A vehicle driving assistance apparatus comprising: a sensor adapted to detect an object around an own vehicle; and a processing apparatus adapted to determine whether the object detected by the sensor is a static vehicle or a roadside static object, carries out driving assistance if a first driving assistance carrying-out condition is satisfied when determining the object as a static vehicle, and to carry out the driving assistance if a second driving assistance carrying-out condition is satisfied when determining the object as a roadside static object, wherein a threshold concerning the first driving assistance carrying-out condition is lower than a threshold concerning the second driving assistance carrying-out condition, characterized by when determining the object as a static vehicle, the processing apparatus is adapted to calculate a first index value indicating a probability that the object is a static vehicle, to determine based on a third driving assistance carrying-out condition whether to carry out the driving assistance if the calculated first index value is less than a first predetermined reference value, and to determine based on the first driving assistance carrying-out condition whether to carry out the driving assistance if the calculated first index value is greater than or equal to the first predetermined reference value, and the threshold concerning the first driving assistance carrying-out condition is lower than a threshold concerning the third driving assistance carrying-out condition, and when determining the object as a roadside static object, the processing apparatus is adapted to calculate a second index value indicating a probability that the object is a roadside static object, to determine based on the third driving assistance carrying-out condition whether to carry out the driving assistance if the calculated second index value is less than a second predetermined reference value, and to determine based on the second driving assistance carrying-out condition whether to carry out the driving assistance if the calculated second index value is greater than or equal to the second predetermined reference value, and the threshold concerning the second driving assistance carrying-out condition is higher than a threshold concerning the third driving assistance carrying-out condition. a sensor adapted to detect an object around an own vehicle; and a processing apparatus adapted to determine whether the object detected by the sensor is a static vehicle or a roadside static object, carries out driving assistance if a first driving assistance carrying-out condition is satisfied when determining the object as a static vehicle, and to carry out the driving assistance if a second driving assistance carrying-out condition is satisfied when determining the object as a roadside static object, wherein a threshold concerning the first driving assistance carrying-out condition is lower than a threshold concerning the second driving assistance carrying-out condition, characterized by when determining the object as a static vehicle, the processing apparatus is adapted to calculate a first index value indicating a probability that the object is a static vehicle, to determine based on a third driving assistance carrying-out condition whether to carry out the driving assistance if the calculated first index value is less than a first predetermined reference value, and to determine based on the first driving assistance carrying-out condition whether to carry out the driving assistance if the calculated first index value is greater than or equal to the first predetermined reference value, and the threshold concerning the first driving assistance carrying-out condition is lower than a threshold concerning the third driving assistance carrying-out condition, and when determining the object as a roadside static object, the processing apparatus is adapted to calculate a second index value indicating a probability that the object is a roadside static object, to determine based on the third driving assistance carrying-out condition whether to carry out the driving assistance if the calculated second index value is less than a second predetermined reference value, and to determine based on the second driving assistance carrying-out condition whether to carry out the driving assistance if the calculated second index value is greater than or equal to the second predetermined reference value, and the threshold concerning the second driving assistance carrying-out condition is higher than a threshold concerning the third driving assistance carrying-out condition.
