Abstract
The utility model provides an automobile tire burst proof control system based on steering, and relates to automobile security control devices. The automobile tire burst proof control system based on steering comprises a steering wheel, a steering wheel angle sensor, a steering shaft, a universal joint shaft, a steering pinion, a transmission gear, an electronic control clutch, a steering motor, a tire burst control Electronic Control Unit (ECU), an automobile speed sensor, an automobile body suspension roll sensor, an indicator light and horn alerter, a steering wheel, a wireless tire pressure sensor, a steering tie rod, a steering rack and a tie rod displacement sensor. When tire burst occurs, the automobile tire burst proof control system based on steering starts a tire burst warning device, sends out tire burst warning information through the indicator light and horn alerter, switches on the steering motor through the electronic control clutch, enables the steering motor to control a steering system of an automobile to enter tire burst control, and prevents automobile tires from being out of control, which can cause off tracking, when tire burst occurs.
Description
Technical field
The utility model relates to safety control device for automobile, particularly a kind of automobile tire burst prevention control system based on turning to.
Background technology
The easy sideslip out of control of direction caused casualties and the property damage accident when motor tire was blown out suddenly, industry has been done deep research to the automobile tire burst prevention control technology for this reason, present automobile tire burst prevention control technology complex structure, and cost is high, operating efficiency ground needs the shortcomings such as auxiliary device.A kind of automobile tire burst prevention control system based on turning to of this application, its core is to utilize steering swivel system that road holding is controlled after occuring when blowing out, prevent Vehicle Driving Wandering or rollover, and have advantages of that cost is low, simple in structure, reliability is strong.The key distinction is in utilizing brake equipment to carry out runflat control.
The prior art that approaches with present technique has two classes, one class is to blow out to brake control after occuring, one class is braking and turns to simultaneously control, wherein representative have: (1) a kind of flat tire braking system based on antiblock device, the patent No. is 200820162261.3, the core of this technology is to utilize tyre pressure sensor to detect the pressure information of motor tire, if detecting certain takes turns Somatic Embryogenesis and blows out, then at once signal of tyre burst is transferred to central processing unit, central processing unit can be controlled automatic brake mechanism and carry out braking deceleration and brake.The shortcoming of this technology is that the side direction adhesion value of automobile in braking procedure is with variation, road holding variation namely, therefore utilize brake system to the stability of direction control limited in one's ability, when the speed of a motor vehicle than very fast, when weight is larger, effect will be restricted; (2) vehicle tyre-bursting security control method and system, the patent No.: 200810119655.5, the core of this technology be utilize brake, turns to, closed loop control systems of formation such as TPMS, CAN system, concrete control method: after TPMS detects signal of tyre burst, arrive each system by the CAN bus transfer, brake system is in time adjusted left and right sides brakig force distribution, and steering swivel system in time is reversed power-assisted.The type advantage of system is that control is accurate, need not to increase new hardware.Shortcoming is that this system is very high to car load requirement configuration, need to configure simultaneously ABS or ESP (body electronics stabilization system), EPS (automatically controlled steering boost system), and TPMS, CAN buses etc. are because cost is higher.Because need the simultaneously mating reaction of several systems, technical risk is large, and turns to control in braking, it controls weak effect, mainly be that the lateral adhesion coefficient of automobile sharply diminishes owing to braking later on, enough steering control effort can not be provided, the direction unstability easily occurs in automobile.
Current runflat control technology or cost is too high as can be known by above analysis, or is exactly that poor reliability or technology are not mature enough, and be that apply in market and few.
The utility model content
The purpose of this utility model be for overcome and solve existing automobile since do not have perfect blow out anti-deflection device and when motor tire occurs blowing out suddenly easy sideslip out of control cause casualties, shortcoming and the problem of property damage accident; a kind of automobile tire burst prevention control system based on turning to is provided; when automobile travels with middle and high speed and occurs blowing out suddenly; can reliably, effectively prevent Vehicle Driving Wandering, automatically keep automobile on original travel direction; the protection ride safety of automobile prevents that personal casualty and property damage accident from occuring.
The technical solution adopted in the utility model is to achieve the above object of the invention: a kind of automobile tire burst prevention control system based on turning to, and this system comprises vehicle steering (1), rotary angle transmitter (2), steering shaft (3), propeller-shaft (4), turn to miniature gears (5), transmission gear (6), electric control clutch (7), steer motor (8), control ECU (9) blows out, car speed sensor (10), body roll sensor (11), indicator lamp and loudspeaker warner (12), wheel flutter (13), radio tire pressure sensor (14), tierod (15), steering rack (16), intermediate rod displacement pickup (17).
The technical solution of the utility model is: described vehicle steering (1) is connected with steering shaft (3), rotary angle transmitter (2) is installed on the steering shaft (3), steering shaft (3) is connected with propeller-shaft (4), propeller-shaft (4) is connected with turning to miniature gears (5), turn to miniature gears (5) and transmission gear (6) engagement, simultaneously lower end and steering rack (16) engagement, transmission gear (6) is connected with electric control clutch (7), electric control clutch (7) is connected with steer motor (8), steering rack (16) is connected with tierod (15), and tierod (15) is connected with wheel flutter (13); Rotary angle transmitter (2), car speed sensor (10), body roll sensor (11), intermediate rod displacement pickup (17) and electric control clutch (7), steer motor (8), indicator lamp are connected 12 with loudspeaker warner) control ECU (9) is connected by wire with blowing out; Radio tire pressure sensor (14) and the control ECU (9) that blows out are by wireless connections.
Adopt a kind of automobile tire burst prevention control system based on turning to of the utility model to have following beneficial effect:
1. a kind of automobile tire burst prevention control system based on turning to of the utility model adopts initiatively runflat technology, when blowing out, start immediately electric power steering ACTIVE CONTROL motor turning to correct owing to blowing out caused vehicle yaw, and reported to the police by tire burst alarming device, because automobile flat tire control ECU turns to control by carried out by steer motor after the value that gathers the radio tire pressure sensor at once, the required reaction time is short, so the utility model personal casualty and the property damage that can effectively avoid automobile flat tire to cause.
2. a kind of automobile tire burst prevention control system based on turning to of the utility model is to utilize the control electric power steering to realize the runflat control of automobile, with utilize the brake system runflat and compare, owing to not changing wheel to the sliding ratio on ground, therefore lateral adhesion coefficient is constant, and then in control process the less generation direction of automobile unstability, so its control better effects if.
