Abstract

A drive support apparatus is disclosed, which includes a sonar sensor that transmits an ultrasonic wave to an object outside of a vehicle to obtain, based on a reflected wave thereof, object information related to a distance to the object; a controller that permits a first drive force limitation control when the distance to the object is longer than or equal to a predetermined distance, and permits at least one of a second drive force limitation control and an intervention brake control when the distance to the object is shorter than the predetermined distance, wherein a limitation level in the second drive force limitation control is higher than that in the first drive force limitation control.

Description

technical field [0001] The present invention relates to a driving support device. Background technique [0002] An obstacle detection device is known from Patent Publication No. 2007-333609. This known obstacle detection device compares a signal of a received wave of a sonar sensor amplified with a predetermined gain with a threshold value to determine the presence or absence of an obstacle. [0003] In general, sonar sensors have a shorter sensing distance than radar sensors using electromagnetic waves (eg, millimeter waves) or light waves (eg, laser light). In order to appropriately perform interventional braking control (or driving force limiting control) based on object information from the sonar sensor, it is beneficial to expand the sensing distance of the sonar sensor. However, if the sensing distance of a sonar sensor is extended, its detection area is correspondingly enlarged, which means that non-target objects that are not the detection target and would not othe...
