Description

The invention relates to a method for reducing pollutant emissions and/or increasing the range of a vehicle, as well as a system for carrying out such a method. Methods and systems for reducing emissions and/or increasing a vehicle's range are known from the prior art, and these display optimal operating parameters for the driver. These operating parameters are determined by the vehicle itself based on various data collected by its sensors. Such data can include, for example, sensor data from an Advanced Driver Assistance System (ADAS), which may include cameras, ultrasonic sensors, radar sensors, laser sensors, and other sensors, as well as relevant data concerning the driver's driving behavior. The known methods and systems use only data acquired by the vehicle itself to determine optimal operating parameters, taking into account only the vehicle's immediate surroundings. This has the disadvantage that data from outside the vehicle's immediate environment, or data not directly related to the vehicle, are not used or cannot be used to determine the operating parameters. Relevant information or data from outside the vehicle for determining operating parameters would include, for example, traffic light sequences, the type and number of other road users, and/or road characteristics. DE 10 2017 203 015 A1 This document describes a method for utilizing individual emission information from several motor vehicles in a vehicle fleet, wherein the method includes generating emission information by each of the several motor vehicles in the vehicle fleet, transmitting the generated emission information to a central, location-independent computer network system, and evaluating the generated emission information to provide fleet emission information for the vehicle fleet by the central, location-independent computer network system. The object of the present invention is therefore to provide a method and a system by which the described disadvantages of the prior art can be overcome. This problem is solved by a method according to claim 1 and a system according to claim 10. A key aspect of the invention is a method according to claim 1 for reducing pollutant emissions and/or increasing the range of a vehicle, comprising the following method steps: a) Determining initial vehicle data using a first sensor of an infrastructure system and/or a second sensor of the vehicle; b) Obtaining infrastructure data using the first sensor and/or a third sensor of the infrastructure system; c) Determining vehicle operating parameters using the infrastructure system, based on the initial vehicle data and the infrastructure data, and transmitting the operating parameters to the vehicle via the infrastructure system using an initial communication link, whereby the vehicle uses the operating parameters to reduce emissions and/or increase its range. According to the invention, a second communication link is provided between the vehicle and at least one other road user, wherein the first vehicle data is transmitted from the vehicle to the at least one other road user via the second communication link if the first communication link between the vehicle and the infrastructure system cannot be established or is not established. In this way, it is ensured that the first vehicle data can be sent to the infrastructure system even if the vehicle cannot establish a connection to the infrastructure system via the first communication link, and that operating parameters for the vehicle can be determined. For the purposes of this invention, a vehicle is to be understood as any motor vehicle which is preferably powered by an internal combustion engine, electric motor and/or fuel cell. For the purposes of this invention, a reduction in pollutant emissions is understood to mean a decrease in the amount of pollutants released during the operation of the vehicle. Pollutants within the meaning of the invention can include, for example, carbon monoxide (CO), carbon dioxide (CO₂ ) , various nitrogen oxides (NOₓ ) , sulfur dioxide ( SO₂) , ammonia ( NH₃ ), nitrous oxide ( N₂O ), soot, and/or particulate matter. An increase in range within the meaning of the invention is understood to mean an increase in the distance that can be covered with one tank of fuel or one load of the vehicle (in terms of the number of kilometers). An infrastructure system, as defined here, is a system that enables the provision of various information or data relating to traffic infrastructure and traffic. The infrastructure system can acquire this information or data itself, preferably in real time, or utilize existing data from other systems, such as urban traffic management systems. Preferably, the infrastructure system comprises a single large system or consists of a multitude of smaller systems that are interconnected. The infrastructure system includes various suitable sensors for acquiring infrastructure data and/or has access to infrastructure data from other systems. It preferably
