Abstract

Unless constantly protected by overhead garages, an automotive vehicle, when parked and with its windows and sunroof opened or closed, is often subjected, respectively, to the risk of freezing or overheating its interior. Such extreme temperatures will reduce the life span of the electronic and mechanical components in or near the vehicle interior. Also, excessively high and low temperatures in the interior of the car would clearly cause a rather discomforting experience for the driver and passengers who subsequently seat themselves in it. This experience is keenly amplified for young children, elderly and those who are physically weak because of their reduced tolerance to discomfort.

Briefly, a method and apparatus is provided for automatically adjusting a vehicle'"'"'s window and sunroof positions after a vehicle operator has left a car unattended. The present invention includes a power window and sunroof system for an automotive vehicle. This system according to the present invention is activated only when the vehicle is presumably parked and left unattended by a vehicle operator. Once activated, the power window and sunroof system will be turned OFF automatically when the vehicle operator returns to drive the vehicle away.

The present invention also has a temperature sensing circuitry to be appropriately located somewhere in or near the interior of the vehicle. Once the system is activated, output of the temperature sensing circuitry would then be used to maintain a "comfortable" temperature range for the interior of the vehicle over the time period the vehicle is parked and left unattended.

Claims

1. A method for intelligently controlling the temperature of a vehicle after the vehicle is parked and left unattended;

the method comprising the steps of;

Coupling a vehicle micro-controller being located in the automotive vehicle and having access to a pre-defined temperature range which including a high value and a low value to an activation and de-activation evaluator, a temperature sensing circuit, and a power window system;

Detecting first by the activation and de-activation evaluator the vehicle being parked and left unattended by a vehicle operator, the first detecting step further including informing the vehicle micro-controller for activating said temperature-dependent system;

Detecting second by the activation and de-activation evaluator the vehicle operator returning to drive the vehicle away, the second detecting step further including informing the vehicle micro-controller for de-activating said temperature-dependent system;

Providing by a temperature sensing circuit a temperature reading of the vehicle interior in response to an access by the vehicle micro-controller; and

Directing by the vehicle micro-controller to cause the power window system to move its window panes to CLOSED positions if the temperature reading falling below the low value of the temperature range, the directing step further including causing the power window system to move its window panes to pre-defined OPENED positions if the temperature reading exceeding the high value of the temperature range.

5. The temperature-dependent system as claimed in claim 1 further includes a manual switch configured for the vehicle operator to bypass temperature-dependent system, and wherein the vehicle micro-controller causes the power window and the power sunroof systems to move their parts to the CLOSED positions if the temperature reading falling within the pre-defined temperature range.

2. An automotive vehicle having a temperature-dependent system for intelligently controlling the temperature of a vehicle interior after the vehicle being left unattended by a vehicle operator, said temperature-dependent system comprising:

a vehicle micro-controller located in the automotive vehicle and said vehicle micro-controller being operatively coupled to an activation and de-activation evaluator, a temperature sensing circuit, a power window system and a power sunroof system, said micro-controller having access to a pre-defined temperature range which having a high value and a low value;

the activation and de-activation evaluator including electronics to first detect the vehicle being parked and left unattended by a vehicle operator by requiring occurrences of an ignition key removed signal, a driver door OPENED signal and a subsequent driver door CLOSED signal, said evaluator further informing the vehicle micro-controller in response to such first detection for activating said temperature-dependent system, said activation and de-activation evaluator further including electronics to second detect the vehicle operator returning to drive the vehicle away, said evaluator further informing the vehicle micro-controller in response to such second detection for de-activating said temperature-dependent system;

the temperature sensing circuit located in the vehicle for providing a temperature reading of the vehicle interior in response to an access by the vehicle micro-controller;

the vehicle micro-controller being responsive to the temperature reading being in between the first high value and the first low value by directing the power window and power sunroof systems to maintain the temperature reading to be within the first temperature range over the time period the vehicle is parked and left unattended; and

the vehicle micro-controller causing the power window and the power sunroof systems to move their parts to CLOSED positions if the temperature reading falling below the low value of the temperature range, the micro-controller causing the power window and the power sunroof systems to move their parts to pre-defined OPENED positions if the temperature reading exceeding the high value of the temperature range.

3. The temperature-dependent system as claimed in claim 2 wherein the evaluator for the first detection of the vehicle being parked and left unattended by the vehicle operator further requires a door LOCKED signal and all signals occurring within a pre-determined duration.

4. The temperature-dependent system as claimed in claim 2 wherein the evaluator for the second detection of the vehicle operator returning to drive the vehicle away requires for system de-activation a driver door OPENED signal, a driver door CLOSED signal and a subsequent ignition switch ON signal, and all signals occurring within a one-minute duration.

6. The temperature-dependent system as claimed in claim 2 wherein the vehicle micro-controller causes the power window and the power sunroof systems to move their parts to the pre-defined OPENED positions if the temperature reading falling within the pre-defined temperature range, and one of the pre-defined OPENED positions providing a generally 10 millimeter opening for the power window and the power sunroof systems.

7. An automotive vehicle having a temperature-dependent system for intelligently controlling the temperature of a vehicle interior after the vehicle is parked and left unattended said temperature-dependent system comprising:
