Abstract:
A control device for a creep speed advance and creep speed backing up of an electric vehicle. A mode switch provided with an operating section can be operated in a longitudinal direction and can be operated leftward from an intermediate part. The operating section is automatically returned to a stop position in which a speed zero instruction is output to a motor when not being operated by return springs. When the operating section is pushed forward, a creep speed advance mode can be selected and when the operating section is pulled backward, a creep speed backing up mode can be selected. To clearly discriminate a position of the operating section among the creep speed advance mode, the creep speed backing up mode and a normal mode, a stopper is arranged between the stop position and the normal mode so that larger force is required to operate the operating section.
Abstract:
A human body communications transmitter is provided to a vehicle body, for transmitting an activation signal by using the human body of a rider as a transmission path on the basis of an instruction from an on-vehicle ECU. A human body communications receiver is provided to an airbag jacket for receiving the activation signal which is transmitted by using the human body of the rider as the transmission path. The in-jacket ECU inflates and thus deploys the airbag jacket upon receipt of the activation signal for the airbag jacket through either human body communications or radio communications. The human body communications transmitter is connected to a right handlebar portion electrode, a left handlebar portion electrode, a seat portion electrode, a right footrest portion electrode and a left footrest portion electrode. The human body communications receiver is connected to an in-jacket electrode adjacent to the human body.

To enable a trouble diagnosis of braking-input-side pressure sensors even in a state where a braking input side and a braking output side are interrupted from each other. In a brake device of a vehicle in which a braking input side which generates a liquid pressure by manipulating a brake manipulation portion and a braking output side which supplies the liquid pressure to a brake caliper are made to be communicated with each other or being interrupted from each other by way of a first electromagnetic open/close valve, and the brake device includes a hydraulic modulator which adjusts the liquid pressure of the braking output side by operating an electrically-operated motor, the brake device includes a first pressure sensor and a second pressure sensor for detecting the liquid pressure of the braking input side, and a trouble diagnosis of the pressure sensors is performed in response to detection values of the pressure sensors.
Abstract:
The invention improves the driveability of a vehicle by controlling a target engine speed according to an engine load and a vehicle running condition to ensure an actual engine speed. In controlling a speed ratio of a continuously variable transmission, an adaptation factor is used for deciding a target engine speed, the adaptation factor is determined according to constants, an average engine load and an average vehicle speed change quantity. Even when the average engine load changes because of fluctuation in an accelerator opening, various running modes can be decided by the adaptation factor depending upon both the average engine load and the average vehicle speed change quantity, thereby improving driveability upon changing speed of the continuously variable transmission.
Abstract:
A fuel injection controlling device for a two-cycle engine includes an electronic fuel injection system having a fuel injection quantity determining device for determining a fuel injection amount in response to rotational speed and throttle opening of the engine. At engine start, the controlling device, in response to operation of an engine kick starter, sequentially decreases starting fuel amount as the number of actuations of the kick starter increases. Fuel injection amount is also decreased in response to increasing engine temperature.
Abstract:
A rally-oriented meter device for motorcycles, includes a meter unit, a fixing assembly for fixing the meter unit in the vicinity of a handle bar of the motorcycle, and a sensor for detecting the number of revolutions of a front wheel of the motorcycle. The meter unit has an internal electric circuit, a display section, and an operational section. The internal electric circuit comprises an integration circuitry for an integration of a travel distance of the motor cycle. A correction circuitry provides the integration circuitry with a correction signal representing a correlation factor. The operational section comprises a calibration switch system for providing a control signal for commanding the correction circuitry to start and stop an action thereof to determine the correction factor. The display section comprises a first display element for displaying the travel distance in a predetermined unit, and a second display element for displaying the travel distance in a unit smaller than the predetermined unit. The fixing assembly is to detachably attach the meter unit in the vicinity of the handle bar. The sensor is secured to a front fork of the motor cycle and disconnectably connected through a connector to the internal electric circuit. The display section and the operational section are both provided in an upper face of the meter unit. The calibration switch system comprises a calibration switch. The calibration switch has a lower height than a top face of the display section.
Abstract:
An ignition timing control system for a two-cycle internal combustion engine compares a first reference signal which rises to a predetermined level as a first pulse signal is generated corresponding to a predetermined crank angle and which thereafter decays at a predetermined slope, and a second reference signal of generally trapezoidal shape and having a pulse width corresponding to the pulse width of a second pulse signal corresponding to a predetermined crank angle. When the signal level of the second reference signal rises above that of the first reference signal, an ignition signal is generated. A first reference signal control circuit generates a triangular signal in synchronism with the second pulse signal, which triangular signal rises at a predetermined slope, and controls the first reference signal in such a manner that the first reference signal decays at a slope gentler than the predetermined slope from an instant in time at which the signal level of the triangular signal exceeds a predetermined level.

Abstract:
A fail detecting device for a rotation angle sensor, for detecting a fail of the rotation angle sensor even if the number of rotation angle sensors is one. A cam is configured to be driven to rotate in one direction by an electric motor to reciprocate a push rod. An output voltage of an angle sensor is set so that the region equal to or lower than a first predetermined voltage and the region equal to or higher than a second predetermined voltage higher than the first predetermined voltage are recognized as a dead zone. The elapsed time after the transition to the dead zone is measured by a timer and it is determined that the angle sensor is in the fail state if the output voltage corresponding to the dead zone is detected although the estimated time of the passage through the dead zone has elapsed.
Abstract:
A heating value calculation part obtains a substantial heating value based on the difference between a heating value and a radiating value attributed to a motor supply current. The radiating value is obtained by a difference between a motor estimation temperature Td and an ambient temperature Tm. The heating value is cumulated in the heating value calculation part and the cumulated value is inputted to a cumulated buffer. A cumulated value TS which is obtained by adding an initial temperature T0 to the cumulated value Td is inputted to a target current value ratio map and a target current value upper limit map. One of the target current values is selected and the selected target current value is inputted to a current feedback control part. The current feedback control part controls a motor output part such that the motor supply current is converged to the target current value.
