Driving support control device of vehicle, driving support system of vehicle, and driving support control method of vehicle
A driving support control device of a vehicle is provided including an acquiring unit configured to acquire a traveling state of the vehicle which is detected and a traveling environment of the vehicle, and a control unit, configured to, in a case where zero-point learning of a yaw rate sensor has not been completed, cause a driving support unit to execute collision avoidance support using a reduced operational area reduced from a reference operational area which becomes a reference in view of an error of the yaw rate sensor as an operational area of collision avoidance support, and the traveling state of the vehicle and the traveling environment of the vehicle.
1. A driving support control device of a vehicle comprising:
an acquiring unit configured to acquire a traveling state of the vehicle which is detected and a traveling environment of the vehicle; and
a control unit configured to, for a state in which a zero-point learning of a yaw rate sensor has not been completed, cause a driving support unit to execute collision avoidance support using the traveling state of the vehicle, the traveling environment of the vehicle, and a reduced operational area,
wherein
the zero-point learning comprises a calibration process performed by the yaw rate sensor in which the zero point of the yaw rate sensor is determined, and
the reduced operational area comprises an area that is reduced relative to a reference operational area, which becomes a reference in view of an error of the yaw rate sensor as an operational area of collision avoidance support.
2. The driving support control device of the vehicle according to claim 1 ,
wherein the control unit reduces the reference operational area in view of a maximum error of the yaw rate sensor.
3. The driving support control device of the vehicle according to claim 1 ,
wherein the control unit uses the reference operational area in a case where zero-point learning of the yaw rate sensor has been completed.
