Vehicle control apparatus, vehicle control method, and program thereof
An ECU of a vehicle control apparatus obtains, using a frontward PVM camera, front side target object information that includes information on a target object that is located in a blind angle detection area lateral to and outside of a target object detection area of a frontward camera. The ECU specifies, based on the front side target object information, a kind and a moving state of a blind angle target object, and determines a front side obstacle area based on the kind and moving state of the blind angle target object. When the ECU determines that a target object whose kind and moving state coincide with the kind and the moving state, respectively, to which the front side obstacle area corresponds is located in the front side obstacle area, the ECU decreases a driving force to suppress a start of moving of the host vehicle.
1 . A vehicle control apparatus comprising:
a frontward monitoring device, that includes a frontward camera configured to take a picture of a frontward area that is an area in front of a host vehicle, configured to obtain information on an object located in a target object detection area, based on said picture of said frontward area taken by said frontward camera;
a specific camera device, that includes a frontward ultrawide-angle camera with an angle of view wider than an angle of view of said frontward camera, configured to obtain front side target object information including information on a blind angle target object that is an object located in a blind angle detection area that is an area lateral to and outside of said target object detection area; and
a controller configured to:
when said blind angle target object is detected based on said front side target object information,
specify a kind of said detected blind angle target object, based on said front side target object information;
specify a moving state of said detected blind angle target object, based on said front side target object information;
determine a front side obstacle area, based on said specified kind and said specified moving state; and
determine whether or not a start moving suppression condition is satisfied by determining whether or not a target object condition is satisfied, wherein said target object condition is a condition to be satisfied when a position of said detected blind angle target object is in said determined front side obstacle area; and
control a host vehicle driving force so as to make said host vehicle driving force of when it is determined that said start moving suppression condition is satisfied smaller than said host vehicle driving force of when it is determined that said start moving suppression condition is not satisfied.
2 . The vehicle control apparatus according to claim 1 , further comprising:
a vehicle speed sensor configured to detect a vehicle speed that is a speed of said host vehicle;
an acceleration pedal operation amount sensor configured to detect an acceleration pedal operation amount of said host vehicle; and
a power train actuator configured to change said driving force of said host vehicle,
wherein, said controller is further configured to:
in a case where said target object condition is satisfied, determine that said start moving suppression condition is satisfied when it is determined that said detected vehicle speed is equal to or lower than a specific vehicle speed threshold and said detected acceleration pedal operation amount is equal to or greater than a specific operation threshold;
when it is determined that said start moving suppression condition is not satisfied, control said power train actuator in such a manner that said host vehicle driving force coincides with a normal driving force that is greater as said detected acceleration pedal operation amount is greater; and
when it is determined that said start moving suppression condition is satisfied, control said power train actuator in such a manner that said host vehicle driving force coincides with a driving force that is smaller than said normal driving force.
3 . The vehicle control apparatus according to claim 2 , wherein,
said controller is further configured to:
determine, using image data of said picture taken by said frontward camera, whether or not a target object is located in a frontward obstacle area that is a rectangular area having a longitudinal direction that is frontward in a front rear axis direction of said host vehicle, wherein a width of said rectangular area is a value in accordance with a width of the host vehicle;
when it is determined that said target object is located in said frontward obstacle area, determine that an erroneous start moving suppression condition is satisfied when said detected vehicle speed is equal to or lower than said specific vehicle speed threshold, and said detected acceleration pedal operation amount is equal to or greater than an erroneous start moving operation amount threshold that is greater than said specific operation threshold;
when it is determined that said erroneous start moving suppression condition is satisfied, control said power train actuator in such a manner that said host vehicle driving force coincides with a driving force that is smaller than said normal driving force; and
when said front side target object information includes information on an intermediate target object that is a target object located between said frontward obstacle area and said blind angle detection area, handle said intermediate target object as said blind angle target object in order to determine whether or not said target object condition is satisfied.
