Vehicle, magnetorheological fluid type vehicle shock absorbing seat control device and method thereof

Abstract

The invention relates to a vehicle, a magnetorheological fluid type vehicle shock absorbing seat control device and a magnetorheological fluid type vehicle shock absorbing seat control method. The magnetorheological fluid type vehicle shock absorbing seat control device comprises a seat body, a damping assembly, an elastic sealing connection component, a box body, an acceleration sensor and an ECU, wherein the damping assembly comprises a damping plate which is fixedly connected to the bottom part of the seat body in a perpendicular manner, and a damping hole penetrating the damping plate; a magnetorheological fluid is internally packaged in the box body, and the box body is in sealing connection with the damping assembly by means of the elastic sealing connection component; the damping assembly suspends in the magnetorheological fluid and can be kept in a state of separation from the inner surface of the box body; the acceleration sensor is used for acquiring seat acceleration information and transmitting the seat acceleration information to the ECU; and the ECU is used for receiving the seat acceleration information acquired by the acceleration sensor, and calculating a current control quantity applied to the magnetorheological fluid according to the seat acceleration information, so as to control damping characteristics of the magnetorheological fluid flowing through the damping hole. The magnetorheological fluid type vehicle shock absorbing seat control device can realize the shock absorption of the seat body, and is conductive to enhancing the comfort of a passenger sitting on the seat.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle, a magneto-rheological fluid type vehicle vibration-damping seat control device and a method thereof. Background technique [0002] As for seat comfort, studies have shown that the vibration of vehicle seats will have a very adverse effect on people's physiological and psychological reactions. Long-term exposure to low-frequency and high-intensity vibrations will endanger the driver's cardiovascular system, nervous tissue, Muscle tissue will cause the driver's hearing loss and unresponsiveness, increase the physical and mental burden of the driver, and more seriously, increase the probability of traffic accidents. The car will vibrate in all directions during driving, so the seat will vibrate in all directions accordingly, which has a great comfort problem, and most of the current car damping seats focus on the vibration reduction in the up and down directions , there...

[0002] As for seat comfort, studies have shown that the vibration of vehicle seats will have a very adverse effect on people's physiological and psychological reactions. Long-term exposure to low-frequency and high-intensity vibrations will endanger the driver's cardiovascular system, nervous tissue, Muscle tissue will cause the driver's hearing loss and unresponsiveness, increase the physical and mental burden of the driver, and more seriously, increase the probability of traffic accidents

The car will vibrate in all directions during driving, so the seat will vibrate in all directions accordingly, which has a great comfort problem, and most of the current car damping seats focus on the vibration reduction in the up and down directions , there are few seats capable of multi-dimensional vibration reduction; secondly, the vibration-absorbing seats at this stage mostly use a mechanical mechanism composed of connecting rods and spring dampers. And seat abnormal sound and other problems
