Problems solved by technology

[0006] However, there are certain difficulties in the installation of magnetic induction sensors with more reliable work. The installation space under the steering wheel is limited, and components such as clock spring mechanisms and combination switches need to be installed, especially when installing magnetic induction sensors. Axial positioning mechanisms, such as the simple cooperation between the boss and the groove, the opening stop ring, etc., often interfere with the installation so that the magnetic induction sensor cannot be installed, and the positioning pin is used for positioning, because the pin hole and the positioning pin cannot ensure alignment, so there is no guarantee that the installation process will go smoothly

Abstract

The invention provides a steering wheel corner sensor device comprising a magnetic induction sensor (2) and a corner driving part (5), wherein a driving structure is formed between an upper pipe section of the corner driving part and a clock spring mechanism (1); the inner periphery of the upper pipe section is provided with a radial locating mechanism and a first axial locating mechanism, and the inner periphery of the upper pipe section is provided with a second axial locating mechanism; an inner bushing of the magnetic induction sensor is provided with a third axial locating mechanism; and the outer periphery of the upper pipe section and the inner bushing of the magnetic induction sensor are also provided with a circumferential locking and driving mechanism. The steering wheel corner sensor device adopts the magnetic induction sensor which is more reliable in work, realizes the installation and the precise location of the magnetic induction sensor within a limited space below a steering wheel and reliably transfers the rotation of the steering wheel to the magnetic induction sensor. In addition, the invention also provides an automobile electronic stabilization system.

Description

technical field [0001] The present invention relates to a steering wheel angle sensor device for an electronic stability system (ESP) of an automobile, and more particularly, to a steering wheel angle sensor device including a rotation angle sensor. In addition, the present invention also relates to an automotive electronic stability system comprising the steering wheel angle sensor device. Background technique [0002] With the development of the automobile industry, people have paid more and more attention to the stability and safety of automobile braking and steering operations. At present, automobiles have been generally equipped with an ABS system (anti-lock braking system). During the braking process of a car, the ABS system generally takes effect when a certain wheel has a tendency to lock in advance, and it is mainly a passive safety system. However, in today's ever-changing road conditions and increasingly congested traffic, this passive ABS system is far from mee...
