To appropriately control an inter-vehicular distance in consideration of a balance between calorific power of a power source and a radiation amount of a heat sink.SOLUTION: A vehicular speed control apparatus includes: a detection part for detecting an inter-vehicular distance L between a vehicle itself VC2 and a preceding vehicle VC1 traveling ahead thereof; and a control part for controlling a vehicular speed of the vehicle itself so that the inter-vehicular distance detected by the detection part approaches a predetermined target inter-vehicular distance. The control part performs: calculating calorific power of a power source 1 and a radiation amount of a heat sink in the vehicle itself; and changing the target inter-vehicular distance on the basis of a difference between the calculated calorific power and radiation amount.SELECTED DRAWING: Figure 1
【課題】動力源の発熱量と放熱器の放熱量とのバランスを考慮して車間距離を適切に制御する。【解決手段】車速制御装置は、自車VC2とその前方を走行する前車VC1との間の車間距離Lを検出する検出部と、検出部により検出された車間距離が、予め設定された目標車間距離に近づくよう、自車の車速を制御する制御部とを備える。制御部は、自車における動力源1の発熱量と放熱器の放熱量とを計算すると共に、計算された発熱量と放熱量の差に基づいて、目標車間距離を変更する。【選択図】図1
