  • Patent number: 7103461
    Abstract: A driving assist apparatus and method for a vehicle capable of guiding the vehicle at appropriate vehicle speed in accordance with the path is provided. The alarm vehicle speed for informing a driver of overspeed during driving assist is set lower for a changing steer region than for a fixed steer region. The lower alarm vehicle speed is set before the changing steer region is entered. Therefore, in the changing steer region, the vehicle speed can be sufficiently reduced, so that a set amount of steering can be accomplished. In the fixed steer region, the vehicle speed can be increased so as to reduce the time of travel.

  • Patent number: 7099758
    Abstract: A parking assist apparatus includes an initial traveling locus calculator for calculating an initial traveling locus, a new traveling locus calculating a new traveling locus when a deviation amount of the present vehicle position from a current traveling locus is equal to or greater than a first predetermined value, and a parking assist for performing a parking assist to guide the vehicle along the traveling locus. The parking assist apparatus further includes an initial traveling locus deviation calculator for calculating the deviation amount of the present vehicle position from the initial traveling locus generated by the calculation of the initial traveling locus calculator. The parking assist stops performing the parking assist when the deviation amount calculated by the initial traveling locus deviation calculator is equal to or greater than a second predetermined value which is smaller than the fist predetermined value.

  • Patent number: 7012550
    Abstract: Parking assist apparatus and method cause a vehicle driver to set a target parking position in which the vehicle is to be parked by prompting the driver to specify the position of a parking space frame in the screen of a touch display by touch-operating arrow button switches shown in the screen, and then calculate a path to the target parking position. If a path to the target parking position is not generated by calculation, the arrow button switches for moving the parking space frame in such directions that a path will not be generated (i.e., the vehicle cannot be parked), among all the arrow button switches, are made non-displayed or are displayed dimmer than the other arrow button switches, and are disabled.

  • Publication number: 20050278096
    Abstract: A driving support system according to the present invention is provided with an actuator for steering steered wheels of a vehicle and is used for supporting driving of the vehicle by making use of steering by means of the actuator. The driving support system has an image taking device for taking a forward image ahead the vehicle, a determiner for determining a controlled variable of the actuator on the basis of the forward image acquired by the image taking device, a limiter for limiting the controlled variable when a time change of the controlled variable of the actuator determined by the determiner is off a predetermined range, and a controller for controlling the actuator. The limiter sets a limit value for limiting the time change of the controlled variable of the actuator so that the limit value at a start (or at an end) of the driving support control is different from the limit value in continuation of the driving support control.

  • Publication number: 20050273261
    Abstract: 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.

  • Publication number: 20050270145
    Abstract: 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.

  • Publication number: 20050273234
    Abstract: 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.

  • Patent number: 6929082
    Abstract: 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.
