摘要:
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.
摘要:
In a drive control apparatus, an information storing unit collects first and second information at predetermined intervals while the vehicle runs and the information storing unit stores the first and second information in a storage device. A schedule effective section extracting unit extracts a schedule effective section from a route from an origin to a destination based on the second information. A control index storage controlling unit defines the schedule of the control index of each of multiple predetermined sections within the schedule effective section based on the first information such that fuel consumption of the engine is reduced in the schedule effective section, wherein the defined schedule of the control index is stored in the storage device. An assist control process unit performs drive control of a motor and an engine based on the schedule of the control index.
摘要:
A temperature increase of a battery of a vehicle in a schedule effect road range is estimated based on an estimate of energy acquirable by regeneration in the schedule effect road range of the vehicle. A special value of the battery upper limit temperature is designated which is obtained by subtracting the temperature increase from a default value of the battery upper limit temperature. A battery upper limit temperature reduction road range is designated which is located just prior to the schedule effect road range. While the vehicle runs the battery upper limit temperature reduction road range, the battery upper limit temperature is set at the special value by being switched from the default value. When the vehicle completes running the battery upper limit temperature reduction road range and starts running the schedule effect road range, the battery upper limit temperature is returned to the default value from the special value.

A planning apparatus for use in a hybrid vehicle specifies a plan section for the purpose of creating a travel plan, and stores the plan section in a durable storage medium. The medium-stored plan section is then presented for an occupant of the vehicle, for the purpose of confirmation. The stored plan section may be modified according to an intention of the occupant, thereby enabling the occupant's intention to be reflected to the plan section. Then, the plan section reflecting the occupant's intention is used to create a travel plan of the hybrid vehicle.
摘要:
In a hybrid vehicle, an ECU collects data of (i) an amount of acquisition electrical power acquired when regeneratively charging a battery and (ii) an amount of requirement electrical power required for operating a motor, for every road section in association with a travel of the vehicle, and records the collected data in a storage device. Thereafter, when a travel course the vehicle is going to travel includes a road section where the amount of acquisition electrical power is greater than an acquisition-related threshold value or a road section where the amount of requirement electrical power is greater than a requirement-related threshold value, a re-plan of a control schedule for the engine and the motor is executed. In contrast, when the travel course does not include such a road section, a re-plan of the control schedule is prohibited.

A semiconductor light-emitting device includes: a first semiconductor layer; a light-emitting layer being disposed on the first semiconductor layer; a second semiconductor layer being disposed on the light-emitting layer, and metal electrodes connected to the first semiconductor layer and the second semiconductor layer. The light-emitting layer is lower in refractive index than the first semiconductor layer. The second semiconductor layer is lower in refractive index than the light-emitting layer. The metal electrodes supply a current to the light-emitting layer.
