Description

A kind of hybrid vehicle test-bed correspondence tray accepted way of doing sth test platform

Technical field

The utility model belongs to hybrid power automobile power assembly bench test technical field, relates in particular to a kind of hybrid power automobile power assembly test-bed correspondence tray accepted way of doing sth test platform.

Background technology

Mixed power electric car has gasoline engine and two kinds of power sources of motor, and hybrid power system has been concentrated the advantage of two kinds of power sources, is a kind of novel vehicle energy saving and green technology, has worldwide obtained paying close attention to widely and studying.With generating/electromotion integrated ISG (Integrated Starter Generator) motor, variator, battery control unit, HEV (Hybrid electric vehicle) system is the hybrid drive train of important component parts.

The hybrid power automobile power assembly test-bed is compared with common threst stand, needs the more more complicacies of parameter of gathering.Traditional engine bench test scheme all is based on a large amount of sensors, and the selection of these transducer calibrations, modulate circuit and the layout of sensor all require a great deal of time and energy, and expensive.In order to build advantages of simplicity and high efficiency hybrid power assembly key components and parts test macro, the most effectively scheme exactly through car load CAN network directly and each parts controller carry out communication, thereby accurately obtain the performance parameter of each parts.In addition, bench test is also need come accurate control load rotating speed of motor and torque according to engine operation condition.For the reliability and the accuracy of warranty test, the control of load motor is synchronous with the necessary strictness of the monitoring of each controller.For operating condition, the especially transient working condition of the real simulated power assembly system of on stand, trying one's best, stand requires to have good real-time response performance.Present engine bench test system response time can only reach Millisecond the soonest, can not well satisfy the requirement of dynamic test.

The utility model content

In order to solve the deficiency of prior art; The utility model proposes a kind of hybrid vehicle test-bed correspondence tray accepted way of doing sth test platform; Solve traditional too numerous and diverse problem of sensor-based test macro, satisfied the requirement of hybrid power automobile power assembly system dynamics test.

The technical scheme of the utility model is: a kind of hybrid vehicle test-bed correspondence tray accepted way of doing sth test platform comprises engine controller, ISG electric machine controller, entire car controller, super capacitor controller, load motor, electric machinery control device and PXI monitoring platform; The PXI monitoring platform inserts the CAN network of engine controller, ISG electric machine controller, entire car controller, super capacitor controller composition through the CAN interface card; The PXI monitoring platform inserts the Profibus bus of electric machinery control device through the Profibus interface card; Said PXI test platform is realized being connected of CAN interface card and Profibus interface card through the RSTI bus.

The entire car controller of the utility model inserts the CAN bus with battery tension, car load signal, state of starting operating, clutch pedal, gas pedal, brake pedal, neutral gear, GES.

The engine controller of the utility model inserts the CAN bus with admission pressure, intake air temperature, coolant water temperature, throttle position, lambda sensor, engine rotational speed signal.

The ISG electric machine controller of the utility model inserts the CAN bus with ISG motor torque, ISG motor speed, ISG busbar voltage, ISG bus current, controller temperature, ISG motor mode signal.

The beneficial effect of the utility model is: simplified the layout of engine bench test system, shortened the setup time before testing; Platform adopts PXI Embedded Real-Time controller as master controller, improves the timing accuracy and the response performance of system, satisfies the requirement of hybrid power automobile power assembly system dynamics test.
