the second step is that: when a driver steps on an accelerator pedal by more than 15% and the required torque is more than 200NM, the vehicle control unit controls a normally closed ASR solenoid valve to be powered off, the normally open ASR solenoid valve is powered on for 3s, gas in a rear brake chamber is exhausted, the automatic parking function is not effective, if a built-in voltage type air pressure sensor senses air pressure and outputs an electric signal, the vehicle control unit can report that a temporary parking system of the commercial vehicle is in fault, and P on an instrument flickers;
the third step: when the vehicle waits for a traffic light or temporarily stops at a stop, the control method is as described in the first step.
The utility model discloses following beneficial effect has: the utility model discloses on original [ electric ] motor coach air brake's basis, only increase interim parking module, this utility model easy operation, convenient to use. .
Description of the drawings:
fig. 1 is the utility model discloses temporary parking system's of commercial car structural schematic diagram.
Fig. 2 is a schematic diagram of the temporary parking module of the present invention.
The specific implementation mode is as follows:
the present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1, the utility model discloses interim parking optimizing system includes inflating pump 1, condenser 2, desicator 3, four return circuit protection valves 4, back braking gas receiver 5, brake pedal 6, interim parking module 7, bi-pass check valve 8, relay valve 9, ABS valve 10 and back brake chamber 11. One end of condenser 2 links to each other with inflating pump 1, the other end links to each other with desicator 3, the one end of four-circuit protection valve 4 links to each other with desicator 3, the other end links to each other with back braking gas receiver 5, the one end of brake pedal 6 links to each other with back braking gas receiver 5, the other end links to each other with the air inlet of bi-pass check valve 8, the one end of interim parking module 7 links to each other with back braking gas receiver 5, the other end links to each other with the air inlet of bi-pass check valve 8, the one end of relay valve 9 links to each other with the one end of bi-pass check valve 8, the other end links to each other with ABS valve 10, back.
As shown in fig. 2, the temporary parking module 7 of the present invention includes: a normally closed ASR solenoid valve 12, a check valve 13, a pneumatic switch 14 and a normally open ASR solenoid valve 15. One end of the check valve 13 is connected with the air outlet of the normally closed ASR solenoid valve 12, the other end is connected with the air inlet of the normally open ASR solenoid valve 15, and the air pressure switch 14 is located at the air outlet of the normally open ASR solenoid valve 15.
In the above embodiment, the temporary parking module 7 is controlled by the vehicle control unit, but as another embodiment, the temporary parking module may be controlled by a single controller.
In the above embodiment, the air pressure is detected using the air pressure switch in the temporary parking module 7, and as another implementation method, the air pressure sensor may be separately controlled.
In the above embodiment, a differential valve may be used instead of the two-way check valve and the relay valve.
In the above embodiment, the exhaust port of the normally closed ASR solenoid valve in the temporary parking module 7 is closed, and a check valve may not be used.
The working principle of the inflating pump 1, the condenser 2, the dryer 3, the four-circuit protection valve 4, the rear braking air cylinder 5, the braking pedal 6, the two-way one-way valve 8, the relay valve 9, the ABS valve 10 and the rear braking air chamber 11 is the same as that of the inflating pump, the condenser, the dryer, the four-circuit protection valve, the rear braking air cylinder, the brake master valve, the two-way one-way valve, the relay valve, the ABS valve and the rear braking air chamber in the air braking system of the passenger car in the prior art. The theory of operation is the same, and the event is no longer right the utility model discloses give unnecessary details.
The utility model discloses control method of interim parking optimizing system, the step is as follows:
the first step is as follows: when the vehicle is stationary after starting, the brake pedal 2s is depressed deeply. If the manual control valve is pulled up at the moment, the vehicle controller can acquire that the parking brake lamp has no signal output, and the normally open ASR electromagnetic valve 15 is controlled not to be electrified; if the manual valve did not pull up this moment, vehicle control unit can gather the parking brake lamp and have signal output, explain that the vehicle is not in the parking state this moment, then can control the circular close formula ASR solenoid valve 12 circular telegram 3s, the circular open formula ASR solenoid valve 15 is not circular telegram, the baroswitch 14 of the gas outlet department of the circular close formula ASR solenoid valve 12 has atmospheric pressure simultaneously, the output signal of telecommunication explains that automatic parking function is normal, "P" sign is also lighted thereupon on the instrument, gas can get into back brake air chamber 11 in the back braking gas receiver 5, the vehicle keeps the parking. If the built-in voltage type air pressure sensor does not sense air pressure or only has a small amount of air, the vehicle control unit can report the fault of the temporary parking system of the commercial vehicle, and the P-shaped meter flickers.
The second step is that: when a driver steps on an accelerator pedal by more than 15% and the required torque is more than 200NM, the vehicle control unit controls the normally closed ASR electromagnetic valve 12 to be powered off, the normally open ASR electromagnetic valve 15 is powered on for 3s, the gas in the rear brake chamber is discharged, and the automatic parking function is not effective. If the built-in voltage type air pressure sensor senses air pressure and outputs an electric signal, the vehicle control unit can report the fault of the temporary parking system of the commercial vehicle, and the P-shaped sensor flickers.
The third step: when the vehicle waits for a traffic light or temporarily stops at a stop, the control method is as described in the first step.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications can be made without departing from the principle of the present invention, and these modifications should also be regarded as the protection scope of the present invention.
