Embodiment Construction

[0043] Embodiments herein will now be described more fully with reference to the accompanying drawings, in which example embodiments are shown. However, the application should not be construed as limited to the embodiments set forth herein. One of ordinary skill in the art to which this application pertains will readily appreciate that disclosed features of the example embodiments may be combined. Like reference numerals refer to like elements throughout.

[0044] Well-known functions or constructions are not necessarily described in detail for brevity and / or clarity.

[0045] figure 1 A vehicle 200 is shown without any vehicle systems for automatically avoiding road irregularities.

[0046] The vehicle 200 travels automatically or semi-autonomously along a defined trajectory 201 on a road 203 . The road 203 extends in the longitudinal direction of the vehicle 200, and the road 203 is provided with road signs 204 on both sides thereof. Tracks 205 for vehicle wheels 206 ar...

Abstract

A vehicle (1), a vehicle system (2) and a method (100) for enabling a host vehicle to automatically avoid road irregularities are provided. The system (2) communicates vehicle sensor data and host vehicle position information on detected road irregularities (5) with an external database (14). the processing means (15) is arranged to determine a trajectory (3) of the host vehicle (1) that moves all wheels (7) of the host vehicle (1) laterally away from one or more road irregularities (5) in front of the host vehicle, And the host vehicle (1) is automatically steered along the determined trajectory (3). The system is also arranged to evaluate whether all wheels (7) of the host vehicle (1) are laterally displaced from all detected road irregularities (5) and to send the result of said evaluation to an external database (14).

Description

technical field [0001] Embodiments herein relate to vehicle systems for automatically avoiding road irregularities. Embodiments herein also relate to a vehicle comprising a vehicle system for automatically avoiding road irregularities, and a method for enabling the host vehicle to automatically avoid road irregularities. Background technique [0002] Driving comfort depends on many factors such as vehicle suspension, tire characteristics, road conditions, etc. A relevant factor is whether the vehicle is driving along a smooth road or into potholes and over bumps. A pothole is here understood to be a break in the road surface where part of the road construction material has broken away leaving a hole. A bump is here understood to be a discontinuity in the road surface, where a portion of the road's height forms an upwardly extending protrusion. The perceived driving comfort is increased if contact with bumps and potholes can be avoided. [0003] It is known to control the...
