TRAVEL CONTROL SYSTEM

An arithmetic unit (110) includes: a vehicle exterior environment recognition unit (111); a route setting unit (112 to 115); a vehicle motion determination unit (116) configured to determine a target motion to follow a set route; a driving force calculation unit (117) and a braking force calculation unit (118) which are configured to calculate target physical amounts, i.e., a target driving force and a target braking force, corresponding to the target motion; and a steering controller (129) configured to calculate another target physical amount, i.e., a target steering amount, corresponding to the target motion, directly output a control signal to a steering device, and output, to the driving force calculation unit (117) and the braking force calculation unit (118), information for use to perform control that allows the driving and braking devices to coordinate with the steering device.
