Embodiment 1

[0069] like image 3 As shown, it is a preferred embodiment of the PEPS control method based on Lora communication, and its execution flow is as follows:

[0070] S1. The user holds the smart key close to the side of the car, and presses the door handle button or pulls the door handle to notify the vehicle that the vehicle now needs to be unlocked / ignitioned;

[0071] S2. The LF transmitter module of the controller drives the low-frequency antenna, and the LF notifies the MCU of the request for unlocking / ignition, and the MCU wakes up the Lora module;

[0072] S3. The smart key LF receives the signal, and sends the received signal strength to the MCU to determine whether the smart key is within the valid range of calibration;

[0073] S4. If it is determined that it is within the valid range, the Lora module of the smart key sends the key encryption ID to the controller; if it is determined that it is not within the valid range, it returns to S1, and the user continues to app...

Abstract

The invention relates to the technical field of vehicle control, and in particular relates to a PEPS control system and method based on Lora communication. The system comprises an intelligent key and a controller, the intelligent key comprises a first MCU control module, a first Lora communication module and an LF receiving module, the controller comprises a second MCU control module, a second Lora communication module, an LF transmitting module and a driving circuit, the first MCU control module is used for receiving an RSSI signal sent by the LF receiving module, sending a key authentication ID signal to the second Lora communication module, and sending an unlocking / ignition signal to the second MCU control module after a verification passing signal fed back by the second MCU control module is received; and the second MCU control module is used for controlling the LF transmitting module to wirelessly communicate with the LF receiving module when receiving a door handle signal, performing key authentication after receiving the key authentication ID signal sent by the second Lora communication module, and controlling the driving circuit to execute an unlocking or ignition action after receiving the unlocking / ignition signal sent by the first MCU control module.

Description

technical field [0001] The invention relates to the technical field of vehicle control, in particular to a PEPS control system and method based on Lora communication. Background technique [0002] With the rapid development of technology, the demand for PEPS (Keyless Entry and Start System) is increasing, and it has become the standard configuration of many economical models. For cars equipped with PEPS system, the user can complete the operation of opening the door and starting the vehicle without pressing the remote control button on the smart key or the key inserting and removing the lock cylinder. Just carry the key with you at all times by pressing the trigger button on the door handle or the one-key start button. [0003] The PEPS system is divided into two parts, PE keyless entry and PS keyless start. Keyless entry means that when the user wants to unlock and enter the car, he does not need to take out the traditional key and insert it into the door lock to unlock it...
