Vehicle Direction Sensing System Torque Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicles lack the ability to detect when they are being driven in the wrong direction and cannot provide feedback to the driver to correct this, posing safety risks and inefficiencies in traffic flow.
Innovation Solution
A system comprising a vehicle orientation sensor, GPS unit, and electronic control unit (ECU) that detects the vehicle's direction and location, communicates with the powertrain to reduce torque when driven in the wrong direction, and provides alerts to the driver through visual, auditory, and tactile means to encourage correction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system reduces torque to prevent wrong-way driving, then safety is improved, but vehicle performance and driver convenience deteriorate
Solution Approach 1:
The system continuously monitors vehicle location via GPS and orientation via sensors, compares this data against map information to detect wrong-way driving, and provides real-time feedback to the driver through alerts and torque reduction, creating a closed-loop control system that adapts to detected conditions
Solution Approach 2:
The system dynamically changes the torque parameter provided to the powertrain based on detected driving conditions, reducing torque when wrong-way driving is detected and restoring normal torque when the vehicle is properly oriented, allowing performance modulation to prioritize safety without permanently degrading vehicle capability
2Measurement precision
If the system continuously monitors vehicle direction and location, then detection accuracy is improved, but energy consumption and system complexity increase
Solution Approach 1:
The system pre-loads map data containing correct driving direction information into the ECU before operation, allowing for rapid comparison with real-time sensor data without requiring continuous complex calculations or additional data retrieval, thus maintaining high detection accuracy while minimizing processing energy consumption
Solution Approach 2:
The GPS unit and orientation sensors continuously self-monitor vehicle position and direction, automatically comparing against stored map data without requiring external intervention or complex processing, enabling sustained precise detection with minimal additional energy overhead

AI summary
Methods, systems, and apparatus for preventing a vehicle from driving in a wrong direction. The method includes detecting, via a vehicle orientation sensor, a current driving direction of the vehicle. The method also includes detecting, via a GPS unit, a current location of the vehicle. The method also includes providing, by a powertrain, torque to one or more wheels of the vehicle. The method also includes determining, by an electronic control unit (ECU), whether the vehicle is travelling in the wrong direction based on the current driving direction of the vehicle and the current location of the vehicle. The method also includes communicating, by the ECU, an instruction to the powertrain to reduce the torque provided to the one or more wheels of the vehicle when the vehicle is travelling in the wrong direction.
