Abstract
A computer system comprising processing circuitry configured to determine that a gas leakage is present in a vehicle tire in response to a difference between a first value indicative of a gas amount in the vehicle tire at a first point in time, and second value indicative of a gas amount in the vehicle tire at a second point in time being above a predetermined threshold limit, and transmit data to perform a responsive action in response to the determined gas leakage.
Claims12
A computer system comprising processing circuitry configured to:
- receive sensor data of a first gas pressure level and a first gas temperature level of a gas in a vehicle tire at a first point in time;
- calculate a first value indicative of a gas amount contained in the tire at the first point in time, the first value being calculated in response to the first gas pressure level and the first gas temperature level;
- receive sensor data of a second gas pressure level and a second gas temperature level of the gas in the vehicle tire at a second point in time, the second point in time being subsequent to the first point in time;
- calculate a second value indicative of a gas amount contained in the tire at the second point in time, the second value being calculated in response to the second gas pressure level and the second gas temperature level;
- determine that a gas leakage is present in the vehicle tire in response to a difference between the first and second values being above a predetermined threshold limit;
- and
- transmit data to perform a responsive action in the form of transmitting an alarm message to a display arranged inside a vehicle provided with the vehicle tire in response to the determined gas leakage, wherein the alarm message causes the display to indicate a maintenance event to the operator of the vehicle in response to the difference between the first and second values being within a first predetermined range above the predetermined threshold limit, and wherein the alarm message causes the display to indicate a vehicle stop event to the operator of the vehicle in response to the difference between the first and second values being above the first predetermined range above the predetermined threshold limit.
