Vehicle Controller Default Action Trigger Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems require manual activation and deactivation of secondary tasks, leading to inefficiencies and unintended behavior when dealing with overlapping trigger conditions, such as geofenced locations, temperature, and time settings.
Innovation Solution
A controller system that processes user-defined actions and default actions based on trigger conditions like vehicle location, time, temperature, and humidity, eliminating the need for explicit exit conditions by using a processor to generate control signals for vehicle systems upon meeting start and default trigger conditions.

Engineering Contradiction Analysis
1Extent of automation
If a vehicle system is programmed to perform actions when a given trigger condition is satisfied, then the system can be activated automatically, but the vehicle may not revert to the intended state when leaving a trigger location due to overlapping locations
Solution Approach 1:
The system pre-defines default actions and their associated trigger conditions during configuration. When the vehicle enters a trigger location, the processor determines whether a default action's trigger condition is met and executes the appropriate action, ensuring the system reverts to the intended state even when locations overlap.
2Ease of operation
If drivers manually control each secondary vehicle system, then precise control is achieved, but it becomes time consuming and inconvenient
Solution Approach 1:
The vehicle system performs secondary tasks automatically based on trigger conditions and pre-configured actions. The processor monitors trigger conditions (such as vehicle location, time, temperature, humidity) and executes corresponding actions without requiring driver intervention, making the system self-serve the driver's needs.
3Reliability
If explicit exit conditions are defined for each trigger location, then system behavior can be precisely controlled, but the complexity of managing multiple trigger events increases
Solution Approach 1:
The system uses a universal default action mechanism that can handle multiple trigger locations and overlapping conditions. Instead of defining specific exit conditions for each location, a single default action with its trigger condition serves multiple purposes across different scenarios, simplifying the overall system structure.

AI summary
A controller (200) for controlling a vehicle system (210), the controller comprising: an input (206) for receiving a configuration signal specifying an action to be carried out by a vehicle system in response to a trigger condition, the trigger condition being associated with a start condition; a memory module (204) arranged to store data indicative of the specified action and trigger condition, the memory module being further arranged to store data indicative of a default action to be carried out by the vehicle system in response to a default action trigger condition; a processor (202) arranged, upon the start condition being met to generate a control signal for controlling the vehicle system in accordance with the stored action; an output (208) arranged to output the control signal; wherein the processor is arranged to determine when, subsequent to the start condition being met, a default action trigger condition is met and to generate a further control signal for controlling the vehicle system in accordance with the stored default action.
