Method and apparatus for providing an automatic defroster function for a surface in a vehicle including a sensor for detecting the presence of mist or ice on such a surface, means for generating control signals, on the basis of the sensor data, for a number of functions in the car for an optimum defroster function on said surface, means for receiving these control signals, and means for receiving control signals from a temperature regulator in the car for a number of functions in the car. A number of the control signals from the temperature regulator are intended to control the same functions as the control signals for the optimum defroster function, and the same means are used for receiving control signals for optimum defroster function and for receiving some of the control signals from the temperature regulator. The means for receiving control signals are intended, in the event of conflict, to select those control signals that are designed to give the best defroster function.

Device and method for automatic defroster in cars

System and method for controlling a vehicle that includes sensing driver control information from each of at least two foot actuated pedals of a vehicle. The sensed information is electronically analyzed and a driver desired vehicle acceleration is determined from the sensed information. An acceleration affecting system of the vehicle is then controlled to urge the vehicle toward the driver desired vehicle acceleration. The sensed driver vehicle control information may be translated into an electronic format suitable for being electronically analyzed, but in most instances will already be in such a format and no translation is necessary. Both positive and negative determinations of driver desired vehicle acceleration are accommodated which generally correspond to desired faster travel and desired slower travel, respectively, when the vehicle is in forward motion. An electronic control command is computed and utilized to control the acceleration affecting Environmentally imposed effects on the vehicle are considered in the computation of the electronic control command that is utilized in the step of controlling the acceleration affecting The acceleration affecting system is configured to include a power supplying sub-system and a braking sub-system, the power supplying sub-system and the braking sub-system establishing opposed acceleration affecting sub-systems.
