Document Type and Number:
WIPO Patent Application WO/2022/000444
Kind Code:
A1
Abstract:
A pedal feel adjustment device comprises: a pedal assembly, a main cylinder assembly, a first flow adjustment assembly (107), an electronic control unit (ECU) (109), and a liquid storage container (108). The main cylinder assembly comprises a main cylinder body. A first piston (103) is provided in the main cylinder body. The main cylinder body is divided into a first chamber (105) and a second chamber (104) by the first piston (103). The first chamber (105) and the second chamber (104) do not communicate with each other. The first piston (103) is connected to one end of a push rod (102) of the main cylinder assembly, and the other end of the push rod (102) passes through the second chamber (104) and is connected to the pedal assembly. A first liquid port of the first chamber (105) is connected to one end of the first flow adjustment assembly (107), and the other end of the first flow adjustment assembly (107) is connected to a liquid outlet of the liquid storage container (108). The ECU (109) is electrically connected to the first flow adjustment assembly (107), and controls the degree of opening of the first flow adjustment assembly (107). By means of the device, pedal feel is adjusted, thereby improving driving experience.
