DETROIT - Siemens Automotive has crammed 20 of its latest technologies into one show car.
Not all of the features on Siemens' Isis concept car made their debut at the SAE International Congress and Exposition, but Ralph Krempl, Siemens marketing manager, said each of the technologies on board is scheduled for production within three years. They include:
'ProdMod,' an electronic transmission control module contained in the transmission casing. It is based on a concept Siemens calls 'mechatronics,' which merges electronic and mechanical controls in one unit. In the ProdMod transmission, all sensors, actuators and electronic control boards are built into the transmission to reduce cost and space usage.
A modular engine intake that contains air cleaner, electronic throttle body, variable-length plastic intake plenum, air-flow sensors and an electronic engine control unit in one assembly. Siemens says plastic intake modules are 64 percent lighter than equivalent cast aluminum.
A variable-rate airbag inflator with two propellant charges of varying strength. An electronic control unit determines crash severity, then decides whether to ignite one or both inflators in the steering wheel.
