First Claim
1. A device for setting steering characteristics of an electric power steering system, comprising:
- a steering characteristics diagram selection means for selecting a plurality of steering characteristics diagrams prepared in relation with steering conditions;
a steering characteristics diagram display means for displaying a steering characteristics diagram selected by the steering characteristics diagram selection means;
a steering characteristics diagram compilation means for compiling while observing the steering characteristics diagram so as to achieve an optimum steering feeling in accordance with a driver'"'"'s taste and tendencies or running conditions of a vehicle;
a storage means for storing a steering characteristics diagram thus compiled;
a steering characteristics diagram reading means for reading the steering characteristic diagram stored in the storage means; and
an electric power steering driving motor control means for assisting the steering operation according to a driving signal generated on a basis of the steering characteristics diagram thus read.

Abstract
The optimum value of steering feelings in operating an electric power steering system depends on a vehicle model, changes in vehicle model characteristics, payload and driving conditions by secular changes, and the driver'"'"'s preferences. A steering characteristics diagram selected by a steering characteristics diagram selection means is compiled by the use of a mouse on a display in accordance with a driver'"'"'s tastes and tendencies, and vehicle driving conditions. An EPS (electric power steering) controller and an EPS driving motor are controlled by the steering characteristics diagram thus compiled, thereby assisting the steering operation. A driver can grasp the necessary amount of compilation as an intuitive amount while observing the steering characteristics diagram on a display. The driver may easily and rapidly reset a variety of steering feelings suited to the driver'"'"'s personality in accordance with his tastes and tendencies, and the vehicle driving conditions.
