  • Patent number: 11472384
    Abstract: A drive control apparatus is applied to a drive system that is mounted to a vehicle, drives wheels of the vehicle by a motor, and brakes the wheels by a brake apparatus. The drive control apparatus determines a road-surface state of a travel road of the vehicle. The drive control apparatus suppresses slipping of the vehicle by correcting a drive torque by correcting at least either of a motor torque and a brake torque. When determined that the drive torque is to be corrected, the drive control apparatus adjusts a correction amount of the drive torque by adjusting the motor torque with higher priority than the brake torque in response to be determined that the road-surface state is rough.

  • Publication number: 20220250479
    Abstract: A control device includes a limit value calculation unit that, when a rotary electric machine is driven as an electric motor, subtracts a power consumption value from a discharge power limit value of a power storage device to calculate an input limit value, and a control unit that, when the rotary electric machine is driven as an electric motor, controls the inverter so that a power consumption value of the rotary electric machine is equal to or less than the input limit value. In response to an abnormality occurring wherein a normal power consumption value cannot be achieved when the rotary electric machine is driven as an electric motor, the limit value calculation unit sets the power consumption value of the electrical device for calculating the input limit value on an upper limit side of a range in which the power consumption value takes when the electrical device is driven.
