no. 1 approach

[0029] Hereinafter, a first embodiment of the present invention will be described. 1 shows a steering mechanism 2 mounted with a vehicle sensor device 1 according to this embodiment, and also shows an ECU 3 in an ESC system into which a detection signal from the vehicle sensor device 1 is input. Fig. 2 is a schematic diagram of a section along line A-A in Fig. 1 . Hereinafter, the arrangement structure of the vehicle sensor device 1 will be described with reference to these drawings.

[0030] The vehicle sensor device 1 according to this embodiment includes a vehicle motion amount sensor 1a and a steering angle sensor 1b. The vehicle motion amount sensor 1a includes driving dynamics sensors such as a front-rear acceleration sensor for detecting acceleration Gx in the vehicle front-rear direction, a lateral acceleration sensor for detecting acceleration Gy in the vehicle lateral direction, and a rotation angle sensor for detecting a rotation angle around the center of gravity ...

no. 2 approach

[0069] Hereinafter, a second embodiment of the present invention will be described. In the first embodiment described above, the vehicle sensor device 1 is mounted to the combination switch device 2c. In the present embodiment, the vehicle sensor device 1 is mounted to a position different from that of the first embodiment.

[0070] FIG. 8 is a schematic diagram showing a power steering device in which the vehicle sensor device 1 is mounted in the present embodiment. FIG. 9 is a sectional view of a part of the rack in the power steering device shown in FIG. 8 , to which the vehicle sensor device 1 is attached.

[0071] The power steering device 11 shown in FIG. 8 is of a rack assist type, and includes a rack assist mechanism 12 that assists the forward and backward movement of the rack by means of rotation of a motor.

[0072] The rack assist mechanism 12 includes a ball screw 13 , an assist motor 14 and a rack shaft 15 . When the pinion shaft 16 connected to the steering s...

Embodiment approach

[0079] In the above embodiments, the vehicle sensor device 1 is located inside or near the tilt mechanism 2a, so that the influence of the tilt angle θ on the vehicle motion sensor 1a can be eliminated. However, the vehicle motion amount sensor 1a may be provided in such a manner that the vehicle motion amount sensor 1a is not affected by the inclination angle.

[0080] For example, the vehicle motion amount sensor 1a may be positioned on a portion where the tilt angle θ of the tilt mechanism 2a does not change due to tilt adjustment, instead of a portion where the tilt angle θ of the tilt mechanism 2a changes due to tilt adjustment (steering side ). In this case, the vehicle motion sensor 1a still needs to be located in the vehicle compartment to reduce the influence of heat and vibration in the engine room on the vehicle motion sensor 1a, thereby simplifying the structure of the electrical wiring and facilitating the installation of the electrical wiring.

[0081] As shown ...

Abstract

A sensor device for a vehicle enabling the simplification of a wiring structure and an improvement in mountability and a vehicle stabilization system using the sensor device. The sensor device is so formed that a vehicle momentum sensor (1a) and a steering angle sensor (1b) are stored in a same case or mechanically direct-connected to the case. Thus, since electric wires for inputting detection signals from the vehicle momentum sensor (1a) and the steering angle sensor (1b) into an ECU (3) can be unified and all sensors can be mounted in the same case, the wiring structure can be simplified and the mountability can be improved.

Description

technical field [0001] The present invention relates to a vehicle sensor device including a combination of a vehicle motion amount sensor and a steering angle sensor for detecting a wheel steering angle, and a vehicle stabilization system using the vehicle sensor device. The vehicle motion amount sensors include driving dynamics sensors for detecting physical quantities, such as yaw rate sensors and lateral acceleration sensors. Background technique [0002] Conventionally, an ESC (Electronic Stability Control) system is known (for example, see Japanese translation document 2004-506572 of published PCT international application), which is based on detection from a vehicle motion amount sensor and a steering angle sensor The signal performs control of stabilizing the vehicle, wherein the vehicle motion amount sensors include driving dynamic sensors for detecting physical quantities, such as a yaw rate sensor and a lateral acceleration sensor. In this ESC system, the vehicle ...
