Abstract

The invention discloses a method for estimating the optimal driving speed of a vehicle, which relates to the technical field of vehicle driving speed recommendation, and comprises the following steps: e and torque T e Estimate the instantaneous fuel consumption FC; obtain the driver's feeling parameter S based on the vehicle speed at the front and rear moments during the driving process; establish the objective function J=Q1×FC+Q2×T+Q3× according to the instantaneous fuel consumption FC, driving time T and driver's feeling parameter S S, where Q1, Q2 and Q3 respectively represent the reference coefficients of instantaneous fuel consumption FC, travel time T and driver's feeling parameter S; based on the above-mentioned objective function J, the optimal travel speed Vo is obtained, and the optimal travel speed Vo is output ; Considering the vehicle's instantaneous fuel consumption FC, driving time T and driver's feeling parameter S comprehensively, the driver's optimal driving speed can be estimated based on less fuel consumption, and the driver's driving experience is also taken into account.

Description

technical field

[0001] The invention relates to the technical field of automobile driving speed recommendation, more specifically, it relates to a method for estimating the optimal speed of automobile driving. Background technique

[0002] With the rapid development of society, cars have increasingly become an indispensable means of transportation for people to travel. Car enthusiasts are more concerned about the fuel consumption of their cars, especially as the oil price of cars is rising steadily, and the cost of fuel products for cars has increasingly become a part that car owners have to pay attention to. Among them, the speed of the car during driving is closely related to the fuel consumption. The survey found that the higher the speed of the car engine, the greater the power and utilization rate, and the smaller the unit fuel consumption; but when the car speed is too high and exceeds the minimum fuel consumption speed of the engine, the fuel consumption increases wi...
