A database unit (154) stores the driving condition data in a driving condition database (160). The driving situation data is obtained by associating a feature amount indicating a feature of a driving operation, driving environment information including a driving location and a road shape, driver information including an attribute of a driver and vehicle type information of the vehicle, and the presence or absence of a driving experience of the driver with respect to the vehicle with a driver identifier. A driving characteristic estimation unit (155) estimates driving characteristics of a driver who currently drives a vehicle on the basis of a driving situation database (160). The database unit (154) determines the presence or absence of the driving experience of the target driver with respect to the target vehicle on the basis of the driving situation database (160), determines whether or not the driving experience of the target driver with respect to the target vehicle has been changed, and updates the driving experience of the target driver with respect to the target vehicle in the driving situation database (160) when it is determined that the driving experience has been changed.

    数据库化部(154)将驾驶状况数据蓄积于驾驶状况数据库(160),驾驶状况数据是将表示驾驶操作的特征的特征量、包含行驶地点和道路形状的行驶环境信息、包含驾驶员的属性和车辆的车型信息的驾驶员信息及驾驶员对车辆的驾驶经验的有无与驾驶员识别符对应起来而得的。驾驶特性估计部(155)基于驾驶状况数据库(160)估计当前驾驶车辆的驾驶员的驾驶特性。数据库化部(154)基于驾驶状况数据库(160)判定对象驾驶员对对象车辆的驾驶经验的有无,判定是否变更了对象驾驶员对对象车辆的驾驶经验,在判定为变更了时更新驾驶状况数据库(160)中的对象驾驶员对对象车辆的驾驶经验。
