Operational control of automobile's air-conditioning/ventilation system

摘要

The vehicle system controller (1) is based on a microprocessor (3) provided with memory (4) and a user interface (5). The latter employs e.g. a knob (6), rotatable on an arbitrarily graduated scale, by which the user varies the system operational settings. A rectangular pictogram on the interface clarifies these functions for the user. The vehicle system controller (1) is based on a microprocessor (3) with memory (4) and a user interface (5). The latter employs e.g. a knob (6), rotatable on an arbitrarily graduated scale, by which the user varies the system operational settings. Ideal conditions in the passenger compartment may vary from one user to the next, or, according to the physical state, at the time, of the same user. On a scale of 10, the user may select e.g. 5 as indicating satisfaction with the conditions; lower settings correspond to too cold and higher to too warm conditions, which the controller will correct, the more urgently as the set position approaches the extreme values 0 or 10. A rectangular pictogram on the interface opt. clarifies these functions for the user.
