摘要： PURPOSE:To provide a wide angle laser device with optimum characteristics according to operation conditions, circumferential conditions, etc., and safety. CONSTITUTION:A time difference between the time when a reflection beam of pulse laser beam sent out from a light sending part 110 against a reflector is received at a light reception part 3 composed of a plurality of right reception elements 302 and the time until the reflection beam is received after it is sent out, and a distance from the position of the element 302 to the position of the reflector are measured by means of a distance/direction detection part 7. In this case, combination of reception elements 302 is controlled by reception element combination control means 9, 10 according to outputs of detection means 21 detecting conditions of a vehicle and conditions outside it, and outputs of the elements are added with adding means 11, then according to the addition output the distance and direction to the reflector is measured.

摘要： PURPOSE:To detect the speed of a moving object in a short time without requiring memory or correlation operations by taking out of an array of sensitivity- variable photo detectors a signal indicating the sum of products of light and sensitivity, thus detecting the speed. CONSTITUTION:An array of sensitivity-variable photo detectors (retinal chip circuits) 20, comprising light receiving elements arranged in a line whose sensitivity can be varied according to voltage, is disposed parallel to a road surface 4 so that the direction of speed detection coincides with that of the line of elements. A control signal Cj is input from a control signal generator circuit 30 in the direction of the line of retinal chip circuits 20, and a current (y) that is proportional to the sum of products of the quantity P of light impinging on a picture element Gj and the control signal Cj is output to a signal converter circuit 31. To measure speed, the counter (n) of a speed measuring circuit 32 is set to zero, and when actuation of the circuit 30 is ordered the circuit 30 outputs conversion timing signals to the circuit 31 after the first and final periods of each cycle. The circuit 31 converts the current (y) stored in the previous cycle to voltage Y and outputs the voltage, and then the circuit 32 increments the counter by 1 and calculates the speed from the output Y.

摘要： PURPOSE:To eliminate the troublesomeness by judging whether the driver of a vehicle recognizes the dangerous state or not by a danger recogition judging part to inform a danger avoiding part of the judging result and omitting the danger avoiding or lessening operation at the time when a driver's own vehicle is in the dangerous state but he recognizes this state. CONSTITUTION:A danger recognition judging part 50 detects the state of the driver by the outputs of a vehicle outside state monitor part 20 and a driver monitor part 40. That is, it is detected whether the driver looks aside or not basing on the signal indicating the movement of the sight from the driver monitor part 40 and the signal indicating the position of a signal from the vehicle outside state monitor part 20, and it is detected whether his blood pressure, heart rate, and bodily temperature are changed or not by signals of them from the driver monitor part 40. When judging it basing on these detection results that the driver looks aside and his heart rate and bodily temperature are not changed, the danger recognition judging part 50 judges that the driver does not recognize the dangerous state. In this case, a danger avoiding part 60 is instructed to perform the danger avoiding operation.

摘要： PURPOSE:To improve accuracy in determining deterioration of a catalyst by taking respective air-to-fuel ratios on an upstream and downstream the catalyst, obtaining a value indicating a correlation per frequency component and determining deterioration of the catalyst. CONSTITUTION:A tertiary catalyst 2 is provided on an exhaust gas path 1, while exhausted gas G whose air-to-fuel ratio is periodically varied is made flow from an upstream of the catalyst 2. Under the conditions, respective air-to- fuel ratios V1, V2 are detected for predetermined sampling time from upper and lower linear air-to-fuel ratio sensors 3, 4 provided on an upstream and downstream the catalyst 2. The output V1, V2 waveforms are converted into a value indicating correlation per frequency component (coherence) in a mutual correlation value calculating process. Here the output V1, V2 waveforms are taken into an FFT module 5, where a pair of random input functions are Fourier-transformed and a coherence function is calculated. The obtained coherence function is subjected to determination of deterioration in a deterioration determining process, and according to an obtained deterioration signal a warning means such as a buzzer and an alarm lamp is driven so that deterioration of the catalyst is informed.

摘要： PURPOSE:To enable achievement of start function, first move function, and charging function only with a motor so as to reduce cost by making an engine rotate via a differential gear mechanism by a motor when the engine is started and making the motor function as a generator after start of engine ends. CONSTITUTION:During ordinary running of vehicle, a motor 5 functions as load. Rotating output of an engine 2 is transmitted to a transmission 3 via a differential gear mechanism 10 and a gear 20 as reaction force torque due to load torque of the motor 5, and further transmitted to wheel via a decelerator 4. Torque transmission amount for a transmission 30 is controlled arbitrarily by controlling torque of the motor 5 on the charge side, and a charger 7 is charged via a power converter 6 due to rotating output of the motor 5 which functions as load. When the engine 2 starts, power is supplied to the motor 5 from a condenser 7 by controlling the power converter 6, and rotating drive force of this motor 5 is transmitted to a differential gear mechanism 10 from the third rotary shaft 1c via gears 25, 24 to perform cranking.

摘要： PURPOSE:To improve purifying efficiency by comparing an air-fuel ratio sensor output with a basic signal through a waveform processing means whose time limit is controlled, generating an oscillation signal centered on integration value of an air-fuel ratio discriminating signal to add it to the air-fuel ratio discriminating signal for feedback control. CONSTITUTION:Basic injecting time is determined from an intake air amount Qa and engine speed Ne by a CPU 7 used in ECU 70 so as to add compensation of water temperature Tw, intake air temperature TA and acceleration increase. Besides, the output of an air-fuel ratio sensor 12 is compared with a reference signal 21 by a comparator 20 through a waveform processing circuit 26 whose time limit is controlled so as to integrate a rich/lean discrimination signal by means of an integrator 22, and the oscillation signals of amplitude and frequency corresponding to an engine running condition are generated by means of a generating circuit 24 with the output level centered. The discriminating signal is added to a signal proportionally amplified in a circuit 23 according to a driving condition for adding feedback compensation of air-fuel ratio. It is thus possible to make sufficient use of exhaust gas purifying ability of a catalytic converter.
