随着使用条件与工作环境的愈发严苛,传统CAN总线的速率与带宽不能满足使用要求,CAN FD总线应运而生。但是CAN FD总线的发送速率却受到了自身延迟的影响,必须使用发送延迟补偿机制才可以突破发送速率的限制.本文分析了发送速率受限的原因,并提出了一种自动控制的发送延迟补偿方法,在自研控制器中进行了实现.控制器通过实时报文的发送情况灵活开启补偿机制,可以动态的定位补偿机制中二次采样点的位置,最终可以提高控制器整体的稳定性与灵活性.
With the using conditions and working environment become more and more severe
the rate and bandwidth do not meet the requirements of traditional CAN bus
CAN FD bus arises at the historic moment.But the sending rate of CAN FD bus influenced by its delay
must use the transmission delay compensation mechanism.The paper analyses the reasons of the limited transmission speed
and put forward a kind of automatic transmission delay compensation method
whichimplemented in independently developed controller.The controller can flexibly turns on the compensation mechanism through real-time message
which can dynamically locate the position of the secondary sample points and ultimately improve the stability and flexibility of the controller.
