The present invention resides in a travel assist apparatus that performs assist of warning or support so that departure of a vehicle from a traveling lane is avoided, wherein a timing to the assist is to be performed is changed depending on a lane entering angle of an oncoming vehicle and a lane departure angle of a subject vehicle with respect to the traveling lane. Accordingly, the timing at which the assist is to be performed is changed depending on the lane entering angle of the oncoming vehicle and the lane departure angle of the subject vehicle with respect to the traveling lane. Therefore, it is possible to advance the timing at which the assist is to be performed as the possibilities is higher that the behaviors of the oncoming vehicle and the subject vehicle hinder the traveling of the subject vehicle.
A travel assist apparatus that performs assist of warning or support so that a departure of a subject vehicle from a traveling lane is avoided, the apparatus comprising:
A travel assist apparatus for assisting a driver to avoid a departure of a subject vehicle from a traveling lane, the travel assist apparatus comprising:
A travel assist method for assisting a driver to avoid a departure of a subject vehicle from a traveling lane, the travel assist method comprising:
A travel assist method for assisting a driver to avoid a departure of a subject vehicle from a traveling lane, the method comprising:

The present invention relates to a travel assist apparatus and a travel assist method.
A technique has been disclosed, wherein the drive assist control, which includes, for example, the alarm output, the forcible braking, and the avoidance steering, is executed if it is determined that another vehicle (object vehicle) may protrude to a cruising lane of a subject vehicle and there is some possibly of causing collision when the object vehicle intends to turn to a road on which the subject vehicle travels, from an intersecting road (see, for example, Patent Document 1).
PTL 1: Japanese Patent Application Laid-Open No. 2010-083314A;
FIG. 1 shows a block diagram illustrating the construction of a drive assist apparatus according to a first embodiment of the present invention while being classified into distinct functions.
FIG. 2 shows a situation in which a subject vehicle and an oncoming vehicle are present on a road according to the first embodiment.
FIG. 3 shows a relationship between (θ1+θ2) and the traveling lane boundary according to the first embodiment.
A specified embodiment of the present invention will be explained below. An explanation will now be made about a drive assist apparatus (driving support apparatus, for example, LDW, LDP or the like) which recognizes the traffic lane and the non-travelable area, which sets the traveling lane on the basis of the recognized traffic lane and the non-travelable area, and which performs the drive assist process in order to avoid the departure of a subject vehicle from the traveling lane. The drive assist process referred to herein is executed earlier than the collision damage mitigating process which is executed when the vehicle is subjected to the emergency stop and when the collision between a vehicle and an obstacle is inevitable, wherein the assist is performed so that the traveling itself can be continued. Therefore, the drive assist apparatus of the present invention is different from a certain drive assist apparatus (for example, PCS or the like) which performs the collision damage mitigating process. The construction, which is explained in the following embodiment, represents a mode for carrying out the present invention, which does not limit the construction of the present invention.
(Drive Assist Apparatus)
FIG. 1 shows a block diagram illustrating the construction of a drive assist apparatus (driving support apparatus) according to a first embodiment of the present invention while being classified into distinct functions. As shown in FIG. 1, an electronic control unit (ECU) 1 for assisting the driving, which constructs the drive assist apparatus, is carried on a vehicle.
