Vehicle Engine Start-Stop Priority Control for Driver-Intent Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle start-stop systems require long start-stop times, leading to poor driving experience, increased fuel consumption, and compromised safety due to unsynchronized engine control with driver intent and vehicle conditions.
Innovation Solution
A method and device that actively control engine start-stop based on priority settings, responding to driver intent and vehicle conditions to optimize fuel consumption and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the engine completes the stop according to the stop instruction, then the engine stop function is achieved, but the start-stop time is long and fuel consumption increases
Solution Approach 1:
The control unit determines whether to prohibit engine start in advance based on the reception timing of start prohibition information before the engine start instruction is executed. This preliminary determination allows the system to prepare for potential start prohibition scenarios, enabling faster response when collision or abnormality occurs, thereby reducing the start-stop time while maintaining reliable engine stop function.
2Reliability
If the engine completes the start according to the start instruction, then the engine start function is achieved, but vehicle and personal safety may be compromised during collision or abnormality
Solution Approach 1:
The control unit receives start prohibition information in advance and determines whether to prohibit engine start before the engine start instruction is executed. This preliminary anti-action prevents the engine from starting during collision or abnormality conditions, eliminating the safety risk associated with engine operation during hazardous events while maintaining the engine start function under normal conditions.
3Reliability
If the engine stop prohibition request is withdrawn when engine stop request has priority, then the engine stop function is ensured, but the response to driver intent and vehicle conditions is delayed
Solution Approach 1:
The control unit dynamically determines whether to prohibit engine start based on the reception timing of start prohibition information relative to the engine start instruction. This dynamic approach allows the system to adapt its behavior according to the specific timing and conditions, ensuring engine stop function is maintained while improving response to driver intent and vehicle conditions by making real-time decisions rather than following fixed priority rules.

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.
