Problems solved by technology

But also because of this, the brake-by-wire system cannot provide the driver with a brake pedal feel through the brake hydraulic circuit, which is not conducive to the driver's handling of the vehicle, so a pedal feel simulator is required to provide a feedback force to ensure the driver's foot feel
However, the current pedal feel simulator can simulate a single pedal feel, lack of variation, cannot selectively choose the appropriate pedal feel, and cannot well match drivers with different driving habits

Abstract

The invention relates to a pedal feeling simulator with variable pedal feeling, comprising a simulation cylinder, a first piston, a second piston, a third piston, a fourth piston, a fifth piston, a first spring, a second spring and a third spring , pedal cylinder, first solenoid valve, second solenoid valve, third solenoid valve, electric control unit ECU and pedal displacement sensor; the pedal feeling simulator with variable pedal feeling of the present invention includes three kinds of pedal feeling modes, and the structure It is simple and can provide good pedal feeling. The spring is mainly used as the component to generate the pedal feedback force. Different spring combinations are used to simulate the pedal feeling in different braking stages, and the on-off of the hydraulic circuit can be controlled by the opening and closing of the solenoid valve. Different combinations of springs in the working state achieve different pedal sensations, and drivers can choose different pedal sensation modes according to their own driving habits to achieve a better driving experience.

Description

technical field [0001] The invention relates to a pedal feeling simulator, in particular to a multi-mode pedal feeling simulator with variable pedal feel. Background technique [0002] With the development of automobile electrification and intelligence, more and more automobiles use brake-by-wire systems to replace traditional brake systems using vacuum boosters. In the brake-by-wire system, the electronic control unit ECU receives the signal of the pedal travel sensor, and controls the rotation of the brake motor according to the signal, and pushes the piston to generate brake pressure. The brake-by-wire system is not only simple in structure, but also has faster response speed and better controllability than the traditional brake system, which is the advanced development direction of the brake system. [0003] The brake pedal of the brake-by-wire system is decoupled from the brake hydraulic circuit, which can conveniently realize the regenerative braking function. But al...
