Author's note: This paper describes the research undertaken into the design of domestic vehicles and was commissioned by General Motors. General Motors were designing a vehicle with a rear hinged rear door – the vehicle would ultimately be sold under the designation of the Vauxhall Meriva. General Motors wanted to know the loads in the back and joint angle articulations during ingress and egress of occupants, together with placing heavy objects on the rear seat. The results from the base vehicle with conventional doors were then compared with the proposed design. The biomechanical analysis software developed at Coventry University was suitable for this task however it was necessary to measure the movement of the subjects within the vehicle during the activity. Optical motion tracking had not previously been successfully used within the confines of a passenger vehicle. Hence this study developed novel techniques to enable the use of existing, commercially available equipment within a hostile environment together with software which provided an interface between the measurement hardware and the analysis software.
    As a result of this study, Shanghai Automotive commissioned similar research to compare the performance of a proposed vehicle design with those of their competitors’ vehicles. The output from this study directly influenced the design of future domestic vehicle types produced by the organisation.
