Title:
VEHICLE MOTOR CONTROL SYSTEM, AND, VEHICLE MOTOR CONTROL METHOD
Document Type and Number:
Japanese Patent JP2022077726
Kind Code:
A
Abstract:
To suppress overshoot of motor output due to communication delay, and furthermore to enable a battery to be protected even when torque limit does not function in a motor control device, in a vehicle motor control system.SOLUTION: In a vehicle control device 10, motor target torque is calculated, and first motor torque limit value is calculated on the basis of power available by a motor. The smaller of the motor target torque and the first motor torque limit value is transmitted as torque requested by the motor to a motor control device 20. In the motor control device 20, second motor torque limit value is calculated on the basis of the power available by the motor or current available by the motor which are received from the vehicle control device 10. The smaller of the motor request torque and the second motor torque limit value received from the vehicle control device 10 is set as final motor torque.SELECTED DRAWING: Figure 1
