What does PCM stand for?

Engines certainly have become more complex in the past 20 years with the whole show now run by a computer - the Powertrain Control Module or PCM.

Henkel has aligned its business structure into groups, which encompass the total vehicle, including: Automotive Coatings, focusing on core coating technologies including Bonderite, Aquence and e-coat products; Body Assembly, focusing on providing an integrated approach to addressing customer needs in NVH, structural and sealing solutions; Chassis and Exterior Components, focusing on the traditional frame and chassis segment with additional focus on steering and ride control, jobbers and coaters, wheels, brakes and exterior accessories; and Powertrain, focusing on engine and axle assemblies, transmissions, and powertrain control modules.

The powertrain control module cuts fuel to the deactivated cylinders.

The powertrain control module then computes the best spark timing, factoring engine speed, load and temperature, and a command is issued to the ignition control module, which charges and fires the appropriate coil.

In order to monitor the functionality of the fuel-efficient truck, the UC Davis team uses microprocessors to record data for each of the key systems controls in the vehicle, such as the powertrain control module, electric motor controller, battery monitoring system and emissions analyzer.

Chiodo, Supervisor, Custom Analog & Power IC Design at Visteon, "Ford Motor has been using Visteon Powertrain Control Modules with ON Semiconductor's Ignition IGBT's for optimum performance and emission control since the 1995 model year.

These teams can now collaborate on new features without having to actually build and test multiple prototypes of the automobile's powertrain control modules, significantly reducing future development time and costs.

The powertrain control module (PCM) pulses the IAC to obtain desired idle speed.
