Vehicle Remote Start Controller Using Lock Button Press Duration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote start controllers for vehicles require multiple transmitters, making them cumbersome to use, and existing solutions complicate the transmitter configuration with mode change switches or antenna position changes, lacking simplicity and security, especially when used in locations where the vehicle is not in sight.
Innovation Solution
A remote start controller that uses a keyless entry device's lock button to start and stop the engine, simplifying the transmitter configuration by detecting button operations through reception information or drive signals, ensuring safety and security by keeping the vehicle's doors locked during engine operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a common transmitter is used for both keyless entry and remote start control, then the number of transmitters to carry is reduced, but the operation becomes inconvenient since door locking/unlocking and engine start/stop are combined
Solution Approach 1:
The patent applies periodic action by using different pressing durations of the same lock button to trigger different functions. Short pressing (first predetermined period) activates door locking, while long pressing (second predetermined period longer than first) activates engine starting. This temporal differentiation allows a single button to control multiple functions without confusion, resolving the contradiction between using fewer transmitters and maintaining operational convenience.
2Reliability
If the lock button operation period is set to be long for engine starting, then the engine can be started reliably, but the door locking operation becomes slow and inefficient
Solution Approach 1:
The patent differentiates between short pressing for door locking and long pressing for engine starting. The lock button control section detects the pressing duration and activates different functions accordingly. This allows door locking to be performed quickly with a short press, while engine starting requires a deliberately held long press, ensuring reliable engine activation without compromising the speed of door locking operations.
3Device complexity
If the lock button is used for both door locking and engine starting, then the transmitter configuration is simplified, but the detection and measurement of operation intent becomes more difficult
Solution Approach 1:
The patent uses the pressing duration (period) of the lock button as the differentiating factor. The control section measures the time period of button pressing and determines the user's intent based on whether it exceeds the predetermined threshold. This temporal measurement provides a clear, objective criterion for distinguishing between door locking and engine starting commands, simplifying the transmitter while maintaining accurate detection of operation intent.

AI summary
A remote start controller is mounted on a vehicle, which includes a keyless entry device for controlling a locking action of doors of the vehicle in response to a user's operation with respect to a lock button of a transmitter. The remote start controller includes a CPU. Upon detecting that the lock button of the transmitter is operated in a first predetermined way, the CPU causes an engine of the vehicle to start.
