Patent number: 11377149Abstract: A vehicle control system includes: a turning device that turns a wheel of a vehicle; a steering sensor that detects a driver's steering operation; and a control device configured to execute automated turning control that controls the turning device to automatically turn the wheel, independently of the driver's steering operation. A modification desire degree represents a degree to which the driver's steering operation modifies vehicle travel caused by the automated turning control. During execution of the automated turning control, the control device calculates the modification desire degree based on a result of detection by the steering sensor. When the modification desire degree exceeds a threshold, the control device executes system suppression processing without terminating the automated turning control. In the system suppression processing, the control device weakens the automated turning control as compared to a case where the modification desire degree is equal to or lower than the threshold.Type: GrantFiled: December 23, 2019Date of Patent: July 5, 2022Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Masaya Sato, Yoji Kunihiro, Yoshinori Watanabe, Shunsuke Tanimori, Hisaya Akatsuka
