Solar power generation has become one of the most important renewable energy sources on Earth, but have you ever thought about what would happen if we could collect solar energy in space? In space, there is no atmosphere to block the sunlight, and with no day-night cycle, solar radiation can be received continuously for 24 … Read more
Level ShiftersLevel shifters – converting voltage from low to high Driving logic signals from a low power rail to a high voltage rail is a critical issue. Under-driven signals can lead to degraded rise and fall times at the receiving end. This, in turn, can result in higher switching short-circuit currents and reduced noise margins. … Read more
After years of low-power hardware design (the hardware and software design in the company are separate, and I have always worked on hardware, often facing the challenges of low-power production incidents), one common issue is that the IO configuration is not set correctly before the microcontroller enters sleep mode. The main problems with the product … Read more
Industrial automation equipment is usually not associated with “low power consumption”; however, in special scenarios such as remote monitoring stations and mobile devices, enabling the S7-1200 to enter “energy-saving mode” becomes necessary. This is akin to modifying a family sedan into an off-road vehicle, requiring a series of professional modifications, but it is absolutely feasible. … Read more
On April 7, Red Star Capital reported that several consumers have complained on platforms about the limitations of connected car features due to the shutdown of 3G networks, affecting brands including Great Wall Motors’ Haval and Wey, Chery New Energy, Dongfeng Honda, and Jianghuai Automobile. In response to this situation, 4S dealerships have proposed that … Read more
Recently, I have been discussing this topic with many friends, and there are many realistic changes in the situation, especially since we are at the beginning of the 13th Five-Year Plan, where everyone is deeply exploring this industry. I think we can look at this from two parts: 1) ADAS We should take a closer … Read more
Advanced Driver Assistance Systems (ADAS) are revolutionizing the automotive industry by enhancing vehicle safety, reducing accidents, and improving driving comfort. With an increasing number of regulations mandating the inclusion of ADAS features and consumer demand for safer vehicles, the market for ADAS-equipped cars is rapidly growing. Consequently, the demand for skilled professionals in this field … Read more
This article focuses on the wake-up, sleep, and reset of the ECU, examining whether your understanding aligns with these concepts. 1. ECU Wake-up To clarify the ECU wake-up process, we must study the corresponding hardware schematic. The essence of ECU wake-up is to supply power to the ECU. For better understanding, this article simplifies a … Read more
1. Characteristics of Automotive Electronic Control Unit Repair The automotive electronic control unit (ECU) is the core component of various automotive electronic control systems. When faults occur in these systems, many issues may be related to the ECU. However, compared to other components and circuits in the automotive electronic control system, the failure probability of … Read more
Five years ago, a new adjustable ECU/ECM claimed to be “unhackable” and dominated the market at that time; it was the GM E41 ECM Services (L5P). This ECU/ECM first appeared on the L5 Peter Max truck in 2017, and many believed that such ECUs/ECMs could not be hacked or tuned. As experts from the external … Read more
