20100131139 | Charge planning apparatus - A charge planning apparatus that formulates a control plan for controlling both of a motor and a generator in a hybrid vehicle performs a control plan re-formulation by changing a control index that provides a basis for state of charge (SOC) estimation, when a modification of the control plan based on a current SOC during the travel of the hybrid vehicle results in an excessive charging or discharging portion in a transition of the modified SOC estimation. | 05-27-2010 |
20100152937 | Drive control apparatus for hybrid vehicle - 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. | 06-17-2010 |
20100152939 | Planning apparatus - 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. | 06-17-2010 |
20100161166 | Drive control apparatus for hybrid vehicle, travel schedule making apparatus for hybrid vehicle and travel route prediction apparatus - A drive control apparatus for a hybrid vehicle is disclosed. The apparatus is configured to: record, for every section of a traveled route, a number of times the hybrid vehicle has traveled the section; identify subsequent sections, which the hybrid vehicle is expected to travel after a present position section; calculate, for every subsequent section, a travel probability that the hybrid vehicle travels the subsequent section, based on the number of times; determine a high reliable section based on the travel probability; and perform the drive control of the internal combustion engine and the motor based on the travel schedule when it is determined that the hybrid vehicle has moved into the high reliable section, the travel schedule being made through setting a planned section to the high reliable section. | 06-24-2010 |
20100228459 | Notification apparatus - 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. | 09-09-2010 |
20100292893 | Air-conditioner controlling device - An air-conditioner controlling device includes a first control unit and a second control unit. The first control unit changes an air-conditioner operation from a standard to an energy-saving, when a vehicle is determined to be located in a target area. The target area is defined by a predetermined interval from a target point of the vehicle. The second control unit changes the air-conditioner operation from the energy-saving to the standard, after the first control unit changes the air-conditioner operation from the standard to the energy-saving, in a case that a destination of the vehicle is estimated to be different from the target point. | 11-18-2010 |
20100305799 | Drive control apparatus for hybrid electric vehicle and method for controlling the same - 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. | 12-02-2010 |
20110022255 | Drive control device for hybrid electric vehicle - A drive control device is mounted to a hybrid electric vehicle that has an engine and a motor as a running power source, wherein the hybrid electric vehicle runs under a plurality of running modes that is switched in accordance with accelerator operation. The drive control device specifies a present position of the vehicle. The drive control device defines a schedule of the accelerator operation for each of a plurality of sections in a route from an origin to a destination in order to achieve an enhanced fuel efficient running of the vehicle. The drive control device displays a recommended accelerator operation for a present section of the plurality of sections, in which section the vehicle is presently located, in accordance with the schedule of the accelerator operation and the present position of the vehicle. | 01-27-2011 |
20110066310 | In-vehicle charge and discharge control apparatus and partial control apparatus - 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. | 03-17-2011 |
20110071712 | Driving power control apparatus for vehicle and method for controlling vehicle - A driving power control apparatus for a vehicle having an internal combustion engine and an electric motor includes a charge specifying unit and a schedule specifying unit. When determining that congestion exists ahead based on received wireless information, the charge specifying unit specifies a required charge quantity of a battery, which is needed at a congestion start, such that a charge quantity of the battery remains more than a predetermined quantity at a congestion end after traveling through the congestion using the motor. The schedule specifying unit extracts a partial section in advance of the congestion start. The schedule specifying unit further specifies a schedule of a control index in the partial section, such that the charge quantity of the battery at the congestion start is more than the required charge quantity. | 03-24-2011 |
