PROBLEM TO BE SOLVED: To alleviate a driver's sense of incongruity due to meandering of an own vehicle that accompanies control, while achieving suppression of deterioration of follow-up performance due to a phase delay.SOLUTION: A steering assistance control apparatus is provided, comprising: a positional deviation calculator that calculates a lateral positional deviation between an own vehicle and a steering follow-up object, based on a detection signal by a sensor; a target value calculator that calculates a steering-related control target value, based on a dead zone filter provided with a dead zone for a variation amount of input signals and based on the lateral positional deviation filtered by the dead zone filter; and a steering driver that drives a steering mechanism, based on the control target value.SELECTED DRAWING: Figure 4
【課題】制御に伴い自車両がふらつくことによる運転者の違和感の緩和を、位相遅れに起因した追従性能の低下抑制を図りつつ実現する。【解決手段】本発明の操舵支援制御装置は、センサによる検出信号に基づき自車両と操舵追従対象との横方向位置偏差を算出する位置偏差算出部と、入力信号の変化量に対する不感帯をもつ不感帯フィルタと、不感帯フィルタによりフィルタリングされた横方向位置偏差に基づき、操舵についての制御目標値を算出する目標値算出部と、制御目標値に基づき操舵機構を駆動する操舵駆動部とを備えている。【選択図】図4
