1. An energy estimation apparatus comprising:
a probability setting unit that sets a vehicle speed probability that is a probability of a vehicle reaching a certain vehicle speed on a traveling route that is specified by traveling route information;
a vehicle speed pattern estimation unit that estimates a vehicle speed variation pattern of the vehicle on the traveling route based on the traveling route information and the vehicle speed probability;
a traveling load estimation unit that estimates traveling load characteristics of the vehicle on the traveling route; and
an energy estimation unit that estimates energy required for traveling of the vehicle using the traveling load characteristics and the vehicle speed variation pattern.
