Abstract
The utility model discloses a device for controlling too frequent steering of a steering wheel. The device comprises a diverter locking device arranged on a coach, a relay, a front wheel velocity sensor and a longitudinal coach body velocity sensor and also comprises a single chip microcomputer. The diverter locking device, the relay and a D/A (digital/analog) converter are sequentially connected; and the D/A converter, the front wheel velocity sensor and the longitudinal coach body velocity sensor are connected with the single chip microcomputer. According to the utility model, the speed of a vehicle body and the speed of front wheels are obtained and are adopted as foundation for judgment; a maximum steering range of the steering wheel under the current speed of a coach is solved through the single chip microcomputer; then the single chip microcomputer controls the diverter locking device to work, so that the coach can safely avoid danger and suffer no rollover at the same time.
Description
Technical field
The utility model belongs to automobile technical field, the too much restraining device of wheel steering when being specifically related to a kind of automobile emergency hedging.
Background technology
When motorcoach was run at high speed, if people or car appear suddenly in the place ahead, chaufeur tended to take braking or beats direction toward anxious on one side, and movement interference appears in front-wheel and trailing wheel like this, and this moment, motorcoach received bigger transverse force, was prone to cause motorcoach rollover accident; And chaufeur is easy to turn on one's side as long as be interfered because the overstretched negative understeer that tends to is because the motorcoach vehicle body is high, very low in high speed under body operational stability at this moment in this case.And also there is not to suppress specially the too much device of motor turning in the prior art.
Summary of the invention
To the defective or the deficiency of prior art, the purpose of the utility model is to provide a kind of wheel steering too much restraining device, to avoid vehicle in the process of running at high speed, meets emergency situation and because of negative understeer rollover or other traffic accidents takes place.
For realizing above-mentioned technical assignment, the utility model is taked following technical solution:
The too much restraining device of a kind of wheel steering; Comprise steering-wheel lock locking apparatus, relay, front-wheel speed sensor and the vehicle body longitudinal velocity sensor installed on the passenger vehicle; It is characterized in that; Also comprise a micro controller system, said steering-wheel lock locking apparatus, relay are connected with D/A converter successively, and D/A converter, front-wheel speed sensor and vehicle body longitudinal velocity sensor are connected with micro controller system respectively.
The too much restraining device of the wheel steering of the utility model; Through obtaining vehicle body speed and front-wheel speed at that time; With the speed interference is basis for estimation; Calculate by micro controller system and to try to achieve the maximum steering handwheel deflection angle scope that allows under the speed of a motor vehicle at that time, by the work of Single-chip Controlling steering-wheel lock locking apparatus, the rollover accident can not take place when making motorcoach safety hedging afterwards.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify.
The specific embodiment
Referring to Fig. 1; Present embodiment provides the too much restraining device of a kind of wheel steering; Comprise steering-wheel lock locking apparatus, relay, D/A converter, micro controller system, vehicle body longitudinal velocity sensor, the front-wheel speed sensor installed on the passenger vehicle, on the steering-wheel lock locking apparatus, be connected with relay, relay links to each other with D/A converter; D/A converter is connected with micro controller system, and vehicle body longitudinal velocity sensor is connected with micro controller system respectively with the front-wheel speed sensor.
Obtain vehicle body longitudinal velocity v respectively by vehicle body longitudinal velocity sensor and front-wheel speed sensor
xWith the front-wheel speed v
1, and be transferred to micro controller system; Micro controller system is interfered Rule of judgment according to speed: if v
x＜1.5kv
1Cos δ
o, think that then current turning to belongs to safe condition; If v
x>=1.5kv
1Cos δ
o, think that then current turning to belongs to precarious position, wherein: v
xBe vehicle body longitudinal velocity, v
1Be front-wheel speed, k is factor of safety (getting 0.6～0.8), δ
oBe front wheel angle, calculate the safe condition of motorcoach at that time, if the chaufeur negative understeer; Micro controller system sends instruction; Is electric signal by D/A converter with this instruction transformation, and is delivered to relay, and relay switch closes; Deflector locking device control circuit is connected, and operating mechanism moves the bearing circle locking.
Claims (1)
