摘要： The leading-vehicle detection apparatus, mounted on a sensing vehicle, radiates a laser beam from a transmitter of a laser radar. The laser beam is reflected by objects including any vehicle in front of the sensing vehicle, and is received by a receiver in the laser radar. The distances between the vehicle and the objects are calculated based on a comparison of the radiated laser beam and the reflected, received laser beam. The calculated distances are stored corresponding to the sweeping positions of the laser beam. Relative speeds between the vehicle and the objects are calculated from the variations over time in the distances. Based on the relative speeds, only the distance information for objects moving at almost the same speed as the sensing vehicle is selected. On the other hand, comparison patterns of inherent vehicular characteristics are stored beforehand. The selected distance information is compared with the comparison patterns. Information matching the comparison patterns is selected. Through this pattern-matching process, distance information for only the leading vehicle is quickly selected. Distance information for a guardrail, a center line, or other objects that are mistaken for moving objects is eliminated.

摘要： Method and apparatus for controlling an electromagnetic powder clutch connected to a vehicle engine and including a coil for engaging the powder clutch to transmit an output torque of the engine as a function of an electric current to be applied to the coil such that a variation in the engine torque is absorbed by a slip of the powder clutch. An optimum amount of slip of the powder clutch is determined based on a currently required engine output and a detected output speed of the clutch. A basic control value for controlling a magnitude of the electric current to be applied to the coil is determined based on the detected engine torque, such that the determined magnitude of the electric current permits engagement of the clutch so as to transmit the detected engine output torque. The basic control value is compensated for the determined optimum amount of slip of the clutch, thereby adjusting the transmission torque of the clutch so as to absorb the variation in the output torque of the engine.

摘要： A method and an apparatus of controlling an electromagnetic clutch incorporated in a power transmission system of a vehicle to transmit an output of an engine to the drive wheels of the vehicle is disclosed. An amount of electric current applied to the clutch is regulated to control an engaging action of said electromagnetic clutch, based on either a variation in rotating speed or torque of an output shaft of the electromagnetic clutch, or based on the frequency or number of variations per unit time in rotating speed or torque of the output shaft, as compared with the frequency or number of ignitions or combustions per unit time of the engine. In this way a variation in output torque of the engine is absorbed by the electromagnetic clutch for improved drivability, while a transmission power loss in the clutch is kept to a minimum for maximum fuel economy.

摘要： The ignition timing of an engine is changed by a predetermined value to cause fluctuations in torque to an output shaft of the engine. Vibrations caused by the fluctuations in torque to an engine block are detected and the ignition timing is controlled so that the vibrations can be reduced to the minimum. Thus, the ignition timing of the engine can be controlled to the optimum condition so that the engine can be operated at the highest condition at all times.
