This example shows you how to track the 2-D or 3-D position of a Bluetooth® low energy (LE) node by using Bluetooth® Toolbox.
Using this example, you can:
Simulate direction-finding packet exchange in the presence of radio frequency (RF) front end impairments, path loss, and additive white Gaussian noise (AWGN).
Track the node position by using Bluetooth direction-finding features and position estimation techniques.
Improve the location accuracy by using a Kalman filter from Sensor Fusion and Tracking Toolbox™.
常用车辆CAN总线通讯协议,大多直接采用SAE-J1939的形式制定。电动汽车首先遇到了电池系统,电机系统等新加入电气需要重新设定PGN码等问题。CAN协议始终处在诸侯割据的状态。在过去的几年中,国家及相关机构也一直在对电动汽车的CAN通讯协议进行研究,希望形成统一的协议体系。统一的CAN协议,首先是零部件供应商的福音。当前主流主机厂,每家都有自己的整车通讯协议,各个供应商,需要根据整车厂的定义,修改零部件的CAN协议。
制定电动汽车的CAN协议,基本的思路是在SAE-J1939的基础上,根据自身电动汽车的需求,做出必要的调整。
