Technical field
The present invention relates to a kind of motorcar electric steering hardware and control method thereof, especially relate to a kind of automobile steering roller electric powered steering transmission control device and control method thereof.
Background technology
Current, automobile control wheel steering is the rotation that direction of passage dish, relevant steerage gear and actuating unit come the Control of Automobile wheel flutter jointly, thereby realizes turning to of automobile, and Here it is automobile is the most basic turns to function.
There is following technological deficiency in the mode of existing automobile control wheel steering:
(1) existing automobile steering roller turns to and is not that the direction of passage dish directly acts on the automobile steering roller; In fact the direction of passage dish directly acts on Steering gear; Directly acting on through Steering gear changes on the commutator again, realizes that finally deflector changes the angle of wheel flutter.Though this mode through the mechanical steering stack can be regulated wheel flutter, can produce the deviation that turns to of wheel flutter, can have influence on the reliability of driving safety when serious.
(2) in addition; Be connected through Steering gear between conventional direction dish and the deflector; Owing to there is long distance between bearing circle and the deflector; Thereby need the tween drive shaft setting of Steering gear is longer, so just reduced car load collision Steering gear crumple space length, reduced chaufeur driving safety level.
Summary of the invention
The present invention has designed a kind of automobile steering roller electric powered steering transmission control device and control method thereof; The technical matters of its solution is: (1) can produce the deviation that turns to of wheel flutter though existing automobile control wheel steering is can regulate wheel flutter through the mode of mechanical steering stack; (2) existing automobile control wheel steering need be longer with the tween drive shaft setting of Steering gear, reduced car load collision Steering gear crumple space length, reduced chaufeur driving safety level.
In order to solve the technical matters of above-mentioned existence, the present invention has adopted following scheme:
A kind of automobile steering roller electric powered steering transmission control device; Comprise bearing circle (1), Steering gear, rack and pinion steering gear (7), wheel flutter (6); Angular transducer (3), control module (9) and steer motor (4); Said Steering gear is divided into two sections independent sectors: upper end Steering gear (2) and lower end Steering gear (5), said upper end Steering gear (2) are connected between bearing circle (1) and the angular transducer (3); Said lower end Steering gear (5) is connected between steer motor (4) and the rack and pinion steering gear (7); The mouth of control module (9) and input end carry out the signal transmission with said angular transducer (3) and said steer motor (4) respectively, and said rack and pinion steering gear (7) is controlled correctly turning to of wheel flutter (6).
Further, be connected through CAN bus (9) between said angular transducer (3) and the said control module (9).
Further, connect through rigid line between said steer motor (4) and the said control module (9).
Further, said upper end Steering gear (2) is identical with said lower end Steering gear (5) rotational angle.
A kind of control method of automobile steering roller electric powered steering transmission control device may further comprise the steps: said angular transducer (3) is gathered bearing circle (1) steering angle value in real time and is delivered to control module (9); Said control module (9) calculates cooresponding steer motor (4) rotational angle value and steer motor (4) is sent the relevant work instruction according to bearing circle (1) steering angle value; Said steer motor (4) is according to the work of said steer motor (4) rotational angle value and act on rack and pinion steering gear (7) through lower end Steering gear (5); Said rack and pinion steering gear (7) is regulated the steering angle of wheel flutter (6).
Further, said bearing circle (1) steering angle is identical with said steer motor (4) rotational angle value.
This automobile steering roller electric powered steering transmission control device and control method thereof are compared with the mode that orthodox car control wheel changes, and have following beneficial effect:
(1) the present invention is owing to control steer motor rotational angle value and wheel steering angle value through the wheel steering angle value of steering angle sensor collection; Avoid traditional mechanical to turn to the deviation of stack generation; Make the wheel steering angle more accurate, drive safety and reliability.
(2) the present invention is because the wheel of vehicle steering angle is to confirm and realization through control module; Compare traditional mechanical and turn to the scantling length of having saved the steering column tween drive shaft; So just increase car load collision steering column crumple space length, make chaufeur safer.
