Motor control also plays a key role in the
vehicle's body electronics and traction
systems. Body electronics and vehicle
dynamics encompass various systems
related to the vehicle's starting, stopping,
and steering. These systems include
auxiliary drives, electric power steering
(EPS), and braking systems. On the other
hand, traction inverter systems focus
on transforming electric power from the
battery into mechanical power for the
wheels. In both cases, the integration of
advanced motor control technologies
significantly enhances vehicle
performance, comfort, and safety.
One way that motor control technologies
impact these systems is by enhancing
driving comfort and efficiency. Modern
automotive body electronics systems
employ electric motors to replace
traditional mechanical components,
leading to smoother and more precise
operations. For example, EPS systems
utilize motor control to provide variable
steering assistance, which improves
handling and reduces driver effort,
especially at low speeds. Unlike
conventional steering systems, which rely
on an engine-driven pump, EPS systems
use an electric motor to assist the driver's
steering input.
