The throttle motion control determines the relationship between accelerator pedal position and throttle opening, in particular the rule governing the transition from one position to another. The choice of transition rule is based on sensing the driving style of the driver of the vehicle. The driving style is determined by computer applying a set of fuzzy logic rules to translate a number of input ...

The invention concerns the transformation of expanded polymers, in particular styrene polymers of the polystyrene type and styrene copolymers.
