A collision adaptive foot rest system and its control method

Abstract

The invention proposes a collision adaptive footrest system and a control method thereof, which is comfortable to use and can avoid injury to passengers' feet during a collision, and specifically includes a footrest body and a footrest installation structure composed of a bottom plate and a vertical plate , the two ends of the foot rest board body are respectively movably connected with the bottom plate and the vertical plate; the foot rest board body is provided with a driving device for driving the foot rest board body to move, so as to change the angle between the foot rest board body and the bottom plate; the key lies in the top of the foot rest board body. There is a pressure sensor on the surface, and the pressure sensor and the driving device are all connected with the control unit. The invention can timely adjust the state of the foot rest board according to the force of the occupant's feet during the driving process, so as to maintain the comfort of the occupant's feet, and at the same time, it can solve the damage to the lower limbs of the occupant caused by the large intrusion of the front cabin during the collision process, especially It can reduce the impact force on the dummy's legs during the invasion process of the front wall, and prevent the dummy's legs from being sprained due to uneven force in the collision.

Description

Technical field[0001]The present invention belongs to the technical field of automobile collision safety, and specific to the hacking system and its control method thereof.Background technique[0002]The driver's hiking board can provide the driver to the foot support, which plays a comfortable effect on the driver during driving, but due to the complexity of road traffic, various collision forms occur in real life, such as drivers. The bias collision on the side will cause a large extent of the crew invasive, so the lower limbs of the occupant have an uncontrolled harm. At present, the vastly in the market uses foam to alleviate the damage of the occupant when the collision is mitigated, but due to the complexity of the collision and the restriction of the occupant space, the rest is not effective in reducing the occupant's lower limbs during the occupant. Injury caused by the impact, especially during the collision, the pedicure of the occupant is uneven, and cannot prevent the coll...

Problems solved by technology

[0005] The occupant steps on the body of the footrest, and the pressure applied to the body of the footrest is transmitted to the control unit by the pressure sensor. The control unit detects the above-mentioned pressure value in real time during driving. When the pressure value is too large, it means that the force on the occupant's foot large, poor occupant comfort (there may even be a risk of injury to the occupant's feet due to sudden braking, collision, etc.), the control unit quickly changes the angle between the footrest and the bottom plate through the driving device, thereby synchronously adjusting the occupant's foot In order to reduce the force on the occupant's feet, the comfort of the occupant is improved, and the foot sprain caused by the uneven force on the occupant's foot during the complex collision process, and the foot space caused by insufficient foot space are overcome.
