The invention provides a vehicle steering column installation angle measuring method and measuring device, which relate to the measurement of a steering column installation angle of a vehicle. The measuring method comprises: detecting an installation angle of a steering wheel connected to a steering column; acquiring an angle between the steering column and the steering wheel; and obtaining the steering column installation angle based on the steering wheel installation angle and the angle between the steering column and the steering wheel. The measuring device comprises: an angle measuring device for measuring the installation angle of the steering wheel; an angle measuring device installation base for keeping the angle measuring device parallel to a first plane, where an annular portion of the steering wheel is located, in the length direction of the vehicle; and a steering wheel butting portion for keeping the angle measuring device parallel to the first plane. The angle measurementis guaranteed to be accurate while making an operation very easy, and in addition, the simple structure also enables the measuring device to be very easy to machine and manufacture.
Description
Technical field [0001] The invention relates to the measurement of the installation angle of the steering column of a vehicle, in particular to a method and a measuring device for the installation angle of the steering column of a vehicle. Background technique [0002] Before the collision test of the vehicle, the corresponding devices or units in the vehicle need to be inspected to facilitate the comparison with the corresponding data after the vehicle collision. Therefore, it is particularly important to perform necessary inspections on the corresponding devices or units in the vehicle. The installation angle of the steering column is very important for the setting of the vehicle's internal parameters and can provide accurate angle measurement data for the development of the driver's front airbag calibration. [0003] However, the steering column installation angle cannot be accurately measured due to the position of the steering column, which results in inaccurate detection of ...
