Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and implementation examples.

[0023] figure 1 It is a flowchart of an EPS-based automatic steering control method, and the specific process is as follows:

[0024] (1) Determine whether the automatic steering control device is activated; if activated, turn to (2), otherwise turn to (5);

[0025] (2) The control module receives the host computer command and turns to (3);

[0026] (3) The torque simulation module generates an output signal according to the control module command and sends it to the mode selection module, and turns to (4);

[0027] (4) mode selection module selects the output signal of torque simulation module to send electronic control unit, turn (8);

[0028] (5) The torque sensor of the electric power steering system generates an output signal according to manual operation, turn to (6);

[0029] (6) The output signal of the torque sensor of the elect...

Abstract

The invention particularly relates to an automatic steering control method and device for a vehicle provided with an electric power steering system. The automatic steering control device based on EPS comprises the electric power steering system and an automatic steering control unit, wherein the automatic steering control device is composed of an upper computer, a control module, a torque simulation module and a mode selection module. Under the control of the control module, manual steering or automatic steering is selected by the mode selection module, steering information is transmitted to an electronic control unit, a motor is driven to work, and control over vehicle steering is achieved. The automatic steering control device is low in cost, accurate in steering, high in reliability, small in size, convenient to install and capable of being started when needed, and does not affect use of original EPS.

Description

technical field [0001] The invention relates to the technical field of automobile steering control, in particular to an automatic steering control method and a control device for vehicles equipped with EPS. Background technique [0002] With the advancement of modern technology and the development of science and technology, there are higher requirements for modern vehicles. On the basis of satisfying traditional driving, intelligent control of vehicles is realized, such as driverless cars, adaptive cruise, vehicle active safety, fully automatic functions such as parking. As an important part of intelligent control, vehicle automatic steering control can intelligently change the driving direction of the car. [0003] At present, the electric power steering (EPS) system has occupied an important position in the steering assist system of passenger cars, gradually replacing the mechanical hydraulic power steering system. When the driver manipulates the steering wheel to turn, ...
