Embodiment Construction

[0036] figure 1 A vehicle 10 is shown with a device for determining distance information. The device includes a light source 11 which is designed to illuminate objects 17 in the surroundings of vehicle 10 . Light source 11 can comprise, for example, daytime running lights, dipped beams, flashing lights, rear lights, high beams, fog headlights or reversing lights of vehicle 10 . Furthermore, the light source can comprise one or more light-emitting diodes, which generate light for illuminating the surroundings of vehicle 10 or signal light, such as light from flashing lights or brake lights. Furthermore, the light source 11 can also comprise lighting for illuminating the interior of the vehicle 10 , such as dashboard lighting or passenger compartment lighting. The device for determining distance information also includes an optical sensor 12 for receiving light reflected by an object 17 , and a processing unit 13 , which is coupled to light source 11 and sensor 12 . when in ...

Abstract

The invention relates to a method for a vehicle (10) for determining distance information for a vehicle (10). In the method, the operating state of the vehicle (10) is detected and a modulated signal is generated as a function of the operating state. A lighting device (11) of the vehicle (10) is controlled as a function of the modulated signal in order to illuminate a scene in the surroundings of the vehicle (10) or within the vehicle (10). Light rays (16) emitted by the lighting device (11) and reflected by objects (17) in the scene are received and a received signal is generated dependent on the received light rays (16). Distance information such as the distance between the object (17) and the vehicle (10) is determined as a function of the modulated signal and the received signal.

Description

technical field [0001] The invention relates to a method for a vehicle, in particular a method for determining a distance to an object in the surroundings of the vehicle, and a corresponding device. Background technique [0002] Many so-called driver assistance systems are used in modern vehicles, such as passenger cars or trucks, in order to support the driver of the vehicle when driving the vehicle. Such driver assistance systems can, for example, contribute to avoiding accidents and reduce the burden on the driver, thereby making it possible to increase comfort for the driver. Adaptive speed regulation means, for example, can automatically maintain a suitable distance to preceding vehicles. Parking aids support the driver when parking into and out of parking spaces. Further assistance systems can, for example, monitor blind spots and, depending on the traffic situation, carry out emergency braking or control interventions. Object detection systems are therefore require...
