Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mounting structure for various sensors provided in a vehicle.
[0002]
[Prior art]
A vehicle such as a four-wheeled vehicle is subjected to a force that tilts in the vehicle width direction (hereinafter referred to as rolling) when turning a corner during traveling, and the front and rear of the vehicle during acceleration or braking by braking operation. A force that tilts in the direction (hereinafter referred to as pitching) is received.
On the other hand, in recent years, various sensors have been attached to the vehicle in order to accurately grasp the correct behavior of the vehicle. As types of sensors, there are gravity sensors such as an airbag sensor for operating an airbag and an ABS (Antilock brake system) sensor for controlling a brake operation. In addition, a vehicle having a side skid control device for a vehicle has a yaw rate sensor that detects displacement in the rotational direction. When performing the above-described ABS control and trunk control, the yaw rate sensor is more accurate and textured. There is an advantage that fine control becomes possible.
[0003]
Gravity sensors such as airbag sensors and ABS sensors are placed at the center of the vehicle as much as possible, that is, to know exactly what acceleration the vehicle is receiving when the vehicle is rolling or pitching. It is desirable.
Therefore, these sensors may be arranged inside the center console extending in the front-rear direction between the driver's seat and the passenger seat in the passenger compartment.
[0004]
[Problems to be solved by the invention]
However, an airbag sensor and an ABS sensor have to be arranged in a limited space such as a center console, and it has been difficult to lay out especially in a light vehicle. Furthermore, although the yaw rate sensor is not as large as the gravity sensor, it is preferably arranged at the center of the vehicle so as not to be affected by rolling and pitching.
The present invention has been made in view of the above problems, and an object thereof is to provide a sensor mounting structure in which various sensors such as an airbag sensor and an ABS sensor can be disposed in a limited narrow space.
