In the territories of the Russian North in connection with the operation and development of oil and gas complex is operated by a large Park, the hydraulic mobile machines. Operation of such equipment is difficult in conditions of low negative ambient temperatures due to changes in the thermal state of units, elements of machine systems. The hydraulic system unlike other systems of machines is distributed throughout the machine, has a large length, many elements. The heating efficiency of which depends on the order, the simultaneity of inclusion, taking into account the duration and intensity of heating of each element. This problem is solved by automating the process of thermal preparation of hydraulic machines. For this purpose the scheme of automation of process of thermal preparation of elements of the hydraulic drive of the mobile car is developed. The algorithm of the program of the control unit of the process of thermal preparation is presented. For example, heating the working fluid exhaust gases of internal combustion engines developed functional scheme of automatic control system by the process of heating the working fluid in the hydraulic reservoir.
