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.
摘要翻译： 当检测到驾驶员的预定驾驶操作时，用于施加转向转矩的转向辅助系统减小了与时间有关的转向控制量对辅助转向转矩的影响。 因此，当驾驶员进行预定的驾驶操作时，当实际移动状态偏离目标移动状态的时间段增加时，随着时间的转向控制量对所施加的转向转矩的影响减小。 因此，可以避免由于转向扭矩随时间增加而导致转向感觉下降的问题。

摘要： A vehicle speed V is compared with a threshold Vth; when V is less than Vth, TLC is set to an initial value t0; when V is not less than Vth, TLC is set shorter with increase in V. Then TLC is compared with a predetermined value t th, and when TLC is less than t th, TLC is replaced by t th being a lower limit. This improves compatibility between a reduction in an occurrence frequency of needless warnings and a guarantee of a deviation margin 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： In a driving assistance system having an actuator (16) for steering steered wheels of a vehicle, a positional deviation detecting unit (9) detects a deviation of a position of the vehicle from a forward travel path of the vehicle based on information around the vehicle. A steering control variable determination unit (2) determines a steering control variable to cancel the deviation. If a vehicle speed detected by a vehicle speed detecting unit is equal to or greater than a predetermined speed, the steering control variable determined by a steering control variable determination unit (2) decreases with an increase of the vehicle speed under the condition that the deviation of the position of the vehicle from the forward travel path is same. The driving assistance system can reduce a driver's discomfort caused by the steering control through the actuator (16) when the vehicle is running at a high speed.

摘要： A vehicle speed V is read (step S1), V is compared with a first threshold Vth1 (step S2), and, when V is not less than Vth1, a warning torque is set smaller with increase in V (step S3). When V is less than Vth1, V is further compared with a second threshold Vth2 (step S4), and when V is less than Vth2, the warning torque is set approximately in proportion to the vehicle speed (step S5); when V is not less than Vth2 and is less than Vth1, the warning torque is set at a predetermined constant value (step S6).

摘要： In deviation prevention support ECU 10 in driving operation support system 1, an applied torque by steering torque applier 17 is set based on a vehicle speed of a vehicle. The applied torque is set to increase with increase of the vehicle speed. An upper limit according to the vehicle speed is set for this applied torque. Furthermore, in a Start interval in application of the applied torque, a rate of increasing to reach a maximum is determined according to the maximum of the applied torque. In a Close interval, the applied torque is decreased at a rate different from that in the Start interval, and the absolute rate of increasing the torque in the Start interval is set to be larger than the absolute rate of decreasing the torque in the Close interval.
