摘要： The invention aims to increase an expansion angle in a road surface direction in a short-distance area without setting a detection range one-sidedly and without sacrificing a maximum detection distance.A double-focus lens is integrally formed by disposing a short-focus portion in the vicinity of a center and a long-focus portion on the periphery of the short-focus portion. A light source is disposed at a distance slightly shorter than the focal length of the short-focus portion of the double-focus lens. When light is emitted from the light source to the double-focus lens, light emerging from the short-focus portion has a small expansion angle such as not to diffuse largely. Therefore, the emerging light can be caused to reach a long distance. On the other hand, light emerging from the long-focus portion has a large expansion angle such as to diffuse to some extent. Therefore, the emerging light can be caused to travel over a short-distance area and, more particularly, over an area extended in a widthwise direction of a road surface.

摘要： A laser array circuit decreases the size of a circuit pattern. A laser-diode (LD) driving switching element with a low on resistance is used in common with and switches conduction and non-conduction of a large current to each of a plurality of charge capacitors and charge switching elements that accumulate charge in the charge capacitors in respective drive circuits.

摘要： A radar system of a vehicle has a zero-cross comparator, an integrator, and a sensor. The comparator compares a light reception signal output from each one of photoreceptive elements with a predetermined standard signal and outputs a comparison signal indicating two different states corresponding to a result of the comparison. The integrator samples the comparison signal and converts the comparison signal into one-bit digital data. The integrator integrates the digital data for each photoreceptive element. The sensor compares the integrated data of each photoreceptive element with a predetermined integration standard value. The sensor senses a reflection object based on the integrated data equal to or greater than the integration standard value.

摘要： In an object recognition apparatus for a vehicle which uses intensities of reflected waves from reflecting objects to make a recognition on whether a reflecting object is a vehicle or a non-vehicle, a plurality of transmission waves are emitted to receive a plurality of reflected waves from the reflecting objects, and a decision is made as to whether or not the reflecting object producing the plurality of reflected waves is a unitary reflecting object. If the decision shows a unitary reflecting object, the highest intensity of intensities of the reflected waves from the unitary reflecting object is compared with a reference intensity to makes a decision on whether the reflecting object is a vehicle or a non-vehicle. This enables univocally making a decision for each unitary reflecting object as to whether the reflecting object is more likely to be a vehicle or to be a non-vehicle, thus improving the recognition accuracy.

摘要： A laser radar sensor includes a photoreceptor, a dummy circuit, an amplifier, a selector, and the first and the second detection circuits. A photoreception signal outputted from the photoreceptor and an output signal of the dummy circuit are amplified by the amplifier, and inputted to the second detection circuit. A noise component included in the photoreception signal based on the output signal of the dummy circuit when distance detection is not performed. The distance detection is performed based on the reception signal from which the noise component is removed. As a result, a reduction in detectable distance of the laser radar sensor is less likely to occur. Furthermore, the noise component is detected using the dummy circuit and the selector. Thus, the consideration of the predetermined rotation angle is not required in optical system design and limiting factors in the optical system design can be reduced.

摘要： An integrator of a vehicular radar system has multiple switches and multiple capacitors, which are connected with the switches, for each one of photoreceptive elements. The integrator integrates light reception signals, which are output from the photoreceptive elements, by switching the switches to a connected state one after another in a predetermined order at a predetermined time interval until a predetermined time passes after every emission of the laser light and by switching the switches to the connected state one after another in a predetermined order at a predetermined time interval if the laser light is emitted predetermined times. Thus, the integrator can integrate the light reception signals, which are output from the multiple photoreceptive elements, in parallel.

摘要： A distance measurement apparatus includes a transmitting device for transmitting a forward electromagnetic wave. A receiving device operates for receiving an echo wave caused by reflection of the forward electromagnetic wave at an object, and converting the received echo wave into a first received signal. A scattered-wave detecting device operates for detecting a scattered wave reaching the receiving device and caused by reflection of the forward electromagnetic wave at an obstacle which occurs prior to the reflection of the forward electromagnetic wave at the object. A cancel-signal generating device operates for generating a cancel signal to cancel a scattered-wave-corresponding component of the first received signal generated by the receiving device in response to the scattered wave detected by the scattered-wave detecting device. A scattered-wave canceling device operates for removing the scattered-wave-corresponding component from the first received signal in response to the cancel signal generated by the cancel-signal generating device to change the first received signal to a second received signal. A distance calculating device responsive to the second received signal operates for measuring a time interval between a moment of the transmission of the forward electromagnetic wave by the transmitting device and a moment of the reception of the echo wave by the receiving device, and calculating a distance to the object on the basis of the measured time interval.
