Abstract

The invention discloses a motor control method and device for an electric vehicle. The motor control method comprises the steps of obtaining current driving information and current road condition information of the vehicle; and, in response to detection of obstacle information from the current road condition information, calculating energy-saving driving torque information according to the current driving information and the obstacle information, and outputting the energy-saving driving torque information to a motor controller to control the output torque of a motor. Reasonable distribution of torque for motor control can be effectively improved, and meanwhile, a certain active safety function is achieved, so that the motor control efficiency is effectively improved, the safety of the electric automobile is improved, the energy consumption of the electric automobile is effectively reduced, and the endurance mileage of the electric automobile is increased.

Description

technical field [0001] The invention relates to the technical field of vehicle control, in particular to a motor control method and device for an electric vehicle. Background technique [0002] While the number of global car ownership is increasing year by year, environmental problems such as the greenhouse effect are becoming increasingly prominent. Considering the depletion of fossil energy, the development of new energy vehicles represented by pure electric vehicles has become the best choice. Pure electric vehicles have the advantages of no pollution, low noise, and high efficiency, and have a wide range of energy sources that are almost inexhaustible. They are one of the important directions for future automotive development. [0003] Since the birth of the first pure electric car in the 1890s, it reached its production peak for the first time in the early 20th century, occupying about 40% of the car market. Subsequently, due to many elements such as battery technology...
