  • Publication number: 20230166606
    Abstract: A drive control apparatus to be applied to an electric vehicle includes a controller. The controller is configured to limit a change rate of a torque to be outputted from an electric motor of the electric vehicle on the basis of a first limit mode in a case where the torque is less than a threshold torque, in a period of a first traveling state in which the electric vehicle travels on an uphill road where a level of likelihood of an occurrence of a slip is estimated to be equal to or greater than a threshold, and configured to limit the change rate of the torque on the basis of a second limit mode that is more flexible than the first limit mode in a case where the torque is equal to or greater than the threshold torque in the period of the first traveling state.

  • Patent number: 11613258
    Abstract: A vehicle control device includes a driving force setting unit and a motor controller. The driving force setting unit sets a first requested driving force on the basis of accelerator opening and makes dulling processing on it to set a second requested driving force. The motor controller controls a motor driving force on the basis of the second requested driving force. The motor controller executes a slip control on the condition that the driving wheel slips on accelerated travel. The slip control includes controlling the motor driving force on the basis of a limited driving force smaller than the second requested driving force. In stopping the slip control, the motor controller compares the first requested driving force and the motor driving force. On the condition that the former is smaller than the latter, the motor controller controls the motor driving force on the basis of the first requested driving force.

  • Publication number: 20220242251
    Abstract: A vehicle control apparatus controls a traveling motor coupled to wheels. The vehicle control apparatus includes a torque setting unit and a motor control unit. The torque setting unit sets a first target torque and a second target torque as target torques of the traveling motor. The first target torque changes based on an accelerator operation performed by a vehicle' s driver. The second target torque changes more gradually than the first target torque. The motor control unit controls the traveling motor based on the first target torque or the second target torque. When the vehicle is moved forward without the accelerator operation, the torque setting unit sets the first target torque and the second target torque to a regenerative side. When the vehicle having been stopped is moved forward without the accelerator operation, the motor control unit controls the traveling motor based on the first target torque.
