Patent ID: 7303459

Claim:
A toy system comprising: a pair of driving sources for individually generating driving forces on right and left sides of a moving body; an operating device having a throttle portion operating to direct a velocity of said moving body and a steering portion operating to direct an advancing course of said moving body, and capable of outputting a signal corresponding to operation states of said throttle portion and said steering portion; a driving control device controlling driving velocities of each of the pair of driving sources such that the driving velocities of said pair of driving sources are increased or decreased in association with an operation amount of said throttle portion, and, when said steering portion is operated from a predetermined neutral position, a difference occurs between the driving velocities of said pair of driving sources at a velocity ratio which is defined as a value obtained by dividing the driving velocities of the driving sources at a low velocity side by the driving velocities at a high velocity side, in association with the operation amount of the steering portion; a setting device accepting a setting operation inputting setting values setting a predetermined parameter defined as an item to give an influence on an ease of turning said moving body by a user; and a storing device for storing plural kinds of data pieces for specifying a relationship between said operation amount of said throttle portion and said velocity ratio when said operation amount of said steering portion is a predetermined reference value, so as to be associated with each of the setting values setting said predetermined parameter as set by the setting operation, wherein: a data piece for specifying the relationship between said operation amount of said throttle portion and said velocity ratio generated when said operation amount of said steering portion is the predetermined reference value is constituted such that said velocity ratio corresponding to said reference value becomes larger as said operation amount of said throttle portion is increased, and said driving control device selects a data piece corresponding to the setting value of said parameter among said plural kinds of data pieces, which are stored in said storing device, and with reference to a relationship between said reference value and said velocity ratio, which is specified by the selected data piece, changes a correspondence relationship between said operation amount of said steering portion and said velocity ratio such that said pair of driving sources are driven at a velocity ratio corresponding to said reference value when said operation amount of said steering portion reaches said reference value, and said velocity ratio becomes smaller as said operation amount of said steering portion is increased.
