Abstract
A system for preventing the error pedaling on accelerating pedal is composed of monitoring sensor, electronic control unit (ECU) and braking executor.
Description
Technical field
The present invention is a kind of inhibition system for error stepping on accelerator pedal, is meant in the driving process inhibition system of error stepping on accelerator pedal when implementing urgent service brake especially, belongs to running safety method field.
Background technology
The accident of maloperation happens occasionally in the running process, error stepping on accelerator pedal when particularly in emergency circumstances needing service brake (throttle), may cause serious property damage and personal injury consequence, be in an emergency or the unexpected emergency braking of front truck as the place ahead, panic and the faulty operation of back car chaufeur, but error stepping on accelerator pedal be should brake, rear-end impact or other serious consequences caused.There is document announcement Honda Motor company to develop a kind of intelligent brake system, this intelligent brake system is in vehicle traveling process, system can automatically measure the speed and the intensity of initial 5 to 10 glancing impacts of chaufeur down, and analyze automatically thus the motorist the braking custom and as data be stored in system computerized in.Occur unusual in case chaufeur is stepped on the speed and the intensity of brake pedal, in the time of accident such as may occurring knocking into the back, it is dangerous that system will rely on " memory document " autobrake that is stored in the system to be avoided, traffic accident such as help the motorist to avoid better to knock into the back, but require chaufeur at first must implement service brake, chaufeur glancing impact error stepping on accelerator pedal can't be discerned and dispose.
Summary of the invention
The present invention proposes a kind of inhibition system for error stepping on accelerator pedal, the core of technical scheme is the speed of monitoring the chaufeur step on the accelerator in real time, and according to the automobile real-time status, carry out logic operation and relatively differentiation, in case find the velocity anomaly of chaufeur step on the accelerator in vehicle traveling process, promptly judge the chaufeur maloperation, system implements the service brake measure moment, suppresses chaufeur maloperation consequence.
Though prior art is noticed driver drives vehicle braking habit problem, and with memory driver drives vehicle braking custom, abnormal operation to chaufeur in the driving process carries out intelligent decision and emergency handling, but prerequisite is a chaufeur must implement the service brake operation, if chaufeur should service brake but maloperation be step on the accelerator, prior art can't judge and handle.
The driving misoperation suppression system that the present invention proposes proposes acceleration pedal status techniques scheme in the monitoring running process first, compared with the prior art, has tangible creativeness and definite beneficial effect.
Accompanying drawing
Fig. 1 is the inhibition system for error stepping on accelerator pedal functional block diagram.
Fig. 2 is the control program diagram of circuit of inhibition system for error stepping on accelerator pedal.
Embodiment
With reference to the accompanying drawings the technical solution of the present invention and the specific embodiment are elaborated below.
Fig. 1 is the functional block diagram of inhibition system for error stepping on accelerator pedal, the air throttle of car condition monitoring can be selected speed sensor or angular velocity sensor for use, when throttle gate velocity of rotation or throttle gate backguy moving velocity are unusual, sensor transmits electric signal to electronic control circuit (ECU), ECU differentiates (identification is step on the accelerator or loosens acceleration pedal) to the direction of this signal, and according to the automobile driving speed signal, make logic determines, when identifying the unusual and automobile driving speed of step on the accelerator＞0, promptly judge the error stepping on accelerator pedal establishment, electronic control circuit immediately sends braking instruction, drive stop mechanism and implement service brake, finish the maloperation inhibit feature.
Fig. 2 is the control program diagram of circuit of inhibition system for error stepping on accelerator pedal electronic control circuit, after automobile electric switch key switch is connected, system gets and at first carries out self-check program after electric, system exception then sends alarm signal and halt system work, otherwise the watchdog routine of entering, monitoring has or not acceleration pedal velocity of rotation or throttle gate backguy moving velocity abnormal signal, no abnormal signal promptly turns back to next circulation, having abnormal signal then to carry out sense differentiates, judgement is open the engine or reduces the throttle opening signal that if reduce the throttle opening signal, program is back to next circulation, otherwise carrying out the automobile real-time speed differentiates, if car speed=0, program is back to next circulation, if car speed＞0, system sends continuous braking instruction at once, reduces at 0 o'clock until car speed and stops.
The automobile driving speed sensor of inhibition system for error stepping on accelerator pedal can utilize the autometer sensor signal or reinstall speed sensor, and sensor installation site and mode can be with reference to the installation site and the modes of automotive speed sensor.
Electrical controlled brake of traveling crane shown in brake actuator can adopt in Fig. 1 frame of broken lines, when the electronic control circuit (ECU) of misoperation suppression system when sending braking instruction, electrical motor 3 gets electric operation, duplex Hydraulic Pump 1 and 1 ' oil inlet suck braking liquid from master brake cylinder, oil outlet is exported high hydraulic brake fluid, check valve 2 and 2 ' stops high hydraulic brake fluid to reflux, and forms brake-pressure and makes automobile brake, finishes the service brake process.Braking procedure finishes Hydraulic Pump and shuts down, and the Hydraulic Pump natural leak descends brake cylinder high pressure brake fluid pressure fast, and braking is removed.
When chaufeur was implemented service brake, check valve provided accelerated passage for braking liquid, satisfied the mobile fast requirement of service brake braking liquid, and during brake off, the natural leak after Hydraulic Pump shuts down descends the brake cylinder internal pressure fast, and braking is removed.
