    摘要： An object of the present invention is to provide a steering assist device which can perform steering assist control having excellent capability to follow up a traveling path by increasing the steering amount in the steering control at a curve entrance. A steering assist device of the present invention is a steering assist device 1 for calculating a steering target value based on a shape of a traveling path on which a vehicle travels, and assisting steering according to the steering target value, wherein it is determined whether the vehicle is traveling a curve entrance of the traveling path, and when it is determined that the vehicle is traveling a curve entrance, a change in the steering target value is increased compared with the case of traveling a part of the path other than a curve entrance. As a result, a steering amount to turn the steering wheel can be increased at a curve entrance, and a delay in the turning of the steering wheel at a curve entrance can be suppressed.

    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： Lane width information Winf acquired by a traffic lane detector is retrieved (step S1); when a value of the lane width information Winf is within a predetermined range of change amount relative to a lane width output Wout_old at a previous time step, i.e., not less than (Wout_old+Wdec) nor more than (Wout_old+Winc), Winf is used directly as the lane width output Wout (steps S5→S9→S11→S8); when the value of lane width information Winf is off the predetermined range, i.e., less than (Wout_old+Wdec), (Wout_old+Wdec) is outputted as the lane width output value Wout (steps S5→S9→S10→S8); when the value of lane width information Winf exceeds (Wout_old+Winc), (Wout_old+Winc) is outputted as the lane width output Wout (steps S5→S6→S8).

    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： 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.
