Description

technical field [0001] The present invention relates to a vehicle remote control anti-theft learning system, in particular to a remote control with a code learning function (code learning) and a function of clearing old codes (code wash), so that when a new code is implanted, the new code is confirmed All old passwords will be cleared only after they are correct. Background technique [0002] The general anti-theft device is designed with a first-in-first-out (FIFO) configuration for setting password circuit programs, that is to say, when setting passwords, each password can be stored in the memory according to the order of learning codes, so that a car Can accept multiple remote controls at the same time. [0003] After using the above method, it is found that there are many disadvantages. For example, when the car owner hands over the car to other people (such as: parking personnel, car repair shop), if he is coveted by unscrupulous people, he will be able to easily pass ...

[0003] After using the above method, it is found that there are many disadvantages. For example, when the car owner hands over the car to other people (such as: parking personnel, car repair shop), if he is coveted by unscrupulous people, he will be able to easily pass the car password. To join a group, the method is: make the anti-theft device enter the learning state, implant the password of the pre-stored remote control into the host, and the host will store the passwords in the memory in order according to the first-in-first-out (FIFO) method at this time In the body, at this time the host has been able to accept new illegal passwords, but it is difficult for the owner to find out

[0004] It can be seen that the above-mentioned commonly used articles still have many shortcomings, which are not really a good design, and need to be improved urgently.
