These costs are often interrelated, i.e. a heavily used vehicle both consumes more fuel and is subject to greater wear and tear, resulting in increased service costs
Nevertheless, the problem with businesses that use heavy vehicles in their business is that it is difficult to determine how much of the vehicle's fuel consumption and wear is due to, for example, inattentive driving and how much is due to adverse traffic conditions such as extremely bumpy ground and / or or heavy traffic urban environments
Although the disclosed system attempts to disclose to the driver a way in which the vehicle can be driven in an efficient manner, the system includes shortcomings in how this assessment is made and, therefore, an improved process is needed to assess the driver's performance in terms of fuel consumption.

Embodiment Construction
[0025] In this specification, the term vehicle interior sensor means a sensor that acquires data only from the relative motion of the vehicle (i.e. the change in motion from one moment to another), which does not use data from external systems such as positioning systems or maps database information. Such a vehicle interior sensor may consist, for example, of a lateral acceleration sensor, i.e. the signal provided by this sensor makes it possible to determine the rate of change of the vehicle's speed in the lateral direction, e.g. . In addition, the sensors may include wheel speed sensors, which provide signals from which the speed of rotation of the wheels and the distance traveled can be determined; steering angle sensors, which provide signals from which the angle of the steered wheels relative to the longitudinal axis of the vehicle can be determined; and A sensor module that provides a signal that can be used to calculate the steering rate (ie, how fast the vehicle is tu...

The present invention relates to a device for determining a fuel consumption behavior of a driver of a vehicle for at least a first segment of a distance the vehicle is 5 traveling, wherein said first segment is constituted by at least one downhill slope. The device comprises: - means for determining whether the vehicle is in said segment, - means for, when the vehicle is in said segment, 10 continuously, or with certain or predetermined intervals, determine whether the vehicle driver is taking a first measure, wherein said first measure constitutes a measure for take off of a positive motor torque, - means for determining a measurement of said first measure 15 during said segment, and - means for, based on said measurement, determining a parameter value representing a fuel consumption behavior starting from predetermined criteria.
Description
technical field [0001] The invention relates to a system for determining the fuel consumption behavior of a vehicle driver, in particular to a device for evaluating the fuel consumption behavior of a vehicle driver according to the preamble of claim 1 . Background technique [0002] When driving heavy vehicles such as trucks, buses, etc., the economic performance of the vehicle has an increasing effect on the profitability of the business done with the vehicle over time. In addition to vehicle acquisition costs, the largest expense items for vehicles consist of fuel costs and service costs. These costs are often interrelated, ie a heavily used vehicle both consumes more fuel and is subject to greater wear and tear, resulting in increased service costs. Nevertheless, the problem with businesses that use heavy vehicles in their business is that it is difficult to determine how much of the vehicle's fuel consumption and wear is due to, for example, inattentive driving and how ...
