Abstract

The invention discloses a push rod type composite steering system and a mode switching control method thereof. The push rod type composite steering system comprises an electric power-assisted steering system and an electrically-controlled hydraulic power-assisted steering system. An assist motor A and an assist motor B are adopted, a corresponding assist mode switching control method is provided, the composite steering system can be switched to be in an electric power-assisted steering mode, an electrically-controlled hydraulic power-assisted steering mode and a hybrid power steering mode according to different working conditions, and steering assisting is achieved.

Description

technical field [0001] The invention belongs to the technical field of power steering systems, and in particular refers to a pushrod type compound steering system capable of switching working modes according to different working conditions and ensuring a good road feel of power steering and a mode switching control method thereof. Background technique [0002] At present, the power steering systems commonly used in existing automobiles include: hydraulic power steering systems, electronically controlled hydraulic power steering systems and electric power steering systems. Among them, the hydraulic power steering system and the electronically controlled hydraulic power steering system can provide greater power assistance under low-speed vehicle conditions and reduce the burden on the driver when steering; however, there are problems with steering feel and handling stability under high-speed conditions. The electric power steering system is composed of a controller, a booster ...
