Changing customer preferences and market demands clubbed with environment protection norms have driven the use of advanced electronics in almost all the automobile systems. Automobile air conditioning, too, has marched a step forward with the introduction of “Automatic climate control systems” (popularly called “Automatic air conditioning”). Though the technical concept, per se, is already used widely in Room AC’s, it is only with the recent advancements in automotive electronics that it has found applications in the automotive air conditioning. A considerable number of vehicles in overseas markets are fitted with automatic climate control systems. India is not far behind as many of the high-end vehicles have built-in Automatic climate control systems. Maruti Udyog has taken the initiative in this direction by introducing “Automatic climate control” in its recently launched car.

Powertrain Control development has gone through many changes in terms of process, tools and practice at all OEM's across the geography. This is mainly driven by increased number of powertrain components for control, shorter development schedules, cost control, and the need to realize the potential of electronic control to increase the performance, efficiency, safety and comfort. With the significant advancement in Powertrain Controls and additions of electronic functions, it has become imperative to automate the controller development process in the V-cycle to reduce the time and make the process more efficient while detecting any logic failures upfront at the early stage of the development cycle. Traditional practices and tools of defining the controls cannot meet new requirements. Model Based Design (MBD) approach is a promising solution to meet the critical needs of powertrain control engineering to define the control logic and validate.
