Central locking system for vehicle - has antitheft protection coupled to lock action to provide fail-safe protection

摘要

The separate locks are fitted with a separate control as well as a central control to operate all the locks. The anti-theft protection secures each lock and operates at the same time, providing failsafe protection. A controller (ST) has a first switching system (T1,R1) which operates on the lock mechanisms, while a second switching system (T2,R2) operates on the blocking mechanisms of the anti-theft protection. - A security fuse (S) is in line with the control systems and the locking systems and the two switching systems are separated by a time delay circuit. A third switching system operates the release of the locks.
