Careless accelerator stamping error correcting system fast executing emergency braking through steering system oil pump

Abstract

The invention discloses a careless accelerator stamping error correcting system fast executing emergency braking through a steering system oil pump. The careless accelerator stamping error correcting system fast executing emergency braking through the steering system oil pump can directly convert a careless accelerator stamping signal to the process that a braking machine is driven to execute braking motion. A braking oil outlet pipe of a master braking pump is communicated with a steering oil outlet pipe of a normal-state high-pressure oil tank of a hydraulic power-assisted steering system through an emergency braking oil pipe; an oil outlet electric valve is connected to the emergency braking oil pipe in series; a backflow-preventing electric valve is connected in the braking oil outlet pipe in series; a switch controller is further and respectively connected with the oil outlet electric valve and the backflow-preventing electric valve. The careless accelerator stamping error correcting system fast executing emergency braking through the steering system oil pump has the advantages that emergency braking motion is directly controlled by a careless accelerator stamping sensor without braking pedals or the master braking pump and is therefore fast, and car accidents caused by careless accelerator stamping can be better reduced and can be even avoided. The braking pedals do not need pulling, and the careless accelerator stamping error correcting system fast executing emergency braking through the steering system oil pump is not limited by car types and is installed in a unified mode.

Description

technical field [0001] The invention belongs to the technical field of a steering system, an automobile gas pedal system and a braking system, in particular a system capable of directly converting a misstepped gas pedal signal into a driving brake mechanism to perform a braking action. Background technique [0002] In the error correction system for wrongly stepping on the accelerator in the prior art, it is necessary to pull the brake pedal and the brake pedal to drive the brake master cylinder to perform the emergency braking action. Time delay is unfavorable for mitigating, preventing accident from stepping on the gas pedal by mistake. The mechanism for pulling the brake pedal is more complicated, and different vehicle models often require different mechanisms for pulling the brake pedal, so it is difficult to realize a unified error correction system for incorrectly stepping on the accelerator regardless of the vehicle type. [0003] The error correction system for wron...

Problems solved by technology

[0002] In the error correction system for wrongly stepping on the accelerator in the prior art, it is necessary to pull the brake pedal and the brake pedal to drive the brake master cylinder to perform the emergency braking action. Time delay is not conducive to reducing and preventing car accidents caused by accidentally stepping on the accelerator

The mechanism for pulling the brake pedal is relatively complicated, and different models often require different mechanisms for pulling the brake pedal.

[0003] The error correction system of the prior art needs to drive a special motor with the signal of the wrong step on the accelerator, and then use the special motor to pull the brake pedal. The accuracy of the mechanical displacement transmission cannot be guaranteed for a long time, which will affect the reliability of correcting the brake for the wrong step on the accelerator
