Problems solved by technology

The first disadvantage of this technology is that in the continuously changing pressure signal felt by the annunciator, when the signal acquisition device for judging and taking out the false accelerator pedal signal is faulty, it may make an error in the judgment of the false accelerator pedal signal, resulting in the failure of the system. poor reliability
The second disadvantage of this technology is to use the signal output line to control the electric valve, and use the electric valve to shut off the engine oil supply pipe, ignition circuit, motor power supply, etc. of the vehicle, so that the driver has a long time to step on the accelerator by mistake until the vehicle is stopped. The wrong trip is far away, and this slow response is not conducive to preventing car accidents from happening
The third disadvantage of this technology is to use the signal output line to control the electric valve, and use the electric valve to cut off the engine oil supply pipe, ignition circuit, motor power supply, etc. of the vehicle, so that the engine will stop rotating and work completely, causing the brake system and steering of the car to be damaged. system, anti-skid and other safety systems have all stopped working, so shutting off the engine of the vehicle with a false accelerator pedal signal is not conducive to performing error-correcting emergency braking when there is a false accelerator pedal
[0005] In his patent application 201110030092.4 "A Device for Automatically Correcting Misstepped Accelerators to Brakes with Electric Appliances and Machinery", the applicant disclosed a device including a sensor, a signal analyzer and a brake activation mechanism. There are many microelectronic devices for stepping on the accelerator signal, and the reliability is reduced; the second disadvantage is that in the brake starting mechanism, the circular motion of the motor is changed into the reciprocating motion of the brake rope, and the straight rack is used to change the motion mode, because it needs To ensure the reciprocating motion of the straight rack positioning, a frame is required to fix the relative position of the motor and the straight rack. This frame is bulky, difficult to find a suitable location for installation, and has a complex structure, high cost and poor reliability.
Microelectronic circuits are prone to signal drift and poor reliability

Abstract

The invention discloses a gear-rack-type accelerator misstep correcting system for controlling forward and reverse rotation of a motor by using a relay, belongs to the technical field of automobile brake systems, and particularly discloses an accelerator misstep correcting brake system capable of directly converting an accelerator misstep signal into a mechanical brake driving signal. A sensing switch K0 is connected with and controls a reverse power supply relay controller; the electrical controller controls a motor assembly with a limit switch and outputs electrical energy to the motor assembly; a gear rack of the motor assembly drives a stay wire with an outer sleeve; the motor assembly can switch off a reverse power supply circuit of the reverse power supply relay controller; and the stay wire transfers the rotational displacement of the motor in the motor assembly to an automobile brake pedal so as to achieve the control of the sensing switch K0 to the automobile brake pedal. The gear-rack-type accelerator misstep correcting system for controlling the forward and reverse rotation of the motor by using the relay has the advantages as follows: the reliability of a reverse power supply switch formed by combining relay switches is far superior to that of a microelectronic controller; and three states of the accelerator misstep correcting system are controlled, so that the controller of the accelerator misstep correcting system has extremely high reliability.
