Abstract: Perfection is relative and application specific. The perfect race CAR is not the CAR we use to commute to work. We need products for everyday use that are high quality, affordable, and solidly reliable. There will be times when we must use components that are not perfect, and this is when calibration becomes important. Calibration techniques reduce tolerances in imperfect manufacturing equipment while maintaining affordability.

Once relegated to the hinterlands of low cost indicatorlights, the LED is again in the spotlight of the lightingworld. LED lighting is now ubiquitous, from CAR headlightsto USB-powered lava lamps. CAR headlights exemplifyapplications that capitalize on the LED’s clear advantages—unwavering high quality light output, tough-assteelrobustness, inherent high effi ciency—while a USBlava lamp exemplifi es applications where only LEDs work.Despite these clear advantages, their requirement forregulated voltage and current make LED driver circuitsmore complex than the venerable light bulb, but some newdevices are closing the gap. For instance, the LTM®8040μModule™ LED driver integrates all the driver circuitryinto a single package, allowing designers to refocus theirtime and effort on the details of lighting design criticalto a product’s success.

Abstract: As electronic systems take over many of the mechanical functions in a CAR—ranging from engine timing to steering andbraking—there is a growing concern about fault tolerance. There should not be a single point of failure that would prevent a CAR fromat least "limping" off the road or making it to the nearest service station. Redundant systems, watchdog timers, and other controlcircuits are used to reroute signals and perform other functions that ensure that a vehicle can safely make it off the road when afailure occurs.

针对目前汽车追尾事件频发问题，提出一种防汽车车前和车后追尾的安全装置设计。该设计以高性能、低功耗的8位AVR微处理器ATmega8L为核心，结合霍尔式车速传感器、激光雷达测距装置和MMA7260QT加速度传感器，能够兼顾车前和车后，摒弃以往设计中只考虑车前或车后单一性缺点，尤其适用于高速、夜晚或新手行车。 Abstract: Aiming at the high frequency of vehicle rear-end collision，a safe device design of anti-vehicle rear-end collision is presented.In the design，the high-performance，low-power8-bit AVR microprocessor ATmega8L is utilized as a core combined with Hall-type speed sensor，laser-radar ranging devices and the acceleration sensor MMA7260QT.The design considers both the front and back of a CAR，and overcomes the drawbacks of former designs in which only the front or the back of the CAR is considered，so it is especially suitable for high-speed，night or the beginner’s driving.

The model consists of two systems, a climate control system and an electrical system. This allows for examination of the loading effects of the climate control system on the CAR s electrical system.

Parking Lot Simulation： Parking lot attendants often park CARs bumper-to-bumper, several CARs deep. This maximizes the number of CARs they can fit into a parking lot at the expense of complicating the process of retrieving someone s CAR when they want to leave. Consider the case of a person wanting to leave the parking lot but their CAR is parked in the back of a row of CARs. In this case, all the CARs parked in front of this person s CAR must be temporarily moved to allow this person to leave.
