Embodiment Construction

[0041] Figure 1a and 1b A vehicle 10 with a driver assistance system according to an embodiment of the invention is shown schematically together with a water level 20 determined by means of the driver assistance system. The vehicle has a downwardly directed distance sensor 14 on the exterior rearview mirror 12 . Distance sensor 14 is designed as an ultrasonic sensor. The water level 20 is determined by first measuring the distance d to the water surface by the distance sensor 14 . The local wading depth can be determined together with the known installation position h of the distance sensor 14 . The lateral inclination of the vehicle 10 (roll angle θ 侧倾 ) is determined by means of an acceleration sensor (not shown). A straight line 24 can be determined together with the measured distance d from the exterior mirror 12 to the water surface. Furthermore, the current water level 20 is determined via the pitch angle of the vehicle 10 .

Abstract

A driver assistance system, for determining a fording situation of a vehicle (10), includes: exactly one distance sensor for determining an instantaneous distance from an installation position of thedistance sensor to a water surface, and in particular for determining an instantaneous fording depth of the vehicle (10); a first measuring device for determining an instantaneous roll angle (theta roll) of the vehicle; a second measuring device for determining an instantaneous pitch angle (theta pitch) of the vehicle; and a calculating unit, which is coupled to the distance sensor, the first measuring device, and the second measuring device, and is configured to determine an instantaneous water surface plane (20) based on the instantaneous distance (d), the instantaneous roll angle (theta roll), and the instantaneous pitch angle of the vehicle (theta pitch). The invention also relates to a vehicle having such driver assistance system, a method for determining the wading situation of a vehicle, and a computer program product.

Description

technical field [0001] The invention relates to a driver assistance system and a method for determining a wading situation, as well as a vehicle having the inventive driver assistance system, wherein the current wading depth of the vehicle is determined. Background technique [0002] Common passenger vehicles in the wild, such as off-road vehicles or so-called SUVs ("Sport Utility Vehicles"), are designed for crossing bodies of water. When the vehicle has to be submerged in water to a certain extent, this process is referred to as a "wading process (Wat-Vorgang)". This maneuver requires great care and caution from the driver, as the driver usually does not know how deep the body of water he wishes to traverse is nor what the condition of the terrain below the surface of the water is. This problem is further exacerbated by unfavorable environmental conditions such as darkness, fog, rain or dirty water. The driver is conventionally advised to leave the vehicle before crossin...
