Electrohydraulic automobile emergency braking mistakenly-stepping prevention accelerator pedal device

Abstract

The invention provides an electrohydraulic automobile emergency braking mistakenly-stepping prevention accelerator pedal device which comprises an accelerator pedal and a brake pedal, wherein an electrohydraulic mistakenly-stepping linkage device is arranged on the accelerator pedal; the electrohydraulic mistakenly-stepping linkage device comprises a push rod, a piston cylinder, a membrane, a control valve and a hydraulic storage tank; one end of a push rod is connected with a hinged shaft of the accelerator pedal, and the other end of the push rod is hinged with a piston of the piston cylinder; the hydraulic storage tank is arranged above a piston cylinder body, and the control valve is arranged between the cylinder body and the hydraulic storage tank; the membrane is arranged in the cylinder body; an assistance motor circuit on-off switch is arranged on the membrane; an assistance motor circuit contact is arranged at the right end of the cylinder body; one end of the assistance motor circuit contact is in series connection with a storage battery low voltage loop, and the other end of the assistance motor circuit contact is connected with an assistance motor; a motor reducer is arranged on the assistance motor; and the motor reducer is connected with a brake pedal arm through a drawing wire. The device obeys normal operation; the structure is simple, the cost is low, and the braking is accurate; and travelling accidents caused by mistakenly stepping the accelerator pedal can be effectively avoided, and the safety of an automobile is improved.

Description

technical field [0001] The invention relates to a hydraulic electric control device for preventing a driver from stepping on an accelerator pedal by mistake during emergency braking of an automobile. Background technique [0002] When the car brakes in an emergency, the driver easily steps on the accelerator pedal by mistake, which causes more and more traffic accidents, which is very unsafe. However, the current structural design of automobiles cannot prevent the adverse consequences brought by such misoperations. Contents of the invention [0003] In order to solve the defect in the prior art that the accelerator pedal is easily stepped on by mistake during emergency braking of an automobile, the present invention proposes a hydraulic-electric vehicle emergency braking anti-misstepping on the accelerator pedal device. [0004] Therefore, the technical solution of the present invention is: a hydraulic-electric vehicle emergency braking anti-misstepping accelerator pedal ...
