Process for ventilating the interior of a motor vehicle and ventilation system for the performance thereof
First Claim
1. A process for ventilating the interior of a motor vehicle having at least one openable closure operated by a drive motor, an interior temperature-setpoint value generator, at least one interior temperature sensor, at least one outside temperature sensor and a logic component having inputs, outputs and a computer portion, said process comprising the steps of:
- a. reading into the logic component an interior temperature-setpoint value;
b. reading into the logic component an interior temperature-setpoint value range;
c. measuring an interior temperature of the motor vehicle to obtain an interior temperature value;
d. measuring an outside temperature to obtain an outside temperature value;
e. calculating an upper threshold temperature value and a lower threshold temperature value in the computer portion from said interior temperature-setpoint value and said interior temperature-setpoint value range supplied to the inputs of the logic component;
f. controlling the drive motor from an output of the logic component to operate the closure in an opening direction when either of the following condition is determined to exist (i) if said interior temperature value is greater than said outside temperature value and said interior temperature value is greater than said upper threshold temperature value, or (ii) if said interior temperature value is less than or equal to said outside temperature value and said interior temperature value is less than said lower threshold temperature valueg. controlling the drive motor from an output of the logic component to operate the closure in a closed direction when said interior temperature value is greater than said outside temperature value and less than or equal to said upper threshold temperature value and less than said lower threshold temperature value.

Abstract
A process for ventilating the interior of a motor vehicle having a closure which can be opened by a drive motor, an interior temperature-setpoint value generator, at least one interior temperature sensor, at least one outside temperature sensor and a logic component with inputs, outputs and a computer portion. Existing components (sensors, logic components) of different units are used and operatively linked so that the driver is largely relieved of the need to manipulate numerous controls.
