About

Automatic transmission hydraulic control technology

Hydraulic control enables smooth and efficient shifting of gears ensuring power is effectively transferred from the engine to the wheels. To ensure the proper functioning of the automatic transmission hydraulic control, the system must maintain precise pressure levels within safe operating limits. This requires the use of pressure regulation mechanisms and pressure sensors. To ensure highest level of safety, systems should be designed according to ASIL standards, such as ASIL-C and ASIL-D.

Infineon plays a crucial role in this control module by providing a comprehensive product portfolio that includes microcontrollers, sensors, and more. These components are essential for collecting and processing inputs, executing control algorithms, and generating output signals. By utilizing Infineon's offerings, the hydraulic system can be effectively and safely managed, ensuring the automatic transmission operates properly.
