Description

Steering status indicator

The present invention relates to an apparatus for displaying a steering state of a vehicle so that the driver can know the steering state of the vehicle, and more particularly, to an apparatus for displaying the rotation state of the steering wheel by being attached to the steering wheel of the vehicle and rotating together.

In a vehicle equipped with a steering device in which a steering wheel in a driver's seat is rotated about its axis in the circumferential direction to control the traveling direction of the vehicle, the rotation angle of the vehicle wheel and the rotation of the steering wheel in order to reduce the operating force of the steering wheel. Make sure the angles do not match and have a constant ratio. For example, in the case of a passenger car, the steering device is configured such that the steering wheel is approximately rotated two times in order to rotate the vehicle wheel as far as possible in one direction. This ratio is larger for larger vehicles. Therefore, in operation of the steering wheel, it is sometimes difficult for the driver to know how much the steering wheel has rotated in the neutral position (the state in which the vehicle wheel is straight). For example, if the steering wheel is rotated 360 degrees, the driver may think that the steering wheel is neutral or rotated 720 degrees, so the driver may turn his head out of the driver's seat out of the window to check the steering wheel steering. Frequent checks are necessary. In particular, in such a situation, when parking in a narrow place, the right turn and the left turn are alternately repeated several times, which makes it difficult to grasp the neutral state of the vehicle wheel.

As a method for solving the above problems, various methods have been proposed in the past. These methods usually take the form of attaching a sensing sensor to the steering wheel of a vehicle wheel and monitoring the sensing result in the cockpit of the driver's seat. As one example, there was a method in which a variable resistor in accordance with the rotational state of the shaft is installed in a steering wheel or a steering gear box and the resistance value is converted into the steering angle of the vehicle wheel to monitor the instrument panel.

However, the above method has to change the structure of the steering wheel or steering gear, and to install a separate display means on the instrument panel is expensive and complicated to install, there is a disadvantage that complicates the structure of the vehicle, There is a fear of malfunction in the variable resistor or the display means, and when the display means is installed on the instrument panel, it is inconvenient for the driver to observe it from time to time.

Accordingly, the present invention has been made to solve the above problems, and is intended to provide a steering state display device that is simple in structure, easy to manufacture and inexpensive, and which can be installed with little change in the structure of the vehicle.
