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

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 drive unit is connected to one end of the crank. 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. Both the first elastic part and the second elastic part are arranged in the casing, and the two ends of the first elastic part respectively abut against the casing and the slider, and one end of the second elastic part is positioned on the casing, when the pedal is not triggered, The other end of the second elastic member is spaced apart from the slider, and the second elastic member is compressed after the slider moves to set a stroke. The pedal feeling simulator of the embodiment of the present invention can improve the response speed and mechanical performance of the vehicle braking system.
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 the car, the car usually adopts the brake by wire. The 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. The vehicle provides flexible and variable braking force. 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 factors such as pedal braking fee...
