Problems solved by technology

However, this technology can only solve the fuel consumption problem in the idle state of the engine, and has no effect on the fuel consumption of the vehicle during coasting. The oil function will resume fuel injection when the engine speed drops to 1400 rpm, and the vehicle is still in the process of coasting. This continuous fuel injection will cause the engine to increase fuel consumption and waste fuel, which is not conducive to environmental protection

Embodiment Construction

[0071] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0072] Please refer to Figure 1-Figure 3 , in a specific embodiment, the vehicle fuel saving control method provided by the present invention includes

[0073] Step S1: Detect whether the vehicle is in the state of deceleration and fuel cut-off;

[0074] Step S2: If the vehicle is in the state of decelerating and cutting off fuel, check whether the engine speed is lower than the first preset value;

[0075] Step S3: If the engine speed is lower than the first preset value, the vehicle is in a safe and fuel-saving state;

[0076] Step S4: Detect whether the vehicle meets the safety stop conditio...

Abstract

The invention belongs to the technical field of vehicle parts, and provides a vehicle oil saving control method; the judgment of safety machine stop conditions, air conditioner glide safety conditions and safety starting conditions is added; traditional deceleration oil cutoff function and starting / stopping function are used; and the further oil saving control is performed after an original vehicle deceleration oil cutoff state when an engine is going to be started. The vehicle oil saving control method uses the traditional deceleration oil cutoff function and automatic starting / stopping function, and adds the detection of the engine deceleration oil cutoff state and the detection of the engine rotating speed; when the vehicle is in the deceleration oil cutoff state, even if the rotating speed of an engine is lowered below 1400 r / m, the engine can be kept in a stop state without externally acting, so that the oil is continuously saved, the oil utilization rate is improved, and the environment is protected; and meanwhile, after the engine is in the stop state, since whether neutral glide safety conditions are satisfied is detected, the vehicle oil saving purpose can be achieved, and the driving safety can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of automobile parts, and in particular relates to a vehicle fuel-saving control method. Background technique [0002] The GB27999 Passenger Car Fuel Consumption Four-Stage Standard stipulates that by 2020 the overall fuel consumption standard for passenger cars will be 5L / 100km. For this reason, various automobile manufacturers are studying fuel-saving control methods such as pure electric drive and hybrid power. [0003] Existing vehicle fuel-saving control methods mainly use engine idling start-stop technology to solve unnecessary fuel consumption under the condition of vehicle parking and idling, thereby achieving the purpose of fuel saving. However, this technology can only solve the fuel consumption problem in the idle state of the engine, and has no effect on the fuel consumption of the vehicle during coasting. The oil function will resume fuel injection when the engine speed drops to 1400 rpm, and t...
