Articles and insights covering core automotive engineering concepts, design, and technology.
Modern vehicles contain dozens of electronic systems that must communicate with each other continuously. The engine control unit needs information from sensors, the anti-lock braking system needs wheel speed data, the airbag controller must react instantly during a collision, and the instrument cluster must display accurate information to the driver. Managing communication between all these…
CAN Signal Engineering • ECU Communication • Physical Value Conversion IDENTIFY SCALE & OFFSET (Convert CAN Raw Data to Physical Value) In CAN communication, ECUs transmit signals as raw binary or hexadecimal values. These values do not directly represent engineering units such as temperature, voltage, pressure, RPM, or speed. Scale and Offset parameters convert raw…
OVERVIEW Modern vehicles depends on fast and accurate communication between Electronic Control Units (ECUs). Engineers need a reliable way to measure data, calibrate parameters and test system behavior during development. This is where CCP and XCP play an important role. CCP, short for CAN Calibration Protocol, was introduced as the ASAM MCD-1 CCP standard. It…
