Automobile with semi-automatic error correction braking system with inward rotating solenoid valve having fixed rotation angle

Abstract

The invention relates to an automobile with a semi-automatic error correction braking system with an inward rotating solenoid valve having fixed rotation angle, in particular to a semi-automatic safe automobile which can change an accidental step on an accelerator into an automatic braking and a manual resetting. A sensor of the error correction braking system is disposed at a position near an accelerator pedal. A pulling cord is connected to the outer surface of a central rotary shaft of the solenoid valve with an inner fork-shaped rotator. The other end of the pulling cord is connected with a braking pedal and a braking linkage device so as to form the automobile with the error correction braking system. The automobile with the semi-automatic error correction braking system with the inward rotating solenoid valve having the fixed rotation angle has the advantages that response speed from detecting the accidental step on the accelerator to correcting the accidental step into braking is fast, the solenoid valve which drives a brake is accurate in operation, full-automatic error correction braking can be achieved with no rotator locking, and a braking state can be maintained for a long time without power consumption until a driver manually restores a state before the system starts so that the automobile can be driven normally again.

Description

technical field [0001] The invention belongs to the technical field of braking of automobiles, in particular, it can transform the human operation of stepping on the gas pedal by mistake into an automobile using an error correction braking system for automatic braking. Background technique [0002] Chinese patent 200510022077.X "Accelerator System Device with Annunciator" provides a device that can judge whether the accelerator action is correct or wrong before determining whether to remedy and brake, so that the accelerator can be used for both braking and acceleration. Motor vehicle accelerator pedal system. It is characterized in that an annunciator is arranged on any one of the accelerator pedal, the linkage device and the vehicle body device. The annunciator is connected with the electric valve that can cut off the engine oil circuit and the electric valve on the wheel brake. This technology proposes to use electronic settings to perceive the action of misstepping the...

Problems solved by technology

One of the disadvantages of this technology is that the practicability of the mechanical device for starting the car brake is not strong

[0003] Chinese patent application 201001130092.4 "A Device for Automatically Correcting Misstepped Accelerators into Brakes with the Coordination of Electric Appliances and Machinery" discloses a device including a sensor, a signal analyzer and a brake activation mechanism. There are many electronic devices, and the reliability is reduced; the second disadvantage is that in the brake activation mechanism, the circular motion of the solenoid valve is changed into the reciprocating motion of the brake cable, and the straight rack is used to change the motion mode, because the straight tooth must be kept The reciprocating motion of the bar positioning requires a frame to fix the relative position of the solenoid valve and the straight rack. This frame is bulky and difficult to find a suitable location for installation. Moreover, the structure is complex, the cost is high, the reliability is not good, and the practicability is not strong. , and the solenoid valve in the brake activation mechanism maintains the locked-rotor state of the brake, which is easy to damage the solenoid valve
