Embodiment 1

[0053] Please refer to Figure 3-4 , Embodiment 1 of the present invention is: a vehicle energy-saving control method, this method is based on curve prediction, and can be applied to vehicle control systems, such as image 3 shown, including the following steps:

[0054] S1: Obtain the load threshold corresponding to each gear position of the multi-power switch in the default state.

[0055]By default, the existing multi-power switch is divided into gears according to the load value of the flat road. Assuming that the multi-power switch has N gears in total, the load threshold is N-1, respectively P 1 , P 2 , P 3 ,...,P N-1 .

[0056] S2: When the vehicle is started, the actual load value is obtained through the load sensor, that is, the current load value is obtained.

[0057] S3: Determine the corresponding gear according to the actual load value and the load threshold, and switch the multi-power switch to the corresponding gear.

[0058] Specifically, the power conve...

Embodiment 2

[0078] This embodiment is a computer-readable storage medium corresponding to the above-mentioned embodiments, on which a computer program is stored, and when the program is executed by a processor, the following steps are implemented:

[0079] Obtain the load threshold corresponding to each gear of the multi-power switch;

[0080] When the vehicle starts, the actual load value is obtained through the load sensor;

[0081] Determine the corresponding gear according to the actual load value and the load threshold, and switch the multi-power switch to the corresponding gear;

[0082] When the vehicle is running, the road information in front of the vehicle is obtained, and the road information includes the curvature radius of the curve in front of the vehicle;

[0083] Calculate the equivalent mass according to the radius of curvature, the total mass of the vehicle, the vehicle speed and the preset road friction coefficient;

[0084] Determine the predicted gear position accor...

Abstract

The invention discloses a vehicle energy-saving control method, a storage medium, a vehicle control system and a vehicle. The method comprises the steps that load thresholds corresponding to all gears of a multi-power switch are acquired; when the vehicle is started, an actual load value is obtained through a load sensor; a corresponding gear is determined according to the actual load value and the load thresholds, and the multi-power switch is turned to the corresponding gear; when the vehicle runs, road information of a curve in front of the vehicle is acquired, wherein the road information comprises a curvature radius in front of the vehicle; equivalent mass is calculated according to the curvature radius, the total mass of the vehicle, the vehicle speed and a preset road friction coefficient; a predicted gear is determined according to the sum of the actual load value and the equivalent mass; and if the predicted gear is different from the current gear, the multi-power switch is turned to the predicted gear. Through the method, the problem of energy waste caused by mismatching of power output when the vehicle passes through the curve can be solved.

Description

technical field [0001] The invention relates to the technical field of vehicle control, in particular to a vehicle energy-saving control method, a storage medium, a vehicle control system and a vehicle. Background technique [0002] The variable range of commercial vehicle load is very large, and the difference between full load and no load state can reach tens of tons. Therefore, most commercial vehicle engines adopt the method of multi-speed power / torque and load matching for energy-saving control. For example, the Chinese published patent with the publication number CN201301754Y discloses a switch that can manually switch engine power; the Chinese authorized patent with the publication number CN101392691B discloses a method for using vehicle loads to match light and heavy load power grades; the Chinese patent with the publication number CN105332805A The published patent further discloses the method of using the load sensor to automatically match the corresponding power l...
