Friction type automobile driving anti-interference device

Abstract

The invention provides a friction type automobile driving anti-interference device. The anti-interference device comprises an electronic control unit of an automobile, wherein an input interface of the electronic control unit is connected with a piezoelectric sensor, an infrared sensor and a speed sensor; the infrared sensor is arranged in a cab area and is connected with an input end of a single-chip microcomputer of the electronic control unit; the piezoelectric sensor is arranged at a steering wheel at the upper end of a steering column and is connected with the input end of the single-chipmicrocomputer of the electronic control unit; an output end of the single-chip microcomputer of the electronic control unit is connected with an electromagnetic valve, and the electromagnetic valve is connected with a hydraulic cylinder; and a hydraulic cylinder piston of the hydraulic cylinder is connected with one end of a friction plate in a friction type locking mechanism, the friction plateis arranged on a steering shaft connected with the steering wheel, and tension is provided by a spring. According to the friction type automobile driving anti-interference device, when a passenger cardriver encounters the situation that a non-rational passenger pulls and grabs the steering wheel, the steering column can be locked, a hazard warning lamp and a linkage braking system are started, the direction controlling by the driver is assisted, deceleration parking is realized, and driving safety is guaranteed.

Description

technical field [0001] The invention belongs to the field of vehicle driving state detection, and in particular relates to a friction-type vehicle driving anti-interference device. Background technique [0002] In the prior art, the main research direction of anti-jamming system for passenger cars is anti-electromagnetic interference and anti-cross-interference, which is dedicated to solving the interference of electromagnetic interference on vehicle electronic equipment through conduction and radiation, as well as anti-collision radar, anti-lock braking system, etc., but for External human factors such as passengers, especially human interference when the driver is driving and cannot divert his attention, such as passengers grabbing the steering wheel, have no relatively systematic and concentrated research programs and results. Contents of the invention [0003] The purpose of the present invention is to provide an anti-interference device for driving a car, which can tu...
