Push-Start Remote Start Control for Full Takeover Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aftermarket systems do not support Full Take Over (FTO) functionality, which allows remote starting, opening doors, and operating a vehicle without engine shutdown, reducing security concerns and limiting features like maintaining interior temperature and reducing engine wear, especially in vehicles like the 2018 Toyota Prius that do not have this feature as a built-in option.
Innovation Solution
The system detects a remote start request, emulates an electrical brake pedal press, activates the vehicle's start switch, and determines if the vehicle is started, ensuring secure operation by only allowing the vehicle to be driven when the RSA system is disarmed and the driver possesses the aftermarket key fob, using methods like modifying brake pedal status, detecting engine signals, and timing out if the vehicle does not start within a certain period.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If Full Take Over functionality is implemented to allow remote starting and operation without engine shutdown, then the ability to maintain interior temperature and reduce engine wear is improved, but vehicle security is worsened
Solution Approach 1:
The patent introduces an aftermarket control system as an intermediary between the key fob and the vehicle's existing security and starting systems. This intermediary captures and processes key fob signals, emulates brake pedal presses, and controls the push-to-start button, thereby enabling FTO functionality while maintaining security through controlled access via the key fob.
Solution Approach 2:
The system creates a copy of the legitimate driver's access method by capturing key fob signals and emulating the authorized starting sequence. The control system replicates the brake press and start button press actions that would normally be performed by the driver, allowing remote operation while maintaining security through signal authentication.
2Reliability
If manual starting is restricted to when the system is disarmed, then security is improved, but the ability to operate the vehicle remotely with full control is worsened
Solution Approach 1:
The system performs preliminary actions by capturing the key fob signal before the actual starting sequence is initiated. The control system processes the remote start request, verifies security conditions, and prepares the vehicle systems in advance, allowing the engine to start remotely while maintaining security protocols through pre-validated key fob authentication.
Solution Approach 2:
The patent replaces the mechanical requirement of physically being present to press the start button and brake pedal with an electronic system that captures remote key fob signals and automatically emulates the necessary mechanical actions. This substitution enables remote operation while maintaining the security constraint that only authenticated key fob holders can initiate starting.

AI summary
Full take over (FTO) of a vehicle permits a vehicle operator to remote start the vehicle, open one or more doors, enter the vehicle, and operate the vehicle without any engine shutdown. FTO may be achieved by a system for: detecting a remote start request, activating a key fob to allow for reading a security code, emulating an electrical brake pedal press, emulating an activation of the vehicle's start switch, and determining whether the vehicle is started. The vehicle driver may thereby unlock the vehicle, open the vehicle door, and drive the vehicle without the vehicle shutting down.
