Micro-hybrid or stop-start developments for automotive applications are continuously growing due to recent European regulations on emissions and pollution. A reinforced starter is able to ensure this new function in addition to the classical cold start. Such devices must be optimized, especially their process of commutation in order to minimize commutator and brush wears and keep the device running during the whole life of the vehicle. The starter performances are computed with the help of a FE model, coupled with circuit equation. Brush/segment contact resistance introduced in the circuit model has been measured and computed. An electrical arc model has also been developed and used in the model. Losses in sliding contact, and also during arcing contact, and other internal variable can thus be determined. © 2012 IEEE.

A selectively controllable heated wash system for a vehicle surface includes a wiper system control module operatively disposed in the vehicle and may be adapted to receive at least one sensed input. A fluid heating module is controlled by the wiper system control module, the heating module adapted to heat fluid therein to a predetermined target temperature, or to a preferred temperature determined as a result of recognition and analysis of the sensed input(s). Fluid is dispensed onto the surface from the heating module manually, according to predetermined parameters, or according to predetermined parameters determined at least in part as a result of recognition and analysis of the sensed input(s).
