PDUR communication interface routing and PDU transmission mode and variable length DLC I-PDU AutoSAR
Interface routing is an important part of realizing data communication between different control units inside the vehicle in the automotive field. As a communication interface routing technology, PDUR (Protocol Data Unit Router) plays a key role in automotive electronic systems. This article will introduce in detail the concepts and applications of PDUR communication interface routing, PDU transmission mode and variable-length DLC I-PDU AutoSAR.
- PDUR communication interface routing
In modern vehicles, the key task of communication interface routing is the correct and efficient transfer of data between different control units. As a communication interface routing technology, PDUR can realize orderly data transmission and routing selection. It is responsible for monitoring and managing the transmission of data packets, and delivering data packets from the sender to the receiver according to specific routing rules. The PDUR communication interface routing module usually includes the following important functions:
- Routing management: define and manage the transmission path of data packets to ensure the correct transmission of data.
- Packet filtering: Filter and screen data packets according to specific conditions, and selectively forward or discard packets.
- Buffer Management: Maintain receive and send buffers to ensure efficient data transmission.
- Performance monitoring: Real-time monitoring of performance indicators of data transmission, such as delay, throughput, etc.
Below is a sample code that demonstrates the basic structure and functionality of PDUR communication interface routing:
// 定义数据报文结构
typedef struct {
uint8_t data[8];
uint32_t id;
} PDU;
// PDUR通信接口路由模块
class PDUR {
public:
void route(PDU pdu) {
// 根据路由规则将数据报文转发给相应的接收方
// ...
}
void filter(PDU pdu) {
// 根据条件过滤和筛选数据报文
// ..
