Applications of the Ackerman Steering and Electronic Differential in Modern Electric Drive Automotive Systems

Because the rise of the gas prices worldwide cannot be neglected, hybrid and electric vehicles are becoming a more viable alternative to the combustion engine vehicle. This article explores the possibility of using an Ackerman steering system together with an electric drive that uses one motor per wheel. Wheel-hub motors allow electric drive units to be located where their torque is needed: at the wheel. Here, they can also be used as brakes. In combination with a new system architecture, these motors not only enhance efficiency and safety, but also open the door to personalized cars through software upgrades. One advantage of the system is scalability, which means it can be adapted also for 4 wheel drive vehicles and the arrangement allows for the incorporation of every possible type of electronic assistance system. As a result, an experimental stand was built in order to check the capabilities of the system.
