Problems solved by technology

Since the traditional mechanical connection and hydraulic parts are canceled in the control-by-wire technology, the driver cannot directly perceive the acceleration of the vehicle or the force feedback of the pedal from the control-by-wire system. And the pedal feedback force feeling when braking, realize the information interaction between man and machine, so that the driver can accurately perceive the control effect of the vehicle

Abstract

The invention belongs to the field of intelligent driving vehicles, and relates to a pedal force feeling simulation device based on magnetorheology. It includes a first transmission shaft and a second transmission shaft arranged in parallel, the first transmission shaft and the second transmission shaft are connected by a continuously variable transmission mechanism; The driving wheel and the driven wheel on the second transmission shaft, and the connecting belt connecting the driving wheel and the driven wheel; the first transmission shaft is provided with a torsion spring, and a pedal installed on the first transmission shaft through the torsion spring; The end of the first transmission shaft is provided with a rotary encoder for recording its angular displacement and angular velocity; the second transmission shaft is provided with a magnetorheological damper arranged on it through a flange coupling. The present invention utilizes the characteristic that the magnetorheological damper can output the continuously controllable damping force, and can realize the force-sensing simulation of any nonlinear change, thereby providing the safety and comfort of vehicle operation.

Description

technical field [0001] The invention belongs to the field of intelligent driving vehicles, and relates to a pedal force feeling simulation device based on magnetorheology. Background technique [0002] Today's automobiles are developing in the direction of intelligence and networking, and neither traditional mechanical accelerators and brake pedals, or wire-controlled accelerators and brake pedals have been fully integrated into intelligent and networked control systems. Among them, only the pedal force manipulation signal of the driver is transmitted to the control system, and the control effect of the vehicle cannot be transmitted to the driver through the pedal. The current accelerator or brake pedal only plays the role of one-way information transmission. With the development of technology and the continuous improvement of the control performance requirements of the vehicle, people hope to perceive the vehicle working condition information through the pedal to realize th...
