Keyless control system of automobile

Abstract

The invention relates to a keyless control system of an automobile. The keyless control system is characterized by comprising an automobile intelligent key and a PEPS controller, wherein the PEPS controller is connected with an automobile body controller of the automobile and a door lock central control system of the automobile; the automobile intelligent key comprises a first processing module, a first close-range wireless communication module and a first movement sensing module; and the PEPS controller comprises a second processing module, a second close-range wireless communication module and a first CAN communication module. According to the keyless control system disclosed by the invention, the information of command movements of an owner of the automobile is detected by the first movement sensing module, and the movement commands of the owner of the automobile is checked, so that the risk that the electromagnetic signal of the PEPS controller is intercepted and transferred so that the electromagnetic signal is possibly stolen can be effectively avoided; and in addition, the first movement sensing module is arranged, so that the capacity expansion of the automobile intelligent key can be greatly extended, and more intelligent applications can be realized.

Description

technical field [0001] The invention relates to a car keyless control system and relates to the technical field of smart cars. Background technique [0002] With the continuous advancement of automobile electronic control technology and the continuous popularization of the concept of intelligent life, modern automobiles are becoming more and more intelligent, and the use of intelligent hardware is becoming more and more extensive. Keyless entry and start (Passive Entry and Passive start, PEPS) systems are increasingly used in various models, and smart bracelets have also become an important tool for many people's life records. The PEPS system can complete the automatic opening and locking of the car door according to the smart key carried by the car owner. After entering the car, the car owner only needs to press the start button to complete the car start action, thus greatly reducing the time required for unlocking the door and starting the car in traditional cars. step an...

Problems solved by technology

Although these two methods can reduce the steps and time of unlocking the door and starting the vehicle in traditional cars to a certain extent, and improve the comfort of using the car, there are serious security loopholes, that is, they may be targeted by criminals through electromagnetic equipment. The electromagnetic signal is intercepted, relayed and propagated, which causes the PEPS controller to mistakenly believe that the smart key is in the effective range, and sends an unlock signal to the central control system, resulting in the risk of the car being hacked
