Abstract
The invention discloses a novel pneumatic brake system for a vehicle. The system comprises a parking brake device, a front brake device, a rear brake device, a brake main valve and an air source device, wherein the parking brake device comprises a parking air storage barrel, a parking brake valve and a two-way check valve. The system is characterized in that: an electromagnetic valve control device is arranged on a pipeline between the parking air storage barrel and the parking brake valve or a pipeline between the parking brake valve and the two-way check valve and is connected with a control main machine for controlling the action of the electromagnetic valve control device. When a key switch is at an ACC gear, the action of the electromagnetic valve control device is controlled by detecting the speed of the vehicle and the closing condition of a vehicle door and then the pneumatic brake system for the vehicle is controlled to automatically brake, so that a driver is not required to make judgment or take other measures through personal ability and experience, the vehicle is prevented from abnormally started, the safety of passengers is further ensured, and accidents are greatly reduced.
Description
Technical field
The present invention relates to vehicular pneumatic braking system, especially relate to a kind of can self-stopping new vehicle Pneumatic braking system.
Background technology
The vehicular drive process mainly is artificial operating process, minimize in order to ensure the error of vehicle in traveling process, mainly can set about from two aspects: the one, improve the professional qualities of chaufeur and the speed of response (being to respond the very first time that vehicle can send at the operating order of chaufeur) of vehicle itself, avoid causing the loss of personnel and property because of the error of operation; The 2nd, automatic process is set on vehicle, reduce driver fatigue intensity, make the energy of chaufeur concentrate condition of road surface.But answer urban construction portion car operation regulation to require and existing urban public traffic vehicles operation conditions, vehicle stop, key switch is in the ACC shelves, car door opening or when not shutting just starts the improper startup that vehicle is advanced, and causes the passenger to fall down or clothes, bag such as are pressed from both sides at take place unexpected quite a few.In order to stop above situation, just must in upper and lower passenger's process, make the starting state standardization of vehicle, after guaranteeing the car door safety shutdown, vehicle could be started to walk, this control program of present vehicle is by pilot control, have the danger of misoperation unavoidably, can better not guarantee passenger's safety.
Summary of the invention
In order to address the above problem, the invention provide a kind of vehicle stop, key switch is in the ACC shelves, can self-stopping new vehicle Pneumatic braking system during car door opening.
The technical scheme that the present invention is adopted for its technical matters of solution is:
A kind of new vehicle Pneumatic braking system, comprise holding brake device, preceding brake equipment, post brake device, braking main valve and compressed air source unit, described holding brake device comprises Parking air receiver, braking during standstill valve, bilateral check valve, it is characterized in that: on the pipeline between Parking air receiver and the braking during standstill valve, or the pipeline between braking during standstill valve and the bilateral check valve is provided with a magnetic valve controller, and described magnetic valve controller links to each other with a main control system.
Further, described magnetic valve controller is the open type two-position three way magnetic valve.
The invention has the beneficial effects as follows: between the Parking air receiver of vehicular pneumatic braking system holding brake device of the present invention and the braking during standstill valve or the pipeline between braking during standstill valve and the bilateral check valve be provided with a magnetic valve controller, this magnetic valve controller links to each other with a main control system, the speed of a motor vehicle and the close situation of the car door action that come control electromagnetic valve control setup of this main control system by detecting vehicle, and then control vehicle Pneumatic braking system self-actuating brake, need not chaufeur and rely on profile and experience to judge or take other measures, greatly reduce the generation of accident; Vehicular pneumatic braking system be at vehicle stop, key switch is in the ACC shelves, but car door opening or do not shut self-actuating brake when clipping to other object prevents the improper startup of vehicle, further guarantees passenger's safety.
Further, magnetic valve controller adopts the open type two-position three way magnetic valve, and is arranged on the pipeline between Parking air receiver and the braking during standstill valve or on the pipeline between braking during standstill valve and the bilateral check valve; When main control system is failure to actuate, during the electromagnetic valve no power, admission port and air extractor duct are UNICOMs, do not destroy the brake system of former car, when main control system moves, electromagnetic valve energising, admission port and exhausr port UNICOM, the parking brake loop air pressure of back is low excessively, and vehicle 4 wheel brake sheets are held tightly, finish brake; When main control system recovery virgin state was failure to actuate, electromagnetic valve also recovered often to open the group state, and specified operating air pressure is recovered in the parking brake loop of back, and vehicle 4 wheel brake sheets unclamp, and vehicle is removed braking state.
