Embodiment Construction

[0035] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0036] see Figure 1-2As shown, an intelligent steering system includes VCU (vehicle controller), EPS (steering controller), instrument, torque sensor, angle sensor, steering motor, surround view camera, battery, steering wheel, power battery, steering oil pump inverter and steering oil pump;

[0037] The VCU (vehicle controller) is connected to the instrument and the EPS (steering controller) through the CAN bus, and one end of the VCU (vehicle controller) is connected to a surround-view camera and a brake pedal, and the ...

Abstract

The invention discloses an intelligent steering system. The intelligent steering system includes a vehicle control unit (VCU), electrical power steering (EPS), a meter, a torque sensor, an angle sensor, a steering motor, a looking-around camera, a storage battery, a steering wheel, a power battery, a steering oil pump frequency changer and a steering oil pump. The intelligent steering system has the beneficial effects that a rated working rotate speed V<n> of the steering pump is dropped to an idling rotate speed V according to a certain speed reduction slope through the VCU, rotate speed command information of the steering pump is sent to the steering pump frequency changer through a CAN bus, then the rotate speed, sent by the VCU, of the steering pump is responded by the steering pump frequency changer, the steering pump is controlled to reduce the speed by the steering pump frequency changer, thus idling treatment of the steering pump is achieved, a steering pump idling mode is entered, and vehicle-mounted energy consumed by the steering pump is reduced. In order to prevent damage caused by sharp turn in the high speed process, only after the current vehicle speed is lower thana vehicle speed threshold value V<m>, the sharp turn can be conducted so as to ensure whole vehicle safety in turn.

Description

technical field [0001] The invention relates to a steering system, in particular to an intelligent steering system, and belongs to the technical field of application of intelligent steering systems. Background technique [0002] At present, electric power steering pumps are generally used for steering assist in new energy vehicles. During the driving process of the whole vehicle, the steering pump is always in working condition, which consumes vehicle energy and also brings noise. At the same time, during the driving process of the whole vehicle, due to some misoperations or inattention of the driver, the steering of the whole vehicle will deviate, which will easily cause accidents. Contents of the invention [0003] The purpose of the present invention is to solve the problem that electric power steering pumps are commonly used in steering on new energy vehicles to assist steering. During the driving process of the whole vehicle, the steering pump is always in the working...
