no. 1 approach

[0032] Hereinafter, a first embodiment of the present invention will be described. figure 1The steering mechanism 2 mounted with the vehicle sensor device 1 according to this embodiment is shown, and the ECU 3 in the ESC system into which the detection signal from the vehicle sensor device 1 is input is also shown. figure 2 is along figure 1 Schematic representation of the cross-section of midline A-A. Hereinafter, the arrangement structure of the vehicle sensor device 1 will be described with reference to these drawings.

[0033] 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 rot...

[0072] 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.

Figure 9 yes Figure 8 A cross-sectional view of a part of a rack in a power steering apparatus shown in , where the vehicle sensor device 1 is attached to the rack.

[0074] Figure 8 The illustrated power steering device 11 is of a rack assist type, and includes a rack assist mechanism 12 that assists forward and backward movement of the rack by means of rotation of a motor.

[0075] The rack assist mechanism 12 includes a ball screw 13 , an assist motor 14 and a rack shaft 15 . When the pinion sh...

Embodiment approach

[0082] 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.

[0083] 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.

Abstract

A vehicle sensor device capable of simplifying the wiring structure and facilitating installation, and a vehicle stabilization system using the vehicle sensor device. The vehicle sensor device is configured such that the vehicle movement amount sensor (1a) and the steering angle sensor (1b) are installed in the same housing or are directly mechanically connected with the housing. Therefore, it is possible to put together the wiring harness for transmitting detection signals from the vehicle motion amount sensor (1a) and the steering angle sensor (1b) to the ECU (3). In addition, since all sensors can be located in the same housing, the structure of the harness can be simplified and can be installed more easily.

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 ...
