1. A driving assistance system comprising:
a first control unit configured to output an output amount related to a required amount; and
a second control unit configured to calculate a difference amount between the output amount output from the first control unit and an actually measured amount of an actuator, and control the actuator based on the difference amount and a torque map,
wherein the driving assistance system is capable of selectively executing at least one of a first driving assistance control that performs a first driving assistance and a second driving assistance control that performs a second driving assistance different from the first driving assistance,
in the first driving assistance control,
the first control unit outputs a first required amount as the output amount, and
the second control unit calculates a difference amount between the first required amount and the actually measured amount, and controls the actuator based on the difference amount and a first torque map, and
in the second driving assistance control,
the first control unit calculates a difference amount between a second required amount and the actually measured amount, acquires a division amount by dividing the difference amount by a predetermined value, and outputs a total amount of the division amount and the actually measured amount as the output amount, and
the second control unit calculates a difference amount between the total amount and the actually measured amount, and controls the actuator based on the difference amount and a second torque map.
