    摘要: A steering assist system for applying a steering torque reduces the influence of a time-dependent steering control amount on an assist steering torque when a predetermined driving operation by a driver is detected. Thus, the influence of the time-dependent steering control amount on the applied steering torque, which increases when the period of time over which actual moving state deviates from the target moving state increases is reduced when the driver makes the predetermined driving operation. Thus, it is possible to avoid the problem where steering feel degrades because the steering torque increases over time.

    摘要: A driving control apparatus of the present invention has a driving road keeping device for providing a torque to a steering mechanism so as to keep a vehicle traveling at a predetermined position on a driving road; a driving road departure warning device for issuing a warning of a departure from the driving road on the basis of a position of the vehicle relative to the driving road; and a setting device for setting a need or no need for execution of a control of the driving road keeping device or the driving road departure warning device. Where the setting device sets a need for execution of the control, the control of the driving road keeping device is executed when an activation condition of the driving road keeping device is met and when a cruise control device is active. Where the setting device sets a need for execution of the control, the control of the driving road departure warning device is executed when the activation condition of the driving road keeping device is not met or when the cruise control device is inactive. According to the present invention, a lane departure warning function and a lane-keep assist function are selectively executed in conjunction with activation/deactivation of the cruise control device and the activation condition of the driving road keeping device, whereby, even with an automatic stop of operation of either one of the functions, the other function can prevent the vehicle from departing from the lane.

    摘要: An apparatus for warning deviation from a lane has a deviation evaluation ECU 1. The deviation evaluation ECU 1 has a deviation evaluator 14 for performing an evaluation on a deviation by comparing a future position of a host vehicle with a lane future position. Before this deviation evaluation, a mask processor 13 determines whether a yaw angle of the host vehicle and a lateral position of the vehicle relative to a driving lane exceed their respective thresholds preliminarily determined. When either one or the both are not more than the thresholds, the mask processor 13 performs a mask process, without performing the deviation evaluation. A deviation evaluator 14 performs the deviation evaluation when the yaw angle and the lateral position relative to the driving lane both exceed their respective thresholds.

    摘要: Characteristic lines A to D of lateral acceleration G-required torque T in determination of required torque T are used as switched according to increase/decrease of the absolute value of the lateral acceleration, and the direction thereof. The lines A, C used in increase of the absolute value of the lateral acceleration G are so set that the absolute value of required torque T becomes larger at the same lateral acceleration G (G≠0) than that with the lines B, D used in decrease of the absolute value of the lateral acceleration G. The difference between line A and line B (the difference between line C and line D as well) at the same lateral acceleration G is so set that the difference near the lateral acceleration of 0 is smaller than that in the other regions. Particularly, it is preferable to set the required torque T to 0 at the lateral acceleration G of 0.

    摘要: When an integral calculation of a physical quantity representing a state of a controlled system is performed, two integral calculations, that is, a positive-integral calculation and a negative-integral calculation are performed. In this way, differentiated information can be obtained, depending on the control conditions. A selection of which one of the integral value obtained by the positive-integral calculation and the integral value obtained by the negative-integral calculation is used, is made on the basis of an actual control value and a desired control value when control is performed so that a value representing the state of the controlled system becomes equal to the desired control value. In this way, a control parameter which has been judged to include a phase delay is removed. Thus, the phase delay in the overall control can be suppressed, and an appropriate steering assist control can be performed, for example.

    摘要: A driving support system according to the present invention is provided with an actuator for steering steered wheels and performs a driving support control of a vehicle to apply an additional torque to a steering mechanism incorporating the steered wheels, by means of the actuator to steer the steered wheels. The driving support system has an image taking device for taking a forward image ahead the vehicle, a controller for driving the actuator to generate the torque on the steering mechanism on the basis of the forward image acquired by the image taking device, to perform the driving support control, a steering wheel torque detector for detecting a steering wheel torque on a steering wheel, and a control suppressor for prioritizing a steering operation by a driver to the driving support control when a magnitude of the steering wheel torque is not less than a predetermined value. The control suppressor sets the predetermined value so that the predetermined value in a case where a direction of the steering torque for the driving support control agrees with a direction of the steering wheel torque by the driver is larger than the predetermined value in a case where the direction of the steering torque does not agree with the direction of the steering wheel torque. This configuration enables the system to accurately grasp a driver's intension and to prioritize the steering operation by the driver more accurately when the steering operation by the driver should be prioritized to the driving support control.
