Abstract: In order to improve the maneuver performance of the electrical vehicles so as to realize spot reeling at any point of the body and motion in any direction, a design scheme was put forward for spot steering of electric vehicle by making use of in-wheel motor and out motor. This scheme adopted biasing kingpin double wish-bone suspension oriented framework and bevel gear by wire steering system. Through making the backup of steering_motor and switch machine, the reliability of the entire steering system was greatly improved. In addition, by adopting Virtual Prototype Technology, according to wheel alignment parameter, the entire parameterized model in circumstance of ADAMS software was created and meanwhile the suspension guiding mechanism was optimized.

Key words: steering by wire, double wish-bone suspension, in-wheel-motor
