モータ制御装置
Document Type and Number:
Japanese Patent JP7200473
Kind Code:
B2
Abstract:
To reduce a calculation load of a travel control device, and obtain a propulsive force of front and rear wheels without needing high speed communication.SOLUTION: A motor control device 4 acquires a vehicle speed detection signal from a vehicle speed sensor 9, and acquires rotation detection signals Sa and Sb from a resolver 6. The motor control device 4 determines whether or not front wheels WH1 and WH2 slip based on a travel speed and the number of motor revolutions. The motor control device 4 acquires a torque command value from an ECU 11 for controlling travel of the vehicle when having determined that the front wheels do not slip, and controls the motor 2 so that a torque indicating the torque command value is output from the motor 2. The motor control device 4 acquires a vehicle speed detection signal from the vehicle speed sensor 9, acquires rotation detection signals Sa and Sb from the resolver 6, and executes control of the number of revolutions for controlling the motor 2 so that a deviation between the target number of revolutions and the number of motor actual revolutions becomes 0 when having determined that the front wheels WH1 and WH2 slip.SELECTED DRAWING: Figure 1
