Although this may be negligible for a computer plugged into the wall, in a car this is the battery-draining equivalent of leaving the dome light on. Thus, a full power down is necessary. Also, many of the shutdown circuits used in conjunction with car PCs completely cut power to the PC, sometimes quite abruptly, making even hibernation (the saving of the system state to disk) out of the question.
Waiting 30-60 seconds for a PC to boot once you get in your car is annoying and keeps car PCs out of the mainstream. When auto manufacturers specify in-car systems such as navigation, they usually insist on very, very rapid boot times, such as 100 milliseconds until the splash screen appears or 300 milliseconds until the system is usable.
The late John Muir took a philosophical approach to waiting for slow starts in his 1969 book How to Keep Your Volkswagen Alive, where he recommended rolling a cigarette and getting a good toke going, by which time the car will be warmed up and ready to drive. However, as smoking anything but cannabis has been all but outlawed (in California at least), the only solution that remains for car PCs is to reduce boot times.
CarPC . Slide the computer into the car
The main problem solved by CarPC – a union of all the multimedia, navigation and other systems of the car to increase comfort and convenience of all these systems. Furthermore, the presence computerate allows virtually unlimited opportunities to expand these systems to easily add new systems, without requiring changes to existing modules. Many of the systems implemented by CarPC available as separate solutions (eg, navigation, multimedia). And, of course, you can use these multiple independent devices.
But as a rule, the ability of all these devices are limited, and they do not lend themselves to further modernization. In the case of computerate – flexibility and scalability of the system in the complex are provided. And, very important factor, especially critical for the car – easy to use. Drivers must be as comfortable as possible, but his attention must not be dissipated. Computer for the car to focus the management of all systems in one place and provides for this convenient and intuitive interface, easily customizable for personal preferences. This interface is implemented on the basis of hardware and software consisting of a touch screen and the wrapper, which the “superstructure” of the operating system and optimized for touch input method (control of fingertip).
