Pedal simulator and brake-by-wire system with same, and vehicle

Abstract

The invention discloses a pedal simulator, a brake-by-wire system with the same, and a vehicle. The pedal simulator comprises a push rod, a plurality of elastic parts and an electromagnetic power-assisting part, wherein one end of each elastic part can be abutted, a pressure-bearing part is arranged at the other end of each elastic part, the multiple elastic parts are sequentially distributed in the axial direction of the push rod, the elastic part closest to the push rod abuts against the push rod through the corresponding pressure-bearing part, and when the push rod is located at the liftingposition, the multiple pressure-bearing parts are spaced with one another in the axial direction; and the electromagnetic power-assisting part is constructed to at least assist the elastic parts which are in abutting fit with the push rod in pushing against the push rod or acting on the elastic parts in abutting fit with the push rod in the direction away from the push rod when the electromagnetic power-assisting part is electrified. According to the pedal simulator, through compensation or retardation of the electromagnetic power-assisting part to force borne by the push rod, the pedal feeling provided for a driver is adjusted, the pedal braking feeling fed back to the driver is improved, the comfort of man-machine interaction is improved, and the driving experience of a driver is improved.

Description

technical field [0001] The invention relates to the field of vehicle manufacturing, in particular to a pedal simulator, a brake-by-wire system and a vehicle with the pedal simulator. Background technique [0002] In the related art, when the vehicle needs to be braked, the driver needs to depress the brake pedal. For traditional vehicles, the hydraulic or mechanical connection between the brake pedal and the brake of the traditional vehicle, the braking reaction force fed back by the braking system can directly act on the pedal to provide the driver with a comfortable and reasonable braking feeling. However, due to the addition of electric braking on electric vehicles and the cancellation of the hydraulic or mechanical connection between the brake pedal and the brake, the driver cannot directly perceive the reaction force fed back to the brake pedal when braking, resulting in the driver's braking. It feels bad and affects the driving experience of the driver. Contents of ...
