A travel control method for a vehicle detects a target trajectory along which a subject vehicle should travel and controls the subject vehicle to travel in an autonomous manner along the detected target trajectory. This method includes provisionally setting a forward gaze point distance from the subject vehicle to a forward gaze point, estimating a traveling trajectory in which the subject vehicle coincides with the target trajectory at the forward gaze point, detecting a maximum value of a lateral displacement between the estimated traveling trajectory and the target trajectory during travel from a current position of the subject vehicle to the forward gaze point, and definitely setting the forward gaze point distance when the maximum value of the lateral displacement is a predetermined value or less as an actual forward gaze point distance and controlling the subject vehicle to travel on the basis of the definitely-set forward gaze point distance.

Processing of sensor data for a driver assistance system

In order to process sensor data for a driver assistance system oriented towards the driver's comfort, sensor data that is sensed by a sensor device and describes objects is preprocessed such that a distinction is made between a driving zone and a non-driving zone, where the driving zone is designated as an object driving zone. The object driving zone is delimited by a boundary line. Since the sensor data is processed for a comfort-oriented driver assistance system, it does not have to describe the entire theoretical driving zone. Rather, the boundary line is used to delimit the driving zone within which the vehicle can normally be expected to drive. Based thereon, it is easy to determine an appropriate boundary line and significantly reduce the volume of data to be transmitted from the sensor device to a central control device of the comfort-oriented driver assistance system in order to describe the sensed objects.
