Description

[0002] ECU (electronic control unit, i.e. computer control module) is the core component of the automotive electronic control system, and its core function is real-time monitoring, decision-making and control.

[0003] In today's era of rapid development of automotive technology, with the continuous improvement of the intelligent degree of automobiles, the functions possessed by vehicles are also increasingly rich and diverse. Under such a background, more and more automotive seats are equipped with automatic massage devices, which can cleverly simulate the pressing, kneading, and hammering actions of human hands, thereby effectively relieving the fatigue of the driver's waist, back, and other parts during driving, and improving the comfort and experience of driving.

[0004] The electronic control unit (ECU) as a key control component of the automobile plays a crucial role in the operation of the automatic massage device. It is the core equipment of the pneumatic installation device, responsible for accurately controlling the entire massage system. In actual operation, the ECU will receive rich data feedback from various sensors distributed in key parts of the seat, which can sense the state of the seat and the body posture of the driver in real time. After receiving this data, the ECU will quickly perform complex calculations and logical decisions, based on pre-set control strategies and algorithms, and through precise analysis and judgment, finally output corresponding control signals. These signals will be accurately transmitted to the execution end, i.e. the specific massage execution components, to drive them to make corresponding actions, achieving the massage operation on the driver's body and relieving fatigue.
