Vehicle control apparatus and control method thereof

Abstract

Disclosed herein are a vehicle control apparatus and a control method thereof. The vehicle control apparatus includes an input unit configured to receive a current yaw rate value, a current steering angle value, and a current lateral acceleration value detected by a detection device, an estimator configured to obtain an estimated lateral acceleration value of lateral acceleration estimation modelinformation on the basis of the received current yaw rate value and current steering angle value, a determiner configured to determine that the current lateral acceleration value is abnormal when thereceived current lateral acceleration value is not equal to the estimated lateral acceleration value of the lateral acceleration estimation model information, and a controller configured to receive the current yaw rate value, the current steering angle value, and the current lateral acceleration value, deliver an estimation command to the estimator, and deliver a determination command to the determiner.

Description

technical field [0001] The present invention relates to a vehicle control device and a control method thereof. Background technique [0002] Generally, a conventional ESC (Electronic Stability Control: Electronic Stability Control) device controls the posture of the vehicle to prevent the vehicle from running unstable. [0003] At this time, conventional ESC devices use a lateral acceleration sensor, which is a detection device for detecting lateral acceleration values, to judge the movement of the vehicle based on the driver's steering input to determine whether to execute the control. [0004] As an example, as described in Korean Granted Patent Publication 10-1627649 (2016.05.31), it is disclosed that an inertial sensor including a lateral acceleration sensor is used to determine whether the control of the ESC device is executed or not, thereby improving the stability of the ESC device. A vehicle control device and a control method thereof. [0005] However, in the case...

Problems solved by technology

[0005] However, in the case of conventional inertial sensors including lateral acceleration sensors, when an abnormal (abnormal) value is output according to the external environment or internal environment, the control execution state of the ESC device changes, and the vehicle behaves undesirably to the driver. change in direction and move

[0006] As a result, conventional ESC devices using lateral acceleration sensors are limited in preventing misuse before they occur, so there is a limit to improving the stability of the vehicle.
