摘要： PROBLEM TO BE SOLVED: To provide a detection method detecting abnormalities in a wiring of a sensor circuit network 1, without increasing a column wiring 2a and row wiring 2b.
SOLUTION: For example, when the abnormality of the column #1 and the column #2 of the sensor circuit network 1 is detected, a beginning end of the column #1 is connected to low electrical potential side of a pull-up resistor Rp. The beginning end of the column #2 is connected to the ground. A closed circuit is formed by connecting the pull-up resistor Rp and a resistor Rd in series. Then, a specified voltage is applied to the closed circuit, the voltage between terminals of the pull-up resistor Rp is output to ECU. If the closed circuit is opened, the voltage between terminals becomes 0 V, if the closed circuit is short-circuited, the voltage between terminals becomes equipotential to the applied voltage to the closed circuit. If there is no abnormality in the two column wirings 2a (#1, #2) forming the closed circuit, a partial voltage {R×Vcc/(R+Rp)}, corresponding to the resistance ratio between the pull-up resistor Rp and the resistor Rd, is detected.

摘要： PROBLEM TO BE SOLVED: To provide a collision detection device for vehicle of optical fiber type capable of reducing the dispersion of the detection sensitivity owing to the shape of a colliding body. SOLUTION: A fiber part 21 of an optical fiber sensor is installed being pinched between a bumper reinforcement 7 and a front bumper 1, and a load transmitting plate 20 is installed pinched between the fiber part 21 and the front bumper 1. A fore-and-aft extension part 9 having a rod shape is protruded backward from the load transmitting plate 20 and is fitted loosely in a hole 10 formed in the bumper reinforcement 7. When a collision load is applied to the load transmitting plate 20, therefore, the plate 20 retreats wholly and transmits the collision load to the fiber part 21 of the optical fiber sensor, so that part of the plate 20 deflects backward so that the fiber part 21 is prevented from deforming locally.

摘要： PROBLEM TO BE SOLVED: To provide a capacitive occupant sensor and a capacitive occupant sensor device, capable of discriminating an adult of small build from an adult of large build. SOLUTION: A cushion 20 and a floating electrode 30 are provided on one of surfaces 11 of an electrostatic sensor mat 10. Thus, the cushion 20 sandwiched between the floating electrode 30 and the electrostatic sensor mat 10 crushes by a weight of an occupant 46. Since a distance between the floating electrode 30 and the electrostatic sensor mat 10 (a main electrode 17a and a sub electrode 17b) varies depending on the build of the occupant 46, a difference in capacitance between an adult 42 of large build and an adult 43 of small build is clear. Therefore, distinction between the adult 42 of large build and the adult 43 of small build can be made. COPYRIGHT: (C)2011,JPO&INPIT
