Abstract
The utility model discloses an electronic steering column lock control system, which comprises an electronic steering column lock column lock and an intelligent entry controller and is characterized by further comprising an automobile controller for acquiring automobile state information, the signal output end of the automobile body controller is connected with the signal input end of an electronic steering column lock, and a communication port of the intelligent entry controller is connected with a communication port of the electronic steering column lock. The electronic steering column lock control system realizes dual judgment of locking and unloading states of the electronic steering column lock by arranging the intelligent entry controller and an automobile controller which are connected with the electronic steering column lock, thereby enhancing the reliability of the electronic steering column lock control system and improving the reliability of a keyless entry system.
Description
Technical field
The utility model relates to the auto parts and components field, refers to a kind of electronic steering column lock control system particularly.
Background technology
Existing vehicle does not have key intelligent and gets into system; Connect and compose by electronic steering column lock (being called for short ESCL) and intelligent control of access device (being called for short PEPS); When the car load electric source modes when OFF changes; This control system is judged unlocking condition through intelligent control of access device, thereby realizes the release of electronic steering column lock.Can find out by said structure; Whether what existing vehicle did not have that key intelligent gets into that system only collects according to intelligent control of access device (being called for short PEPS) is that the information of legal key judges whether Steering gear is carried out release or locks; This system is judging whether that Steering gear is carried out release or when locking; Ignored and gathered other status information of automobile, like shifting state, the speed of a motor vehicle, system power supply state, brought potential safety hazard for like this traffic safety of chaufeur.
Summary of the invention
The purpose of the utility model is exactly that a kind of electronic steering column lock control system that can guarantee the traffic safety of chaufeur will be provided.
For realizing this purpose; The utility model institute design-calculated electronic steering column lock control system; It comprises electronic steering column lock and intelligent control of access device, and it also comprises the car body controller (BCM, Body Control Module) that is used to gather vehicle condition information; The signal output part of said car body controller connects the signal input part of electronic steering column lock, and the COM1 of said intelligent control of access device connects the COM1 of electronic steering column lock.
The COM1 of said intelligent control of access device is through the COM1 of the total wire joint electronic steering column lock of LIN/K.
The utility model is through being provided with and electronic steering column lock bonded assembly intelligence control of access device and car body controller, realized the electronic steering column lock dual judgement with released state of unblanking, thereby strengthened the reliability of electronic steering column lock control system.And improved the reliability of keyless access system.
Description of drawings
Fig. 1 is the structured flowchart of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify:
Electronic steering column lock control system shown in Fig. 1; It comprises electronic steering column lock, intelligent control of access device and is used to gather the car body controller of vehicle condition information; The signal output part of car body controller connects the signal input part of electronic steering column lock, and the COM1 of intelligent control of access device connects the COM1 of electronic steering column lock.
In the technique scheme, the COM1 of said intelligent control of access device is through the COM1 of the total wire joint electronic steering column lock of LIN/K.Electronic steering column lock feeds back the state of current lock through the LIN/K bus, and intelligent control of access device sends the CAN bus message of separating/lock successfully (failure) after receiving the status signal of lock.And can realize diagnosis function.
In the technique scheme, car body controller BCM is the existing module that is equipped with in present most automobiles, and this module can be carried out light control, windscreen wiper control, and signals such as shifting state signal that can collection vehicle, speed information, system power supply state.
During the utility model work: thus electronic steering column lock can pin or the bearing circle of the lock for steering column Control of Automobile of release automobile is locked; Intelligence control of access device judges through its in-to-in ECU whether key is legal key; Simultaneously; Car body controller is passed to the inside ECU of electronic steering column lock with the various real-time parameters (like shifting state, the speed of a motor vehicle, system power supply state) of automobile, and electronic steering column lock obtains combining key behind shifting state, the speed of a motor vehicle, the system power supply status signal, and whether legal signal judges whether to carry out locked to the bearing circle of Control of Automobile.
It is above-mentioned that to judge whether that automobile steering wheel is carried out locked basis for estimation following:
The unlocking condition of the utility model is: 1) the system power supply pattern is at " OFF "; 2) electronic steering column lock ESCL is current is locking state; The ECU of intelligence control of access device PEPS finds legal key in car.The trigger condition of this moment is: system power supply handoff request (switching to ACC or CRANK from OFF).At this moment, car body controller is passed to electronic steering column lock with the system power supply pattern at the signal of " OFF ", and intelligent control of access device is passed to electronic steering column lock with the signal of legal key, and electronic steering column lock obtains release automobile steering wheel behind the above-mentioned signal.
The condition of locking of the utility model is: 1) speed of a motor vehicle is 0km/h; 2) electronic steering column lock ESCL is current is released state; 3) the system power supply pattern is at " OFF "; 4) the change speed gear box gear is in P retaining (AT) or neutral (MT).The trigger condition of this moment is: driver-side door contact interrupter state changes.At this moment; Car body controller is the signal of 0km/h with the speed of a motor vehicle; The system power supply pattern is at the signal of " OFF ", and the change speed gear box gear is passed to electronic steering column lock at the signal of P retaining (AT) or neutral (MT), if electronic steering column lock is released state at this moment; Then electronic steering column lock is controlled locked Steering gear, thus locked automobile steering wheel.
Above-mentioned unlocking condition and the condition of locking have improved the reliability of keyless access system.Guaranteed the safety of chaufeur driving license automobile.
The content that this specification sheets is not done to describe in detail belongs to this area professional and technical personnel's known prior art.
