A two-wheeled motorcycle having a frame carrying a drive motor, a radio, a servo mechanism controlled by the radio, and a power source for driving the motor, radio, and servo. The servo mechanism includes a weight which may be moved to one side or the other of a generally vertical plane extending through the motorcycle when it is in an upright position. The steering crown is arranged so that a plane including the axes of the down tube and the fork is behind the main pivot. The axle of the front wheel is in the plane of the fork axes. The plane including these axes intersects the surface upon which the motorcycle rests at an angle in the range of about 20.degree.-25.degree. relative to vertical. The arrangement of the steering crown is such that, when the servo moves the weight to one side of the generally vertical plane, the front wheel will tend to turn into the direction in which the weight is moved. This is accomplished by insuring that the plane including the axes of the down tubes and forks are behind, but parallel to, the pivot axis of the crown, relative to the frame.

Directional controller 24 generates control signals for guiding the vehicle to the left or right while the acceleration trigger 22 generates control signals for controlling the speed of the vehicle. Transceiver antenna 48 allows for increasing the range of the signal transmitted to the receiver/servo unit 42 and thus the range at which the vehicle 10 may travel from the remote control unit 20. Upon toggling Enable/Disable switch 26 a second time to the enable position control of the toy vehicle is re-enabled.
FIG. 8 is an illustrative view of the remote control transmitter of the child-rideable motorized vehicle 10 of the present invention in use. The child-rideable motorized vehicle 10 is a 4×4 vehicle having tires 16, shown in FIG. 1, providing stable movement. Although a 4×4 vehicle is preferred in an optimal embodiment, in practice the vehicle can be of any type with any number of tires. The child-rideable motorized vehicle 10 of the present invention may be used in a manual mode or a remote override mode.
The child-rideable motorized vehicle 10 of the present invention, as shown in FIG. 3, may be used in a manual mode or a remote override mode. The remote control unit 20, as shown herein, is used to operate the child-rideable motorized vehicle 10 in remote override mode. The remote control unit 20 includes Enable/Disable switch 26, acceleration trigger 22, directional controller 24 and transceiver antenna 48. Remote override mode is entered upon activation of Enable/Disable switch 26. Once remote override mode is enabled manual control of the toy vehicle is disabled. The remote override mode provides for control of the vehicle by directional controller 24 and acceleration trigger 22. Acceleration of the vehicle is controlled by the intensity of the user/parent 14's squeezing of the acceleration trigger 22. The vehicle is guided left and right by the user/parent 14's turn of directional controller 24. Transceiver antenna 48 increases the range of the signal transmitted to the receiver/servo unit 42 shown in FIG. 3. Upon toggling Enable/Disable switch 26 a second time to the enable positions control of the toy vehicle is re-enabled.
FIG. 9 is a block diagram of the remote control unit of the child-rideable motorized vehicle 10 of the present invention in remote override mode. Remote control transmitter 20 communicates with child-rideable motorized vehicle 10 to toggle between a manual mode and a remote override mode. Switches 200, 210 and 220 connect to system controller and range detector 110. When receiver 50 receives a signal indicating a toggle into remote override mode, switches 210 and 220 are caused to move from a first open position to a second closed position creating a transmission path for messages through system controller with range detector 110. In remote override mode manual controls are disabled, therefore switch 200 is caused to move from a second closed position to a first open position in remote override mode.
The system controller with range detector unit 110 is powered by battery 40. System controller 110 transmits control signals from the receiver 50 to servo control unit 130. Range detector 110 detects the distance from the remote control transmitter 20 to the remote enabled motorized toy 10. When the remote enabled motorized toy 10 exceeds a predetermined distance a signal is sent to servo control unit 130 to stop the vehicle.
Servo control unit 130 receives steering control signals and acceleration control signals from either system controller with range detector 110 or operator control 120. Accordingly servo control unit 130 includes a steering control actuator 140 and an acceleration control actuator 150. Steering control signals, indicating a desired turn of the front tires to the left or right, are processed by steering control actuator 140. Steering control actuator 140 then sends either a servo motor right signal 160 or a servo motor left signal 170 to steering servo motor 44 shown in FIG. 5. Acceleration control signals, indicating the desired speed of the vehicle 10, are processed by acceleration control actuator 150. Acceleration control actuator 150 then sends a rear servo motor signal 180, indicating a control speed, to rear servo motor 30, shown in FIG. 4.
FIG. 10 is a block diagram of the remote control unit of the child-rideable motorized vehicle 10 of the present invention in manual mode. Remote control transmitter 20 communicates with child-rideable motorized vehicle 10 to toggle between a manual mode and a remote override mode. Switches 200, 210 and 220 connect to system controller and range detector 110. In manual mode remote controls are disabled, therefore switches 210 and 220 are caused to move from a second closed position to a first open position disestablishing a transmission path to the servo controller unit 130 through system controller 110. Switch 200 is caused to move from a first open position to a second closed position to provide power from battery 40 through system controller 110.
Operator control 120 transmits controls signals from manual controls 18 shown in FIG. 1 to servo control unit 130. Range detector 110 detects the distance from the remote control transmitter 20 to the remote enabled motorized toy 10. When the remote enabled motorized toy 10 exceeds a predetermined distance a signal is sent to servo control unit 130 to stop the vehicle.
Servo control unit 130 receives steering control signals and acceleration control signals from either system controller with range detector 110 or operator control 120. Accordingly servo control unit 130 includes a steering control actuator 140 and an acceleration control actuator 150. Steering control signals, indicating a desired turn of the front tires to the left or right, are processed by steering control actuator 140. Steering control actuator 140 then sends either a servo motor right signal 160 or a servo motor left signal 170 to steering servo motor 44 shown in FIG. 5. Acceleration control signals, indicating the desired speed of the vehicle 10, are processed by acceleration control actuator 150. Acceleration control actuator 150 then sends a rear servo motor signal 180, indicating a control speed, to rear servo motor 30, shown in FIG. 4.
