Hello all, With all-electric car designs becoming more popular, I was wondering if it was really necessary to have all that mechanical linkage in the front of an automobile to steer. Assuming independent electric motors for each wheel, and drive-by-wire technology, a simple alteration in wheel speed for the wheels on one side of the car could steer it (like tanks and their treads). Wheel speed, steering wheel input, and other data could easily be processed and made into a steering system. Has anyone seen any concept cars like this, or designs promising such a system? Can anyone think of major drawbacks? Thank you ::: I'm not sure if this should be in Elec. or Mech. engineering forums, I apologize if it is incorrectly labeled.
