The invention relates to an arrangement (1) for a driver assistance system (100) of a vehicle (2), comprising a radiation source (7) for emitting infrared radiation, a radiation receiver (8) for receiving infrared radiation, and a windshield (5) comprising an outer glazing (9) having an outer side surface (I) and an inner side surface (II) and an inner glazing (10) having an outer side surface (III) and an inner side surface (IV), the invention relates to a windscreen (5) which is connected to one another via a thermoplastic intermediate layer (11) and which has a functional layer (12) that reflects infrared radiation. The radiation source (7), the functional layer (12) and the radiation receiver (8) are arranged in such a way that infrared radiation (13) emitted by the radiation source (7) can be reflected by the functional layer (12) onto the face (23) of the driver (3) as first reflected radiation (14), which can be reflected by the face (23) of the driver (3) onto the functional layer (12) as second reflected radiation (15), the second reflected radiation (15) reflected by the functional layer (12) as the third reflected radiation (16) can be reflected to the radiation receiver (8) and received by the radiation receiver (8). The functional layer (12) consists of an alternating layer sequence of high refractive layers (24) having a refractive index of at least 1.9 and low refractive layers (25) having a refractive index of at most 1.6, the alternating layer sequence starting with the high refractive layers (24) and ending with the high refractive layers (24).

    本发明涉及用于车辆(2)的驾驶员辅助系统(100)的布置(1),其包括用于发射红外辐射的辐射源(7)、用于接收红外辐射的辐射接收器(8),和包括具有外侧表面(I)与内侧表面(II)的外层装配玻璃(9)和具有外侧表面(III)与内侧表面(IV)的内层装配玻璃(10)的挡风玻璃(5),其经由热塑性中间层(11)彼此连接,挡风玻璃(5)具有反射红外辐射的功能层(12)。如此布置辐射源(7)、功能层(12)和辐射接收器(8),使得由辐射源(7)发射的红外辐射(13)可以被功能层12反射到驾驶员(3)的面部(23)上作为第一反射辐射(14),该第一反射辐射(14)可以被驾驶员(3)的面部(23)反射到功能层(12)上作为第二反射辐射(15),并且作为第三反射辐射(16)的被功能层(12)反射的第二反射辐射(15)可以被反射至辐射接收器(8)并由辐射接收器(8)接收。功能层(12)由具有至少1.9的折射率的高折射层(24)和具有至多1.6的折射率的低折射层(25)的交替层序列组成,其中交替层序列以高折射层(24)开始,并以高折射层(24)结束。
