1. A vehicle driving system that is to be provided in a vehicle, the vehicle driving system comprising:
a touch sensor that is provided in a steering operation device of the vehicle, the touch sensor being configured to detect an electrostatic capacitance generated between the steering operation device and a driver of the vehicle; and
a control unit configured to:
receive, from the touch sensor, the electrostatic capacitance;
when the received electrostatic capacitance indicates a first electrostatic capacitance value, determine that the driver of the vehicle is in a steering-holding state in which the driver is holding the steering operation device;
when the received electrostatic capacitance indicates a second electrostatic capacitance value, determine that the driver is in a non-steering-holding state in which the driver is not holding the steering operation device; and
when the received electrostatic capacitance indicates a first fluctuation, determine that a malfunction occurred in the touch sensor,
wherein, when the control unit receives, after the control unit detects the first fluctuation in the electrostatic capacitance indicating the malfunction of the touch sensor, the first electrostatic capacitance value indicating the steering-holding state of the driver, the control unit determines that the driver is in the non-steering-holding state.
