Description
Technical field
The present invention relates to automobile safety electronic product, more particularly to a kind of control method of Anti-mis-stepping dead-man's device.
Background technology
Automotive safety is divided into two broad aspect of active safety and passive security for the vehicle.
Active safety is just to try to manipulation control automobile freely.Braking either on straight line is beaten with acceleration or left and right
Direction all should be as far as possible steady, is unlikely to deviate set route of travel, and do not influence the visual field and the comfort of driver.So
Automobile, just have certainly comparison it is high avoid accident ability, still it ensures automotive safety under conditions of emergency case.
Passive security refers to protection of the automobile to passenger after generation accident, the concept of nowadays this protection and
Extend to the outer all people of in-car even object.Since international automobile bound pair has had very detailed test in passive security
The regulation of details, so to a certain extent, passive security can quantify.
The scope that automotive safety technology is related to is increasingly wider, increasingly thinner, and towards integrated, intelligent, systematization, complete
The direction of memberization is developed.
(1) it is integrated：Automobile active safety technology is merged with passive security technology, preferably safety is obtained and protects
Protect effect.
(2) it is intelligent：Following automobile is mobile computer platform, and intelligent brake, intelligence are slowed down and automated steering will be
The essential characteristic of following intelligent automobile, GPS (global positioning system) technology, intelligent collision prevention system, intelligent driving system, intelligence wheel
The equipment such as tire, intelligent suspension, smart airbag, will play a greater and greater role on automobile.
(3) systematization：Automobile, road, people are included into a system to analyze and research, makes three mutually coordinated, reaches each
From the best match of performance, realize between Characteristics of drivers' behavior, vehicle mechanical characteristic and road equipment and traffic law most
Excellent coordination, pursues the optimum efficiency of system entirety.
(4) crewization：The passive security technology of personnel's injury is strongly saved or slowed down in accident generation moment, absolutely mostly
Number is the design concept based on protection passenger, for example, safety belt, air bag and can energy absorbing steering cloumn etc..From now on, automobile
Safe practice just develops towards the crewization direction for taking into account personnel safety outside in-car, car.
Gas pedal is also known as accelerator pedal.It is a part for motor vehicle fuel supply system.By controlling its tread-on quantity, to control
Engine air throttle aperture, controls air inflow, computer control oil mass, so as to control the rotating speed of engine.
Mis-accelerator pressing is on the one hand bad to engine, and meeting acceleration motor is lost, on the other hand, in some scenarios,
Mis-accelerator pressing in the case that for example underground garage turning needs touch on the brake under automobile, can cause injury to personnel, serious or even meeting
Cause the situation of personnel death.
Existing automobile is generally not provided with preventing the self-stopping device of mis-accelerator pressing.
