Catch your vehicle Data via cheap CAN bus Tool

Purpose:

這個專案是利用便宜的方案去抓取你的車子CANBUS的資料.

This project uses a cheap solution to capture your car’s actionable information of CANBUS data.

Architectures:

利用OBD2接頭延長線連接汽車, ELM327 and CAN Hacker module (ESP32+MCP2515).
再使用手機TORQUE APP 讀取車子的資訊並且利用PC的CANHACKER software接收資料並儲存以利後續分析PID資料.

Use the OBD2 connector extension cable to connect the car, ELM327 and CAN Hacker module (ESP32+MCP2515).

Then use the TORQUE APP on your mobile phone to read the car's information and use the PC's CANHACKER software to receive the data and store it for subsequent analysis of the PID data.

OBD2(On-Board Diagnostics 2)

OBD-II systems provide access to health information and access to numerous parameters and sensors from the Electronic Control Units (ECUs). Thus, the OBDII system offers valuable information, including diagnostic trouble codes when troubleshooting problems.

if your car was manufactured after 1996, it features a Diagnostic Link Connector (DLC) or OBD2 port.

ELM327(Bluetooth interface)

ELM327 device acts as a bridge between the computer/mobile and the car. The OBD adapter is attached to the car's physical 16-pin OBD connector plug (OBD2 port), typically located near the dashboard below the steering wheel.

There are different types of interfaces that the ELM327 adapters can have, for example, Bluetooth, WiFi, USB, or serial port. For the best option for your needs.

Torque APP is for Android phones to use it with the ELM327 devices.
