Emergency braking device anti-misstep device

Abstract

Disclosed is a mis-tread preventing device for emergency stop, belong to autocontrol technical field. The input port of a signal processor is connected to the output port of pressure difference electrical signal of a controllable magnet valve; the output port of the signal processor is connected to the input port of a controller; the two output ports of the controller are connected to the control pole of two electronic switches; the anode and the cathode of the first electronic switch are connected in series in a DC power supply loop for the controllable magnet valve; the controllable magnet valve is disposed at the upper range of the foot pedal accelerograph in a gasoline pipe of the automobile. Gasoline supplied to the automobile first goes through the controllable magnet valve, then passes the foot pedal accelerograph and at last goes to the cylinder of the engine. The anode and the cathode of the second electronic switch are connected in series in a DC power supply loop for an electricity powered handspike; the top of the electricity powered handspike is mechanically connected to the force arm at the lower part of the pedal rod of an arrester in a mode that the handspike and the arrester can rotate in a plane within 90 degree. The invention can prevent accidents and safeguard the safety of people as well as transportation vehicles.

Description

technical field [0001] The invention relates to a safety protection device in the driving process of an automobile in the technical field of automatic control, in particular to a device for preventing a driver from stepping on an accelerator by mistake when a car is suddenly braked. Background technique [0002] With the development of world economy and science and technology, traffic accidents occur frequently while automobiles are becoming more and more popular. There are not a few people who cause major accidents due to the misoperation of car drivers, which needs to be avoided by improving the corresponding technical level. Among them, during the driving process of the car, there is a sudden special situation ahead, such as: a person suddenly crosses the road, the vehicle in front brakes suddenly, etc., because the driver is nervous or unable to react in time, the emergency brake should be performed, but the accelerator is stepped on by mistake, so Major accidents such ...

AI Technical Summary

Problems solved by technology

However, the biggest technical defect of the above-mentioned technology is that the sensing of "detecting the action signal of stepping on the accelerator by mistake" is obtained through the "electromagnetic sensor".

This is an indirect sensing of the opening state of the accelerator. It only senses the displacement of the accelerator pedal, but does not directly sense the actual oil flow of the accelerator. The reliability is low. Once the error of the output signal of the "electromagnetic sensor" is caused by the change of the mechanical clearance of the pedal, the expected technical effect will not be achieved.
