Embodiment Construction

[0013] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0014] figure 1 is a schematic diagram of an acquisition device for engine downtime according to the present invention. Such as figure 1 As shown, the acquisition device of the engine shutdown time provided by the present invention may include: a detector 110, which detects the state of the ignition switch of the engine and the speed of the engine; and a controller 120, which detects that the ignition switch is switched to flameout state, restart accumulating the stop time of the engine until it is detected that the rotational speed of the engine is greater than a preset value. Wherein, the preset value may be 300 rpm, but the present invention is not limited...

Abstract

The invention discloses a device and method for acquiring engine downtime. The acquiring device comprises a detector and a controller. The detector is used for detecting the state of an ignition switch of an engine and the rotating speed of the engine. The controller is used for accumulating the downtime of the engine again when it is detected that the ignition switch is switched to be in the flameout state until it is detected that the rotating speed of the engine is larger than a preset value. Accordingly, the demand for acquiring the engine downtime is met, and the development cycle and cost are saved.

Description

technical field [0001] The present invention relates to the field of engines, in particular to a device and method for acquiring engine downtime. Background technique [0002] An engine is a power output device. Engine shutdown time refers to the time interval from the engine shutdown to the next successful ignition operation. In the electronic control device installed with the engine, it is usually necessary to receive the bus signal of the engine stop time. For example, in an automobile system equipped with a bus network, including multiple controller systems such as automatic air conditioning, four-wheel drive, and ESP electronic stability system, in order to realize its complex functions, it is necessary to obtain the bus signal of the engine downtime. [0003] If the power system adds the function of obtaining downtime, it will bring higher development cycle and cost. Contents of the invention [0004] The object of the present invention is to provide a device and ...
