Embodiment Construction

[0037] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.

[0038] A computing system for power consumption per unit time of a pure electric vehicle, including a vehicle ECU, a vehicle CAN bus, a battery management system and a liquid crystal display;

[0039] Vehicle CAN bus, used to transmit the vehicle speed to the vehicle ECU;

[0040] The battery management system is used to transmit the power consumption ΔQ of the vehicle driving Δt time to the on-board ECU;

[0041] The on-board ECU is used to divide the vehicle speed range into multiple speed gradients, and calculate and store the cumulative vehicle power consumption and power consumption time under different speed gradients; receive the vehicle speed transmitted by the vehicle CAN bus, and judge the The driving speed gradient to which the vehicle driving speed belongs, obtains the power cons...

Abstract

The present invention provides a system and method for calculating the power consumption per unit time, the vehicle cruising range and the power required for the driving journey of a pure electric vehicle. The vehicle driving speed range is divided into a plurality of driving speed gradients. The calculation is the power consumption per unit time under different driving speed gradients, so the different driving habits of drivers lead to different update times of the power consumption per unit time under different driving speed gradients, that is, the driving speed gradient of the driver is accustomed to driving. The power consumption per unit time is updated more times, and the power consumption per unit time under the driving speed gradient is more accurate, so the vehicle cruising range can be calculated more accurately, and the vehicle consumption from the origin to the destination can be more accurately estimated. power.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to a system and method for calculating power consumption per unit time, cruising range of a vehicle, and power required for a driving journey of a pure electric vehicle. Background technique [0002] With global warming and climate deterioration, air pollution has become increasingly serious, and countries have made substantial adjustments to their industrial structures. Especially in the field of automobiles, the disadvantages of insufficient combustion of traditional fuel vehicles and serious air pollution have been paid attention to. For example, on urban roads, the start and stop of vehicles during peak traffic periods, as well as the rapid acceleration and deceleration of vehicles, will cause serious air pollution. Therefore, in recent years, the transition from traditional fuel vehicles to new energy vehicles has been designated as an important national strategic plan. [...
