Prompting system for changing touch sense of vehicle steering wheel

Abstract

The invention discloses a prompting system for changing the touch sense of a vehicle steering wheel. The system comprises a touch sense change generating component A, a touch sense change driving component B, a connecting component C for connecting the component A with the component B, and an optional connecting component D for connecting the component B with a vehicle power supply and a bus signal. The component A is an inflatable or liquid-filled light and thin touchable component composed of an elastic hose or a thin film, and can generate perceptible deformation according to air pressure or hydraulic pressure changes after being driven. The component B is provided with a controller and control software, and when the component B obtains running state data of a vehicle from a bus through a wired connection component D or wireless connection, the component B sends out a driving instruction according to conditions preset by the control software to drive the air pressure or hydraulic pressure change of the touch sense change generating component A, therefore, the touch sense change of the steering wheel to the hands of the driver is generated, the driver can be prompted, the driving safety is promoted, and the personal and property safety is guaranteed.

Description

technical field [0001] The invention belongs to the field of vehicle auxiliary technology, belongs to the application field of human-computer interaction technology in the field of vehicle and aircraft driving, and particularly relates to a device and system with a steering wheel-like operation interface. Background technique [0002] The steering wheel is an essential driving control device for vehicles and aircraft. The driver must master the use of the steering wheel proficiently, and the hands cannot leave the steering wheel during driving. Mastering the operation of the steering wheel is a skill that every driver spends a lot of time mastering. [0003] The control of the steering wheel generally only has to be rotated, and it is passively operated, without feedback and prompting functions for the driver. Although vehicles with certain automatic driving functions can not require the driver to actively operate the steering wheel in most cases, they all require the driv...
