摘要:
In a parking assist apparatus that assists with moving, by automatic steering, a vehicle from an arbitrary stopping position to a target parking position set by the driver, a setting portion (i.e., a parking assist ECU) sets both a path from the stopping position to the target parking position and a steering operation necessary to bring the vehicle along that path. When this path cannot be set with the steering angle in the stopping position set as the initial steering angle, and when the path can be set with another steering angle as the initial steering angle, an instruction portion (i.e., a monitor or a speaker) instructs the driver to turn the steering wheel to this other steering angle.

The present invention aims at providing a steering assistance apparatus which can accurately detect a curve exit of a running path and perform steering assistance control with an excellent running path following capability. The steering assistance apparatus of the present invention is a steering assistance apparatus 1 for providing a steering mechanism with a steering torque such that a vehicle runs along a running path according to an image capturing the running path in front of the vehicle, which estimates a curve direction of the running path by processing the image, estimates a steering direction of a driver of the vehicle according to a steering operation of the driver, and determines that the vehicle is running through a curve exit according to a fact that the estimated curve direction and steering direction do not coincide with each other. This makes it possible to determine the curve exit of the running path accurately and perform appropriate steering assistance control.

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.

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.

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 setting device for setting a need or no need for execution of a control of the driving road keeping device, and a cruise control device for controlling a driving force or speed of the vehicle so as to keep the vehicle in a predetermined driving state. A need or no need for execution of the control of the driving road keeping device is determined based on a setting state of the setting device and a control state of the cruise control device. A display indicating that the control of the driving road keeping device is ready is presented when the control of the driving road keeping device is in an executable state upon a state change of either the setting state of the setting device or the control state of the cruise control device. Therefore, with the display indicating the ready state, a driver can initiate the control of the driving road keeping device by changing the setting state of the setting device or the control state of the cruise control device in accordance with the content of the display.
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.

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.

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.

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.
