What is the cause of Roewe 550 fault code p0567?

Fault code p0567 is a fault of cruise control system.

A system for automatically driving a vehicle at a constant speed. Its main function is to lock the speed according to the driver's demand, and it can automatically maintain a fixed speed without stepping on the accelerator. Driving on the highway, drivers can effectively reduce physical fatigue, while driving at a constant speed can save fuel consumption.

Constant speed cruise function:

(1) When the cruise button is pressed, the car can maintain its speed. When you press the brake pedal, this function disappears immediately. In addition to the elimination function of the brake pedal, there are also the elimination functions of operating switches such as parking brake, clutch (M/T) and shift control lever (A/T).

(2)? Fine-tune the speed and increase it.

(3)? Speed fine adjustment.

(4)? Electronic fuel saving function.

(5)? Throttle acceleration function.

(6)? Speed limit setting function.

(7)? Brake fault alarm function.

(8) Low-speed automatic elimination function: When the vehicle speed is less than 40km/h, the stored vehicle speed disappears and this vehicle speed cannot be recovered.

(9) Brake pedal elimination function.

Extended data:

Cruise control system is a system that uses electronic control technology to make the car automatically follow the speed set by the driver (advanced adaptive cruise can automatically follow the speed change of the preceding car).

The internal control system of the vehicle can automatically adjust the engine torque output according to the road condition, slope and wind resistance of the vehicle, so as to achieve the purpose of accurately controlling the vehicle speed, and the driver does not need to step on the accelerator, effectively reducing the driver's physical fatigue.

"When the cruise system works, it is equivalent to the driver handing over the control of the throttle to the on-board control system, which involves the identification of automobile safety and related responsibilities. Therefore, when the automobile cruise control system enters the working mode, it usually sets the preconditions with certain safety redundancy function and the exit mechanism under dangerous working conditions; Only by meeting a series of pre-judgment conditions can the car enter the cruise mode and logically ensure safety. " Professor Li Liang said.

In Professor Li's view, a mature product, especially a system involving automobile safety, such as a speed control product, is generally considered to be comprehensive.

If this situation is really reported, there must be a logic behind it, that is, a certain driving mode or operation combination may be beyond the scope of normal detection, and further data analysis and investigation are needed to see if the problem can be reproduced; Otherwise, it is necessary to test and analyze the fault modes of the control system more strictly.
