Unintentional deactivation of an ADF by the user is an event that needs to be avoided at all costs. The driver may be concentrating on a non-driving task and will not be ready to take back the control of the driving task immediately. Similarly, it is important to prevent unintentional activations of the ADF by the user. Unexpected longitudinal or lateral inputs from the ADF may have a detrimental effect on the user’s trust in the ADF and even on the vehicle guidance as whole, thus being safety critical. There are many possible concepts for activating and deactivating the ADF, but the safety of the transition of control should not be overlooked when designing this part of the HVI (Ercan et al., 2017).
Main Question:
Are unintentional activations and deactivations of the ADF prevented?
Sub-Questions:
- Are the ADF controls designed so as to reduce accidental activation / deactivation?
- Is the ADF able to determine accidental activations / deactivations vs intentional ones?
- Is a fall-back considered for the case where an accidental deactivation occurs and the driver is not in the loop?
