The invention relates to an electric control hydraulic type vehicle steering system and method thereof. The system comprises a mechanical hydraulic power-assisted steering system, an electric controlhydraulic active steering system and a controller. The mechanical hydraulic power-assisted steering system can assist in a mechanical connecting rod to realize active steering of a front-end steeringaxle of the vehicle; the electric control hydraulic active steering system can drive a rear-end steering axle of the vehicle to steer. The controller in signal connection with an angular displacementsensor of the front-end steering axle can calculate angular displacement needed by the rear-end steering axle according to the angular displacement of the front-end steering axle and controls the electric control hydraulic active steering system to move so as to drive the rear-end steering axle to rotate by a set angle.
Description
technical field [0001] The invention belongs to the technical field of vehicles, and in particular relates to an electronically controlled hydraulic vehicle steering system and a debugging method. Background technique [0002] At present, the steering system of multi-axis vehicles mainly adopts mechanical linkage hydraulic power steering system, which has the advantages of low cost, safety and reliability, but the mechanical multi-axis steering has poor stability and flexibility under different working conditions when the vehicle is running at high speed. , it is difficult to take into account good passability at low speeds and driving stability at high speeds. [0003] The vehicle industry has new and higher requirements for the vehicle's narrow space passability and high-speed driving stability. The traditional mechanical linkage multi-axis steering system cannot take care of both. Electronically controlled hydraulic active steering is the current development direction of ...
