摘要
智能化、网联化推动汽车行业转型升级,控制器硬件系统正不断的向着更高性能的方向发展。随着智能驾驶控制器的器件应用越来越多、计算处理能力越来越高、接口越来越丰富、传感器负载越来越大,对电源系统的需求不论是在电源电压的种类上、电流大小上、供电时序上都与传统控制器的供电需求产生了极大的变化。面对新的电源系统的需求,本文旨在对智能驾驶控制器的电源系统的变化展开详细的分析讨论,对智能驾驶控制器的电源系统的变化与设计方案给出建议。
At present,the development of intelligent and connected technologies promotes the transformation and upgrading of the automotive industry,which also gives controller hardware system a boost to develop towards higher performance.Therefore,intelligent driving controller devices are applied more and more extensively;the computer processing is more and more powerful;the interface becomes more and more abundant;the loads that connected to the sensors are more and more plentiful.As a result,the demands for power system,no matter in the voltage types of power,current size or the power supply timing,are changing a tremendously with the traditional ones of car's controller.Facing the demands of the new power system,this paper aims to give a detailed analysis and discussion on the changes of the power system of the intelligent driving controller,and give some suggestions on the change and design of the new power system of the intelligent driving controller.
