Abstract

A braking pedal feel simulating device of an automobile brake-by-wire system comprises a braking pedal, a pedal controlling arm, a pedal shaft, a pedal fixing support, a torsion spring, a pedal angle displacement sensor, a pedal force sensor and a pedal feel simulator. The braking pedal is fixedly connected with the pedal controlling arm, a round hole is processed at the upper end of the pedal controlling arm which is rotatably connected with the pedal shaft, the pedal shaft is mounted in a mounting hole of the pedal fixing support, a guide small hole is formed in the pedal fixing support, the diameter of the guide small hole is in interference fit with the outer diameter of a pushing rod, the torsion spring is cylindrical and is sleeved on the pedal shaft in a hollow manner, one end of the torsion spring is fixedly connected on the pedal fixing support while the other end of the same is connected on the pedal controlling arm, the torsion spring reverses and generates spring force along with rotating of the pedal controlling arm, the pedal angle displacement sensor is mounted in the round hole at the upper end of the pedal controlling arm, the pedal force sensor is mounted on the braking pedal, and the front end of a pushing rod of the pedal feed simulator is rotatably connected with the pedal controlling arm.

Description

technical field [0001] The invention relates to a brake pedal simulation device of an automobile braking system, in particular to a brake pedal feeling simulation device of an automobile brake system by wire, and belongs to the technical field of automobile manufacturing. Background technique [0002] The control-by-wire technology is developed with the development of electronic technology and network technology. The electric vehicle brake-by-wire system is formed by combining the control-by-wire technology with the composite braking system of electric vehicles. The wire is the information transmission medium, and the electric drive element is used as the actuator. The control unit recognizes the driver's braking intention according to the pedal action information, distributes the braking force, and then controls the actuator to realize the braking of the electric vehicle. Pedal action information can be pedal displacement, speed or pedal force, etc. [0003] In the brake-b...
