Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated, below describe only exemplarily and explain, any pro forma restriction is not done to the utility model.
As shown in Figure 1, be applied to the electronic brake system of commercial vehicle, it comprises electronic control unit ECU, electronic control unit has electronic parking switch 6, electronic control unit is by CAN data bus connection control unit and spring air chamber, control unit comprises clutch master cylinder 4, main valve 10, relay valve 1, relay valve 2 15, electromagnetic valve 1, electromagnetic valve 2 14, double-way check valve 13, and spring air chamber comprises service brake cavity 16 and braking during standstill chamber 17.This electronic brake system passes through air inlet or the venting of electronic parking switch 6 controlling spring air chamber, and realizes the data exchange to control unit by CAN data bus.
Electronic control unit also comprises emergency stop button 1, auxiliary slope start to walk button 3, of short duration parking button switch 2, ignition lock 7, electronic parking switch 6, emergency stop button 1, auxiliary slope are started to walk button 3, of short duration parking button switch 2, ignition lock 7 is integrated in electronic control unit, and button 3 that electronic parking switch 6, emergency stop button 1, auxiliary slope are started to walk, of short duration parking button switch 2, ignition lock 7 are connected to the microprocessor of electronic control unit by data line.Electronic control unit has signal acquisition module, the vehicle speed signal 8 of signal acquisition module collection vehicle, throttle signal 9, gearbox-gear signal 5, the signal of each sensor is carried out calculation process and operation result is changed into control signal to control the work of controlled object by electronic control unit.Electromagnetic valve 1 is connected to electronic control unit by data line, and data are sent to electronic control unit through sensor by electromagnetic valve 1, and the data after electronic control unit process send it back electromagnetic valve 1 again and carry out executivecontrol function.Electromagnetic valve 1 is connected with double-way check valve 13, electromagnetic valve 2 14, source of the gas 2 19 respectively by CAN data bus.Double-way check valve 13 is connected with main valve 10, source of the gas 1, relay valve 1 respectively by CAN data bus, and relay valve 1 connects service brake cavity 16 by CAN data bus.Electromagnetic valve 2 14 connects relay valve 2 15 by CAN data bus, and relay valve 2 15 connects braking during standstill chamber 17 through CAN data bus.
This electronic brake system is applied to commercial vehicle, and its principle of work is as follows:
(1) vehicle static parking: when vehicle learns that current vehicle is in halted state from vehicle speed signal 8, press electronic parking switch 6, the gas in the braking during standstill chamber 17 of spring air chamber discharges by system works, reaches braking during standstill effect; During release parking, ignition lock 7 is in " ON " position, deeply steps on clutch pedal and clutch master cylinder 4 is worked, and gearbox-gear signal 5 is not in neutral simultaneously, and pull-up electronic parking switch 6, electronic parking system will remove braking during standstill.
(2) vehicle dynamic emergency brake: vehicle in the process of moving, chaufeur presses electronic parking switch 6, electronic parking system can directly control parking system work and deal with this emergency situation, and braking during standstill warning light is in blink states always, until trip switch.
(3) the interim parking of vehicle: after vehicle runs into traffic signal lamp stopping, traditional park mode needs the gas bleeding off whole spring air chamber parking chamber 17 to realize parking.And this electronic parking system is when realizing interim parking, only need to press of short duration parking button switch 2 by the bleeder brake in the air inlet of service brake cavity 16 replacement braking during standstill chamber.Because the volume ratio service brake cavity in braking during standstill chamber is large, it is also larger that it consumes gas, therefore this electronic parking system is than the more environmental protection and energy saving of traditional parking system.
(4) automotive vehicle is fixed: when running into after traffic signal lamp stop, even if chaufeur does not step on brake pedal, and vehicle also can realize vehicle when braking also ensures vehicle driving up starting simultaneously can not slip car.Once step on the throttle, pedal obtains throttle signal 9, and brake system can discharge, and vehicle just can travel.Wherein, as automotive vehicle more than fixed mode continuous firing 5min in current drive cycle, and the gradient that more than cumulative activation 30min or vehicle stop in current drive cycle more than 21 ° time, system can fix from automotive vehicle the braking during standstill pattern that master mode is converted to Systematical control.
(5) automatic diagnosis of electronic brake system: the electronic control unit ECU of electronic brake system, by the data exchange of other control units such as the realization of CAN data bus and main valve 10, electromagnetic valve 1, electromagnetic valve 2 14, double-way check valve 13, carries out selfdiagnosis, the reading of data flow and the function setting of system by diagnostic equipment to system simultaneously.
The electronic brake system being applied to commercial vehicle of the present utility model, eliminates the hand brake valve on standard machinery formula emergency brake system, and carry out air inlet or venting control by a button switch to spring air chamber, system architecture is simple, easy to operate.The electronization that this electronic parking control system not only achieves braking during standstill controls, and the automatic parking that simultaneously can realize commercial vehicle is fixed or dynamic emergency brake.In addition, this controller being applied to the electronic brake system of commercial vehicle can also go to realize more functions relevant with parking by gathering the signals such as the speed of a motor vehicle, engine speed, throttle position, transmission neutral, clutch state.
The above is only be described preferred implementation of the present utility model; not that scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that the common engineering staff in this area make the technical solution of the utility model and improvement, all should fall in protection domain that claims of the present utility model determine.
