Find by analysis, background technology there is problems in that
(1) it is difficulty with the wheel speed linear regulation needed when testing, and is difficulty with four different demands of wheel speed rotating speed.
(2) motor volume cause too greatly practical application is moved relatively difficult, experiment can only carry out in fixing place.
Utility model content
Problem to be solved in the utility model is: provide a kind of wheel speed fictitious load controller. This controller comprises four set sensor units, by the solenoid in sensor unit being given different PWM (PulseWidthModulation, pulse width modulation) signal control solenoid produce magnetic field, utilize magnetic field change drive wheel speed sensors export corresponding signal carry out wheel speed test.
This utility model solves the scheme of above-mentioned technical problem:
A kind of wheel speed fictitious load controller, for simulation test wheel speed in braking automobile controller test, including housing, signal input interface, surface-mounted integrated circuit, output signal terminal, wheel speed sensors and solenoid etc.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As it can be seen, this utility model is a kind of wheel speed fictitious load controller. Including signal input interface 1, housing 2, surface-mounted integrated circuit 3, case top lid 4, output signal terminal 5, screw 6, wheel speed sensors 7, solenoid 8.
Signal input interface 1 is embedded to be fixedly mounted on housing 2, and surface-mounted integrated circuit 3 is built-in to be arranged in housing 2; On surface-mounted integrated circuit 3, design has sensor unit, sensor unit to include solenoid 8 and wheel speed sensors 7.
Embedded fixed installation output signal terminal 5 in case top lid 4.
Signal input interface 1 connects surface-mounted integrated circuit 3 by wire; Meanwhile, output signal terminal 5 is joined directly together also by wire and surface-mounted integrated circuit 3.
Case top lid 4 is buckled on housing 2, and is tightened by screw 6, makes surface-mounted integrated circuit 3 be fixed in housing 2.
On surface-mounted integrated circuit 3, design has four set sensor units, and each sensor unit comprises solenoid 8 and wheel speed sensors 7. Wheel speed sensors 7 is arranged on the position of magnetic line of force generation of solenoid 8, utilizes pwm signal to produce magnetic field to control solenoid 8, utilizes the change in magnetic field to drive wheel speed sensors 7 to export corresponding signal. Four solenoids 8 drive signal arbitrarily to change, and adopt the frequency in any prescribed limit, input different signals, it is possible to test different wheel speeds respectively. Design in the present embodiment has four set sensor units, it is possible to design less or more sensor unit to test different number of wheel speed.
In conjunction with accompanying drawing 3,4,5, sensor unit is illustrated.
Solenoid 8 is device ripe in prior art, without this does targeted design in this utility model; Wheel speed sensors is also adopt device ripe in prior art, therefore repeats no more for them. In sensor unit, solenoid 8 is inputted wheel speed frequency control signal, solenoid will produce to change (the S/ arctic, the N/ South Pole, the S/ arctic, South Pole N) with the electromagnetic field inputting same frequency, the change in magnetic field can cause wheel speed sensors 7 to export specific change, such that it is able to export specific waveform in output signal terminal 5.
In this utility model, signal input interface 1 is responsible for receiving control signal, and control signal is sent by microprocessor ripe in prior art.
