Method for dividing front windshield of commercial vehicle into zone A and zone B

Abstract

The invention discloses a method for dividing a front windshield of a commercial vehicle into a zone A and a zone B. Firstly, plane dividing base points (V1 and V2) are obtained through the utilization of a design reference point (R) and a backrest included angle (alpha) of a vehicle chair. Then, multiple segmentation planes are formed based on the plane dividing base points (V1 and V2), and the front windshield (1) is divided into the zone A and the zone B according to intersecting lines formed by the multiple segmentation planes and the surface of the front windshield (1). In the method for dividing the front windshield of the commercial vehicle into the zone A and the zone B, the difference between the chair heights and the backrest included angles of the commercial vehicle and a common passenger vehicle is considered, the plane dividing base points are obtained with reference to the design reference point (R) and the backrest included angle (alpha) of the vehicle chair, the multiple segmentation planes (P1, P2, P3 and P4) are then obtained through the plane dividing base points, and the zone A and the zone B are divided on the front windshield, so that proper sizes of zone A and zone B which are suitable for the position and the visual field of a driver are obtained.

Description

technical field [0001] The invention relates to a method for dividing zone A and zone B of a front windshield of a vehicle, in particular to a method for dividing zone A and zone B of a windshield of a commercial vehicle such as a truck. Background technique [0002] At present, the AB area division of the front windshield field of view of domestic commercial vehicles is usually divided by referring to the method of M1 vehicles. However, due to the different occupant sitting postures of the passenger body and the commercial vehicle (especially flat-top commercial vehicles), the field of vision in the AB area of ​​the front windshield divided by the passenger-type standard cannot fully meet the corresponding visual field requirements of flat-top commercial vehicles. , i.e. the area extent is not large enough and the position relative to the occupant is not correct. This may cause the AB area of ​​the wiper to fail to achieve the expected brushing effect, so that the wiper ca...

Problems solved by technology

However, due to the different occupant sitting postures of the passenger body and the commercial vehicle (especially flat-top commercial vehicles), the field of vision in the AB area of ​​the front windshield divided by the passenger-type standard cannot fully meet the corresponding visual field requirements of flat-top commercial vehicles. , that is, the area is not large enough to be positioned correctly relative to the occupant

This may cause the AB area of ​​the wiper to fail to achieve the expected brushing effect, so that the wiper cannot remove the rain, snow, stains, etc. on the windshield well, which may affect the driver's direct vision or even indirect Vision, so that the driver's vision may have a certain blind spot
