20080208409 | VEHICLE DYNAMICS CONTROL APPARATUS - In a vehicle dynamics control apparatus capable of balancing a vehicle dynamics stability control system and a lane deviation prevention control system, a cooperative control section is provided to make a cooperative control between lane deviation prevention control (LDP) and vehicle dynamics stability control (VDC). When a direction of yawing motion created by LDP control is opposite to a direction of yawing motion created by VDC control, the cooperative control section puts a higher priority on VDC control rather than LDP control. Conversely when the direction of yawing motion created by LDP control is identical to the direction of yawing motion created by VDC control, a higher one of the LDP desired yaw moment and the VDC desired yaw moment is selected as a final desired yaw moment, to prevent over-control, while keeping the effects obtained by both of VDC control and LDP control. | 08-28-2008 |
20110015850 | LANE KEEPING ASSIST DEVICE AND LANE KEEPING ASSIST METHOD - Lateral displacement reference positions LXL, LXR are set on left and right from a center in a width direction of a traffic lane L where a vehicle travels. Then, at least in a case where the vehicle is positioned on an inner side of the left and right lateral displacement reference position LXL, LXR, the vehicle is feedback-controlled so as to decrease a yaw angle deviation. Further, in a case where the vehicle is positioned at an outer side of the left and right lateral displacement reference position LXL, LXR with respect to the traffic lane center, the feedback control is performed so as to decrease the angle deviation and a lateral displacement deviation. | 01-20-2011 |

20100222958 | VEHICLE DRIVING OPERATION SUPPORT APPARATUS/PROCESS AND RESTRAINT CONTROL - A vehicle driving operation support apparatus for a vehicle, includes a sensing section to sense a traveling condition of the vehicle including a surrounding condition inclusive of an obstacle around the vehicle, and a control section to calculate a risk potential for the vehicle in accordance with the traveling condition. The control section performs a support control to support the driver in accordance with the risk potential, and performs an assist control to restrain disturbance (such as vibration from a road) transmitted to the driver in accordance with the risk potential. | 09-02-2010 |
20100222959 | VEHICLE DRIVING OPERATION SUPPORT APPARATUS/PROCESS AND INDUCEMENT CONTROL - A vehicle driving operation support apparatus for a vehicle, includes a sensing section to sense a traveling condition of the vehicle including a surrounding condition inclusive of an obstacle around the vehicle, and a control section to calculate a risk potential for the vehicle in accordance with the traveling condition. The control section performs a support control to support the driver in accordance with the risk potential and performs an assist control to produce inducement simulating a condition change (such as a vehicle behavior) attributable to an increase of the risk potential, in accordance with the risk potential. | 09-02-2010 |
20100222960 | VEHICLE DRIVING OPERATION SUPPORT APPARATUS/PROCESS AND COOPERATION CONTROL - A vehicle driving operation support apparatus for a vehicle, includes a sensing section to sense a traveling condition of the vehicle including a surrounding condition inclusive of an obstacle around the vehicle; and a control section to calculate a risk potential for the vehicle in accordance with the traveling condition. The control section performs a support control to support the driver in accordance with the risk potential, performs a first assist control to restrain disturbance (such as vibration from a road) transmitted to the driver in accordance with the risk potential, and performs a second assist control to produce inducement simulating a condition change (such as a vehicle behavior) attributable to an increase of the risk potential, in accordance with the risk potential. The control section further performs a cooperation control to coordinate the first assist control and the second assist control. | 09-02-2010 |
20100222965 | VEHICLE DRIVING OPERATION SUPPORT APPARATUS/METHOD AND VEHICLE - A motor vehicle includes a vehicle driving operation support system. The vehicle driving operation support system senses an environment surrounding the motor vehicle; senses a traveling condition of the motor vehicle; calculates a risk potential of the motor vehicle on a basis of the sensed environment and the sensed traveling condition; controls the motor vehicle on a basis of a control setpoint. The vehicle driving operation support system sets on a basis of the calculated risk potential the control setpoint to a provisional setpoint effective for reducing the risk potential; senses driver's operation in reaction to the controlling operation with the control setpoint set to the provisional setpoint; and sets the control setpoint to a normal setpoint on a basis of the sensed driver's operation. | 09-02-2010 |
20110004387 | VEHICLE HEADWAY MAINTENANCE ASSIST SYSTEM AND METHOD - A vehicle headway maintenance assist system is provided that provides a haptic notification to an accelerator to alert the driver under prescribed conditions. The vehicle headway maintenance assist system includes a preceding vehicle detection section, a reaction force generating section, and a control section. The preceding vehicle detection section is configured to detect a headway distance between a host vehicle and a preceding vehicle. The reaction force generating section is configured to generate a reaction force based on the headway distance detected by the preceding vehicle detection section. The control section is configured to control a relationship between a driving force and an accelerator actuation amount by a driver to increase the accelerator actuation amount at a time before the reaction force generating section generates the reaction force. | 01-06-2011 |
