Vehicular illumination system, vehicular system, vehicle, and data communication system

A vehicle that is capable of running in an autonomous drive mode, the vehicle comprising:

• a data generation unit which is configured to generate data;
• a first password generation unit which is configured to generate a password to be used for encrypting the data;
• an encryption unit which is configured to generate encrypted data by encrypting the data using the password;
• an illumination control signal generation unit which is configured to generate an illumination control signal based on the password;
• a first wireless communication unit which is configured to transmit the encrypted data wirelessly;
• an illumination unit which is configured to emit light toward an outside of the vehicle and comprises a plurality of light emission segments;
• and
• an illumination control unit which is configured to set an illumination pattern of the illumination unit based on the illumination control signal.

A data communication device comprising:

• a second wireless communication unit which is configured to receive encrypted data wirelessly;
• an imaging unit which is configured to acquire a shot image by shooting an image of an illumination pattern formed by an illumination unit of another vehicle;
• a second password generation unit which generates a password based on the acquired shot image;
• and
• a decryption unit which is configured to decrypt the encrypted data using the generated password.
