Publication number: 20170259817Abstract: A travel control apparatus for a vehicle includes a travel environment information acquisition unit, a travel information detection unit, and a control unit. The acquisition unit acquires travel environment information of the vehicle, which is on a traveling environment of the vehicle. The detection unit detects travel information of the vehicle. The control unit performs self-driving control, on the basis the information. The control unit detects a relative distance between an oncoming vehicle and the vehicle, and performs turn control to cause the vehicle to make a turn while crossing ahead of the oncoming vehicle, in a case where the relative distance is not smaller than a preset threshold value. When the vehicle makes the turn, in a case where a traction control for preventing tire slippage by decreasing a drive torque is operated, the control unit increasingly corrects the preset threshold value in accordance with at least a tire grip state.Type: ApplicationFiled: February 8, 2017Publication date: September 14, 2017Inventor: Harunobu HORIGUCHI

Patent number: 9637107Abstract: In a travel control apparatus for a vehicle, a travel environment information acquisition unit acquires travel environment information on a travel environment of the vehicle. A travel information detector detects travel information on the vehicle in order to execute automatic driving control based on such information pieces. A lateral force generator generates lateral force to be applied to the vehicle during the automatic driving control. A torsion bar is interposed on a torque transmission path of a steering system. A steering wheel angle detector detects a steering wheel angle. A lateral force detector detects the lateral force acting on the vehicle. An intervening steering operation determination unit determines that a driver has performed an intervening steering operation when a characteristic of the detected steering wheel angle and lateral force differs from a reference characteristic that varies univocally when the steering wheel is in a no load condition.Type: GrantFiled: November 6, 2015Date of Patent: May 2, 2017Assignee: FUJI JUKOGYO KABUSHIKI KAISHAInventors: Koji Matsuno, Satoru Akiyama, Takayuki Nagase, Eiichi Shiraishi, Shiro Ezoe, Hajime Oyama, Yasushi Takaso, Masato Mizoguchi, Harunobu Horiguchi
