Abstract: An eco-drive support device that notifies a driver of the eco-friendliness of a vehicle driving operation being performed by the driver includes: an operating unit that calculates eco-drive support information that indicates the eco-friendliness of the vehicle driving operation being performed by the driver; and a notification control unit that controls a notifying unit to notify the driver of the eco-drive support information, if there is a request from an input unit for notification of the eco-drive support information. In this device, the notification control unit controls the notifying unit to notify the driver of the eco-drive support information though there is not a request from the input unit for notification of the eco-drive support information, if a predetermined condition for providing the eco-drive support information is satisfied.

Abstract: A EFI-ECU 300 that stops an engine when a vehicle has stopped and that starts the engine when an accelerator has been stepped, includes a RAM 304 that stores information from a communication device 301 that acquires information of the outside of the vehicle, and a CPU 302 that determines whether there is need to activate a security device of the vehicle based on information stored in the RAM 304 and that keeps ready condition of the security device if it determines that there is need to activate the security device. Therefore the EFI-ECU 300 enhances the security while the vehicle is stopping.
