Abstract

The invention discloses a driving control method and device of a distributed driving system, and an electric vehicle, the method is applied to a controller, and the method comprises the steps of obtaining a first driving torque required by the current working condition of the automobile; determining a second driving torque of the driving system, wherein the second driving torque is the sum of the maximum driving torque of the first energy storage component and the maximum driving torque of the second energy storage component; when the first driving torque is smaller than or equal to the second driving torque, controlling the first energy storage component and the second energy storage component to provide the required first driving torque; when the first driving torque is larger than the second driving torque, determining a third driving torque of the driving system, and the third driving torque is the sum of the maximum driving torque of a third hub motor belt brake assembly and the maximum driving torque of a fourth hub motor belt brake assembly; and according to the second driving torque and the third driving torque, controlling the driving system to generate the required first driving torque. According to the method, energy consumption can be effectively reduced, and the driving distance of the whole vehicle is increased.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a drive control method and device for a distributed drive system and an electric vehicle. Background technique [0002] Automobile is an important means of transportation in modern society, and it provides people with convenient and comfortable travel services. However, the use of traditional fuel vehicles produces a large amount of harmful exhaust gas and intensifies the dependence on non-renewable petroleum resources. In today's increasingly severe energy and environmental situation, electric vehicles have become an emerging industry that all countries and regions in the world pay more attention to because of their significant advantages in cleanliness and energy saving. [0003] However, electric vehicles use power batteries as the on-board energy source. Due to the limited energy of the power battery pack, the driving range of electric vehicles is short, which affects th...
