Problems solved by technology
[0002] When the steering wheel of the vehicle is driving or parking, the steering wheel angle is often misaligned. When the steering wheel is in the three positions of 0 degrees, -360 degrees, and 360 degrees, there will be no difference in appearance, and the driver cannot Intuitively recognize the angle of the steering wheel from the appearance of the steering wheel, and it is impossible to know the situation of the vehicle in time
In addition, when the driver just enters the vehicle, the driver cannot obtain the angle information of the vehicle, which is very inconvenient for human-computer interaction, and sometimes even easily causes vehicle accidents

Embodiment Construction
[0019] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, in which the same reference numerals denote the same elements.
[0020] Usually, the space in the steering wheel is limited and the angle sensor usually includes three parts: the upper casing, the lower casing, and the angle sensing device, so an angle sensor with a thickness of about 10 mm cannot be installed in the steering wheel. Considering that the clock spring is usually installed under the steering wheel, and the clock spring also has an upper and lower housing, the two parts of the angle sensor are arranged between the upper housing of the clock spring and the lower housing of the clock spring, that is, the clock spring and the angle sensor share a common Upper and lower shells. Thereby the purpose of realizing the angle measurement of the steering wheel in the limited interior space of the vehicle is achieved.

The invention provides a steering wheel angle measurement device, a steering wheel angle reminding device and an automobile. The steering wheel angle measurement device comprises a clock spring and an angle induction device, an upper casing of the clock spring rotates with a steering wheel at an identical angular speed through a connecting piece, and the angle induction device is arranged on a lower casing of the clock spring and used for measuring the angle of the steering wheel. The angle of the steering wheel can be measured through the steering wheel angle measurement device. Furthermore, when the automobile is just started, if the steering wheel is in misalignment, a driver can be reminded.
Description
technical field [0001] The invention relates to a detection technology, in particular to a steering wheel angle measuring device, a steering wheel angle reminding device and an automobile comprising the steering wheel angle measuring device or the steering wheel angle reminding device. Background technique [0002] When the steering wheel of the vehicle is driving or parking, the steering wheel angle is often misaligned. When the steering wheel is in the three positions of 0 degrees, -360 degrees, and 360 degrees, there will be no difference in appearance, and the driver cannot Intuitively recognize the angle of the steering wheel from the appearance of the steering wheel, and it is impossible to know the situation of the vehicle in time. In addition, when the driver just enters the vehicle, the driver cannot obtain the angle information of the vehicle, which is very inconvenient for human-computer interaction, and sometimes even easily causes vehicle accidents.
