GM launches new powertrain control systems

Detroit, Michigan – GM Powertrain is debuting a family of powertrain control systems in the 2006 model that will ultimately be used across the majority of the company’s vehicle line-up.

Powertrain control modules manage such functions as fuel, throttle, ignition, emissions, shifting, and integrated functions such as trailer/towing modes, traction and stability control, air conditioning, antitheft systems, driver display information, speed/tachometer and much more.

The new controls will debut on the Chevrolet Corvette, Impala, Monte Carlo, HHR, Cobalt, Uplander, Malibu SS and Malibu Maxx SS; on the Cadillac CTS-V, XLR-V, STS-V and DTS; the Pontiac Solstice, G6 and SV6; the Buick Terraza; and the Saturn Relay.

Engineers will combine various activators and sensors to customize the systems to each model’s unique performance needs. The controllers also can be utilized in GM’s specialty vehicles and various emerging technologies.

GM first started using vehicle computers in 1979, to meet federal emissions standards; these computers managed six functions. Modern powertrain computers control more than 100 functions and are 56 times faster than the originals.
