simulation amount output card, high speed analog output unit and digital isolation amount I/O card.
As the further qualification to the present technique scheme, said host computer is connected with said emulator through Ethernet.
Compared with prior art; The advantage and the good effect of the utility model are: actual electric circumstance of the complete simulating vehicle of the emulator of the utility model and vehicle ECU accomplish information interaction; Analog sensor can generate the required multichannel input signal of vehicle ECU; And in real time the vehicle ECU data message of gathering is uploaded to host computer, and actuator is accomplished the execution work of the control signal of output in real time to vehicle ECU, and host computer is accomplished the programmed control to emulation vehicle ECU input signal; Accomplish collection, the demonstration work of vehicle ECU being exported in real time the control signal of actuator simultaneously, and accomplish follow-up storage and analytical work test data.
