摘要： An antiskid device comprising a skid detector composed of a peripheral wheel deceleration detecting circuit and a peripheral wheel subdeceleration detecting circuit for differentiating the output signal from said peripheral wheel deceleration detecting circuit to detect a first derivative of the peripheral wheel deceleration (referred to as the subdeceleration hereunder) which can be regarded to be inversely proportional to the adhesion coefficient of the road surface, and a braking force controlling mechanism to control the braking force to be applied to the wheel, whereby said braking force controlling mechanism is actuated when the peripheral wheel deceleration from said peripheral deceleration detecting circuits exceeds a reference value corresponding to the adhesion coefficient of road, while said reference value is varied in inverse proportion to the output from said peripheral wheel subdeceleration detecting circuit to continuously vary the operation starting point of said braking force controlling mechanism in accordance with the adhesion coefficient of road such that said braking force controlling mechanism is operated to continuously produce the braking force well suited to the adhesion coefficients of roads ranging from a dry asphalt road surface and the like where the adhesion coefficient is large to a snowy frozen road surface and the like where the adhesion coefficient is small, thereby effecting the antiskidding operation safely and efficiently.

摘要： The Doppler effect is used to detect the imminence of a potential collision between a moving vehicle and an object in its path to provide a detecting signal for the safety of the vehicle occupants. A potential collision detecting system includes an ultrashort wave generator, a coupler connecting the generator to a transmitting and receiving antenna, a mixer-detector connected to the generator and the antenna through the coupler, an amplifier, a filter, an AC-DC converter, a comparator and a safety device for protecting vehicle occupants. The mixer-detector derives the Doppler signal and the time remaining until the occurrence of a collision is derived by converting the frequency of the Doppler signal to a signal level by means of a filter having certain frequency characteristics. The comparator converts the remaining time to a voltage and, when the voltage exceeds a predetermined value, the comparator issues a collision detecting signal to activate the safety device. The filter is a band pass filter which cuts off frequencies in the low frequency range, where operation of the safety device is not required, and in the high frequency range corresponding to a high relative velocity of the vehicle not likely to be met in practice.
