Vehicle system, a vehicle and a method for autonomous road irregularity avoidance

摘要

A vehicle, a vehicle system and a method for allowing a host vehicle to autonomously avoid road irregularities are provided. The system communicates vehicle sensor data relating to detected road irregularities and host vehicle position information with an external database. A processor is arranged to determine a trajectory for the host vehicle for which all wheels of the host vehicle are laterally displaced from one or more road irregularities ahead of the host vehicle, and to autonomously steer the host vehicle along the determined trajectory. The system is also arranged to evaluate whether all wheels of the host vehicle were laterally displaced from all detected road irregularities and to send the result of the evaluation to the external database.

1. A vehicle system for autonomous road irregularity avoidance comprising:
vehicle sensors arranged to detect irregularities on a road travelled by a host vehicle; position determination means arranged to continuously determine the host vehicle position; communication means arranged to send vehicle sensor data relating to detected road irregularities and host vehicle position information to an external database for compiling road irregularity position information; processing means comprising steering control logic; a vehicle steering system arranged to affect at least one host vehicle wheel, for enabling steering of the host vehicle; wherein the communication means are arranged to receive, from the external database, information relating to road irregularity positions on the road ahead of the host vehicle, the processing means are arranged to determine a trajectory for the host vehicle for which all wheels of the host vehicle are laterally displaced from one or more road irregularities ahead of the host vehicle, the vehicle steering system is further arranged to autonomously steer the host vehicle along the determined trajectory, the processing means are further arranged to evaluate whether all wheels of the host vehicle were laterally displaced from all detected road irregularities for a predefined road section of a used trajectory, and the communication means are further arranged to send the result of the evaluation to the external database.
