Problems solved by technology

[0003] 1. The spatial position of the pedals is fixed, and it is difficult to meet the needs of different percentile drivers. For drivers who are particularly tall and short, it is easy to feel driving fatigue. In more serious cases, it will be harmful due to the slow switching between pedals. driving safety
[0004] 2. At present, there is no unified national and industry standard for the setting of the pedal angle. All automobile companies design based on the company's experience data, so it cannot meet the driving needs of everyone.
Existing vacuum boosters and electric boosters have a small adjustment range for the pedal feel, making it difficult to meet the requirements of different drivers

Embodiment Construction

[0031] A three-pedal adjustment mechanism based on leg surface myoelectric signals, including an X-direction slide rail, a Y-direction slide rail, a Z-direction electric push rod vertically fixed on the Y-direction slide rail slider, and a pedal that can relatively rotate The upper and lower arms, the gear assembly between the upper and lower arms, the pedal inclination adjustment mechanism, and the central processing unit 34. The central processing unit 34 can process and analyze the myoelectric data collected from the outside, and finally recommend the optimal pedal configuration scheme according to different human bodies. The central processing unit 34 can satisfy the use of the following schemes: one: the driver inputs physical parameters such as height and weight, and the central processing unit 34 can automatically adjust the pedal position, inclination and pedal manipulation feeling most suitable for the driver's human body percentile. Two, the surface electromyographic ...

Abstract

The invention discloses a three-pedal adjusting mechanism based on leg surface electromyographic signals. The three-pedal adjusting mechanism comprises an X-direction sliding rail, a Y-direction sliding rail, a Z-direction electric push rod vertically and fixedly arranged on a Y-direction sliding rail sliding block, pedal upper and lower arms capable of rotating relatively, a gear assembly betweenthe upper arm and the lower arm, a pedal inclination angle adjusting mechanism and an external central processing unit. The central processing unit can carry out processing and analysis according toelectromyographic data collected from the outside. The requirements of drivers with different percentile for the spatial position, inclination angle and manipulation feeling of the pedal are met, andan optimal pedal configuration scheme is recommended according to different human bodies. A clutch pedal adjusting assembly, a brake pedal adjusting assembly and an accelerator pedal adjusting assembly have the same adjusting mode.

Description

technical field [0001] The invention relates to the field of automobile control, in particular to a multi-parameter adjustable three-pedal mechanism based on leg myoelectric signals. Background technique [0002] As a component that the driver is in direct contact with, the rationality of the layout of the pedals and the comfort of operation play a very important role in improving driving safety and reducing human fatigue during long-distance driving. As a mature and reliable technical means, the muscle surface signal can quantitatively and accurately analyze the strain state of the muscle. Therefore, introducing the analysis of the electromyographic signal into the parameter design of the pedal can more effectively meet the individual needs of the driver and improve driving performance. Safety factor. The previous pedal structure design mainly has the following problems: [0003] 1. The spatial position of the pedals is fixed, and it is difficult to meet the needs of diff...
