Abstract

A ruggedized mobile computing system for a motor vehicle includes a ruggedized mobile computing device, which can be mounted in the trunk or other convenient location, and a suitable user interface system, such as a display screen, keyboard, etc., mounted in the vehicle cabin. The computing device can accommodate user-removable, plug-in electronic modules that perform specialized processing, communications, control or other specialized tasks relating in some way to the vehicle mission or purpose. The device has a ruggedized enclosure made of a durable material such as sheet metal or high-impact plastic. The enclosure can include a guard that protects cables extending from the front panel from being damaged or inadvertently removed. Cooling and warming systems can be included that maintain the enclosure environment within suitable operating temperatures in hot or cold weather. Some or all of the electronic or electromechanical elements, such as a disk drive, can be mounted with isolation mounts that protect them against harmful effects of mechanical shock and vibration.

Claims

1. A ruggedized mobile computing system for motor vehicles, comprising:

a user interface system mountable in an area of the vehicle immediately accessible to a driver; and

a ruggedized computing device, comprising;

a ruggedized housing having a mounting system for removably mounting the housing to a surface in the vehicle;

processor logic;

an interface for coupling the user interface system to the processor logic via a communication link; and

a power supply system connectable to vehicle electrical power.

2. The ruggedized mobile computing system for motor vehicles claimed in claim 1, wherein the housing includes a latch that can be mated with a plate mountable to the vehicle.

3. The ruggedized mobile computing system for motor vehicles claimed in claim 1, wherein the latch includes a key-operated security lock.

4. The ruggedized mobile computing system for motor vehicles claimed in claim 1, wherein the housing includes a guard portion extending from a front panel to which cables are connectable for protecting cables plugged into the front panel.

5. The ruggedized mobile computing system for motor vehicles claimed in claim 4, wherein the housing includes a handle for facilitating removal from the vehicle.

6. The ruggedized mobile computing system for motor vehicles claimed in claim 1, further comprising a plurality of fans for drawing air through the housing.

7. The ruggedized mobile computing system for motor vehicles claimed in claim 6, further comprising a filter disposed over an opening in the housing through which air is drawn by the plurality of fans.

8. The ruggedized mobile computing system for motor vehicles claimed in claim 6, further comprising a filter controller for sensing air flow and generating an indication to service the filter if air flow is below a predetermined threshold.

9. The ruggedized mobile computing system for motor vehicles claimed in claim 6, further comprising a fan controller for sensing ambient temperature and preventing the plurality of fans from operating if the ambient temperature is below a predetermined threshold.

10. The ruggedized mobile computing system for motor vehicles claimed in claim 1, further comprising:
