- To address the problem of harmful emissions, the car industry is shifting toward zero-emission transmissions. Transmissions based on electric machines represent a more pertinent technical solution in moving towards this target. Hybrid cars can be seen as the connection between old solutions based on thermal engines and targeted solutions based on electric machines. The closer the industry can come to a solution based on electric machines, the less pollution it will create. Unfortunately, trying to retain the performance of conventional cars in the resulting hybrids can become very costly. Therefore, from the drivers’ perspective, the cost/performance ratio is well on the side of proven solutions, although these are more harmful to the environment. To address this issue, hybrid cars can be constructed as mild or strong hybrids, an attempt to optimize the cost/performance ratio so that more consumers will buy more environmentally friendly vehicles. This paper describes the new architecture of mild hybrids based on electrohydraulic components and dual-output internal combustion engines. The aim is to provide the zero-emissions mode achieved by strong hybrids, but with the cost of mild hybrids. This solution would provide an affordable hybrid platform and reduce the direct harmful emissions generated by standard cars operating in high-pollution scenarios such as traffic jams. In addition, it can offer fun to drive option as drifting and/or torque vectoring.
