  • Vehicle control apparatus and vehicle control method
    Patent number: 10940735
    Abstract: Provided are a vehicle control apparatus and a vehicle control method, including: a sensor configured to sense a vehicle speed value, operation information of an actuator for generating a torque in a stabilizer bar of an active roller stabilizer (ARS), and operation information of the stabilizer bar; and a controller configured to calculate a target torque value that is to be generated in the stabilizer bar on the basis of the sensed vehicle speed value, the sensed operation information of the actuator, and the sensed operation information of the stabilizer bar, and to determine whether the sensed vehicle speed value is a target vehicle speed value that is set to perform an ARS control mode, and in response to the sensed vehicle speed value determined to be the target vehicle speed value, and determine a deadband period in which a torque of the actuator is not transmitted, using a change value of a torque value and a change state of the torque value while the torque value is tracing the calculated target torq
