Vehicle controller, method and device for calculating vehicle and range thereof

Abstract

The invention discloses a vehicle controller, a vehicle and a method and a device for calculating the range of the vehicle and the range of the vehicle. The method comprises the following steps: periodically collecting vehicle running parameters, ambient temperature and the range of the vehicle in the driving process; Establish the corresponding relationship among the collecting time, vehicle driving parameters, ambient temperature and mileage, and get the two-dimensional decision table; The vehicle driving parameters, ambient temperature and mileage in the two-dimensional decision table are discretized to obtain the two-dimensional decision table after discretization. The data values of vehicle driving parameters, ambient temperature and endurance mileage in the discrete two-dimensional decision table are reduced respectively, and the reduced two-dimensional decision table is obtained. The data values of the factors related to the mileage strength and the mileage data in the reduced two-dimensional decision table are respectively extracted by rules, and the corresponding relationship between the factors related to the mileage strength and the mileage is obtained, so that the calculated mileage is more in line with the actual situation.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a method for calculating the cruising range of a vehicle, a device for calculating the cruising range of a vehicle, a vehicle controller with the computing device, and a vehicle with the computing device. Background technique [0002] At present, the instruments of new energy vehicles are basically equipped with cruising range parameter values. Among them, the cruising range is the cruising ability index of new energy vehicles, which is the total mileage that new energy vehicles can continuously drive under the largest energy reserve. During the use of this function, there are often a series of problems such as the inconsistency between the cruising range and the actual cruising range, such as the obviously inflated cruising range in winter. This is because there is following shortcoming in the technical scheme of existing calculation driving range: [0003] (1) Existing techni...

AI Technical Summary

Problems solved by technology

[0003] (1) Existing technical solutions for calculating driving mileage are often limited by influencing factors

For example, the engineer chooses the vehicle parameters as the influencing factors to model. Due to the limitations of his own experience, the error in the selection of the vehicle parameters will inevitably lead to deviations in the calculation results.

[0004] (2) For the existing calculation model, it is often limited by the accuracy of the model itself

For example, engineers use their own experience to model and build relevant variables, and their understanding of the law of cruising range often deviates from the actual situation.
