Title:
FUEL CONSUMPTION SAVING MANAGEMENT SYSTEM
Document Type and Number:
Japanese Patent JP2005337229
Kind Code:
A
Abstract:

To accurately monitor deceleration driving by engine brake in a vehicle provided with an auxiliary brake.

This system is constituted by providing information detection means 13 to 15 for detecting information related to fuel flow rate of the vehicle having the auxiliary brake and/or opening of an accelerator and use of the auxiliary brake in an on-vehicle analysis device 1. An information processing means 3 for calculating cumulative running distance for running in a condition in which opening of the accelerator is zero and in a condition in which the auxiliary brake is not used and an information storage means 4 for storing cumulative running distance calculated by the information processing means are provided in the on-vehicle analysis device and/or an office analysis device 32. Preferably, the condition in which opening of the accelerator is zero is when fuel flow rate is less than a predetermined set value and/or opening of the accelerator is substantially zero. This system is further provided with an information detection means 11 for detecting vehicle speed. Preferably, the information processing means calculates cumulative running distance based on vehicle speed and elapse time for running in the condition in which opening of the accelerator is zero and in the condition in which the auxiliary brake is not operated.
