The opening and closing time of the three-way electric control electromagnetic valve is controlled by a program in the vehicle control unit, so that the three-way electric control electromagnetic valve can be better matched with a vehicle inflating pump to work, the requirement of the gas pressure value of a vehicle air storage cylinder is met, and the vehicle inflating work is finished.
Description
Technical Field
The invention relates to a vehicle function system, in particular to a vehicle inflation system.
Background
At present, in a whole vehicle, particularly a passenger vehicle, a medium-large vehicle, the air pressure value of an air cylinder of the whole vehicle is too low, an inflating pump starts to work, moisture is doped in air of an unavoidable surface in the inflating process, in order to reduce the moisture in the air cylinder, a dryer, a condenser and a blowback valve are additionally arranged in a chassis of the whole vehicle, when the pressure value in an air path is increased to a set value, the valve is pushed open through the air pressure to exhaust the moisture in an air pipeline, when the air pressure is reduced to the set value, the valve can be automatically closed, and the air path is closed and is not exhausted any more. The back-flushing valve generally adopts a mechanical back-flushing valve, on one hand, the pressure setting of the back-flushing valve is manual operation, and errors are easy to exist; on the other hand, because the installation position of the blowback valve is hidden, the set value of the blowback valve is high or low easily in the chassis when the batch vehicle is produced, so that the inflation and drainage of the whole vehicle are unstable.
Disclosure of Invention
The invention aims to provide an automobile inflation system, which can ensure that the whole automobile is inflated stably and the pressure is controlled accurately.
A dryer, a condenser and a three-way electric control electromagnetic valve are connected between an inflating device and a gas storage device, one passage of the three-way electric control electromagnetic valve keeps the inflating device, the dryer, the condenser and the gas storage device in a communicated state, and the other passage of the three-way electric control electromagnetic valve and the external environment is controlled to be opened and closed; the switch control electric signal of the inflation device, the pressure sensor signal of the gas storage device and the electric signal controlled by the three-way electric control electromagnetic valve are respectively connected with the vehicle control unit; the vehicle control unit is filled with a program which runs according to the following steps:
in a high-pressure state on the whole vehicle, if a pressure signal received by a vehicle controller from a pressure sensor of a gas storage device is not higher than a first pressure set value, the next step is carried out;
(II) the vehicle control unit sends a signal for opening a switch to the gas charging device, the gas charging device starts to charge the gas storage device, and the vehicle control unit sends a signal for keeping the switch opening state within a first set time value to the gas charging device when the vehicle control unit receives that the pressure signal of the pressure sensor of the gas storage device is not lower than a second pressure set value; when the vehicle control unit receives that the pressure signal of the pressure sensor of the gas storage device is not lower than the third pressure set value, the next step is carried out;
(III) the vehicle control unit sends a signal to the three-way electric control electromagnetic valve, and after the signal is communicated with the external environment to a second set time value, the communication with the external environment is closed; and D, when the first set time value in the step II is reached, the vehicle control unit sends a signal for closing the switch to the air charging device, and the air charging device stops charging the air storage device.
When the first pressure set value is 65-70% of the gas pressure value when the gas storage device is filled with gas, the second pressure set value is 90-91% of the gas pressure value when the gas storage device is filled with gas, and the third pressure set value is more than 95% of the gas pressure value when the gas storage device is filled with gas, the system works better.
When the first set time value is 30 seconds and the second set time value is 2 seconds, the inflation working performance is excellent.
Compared with the conventional whole vehicle inflation system and method, the three-way electric control electromagnetic valve is adopted, and the corresponding control program is added in the whole vehicle controller, so that the three-way electric control electromagnetic valve can be matched with the working time of the inflation device, the pressure value of the air storage device of the whole vehicle can be accurately set, meanwhile, the air can be exhausted and the moisture in the air path can be removed, the tedious work of repeatedly and mechanically debugging the inflation system during batch production of the whole vehicle can be avoided, and the working efficiency is improved.

Detailed Description
Example 1
A vehicular inflation system, the connection of each apparatus part is as shown in figure 1, connect with the dryer 3, condenser 4 and three-way electric solenoid valve 5 between inflator (inflating pump) 1 and gas storage device (air cylinder) 2, and a route of the three-way electric solenoid valve 5 keeps inflating pump 1, dryer 3, condenser 4 and air cylinder 2 in the communicating state, another route between the three-way electric solenoid valve 5 and external environment has control 5-1 of opening and shutting; in this example, when the gas storage device 2 is filled with gas, the gas pressure value is 1080KPa, and an on-off control electric signal (i.e., a gas pump enable signal) of the inflation pump 1, a pressure sensor signal of the inflation pump 2, and an on-off control electric signal (i.e., a high level signal) of the three-way electric control solenoid valve 5 are respectively connected with the vehicle controller 6; the vehicle control unit is filled with a program which runs according to the following steps:
when the whole vehicle has high voltage, if the pressure signal of the pressure sensor of the air storage cylinder 2 received by the vehicle controller 6 is not high 750KPa, the next step is carried out;
(II) the vehicle control unit 6 sends a signal for opening a switch to the inflating pump 1, the inflating pump 1 starts to inflate the air storage cylinder 2, and when the vehicle control unit 6 receives a pressure signal of the pressure sensor of the air storage cylinder 2 and is not lower than 980KPa, the vehicle control unit sends a signal for keeping the opening state of the switch to the inflating pump 1 within 30 seconds; when the pressure signal of the pressure sensor of the air cylinder 2 received by the vehicle control unit 6 is not lower than 1030KPa, switching to the next step;
(III) the vehicle control unit 6 sends a signal to the three-way electric control electromagnetic valve 5, and after the signal is communicated with the external environment for 2 seconds, the communication with the external environment is closed; and when the set time of 30 seconds in the step II is reached, the vehicle control unit 6 sends a signal for turning off the switch to the inflating pump 1 to stop the work of inflating the air storage cylinder 2.
