Examples of DDT fallback in a sentence

  • A condition to which a user or an ADS may bring a vehicle after performing the DDT fallback in order to reduce the risk of a crash when a given trip cannot or should not be completed.

  • Secondly, the test platform to perform the DDT fall-back strategy is detailed.

  • However, a fall-back ready user, who becomes a driver during fallback, is specified as the DDT fallback.

  • The velocities are limited considering the curvatures along the route [26] defining bounds for lateral and longitudinal accelerations bearing in mind the passenger comfort [35].In case of failure, a DDT fall-back strategy starts, and the trajectory planned is modified to achieve a degraded driving mode.

  • This architecture allows the verification of the DDT fall-back strategy after the occurrence of a positioning system failure.In the next subsections, the different stages that compose the proposed architecture are detailed.

  • A virtual sensor switches on by a positioning monitor in case of total failure in the position sensor is detected, then a DDT fall-back strategy is possible performing dead reckoning with database information.

  • The failure to be studied is the possible malfunction of the GNSS position receiver (which is a vital part of the ADS), which starts degrading up to total failure and a dynamic driving task (DDT) fall-back strategy must be activated by the ADS.As an additional issue, the case is considered in which the emergency shoulder cannot be used, as another vehicle is already parked, requiring driving of a longer distance to the next permitted stop while performing dead reckoning.

  • However, if commercially-available Level 3 systems were to be deployed, a CDL endorsement specifically for Level 3 automation may be appropriate considering the human driver is required to provide the DDT fallback and must understand exactly how the system would request human intervention and what would be required to respond appropriately and safely.

  • Critical information safety information will be conveyed to passengers, first responders, and emergency services, if necessary.▪ During a system disengagement or failure, the vehicle can perform DDT fallback and achieve a minimal risk condition where necessary.

  • Our contribution is to introduce the ROD as a restriction of the ODD based on current system capabilities, so that the system can continue operating safely in the ROD or perform a DDT fallback in the case of ROD violations.


More Definitions of DDT fallback

DDT fallback means a response by the user to either perform the DDT or to achieve a minimal risk condition or a response by an ADS to achieve a minimal risk condition: (1) after the occurrence of one or more DDT performance-relevant system failures, or (2) upon an ODD exit. OICA/CLEPA proposal “DDT fallback” means a response by the user to either perform the DDT or to achieve a minimal risk condition or a response by an ADS to achieve a minimal risk condition, e.g.: (1) after the occurrence of one or more DDT performance-relevant system failures, or (2) upon an ODD exit. SAE proposal … achieve a minimal risk condition in situations that include:
Sample 1
DDT fallback means the response by the person or human driver to either perform the DDT or achieve a minimal risk condition after occurrence of a DDT performance-relevant system failure(s) or upon operational design domain exit, or the response by an automated driving system to achieve minimal risk condition, given the same circumstances.

DDT fallback means the response by a highly automated vehicle driver or ADS to either perform the DDT or achieve a minimal risk condition after occurrence of a DDT performance-relevant system failure or upon operational design domain exit.
