Brake pedal touch simulation device based on driving simulator

Abstract

The invention discloses a brake pedal touch simulation device based on a driving simulator. The brake pedal touch simulation device comprises a magnetic powder clutch, a swing arm, a connecting rod, aspring and a brake pedal, the brake pedal is rotationally arranged at the lower end of a longitudinal fixing rod, a groove allowing one end of the connecting rod to be inserted is formed in the surface of the side, facing the magnetic powder clutch, of the brake pedal, the spring is arranged in the groove and elastically connected with the end, stretching into the groove, of the connecting rod, and the other end of the connecting rod is rotationally connected with the swing end of the swing arm. The fixed end of the swing arm is fixedly arranged on an output shaft of the magnetic powder clutch; and a control signal input end of the magnetic powder clutch is connected to a control signal output end of a controller of the driving simulator. On the premise that an original vehicle braking system is not needed, the rigidity and damping feeling close to those of real vehicle operation are simulated.

Description

technical field [0001] The invention relates to a brake pedal tactile sensation simulation device, in particular to a brake pedal tactile sensation simulation device based on a driving simulator. Background technique [0002] At present, with the proposal of the concept of personalized driving of automobiles, in order to fully understand the personality characteristics of drivers, a large number of data collection experiments under different working conditions need to be carried out. With limited working conditions, it is necessary to provide drivers with a driving simulator that is close to the real car and simulate the feeling of real driving. The existing related technologies often have two major problems: one uses the spring to simulate the stiffness of the pedal, which cannot simulate the damping feeling when the pedal is stepped on. The dynamic pipeline and the brake assembly can basically simulate the tactile feeling of the actual vehicle operation, but due to the us...

AI Technical Summary

Problems solved by technology

There are often two major problems in the existing related technologies: one uses the spring to simulate the stiffness of the pedal, which cannot simulate the damping feeling when the pedal is stepped on, and the tactile feeling when pedaling is quite different from that of the real car; The dynamic pipeline and brake assembly can basically simulate the tactile feeling of real vehicle operation, but due to the use of the original vehicle's braking system, the mechanism is relatively complicated, which is not conducive to the design of equipment space layout

[0003] The existing new brake pedals and sensory simulators used for driving simulators have deficiencies in force feedback and structure. The Chinese patent publication number is CN105270375A, and the publication date is 2016.01.27. The name of the invention is brake by wire and pedal. In the force feedback system and braking method, the hydraulic feedback method is used. When the fluid replenishment device is working, if the fluid replenishment speed is set too fast, the pressure loss during the fluid flow will be too large, which will lead to a sudden change in the pedal feedback force and cause the driver to stop. Misjudgment of braking force, if the fluid replenishment speed is set slowly, it will lead to poor timeliness of feedback, and the driver’s operation cannot get timely feedback

As a result, the driver cannot obtain pedal force feedback well

Another example is the Chinese Patent Publication No. CN104670188A, the publication date is 2015.06.03, and the title of the invention is an automobile brake pedal structure with adjustable lever ratio. Adjusting the pedal force by adjusting the position of the pedal lever will change the position of the pedal. The height from the floor has a certain impact on the driver's habitual driving operation
