Fig. 2 is the control method flow chart of heavy-duty car air-pressure brake helping air supply system according to embodiments of the present invention.
As shown in Fig. 2 this method includes：
A1, gas pressure sensor detects the gas pressure signal in air pressure braking system of automobile gas receiver, and this is believed
Number it is sent to single-chip microcomputer；
A2, single-chip microcomputer is judged according to the pressure signal of gas pressure sensor and the comparison of preset lower limit, judges gas storage
Whether cylinder pressure is too low, if so, then output control signal, controls motor operation；If it is not, circulated into next detection；
A3, under the control of A2 Absent measures signals, motor operation, the air compressor machine work of band dynamic auxiliary, carried for gas receiver
For assist gas pressure；
A4, in motor and the auxiliary air compressor machine course of work, single-chip microcomputer continues through gas pressure sensor detection storage
Air pressure signal in inflator, judges whether gas storage cylinder pressure has exceeded setting higher limit, if so, motor stalling is then controlled,
Helping air supply system stalls；If it is not, then control motor remains in operation, helping air supply system works on.
