An Introduction to the New Visual Safety System of Cars

The automotive industry is affected by the economic crisis at the present time. Safety and environmental protection is becoming the orientation of its development, leading manufacturers to produce a satisfactory product.

Safety is the most important element of a new car to customer feedback. The security system can guarantee the safety of driver, passengers and pedestrians, and reduce the incidence of accident it is still rapid growth, such as advanced driver assistance. Apart from the airbag, the new active safety system also applies to automobiles increasingly. As the rear view system, care system alert, lane-warning system, light control system, anti-collision and so on. There is a growing urgency for the design of car environmental protection to reduce energy consumption and greenhouse gas emissions. Apart from traditional media, different types of replacement power is implemented, such as ethanol-powered vehicles, hybrid and electric vehicles and battery electric vehicle.

So let's get to know something about the security system monitor. The image transducer with high dynamic range and the system directory protocol to create a new era of automotive vision system. For example, the warning signal on the system rear view camera to ask the driver for the change in size and color, warning care system can record and analyze the movement of the eyes through the camera emits infrared acoustic signal when the driver's eyes is closing for a long period of time, the lane warning system can monitor vehicle position for the camera.

The security monitoring system is based on the above systems visible faces some challenges such as low environmental light intensity. Apart from the camera, high-speed parking sensor is one of the main components in the system of active safety. The visible system software has some shortcomings, despite the high speed can use the advanced semiconductor technology to meet the high demands of active safety system. Scientists are trying to use SiGe chips to radar design, especially the application of remote inspection of the cars.
