AVL Approach

Based on decades of engineering experience AVL is the only independent powertrain engineering company able to provide engineering solutions at all levels. With the experience gained over years across the complete powertrain, advanced methodologies and state-of-the-art tools have been developed to support the latest transmission and hybrid market requirements.

AVL's unique transmission control architecture is a perfect example of AVL's expertise in transmission controls. Unique AVL architecture enables customers to use AVL application software for varying drivetrain configurations equipped with different transmissions.

In recent years, the challenge for software development has become not only technical but also centered around the processes required to fulfill the increasing demand in terms of safety and robustness. AVL developed a unified software process which is applicable for projects with different scopes or demands, starting from concept verification to the serial production.

As a result of technical and process perfection, the development environment can also be easily shared with the customer's operation locally or even globally, which enables successful joint development projects.

An answer to the market challenges is given by AVL's development processes, advanced offline/online testing procedures and deep transmission control knowledge with the extended expertise combined from different disciplines.


Market Requirements

Modern powertrains are increasingly important due to the growing challenges of fuel economy and CO2. To fulfill these challenging requirements, new transmission structures e.g. integrated electrical machines, multi-element shifts etc. are currently being developed which require complex control strategies with cutting edge technologies in the control domain. The automated transmission market is also expanding to new markets which require both comfortable and efficient powertrains.

Further challenges like shorter development periods, safety demands, robustness and increasing diversification have to be managed with cost considerations firmly in mind.
