摘要： PROBLEM TO BE SOLVED: To high-precisely discriminate an obstacle in the vicinity of a crossing rod. SOLUTION: A radar processing means outputs a starting signal for a light transmitting and receiving means when an obstacle 18b is detected in the vicinity of the crossing rod 17, and the light transmitting and receiving means started by a starting signal transmits light beams and receives the transmitted light beams in parallel to the crossing rod 17 in the vicinity of the crossing rod 17 on the side closer to roadways 12 and 14 than the crossing road 17. A beams detecting means to which light beams received by the light transmitting and receiving means are inputted outputs a signal to detect an obstacle in vicinity of a railroad crossing when it is detected that the obstacle 18b is present in a railroad crossing 16 in the vicinity of the crossing rod 17. An alarm processing means inputs a railroad crossing obstacle detecting signal and a signal to detect an obstacle in the vicinity of the crossing when a train detecting signal is inputted and outputs an alarm signal when the obstacle is recognized.

摘要： PURPOSE:To determine the distance with high accuracy by calibrating the time/ voltage conversion characteristics using the results of time/voltage conversion effected with precise time width thereby ensuring a positive calibration regardless of fluctuation in circuit elements, temperature variation, drift, etc. CONSTITUTION:A drive section 1 delivers a transmission start signal to a time/ voltage converting section 7 and a precise time width generating section 9. The generating section 9 delivers a stop signal to an OR circuit 11 with a predetermined accurate time lag behind reception of the start signal. The OR circuit 11 selects an output signal from the generating section 9 or a comparing section 6, being inputted earlier, and delivers the selected signal. A converting section 7 converts the time, elapsed after input of the start signal before input of the stop signal, into a voltage and the voltage level is detected at the time of input of the stop signal. A calibrating section 801 calibrates the time/voltage characteristics and delivers the calibration results to a distance calculating section 802.

摘要： PURPOSE:To obtain a radar apparatus, for a vehicle, in which a reflecting body, especially a reflector which is installed at the rear part of a car and a two-wheeled vehicle or a reflector which is installed on a guardrail, can be discriminated from others. CONSTITUTION:Electromagnetic waves are transmitted by a transmission means 4, and electromagnetic waves reflected by a reflecting body 5 are received by a reception means 24. A distance up to the reflecting body 5 is detected by a distance detection means 26 on the basis of the time which elapses until the electromagnetic waves are received by the reception means 24 since they have been transmitted by the transmission means 4. The product of the fourth power of the distance up to the reflecting body 5 detected by a reflecting body discrimination means 27 multiplied by the intensity of reflection is computed, and the reflecting body 5 is discriminated according to the value of the product.

摘要： PURPOSE:To enable a distance-measuring accuracy to be improved by automatically setting a reference value for comparison based on a signal level when there is no signal. CONSTITUTION:A distance is measured based on a propagation delay time between a light-transmission timing of a light transmitter 2 and an output timing of a comparator which is equivalent to a light-reception timing of a light receiver 3. Transmission of light is temporarily paused by a light-transmission controller 9 and a reference value of the comparator 7 is set variably by a threshold voltage generator 10 based on a signal level which is detected by an A/D converter 6 during thus time, thus improving the distance-measuring accuracy by a single structure.
