Solution Overview

Problem

Existing motor vehicle systems lack an efficient and reliable method to simultaneously generate light and acoustic signals that are perceivable by both drivers and external road users, particularly in varying environmental conditions and scenarios such as start-up, maneuvering, or hazard situations, with existing solutions often being inadequate in ensuring safety and comfort.

Innovation Solution

A control device is implemented to synchronize the illumination and acoustic devices based on specific output conditions, such as get-in/get-out, maneuver, or driving state conditions, using sensor and control signals to generate coordinated light and acoustic signals that are optimized for ambient brightness and noise levels, ensuring intuitive perception by all relevant parties.
