CCP stands for ‘CAN Calibration Protocol’. It is a communication protocol used in the automotive industry for calibrating and configuring ECUs in vehicles. CCP is specifically designed to allow measurement and calibration tools to access and modify parameters, variables, and memory locations within the ECUs.

The main features of CCP include:

  1. Calibration Data Access: CCP enables read and write access to calibration and measurement data stored in the ECUs. This data includes various parameters, maps, and constants used to control the behavior of the ECUs and the overall vehicle system.
  2. Real-time Data Measurement: With CCP, real-time data from the ECUs can be measured, allowing engineers and technicians to monitor critical parameters and debug the system during runtime.
  3. ECU Flashing: CCP allows for the reprogramming or flashing of the ECU’s memory to update the software or firmware. This is essential for implementing software changes, bug fixes, or performance enhancements.
  4. Flexibility: CCP is a flexible protocol that can be used with various physical communication layers, such as CAN (Controller Area Network) or Ethernet, depending on the specific implementation.
  5. Security: To prevent unauthorized access and modification, CCP typically includes security mechanisms to ensure that only authorized users and tools can perform calibration and configuration tasks.

CCP is often used in combination with other automotive communication protocols like CAN (Controller Area Network) or XCP (Universal Measurement and Calibration Protocol). XCP is another calibration protocol that provides similar functionalities and is gaining popularity due to its broader range of capabilities and better performance.

Together, CCP and XCP enable automotive engineers and technicians to perform calibration, measurement, and flashing tasks efficiently and accurately during the development, testing, and maintenance phases of automotive software and control systems.
