Claim 13

An automatic venting system for the passenger space of a vehicle, comprising: means for sensing precipitation falling on the vehicle; means for determining the temperature of the passenger space of the vehicle; a plurality of venting elements, selected from the group consisting of windows, sunroofs and convertible tops, in communication with the passenger space of the vehicle; drive means for operating each of said venting elements, each said drive means including an electric motor; control means, responsive to said means for sensing and said means for determining, for commanding in a first mode each said motor to open its corresponding venting element when the temperature of the passenger space rises above a preselected threshold to accomplish venting of the passenger space, and for commanding each said motor to close its corresponding venting element when precipitation is detected; said control means including means for commanding in a second, security mode each said motor to immediately close its respective venting element regardless of whether precipitation is sensed; said control means further including means for commanding in a third mode selected ones of said motors to open, when the temperature of the passenger space rises above the preselected threshold, corresponding selected venting elements until precipitation is detected and for commanding nonselected ones of said motors to close corresponding nonselected venting elements regardless of whether precipitation is sensed; and means, actuated by an operator of the vehicle, for selecting one of said first, second and third modes for said control means.

Claim 14

The venting system of claim 11 further including means for enabling said control means to command said motors.

Claim 15

The venting system of claim 12 further including timer means, responsive to said means for enabling, for signalling said control means to command closure of said venting elements when a predetermined period has elapsed.

Claim 16

The venting system of claim 11 further including intruder detection means for placing said control means in said second mode when an intruder is detected.
