Solution Overview

Problem

Shared vehicles experience continuous power consumption due to always-on wireless communication and GPS components, leading to increased energy usage and reduced battery life.

Innovation Solution

A method and apparatus that determine the state of a vehicle using driving data from sensors, adjusting the power consumption mode of the energy consumption circuit accordingly, switching between energy-saving and full power modes based on the vehicle's state, such as stopped, started, or riding, to optimize energy use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If wireless communication component and GPS component are kept in operating state to transmit state information in real time, then the state information transmission is ensured, but continuous power consumption increases

Engineering Contradiction:
Improvestate information transmissionVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic action by switching the wireless communication component and GPS component between operating state and sleep state based on vehicle state. During riding state, the vehicle transmits state information periodically or when state changes occur, rather than continuously. When the vehicle is stopped or in idle state, these components switch to sleep state to reduce power consumption, thus resolving the contradiction between reliable state information transmission and continuous power consumption.

Inventive Principle:
Principle #19Periodic action

2Reliability

If energy consumption circuit operates in full power mode to ensure real-time state transmission, then the transmission reliability is improved, but battery service life is reduced

Engineering Contradiction:
Improvetransmission reliabilityVSAvoidbattery service life
Core Design Contradiction:
ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The patent applies dynamics by making the power consumption mode of the energy consumption circuit adjustable and state-dependent. The controller dynamically switches between full power mode and energy-saving mode based on the vehicle's state information. When the vehicle is in riding state, full power mode ensures reliable transmission; when stopped or idle, energy-saving mode extends battery service life. This dynamic adaptation resolves the contradiction between transmission reliability and battery service life.

Inventive Principle:
Principle #15Dynamics
