“…Entry strategies are generally divided into foot first or hip first movements (Ait al Menceur et al, 2008). To provide more detailed information entry strategies were classified into one of the four categories defined by Rigel (2005) and described in Table 1.…”

“…This is greater than the percentages reported in comparable research. Ait al Menceur et al (2008) classified the slip strategy as one-foot ingress movement with lateral sliding. In their study 51% of the participants adopted this strategy.…”

“…It is known that people enter cars using a number of strategies but that individuals display stability of strategy within a vehicle (Ait al Menceur et al, 2008;Johansson 2002;Rigel, 2005) and could change their strategy when entering a vehicle with a different geometry (Ait al Menceur et al, 2008;Cherednichenko et al, 2006). This stability of strategy would therefore be expected across a real car and a valid model of that car; i.e.…”

“…As the design develops, the quality and fidelity of the buck increases, followed by the production of a prototype vehicle, at which point the entry and exit condition can be validated with confidence. This traditional process is heavily reliant on physical properties that are expensive and time consuming to produce (Ait El Menceur et al, 2008;Laughery, 2005;Sӧdermann 2005). In addition, traditional user trials with significant sized groups of people are cost and time intensive (Pudlo et al 2006).…”

AbstractEase of entry and exit is important for creating a positive first impression of a car and to increase customer satisfaction. Several methods are used within vehicle development to optimise ease of entry and exit, including CAD reviews, benchmarking and buck trials.However, there is an industry trend towards digital methods to reduce the costs and time associated with developing physical prototypes. This paper reports on a study of entry strategy in three properties (buck, car, CAVE) in which inconsistencies were demonstrated by people entering a vehicle representation in the CAVE. In a second study industry practitioners rated the CAVE as worse than physical methods for identifying entry and exit issues, and having lower perceived validity and reliability. However, the resource issues associated with building bucks were recognised. Recommendations are made for developing the CAVE and for combinations of methods for use at different stages of a vehicle's development. Keywords: entry exit, automotive Highlights: Inconsistent entry strategies were observed in a CAVE virtual environment  The CAVE needs development to support design for ease of entry and exit  Representation of vehicular hard points is necessary for optimising entry and exit  Various combinations of methods are required at different stages of vehicle development 2

“…Results from the study found that seat and door heights had significant effects on egress kinematics, while seat position had no effect. More recently, Ait El Menceur et al (2008) examined alternative techniques and movements used in entering and exiting four types of vehicles (small car, medium car, minivan, and small utility) by young ablebodied participants (n=8; age=26±5), elderly able-bodied participants (n=19; age=71±5), and participants with prostheses (n=14; age=62±13). Five ingress techniques (three one-foot movements, 2 two-foot movements) and three egress techniques (two one-foot movements, one two-foot movement) were identified.…”

Crew modules use recumbent seats to sustain increased acceleration in the upright direction. Entry (ingress) and exit (egress) of such seats require different techniques. Most of the existing research on ingress and egress biomechanics was done using vertically mounted automobile seats. In this study, ingress and egress and planar reach motions performed using seats mounted in vertical and horizontal orientations were evaluated. An eight camera (MX-13 series) optical motion analysis system (Vicon, Nexus, UK) was used to record the 3D kinematic data. Ten healthy male participants performed ingress and egress motions using the following three seat orientations, while reach tasks were only performed in the first two: (1) vertically mounted with a 90° seat angle, (2) horizontally mounted with a 90° seat angle, and (3) horizontally mounted with a 120° seat angle. A custom full-body marker set was used for the kinematic data collection. Visual3D software (C-Motion, Inc., Germantown, MD, USA) was used to formulate a dynamic model using this marker set to compute the joint angles for the ingress/egress tasks, while the distance from the clavicle to the finger markers during the reach tasks was used to determine reach in different anatomical planes. In general, peak joint angles and ranges of motion of the upper body were much higher in the horizontal seat than the horizontal seats. Differences in the lower body were less drastic, and change in kinematics between horizontal seats was negligible. These results suggest that ingress and egress of horizontal seats require more energy and can result in more strain on the user. Therefore, when horizontal seats must be used, ingress/egress space requirements, control placement, and appropriate user training are crucial considerations.

Drivers with physical impairments may face challenges associated with vehicle access and egress as well as body positioning to optimize sitting comfort and access to vehicle controls and displays. These requirements are necessary for reliable and safe completion of various operations associated with the task of driving. Key ergonomic considerations which impact upon vehicle driver-cabin configurations are discussed and general practice guidelines are outlined.
