A device and method for remediating accidental stepping on the accelerator pedal of an automobile

Abstract

The invention belongs to the technical field of automobiles, and discloses a device and method for remediating accidental stepping on the accelerator pedal of an automobile. Step on the recovery mechanism, and the wrong step recovery mechanism includes: a moving transmission shaft that can reversely rotate with the accelerator pedal, and a detachable reverse transmission assembly is connected between the moving transmission shaft and the accelerator pedal; When the reverse transmission assembly is driven, the connecting sleeve rotates in the same direction as the moving transmission shaft, and one end of the moving transmission shaft extends into the connecting sleeve and is slidably connected with the connecting sleeve; A fixed transmission shaft at one end, the fixed transmission shaft is rotatably connected with the connecting sleeve, and the fixed transmission shaft is driven in the same direction as the brake pedal; in summary, the same process when accidentally pedaling is realized by using the power storage transmission method Brake to ensure the remedial effect.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to a device and method for remediating accidental stepping on an accelerator pedal of an automobile. Background technique [0002] A patent (CN107031396B) proposes a remedial device and a control method for wrongly stepping on the accelerator pedal of an automobile. In this invention, it is proposed to judge whether the accelerator pedal is misoperated by detecting the opening of the accelerator pedal, and the remedial operation after the judgment is to prevent Accelerator signal to keep the engine idling and not turn off, so as to achieve the purpose of car deceleration; however, in the actual driving process, especially in the event of an emergency traffic accident, it is not enough to achieve car deceleration only by engine idling. Therefore, it is necessary to carry out corresponding emergency braking in order to reduce the probability of traffic accidents to the...

[0002] A patent (CN107031396B) proposes a remedial device and a control method for wrongly stepping on the accelerator pedal of an automobile. In this invention, it is proposed to judge whether the accelerator pedal is misoperated by detecting the opening of the accelerator pedal, and the remedial operation after the judgment is to prevent Accelerator signal to keep the engine idling and not turn off, so as to achieve the purpose of car deceleration; however, in the actual driving process, especially in the event of an emergency traffic accident, it is not enough to achieve car deceleration only by engine idling. Therefore, it is necessary to carry out corresponding emergency braking in order to reduce the probability of traffic accidents to the greatest possible extent.

[0003] In the prior art, most of the simulation actions of "depressing the brake pedal" are realized by means of motor-driven push rods or pull wires, but this method has the defects of long execution time and slow corresponding speed, so it still cannot meet the actual needs; In addition, in the patent (CN104890512B), a vehicle anti-misstepping pedal system is proposed, which is an auxiliary braking method in which the brake pedal and the accelerator pedal are linked. Although this method can quickly achieve the effect of emergency braking, the In the method, the angular acceleration of stepping on the accelerator pedal is used to judge the misstepping, which is prone to misjudgment; for example, in the process of overtaking, the driver will also quickly step on the accelerator pedal. The emergency braking of the car is more likely to cause traffic accidents such as rear-end collisions

[0004] It can be known from the above disclosed patents that the above-mentioned existing problems can be effectively solved by combining the method of detecting the opening of the accelerator pedal mentioned in the patent (CN107031396B) with the linkage auxiliary braking proposed in the patent (CN104890512B); , after the above two methods are combined, there is still the following problem: when the opening of the accelerator pedal exceeds the set threshold (generally 90%), the pedaling process of the accelerator pedal is close to the end, if the linkage is executed in this state, at most Only 10% of the pedaling process can be achieved, which greatly reduces the braking range and affects the emergency braking effect
