전체 글 썸네일형 리스트형 Autonomous Driving_Control This “Control” part will replace the function of thinking and deciding of human’s brain, therefore we need to have very high level of technology to develop this artificial brain of autonomous driving system. If we analyze the brain function during driving, the sequence could be described : Perceive à Decision à Control Order. For the autonomous driving we need to have exactly same system working.. 더보기 Autonomous Driving_Sensors To realize autonomous driving, the system has to cover all the functions which we have as a perception system in our body, and in addition error-free function should be guaranteed. (Just one functional failure can cause lethal consequence in a road driving situation.) The most important hard working sensor in our body during driving is our eyes, the multi-dimensional functions to check short or .. 더보기 Autonomous Driving_Overview We can tell that the perormance of vehicles has reached a satisfactory level already. The maximum speed has reached over than 200kmh, even over 300kmh in case of luxury one. This means the vehicle speed has reached the level that a humanbeing cannot control with the feedback from driver’s eye body system. In the transmission side, there is already multi-step transmission over 11steps, and furthe.. 더보기 Wheel Alignment If we have a precise look on our shoes, we can find that our heel is designed always higher than toe. Why ? Why the heel should be always higher than ? The answer is because we walk forward, not backward. Like this simple difference in shoe design, we can design the shoe of a vehicle in this way also to give a better driving behavior by giving a small asymmetrical difference in suspension linkag.. 더보기 Clutch Assembly Clutch Assembly The clutch assembly is located between engine and manual transmission and it provides a mechanical coupling between the engine’s flywheel and input shaft of the transmission. To operate the clutch the driver should push the clutch pedal, then the mechanical linkage transfers the forces to the clutch assembly. Normally a clutch is always engaged (if no power is applied in the peda.. 더보기 ABS/TCS/VDC ABS (Anti Block System) was originally invented for airplane, because keeping weight balance in airplane is very hard because of long wing span if skidding happens at the tires during landing or taxing. Now, most of the vehicles are equipped with this ABS device and this helps quite a lot for safe driving. Slip Ratio When drivers pushed brake pedal, the pedal forces are converted into hydraulic .. 더보기 Kia unveils rendering of new K5 Kia Motors Corp. released the first renderings of its revamped K5 midsize sedan ahead of its official unveiling next month at the Seoul Motor Show. (rendering of K5 courtesy of Kia Motors Corp.) The second-generation K5 comes five years after the brand was first introduced to the auto market. The new design incorporates a wider look from its front radiator grille, giving the car a more sporty an.. 더보기 AWD AWD All Wheel Drive This is a type of driving which drives all four wheels to propel vehicle. Griping force between road surface and tire is much better than two wheel driving system, therefore a driver can keep the vehicle stance very stable during conering, slippery road surface or on the snowy road. As seen in the picture, there is one more differential (Center Differential) in the drive trai.. 더보기 이전 1 2 3 4 5 다음
