Notification apparatus
First Claim
1. A notification apparatus having a regeneration brake system that uses electricity generation load of a motor as a braking force to a tire of a vehicle, and collects regenerated electric energy to a vehicle battery, the apparatus comprising:
- a notification unit notifying a driver of information;
a loss calculation unit calculating loss information regarding energy loss that is defined as difference between a decrease of kinetic energy due to braking by the driver and regeneration by the regeneration brake in the course of braking;
a control unit generating energy information regarding the energy loss and controlling notification of the energy information for the driver by the notification unit based on the loss information calculated by the loss calculation unit;
a position detector detecting a current position of the vehicle;
an information storage storing the loss information of the energy loss during travel of the vehicle in a plurality of geographical areas in a statistical manner; and
a loss recorder statistically recording, in the information storage, the loss information calculated by the loss calculation unit in association with each of the plurality of geographical areas in which the energy loss is created based on the position of the vehicle detected by the position detector, whereinthe control unit calculates frequency information about a frequency of the energy loss in each of the plurality of geographical areas based on the information recorded in the information storage, andthe control unit notifies the drive of an entrance of the vehicle into an energy loss geographical area that has an above-threshold frequency of the energy loss, at the time of entrance of the vehicle into the energy loss geographical area, based on the information stored in the information storage and the route information acquired by the route acquisition unit.

Abstract
A re-generation instruction apparatus has a re-generation instruction computer that receives brake operation information from a re-generation control computer for calculating an energy loss in a total energy from speed reduction by the brake operation of the driver, which is lost by a re-generation brake system. The calculated energy loss is utilized for preparing notification for the driver in various situations such as a pre-travel notification, a during-travel notification and/or an after-travel notification.
