CONTROL METHOD FOR ELECTRIC VEHICLE AND CONTROL DEVICE FOR ELECTRIC VEHICLE Russian patent published in 2019 - IPC B60L15/20 H02P23/18 B60W30/20 B60L3/00 B60L50/51 

FIELD: transportation.

SUBSTANCE: group of inventions traction control system of vehicles with electric traction. Control method for electric vehicle, which is made with possibility to control engine torque consists in the following. Value of end torque control command is calculated based on value of target torque and value obtained by multiplying angular speed of drive shaft torsion by feedback gain. Vehicle model is used to estimate period of dead zone during which torque of motor is not transmitted to vehicle drive shaft. Various values are set as feedback amplification separately for period of dead zone and for second period, during which torque of motor is transmitted to drive shaft of vehicle. At that, when the vehicle is in a state immediately before stopping, identical values of feedback gain for the period of the dead zone and for the second period are set. Also disclosed is a device for controlling torque of motor for electric vehicle.

EFFECT: technical result consists in reduction of transmission system vibrations.
