DRIVE SUPPORT APPARATUS

To reduce travel energy and secure a high drivability in balance.SOLUTION: A drive support apparatus includes: a vehicle-itself speed obtainment part 11 for obtaining a vehicular speed Vof a vehicle itself 50; a preceding-vehicle information obtainment part 12 for obtaining an inter-vehicle distance Xand a relative speed (V-V) between the vehicle itself 50 and a preceding vehicle 60; a target inter-vehicle time setup part 13 for setting target inter-vehicle time T; a target brake-drive force computation part 14 for computing target brake-drive force Tfor causing the vehicle itself 50 to track the preceding vehicle 60; and a brake-drive control part 15 for controlling brake-drive force to be generated by the vehicle itself 50 so as to generate target brake-drive force Tin the vehicle itself 50. Further, the target brake-drive force computation part 14 computes target brake-drive force Ton the basis of the inter-vehicle distance X, relative speed (V-V), and travel resistance of the vehicle itself 50.SELECTED DRAWING: Figure 1 【課題】走行エネルギの低減と高いドライバビリティの確保とを両立させる。【解決手段】自車両５０の車速Ｖｆを取得する自車速取得部１１と、自車両５０と先行車両６０との間の車間距離Ｘｄｉｓｔ及び相対速度（Ｖｆ−Ｖｐ）を取得する先行車両情報取得部１２と、目標車間時間Ｔｈｗを設定する目標車間時間設定部１３と、先行車両６０に自車両５０を追従させる目標制駆動力Ｔｏｐｔ＿ｒｅｆを演算する目標制駆動力演算部１４と、自車両５０に目標制駆動力Ｔｏｐｔ＿ｒｅｆが発生するように自車両５０に発生させる制駆動力を制御する制駆動制御部１５と、を備え、目標制駆動力演算部１４は、車間距離Ｘｄｉｓｔ、相対速度（Ｖｆ−Ｖｐ）、及び自車両５０の走行抵抗に基づいて目標制駆動力Ｔｏｐｔ＿ｒｅｆを演算する。【選択図】図１
