Change, the Emergency avoidance that driver is trusted is avoided colliding and be turned on one's side.
The technical solution adopted by the present invention to solve the technical problems is: using it is a kind of based on auto vendor it is preset with it is fast
Matched steering wheel safe corner data are spent, change the hard-over range of steering wheel, including anti-rollover evaluation and test control list in real time
Member with steering wheel angle sensor, vehicle speed sensor, car body obliqueness sensor, steering wheel vibration device, the control of steering wheel angle displacement device,
System switching connection.Wherein, the various speed of storage factory pre-sets are pacified with corresponding steering wheel in anti-rollover evaluation and test control unit
Full corner limit data, and steering wheel angle range can be primarily determined according to vehicle speed sensor, believed by car body obliqueness sensor
Number understand road surface angle, correct inherently safe angle data, and by safe corner data and steering wheel angle sensor signal ratio
Compared with giving steering wheel vibration device and issue crescendo signal, warning driver carefully drives when steering wheel angle is close to security boundary
It sails, once steering wheel angle reaches safety turning arm of angle circle, anti-rollover evaluates and tests control unit immediately to the control of steering wheel angle displacement device
Control signal is issued, steering wheel angle range controller takes the mode for increasing resistance unidirectionally to hinder steering wheel over range immediately
Rotational action.The control of steering wheel angle displacement device hinders the rotation of steering wheel over range and non-fully obstructs, and only surpasses model to steering wheel
It encloses rotation and increases an apparent resistance, driver is allowed to appreciate immediately that the accurate location of safety turning radial limits, still, if
Driver thinks that the consequence hit is more more serious than overturning, and driver, which can choose, ignores this warning, continues reinforcing rotation
Steering wheel.System switching is for enabling and closing anti-rollover system, it is therefore intended that interferes normally when anti-rollover system breaks down
When driving, the influence of anti-rollover system can be stopped.When work, system switching is opened, anti-rollover evaluates and tests control unit not disconnecting
The signal from vehicle speed sensor is received, is passed according to the preset steering wheel safe corner data of speed selection, then by car body obliqueness
The signal correction data of sensor, when the signal display direction disk corner of steering wheel angle sensor is close to safe corner boundary,
With the raising of the degree of approach, anti-rollover evaluation and test control unit gives steering wheel vibration device and issues crescendo signal, and steering wheel is increased
Vibratory alarm driver carries out prepare at heart in advance close to side to overturn angular limit, avoids surprisingly crossing the border, once steering wheel angle arrives
Up to safety turning arm of angle circle, anti-rollover evaluates and tests control unit and issues control signal, steering wheel to the control of steering wheel angle displacement device immediately
Rotary corner controller is given and is responded in a manner of obviously increasing steering wheel one-directional rotation resistance immediately, and the control of steering wheel angle displacement device can be with
In conjunction with power steering system, one direction power-assisted intensity is reduced in real time, the control of steering wheel angle range is realized, in no power
On the automobile of steering system, directly increases by two electromagnetic force ratchet one-way braking mechanisms in shaft in the steering system, utilize spine
The characteristics of single load bearing of wheel, realizes that positive and negative two one directions increase the control of resistance.If driver thinks to hit than overturning more
To be serious, steering wheel rotation can be reinforced by force, to mitigate damage sequence.
The invention has the advantages that changing direction in real time using the preset safe speed of auto vendor and angle data
The hard-over range of disk does not depend on the technology and experience of driver, accomplishes to avoid rollover and avoids collision to greatest extent
Harm.
Detailed description of the invention
