At higher road speeds, loss of control can lead to skidding, rollover or collision. Vehicle lateral stability is an important factor in maintaining safe motion.
Definition
Lateral stability is the ability to maintain a normal direction and state of motion under external influences, without loss of control leading to sideslip or rollover. It involves the interaction of the driver, vehicle and environment.
Role in vehicle safety
Lateral stability is important for safe high-speed travel. Stability control improves handling near the vehicle's operating limits. During fast cornering or lane changes, substantial lateral forces produce yaw motion. On slippery surfaces, sideslip can develop rapidly; once it begins, available lateral tyre-road forces can decrease and the vehicle may lose control.
Maintaining stability is therefore essential to safe steering. In an emergency, abrupt driver responses can push tyres to their adhesion limits, resulting in loss of control. Research and measurement of lateral stability support safer vehicle development.
