Description
Technical field
The utility model relates to the antitheft field of automobile electronic steering system, particularly a kind of technology of detected electrons lock for steering column dead bolt.
Background technology
Current electronic lock for steering column detects latch bolt position and mainly contains: use double microswitch redundancy determination dead bolt final position or single micro-switch and pulse totalizer to judge dead bolt movement travel.
The first control method is relatively single, can only, by the position of the condition adjudgement dead bolt of micro-switch, be easy to occur that position judgment does not go out, and electronic steering column lock status is easy to occur non-released state of locking.
Although second method improves the reliability that dead bolt detects, because the parts participating in controlling are many, control system relative complex, particularly pulse totalizer require that motor movement is slow, cause the whole electronic steering column lock lock and unlock time elongated.
Utility model content
The utility model detects the problem existing for the technology of latch bolt position for existing detected electrons lock for steering column, and provides a kind of control system of detected electrons lock for steering column dead bolt.The degree of detection of this control system modularization, high reliability, and high-responsivity.
In order to achieve the above object, the utility model adopts following technical scheme:
A control system for detected electrons lock for steering column dead bolt, described control system comprises:
Controller unit, described controller unit is by the communication of Vehicle Body Bus and outside vehicle body control unit, and control linkage motor control unit;
Motor control unit, described motor control unit drives and connects motor, and described motor is driven by mechanical transmission mechanism and connects lock for steering column dead bolt;
Dead bolt detecting unit, described dead bolt detecting unit coordinates with mechanical transmission mechanism and connects, and connection control device unit.
In the preferred embodiment of control system, described dead bolt detecting unit comprises the double microswitch of Hall element and redundancy setting.
Further, described Vehicle Body Bus is CAN/LIN bus.
The utility model adopts the control of Hall element and double microswitch cooperation detection electronic steering column lock latch bolt position, and it achieves the Redundant Control detecting logic, and the safety and reliability that the dead bolt state-detection of whole lock for steering column is judged is improved.
Meanwhile, the utility model solves the limitation that current lock for steering column control system judges latch bolt position, improves the reliability of whole electronic steering column lock system, makes electronic steering column lock control safer, and modularization.
Accompanying drawing explanation
The utility model is further illustrated below in conjunction with the drawings and specific embodiments.
Fig. 1 is systematic schematic diagram of the present utility model.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
See Fig. 1, the control system of the detected electrons lock for steering column dead bolt that the utility model shown in it provides.This control system mainly comprises pcb board 10 and is integrated in the electronic steering column lock control unit (not marking in figure) on pcb board 10.This electronic steering column lock control unit forms primarily of controller unit 20, motor control unit 30 and dead bolt detecting unit 60.
Controller unit 20 is responsible for, by Vehicle Body Bus (CAN/LIN etc.) and outside vehicle body control unit communication, obtaining real-time vehicle body information state, and drive motor control unit 30, realize controlling electronic steering column lock lock and unlock according to control logic.This controller unit 20 specifically can be formed by corresponding hardware controls chip.
Motor control unit 30 is responsible for whole electronic steering column lock control system and is powered, and controls dead bolt sense of motion.Concrete, motor control unit 30 be corresponding circuit for controlling motor, drived control motor 70, and motor 70 is undertaken unlocking by the dead bolt 50 that mechanical transmission mechanism 40 drives electronic steering column to lock, action of locking, thus the lock solution lock control of realization to dead bolt 50.
Dead bolt detecting unit 60 is controlled by controller unit 20, and match with mechanical transmission mechanism 40 and connect, it is by detecting the state of kinematic motion of mechanical transmission mechanism 40 to obtain the position of dead bolt, and the information detected is reached controller unit 20, controller unit 20, according to the position of the dead bolt detected, calculates that electronic steering column lock failure-free is locked, released state.
Concrete, dead bolt detecting unit 60 mainly comprises Hall element 61 and double microswitch (being again redundancy micro-switch) 62, and both test sides coordinate with mechanical transmission unit 40 respectively and connect, and mouth connection control device unit 20 respectively.Respectively real-time detection is carried out to the state of kinematic motion of mechanical transmission mechanism 40 by Hall element 61 and double microswitch 62 like this.When the transmission of mechanical transmission mechanism 40 pairs of dead bolts 50, by the change signal of Hall element and the state of double microswitch.
The data that controller unit 20 is collected by detection double microswitch state and Hall element, judge whether dead bolt has moved and put in place, the released state thus acquisition electronic steering column lock failure-free is locked.
Thus, this control system operationally, is locked if controller unit 20 receives outside, when unlocking triggering, is first judged vehicle body state.
If meet unlocking motion of locking, controller unit 20 drive motor control unit 30, control motor 70 by motor control unit 30 to run, then motor 70 dead bolt 50 will be driven to carry out locking by mechanical transmission mechanism 40, unlocking movement, realize the control to dead bolt 50.
In driving process, in dead bolt detecting unit 60 double microswitch 62 dead bolt move to lock or released state time, state overturns, and detects acquisition in real time by controller unit 20.
Simultaneously in the whole motion process of dead bolt, Hall element signal intensity is also caught by controller unit 20.
The state variation of double microswitch of the comprehensive dead bolt detecting unit 60 of controller unit 20 and the change of Hall element signal, can judge the position of dead bolt 50 and the state of electronic steering column lock safely and reliably.
More than show and describe groundwork of the present utility model, principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
