when the vehicle is in a non-driving state, the electromagnetic valve 2 is in a power-off state, at the moment, a P interface of the electromagnetic valve is communicated with an A interface, a P interface of the electromagnetic valve is communicated with a B cut-off interface, and a B interface of the electromagnetic valve is communicated with an S interface, wherein the S interface of the electromagnetic valve is used for deflating a pipeline, so that the air pressure of the pipeline between the three-way valve 6 and the electromagnetic valve 2 is released, the first interface and the third interface of the three-way valve 6 are ensured to; an air source reaches a right rear door outer emergency control valve 3-2, a left rear door outer emergency control valve 3-1, a left middle door outer emergency control valve 3-3, a right middle door outer emergency control valve 3-4, a left front door outer emergency control valve 3-5, a right front door outer emergency control valve 3-6, a driver position air release valve 4, a left front door inner emergency control valve 5-5, a right front door inner emergency control valve 5-6, a right middle door inner emergency control valve 5-4, a left middle door inner emergency control valve 5-3, a left rear door inner emergency control valve 5-1 and a right rear door inner emergency control valve 5-2 to reach a three-way valve 6 along a pipeline, a first interface and a third interface of the three-way valve 6 are communicated, the first interface and the second interface are stopped, a 7-1 to 7-6 door pump is in a ventilation state, at the moment, the passenger door is in a state of opening the passenger door in a non-inhibited mode, and if the emergency control valve is opened randomly, the passenger door is in a state of opening the passenger door rapidly within 8 seconds; the first interface and the second interface of the three-way valve 6 are cut off, and the ventilation state of the passenger door pump from 7-1 to 7-6 is ensured; the driver can open the passenger door through the air release valve 4 and the instrument desk electric control switch at the driver position; the driver's air bag seat interface 8 is always vented.
Another embodiment further provides a whole vehicle air path control method capable of inhibiting opening of multiple passenger doors, which comprises the following steps:
when a vehicle speed sensor detects that the vehicle speed is greater than a set speed threshold value, a vehicle controller controls an electromagnetic valve to be switched on, a vehicle power supply electromagnetic valve is in a power-on state, a P interface and an A interface of an
when the vehicle speed sensor detects that the vehicle speed is less than a set speed threshold value, the vehicle controller controls the electromagnetic valve 2 to be disconnected with a vehicle power supply, the electromagnetic valve 2 is in a power-off state, a P interface of the electromagnetic valve 2 is communicated with an interface A, the P interface is disconnected with an interface B, the interface B is communicated with an interface S, the interface S of the electromagnetic valve is used for deflating a pipeline, the air pressure of the pipeline between the three-way valve 6 and the electromagnetic valve 2 is released, the first interface and the third interface of the three-way valve 6 are ensured to be continuously communicated, the pipeline is ensured to; an air source in the vehicle air storage device 1 reaches emergency control valves 3-1 to 3-6 outside a vehicle, a deflation valve 4 at a driver position, emergency control valves 5-1 to 5-6 inside the vehicle reach a first interface of a three-way valve 6, the first interface and a third interface of the three-way valve 6 are communicated, the first interface and a second interface are cut off, passenger door pumps 7-1 to 7-6 are in a ventilation state, the passenger door pumps 7-1 to 7-6 are in a state of opening the passenger door in a non-inhibition manner, and if the emergency door control valves are opened arbitrarily, the passenger door is controlled to be in an opening state; the first interface and the second interface of the three-way valve 6 are cut off, so that the ventilation states of the passenger door pumps 7-1 to 7-6 are ensured; the driver opens the passenger door through the bleed valve 4 and the instrument desk electrical control switch at the driver's position.
