Abstract
A full-automatic stationary braking logic device for modern motor-driven vehicles takes signals from speedometer and throttle unit and sends stationary braking signal when the speed is equal to zero. When driver put his foot on throttle pedal to start, it can automatically send signal to release brake.
Description
The invention belongs to the braking during standstill technical field of power actuated vehicle, is auto electroincs.
I learn that by the retrieval of driving various vehicles and carry out in State Patent Office power-driven road vehicle has only three kinds of methods if want the purpose that reaches braking during standstill at present, the one, slam foot-operated brake for a long time; The 2nd, tighten hand brake (also having foot-operated); The 3rd, gear is changed to park (vehicle of automatic transmission).And will remove braking during standstill the time, need the driver to make another corresponding action again, that is: decontrol foot-operated brake, or relieving hand brake, or gear changed to driving shelves, even state-of-the-art vehicle also needs the driver to double-click push button as the notion vehicle of new " the people's car one " released of MIT 9 years.Because above-mentioned parking braking method is all non-full automatic, so have the following disadvantages: the first, driver behavior is too loaded down with trivial details, greatly reduces the comfort of driving.The second, often cause the slide car, threaten traffic safety.
Purpose of the present invention, to design a kind of safer exactly, and can improve the full automaticity emergency brake system of driving comfort greatly, its key is " full automaticity ", promptly by a cover logic device, make self-propelled vehicle in whole driving process and behind the switch-off, need not that the driver makes any specialized operations and the purpose that reaches braking during standstill.
Technical scheme of the present invention is velometer, accelerator device and the Parking holding brake device that a cover logic device is connected to vehicle.When the moving velocity that records vehicle when velometer reduced to zero, this device started automatically, and the holding brake device of connection vehicle makes vehicle implement braking during standstill automatically; And when vehicle need be started to walk again, the driver pin is placed on the throttle in an instant, this device starts once more, makes vehicle remove braking during standstill, freely travels, thereby reaches the purpose of full automaticity braking during standstill.
Let us is selected a kind of more advanced vehicle at present, has promptly installed the automatic transmission car of anti-lock braking system additional.Below by the specific embodiment of the present invention on this vehicle, and the present invention is described further in conjunction with the accompanying drawings.
Accompanying drawing is the logical circuitry that the present invention is incorporated into above-mentioned vehicle.
It comprises following content: ● the output signal S of velometer, establish the speed of a motor vehicle when non-vanishing, S is a logical zero, when the speed of a motor vehicle was zero, S was a logical one.● the output signal ABS of antiblock device, when setting up defences the locking system works, ABS is a logical zero, during auto lock brake system malfunction, ABS is a logical one.● the output signal Y of accelerator device, when establishing pin and not setting foot on throttle, Y is a logical zero, when setting foot on, Y is a logical one.● the output signal P of whole logic device, when establishing P and being logical one, implement braking during standstill, when P is logical zero, remove braking during standstill.● first order AND circuit I, first order not circuit II, second stage AND circuit III.Vehicle is under the cruising state, and the speed of a motor vehicle is non-vanishing, and S is 0; Auto lock brake system malfunction, ABS are 1; Whether at this moment no matter refuel (no matter Y is 1 or 0), P one is decided to be 0.Whole device is in monitoring and treats state, does not implement braking during standstill.
When vehicle had been finished normal brake, the speed of a motor vehicle reduced to 0, and S is 1; Owing to be normal braking, auto lock brake system malfunction, ABS are 1; Y is 0 (brake non-refuelling); At this moment P becomes 1, makes vehicle implement braking during standstill rapidly, and the red light P on the control instruments platform lights simultaneously, informs that driver's braking during standstill finishes.No matter be that the vehicle original place is motionless on the level road or on sloping road this moment.The driver can have a rest to the greatest extent with loosening, wait for.You see, need not any specialized operations and have just finished braking during standstill.Easily, safety!
When vehicle need be started to walk again, the driver was as long as be placed on pin lightly on the Das Gaspedal, and at this moment trigger switch, Y become 1; S still is 1; ABS still is 1; P is becoming 0 in a flash, makes vehicle remove braking during standstill at once, enters motoring condition, and the red light P on the instrument desk extinguishes simultaneously.You see, need not any specialized operations change remove braking during standstill.
Here of particular note, vehicle is under emergency braking condition, and antiblock device is started working, and ABS one is decided to be 0; This moment, no matter S and Y were 0 or 1, and P one is decided to be 0, can not implement braking during standstill.Have only when antiblock device work to finish, ABS is the state that just returns to normal braking after 1.
The present invention is except being applicable to vehicle above-mentioned normal brake application state and emergency braking condition, also is applicable to the braking during standstill of vehicle parking after flame-out, this be because, at first, the state vehicle has been in normal brake application before flame-out after, braking during standstill is finished.Secondly, the power supply of this device is from automobile storage battery, and owing to be electronics package, power consumption is few, so this device still can keep vehicle to be in the braking during standstill state for a long time behind the switch-off, until igniting next time.
Again for an extreme example: vehicle is flame-out suddenly in the way of travelling.Because this device is by storage battery power supply, so still in running order, as long as the driver stops car, this device is still implemented braking during standstill.
May be thought of as the present invention a main supply switch is installed, so that the driver uses under special circumstances.Use up such as fuel, when needing to promote vehicle.
Can illustrate that in sum the present invention is applicable to the braking during standstill of modern automotive vehicle under various states.
The present invention also is applicable to modern various vehicle types, and is particularly important for motor omnibus and lorry.Because such vehicle is in case cause trouble the safety of life and property that will jeopardize more people.And for the different various vehicles of degree of automation, the present invention also is suitable for.Such as on manual vehicle, holding brake device is exactly a hand brake, and is not installing on the vehicle of antiblock device, then can the present invention be implemented by using advanced velometer (as the radar velometer).In addition, about the movement device after the P; The selection of switch parameter; The selection of velometer precision; And the problems such as anti-lock device that adopt any kind of type, all belong to peripheral techniques of the present invention, and be prior art, not at row explanation of the present invention.
Claims (2)
1. logic device that is used for the power actuated vehicle braking during standstill, it is characterized in that, when being zero, the speed of a motor vehicle can send the signal of implementing braking during standstill automatically, and when vehicle need be started to walk again, can send the signal of removing braking during standstill automatically, it is full-automatic that thereby the braking during standstill that makes power actuated vehicle is realized, need not the driver and make any special operational motion.
2. one kind as the described logic device of claim 1., it is characterized in that, main signal source obtains from the velometer and the accelerator device of vehicle.
