Safe driving assistance system

A safe driving assistance system, comprising:

• a wearable device including terminal identification information;
• a first sensor including at least one selected from a group consisting of a pulse meter, a thermometer, and a diaphoremeter;
• a second sensor including an interstitial fluid glucose concentration meter;
• and
• a safe driving assistance in-vehicle device including a criteria determination unit configured to compare permissible information for the driver against at least one of:
• first biometric information received from the first sensor and second biometric information received from the second sensor to determine whether a driver is in condition to drive a vehicle, wherein:
• the permissible information comprises a minimum blood glucose level value and at least one of:
• a maximum heart rate value, a maximum skin temperature change value, and a maximum increase in sweat rate value,
• the permissible information is preset based on a medical examination result of the driver,
• the first biometric information and the second biometric information are acquired by the first and second sensors from the driver,
• the permissible information is input from a terminal and configured to be rewritable only by a specialist,
• the permissible information is stored in:
• a server located outside the vehicle, the server being capable of communicating with the safe driving assistance in-vehicle device, or
• a storage memory unit in the wearable device that is accessible only from the terminal,
• the first biometric information includes one or more of:
• a heart rate, a skin temperature change, and a sweat rate change,
• the second biometric information includes a blood glucose level,
• the criteria determination unit is configured to determine whether:
• the blood glucose level measured by the interstitial fluid glucose concentration meter is equal to or greater than the maximum blood glucose level value, and
• at least one of:
• whether the heart rate measured by the pulse meter is less than the maximum heart rate value, whether the skin temperature change measured by the thermometer is less than the maximum skin temperature change value, and the increase in sweat rate measured by the diaphoremeter is less than the maximum increase in sweat rate value,
• the safe driving assistance in-vehicle device is connected to a vehicle control unit of the vehicle driven by the driver, and
• the safe driving assistance in-vehicle device is configured to cause the vehicle control unit to control the vehicle based on a determination made by the criteria determination unit with respect to whether the driver is in condition to drive the vehicle.
