Ohjauskulmaa

Ohjauskulmaa, often translated as steering angle, refers to the angle at which the wheels of a vehicle are turned relative to the vehicle's longitudinal axis. This angle is controlled by the driver through the steering wheel and is crucial for directing the vehicle's path.

The range of steering angles varies depending on the vehicle's design and intended use. For passenger cars, typical steering wheel movements translate to a wheel angle of up to approximately 35-40 degrees in each direction. Larger vehicles, such as trucks or buses, often have a more limited steering angle to maintain stability. Off-road vehicles, on the other hand, may be designed with a wider steering angle to improve maneuverability in challenging terrain.

The steering system translates the driver's input into changes in the ohjauskulmaa. This is commonly achieved through a steering rack and pinion mechanism or a recirculating ball system. The steering angle sensor, when present, measures the instantaneous steering wheel position and provides this information to the vehicle's control units, which can then influence other systems like electronic stability control or active steering.

Understanding ohjauskulmaa is fundamental to vehicle dynamics and control. It directly impacts the turning radius of a vehicle, its ability to navigate corners, and its overall responsiveness to driver inputs. The precise control of this angle is a key factor in safe and efficient vehicle operation.
