Mounting structure of turning-angle sensor of automobile electronic stability system

Abstract

The invention relates to a mounting structure of a turning-angle sensor of an automobile electronic stability system. The mounting structure comprises an electric steering column casing, an input shaft, an output shaft, a torsion rod and a turning-angle sensor, wherein the input shaft and the output shaft are arranged in the electric steering column casing; the torsion rod is arranged between the input shaft and the output shaft; the turning-angle sensor is arranged in the electric steering column casing. According to the mounting structure disclosed by the invention, the turning-angle sensor is arranged at the inner part of the electric steering column casing in an integrated manner, so that the integrated detection of a turning angle and a turning moment is realized, and turning-angle signals and turning-moment signals are transmitted through a bus. Compared with a conventional technical scheme, the mounting structure disclosed by the invention has the advantages that the mounting space of a whole automobile is saved, and the integrated design and assembly of parts is realized; besides, the cost of the whole automobile is reduced. Through the adoption of the mounting structure, electromagnetic radiation can be well resisted, electrical protection can be well provided, and the possible damage of the turning-angle sensor, caused by demounting and mounting, is reduced.

Description

technical field [0001] The invention belongs to the technical field of automobile steering systems, in particular to a mounting structure for a rotation angle sensor of an automobile electronic stability system. Background technique [0002] With the development of automobile technology, current automobiles have been generally equipped with ESP (automotive electronic stability system) and EPS (electronic power steering system). ESP is mainly composed of central control unit (ECU), actuator, steering wheel angle sensor, vehicle speed sensor, braking force sensor, yaw rate sensor, etc. During the driving process of the car, the steering wheel angle sensor perceives the turning direction and angle that the driver is trying to operate , the yaw rate sensor detects the deflection of the car along the vertical axis (the size of the deflection represents the stability of the car, if the yaw rate reaches a threshold, it means that the car is in dangerous conditions such as sideslip ...
