Benefits of technology

This technology allows for better control over vehicles' movements during acceleration or deceleration without requiring manual adjustment from outside sources like engine torque or road conditions. It also improves overall performance when turning quickly on different roads while maintaining smooth operation under varying speeds.

Problems solved by technology

This patented describes two technical problem addressed by this patents: traditional electrical power stealing systems used on vehicles that require both fuel economy and stability during highway operation due to their limited range of motion. These issues make it difficult to design effective automatic power steeling (APS) mechanisms without sacrificing safety standards.
