Challenge 24

Challenge purpose: New crash floor solutions for buses


About the challenge:

Increased safety citybus

Current city bus structures offer very little protection to the driver in case of a head-on collision with other road vehicles. Nearly all accident result in heavy injuries or the death of the driver. ​ Provisions for these impacts such as crumpling zones are not required by applicable regulations (cat. M3 vehicle class I).​ It is Ebusco’s goal to contribute to a better living environment by enabling reliable, sustainable, emission-free and affordable public transport.​ By using material in the floor in front of the wheels more effectively to absorb/deflect the impact energy the driver will have a safer working environment. The goal is to be able to offer additional safety features on the floor at no additional weight nor production cost.

Main section of application:

  • Automotive

  • Could be replicable in other sectors

Main cross-cutting topics:

  • Characterisation & modelling

  • Design & smart functions​

  • Manufacturing & assembly

Scope of the challenge

  • As there are no requirements for crash safety for vehicles (cat. M3 class I) to which a crash-safe floor needs to comply are not defined.


Design options for:

  • Improved crash behaviour within current weight & cost

  • Improved crash behaviour at the added weight and/or cost


Challenge objectives

  • Weight & cost-neutral redesign of front floor section which allows improved crash behaviour. ​

  • Design additional crash features for improved safety.​

  • Manufacture modular floor section for one or both options
