Problems solved by technology

[0005] However, if a traffic jam starts after the vehicle travels 100 kilometers, and the power consumption during the traffic jam is 10 degrees, then the remaining power of the vehicle can actually travel another 90 kilometers, not the 100 kilometers displayed on the dashboard , at this time, if the user arranges travel according to the mileage of 100 kilometers displayed on the dashboard, the vehicle will not be able to reach the destination, which will bring trouble to the user's travel and easily cause the user to have mileage anxiety
[0006] According to the above analysis, since the existing fuel consumption (power consumption) per unit mileage is only determined according to the proportional relationship between the fuel consumption (power consumption) within the preset mileage and the preset mileage, other factors are not considered. As a result, the estimation of vehicle energy consumption in different driving environments is inaccurate, which further leads to a large difference between the mileage displayed on the instrument panel and the actual mileage, which in turn causes the user to be unable to determine the actual mileage of the vehicle based on the mileage displayed on the instrument panel. range anxiety

Abstract

The invention discloses a method and device for determining energy consumption and a method and device for determining a driving strategy. Influence of multiple factors such as weather parameters, traffic route parameters, driving behavior parameters, vehicle working condition parameters and power source parameters on the vehicle energy consumption is considered; moreover, a weather factor chart,a whole vehicle energy consumption factor chart and a power source factor chart are inquired according to the different energy consumption influence parameters, and the energy consumption influence factors corresponding to the different energy consumption influence parameters are obtained, so that the different energy consumption influence factors are integrated, and the vehicle energy consumptionin the current driving environment is obtained. At the moment, chart query operation according to the parameters is simple, and the consumed time is short; therefore, the vehicle energy consumption in the current driving environment can be quickly obtained, so that the driving range is accurately determined according to the vehicle energy consumption in the current driving environment and the residual oil quantity (electric quantity) of the current vehicle, the driving range displayed by the instrument panel is the same as the actual range, and a user is prevented from generating range anxiety.

Description

technical field [0001] The present application relates to the technical field of vehicles, in particular to a method and device for determining energy consumption and a method and device for determining driving strategies. Background technique [0002] When driving a vehicle for travel, the user needs to pay attention to the parameters displayed on the dashboard in the car, especially the mileage displayed on the dashboard. When the vehicle is a fuel vehicle, the mileage refers to the total mileage that the vehicle can travel continuously under the condition of the largest fuel reserve; Total miles traveled. [0003] In the prior art, the method for determining the driving mileage is: first determine the fuel consumption (power consumption) per unit mileage according to the fuel consumption (power consumption) of the vehicle within the preset mileage, and then determine the fuel consumption (power consumption) according to the remaining fuel quantity ( Remaining power) and...
