Problems solved by technology

In the brake-by-wire system, due to the cancellation of the hydraulic or mechanical connection between the brake pedal and the brake, the driver cannot directly perceive the brake reaction force fed back to the brake pedal when braking, thus losing the traditional brake system. The braking feeling caused by the pedal is not good

Abstract

The invention discloses a pedal feeling simulator of a vehicle and a vehicle having the same. The vehicle includes pedals, and the pedal feel simulator includes a shell, a crank-slider mechanism, a driving part, a moving push rod, a first elastic part and a second elastic part. The slider crank mechanism includes a crank, a connecting rod and a slider. The two ends of the connecting rod are respectively connected with the crank and the slider, and the slider is reciprocally movable and arranged in the casing. The driving part is connected with one end of the crank to drive the crank to rotate. One end of the moving push rod cooperates with the slide block to drive the slide block to move, and the other end of the moving push rod is suitable for being connected with the pedal. The first elastic part and the second elastic part are arranged in the casing, the first end of the first elastic part is positioned in the casing, the second end of the first elastic part is matched with the slider, and the two ends of the second elastic part are respectively connected with the slider Cooperate with moving push rod. According to the pedal feel simulator of the present invention, the response speed and mechanical performance of the vehicle braking system are improved by using a purely mechanical mechanism to simulate the pedal feel during driving.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular, to a pedal feel simulator of a vehicle and a vehicle having the same. Background technique [0002] In order to improve the effective braking of automobiles, some automobiles in the related art adopt brake-by-wire. Brake-by-wire not only has the characteristics of fast response, high control precision, good braking performance, and flexible layout, but also can be integrated with the vehicle dynamic control system. Integrate to provide flexible and variable braking force for the vehicle. In the brake-by-wire system, due to the cancellation of the hydraulic or mechanical connection between the brake pedal and the brake, the driver cannot directly perceive the brake reaction force fed back to the brake pedal when braking, thus losing the traditional brake system. The braking feeling caused by the pedal is not good. Braking feeling is a comprehensive feeling, which includes many fa...
