Abstract
In a travel control apparatus for a vehicle, a travel environment information acquisition unit acquires travel environment information on a travel environment of the vehicle. A travel information detector detects travel information on the vehicle in order to execute automatic driving control based on such information pieces. A lateral force generator generates lateral force to be applied to the vehicle during the automatic driving control. A torsion bar is interposed on a torque transmission path of a steering system. A steering wheel angle detector detects a steering wheel angle. A lateral force detector detects the lateral force acting on the vehicle. An intervening steering operation determination unit determines that a driver has performed an intervening steering operation when a characteristic of the detected steering wheel angle and lateral force differs from a reference characteristic that varies univocally when the steering wheel is in a no load condition.
