[0006] 2. Although some vehicles are equipped with cruise control and active adjustable speed limit functions at the same time, the cruise control and active adjustable speed limit functions work independently of each other, and many shared functions are not integrated together, resulting in complex functional structures and high costs. Moreover, it is not flexible to switch between the two functions of cruise control and active adjustable speed limit;

Example Embodiment

[0013] The present invention establishes a new system architecture to integrate the cruise and active adjustable speed limit functions into a new functional system, and integrates part of the cruise and active adjustable speed limit functions that have similar functions and can be borrowed from each other. Become a unified shared module, simplify functions, and improve the efficiency of ECU resources. At the same time, judge whether the cruise or active adjustable speed limit function can work normally according to the state signals and fault signals of the engine and the vehicle. If it does not work properly, cut off the torque response of the cruise or active adjustable speed limit function to improve the reliability of vehicle operation Sex. A new vehicle safety measure is added to prevent the vehicle from uncontrolled acceleration when the cruise function fails, and to ensure the controllability and safety of the vehicle. Because the driver’s arm is the part with the faste...

Abstract

The invention discloses a cruising and active adjustable speed limiting system of a vehicle, comprising a cruising-active adjustable speed limiting scheduling function layer, a cruising function layer, a speed limiting function layer and a virtual pedal calculating layer. The cruising function layer receives a cruising switch signal flow and cruising fault detecting signals from the cruising-active adjustable speed limiting scheduling function layer, if the condition of the vehicle is abnormal, a cruising function is interrupted, and if the cruising function is not interrupted, the target cruising torque of an engine is calculated and sent to the cruising-active adjustable speed limiting scheduling function layer; a speed limiting control layer receives a speed limiting switch signal flow and vehicle speed limiting signals from the cruising-active adjustable speed limiting scheduling function layer, if the condition of the vehicle is abnormal, an active adjustable speed limiting function is interrupted, otherwise speed limiting demand torque is outputted to the cruising-active adjustable speed limiting scheduling function layer; and the virtual pedal calculating layer calculates virtual pedal openings according to the actual torque and the speed of the vehicle. By using the invention, the out-of-control acceleration of the vehicle when in cruising error is prevented.

Description

technical field [0001] The invention relates to a vehicle engine control system. Background technique [0002] The cruise function on the vehicle allows the driver to adjust the cruise control switch to make the vehicle run and stabilize at a fixed speed without stepping on the accelerator pedal, which can free the driver's feet from the accelerator pedal and improve driving comfort. The active adjustable speed limit function allows the driver to actively set the maximum speed limit of the vehicle by adjusting the speed limit control switch. After the active adjustable speed limit function is activated, the vehicle will not exceed the maximum speed limit set by the driver. If it exceeds, the vehicle will have an obvious sound and light warning signal to remind the driver to improve the safety of vehicle driving. [0003] At present, many domestic models have been equipped with cruising function, but there are no models equipped with active adjustable speed limit function; ...
