Abstract

The invention discloses a torque output method and device for an electric automobile and the electric automobile. The torque output method of the electric automobile comprises the steps that when an electric automobile powering-on signal is detected and the electric automobile is in a stop state, the gear state, the state of a parking brake, the state of a brake pedal and the state of an accelerator pedal are detected; when the gear state is a forward gear state, the parking brake is in a released state, the brake pedal is in a trod state and an accelerator pedal signal is a released signal, a constant-value torque output command is generated; and the constant-value torque output command is sent to a driving motor, and the driving motor outputs the constant-value torque based on the constant-value torque output command. By the adoption of the torque output method and device for the electric automobile and the electric automobile, the response time of the driving motor can be shortened, the acceleration time is shortened, and the acceleration performance of the whole automobile is improved.

Description

technical field [0001] The invention relates to the technical field of automobile design, in particular to a torque output method and device for an electric automobile and the electric automobile. Background technique [0002] The latest national standard "Terms and Definitions of Vehicle and Trailer Types" (GB / T 3730.1-2001) has the following definition for a vehicle: a non-rail-mounted vehicle driven by power with 4 or more wheels, mainly used for : Carrying people and (or) goods; towing vehicles carrying people and (or) goods; special purpose. Energy shortages, oil crises and environmental pollution are intensifying, which have a huge impact on people's lives and are directly related to the sustainable development of the country's economy and society. All countries in the world are actively developing new energy technologies. [0003] As a new energy vehicle with reduced oil consumption, low pollution, and low noise, electric vehicles are considered to be an important w...
