Abstract:
A lean detector for a vehicle is capable of reducing the cost of the parts of a lean sensor and enhancing the waterproof property thereof. The lean detector also detects when the leaning of the vehicle body has reached a prescribed angle in the right, left, front or rear direction. The lean sensor is installed at a position above a bottom end of a baseplate of the seat of a saddle-ride type four-wheeled vehicle.
Abstract:
A versatile GPS-equipped meter includes a GPS antenna and a GPS processing circuit in an existing meter unit. Posture adjusting members are provided that have different shapes according to an attachment angle θ of a GPS-equipped meter to a vehicle body frame are appropriately selected so as to point a GPS antenna to the sky regardless of the attachment angle θ. In a meter case, an antenna relief part is secured. Accordingly, even if a relative positional relationship between the meter case and the GPS antenna is changed due to a change in the shape of the posture adjusting member, the meter case and the GPS antenna never interfere with each other. Thus, the GPS-equipped meter can be shared with various vehicles without increasing the meter case in size. Therefore, the versatility is improved.
Abstract:
In a personal watercraft with a watercraft body including a hull forming a bottom portion and a deck covering the hull from above, a magnet box is integrally combined with a battery storage tray. The watercraft also includes an engine disposed within the watercraft body, and a saddle-type seat disposed above the engine. A magnet box, including a main box body and a lid member, sealingly stores an electromagnetic starter switch therein, and is disposed in front of a battery storage tray, in order to reduce the distance between the magnetic starter switch and a starter motor. The main box body is formed integrally with a battery storage tray which is disposed in back of the engine and fixedly disposed on a floor portion of the watercraft body. The lid member is adapted to sealingly close the main box body of the magnet box in a fluid-tight manner.
Abstract:
An electronic key system for a vehicle provides a warning corresponding to a traveling state if an occupant has dropped the electronic key while a vehicle is running. A control unit 14 of the vehicle outputs a request signal Sr to the electronic key 12 at transmission intervals T corresponding to the traveling state. An answer signal Sa caused by the request signal Sr from the electronic key 12 is detected. A warning lamp 68 is lit up at a point after the detection of the answer signal Sa stops. The transmission interval T of the request signal Sr is specified in a map 88 stored in the control unit 14, and is set short corresponding to the increase of the vehicle speed V, the acceleration/deceleration ‘a’, and the yaw rate Y.
Abstract:
An electronic key system 100 for a moving body, for example an all-terrain vehicle 10, includes an electronic key 11 and a control unit 50. The electronic key 11 transmits a control code Md stored in a ROM 76. The control unit 50 reads a speed limit Vs and a power limit Ws out of one of first to fourth control mode data Md1 to Md4, which corresponds to the received control code Md, and supplies the limits to a drive control performing section 104. The drive control performing section 104 controls an engine 22 in accordance with the speed limit Vs and the power limit Ws to limit a travel speed V and power W. This renders the driving performance appropriate to the driving condition and/or the driver.
Abstract:
To provide a vehicle navigation system that can accurately display a position of a vehicle that has the navigation system mounted thereon and a target direction even when the vehicle is stopped or traveling at low speed. The vehicle navigation system includes a device that senses a traveling state of a vehicle, a device that judges whether or not the vehicle is stopped or traveling at a low speed, and a device that smoothes GPS positioning data so that error components contained in the GPS positioning data are canceled out or compensated for when the vehicle is stopped or traveling at a low speed. The navigation system further includes a device that calculates the current position based on the smoothed GPS positioning data. The smoothing device outputs new positioning data, for example, based on current GPS positioning data and previous GPS positioning data.

Abstract:
A GPS-based vehicle navigation system and method for properly displaying direction guide information, which represents a target direction, regardless of forward motion or backward motion. The system calculates the current position of the vehicle, and senses the traveling direction of the vehicle. The operation mode of the system is determined. If the operation mode is a “compass mode”, the orientation of the traveling direction is calculated based on the current position and the traveling direction. On the other hand, if the operation mode is a “NAVI mode”, a target position T separately set is read, and a target direction is calculated based on the current position and the target position T. Next, it is determined whether the motion of the vehicle is forward or backward. If the motion of the vehicle is backward, the direction guide information is corrected by an angle equivalent to 180°.
Abstract:
A jet propulsion boat is equipped with a liquid crystal display unit displaying operation information. An ordinary movement of the jet propulsion boat is regarded as an ordinary state. When the need arises for abruptly reducing the speed of the transportation means or abruptly changing the direction of the transportation means, and the like it is regarded as a non-ordinary state. The liquid crystal display unit is caused to reverse a white-and-black display thereof when the jet propulsion boat shifts from the ordinary state to the non-ordinary state. It is possible to sensitively and directly notify the driver that the transportation means is in a non-ordinary state. As a result, it becomes easier to recognize that the jet propulsion boat is in a non-ordinary state.
