Title: Running control device
Inventor: SUGANO TAKESHI
IPC: F02D29/02
Filed: 2003-04-17
Abstract: <P>PROBLEM TO BE SOLVED: To provide a running control device capable of avoiding the situation where a greater acceleration/deceleration acts owing to the running control for keeping the inter-vehicle distance to the foregoing vehicle to the target value in the condition where a relatively large sideways wind pressure is applied or the vehicle is running on a rail-laid road surface, and the behavior of the vehicle becomes unstable.  <P>SOLUTION: When a turbulence in the transverse direction is sensed, for example in the condition that the wind pressure is large or the vehicle is running on the rail-laid road surface (Step S2), the natural frequency ωn to decide the convergence characteristic of the inter-vehicle distance to the target value is corrected in the direction of making the convergence characteristic more gradual (Step S8 and S12), and if the situation is under deceleration, the degree of correction is made smaller than in acceleration, and such a tendency is avoided as approaching the foregoing vehicle too much owing to suppression of the degree of decelerating during deceleration. Because the correction of the natural frequency ωn suppresses the acceleration/deceleration, it is possible to avoid acting of a relatively large acceleration/deceleration in the condition that a sideways turbulence is applied and the vehicle behavior is likely to become unstable.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
