Abstract: In order to solve the problems of high cost, low efficiency and difficult data acquisition of the existing differential lock automatic control algorithm experimental platform,the research group has developed a test platform for the automatic control algorithm of differential lock based on the model off-road vehicle, which collects vehicle status information by arranging sensors on a 1:8 model simulation off-road vehicle to collect vehicle status information and transmits it to the controller for calculation and processing, and observes the vehicle status information in real time through bluetooth, providing technical support for verifying the automatic control algorithm of differential lock. This paper mainly introduces the design scheme, structural composition, sensor installation position and automatic locking and unlocking conditions of simulated vehicle nest differential lock, and verifies the effectiveness and reliability of the experimental platform. The development of this experimental platform provides experimental conditions for the subsequent transplantation of differential lock automatic control algorithm and provides an experimental basis for verifying the reliability of differential lock control algorithm.

摘要： 为了解决现有差速锁自动控制算法实验平台存在的成本高、效率低、数据采集困难等 问题，课题组研制了一款基于模型越野车差速锁自动控制算法试验平台。通过在一辆 1:8 的 模型仿真越野车上布置传感器采集车辆状态信息传输到控制器计算处理，通过蓝牙方式实时 观测传感器检测车辆状态信息，控制器判断车辆趴窝状态而发出控制指令从而对车辆差速锁 的锁止状态进行控制，达到车辆脱困的目的。该实验平台的研发为验证差速锁的自动控制算 法提供技术支持。文章主要介绍了该实验平台的设计方案、结构组成、传感器安装位置和模 拟车辆趴窝差速锁的自动锁止、解锁工况，验证了实验平台的有效性和可靠性。该实验平台 的开发为后续差速锁自动控制算法的移植提供了试验条件和为验证差速锁控制算法的可靠性 提供了实验基础。
