先进驱动辅助系统中传感器的迅速使用
当人们想到汽车传感器系统时,可以预见到全球定位导航系统。然而,帮助失去的司机并不是汽车电子和传感器系统增长最快的部门的推动力。今天的汽车安全技术的目的是防止事故,由于司机的错误,分心,嗜睡。
据ABI研究,先进驾驶辅助系统(ADAS)已经在一年的豪华车。对于2012年款的,然而,作为自适应巡航控制等功能,车道偏离预警、低速碰撞缓解将大批量模型的居民包括福特和奔驰C级苯。作为一个结果,据估计,全球ADAS市场价值近100亿美元的2011,蘑菇1300亿美元2015。
ABI将新兴的收入预测归因于传感器设计和制造方面的技术进步,它提供了更低的成本和更好的性能,并且开发了额外的特性,使系统对新车购买者更具吸引力。
哪个部分能解释那1300亿美元?让我们看看。
Lane departure warning (LDW) systems
Lane departure warning systems alert the driver when an unintentional lane departure is going to occur. The driver is then responsible to act. LDW systems alone are expected to reach a worldwide market value of more than $14.3 billion by 2016. There are two types of LDW systems on the market: camera-based and infrared systems.
Camera systems
In camera-based LDW systems, a forward-looking CCD or CMOS camera tracks visible lane markings. The lane markings on the road are used to calculate the lateral divergence and divergence angle from the center of the lane. Algorithms are used to estimate the vehicle’s future position. Image recognition software computes inputs for vehicle information including speed, yaw rate, and steering angle. If the system discovers that the vehicle is veering off its intended path, it warns the driver and the driver must take corrective action.
