The ABS simulation system has a wheel speed signal by simulating the practical vehicle condition; therefore, the ABS simulation system can simulate the vehicle ABS control process truly, simulate various failures and check various mounting parameters.
Description
Technical field
The utility model relates to a kind of ABS analogue system, relates in particular to the signal generation generator of wheel speed under this ABS analogue system simulates real real vehicle condition.
Background technology
ABS simulation table wheel speed signal mostly is to adopt random waveform generation snap gauge to intend at present, and card takes place random waveform can only produce the corresponding sine wave of doing frequency change with velocity variations, and its amplitude remains unchanged always.In the real work, wheel speed signal changes by sinusoidal wave more than frequency that electronic device record back shows, its amplitude also changes with the variation of wheel speed, and the influence of the electromagnetism of gear ring rotation and other physical factor can make wheel speed signal show the phenomenon that leans forward behind the electronic device record in the actual vehicle condition simultaneously.Therefore the wheel speed simulating signal of random waveform generation card generation can not be simulated the wheel speed signal under all true vehicle conditions fully, this has serious test leak for detecting ABS product newly developed, have huge potential safety hazard on the vehicle if will be used in by the product of this imitative town system.
The utility model content
The technical problems to be solved in the utility model provides a kind of ABS analogue system, its wheel speed signal generator adopts physical construction, wheel speed signal under the true vehicle condition of utilization closed-loop speed control output, the variety of issue that automobile runs into during the simulation truth and the wheel speed that produces.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: this ABS analogue system comprises vehicle dynamic model, wheel speed signal generator, ABS control system, air-channel system, described wheel speed signal generator comprises gear ring, wheel speed sensors and servomotor, described gear ring is installed on the servomotor, described wheel speed sensors is over against the tooth of gear ring, and described servomotor is controlled by vehicle dynamic model.
As of the present utility model a kind of preferred, described wheel speed signal generator and air-channel system are installed on the vehicle bridge.
The utility model adopts technique scheme, and the ABS analogue system has had the wheel speed signal under the simulates real real vehicle condition, so the ABS analogue system can carry out emulation to the automobile ABS control procedure truly, simulates various faults, the various installation parameters of verification.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
Fig. 1 is the fundamental diagram of a kind of ABS analogue system of the utility model.
Embodiment
The utility model ABS analogue system comprises vehicle dynamic model, wheel speed signal generator, ABS control system, air-channel system.Vehicle dynamic model is set up a cover simulation software on computers, and data collecting card and the DC control DA card that mates with this simulation software is installed on computers; The wheel speed signal generator comprises gear ring, wheel speed sensors and servomotor, and gear ring is installed on the servomotor, and wheel speed sensors is over against the tooth of gear ring; The ABS control system comprises external ECU, current sensor, driving circuit for electromagnetic valve; Air-channel system comprises gas-holder, brake pedal, ABS solenoid valve, quick release valve, relay valve, brake chamber and wheel hub, and setting pressure table on gas-holder is installed a high precision baroceptor on each brake chamber.As Fig. 1, shown in, vehicle dynamic model output direct current signal control wheel speed signal generator makes servomotor work, servomotor drives gear ring and rotates, at wheel speed sensors place output wheel speed signal.This wheel speed signal passes to the ABS control system, and then the ABS control system removes to control air-channel system, and the vehicle dynamic model information of gathering the working condition of air-channel system is calculated simultaneously, and then does corresponding operation.Its frequency of waveform that the wheel speed signal generator adopts physical construction output not only change with the variation of speed and its amplitude also with velocity variations.External ECU accepts to obtain real wheel speed signal from the driven by servomotor gear ring, sends control signal through the ECU inter-process and drives the ABS solenoid valve.This type of drive can realize functions such as external ECU hybrid simulation, vehicle coupling, road data reproduction, fault simulation and ABS performance evaluation.The various wheel speed faults of simulation that can be more convenient, energy analog wheel speed sensors opens circuit, short trouble; Can accurately adjust the gap and the sensor offset amount of sensor; Can adjust the axial dipole field of gear ring.Transposing gear ring that can be more convenient; Be convenient to upgrading in the future simultaneously.
Wheel speed signal generator and air-channel system are installed on the vehicle bridge.Because the wheel speed signal generator needs more stable condition of work after adopting physical construction, so when placing the wheel speed signal generator, will select a kind ofly to lay steadily the parts that clamping is firm.The pith that vehicle bridge is formed as automobile, the effect of itself is exactly to lay various parts in the above and then be assembled into car, wheel just is mounted on the vehicle bridge in the reality, therefore with vehicle bridge wheel speed signal generator and air-channel system are installed and are made them be operated in one stably in the environment, avoid vibrations to bring interference for ABS emulation.By on vehicle bridge, adjusting the solenoid valve position, adjust length of trachea, add the modification auto model, can carry out match test to different automobile types, enlarge the usable range of ABS analogue system.
