Publication number: 20230174115Abstract: An MRM planning system for supporting planning of a minimal risk maneuver, MRM, of an Automated Driving System. The system determines a remaining distance to an upcoming operational design domain, ODD, exit at which an ODD defined for the autonomous driving mode is planned to end. The system further assesses, when the remaining distance is shorter than a predeterminable distance, data associated with a stretch of road leading up to the ODD exit. The system identifies based on the assessment of the data, a favourable region along the stretch of road for potentially bringing the vehicle to a stop deemed safe subsequent a potential MRM being triggered. The system determines a timing at which to initiate an autonomous driving mode DDT termination procedure at which to provide a handover request prompting an occupant of the vehicle to take over the DDT.Type: ApplicationFiled: December 7, 2022Publication date: June 8, 2023Inventors: Zhennan FEI, Mattias BRÄNNSTRÖM

Publication number: 20230133341Abstract: A driving mode transitioning system and method for supporting transitioning to an unsupervised autonomous driving mode of an Automated Driving System, ADS, of a vehicle. The driving mode transitioning system obtains vehicle situational data indicating a state of vehicle surroundings along with position and heading of the vehicle; determines based on the obtained vehicle situational data, that unsupervised driving conditions of an unsupervised driving mode-related driving policy pertinent an unsupervised autonomous driving mode of the ADS, are complied with; determines that the ADS has active a supervised driving mode; implements the unsupervised driving mode-related driving policy to govern the supervised driving mode; and enables the unsupervised autonomous driving mode to be activated for the ADS, when positioning and/or velocity of the vehicle has reached compliance with unsupervised dynamic driving conditions of the unsupervised driving mode-related driving policy.Type: ApplicationFiled: October 31, 2022Publication date: May 4, 2023Inventors: Peter HARDÅ, Mattias Brännström

Publication number: 20220396281Abstract: The present invention relates to methods and systems that utilize the production vehicles to develop new perception features related to new sensor hardware as well as new algorithms for existing sensors by using self-supervised continuous training. To achieve this the production vehicle's own perception output is fused with other sensors in order to generate a bird's eye view of the road scenario over time. The bird's eye view is synchronized with buffered sensor data that was recorded when the road scenario took place and subsequently used to train a new perception model to output the bird's eye view directly.Type: ApplicationFiled: June 9, 2022Publication date: December 15, 2022Inventors: Mattias BRÄNNSTRÖM, Joakim LIN SÖRSTEDT, Jonas EKMARK, Mats NORDLUND

Patent number: 11351992Abstract: Described herein is a method and system for assisting a driver of a vehicle (1) to drive with precaution. Vehicle environment monitoring sensors (3a, 3b) determines other road users and particular features associated with a traffic situation of the vehicle (1) and hypotheses are applied related to hypothetical threats that may arise based thereupon. A driver level of attention, required to handle the hypothetical threats, and a time until that level will be required is estimated. A current driver level of attention is derived, from driver-monitoring sensors (4). If determined that the estimated required driver level of attention exceeds the current and the time until the estimated driver level of attention will be required is less than a threshold-time (tthres), there is produced at least one of visual (5), acoustic (6) and haptic (7) information to a vehicle driver environment, and/or triggered at least one of automated braking (8) and steering (9) of the vehicle (1).Type: GrantFiled: May 31, 2019Date of Patent: June 7, 2022Assignees: ZENUITY AB, VOLVO CAR CORPORATIONInventors: Mattias Brännström, Claes Olsson, Andrew Backhouse, Victor Trent

Publication number: 20210316765Abstract: A method for managing a hand-over from an Automated Driving System (ADS) to driver of vehicle, where ADS includes ADS feature being associated with first set of pre-cautionary constraints out of plurality of pre-cautionary constraints imposed by Pre-cautionary Safety (PCS) module while ADS feature controls vehicle. The method includes obtaining request to deactivate ADS feature, and providing partial control of vehicle to driver in order to enable manual driver operation of vehicle based on obtained request. The method includes monitoring manual driver operation of vehicle for a time period, and evaluating monitored manual driver operation of vehicle against second set of pre-cautionary constraints during time period. Then, based on evaluation, the method includes deactivating second set of pre-cautionary constraints upon expiry of time period if manual driver operation passes evaluation, or providing control of vehicle to ADS if manual driver operation fails evaluation.Type: ApplicationFiled: April 7, 2021Publication date: October 14, 2021Inventors: Peter HARDÅ, Mattias BRÄNNSTRÖM

Patent number: 11084486Abstract: A method performed by a vehicle system for handling conditions of a road on which a vehicle travels. The vehicle system detect that a first part of the road has a first condition which is different from a second condition of a second part of the road. The vehicle system estimates friction of the first part and evaluates the estimated friction. The vehicle system determines that the vehicle's motion should be adjusted when a result of the evaluation indicates that the estimated friction of the first part of the road affects the vehicle's expected motion, and initiates adjustment of the vehicle's motion on the road as determined.Type: GrantFiled: March 22, 2019Date of Patent: August 10, 2021Assignee: Volvo Car CorporationInventors: Jonas Nilsson, Mats Jonasson, Mattias Brännström

Publication number: 20210107499Abstract: The present disclosure relates to a method for controlling a control system of a vehicle having a first driver support module (e.g. ADAS feature) and a second driver support module (e.g. “under-development” ADS feature). The first driver support module and the second driver support module are capable of operation within an overlapping operational design domain (ODD). The method includes obtaining sensor data including information about a surrounding environment of the vehicle and determining fulfilment of the overlapping ODD based on the obtained sensor data.
