Control system and method for drive-by-wire steering wheel of self-driving automobile

Abstract

A drive-by-wire steering wheel control system of an automatic driving vehicle comprises a steering wheel assembly and a steering wheel controller arranged on the automatic driving vehicle, and the steering wheel assembly comprises a steering wheel, an accelerator brake pedal device and a gear rocker device; the steering wheel controller comprises a power module, a CAN receiving and transmitting module, a control module and a USB communication module, a set of complete manual intervention control system can be provided at the initial stage of vehicle research and development, when an automatic driving system breaks down, and when related manual debugging is needed, debugging under the high-speed condition can be met, the steering stroke of the steering wheel is long, and the steering efficiency is high. According to the method, the steering of the vehicle can be accurately controlled, manual control can be safely achieved, the requirement for temporary vehicle control can be met, plug-and-play is achieved, the purpose of safety control can be achieved during high-speed driving, and the safety of the automatic driving vehicle is further improved.

Description

technical field [0001] The invention belongs to the technical field of automobile intelligent control, and in particular relates to a steering wheel control system and method for an automatic driving automobile. Background technique [0002] At present, the intelligentization of automobiles has achieved a blowout development. In the automatic driving of L4 and above, the driving system can completely take over the driving duties, and even cancel the redundant manual control components such as the steering wheel to complete the real automatic driving. However, in some special cases, such as the early stage of vehicle research and development, when the automatic driving system fails, or when relevant manual debugging is required, a complete manual intervention control system is still required. Currently, external remote controls are often used to achieve this Human control, but the disadvantage of the remote control is that it cannot meet the high-speed debugging, and the stee...

Problems solved by technology

However, in some special cases, such as the early stage of vehicle research and development, when the automatic driving system fails, or when relevant manual debugging is required, a complete manual intervention control system is still required. Currently, external remote controls are often used to achieve this Human control, but the disadvantage of the remote control is that it cannot meet the high-speed debugging, and the steering handle of the remote control has a short stroke, which cannot meet the precise control of the vehicle steering, and it is extremely unsafe to use the remote control handle during high-speed debugging, so There is an urgent need for a control method similar to the steering wheel, which can not only meet the initial debugging requirements, but also realize human control in a relatively safe manner.
