The invention discloses a pedal simulator and its brake-by-wire system and vehicle. The pedal simulator includes: a push rod; a plurality of elastic parts, one end of each elastic part can be stopped and the other end is set There is a pressure-bearing part, and multiple elastic parts are distributed sequentially along the axial direction of the push rod. The elastic part closest to the push rod is always in contact with the push rod through the pressure-bearing part. When the push rod is in the raised position, the multiple pressure-bearing parts Upwards are spaced apart from each other; the electromagnetic assisting part, the electromagnetic assisting part is configured to at least assist the elastic member that is in contact with the push rod to push against the push rod or act on the elastic member that is in contact with the push rod in a direction away from the push rod when energized. pieces. According to the pedal simulator of the present invention, the pedal feeling provided to the driver is adjusted through the electromagnetic power-assisted component to compensate or block the force received by the push rod, thereby improving the pedal braking feeling fed back to the driver, and improving the The comfort of human-computer interaction improves the driver's driving experience.
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 driver's driving experience. Contents of the i...
