System device for proactive risk reduction for heavy commercial vehicles

Abstract

System device for proactive risk reduction for heavy commercial vehicles, comprising at least one vehicle-side processing unit, at least one sensor system for recording vehicle-internal and environment-related condition data, a V2X communication unit for wireless communication with external road users and infrastructure facilities, and a risk assessment unit, wherein the system device is designed to determine a current risk status of the heavy commercial vehicle based on the captured sensor data and received V2X data, characterized by that the risk assessment unit generates a forward-looking risk reduction decision on the hardware or firmware side, which influences vehicle-side safety functions.

Description

Technical field

[0001] The invention relates to the technical field of vehicle-side safety and assistance systems for heavy commercial vehicles. In particular, the invention relates to a system device that combines vehicle-internal sensor data with external information received via V2X communication in order to perform predictive risk assessments and to influence vehicle-side safety functions. State of the art

[0002] Heavy goods vehicles are exposed to particular risks in road traffic due to their mass, dimensions, and braking distances. Common driver assistance systems primarily record internal vehicle data or react to immediately detected hazardous situations. Such systems often operate reactively and only consider external traffic information to a limited extent, or not at all.

[0003] Furthermore, existing solutions often rely on a continuous external network connection or perform risk assessments exclusively via software, which limits operational reliability and availability in real-world driving conditions.

[0004] The current state of the art therefore does not offer an integrated system device that assesses risks on the vehicle side in a proactive and robust manner against connection interruptions and directly affects safety-relevant vehicle functions. Object of the invention

[0005] The object of the present invention is to provide a system device for heavy commercial vehicles which: • Vehicle-internal and environment-related condition data is recorded, • Integrated external traffic information via V2X communication, • determines a current and future risk status of the vehicle, • generates proactive risk mitigation decisions, • directly affects vehicle-side safety or assistance systems, and • remains functional even without a permanent external network connection. Summary of the invention

[0006] The problem is solved by a system device for predictive risk reduction for heavy commercial vehicles with the features of the claims.

[0007] The system device comprises at least one vehicle-side processing unit, a sensor system for recording vehicle-internal and environment-related condition data, a V2X communication unit for wireless communication with external road users and infrastructure facilities, and a risk assessment unit.

[0008] The risk assessment unit generates a predictive risk mitigation decision at the hardware or firmware level, which influences vehicle safety functions. This enables an early and technically controlled reduction of accident or hazard risks. Detailed description of the invention

[0009] The system device according to the invention is arranged or can be integrated into a heavy commercial vehicle.

[0010] A vehicle-side processing unit coordinates the acquisition, processing, and evaluation of status data. The sensor system records internal vehicle status data, such as speed, acceleration, braking status, and vehicle dynamics, as well as environmental data, such as distances, road surface conditions, and weather influences.

[0011] The system device wirelessly receives status, warning, or traffic data from other vehicles, traffic infrastructure, or road sensors via a V2X communication unit. This information is then fed to the risk assessment unit.

[0012] The risk assessment unit determines the current risk state of the heavy commercial vehicle based on sensor data and received V2X data. In a preferred embodiment, the risk assessment unit combines historical condition data with current sensor data and V2X information to predict a future risk state.

[0013] Based on this assessment, the risk assessment unit generates a proactive risk mitigation decision that is linked to at least one in-vehicle safety or assistance system. These include, in particular, braking systems, drive systems, steering assistance systems, and warning and display units.

[0014] The system is designed so that risk assessment and risk mitigation decisions can be performed on the vehicle side, independent of a permanent external network connection. This ensures robust operation even with limited connectivity.
