Abstract
A method and a control unit for checking an exhaust gas system in a vehicle. A control unit in the vehicle receives data from sensors of the vehicle and sends out control commands to final control elements of the vehicle. The control unit is in communication connection with an external computer located outside of the vehicle. The external computer causes the control unit to make an active intervention in the exhaust gas system by actuating final control elements of the vehicle. The control unit receives sensor data from the exhaust gas system, which it forwards to the external computer. Based on the sensor data from the sensors, the external computer rates the exhaust gas system as “OK” or “manipulated”.
Claims16
A method for checking an exhaust gas system in a vehicle, a control unit in the vehicle being configured to receive data from sensors of the vehicle and send out control commands to final control elements of the vehicle, the control unit being in communication connection with an external computer located outside of the vehicle, the method comprising the following steps:
- receiving, by the external computer, sensor data from the exhaust gas system;
- analyzing, by the external computer, the received sensor data;
- based on the analyzing by the external computer, determining by the external computer whether an active intervention in the exhaust system should take place;
- based on determining, by the external computer, that the active intervention in the exhaust system should take place, causing, by the external computer, the control unit to make an active intervention in the exhaust gas system by actuating the final control elements of the vehicle, the control unit receiving additional sensor data from the exhaust gas system after actively intervening, and forwarding the received additional sensor data to the external computer;
- and
- based on the additional sensor data from the sensors, the external computer rating the exhaust gas system as “OK” or “manipulated”.
A control unit configured to check an exhaust gas system in a vehicle, the control unit configured to:
- receive data from sensors of the vehicle and send out control commands to final control elements of the vehicle, the control unit being in the vehicle and being in communication connection with an external computer located outside of the vehicle;
- send sensor data from the exhaust gas system to an external computer, the external computer analyzing the sent sensor data and, based on the analyzing, the external computer determining whether an active intervention in the exhaust system should take place;
- receiving signals from the external computer, the external computer sending the signals to the control unit based on the external computer determining the active intervention in the exhaust system should take place;
- actively intervene in the exhaust gas system, based on the signals from the external computer, by actuating the final control elements of the vehicle;
- receive, after actively intervening, additional sensor data from the exhaust gas system;
- and
- forward the received additional sensor data to the external computer.
