1. A steering system for a vehicle having a steerable front wheel and a steerable rear wheel, comprising:
- a front wheel steering mechanism for steering said front wheel;
a rear wheel steering mechanism for steering said rear wheel in accordance with a travelling state quantity substantially influenced by a disturbance; and
said rear wheel steering mechanism including;
actuating means for actuating said rear wheels;
first detection means for detecting said travelling state quantity;
second detection means for detecting a vehicle'"'"'s speed of said vehicle;
control means connecting to said first and second detection means and adapted to provide a control signal for said actuating means;
said control means having an operation process means for determining a provisional steering quantity of said rear wheel depending on an output signal of said first detection means through a predetermined expression of function, a correction factor corresponding to said vehicle speed from an output signal of said second detection means, and a final steering quantity of said rear wheel based on said predetermined expression of function and said correction factor, and for producing said control signal representing said final steering quantity; and
said correction factor decreases as said vehicle speed decreases.
