There is an increasing trend toward introducing mechatronic systems wherever possible. It is, therefore, no wonder that a certain type of mechatronic system is an integral part of every manufactured car. To speed up the development of such systems, new methods and various sophisticated tools are constantly being designed, with the aim to reduce the time and cost of development. Many intelligent mechatronic systems 16 being developed are related to the chassis and powertrain of vehicles. This article also deals with the development of a system associated with the powertrain of vehicles or, more specifically, the development of a mechatronic system for an automatic differential lock. The basic function of this system is to evaluate the slip of the wheels and powertrain shafts. The control system evaluates sensor signals from wheel speed sensors, the vehicle pedals, an air pressure sensor in the pneumatic circuit, feedback sensors, control switches and buttons, Controller Area NetworkCAN messages from other Electronic Control UnitsECUs, and touch displays. The system then sends the signals to the actuators which are assembled from the electrovalve, the pneumatic circuit, a feedback sensor, and a special dog clutch. When the electrovalve is opened, pressurized air is introduced into the pneumatic cylinder, thereby moving its piston with the bracket; this locks the special dog clutch. These actuators are located in the appropriate differentials or used to connect the front axle input shafts to the transfer case of the vehicle to activate all-wheel drive. The driver controls the system with three switches and one button. The first switch is used to set the automatic and manual control modes. The two other switches and the button are used to activate all-wheel drive and lock the rear inter-differentials, the rear axle-differentials, and the front axle differentials in manual control mode. Another option is to set up three driving modes for road, field, and terrain/snow on the touch display. Information on all-wheel drive activation or locking the relevant differentials is also provided on the display. This system was developed to improve the properties of the vehicles powertrain, improve fuel economy, and reduce tire wear. A vehicle fitted with this system is more environmentally friendly and protects the powertrain against inappropriate differential lock control by inexperienced drivers, therefore, the system is controlled automatically. The testing and the evaluation of this system was carried out in the form of prototyping, where a controller with a control algorithm was connected to the vehicle prototype. The powertrain of the vehicle prototype consisted of an engine, a transmission, a transfer case, a rear inter-differential, and four axles with an axle-differential. The powertrain enabled the front axles drive to be activated. In the area of drive control, differential lock, and all-wheel drive activation, the Zahnradfabrik Friedrichshafen Automatic Drive-Train ManagementZF ADM differential locking system described in 7,8 can be used for trucks. Another system is the Meritor driver-controlled differential lock (DCDL) . These two companies created a new ZF Meritor, so it can be assumed that DCDL is the same system as ZF ADM, i.e., a system that evaluates wheel slip. The control algorithm evaluates slip and locks or unlocks the relevant differentials. A dog clutch is used in the differential. There are a number of systems on the market that control torque distribution and the locking of differentials in passenger cars, such as Torque Vectoring. However, these systems cannot currently be used for trucks or special vehicles due to their high transmission torque. For this reason, it is necessary to use a dog clutch for differential locking. A similar system is introduced in this article describing the principle of the developed control algorithm and prototype testing on a vehicle6在可能的情况下，引入机电一体化系统的趋势越来越明显。因此，难怪某一类型的机电系统是每一辆汽车的组成部分。为了加快这类系统的开发，正在不断设计新的方法和各种复杂的工具，目的是减少开发的时间和成本。许多正在开发的智能机电系统16都与车辆的底盘和动力系统有关。本文还论述了与车辆动力总成相关的系统的开发，或者更具体地说，自动差速锁机电一体化系统的开发。该系统的基本功能是评估车轮和动力传动轴的打滑。控制系统评估来自车轮转速传感器、车辆踏板、气动回路中的空气压力传感器、反馈传感器、控制开关和按钮、控制器局域网CAN信息（来自其他电子控制单元ECU）和触摸显示屏的传感器信号。然后，系统将信号发送到执行器，执行器由电动阀、气动回路、反馈传感器和专用爪形离合器组装而成。当电动阀打开时，压缩空气进入气缸，从而使气缸的活塞与支架一起移动；这将锁定特殊的爪形离合器。这些执行器位于相应的差速器中，或用于将前桥输入轴连接到车辆的分动箱，以启用全轮驱动。驾驶员用三个开关和一个按钮控制系统。第一个开关用于设置自动和手动控制模式。其他两个开关和按钮用于启用全轮驱动，并在手动控制模式下锁定后差速器、后轴差速器和前轴差速器。另一个选项是在触摸屏上设置道路、野外和地形/雪地三种驾驶模式。显示屏上还提供了有关全轮驱动激活或锁定相关差速器的信息。开发该系统是为了改善车辆动力系统的性能，提高燃油经济性，减少轮胎磨损。安装此系统的车辆更环保，并保护动力总成免受无经验驾驶员不适当的差速锁控制，因此，系统是自动控制的。该系统的测试和评估是以原型的形式进行的，在原型上连接一个带有控制算法的控制器。车辆原型的动力系统由发动机、变速器、分动箱、后差速器和四个带轴差速器的轴组成。动力总成使前桥驱动被激活。在驱动控制、差速锁和全轮驱动激活方面，7,8中描述的Zahnradfabrik Friedrichshafen自动传动系管理ZF ADM差速锁
