Measuring stopping distance of a working machine with an apparatus

An apparatus for measuring stopping distance of a working machine comprising

• a user interface;
• at least one processor;
• and
• at least one memory including a computer program code, the at least one memory and the computer code configured to, with the at least one processor, cause the apparatus at least to:
• receive a first and second speed parameter based on at least two user inputs on the user interface;
• receive at least one speed information value from a controller or an engine control unit of the working machine;
• send a slowdown command to the controller or the engine control unit to decelerate the working machine when the received speed information value of the working machine is equal to the first speed parameter;
• send a stopping command to the controller or the engine control unit to stop the working machine when the received speed information value of the working machine is equal to the second speed parameter;
• track speed and time to calculate a travelled distance;
• and
• calculate the stopping distance of the working machine, wherein the stopping distance is a travelled distance travelled during the slowdown and stop time.
