Vehicle steering system

A vehicle steering system, comprising:

• a steering operation member configured to receive a steering operation of a vehicle by a driver;
• a capacitive sensor provided in the steering operation member and configured such that capacitance of the capacitive sensor changes as the driver grips the steering operation member;
• a controller configured to determine that the driver is gripping the steering operation member in a case where the capacitance of the capacitive sensor is equal to or more than a first threshold and determine that the driver is not gripping the steering operation member in a case where the capacitance of the capacitive sensor is less than the first threshold;
• and
• a notification device configured to give a notification to the driver in a case where the controller determines that the driver is not gripping the steering operation member,
• wherein the controller is configured to:
• determine whether the capacitance of the capacitive sensor increases to the first threshold or more;
• determine whether the capacitance of the capacitive sensor decreases in a case where the capacitance of the capacitive sensor increases to the first threshold or more;
• determine whether the capacitance of the capacitive sensor remains at the first threshold or more in a case where the capacitance of the capacitive sensor decreases;
• and
• cause the notification device to give the notification to the driver in a case where the capacitance of the capacitive sensor remains at the first threshold or more.
