Description

The invention relates to a method for operating a vehicle.The invention is based on a method for operating a vehicle, having the following steps:providing a vehicle, wherein the vehicle comprises vehicle tires;providing a state determination device, wherein the state determination device is provided for determining a technical state of the vehicle tire;determining the technical state of the vehicle tire by means of the state determination device.The vehicle tire is in particular at least one vehicle tire, and the vehicle can have a plurality of vehicle tires.The vehicle can be, for example, a passenger car vehicle, a truck vehicle, a special vehicle, an agricultural vehicle, a mining vehicle or a two-wheel vehicle.The determination of the technical state of the vehicle tire by means of the state determination device is carried out, for example, as a function of a quantifiable property of the vehicle tire that is detected or detectable by sensors. The quantifiable property is, for example, an air pressure, a profile depth or a degree of abrasion of the vehicle tire.The state determination device is, for example, a device for electronic data processing, for example a computer.In particular, the state determination device has an artificial intelligence component for determining the technical state of the vehicle tire as a function of a quantifiable property of the vehicle tire which is detected or can be detected by sensors.Methods for operating a vehicle are known from the prior art. It is also known from the prior art that the methods have the following steps:providing a vehicle, wherein the vehicle comprises a vehicle tire;providing a state determination device, wherein the state determination device is provided for determining a technical state of the vehicle tire;determining the technical state of the vehicle tire by means of the state determination device.The technical state of the vehicle tire is, for example, a quantifiable state of the vehicle tire, for example, a degree of wear or damage to the vehicle tire.The methods known from the prior art for operating a vehicle could not be designed optimally.For example, in the case where it is necessary to change this vehicle tire and to replace it with another, in particular new, vehicle tire depending on a state of the vehicle tire, a selection of a possible travel route from the spatial position of the vehicle to a location at which the other, in particular new, vehicle tire is provided for replacement could be made by a technician or user of the vehicle. For example, this technician or user could not determine the optimal route on which the vehicle can reach the location of the other, in particular new vehicle tire. A travel route may not be optimal, for example, if it has unnecessary lengths or unfavourable roadway conditions. The unfavourable roadway conditions can lead, for example, to damage to other vehicle tires of the vehicle or of the vehicle as a whole which are still usable. Furthermore, a selection of the travel route by a technician or user can be erroneous or associated with a comparatively high time expenditure.The object of the invention is therefore to provide an improved method for operating a vehicle.The object set according to the invention is achieved in that the method has the following further steps:providing an evaluation device, wherein the evaluation device is provided to determine a spare tire as a function of the technical state of the vehicle tire and as a function of technical information about the vehicle tire;determining the spare tire as a function of the technical state of the vehicle tire and as a function of the technical information about the vehicle tire by means of the evaluation device;determining a spatial position of the spare tire;determining a spatial position of the vehicle;determining a travel route from the spatial position of the vehicle to the spatial position of the spare tire by means of the evaluation device.The evaluation device is, for example, a device for electronic data processing, for example a computer, in particular a smartphone or a tablet computer.
