Embodiment Construction

[0027] Below in conjunction with accompanying drawing, structural principle and working principle of the present invention are specifically described:

[0028] Please refer to figure 1 and figure 2 , which are schematic flow charts (1) and (2) of the method for preventing engine flameout in the non-idling flameout mode according to the first embodiment of the present invention, which specifically disclose the non-idling flameout mode in the first embodiment of the present invention A method for preventing engine flameout, the method is applicable to a vehicle having a belt-driven starter generator (BSG) and an engine, and the belt-driven starter generator is connected to the engine for power. The vehicle may be, for example, a gasoline-electric hybrid vehicle, but the present invention is not limited thereto. The belt motor generator has a generator mode and a motor mode. In the power generation mode, the belt motor generator is driven by the engine power to generate elect...

Abstract

An engine stall preventive method is applicable to a vehicle comprising a belt motor generator and an engine; the belt motor generator is in dynamic connection with the engine; the belt motor generator has a power generating mode where the generator is driven by power of the engine to generate electricity and a motor mode where the generator drives the engine to run. The method includes: during running of the engine, determining that the engine is in a non-idle stall mode; if the speed of the engine is less than a low threshold, allowing the engine to enter in a staff preventive mode including switching the belt motor generator to the motor mode; increasing a torque output value of the belt motor generator till the speed of the engine being greater than a high threshold.

Description

technical field [0001] The invention relates to a method for preventing engine flameout in a non-idling flameout mode, in particular to a method for preventing engine flameout in a non-idling flameout mode using a belt-type motor generator. Background technique [0002] In order to meet the requirements of energy saving and carbon reduction, vehicles equipped with idling stop system have a mechanism to stop the engine when idling (for example: waiting for traffic lights, traffic jams, roadside pauses, etc. to stop the vehicle for more than three minutes), and wait for the need Restart the engine while driving the vehicle, thereby reducing fuel consumption and avoiding excessive exhaust emissions. Still, for every driver, having the engine stall when it's not idling is something that's not at all desirable. [0003] The flameout of the engine in the non-idling state may occur when the load on the vehicle engine increases and the engine speed is insufficient, such as when dri...
