Protective control device in case of mistakenly stepping on accelerator in stead of brake

Abstract

The invention relates to a protective control device in a case of mistakenly stepping on an accelerator instead of a brake, comprising a control circuit and an accelerator pedal mechanism. The protective control device is characterized in that the control circuit is provided with a power module and a single-chip microcomputer control circuit; the input end of the single-chip microcomputer control circuit is respectively connected with at least two accelerator stepping signal sensing probes; the accelerator stepping signal sensing probe A and the accelerator stepping signal sensing probe B are arranged on the bottom surface of an accelerator pedal along the length direction of the accelerator pedal; and the output end of the single-chip microcomputer control circuit is respectively connected with oil control valves and gas control valves, wherein the oil control valves are connected on an oil supply pipeline for an engine in series and the gas control valves are connected on a gas supply pipeline for a pneumatically operated brake mechanism in parallel. The mechanical structure of the protective control device, which is combined with a circuit module, can efficiently and automatically break off an oil channel, implement braking and give a sound-light alarm in the case of mistakenly stepping on the accelerator, thus effectively avoiding the accelerator from being mistakenly stepped and protecting the safety of personnel and property inside and outside a car.

Description

technical field [0001] The invention relates to a protection control device for accidentally stepping on a brake to become an accelerator, and belongs to the field of automobiles. . Background technique [0002] With the development of the economy, more and more people drive cars, but for those who have just learned to drive, it often happens that the gas pedal is mistaken for the brake, which greatly increases the danger of driving, and not only It is the people who just learned to drive, for those who have been driving for a long time, accidental stepping events will also occur in emergency situations, so many inventions and creations to prevent the accelerator pedal from being stepped on by mistake have occurred in the society. However, the inventions currently used for stepping on by mistake are either complicated in mechanical structure or poor in reliability. Therefore, how to solve the above problems is the research object of the present invention. Contents of the...
