• cars in particular rented motor vehicles
• vehicles can include, for example, motor vehicles such as passenger cars and/or trucks, as well as conventional vehicles with an internal combustion engine or vehicles with an electric drive or hybrid drive.
• motor vehicles such as passenger cars and/or trucks
• conventional vehicles with an internal combustion engine or vehicles with an electric drive or hybrid drive Since an increasing demand for car-sharing vehicles can be observed, the number of users of a single vehicle is increasing.
• infectious diseases can easily be transmitted, in particular via contact, droplet and/or smear infections.
• a user of a Car-Sharing vehicle can thus more easily contract an infectious disease, especially if the previous user of this vehicle has shown or is showing symptoms of the disease.
• the risk of infection in Car-Sharing vehicles can be regarded as increased.
• the object is achieved by a system for disinfecting a vehicle, which can be used by several different users, the system comprising the following:
• an evaluation unit which is designed to evaluate the data received from the sensor unit regarding the state of health of the user by means of a target/actual value comparison and to determine a probability of an illness of the user based on the evaluation;
• a control unit which is designed to carry out an adjustment of at least one vehicle component of the vehicle and/or at least one action on the vehicle depending on the probability of the user being ill.
