autodoip

DoIP (Diagnostics over IP) transport layer for automotive UDS communication — ISO 13400.

Installation

pip install autodoip

Quick Start

from autodoip import Endpoint

# 创建端点 — 监听 198.18.44.1:13400，等待 ECU 连接
endpoint = Endpoint(
    ip='198.18.44.1',
    ecus={
        0x1301: ('198.18.44.49', 0),     # port=0 忽略端口校验
        0x1302: ('198.18.44.50', 13400), # 精确匹配 IP + port
    },
)

endpoint.start()

# 查看连接状态
print(endpoint.connections())
# {0x1301: ('198.18.44.49', 0, True), 0x1302: ('198.18.44.50', 13400, False)}

# 切换到已连接的 ECU，发送诊断请求
endpoint.select(0x1301)
response = endpoint.send(bytes.fromhex('22DC06'))
print(response.hex(' '))

endpoint.stop()

API

符号	说明
Endpoint(ip, ecus, port, tester, config)	DoIP 端点。ip + ecus 必传
Endpoint.start()	启动监听，幂等
Endpoint.stop()	关闭所有连接
Endpoint.select(addr) -> bool	切换 ECU，成功返 True；未连接返 False 不切不退
Endpoint.send(payload) -> bytes	发送 UDS 载荷，返回响应。通信中断自动重连一次
Endpoint.connections() -> dict	{addr: (ip, port, connected), ...}
Config(accept_timeout=..., recv_timeout=..., ...)	传输调优参数，全部有默认值
ProtocolError	帧格式校验失败

Configuration

from autodoip import Config

Config(
    accept_timeout=1.5,   # accept 超时 (s)
    recv_timeout=3.0,     # recv 超时 (s)
    listen_count=5,       # socket backlog
    version=0x02,         # DoIP 协议版本
    msg_type=0x8001,      # Payload Type
    byte_order='big',     # 字节序
)

Requirements

• Python >= 3.14
• Zero external dependencies (stdlib only)
