To enable calling and turning off of failure codes stored in a control unit without using a dedicated switch or the like. An electronic control unit controls an actuator of a braking device, stores failure codes representing problems in the braking device, and has its power terminal connected to a battery via a fuse. A main switch is turned on to connect the power terminal to the battery. Thereafter, the fuse is made inoperative or detached, and is re-installed after a lapse of a predetermined time interval. A failure code stored in the electronic control unit is called, and is displayed by an indicator. Then, the fuse is again made inoperative or detached, and re-installed in the predetermined time interval. The failure code will be automatically turned off. Alternatively, a connector may be used to substitute for or in combination with the fuse.

An airbag apparatus for a motorcycle includes an airbag module with an airbag that is capable of being inflated and deployed so as to restrain the rider on a seat disposed behind the fuel tank from the front that is mounted on the vehicle body frame. Without requiring a modification of the configuration of the appearance constituting parts of the motorcycle, water, mud, or the like is prevented from breaking into the airbag module. The front portion of the seat that covers the airbag module to be mounted on the vehicle body frame at a position rearwardly of the fuel tank from above and extends to the position on the rear portion of the fuel tank is constructed so as to be opened with the rear side raised upwardly in response to inflation and deployment of the airbag.
摘要:
To provide a method and an apparatus for controlling a gear-shift of a motor-driven gear shifter in which the gear-shift is electrically performed by a motor. In particular, the present invention relates to a method and an apparatus for detecting a rotational position of a shift drum, when the shift operation is not normally ended, and thereby a shift drum is in the half-neutral state, which automatically executes the shift operation. In the method for controlling the gear-shift of the motor-driven gear shifter, the motor is driven in a desired shift direction, to intermittently turn a shift drum, thereby shifting one gear stage to another gear stage. The rotational position of the shift drum is monitored, and when the shift drum stays at a rotational position other than a rotational position corresponding to a desired gear stage, the motor is re-driven in the shift direction.

To provide a continuously variable transmission for motor vehicles which transmits power with a speed change from a driving member to a driven member. In the continuously variable transmission, power transmission is effected by moving a carrier which supports a shifting rotating member in frictional contact with the driving member and the driven member. No other special mechanism other than the continuously variable transmission is needed to push to move the motor vehicle with a small force. At least either one of the driving member and the driven member is driven by a power disconnecting means to move away from the other member along the axis of a transmission shaft, thereby releasing at least one of the driving member and the driven member from frictional contact with the first and second friction transfer surfaces.

An air bag, a control device and a rider or operator removal detecting part are disposed in an operator's jacket. An air bag device body includes air inflating chambers, an ECU, a battery, a radio receiver, a main switch and a warning device incorporated into the jacket. In response to a synchronizing signal transmitted from a vehicle-body-side radio transmitter, a vehicle-body-side electric wave signal generating part and a rider-side reference waveform signal generating part, respectively, generate an electric wave signal and a comparison signal in a synchronized state with a signal comparing part determining a phase difference between both signals. When a delay quantity or a change of the delay quantity of the electric wave signal from the electric wave signal generating part is increased, the ECU detects a removal of a rider for informing an air bag drive part.

To provide a clutch connection control system capable of shortening the time required for clutch connection, preventing the degradation of riding comfort upon clutch connection, and ensuring good operability. A separation distance, that is, a shift amount of a clutch driven side from a clutch drive side is controlled by a clutch release mechanism driven by a drive motor. A drive side turning speed detecting portion detects a turning speed Nin of the drive side. A driven side turning speed detecting portion detects a turning speed Nout of the driven side. A turning speed difference detecting portion detects a difference Nd between the detected drive side turning speed Nin and driven side turning speed Nout. A rate-of-change detecting portion detects a time-dependent rate of change &Dgr;Nd of the detected turning speed difference Nd. A control portion performs clutch connection at a first speed until the time-dependent rate of change &Dgr;Nd becomes a specific value or less and performs clutch connection at a second speed lower than the first speed after the time-dependent rate of change &Dgr;Nd becomes the specific value or less.
