Abstract

The present invention provides a driving control method and device for a vehicle. The vehicle includes at least two carriages. The driving control method of the vehicle includes the following steps: acquiring power information of power batteries corresponding to each carriage; According to the power information of the power battery corresponding to each carriage, obtain the grade allocated to each carriage and the load distributed to each carriage; according to the grade assigned to each carriage and the load distributed to each carriage, obtain the output torque. This method effectively avoids the problem of unbalanced electric power of the power batteries of each carriage when the vehicle runs for a long time.

Description

technical field [0001] The invention relates to the field of vehicle control, in particular to a vehicle drive control method, device and vehicle. Background technique [0002] At present, some vehicles are driven by electric traction, such as rail vehicles, buses with multiple carriages, etc., and each carriage of these vehicles is equipped with a power battery and a motor controller connected to the power battery, a drive motor, and a power battery. It can supply power to the motor controller and drive motor to meet the needs of the vehicle. However, when the vehicle runs for a long time, there will be a problem that the power batteries of each compartment are unbalanced. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0004] Therefore, the first object of the present invention is to provide a driving control method for a vehicle. This method can reasonably allocate...
