20090299595 | Driving evaluating apparatus, driving evaluating method, and computer program for driving evaluation - In a driving evaluating apparatus, a first unit detects a stable acceleration area that is an area in which an accelerator opening rate fluctuates within a predetermined range, a second unit detects a vehicle speed slowdown area that is an area in which a vehicle speed is decreased according to a reference speed obtained from the vehicle speed in the stable acceleration area and to an actual vehicle speed representing an actual speed of a vehicle, a third unit detects a recovering acceleration area that is an area in which an excessive recovering acceleration is performed according to a reference accelerator opening rate corresponding to a start point of the vehicle speed slowdown area and to an actual accelerator opening rate representing an actual value of the accelerator opening rate, and a judging unit judges whether the accelerator operation is appropriate according to the recovering acceleration area. | 12-03-2009 |
20110093152 | FUEL-SAVING DRIVING DIAGNOSTIC DEVICE, IN-VEHICLE SYSTEM, DRIVE CONTROL DEVICE, AND FUEL-SAVING DRIVING DIAGNOSTIC PROGRAM - A fuel-saving driving diagnostic device stores an external power amount which indicates an amount of power charged by an external device and an internal power amount which indicates an amount of power charged by vehicle driving. The fuel-saving driving diagnostic device calculates a driving power amount which indicates an amount of power required for vehicle driving based on the stored external power amount, stored internal power amount, and an amount of power a vehicle currently has, and makes a diagnosis of fuel-saving driving based on the calculated driving power amount and the stored external power amount. As a result, sufficient information is calculated for prompting the driver of a plug-in hybrid car to do the fuel-saving driving. | 04-21-2011 |
20110125357 | FUEL-SAVING DRIVING DIAGNOSTIC DEVICE, FUEL-SAVING DRIVING DIAGNOSTIC SYSTEM, CONTROL DEVICE OF ELECTRIC DRIVE DEVICE, FUEL-SAVING DRIVING RATING DEVICE, AND FUEL-SAVING DRIVING DIAGNOSTIC METHOD - A vehicle power indication status quantity display unit displays on an indicator a vehicle power indication status quantity obtained by dividing the torque required for driving a hybrid vehicle by the upper limit value of the torque that does not excessively increase the fuel consumption. A HV eco zone of the vehicle power indication status quantity display unit is the zone that is determined by the upper limit value and the lower limit value of the HV eco zone that indicates the motor is being effectively used to drive the vehicle. A check is made to determine whether the vehicle power indication status quantity is within the HV eco zone, and, if it is determined to be within the HV eco zone, the driving being performed is diagnosed as fuel-saving driving. | 05-26-2011 |
20110133921 | FUEL-SAVING DRIVING DIAGNOSTIC DEVICE, FUEL-SAVING DRIVING DIAGNOSTIC SYSTEM, CONTROL DEVICE OF PRIME MOVER, FUEL-SAVING DRIVING RATING DEVICE, AND FUEL-SAVING DRIVING DIAGNOSTIC METHOD - An accelerator-off, fuel-cut traveling determining unit determines whether the number of engine revolutions of a vehicle is equal to or higher than a predetermined value, whether an accelerator opening rate is equal to or lower than a predetermined value, and whether a traveling state is an accelerator-off, fuel-cut traveling state where a quantity of fuel injection to an engine is 0. When it is determined that the traveling state is the accelerator-off, fuel-cut traveling state, the traveling distance adding-up unit adds up accelerator-off, fuel-cut traveling distances. A fuel-saving driving rating unit rates driving by a driver based on each of the added-up values which were added up by the traveling distance adding-up unit. A fuel-saving driving advice generating unit notifies the driver of a fuel-saving driving advice together with a rating result in accordance with the rating result. Therefore, it is possible to encourage the driver to perform early engine operation by an engine braking, and to enhance the driver's awareness of fuel saving driving. | 06-09-2011 |
20110137512 | FUEL-SAVING DRIVING DIAGNOSTIC DEVICE, FUEL-SAVING DRIVING DIAGNOSTIC SYSTEM, TRAVEL CONTROL DEVICE, FUEL-SAVING DRIVING RATING DEVICE, AND FUEL-SAVING DRIVING DIAGNOSTIC METHOD - A shift lever position determining unit ( | 06-09-2011 |
20110148618 | FUEL-SAVING DRIVING DIAGNOSTIC DEVICE, FUEL-SAVING DRIVING DIAGNOSTIC SYSTEM, TRAVEL CONTROL DEVICE, FUEL-SAVING DRIVING RATING DEVICE, AND FUEL-SAVING DRIVING DIAGNOSTIC METHOD - An accelerator opening determining unit determines whether an accelerator opening achieved through an accelerator operation by a driver of a vehicle exceeds an upper limit value thereof. A travel distance adding-up unit adds up a travel distance within accelerator-opening upper limit value when the accelerator opening is not determined to exceed the upper limit value. When the accelerator opening is determined to exceed the upper limit value, the travel distance adding-up unit adds up a travel distance exceeding accelerator-opening upper limit value. A fuel-saving driving rating unit rates the driving of the driver based on each added-up value added up by the travel distance adding-up unit. | 06-23-2011 |
20120249794 | IMAGE DISPLAY SYSTEM - An image display system including a synthesized image generation section that generates a synthesized image representing a vehicle and circumstances around the vehicle viewed from a virtual viewpoint based on captured images obtained by cameras disposed on the vehicle, a navigation device that displays the synthesized image and the captured images on a display screen, an obstacle detection section that detects an obstacle, and an indication addition section that, when the obstacle is detected, adds an alarm indication to call attention to at least one of an area of the display screen except the synthesized image, and a surrounding area of the synthesized image is provided. | 10-04-2012 |
20120314072 | IMAGE GENERATION APPARATUS - A shift determining part of an image display system determines a traveling direction of a vehicle. A composite image generator generates a composite image that shows a periphery of the vehicle and an area that is in a direction opposite to the determined traveling direction of the vehicle in a seamless manner. The periphery is viewed from a virtual viewpoint that is set looking down at the vehicle. A display displays a display image including the composite image. Since the display image includes the composite image that shows the area that is in the direction opposite to the determined traveling direction of the vehicle, a user can notice an object that exists in the direction opposite to the traveling direction of the vehicle by looking at the display image. | 12-13-2012 |
20140055487 | IMAGE GENERATOR - An image acquisition part acquires a plurality of shot images captured by a plurality of cameras disposed on a vehicle, each of the plurality of shot images showing a periphery of the vehicle. An image composer projects data of the plurality of shot images onto a virtual projection surface corresponding to the periphery of the vehicle, and generates a composite image showing the periphery of the vehicle viewed from a virtual viewpoint, using the data projected onto the virtual projection surface. The image composer uses, as the virtual projection surface, a special virtual projection surface that includes a curved area having an upward convex curve. The curved area includes an area where a distance from a location of the vehicle is relatively short and a slope is relatively high, and another area where the distance from the location of the vehicle is relatively long and the slope is relatively low. | 02-27-2014 |
