Passive non-key control system and control method thereof

Abstract

The invention relates to the technical field of automotive body control and safety control, in particular to a technology for initiating passive keyless entry and amp. A passive keyless control system provided by the invention comprises portable communication equipment and a vehicle control unit arranged inside a vehicle. The passive keyless control system further comprises a system for protecting an electronic chip in an engine against theft. The system for protecting the electronic chip in the engine against theft comprises an anti-theft authentication module which is arranged in the portable communication equipment and used for receiving and transmitting authentication information, and an anti-theft controller which is arranged in the vehicle and connected with an engine control system; and the anti-theft controller and the anti-theft authentication module authenticate an identity by encrypted communication, and control the engine control system on the basis of results of authentication. In an improved technical scheme, if the portable communication equipment enters a preset range, a door lock is opened automatically after a signal is authenticated. An anti-robbery control steps is added in an improvement over the improved technical scheme, so that after the engine is started, the engine brakes automatically as the portable communication equipment exits the preset range.

Description

technical field [0001] The invention relates to the technical fields of automobile body control and safety control, in particular to a keyless passive entry technology. Background technique [0002] Existing car keyless entry mainly adopts RKE (Remote Keyless Entry remote keyless entry system) technology. RKE technology has been used in the automotive field for many years and is still a mainstream product in car anti-theft and entry systems. The basic principle of RKE is that the key uses the rolling code technology (to prevent signal duplication), and the key information is encrypted and sent to the controller on the car through high-frequency (315MHz / 433MHz) to realize remote locking, unlocking, car search and other functions. For example, an improved RKE system is disclosed in the publication specification of the Chinese invention patent application with the publication number CN101262532A. The RKE system has at least two optional communication channels, but whether it i...

Problems solved by technology

For example, an improved RKE system is disclosed in the publication specification of the Chinese invention patent application with the publication number CN101262532A. The RKE system has at least two optional communication channels, but whether it is a traditional RKE system or an improved RKE system , can not start the car engine without a key, which brings inconvenience to the user; at the same time, the current RKE system also needs to manually press the button on the RKE remote control, and the car will perform corresponding operations under the control of the RKE system, and its use is also difficult. It is not convenient enough, especially when the owner has other items in his hands, it is more difficult to free up his hands to open the door; the existing RKE system is not perfect in anti-theft measures
