(8) ESCL replys lock operating state and power-off License Info;
(9) PEPS controller disconnects power supply to ESCL;
(10) PEPS controller disconnects ground connection by CAN notice BCM to ESCL.
Further, keyless systems controller PKE only just powers on to it when electronic steering column lock ESCL needs action, during ESCL locks motor action, forbid power-off, and arranging the ESCL action time-out time that powers on is 1 second.
Beneficial effect of the present invention is: electronic steering column lock control method of the present invention is suitable for various automotive field, the method is simple, and by the method, vehicle electronics lock for steering column is controlled to have very high reliability and safety, the anti-theft feature of vehicle can be realized well.
Accompanying drawing explanation
In order to make object of the present invention, technical scheme and beneficial effect clearly, the invention provides following accompanying drawing and being described:
Fig. 1 is the control block diagram of electronic steering column lock control method of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
Fig. 1 is the control block diagram of electronic steering column lock control method of the present invention, as shown in the figure, electronic steering column lock control method of the present invention realizes by entering startup system control device PEPS, car body controller BCM and electronic steering column lock ESCL without key, in the present embodiment, adopt respectively and enter without key the both positive and negative polarity that startup system control device PEPS and car body controller BCM controls electronic steering column lock ESCL power supply, can prevent like this because single controller fault causes electronic steering column lock maloperation.
Enter startup system control device PEPS without key in the present embodiment and there are main and auxiliary two MCU, adopt main and auxiliary two MCU independently to control electronic steering column lock ESCL to power, thus prevent because single MCU fault causes the failure of electronic steering column lock action executing.
Employing redundant signal transmission mechanism, uses LIN bus and the dead bolt status signal contrast of physical hardwired to electronic steering column lock ESCL to detect, improves the reliability of lock for steering column.
In the present embodiment, without key enter startup system control device PEPS control electronic steering column lock perform solution, block action time, send fixed code by LIN bus to ESCL and carry out certification, electronic steering column lock ESCL by the fixed code of reception compared with the fixed code of self preserving, consistent then authentication success, ESCL just allows execution to unblock action.So will perform corresponding action by control ESCL, ESCL must have identical fixed code with PEPS controller, and therefore first PEPS and ESCL must perform coupling, preserves, the steps include: in the fixed code write ESCL in PEPS
(1) diagnostic equipment sends in fixed code fixcode and security code to PEPS and preserves;
(2) diagnostic equipment sends coupling order to PEPS controller;
