Influence of risk expectation on haptically cued corrective manoeuvres during near lane departure

Abstract

This paper showed that corrective manoeuvres following directional pulses on the steering wheel (motor priming) are modulated by risk expectation. The conclusion may be of interest for designers of haptics-based automation such as lane departure warning and lane keeping assistance systems.

Research on effects of pattern, amplitude and frequency of pulse steering torque warnings for lane departure

“…This is supported by previous studies that faster responses were observed when pulse cueing was stronger (Deroo et al, 2012(Deroo et al, , 2013. The pulse torque is asymmetrically superimposed on the steering wheel.…”

“…In previous studies, haptic warning devices were found to be effective on lane departure warning (Deroo, Hoc, & Mars, 2012, 2013Navarro, Mars, Forzy, El Jaafari, & Hoc, 2010;Navarro, Mars, & Hoc, 2007;Suzuki & Jansson, 2003), but the parameters of steering pulse torque were different. The following section will discuss the determinants of the effects of haptic parameters and impacts of drivers' subjective feelings on the warning effectiveness.…”

Tactile warning signals for in-vehicle systems

“…It is, however, worth pointing out that directional pulses (as in the oscillation involved in MP warning signals) may also result in the driver making reflexive counteractions by turning the steering wheel in the direction opposite to the pulse without the appropriate diagnosis of the situation, especially in time critical situations (see Ziegler, 1995;Kullack et al, 2008;Deroo et al, 2012). For example, in the study of a LDWS that also used a similar directional pulse as the MP on the steering wheel, Suzuki and Jansson (2003) found that many of their participants (approximately 50%) actually turned the steering wheel in the opposite direction in order to compensate for the steering pulses toward the center of the lane.…”

Drivers’ ability to learn eco-driving skills; effects on fuel efficient and safe driving behaviour

“…the information can be "ignored" if necessary, Mollenhauer et al, 1994), the concern that increasing amounts of visual information may compromise driver safety has led to developments in other modalities for both safety and eco driving applications. Haptic feedback (via the accelerator or brake) for collision avoidance (Lee et al, 2007), headway (Mulder et al, 2008), speed (Adell, Varhelyi and Hjalmdahl, 2008), and lane departure (Deroo, Hoc and Mars, 2012) have received attention. More recently, Birrell, Young and Weldon, (2013) evaluated the effects of a haptic accelerator pedal on driving performance and perceived workload and found positive changes to driver behaviour compared to a baseline condition.…”
