Vehicle energy saving control method, storage medium, vehicle control system, and vehicle

A vehicle energy saving control method, comprising:

• obtaining a load threshold corresponding to each gear position of a multi-power switch;
• obtaining an actual load value by a load sensor when a vehicle starts;
• determining a corresponding gear position according to the actual load value and the load threshold, and switching the multi-power switch to the corresponding gear position;
• obtaining road information ahead of the vehicle when the vehicle is driving, wherein the road information comprises a curvature radius of a corner ahead of the vehicle;
• calculating equivalent mass according to the curvature radius, total mass of the vehicle, a speed of the vehicle and a preset road friction coefficient;
• determining a predicted gear position according to a sum of the actual load value and the equivalent mass;
• and
• switching the multi-power switch to the predicted gear position when-if the predicted gear position is different from a current gear position;
• wherein the step of calculating equivalent mass according to the curvature radius, total mass of the vehicle, a speed of the vehicle and a preset road friction coefficient comprises:
• calculating the equivalent mass according to a first formula, wherein the first formula is Δm=(mv2)/(gμr), Δm is the equivalent mass, m is the total mass of the vehicle, v is the speed of the vehicle, g is a gravity angular velocity, p is the preset road friction coefficient, and r is the curvature radius of the corner ahead of the vehicle.
