    摘要： A method of accurately determining the location of each cylinder top dead centre position of an engine relative to a reference pulse whose location is not precisely known, by the steps of:
        generating a reference signal at a reference angular position of the output shaft of the engine before top dead centre of one of the cylinders;
        generating periodic speed pulses corresponding to successive equally spaced positions of the output shaft of the engine as the output shaft rotates;
        determining the angle of rotation d₁ of the output shaft between the reference signal and the subsequent speed pulse;
        measuring the rotational velocity of the output shaft substantially at the time of occurrence of the subsequent speed pulse;
        measuring the angle of rotation d₄ of the output shaft from the subsequent speed pulse to the angular position of the output shaft at which the rotational velocity of the output shaft first becomes equal to the measured rotational velocity; and
        indicating a cylinder top dead centre position at an output shaft angular position offset from the reference angular position by an angle equal to d₁ + (d₄/k) where k is a predetermined consta nt.

    摘要： An adaptive cruise control system that provides a smooth following by limiting the headway to keep it lower than a predetermined maximum. The present invention accomplishes this objective through systematically limiting the headway. In particular, the present invention reduces a time related speed multiplier used in calculating the desired headway, to maintain a headway that is less than an effective maximum sensor range for the adaptive cruise control system.

    摘要： An adaptive cruise control system for a vehicle 10 maintains a desired selected driver-set speed V D in the absence of a detected preceding obstructing vehicle 12 and adjusts the source vehicle speed V S when an obstructing vehicle 12 is detected to maintain a following distance D D that is set by the vehicle operator. An alert distance D alert is computed which is a predetermined function of a distance based on driver reaction time T r . To provide for the driver selectable trailing distance D D , the driver reaction term T r of the alert distance D alert is adjusted by the vehicle operator to achieve a desired distance D D to the obstructing vehicle.
