ESP - Electronic Stability Program

Volvo Buses introduced ESP in 2004. Today more than half of the tourist coaches and intercity buses delivered by Volvo are equipped with this stability-enhancing program.

ESP reduces the risk of the driver losing control over his vehicle in critical situations, for example in sharp curves or on slippery surfaces.

Different sensors in the system monitor the behaviour of the coach and interacts with individual wheel braking and even reduction of engine power, if necessary.

Risk situations:
- Obstacle avoidance maneuvers with sudden steering input - risk of skidding (e.g. steering from the shoulder back on the road, avoiding animal or vehicle)
- Overestimating curve speed limit - risk of rolling over (e.g. closing curves, highway exits)
