Abstract: A behavior control system includes: a behavior control device for changing a behavior of a moving body; an imaging device for acquiring images ahead of the moving body; and a control device for controlling the behavior of the moving body based on the images acquired by the imaging device. The control device includes: a feature point extraction unit configured to extract feature points from the images acquired by the imaging device; a straight moving state storing unit configured to store, as a reference feature point state, a feature point state when the moving body is in a straight moving state, the feature point state being obtained based on a temporal change of the feature points; and a moving body control unit configured to control the behavior control device when the feature point state obtained based on the temporal change of the feature points differs from the reference feature point state.

Abstract: Path generation apparatus configured to generate target travel path of own vehicle traveling in travel lane, includes: external sensor mounted on own vehicle and configured to detect external situation centered on advancing direction of own vehicle; vehicle speed sensor configured to detect travel speed of own vehicle; and electronic control unit including processor and memory coupled to processor. Electronic control unit is configured to perform: setting target passing point on travel lane based on external situation; and generating target travel path from current location point of own vehicle to target passing point. Setting target passing point includes setting target passing point after predetermined time period when travel speed is equal to or higher than predetermined value, while setting target passing point to predetermined distance ahead from current location point when travel speed is lower than predetermined value.

Abstract: A vehicle running control device including: a vehicle speed sensor which detects an actual vehicle speed; a target vehicle speed setting unit; a target drive force calculation unit; a drive force control unit; a vehicle speed lowering allowance value setting unit; and a target drive force upper limit calculation unit. If the actual vehicle speed lowering amount with respect to the target vehicle speed is within the lowering allowance value, the target drive force calculation unit limits the target drive force to be not greater than the target drive force upper limit and the drive force control unit executes drive force control in accordance with the limited target drive force.

Abstract: A travel speed limiting apparatus including: a travel speed measurement device which measures a travel speed of a vehicle; a speed limit memory device which stores a speed limit set by an operator; a first driving force limit value calculation device which calculates a first driving force limit value based on a deviation of the travel speed from the speed limit; a requested driving force calculation device which calculates a requested driving force based on an operator's acceleration operation; and a second driving force limit value calculation device which calculates a second driving force limit value based on the requested driving force, wherein the driving force limiting device sets an eventual driving force limit value to the smaller of the first driving force limit value and the second driving force limit value, and controls the driving force of the vehicle to be less than the eventual driving force limit value.

Abstract: In a control system for an internal combustion engine having a plurality of cylinders and mounted on a vehicle, in which the engine operation is switched based on the throttle opening between a full-cylinder operation in which all of the cylinders are operative and a cut-off cylinder operation in which some of the cylinders are inoperative, and a running control including a cruise control in which the vehicle runs at a desired vehicle velocity and a preceding vehicle follow-up control in which the vehicle runs at a desired vehicle velocity to maintain a desired inter-vehicle distance from a preceding vehicle are conducted. In the system, an acceleration suppression control is conducted if the engine operation is switched from the cut-off cylinder operation to the full-cylinder operation when the running control is in progress. With this, sharp or drastic acceleration accompanying torque fluctuation is effectively avoided, when the engine operation is switched to the full-cylinder operation.

Abstract: In a control system for an internal combustion engine having a plurality of cylinders and mounted on a vehicle, in which the engine operation is switched based on the throttle opening between a full-cylinder operation in which all of the cylinders are operative and a cut-off cylinder operation in which some of the cylinders are inoperative, and a running control including at least a cruise control in which the vehicle runs at a desired vehicle velocity is conducted, the engine operation is switched to the full-cylinder operation when it is determined that deceleration is required in the running control, so as to increase pumping loss (engine loss). With this, it becomes possible to generate the deceleration sufficiently as desired, when, for example, the vehicle descends a downhill.
