CONTROLLER OF AUTOMOBILE HEATER AUTOMATIC CONTROL SYSTEM Russian patent published in 2007 - IPC B60R16/02 B60H1/00 

FIELD: transport engineering; electrical equipment of vehicles.

SUBSTANCE: according to invention, heater fan mode selector switch and air distributing and saloon air temperature setters are provided made in form of step resistive modules. Computing unit receives measured signals from air distributing setter, saloon air temperature setter, saloon air temperature sensor and sensor of shaft turning angle of heater gate microgeared motor, and generates control signals for said microgeared motor and air distributing geared motor. Stabilized uninterrupted power supply unit supplies saloon air temperature sensor, sensor of shaft turning angle of heater gate microgeared motor and computing unit and computing unit at ignition switched off and completion of operation of computing unit following standard program with memozing numerical value corresponding to position of rod of reared motor at moment of switching off of ignition. Device contains housing, printed-circuit board, false panel, face panel with mask, holder with illumination lamp, light conduit for provision of uniform illumination of symbols, scales and signs on face panel and connector for connecting controller to supply circuits and external devices. Computing unit, stabilized uninterrupted power supply unit and other electronic units and connector are mounted on printed-circuit board. Holder with illumination lamp, latch-fitted module of air distributing setter, saloon air temperature setter module and heater fan mode selector switch are mounted at one side of false panel and printed-circuit board is secured by screws and light conduit is latch-mounted at other side. Controller skeleton formed on base of false panel from side of printed-circuit board is enclosed by housing, and from side of light conduit it is closed by face panel through mask.

EFFECT: improved manufacturability of controller.
