[0002] In today's rapidly developing automotive industry, automotive control systems, as the core of the vehicle, have a stability and reliability that is directly related to the vehicle's performance and safety. Magnetic rings, as indispensable electronic components in automotive control systems, play a vital role. From engine control to braking systems, magnetic rings ensure the normal operation of various vehicle systems by precisely controlling and transmitting signals. In engine control systems, magnetic rings are often used as part of sensors, such as those in cylinder sensors. These magnetic rings measure the position and motion of the piston, monitoring the working conditions within the cylinder in real time to ensure stable engine operation.
