Embodiment Construction
[0038] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0039] Due to the low charging efficiency of natural gas engines and the distance from the throttle valve on the intake pipe to the engine cylinder, there is a certain delay from the set intake air volume to the actual intake air volume into the cylinder, which affects the engine. Especially when the vehicle starts, there is a certain time delay f...

The embodiment of the invention provides a vehicle starting control method, device and equipment and a storage medium. According to the method, for a natural gas engine vehicle, when an engine is currently in an idling working condition before starting, whether the vehicle enters into a starting state is judged according to whether vehicle state information is changed, wherein the vehicle state information includes a gear state signal and / or a clutch state signal; and if the vehicle is determined to enter into the starting state, an engine is controlled according to vehicle configuration information to increase an output torque of the engine when the vehicle starts. According to the embodiment of the invention, vehicle starting can be quickly determined through a vehicle state informationchange; meanwhile, a characteristic that a natural gas engine is slow in response is comprehensively considered, the engine is controlled to increase the output torque of the engine when the vehicle is started, instant increase of an engine load caused by vehicle starting is rapidly responded, and a problem of rotating speed undershoot or flameout when the vehicle is started is solved to a certainextent.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of engines, and in particular, to a method, device, device and storage medium for controlling vehicle starting. Background technique [0002] In recent years, natural gas engines have been more and more widely used because they use clean energy and have social, environmental and economic benefits. [0003] The gas charging efficiency of the existing natural gas engine is low and there is a certain distance from the throttle valve on the intake pipe to the engine cylinder, so there is a certain delay from the set intake air volume to the actual intake air volume entering the cylinder, thus affecting The transient response of the engine is improved; when a vehicle using a natural gas engine is started, there is a certain time delay from when the vehicle has a speed to when the engine control unit recognizes the speed signal, so the engine control unit uses the recognized speed signal ...
