Abstract: The present invention relates to methods and arrangements for safety monitoring of a safety zone under and in near vicinity around a parked autonomous vehicle before driving, wherein the method comprise acquiring sensor data from an active sensor system located on the undercarriage of the vehicle, wherein the active sensor system is arranged to transmit a signal and receive the signal reflected off objects within the safety zone and store sensor data representative of substantially all of the safety zone, repeatedly building a representation of the safety zone by acquiring sensor data from the active sensor system; iteratively aggregating the representations of the safety zone with a statistical model, and continuously analysing the aggregation of representations and determining if a sensitive object is located within the safety zone of the vehicle.

Abstract: Previous self-driving car systems can detect objects separately with either vision systems, RADAR systems or LIDAR systems. In an embodiment of the present invention, an object fusion module normalizes sensor output from vision, RADAR, and LIDAR systems into a common format. Then, the system fuses the object-level sensor data across all systems by associating all objects detected and predicting tracks for all objects. The present system improves over previous systems by using the data from all sensors combined to develop a single set of knowledge about the objects around the self-driving car, instead of each sensor operating separately.

Abstract: Disclosed is a method for assisting the parking of a vehicle. The method includes determining a vehicle position relative to an obstacle. When the relative position meets a first set of criteria, a first torque pulse is delivered to the steering wheel in the first direction to cue an operator of the vehicle to turn the steering wheel in the first direction. When the relative position meets a second set of criteria, a second torque pulse is delivered to the steering wheel in the second direction, opposite to the first direction to cue the operator to turn the steering wheel in the second direction. A system for assisting the parking of a vehicle is also disclosed.
