Now, during my planned one-year stay in the headquarters, I'm part of the team developing the software for automatic transmission systems for passenger cars. The transmission system software consists of several software components, including Application Signal Conditioning, Gear Shift Strategy, Electrical Transmission System Software (ETSYS), Drivetrain Control (all-wheel drive) and Driver Interface. However, my team handles the development of Application Signal Conditioning and ETSYS components.
The Application Signal Conditioning component works with the CAN interface, performing signal processing and local diagnostics as well as filtering and determining initial values. This component acts like a signal processor of the raw sensor values to produce meaningful values for the physical signals such as engine torque, vehicle speed, transmission temperature and more. After we obtain the accurate values from this component, its signal values are sent to the other software components for the further calculation.
