To efficiently control driving force when a wheel passes a difference in level during vehicle travel control.SOLUTION: A vehicle travel support apparatus includes: a vehicle travel control device for controlling the travel of a vehicle; and a travel state acquisition device for acquiring travel state information indicating the travel state of the vehicle. On the basis of the travel state information, the vehicle travel control device detects that a first wheel of the vehicle has got over a difference in level. On the basis of the travel state information, the vehicle travel control device acquires first driving force required for the first wheel to get over the difference in level or a change in the travel state when the first wheel passes the difference in level, as reference information. On the basis of the reference information, the vehicle travel control device estimates second driving force to be required for a second wheel of the vehicle to get over the difference in level. When the second wheel passes the difference in level after the first wheel, the vehicle travel control device allows the estimated second driving force to be generated.SELECTED DRAWING: Figure 13
【課題】車両走行制御の最中に車輪が段差を通過する際に駆動力を効率的に制御すること。【解決手段】車両走行支援装置は、車両の走行を制御する車両走行制御装置と、車両の走行状態を示す走行状態情報を取得する走行状態取得装置と、を備える。車両走行制御装置は、走行状態情報に基づいて、車両の第1車輪が段差を乗り越えたことを検出する。車両走行制御装置は、走行状態情報に基づいて、第1車輪が段差を乗り越えるために要した第1駆動力、あるいは、第1車輪が段差を通過する際の走行状態の変化を、基準情報として取得する。車両走行制御装置は、基準情報に基づいて、車両の第2車輪が段差を乗り越えるために必要な第2駆動力を推定する。第1車輪の後に第2車輪が段差を通過する際、車両走行制御装置は、推定された第2駆動力を発生させる。【選択図】図13
