Vehicle energy consumption analysis method and system based on kinematics sequences

Abstract

The invention discloses a vehicle energy consumption analysis method based on kinematics sequences, and the method comprises the following steps of obtaining fuel consumption of a vehicle; obtaining power consumption of the vehicle; obtaining accessories energy consumption of the vehicle; obtaining running resistance energy consumption of the vehicle; and calculating energy consumption evaluationindicators including but not limited to the following parts: energy loss rate, carbon dioxide emission, energy consumption equivalent amount, total lifetime energy consumption accumulated value and unit energy consumption. The analysis method comprehensively considers energy consumption of the vehicle from two levels of fuel consumption that takes fuel consumption rate as the direct indicator andpower consumption that takes SOE (energy state) of a battery as the direct indicator, takes the energy consumption and accessories energy consumption corresponding to the driving resistance at the vehicle level as indicators, and finally calculates indicators such as the energy loss rate, carbon emission, energy consumption equivalent amount, total lifetime energy consumption accumulated value, which can provide guidance for the vehicle control strategy optimization.

Description

technical field [0001] The invention relates to the technical field of vehicle energy consumption analysis, in particular to a vehicle energy consumption analysis method and analysis system based on kinematics segments. Background technique [0002] With the shortage of energy worldwide, the problem of energy consumption of vehicles has become increasingly prominent, and the future trend of vehicle types also shows a general trend of electrification. However, for a considerable period of time, the market will still be fuel vehicles, pure electric vehicles, hybrid vehicles Power vehicles "third world" situation. When analyzing the energy consumption of different types of vehicles, a set of analysis methods for this type of vehicles is often adopted. For example, the energy consumption analysis method of traditional fuel vehicles is only based on the relevant conversion method of fuel consumption rate, or is "Well to Wheel" (oil well to wheel) energy consumption calculation m...

Problems solved by technology

When analyzing the energy consumption of different types of vehicles, a set of analysis methods for this type of vehicles is often adopted. For example, the energy consumption analysis method of traditional fuel vehicles is only based on the relevant conversion method of fuel consumption rate, or is "Well to Wheel" (oil well to wheel) energy consumption calculation method based on fuel life cycle, obviously, neither of these two calculation methods can be applied to pure electric vehicles or hybrid vehicles; similarly, for pure electric vehicles The energy consumption analysis method cannot be applied to fuel vehicles or hybrid vehicles

[0003] In addition, at present, in the analysis method of power consumption involving electric vehicles or hybrid vehicles, the capacity state SOC of the battery is often used for related calculations, and this value often leads to large errors in the calculation results.
