Vehicle Engine Start-Stop Prioritization for Driver and Safety Commands
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current start-stop technologies in vehicles result in prolonged engine start-stop times, increased fuel consumption, and compromised safety due to inadequate prioritization of start-stop instructions, leading to inefficient engine control and potential safety hazards.
Innovation Solution
A method and device that acquire and prioritize start-stop instructions through a processor and vehicle controller, determining the appropriate start-stop type to actively control engine operations, thereby improving driving experience, reducing fuel consumption, and ensuring safety by selecting the start-stop type with higher priority based on real-time conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the engine completes the stop according to the stop instruction before starting again, then the engine stop function is fulfilled, but the start-stop time is prolonged and fuel consumption increases
Solution Approach 1:
The control device determines the start-stop type before executing the start-stop instruction. By preliminarily identifying whether it is a first start-stop type (driver intention) or second start-stop type (safety requirement), the system can prepare the appropriate response strategy in advance, avoiding prolonged stop completion processes and reducing overall start-stop time
2Reliability
If the engine completes the start according to the start instruction after receiving it, then the engine start function is fulfilled, but safety is compromised when collision or abnormality occurs during starting
Solution Approach 1:
The control device preliminarily determines the start-stop type by checking whether a second start-stop instruction (safety requirement) exists before executing the start instruction. This preliminary assessment allows the system to prevent engine starting when safety hazards are detected, avoiding the harmful effect of starting during collision or abnormality
Solution Approach 2:
The control device acts as an intermediary between the start instruction and engine execution. It introduces a determination step that mediates whether the start instruction should be executed, blocking the start process when safety hazards are present while allowing normal starts to proceed
3Adaptability or versatility
If the engine responds to all start-stop instructions equally without prioritization, then all instructions are processed, but driving experience is degraded and fuel consumption increases
Solution Approach 1:
The control device segments start-stop instructions into two distinct types: first start-stop type (driver intention) and second start-stop type (safety requirement). This segmentation allows the system to process different instructions according to their specific characteristics and priorities, improving both adaptability and driving experience
Solution Approach 2:
The control device changes the processing parameter by determining the start-stop type before execution. This parameter change (from uniform processing to type-based processing) enables the system to prioritize safety requirements while still responding to driver intentions, thereby improving driving experience and reducing fuel consumption

AI summary
The present application disclosed a a method and a device for controlling start-stop of a vehicle, a vehicle and an electronic apparatus. The method includes steps of: acquiring a first start-stop instruction, and determining a first start-stop type of the vehicle according to the first start-stop instruction; acquiring a second start-stop instruction, and determining a second start-stop type of the vehicle according to the second start-stop instruction; and performing start-stop controlling on an engine according to priorities of the first start-stop type and the second start-stop type. Therefore, the method can actively control the start-stop of the engine according to the priority of the start-stop type, which can well respond to the driving intention of the driver, the driving experience is improved, the start-stop time of the engine is saved, and the fuel consumption of the vehicle is greatly reduced, and the driving safety of the vehicle and the personal safety of the driver and passengers are guaranteed.
