This paper presents the development of the Mobility Lab, an instrumented car that
was developed to support research on the comfort of automated driving. The Mobility Lab
was established as a platform to investigate the implications of motion sickness on
human users especially when exposed to low-frequency horizontal forces while engaging in
non-driving activities. First, the Mobility Lab's overview of interior setup and system
architecture involving data acquisition system with its sensors is described. Then, a
validation study is presented, comprising of simulations with forty-six participants by
two designated drivers. The simulations were focusing on the manipulation of lateral
acceleration based on defensive automated driving style settings. The consistency of the
manipulations in terms of accelerations, velocities, frequencies and motion sickness
dose values by both drivers was measured and compared. Subjective motion sickness
assessments, as well as user rating towards the believability of the Mobility Lab
platform, were also carried out. The results indicate good reliability in producing
consistent simulations of automated driving experience within the desired settings. In
addition, the versatility of Mobility Lab in term of flexibility on interior setup
arrangement and also its measurement system makes various automated driving related
experiments possible.
