Abstract
The invention discloses a control system for preventing rollover of a vehicle, which comprises a micro-control unit, a vehicle sensor, a display device and a brake actuator of an electronic mechanical brake system, wherein the vehicle sensor is connected with a signal input end of the micro-control unit, and the display device and the brake actuator are respectively connected with a signal output end of the micro-control unit. According to the control system provided by the invention, the running parameters of the vehicle are collected by the vehicle sensor, the running parameters are transmitted to the micro-control unit for treating and analyzing, and then the rollover warning time is sent by the micro-control unit according to the analysis so as to remind a driver of realizing manual control, and meanwhile, the brake actuator of the electronic mechanical brake system is controlled to realize automatic brake, so as to effectively prevent the vehicle from rollover and excellently ensure the safety of the driver. The control system provided by the invention has the advantages of simple structure, convenience in manufacturing, high response speed and stable structural property.
Description
Technical field
The present invention relates to a kind of automobile automobile safety protector field, specifically is a kind of car for guarding against side turned over control system.
Background technology
Along with science and technology development, the increasing entering of automobile people life.But people are also more and more high to the requirement of automobile, to traveling comfort, safety, intelligent the having higher requirement of automobile.The progressive electronics of science and technology and the emergence of the communications field simultaneously, the active safety performance of automobile is greatly improved.Automobile active safety will be to reduce the important part of traffic accident, and at present domestic a lot of car production producer has recognized this point, drops into the research and development of this gate technique one after another.A lot of car production producers have adopted multinomial active or passive security measure, have improved the safety of automobile to a great extent.Yet, can cause the vehicle side turning traffic accident of mortal injury usually as one of serious problems of automotive safety, but do not receive more concern up to now.The statistics of U.S. highway traffic safety administration NHTSA shows: in all traffic accidents, the harm that the vehicle side turning accident causes is only second to the harm that occupies primary automobile collision accident generation; Though vehicle rollover traffic accident incidence is hanged down 3% in all accidents of vehicle that only account for, it can cause and surpass 33% mortality, and in the loss that all accidents cause, its proportion can be up to 60% simultaneously.Die every year in the vehicle side turning traffic accident up to 1000 people, wherein just have 75% possibility that causes death, even be safety strap when accident takes place.In recent years, the increasing major traffic accidents of China are produced by vehicle side turning and cause very serious harm in personal casualty and economic aspect.
At present comparatively general and anti-rollover method that can effectively improve vehicle side turning stability comprises: active lateral stabiliser technology, active steering be technological, initiatively brake technology, differential braking control technology etc.Above-mentioned various methodologies all some problems can occur when the anti-rolling practical implementation of the actual active of automobile.Can improve the rollover threshold value and suppress vehicle rollover even for example be used for the active lateral stabiliser of car for guarding against side turned over control, but it can't satisfy the response rapidity requirement of anti-rollover; Because the variation of wheel flutter deflection angle causes the not enough problem of Vehicular turn easily, change the intention of going of chaufeur through active steering technology anti-rollover, influenced the operating characteristic of vehicle.
Summary of the invention
The technical matters that the present invention will solve provides a kind of car for guarding against side turned over control system, adopts the braking of micro-control unit controls electromechanical braking system brake actuator, can prevent effectively that the situation of vehicle side turning from occurring.
Technical scheme of the present invention is:
A kind of car for guarding against side turned over control system includes micro-control unit, with micro-control unit signal input part bonded assembly automobile sensor, and respectively with micro-control unit signal output part bonded assembly read out instrument and electromechanical braking system brake actuator.
Described automobile sensor is connected through the signal input part of first A/D converter and micro-control unit; Described electromechanical braking system brake actuator is connected through the signal output part of second A/D converter and micro-control unit.
Described electromechanical braking system brake actuator is connected with automobile sensor.
Advantage of the present invention:
The present invention is employed in widely used electromechanical braking system (EMB) Control of Automobile rollover in the full electric brake control of aircraft.The electric mechanical braking technology is used aboard and is reached its maturity, and is in the research and development period that transforms to automotive field at present.EMB is replaced original conduit under fluid pressure by electric wire, adopt the electrical equipment DC machine to produce moment and make mechanics work, compares it with original fluid control and is swift in response and can each wheel be separated control, partly be connected with automobile MCU and be more prone to.Therefore, the present invention adopts the brake actuator of EMB as the anti-rollover control system, need not to increase additional hardware and just can satisfy the control requirement.
The present invention gathers the operational factor of automobile through automobile sensor; Be transferred to micro-control unit then and carry out Treatment Analysis; Micro-control unit reminds chaufeur to realize manually control according to sending the rollover pre-warning time after analyzing then; Also may command electromechanical braking system brake actuator is realized autobrake simultaneously, can effectively prevent vehicle side turning, fine guarantee driver safety; And the present invention is simple in structure, easy to make, and speed of response is fast, and structural behaviour is stable.
Description of drawings
Fig. 1 is a functional block diagram of the present invention.
The specific embodiment
A kind of car for guarding against side turned over control system; Include micro-control unit 1; Through first A/D converter 3 and micro-control unit 1 signal input part bonded assembly automobile sensor 2; With the direct coupled read out instrument 4 of micro-control unit 1 signal output part, through second A/D converter 6 and micro-control unit 1 signal output part bonded assembly electromechanical braking system brake actuator 5; And electromechanical braking system brake actuator 5 is connected with automobile sensor 1.
Use principle of the present invention:
Automobile sensor 2 is converted into electric signal with the vehicle operational mode parameter; This electric signal is input in the micro-control unit 1 through first A/D converter 3 then; Micro-control unit 1 draws rollover pre-warning time value through the data that collect are handled; Micro-control unit 1 compares this pre-warning time value and reference rollover pre-warning time value simultaneously; If current rollover pre-warning time value is greater than reference rollover pre-warning time value; Micro-control unit 1 transfers to this rollover pre-warning time value in the read out instrument 4 and shows; Make chaufeur realize braking according to this time data manual operation electromechanical braking system brake actuator 5, less than reference rollover pre-warning time value, micro-control unit 1 is directly controlled electromechanical braking system brake actuators 5 realization autobrake through second A/D converter, 6 output control signals as if current rollover pre-warning time value; In the process of electromechanical braking system brake actuator 5 operations, 2 of automobile sensors are gathered related data in real time.
