Embodiment Construction

[0057] In order to make the above objects, features and advantages of the present application more obvious and understandable, the embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0058] Based on the problems mentioned in the background technology, the inventor proposed various types of control strategies for the electronic tuning valve after research to adapt to different operating states of the vehicle, so as to realize the control of exhaust noise under different operating states of the vehicle. Eliminate and meet the needs of users.

[0059] Specifically, the vehicle engine controller ECM (Engine Control Module) can determine the current operating conditions of the vehicle according to vehicle parameters, such as power-on, power-off, driving, etc., and determine the corresponding control strategy according to the current operating conditions. Then, determine...

Abstract

The embodiment of the invention discloses an electronic tuning valve control method and device, and the method comprises the steps of obtaining a vehicle parameter by a controller, so as to determine the operation condition of a vehicle according to the vehicle parameter; and when the running condition is that the vehicle runs, acquiring a trigger signal generated by the user through the trigger operation so as to determine a control strategy corresponding to the current running condition according to the trigger signal; and when the control strategy is a motion strategy, reading the driving parameters of the vehicle, such as the rotating speed of the engine and the opening degree of the accelerator pedal, determining the opening degree of the electronic tuning valve corresponding to the current operation condition according to the read driving parameters, and controlling the electronic tuning valve to act. Visibly, through the control method provided by the embodiment of the invention, the controller can control the opening degree of the electronic tuning valve according to the real-time operation working condition of the vehicle, effectively treat exhaust noise under different working conditions, reduce noise pollution, improve riding comfort and driving comfort, and improve driving safety.

Description

technical field [0001] The present application relates to the technical field of automatic control, in particular to an electronic tuning valve control method and device. Background technique [0002] With the development of the domestic automobile industry, users have higher and higher requirements for the comfort and safety of vehicles. In the prior art, for the noise generated by the exhaust system, an acoustic mode of a single noise, vibration and harshness (Noise, Vibration, Harshness, NVH) state is mainly used to deal with the exhaust noise. That is, the existing processing method adopts a single control strategy to process exhaust noise, which cannot meet the needs of users. Contents of the invention [0003] In view of this, the embodiment of the present application provides an electronic tuning valve control method and device to achieve a more reasonable and effective treatment of exhaust noise under different working conditions, reduce noise pollution, and impro...
