Automobile climbing control method and automobile climbing control device

Abstract

The invention provides an automobile climbing control method, which comprises the following steps: detecting an inclination angle signal when an automobile climbs a slope; calculating a corresponding control current value according to the inclination angle signal; and controlling a motor of the automobile according to the control current value to keep the maximum motor output torque of the motor when the automobile climbs the slope. The invention provides the simple and efficient automobile climbing control method and a corresponding device to solve the problems of an electric automobile and a hybrid power automobile during climbing the slope, so the automobiles can climb the slope steadily, and the technical defect that the motor is burnt down due to overlarge accelerator or the automobiles go backwards and glide down due to insufficient climbing force is avoided, so the safety of vehicles is improved.

Description

technical field

[0001] The invention relates to the technical field of automobile manufacturing, in particular to an automobile climbing control method and a climbing control device. Background technique

[0002] With the shortage of energy and the aggravation of environmental pollution, the development of the traditional automobile industry is facing many difficulties. Therefore, the emergence of electric vehicles and hybrid vehicles is favored by the majority of automobile manufacturers and consumers, and has become a hot spot in the development of automobiles. Electric vehicles and hybrid vehicles refer to vehicles powered by electric energy, and generally use high-efficiency rechargeable batteries or fuel cells as power sources. Since electric energy is a secondary energy source, it can come from various sources such as wind energy, water energy, nuclear energy, thermal energy, and solar energy. Therefore, electric vehicles are zero-emission vehicles, which can effective...
