Regarding the evolution of automotive electronic and electrical architecture, the most discussed in the industry is the six stages of electronic and electrical architecture development proposed by Bosch, as shown in the figure. Bosch divides the whole vehicle EEA into six stages: Modular, Integration, Domain Central

A soft starter is a device used for starting and controlling motors. It can effectively reduce the current shock when the motor starts, extend the service life of the motor, and improve the stability of the system. In the design of a soft starter, the AC voltage regulator of the main circuit plays a vital role. This

CATL has launched the Xiaoyao battery designed specifically for extended-range electric vehicles and plug-in hybrid electric vehicles . The pure electric range of extended-range electric vehicles/hybrid electric vehicles equipped with Xiaoyao batteries can reach more than 400 kilometers, and it also su

The global notebook computer market has long been dominated by international giants such as HP, Dell, Apple and Microsoft. Among Chinese brands, Lenovo is the only one that stands out, while other local brands have a relatively small market share. However, as the "world's factory", China undertakes about

In the wave of changes in the automotive industry, semiconductor technology is like a surging power, driving the industry forward. When you sit in the car, press the start button, and enjoy the smooth driving and precise navigation service, you may not realize that there is a small but powerful force behind all this

Audi has spent a lot of time building up its electric drive system, which we have introduced before. Today, we will continue to share Audi’s choice of motors. ● The system output of the Q6 e-tron is 285 kW (combined power consumption kWh/100 km: 19.4-17.0 (WLTP)) ● The SQ6 e-tron has a system output

The speed control of thyristor DC motors is usually achieved by controlling the size of the thyristor opening angle α with phase-shift pulses. There are also chopper speed control, PWM pulse width modulation, and duty cycle modulation. Therefore, the motor current and voltage are different. Different power component

In autonomous driving, the perception of the vehicle's external environment requires the use of data from many sensors (Lidar, Camera, GPS/IMU). If the sensor messages received by the computing center are not uniform in time, it will cause problems such as inaccurate obstacle recognition. In order to perf

Yesterday we have implemented the GPIO button driver program by interrupt query. However, there is a disadvantage that when we put the application in the background, even if no key is pressed, the read function in the while loop of the application is constantly running, which seriously wastes CPU resources.

The day before yesterday we implemented a simple sysfs kobject driver, but did you find that we don’t understand a lot of things? The reason is that we don’t understand the working principles of sysfs and kobject. Although I have always been against contacting those boring knowledge points all day long, and I don’t

What is V2X? Vehicle-to-Everything (V2X) is a new generation of information and communication technology that realizes all-round connection and communication between vehicles and surrounding vehicles, people, transportation infrastructure and networks. Vehicl

The development of pure electric power depends largely on batteries, and companies with advanced battery manufacturing technology and power management technology will have a better chance of gaining a leading edge in the competition in the pure electric era. Tesla and Panasonic are working hard in this direction, an

On July 26, Arm announced on July 9 that it will stop supporting the open source embedded operating system Mbed OS in July 2026 and will no longer maintain it. At that time, the Mbed website will be archived and projects will not be built through online tools. The news has sparked widespread discussion

In recent years, home fitness has received widespread attention. To get a truly convenient, efficient, and immersive fitness experience at home, AI fitness cameras and large-screen TVs are indispensable. With the diversification of home fitness needs and the continuous emergence of various smart terminals, smart cam

With the rapid development of the automotive industry , in-vehicle communication technology is also constantly improving. As an emerging connection standard, MIPI A-PHY, a high-speed serializer - deserializer (SerDes) physical layer interface designed for automotive applicat

Each S7-200 SMART CPU provides an Ethernet port and an RS485 port (port 0). The standard CPU additionally supports the SB CM01 signal board (port 1). The signal board can be configured as an RS232 communication port or an RS485 communication port through STEP 7-Micro/WIN SMART software. CPU Communication

CAN bus technology has been widely used in automobiles. With the promotion of new energy vehicles and autonomous driving technology, bus problems have also brought risks and challenges to the safety of automobiles. This article discusses the electrical, EMC, hardware and software of CAN bus from a system perspective.

A team from South Korea's Ulsan National Institute of Science and Technology has developed a breakthrough technology that can recognize human emotions in real time, which is expected to revolutionize various industries and provide next-generation wearable systems based on emotion services. The relevant paper was publi
