Description
Technical Field
The invention belongs to the technical field of automobile systems, and particularly relates to a legal key scanning method based on a Bluetooth key function.
Background
The keyless entry and starting PEPS system is an automobile electronic technology developed in recent years, a vehicle owner installing the PEPS system only needs to carry about without taking out a key, the operations of unlocking, locking, opening a trunk, starting the vehicle, automatically opening a vehicle window and the like can be completed, the vehicle owner can conveniently use the vehicle, the Bluetooth communication technology is combined with the PEPS system, the developed Bluetooth keyless entry and starting system is free from the trouble that the vehicle owner can use the vehicle only by carrying an electronic key, and the use experience of the vehicle owner is improved.
The connection mode of cell-phone and car is connected with the bluetooth, can avoid carrying legal mobile terminal at underground garage or the condition that can't operate in the place that the mobile signal is not good enough, and the user accessible replaces carrying traditional electronic key, unlocks and starts the vehicle, nevertheless the inside scanning key method of current PEPS module still has following drawback in the in-service use:
in the existing key scanning method in the PEPS module, the scanning sequence of different types of keys is disordered, so that the software of the PEPS module is complicated.
Therefore, the existing key scanning method cannot meet the requirement in practical use, so that an improved technology is urgently needed in the market to solve the problem.
Disclosure of Invention
The invention aims to provide a legal key scanning method based on a Bluetooth key function, when an effective electronic key and a Bluetooth key are in a vehicle at the same time, a clear scanning sequence of different types of keys is established through the design method, the disorder of using the keys can be effectively avoided, a three-step method is adopted to judge whether the legal key exists, and if the legal key is identified at any step, the vehicle can be used, so that the method is more convenient.
In order to solve the technical problems, the invention is realized by the following technical scheme:
the invention relates to a legal key scanning method based on a Bluetooth key function, which comprises the following steps:
step 1: a user opens the intelligent terminal and presses a vehicle starting key;
step 2: at the moment, the PEPS module in the vehicle drives the antenna to start to identify the traditional electronic key, if the antenna identifies the traditional electronic key in the calibrated in-vehicle range, the PEPS module judges that a legal key is available, then the PEPS module judges whether other power-on conditions of the vehicle are met, and if the other power-on conditions are met, the vehicle is allowed to be powered on;
and step 3: if the antenna cannot identify the traditional electronic key in the range, the PEPS module judges whether the Bluetooth key is valid, if so, the PEPS module judges whether the Bluetooth key is valid, then the PEPS module judges whether other power-on conditions of the vehicle are met, and if so, the vehicle is allowed to be powered on;
and 4, step 4: if the PEPS module judges that the Bluetooth key is invalid, the PEPS module drives the IMMO coil to search for the electronic key, if the electronic key is found, the PEPS module judges that a legal key is provided, then the PEPS module judges whether other power-on conditions of the vehicle are met, if yes, the vehicle is allowed to be powered on, and if the electronic key is not found, the action is stopped.
Further, intelligent terminal sets up to one of smart mobile phone, intelligent bracelet and intelligent wrist-watch, pairs through APP or the bluetooth of little letter applet and this car in smart mobile phone, intelligent bracelet and the intelligent wrist-watch, through virtual bluetooth key control vehicle, and do not confine to above-mentioned equipment, can also adopt other intelligent terminal that conveniently carry.
Further, adopt APP and believe little procedure a little in the intelligent terminal as the carrier, realize virtual bluetooth key control vehicle through APP and letter little procedure a little.
Furthermore, the intelligent terminal and the Bluetooth module in the vehicle are both low-power Bluetooth modules, so that the power consumption of the whole keyless entry and starting system is reduced.
Further, the method for determining the validity of the bluetooth key in step 3 is specifically,
the Bluetooth of the user side is opened, the user logs in the intelligent terminal through one mode of verification codes, fingerprint identification or face identification, the cloud side and the vehicle-mounted intelligent module are authenticated, after the authentication is passed, the vehicle-mounted intelligent module and the PEPS module are considered to be valid Bluetooth keys, and the PEPS module judges that the valid keys are valid.
Further, if the key cannot be found in step 2, step 3 or step 4, the PEPS module determines that the legal key is not available.
The invention has the following beneficial effects:
1. when the effective electronic key and the Bluetooth key are in the vehicle at the same time, the clear scanning sequence of the keys of different types is established through the design method, the disorder of using the keys can be effectively avoided, the universal key scanning method for the interior of the PEPS module is provided, the PEPS module software is further simplified, the trouble that a vehicle owner can use the vehicle only by carrying the electronic key is avoided, and the use experience of the vehicle owner is improved. And in the using process, the PEPS module drives the antenna to scan the electronic key and the IMMO coil scans the electronic key, and the dual scanning system ensures the accuracy of electronic key identification.
2. The invention adopts a three-step method to judge whether the legal key exists, if the legal key is identified in any one step, the PEPS module enters the next step to judge other power-on conditions, and if the other power-on conditions are met, the engine can be powered on and started, so that the method is more convenient and faster.
Of course, it is not necessary for any product in which the invention is practiced to achieve all of the above-described advantages at the same time.
