Problems solved by technology

The vibration of the engine is transmitted to the seat guide rail through the powertrain mount, frame, cab mount, cab floor, etc. If the engine itself has a large excitation or the vibration isolation system of the vehicle is not properly matched, the seat will vibrate seriously and the comfort poor sex

Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0018] Such as figure 1 As shown, the present invention provides a control system for rapid engine flameout, which is used in the process of engine flameout, including a start-stop device 1 , a vehicle or engine control unit 2 , an actuator solenoid valve 3 and an actuator 4 .

[0019] The flameout signal is sent by the start-stop device 1 according to the operation needs of the user, and the signal transmission is carried out according to the J1939 protocol. The flameout signal is transmitted to the vehicle or engine control unit 2 through the wiring harness, but the vehicle or engine control unit 2 will not enter the power-off state immediately, and the execution command will be sent to the actuator solenoid valve 3 through the wiring harness through the interactive processing of the signal. or other electronic control components, after receiving the order...

Abstract

The invention discloses an engine rapid stalling control system. The engine rapid stalling control system is used for the engine stalling process and comprises a start-stop device (1), a complete vehicle or engine control unit (2), an actuator solenoid valve (3) and an actuator (4), wherein the start-stop device (1), the complete vehicle or engine control unit (2), the actuator solenoid valve (3)and the actuator (4) are sequentially connected through wire harnesses for electronic signal interaction; the start-stop device (1) sends a stalling signal according to user operation demands; the stalling signal is transmitted to the complete vehicle or engine control unit (2) through the wire harnesses, and after signal interactive processing, the engine stalling rate is increased through starting and stopping of the actuator (4), so that the rapid stalling purpose is achieved. By analyzing the engine stalling process, the rotation speed reduction rate of the engine stalling process is increased, the time of passing through the resonance point is shortened, and the stalling shaking phenomenon can be effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of manufacturing and control of heavy-duty vehicles and parts, and in particular relates to a control system for rapid engine flameout. Background technique [0002] With the continuous development of the automobile industry, the market competition is intensifying, and more and more new technologies, new structures, and new processes are applied to automobile products. The trade-off of comprehensive performance, among which comfort has evolved into an important indicator of automobile performance evaluation. [0003] NVH performance is the perfect interpretation of product comfort, and it defines the quality of an automotive product in terms of vibration and noise. In the past, most people focused on whether the NVH performance of the whole vehicle meets the requirements during operation, and it is easy to ignore the performance of the whole vehicle during startup or flameout, but the quality of the whole v...
