Problems solved by technology

[0004] However, in the prior art, the road feeling simulator cannot limit the steering wheel. When the steering-by-wire system is powered off or fails, the steering wheel may rotate freely, and the range of the steering wheel angle sensor is generally Three turns on the left and right, the steering wheel of the road feeling simulator in the infinite position can easily exceed the range of the angle sensor, which will cause the angle sensor to fail after the steer-by-wire system is powered on again
However, the angle sensor cannot be automatically zeroed after the range is exceeded, and manual recalibration is required, which is very inconvenient to operate

Abstract

The invention discloses a road feel simulator and belongs to the technical field of automobiles. The road feel simulator comprises a limiting part and a steering wheel end input shaft; the limiting part comprises a steering shaft, a sliding nut, a first limiting piece and a second limiting piece; one end of the steering shaft is connected with the steering wheel end input shaft so that the steering wheel end input shaft and the steering shaft can rotate at the same time; the sliding nut is in threaded connection with the steering shaft, and the sliding nut and the steering shaft form a lead screw nut pair; the first limiting piece is arranged on the steering shaft and located on one side of the sliding nut; the second limiting piece is arranged on the steering shaft and located on the other side of the sliding nut; when the steering shaft rotates around the axis of the steering shaft, the sliding nut can linearly move along the steering shaft to abut against the first limiting piece orthe second limiting piece so as to limit the rotating angle of the steering shaft. The rotation angle of the steering wheel can be limited, and the situation that rotation of the steering wheel exceeds the range of a rotation angle sensor is avoided.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a road feeling simulator. Background technique [0002] In recent years, with the continuous development of automotive electronic control technology, the steer-by-wire system, as a new generation of automotive steering system, has become more and more popular in the market. [0003] In the prior art, the steer-by-wire system cancels the mechanical connection structure between the steering wheel and the wheels, so that the driver cannot feel the reaction torque of the steering wheel when turning, and thus cannot make accurate judgments on road surface information. Therefore, the steer-by-wire system is generally equipped with a road feeling simulator to simulate the force feeling of the driver when steering and the road condition information feedback from the road surface to the driver. [0004] However, in the prior art, the road feeling simulator cannot limit the steering w...
