01 IIC Bus (Inter－Integrated Circuit) I2C (Inter-Integrated Circuit), also known as IIC or I2C bus, is a serial communication protocol used to connect multiple devices over short distances. It was first introduced by Philips in 1982 and is now widely used for communication between embedded systems, sensors, memory, and other peripheral devices. Here are some … Read more
In automotive Passive Entry Passive Start (PEPS) systems using low power Bluetooth® technology, drivers enter and start the engine using a key card that communicates with the car’s access system (instead of a traditional key). Figure 1 shows a typical architecture of low power Bluetooth PEPS inside the vehicle. This architecture includes a central smart … Read more
The charging system is an important foundational support system for new energy vehicles and is a key condition for the industrialization and popularization of new energy vehicles, significantly impacting its industrial development. Currently, the charging modes are divided into AC and DC. New energy vehicles that support AC mode are equipped with on-board AC-DC converters … Read more
Introduction RS-485 and CAN are both serial communication protocols. They allow for the arrangement of multiple devices within a single system, significantly reducing cable lengths. Their differential design is suitable for environments with strong interference, and both use 120 Ω termination resistors, equipped with internal over-voltage circuits for fault protection.RS-485 and CAN have many similarities, … Read more
1 CAN Bus The Controller Area Network (CAN) is a serial communication network with a high level of safety that supports distributed real-time control. It first appeared in the automotive industry in the late 1980s. Its basic design specifications require high bit rates, strong electromagnetic interference resistance, and the ability to detect any errors that … Read more
As automotive consumers increasingly demand safety, comfort, and intelligence in vehicles, automotive bus technology has rapidly developed. The use of in-vehicle bus systems simplifies the number of harnesses, enables intelligent information exchange, and connects all control units through a network bus system for data transmission. Each ECU unit can exchange data at any time to … Read more
Looking Beyond the Phenomenon to the Essence Functional Signal Signal communication is a basic function of the vehicle ECU; without it, nothing can be discussed! This can be plainly stated as dbc and HIL, which are the starting points of ECU’s basic capabilities~ Bus 10[2] discusses the release of excel2dbc tool 2.0.2, adding signal groups … Read more
