Abstract

The embodiment of the present invention discloses a method and system for obtaining optimal vehicle efficiency, wherein the method includes: establishing a force model of the vehicle; sampling the speed of the vehicle to obtain feedback data, and obtaining driving resistance according to the force model of the vehicle Equivalent coefficients A, B, C; according to the equivalent coefficients A, B, C of driving resistance and the mass of the vehicle, determine the required torque of the vehicle; set the torque interval to filter the motor high-efficiency point to output the optimal torque to realize the vehicle optimal efficiency. This scheme establishes the mathematical model of the whole vehicle, and uses the equivalent force coefficient of the whole vehicle in the closed-loop adjustment to meet various working conditions in the operation of the whole vehicle. Optimize the calculation method, look up the table, difference, weight, advance calibration and other methods to improve the calculation efficiency.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a method and system for obtaining optimum efficiency for vehicles. Background technique [0002] With the development of new energy technology, the power of new energy car manufacturers has grown stronger, and my country has been the largest country in the production and sales of new energy for three consecutive years. However, due to its new materials, new structure, new power and other characteristics, new energy vehicles will inevitably bring new problems and new challenges. For example, although the electric drive system has higher conversion efficiency than the traditional internal combustion engine, due to the slow development of battery technology at this stage, the phenomenon that the energy density of the battery system is far lower than that of fuel will still exist, and will even exist for a long time. Therefore, the mileage anxiety of electric vehicles is...
