Abstract

The invention relates to a method for determining the position of a vehicle (1) relative to a road (10) of a vehicle path, comprising the steps of continuously estimating (S1) the relationship between at least one side portion of said vehicle and said vehicle path distances between topographical features (30, 32; 130, 132; 230, 232) close to said side portions; and determining (S2) the lateral position of the vehicle on the basis of the thus determined distances. The invention also relates to a system for determining the position of a vehicle relative to a roadway of the vehicle's path. The invention also relates to a computer program and a computer program product.

Description

technical field [0001] The invention relates to a method for determining the position of a vehicle. The invention also relates to a system for determining the position of a vehicle. The invention also relates to a motor vehicle. The invention also relates to computer programs and computer program products. Background technique [0002] Some vehicles are equipped with cameras and / or other sensors arranged to detect lane markings on the road in the vehicle's path, either in front of the vehicle or behind the vehicle, to determine which lane the vehicle is on on the road. In a lane and where in said lane. Thus, this signal can be used to issue a warning if a vehicle inadvertently leaves a lane and / or to control a vehicle within the lane. [0003] These sensors may experience various problems in detecting road signs temporarily or over extended periods of time due to wear of the road signs, absence of road signs, or winter road conditions. Contents of the invention [000...
