Since 1929, the word “Mayday”, repeated three times, is an internationally recognized distress call, meaning “help me” (derived from the French “m’aider”). This voiced distress signal replaced the SOS Morse code signal, and is used internationally on aircrafts and ships via radio communications.
Mayday patents refer to various on board emergency reporting and communication systems for automobiles and other types of water and air crafts. The Mayday patent selected here is one of many Toyota Mayday patents for automobiles.
In this particular Toyota Mayday patent, JP20003395292, titled Mayday System, the on board Mayday system is specifically designed as an anti-theft device, connected to a Mayday Center that remotely controls the stolen vehicle via radio communications. Indeed, the Mayday Center sends a signal to the Mayday system of the stolen vehicle, which then carries out instructions to alter the stolen vehicle’s gear box and speed, so that the moving capacity of the stolen vehicle is reduced ,and the stolen vehicle is “compelled to move at a slow speed”.
