摘要:
A fuel-saving driving diagnostic apparatus detects that the vehicle stops based on a vehicle speed indicating a speed of a vehicle, and detects that the vehicle is in an idling state indicating a state in which the vehicle is idled when a number of engine revolutions of the vehicle whose stop is detected is a predetermined threshold or more. The fuel-saving driving diagnostic apparatus determines whether the vehicle in the idling state is in a parking state based on a selection lever and/or a parking brake of the vehicle in the detected idling state. Then the fuel-saving driving diagnostic apparatus diagnoses fuel-saving driving based on an idling parking time for which the parking state of the vehicle is maintained.

An accelerator-off, fuel-cut traveling determining unit (11c) determines whether the number of engine revolutions of a vehicle (1a) 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 (11d) adds up accelerator-off, fuel-cut traveling distances. A fuel-saving driving rating unit (12) rates driving by a driver based on each of the added-up values which were added up by the traveling distance adding-up unit (11d). A fuel-saving driving advice generating unit (13) 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.

A shift lever position determining unit (11b1) determines whether a shift lever position of a vehicle (1a) satisfies predetermined conditions. If the shift lever position is determined to satisfy the predetermined conditions, a travel distance adding-up unit (11c) adds up an optimum shift lever position travel distance. If the shift lever position is determined not to satisfy the predetermined conditions, the travel distance adding-up unit (11c) adds up an inappropriate shift lever position travel distance. A fuel-saving driving rating unit (12) rates driving by a driver based on each added-up value added up by the travel distance adding-up unit (11c). A fuel-saving driving advice generating unit (13) notifies the driver of fuel-saving driving advice together with a rating result in accordance with the rating result. Therefore, it is possible to encourage the driver to select an optimum shift lever position with high fuel efficiency and thereby to improve the driver's knowledge and awareness of the fuel-saving driving.

A vehicle power indication status quantity display unit 16a 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 502 of the vehicle power indication status quantity display unit 16a 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 505 is within the HV eco zone 502, and, if it is determined to be within the HV eco zone 502, the driving being performed is diagnosed as fuel-saving driving. For example, the ratio of the travel distance with the vehicle power indication status quantity 505 staying within the HV eco zone 502 to the one-trip travel distance is turned into a score, and an advice suitable for the score is presented to the driver. In this manner, the driver's awareness about fuel-saving driving at the time of acceleration and deceleration can be increased.
摘要:
A section setting method calculates information relating to an attainable actual fuel efficiency under a vehicle operation performed in consideration of fuel efficiency. To that end, the section setting method collects fuel-efficiency information that is information relating to the fuel efficiency required for a movement from a start point to a destination point of the vehicle, which is obtained under a plurality of kinds of vehicle operations, along with positional information of the vehicle at each time. The section setting method compares change pattern parts of the collected fuel-efficiency information with each other, thereby sequentially connecting the change pattern parts of the fuel-efficiency information from the start point to the destination point. The section setting method sets, as a section used to calculate the actual fuel efficiency, a section obtained by sectioning at points corresponding to the connection points of the change pattern parts connected.
摘要:
A driving support system for giving a support to a driving operation of a vehicle includes a drive history database and a drive teaching unit for specifying a travel route of a vehicle subjected to a driving support. Vehicle information including information about vehicle operation is associated with pertinent route information and is registered as a drive history in the drive history database. The drive teaching unit is configured to extract a drive history corresponding to the specified travel route from the drive history database. The drive teaching unit is further configured as a guide for the driving support to teach information about the extracted drive history to a driver of the vehicle subjected to the driving support.
摘要:
The invention provides a vehicle data analysis method that enables quantitative analysis of characteristics of vehicle data indicating transition in a driver's driving operation, and a vehicle data analysis system using this analysis method. A plurality of vehicle data are collected based a plurality of types of driving operations. Based on an evaluation criterion as an index for evaluating levels of the driving operations, the collected vehicle data are grouped into at least two groups. Characteristic values of the vehicle data differing between these groups are extracted.
