Description
Technical field
the utility model relates to a kind of controller of extended-range electric vehicle, is specifically related to a kind of distance increasing unit controller monitoring system.
Background technology
pure electric automobile uses electrical energy drive vehicle completely, in use can realize " no pollution ", deeply pays close attention to by everybody.But because the energy density of power battery of pure electric automobile is low, the continual mileage that result in pure electric automobile is short.Moreover due to charging equipment imperfection, so the development of pure electric automobile encounters larger resistance.In this case, the appearance of extended-range electric vehicle well solves this problem.
controller debugging is a process extremely loaded down with trivial details, consuming time.Traditional distance increasing unit ECU parameter matching generally adopts manual change control program, recompilates the mode downloaded.And traditional developing instrument is merely able to the parameter of Read Controller, and real-time is bad.Meanwhile, debugging acid is difficult to send control command in real time to controller, and this will make whole debug process very loaded down with trivial details, brings very big inconvenience to the debugging of distance increasing unit control system, extends match time, adds cost of development.
in order to meet automobile demand for control, in each controller, be all integrated with controller local area network (CAN, controller area network) module.CAN is the data communication protocol that current automobile generally uses.In automobile test, communicated with host computer by CAN, the Real-Time Monitoring to travel condition of vehicle can be realized.LabVIEW is the graphical programming language of Nat Instr Corp.'s exploitation, is easy to develop man-machine interactive program interface.By USBCAN capture card, the LabVIEW platform in host computer can collect the data in CAN.
Summary of the invention
for above-mentioned technical matters, the utility model proposes a kind of distance increasing unit controller monitoring system, this monitor system operation is simple, and cost is low, and host computer can Real-time Collection slave computer data can to slave computer sending controling instruction.
the technical solution of the utility model is: a kind of distance increasing unit controller monitoring system, comprise distance increasing unit controller, also comprise the host computer being provided with LabVIEW software platform, described host computer is connected with distance increasing unit controller by USBCAN capture card, and described host computer is used for Real-time Collection slave computer and is sent to the message data of CAN and sends control command.
further, described USBCAN capture card is connected with host computer by USB interface, is connected by the CAN module of high speed shielded twisted-pair cable with distance increasing unit controller.
further, described message data at least comprises the rotating speed of engine, throttle opening, engine temperature.
further, described distance increasing unit controller comprises single-chip microcomputer and respective peripheral circuit, and described single-chip microcomputer, by the simulating signal of Analog-digital Converter module acquires through conditioning, calculates output signal according to input signal and steering logic.
further, described input signal at least comprises: engine rotational speed signal, temperature signal, fuel level in tank signal, switching signal, electrokinetic cell busbar voltage and current signal.
further, described output signal at least comprises: engine choke and throttle control signal, transfer pump switching signal, engine start and stopping signal, pilot lamp signal.
the utility model has the advantages that:
1. this monitor system operation is simple, and cost is low, and host computer can Real-time Collection slave computer data can to slave computer sending controling instruction.
2. can realize the on-line debugging work of distance increasing unit ECU, reduce workload, reduce cost of development, shorten the distance increasing unit ECU construction cycle.
Accompanying drawing explanation
below in conjunction with drawings and Examples, the utility model is further described:
fig. 1 is the theory diagram of the utility model distance increasing unit controller monitoring system;
fig. 2 is the distance increasing unit ECU theory diagram of the utility model distance increasing unit controller monitoring system.
Embodiment
for making the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with embodiment also with reference to accompanying drawing, the utility model is further described.Should be appreciated that, these describe just exemplary, and do not really want to limit scope of the present utility model.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring concept of the present utility model.
embodiment:
below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described further.
as shown in Figure 1, a kind of distance increasing unit controller monitoring system, comprises distance increasing unit controller (ECU), CAN card and a computer (host computer).Host computer is equipped with LabVIEW software platform, is connected with ECU by USBCAN capture card.
fig. 2 is the theory diagram of distance increasing unit ECU, and ECU includes Freescale single-chip microcomputer MC9S12DP256B and ensures its peripheral circuit normally worked.Single-chip microcomputer is by the simulating signal of Analog-digital Converter module acquires through conditioning, and according to input signal and steering logic, single-chip microcomputer calculates output signal, and by specific module, control signal is sent to specific topworks.The main input signal of ECU has: engine rotational speed signal, temperature signal, fuel level in tank signal, switching signal, electrokinetic cell busbar voltage and current signal etc.Output signal mainly contains: engine choke and throttle control signal, transfer pump switching signal, engine start, stopping signal, pilot lamp signal etc.Wherein, electrokinetic cell busbar voltage and current signal are responsible for collection by power controller, and meanwhile, ECU is integrated with CAN communication module, can be real-time send data to host computer and accept the control command that host computer sends.
after ECU powers on, the monitored data of needs can be sent with the form of message, the rotating speed of such as now engine, throttle opening, engine temperature etc.After host computer LabVIEW receives the message that slave computer sends, corresponding parameter can be gone out according to the protocol analysis made, graphically show in real time, and data can be preserved in real time.
same, when in the distance increasing unit course of work, when needing it according to specific operating mode work, just need to send control command by the LabVIEW platform of host computer to slave computer.Such as need engine operation at specific rotating speed, just can send rotating speed of target by host computer, after ECU receives instruction, the data in refresh routine that will be real-time, according to present instruction work.In this manner, some relatively simple staking-out works can be completed.
this supervisory system can realize the on-line debugging work of distance increasing unit ECU, reduces workload, reduces cost of development, shortens the distance increasing unit ECU construction cycle.
