Abstract Battery electric vehicles with automatic transmissions are a new rapidly growing segment of electric vehicle and automatic transmission type configured for such applications. A promising direction of their development is integration of mechatronic control systems of automatic transmissions and electric drive, i.e. transition to integrated power units of battery electric vehicles. Pre-defined criteria are required to formulate the specifications for the design of the mechatronic control systems for such a unit. However, not only for mechatronic control systems, but also for battery electric vehicles with automatic transmissions themselves, sufficient experience in production and operation has not yet been accumulated, which determines the relevance of this article. Its purpose is to formulate approaches to the development of specifications on the emerging mechatronic control systems for automatic transmissions of integrated battery electric vehicles power units with automatic transmissions. The analysis (according to the formed information base) of the set of general requirements is carried out to the designs of close analogues — modern mechatronic control systems of automatic transmissions of hybrid electric vehicles, as well as the results of optimization of their parameters, characteristics and control algorithms of stage shifting processes of automatic transmissions for application in battery electric vehicles. It is shown that the compositions of basic functional properties of mechatronic control systems of automatic transmissions in battery and hybrid electric vehicles largely coincide. As a result, the composition of a set of basic criteria is formed for the evaluation of mechatronic control systems of battery electric vehicles. Based on the results of expert evaluation and analysis of analogues that meet modern requirements and are close to the types of domestic equipment, the basic specifications are proposed to the composition and functional characteristics of mechatronic control systems of automatic transmissions of power units of battery electric vehicles power (taking into account the private specifications to the subsystems included in them). The specification lists and their evaluation criteria include a number of established technologies in the global automotive industry. Taking into account that their practical application requires systematized information, which is difficult to find in the Russian-language presentation, the necessary explanations are given.
