Document Type and Number:
Japanese Patent JP6500566
Kind Code:
B2
Abstract:
A control system for a vehicle drive motor includes a motor torque obtaining portion, a current distributing state obtaining portion obtaining a state of current distribution to coils of respective phases of a stator of the motor, a temperature sensor detecting temperature of a specific phase coil, a motor torque control portion updating other phase estimated temperatures by using the coil sensor temperature and an added-up value of a temperature rise per unit time of each of other phase coils at each time point, the motor torque control portion controlling the motor torque by using the other phase estimated temperatures, wherein the temperature rise per unit time of each of the other phase coils at each time point is determined by the motor torque control portion in accordance with a combination of the motor torque and the state of current distribution at each time point.
