Drivetrain Transmission Electronics

A part of the Electronic Control Unit (ECU), the Transmission Control Unit covers everything related to the transmission of your 1978 Chevrolet Nova. It ensures smooth gear shifts and optimal fuel economy and performance.It has the same principle as an ECU. Using input sensors it gathers data then compares it to its onboard memory and then sends out a signal accordingly to manage the output to what its memory recommends. All this is done to keep the performance optimal.

Electronic systems have become an increasingly large component of the cost of an automobile, from only around 1% of its value in 1950 to around 30% in 2010.Modern electric cars rely on power electronics for the main propulsion motor control, as well as managing the battery system. Future autonomous cars will rely on powerful computer systems, an array of sensors, networking, and satellite navigation, all of which will require electronics.

These control the transmission system, mainly the shifting of the gears for better shift comfort and to lower torque interrupt while shifting. Automatic transmissions use controls for their operation, and also many semi-automatic transmissions having a fully automatic clutch or a semi-auto clutch (declutching only). The engine control unit and the transmission control exchange messages, sensor signals and control signals for their operation.
