BRAKING CONTROL METHOD AND DEVICE FOR ELECTRIC VEHICLE Russian patent published in 2020 - IPC B60L7/18 B60L7/26 B60L15/20 B60T8/17 

FIELD: transport machine building.

SUBSTANCE: group of inventions relates to a method and a device for braking control for an electric vehicle. Electric vehicle includes the following: electric motor and friction braking assembly. Electric motor functions as a source of actuation and provides recuperative braking force to the vehicle. Friction braking assembly provides friction braking force to vehicle. At that, the control method comprises the following stages: determining the speed / rotation speed parameter proportional to the vehicle speed; perturbing torque is evaluated, which acts on electric motor; control is performed so that electric motor torque is convergent to estimated value of disturbing torque as speed / rotation speed parameter decreases; control is performed so that friction braking friction braking unit converges to value, determined based on the estimated value of the disturbing torque and instructing the torque of the electric motor to converge to almost 0 when the speed / rotation speed parameter becomes almost equal to 0, and determining that the vehicle is in a stop state.

EFFECT: creation of a system aimed at increasing energy efficiency of electric transport by controlling acceleration/deceleration and stoppage of a vehicle.
