Hydropneumatic suspension for stability, accessibility and low operating costs

Buses operate under varying conditions, including fluctuating passenger numbers throughout the day, frequent stops for passengers to board and alight, uneven urban road surfaces, and increasing axle loads due to electrification. HPS is a hydropneumatic suspension system that provides stable vehicle handling, passenger and driver comfort, and integrated level control. It is highly versatile and suitable for a wide range of bus applications, including hybrid and fully electric platforms.

Why HPS for buses?

Roll stability with a high centre of gravity
HPS helps control the movement of the vehicle’s roll and improves the dynamic behaviour of electric bus platforms with a high centre of gravity.

Integrated kneeling function for accessibility
HPS supports the electronic control of levels and the kneeling function, both of which are essential for accessible low-floor bus platforms.

Passenger and driver comfort on urban road surfaces
HPS is more effective than conventional air suspension at absorbing load fluctuations, thereby improving comfort for drivers and passengers.

Integration, efficiency and compliance

Compact integration, greater design freedom for low-floor platforms
HPS’s compact system architecture increases the flexibility of designs for low-floor, electric and specialist bus platforms.

Low total cost of ownership
Thanks to its high hydraulic efficiency and low-maintenance system architecture, energy consumption, downtime and operating costs are reduced.

Complies with ISO 26262 and ISO 21434
HPS complies with the latest functional safety and cybersecurity standards, as well as current type-approval and tender requirements.
