Abstract
A collision detection sensor for a vehicle is provided with sensor cells totaling i, which are linearly arrayed with a predetermined pitch in a bumper of the vehicle and arranged in a longitudinal direction of the bumper. The sensor cells respectively detect pressures which are applied to the bumper at different positions thereof due to a collision between an obstacle and the bumper. Wirings of the sensor cells totaling i have a connection relation which is same with that of a n×m matrix wiring arrangement (i≦n×m). Thus, the wiring space can be decreased by a wiring number reduction, so that the vehicle-mounting performance can be improved.
Claims11
A collision detection sensor for a vehicle, the collision detection sensor comprising
- sensor cells totaling i (i is an integer larger than or equal to “1”), which are linearly arrayed with a predetermined pitch in a bumper of the vehicle and arranged in a longitudinal direction of the bumper, wherein:
- the sensor cells respectively detect pressures which are applied to the bumper at different positions thereof due to a collision between an obstacle and the bumper;
- and
- wirings of the sensor cells have a connection relation which is same with that of a n×m matrix wiring arrangement (n, m is an integer larger than or equal to “2”, and i≦n×m).
