Title:
STEERING FEEL SIMULATION BOOSTER, STEERING BOOSTER, STEERING SYSTEM, AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2023/141785
Kind Code:
A1
Abstract:
A steering feel simulation booster, a steering booster, a steering system, and a control method. The steering feel simulation booster comprises a housing (113), a first transmission mechanism (112), pistons (111) and an intermediate member, wherein the housing (113) comprises a first structure (1131) and a second structure (1132); a hydraulic cavity is enclosed by the first structure (1131), the second structure (1132) and the pistons (111); the first transmission mechanism (112) is accommodated in the housing (113), and can convert a rotational motion into a linear motion, or convert the linear motion into the rotational motion; the intermediate member is connected to the first transmission mechanism (112) and drives, under the action of the first transmission mechanism (112), the pistons (111) to move to change the hydraulic pressure in the hydraulic cavity, so as to provide steering boosting for steering wheels (141, 142); alternatively, the intermediate member drives, under the action of the pistons (111), the first transmission mechanism (112) to rotate in the housing (113), so as to achieve road feel simulation during steering.
