Actuator Initiated Launch Control System for Vehicle Drift
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High performance vehicle control functions such as drift, burnout, and launch are typically performed manually, requiring driver skill and experience, and there is a need for assistance to achieve consistent and efficient execution of these functions.
Innovation Solution
A vehicle control system that includes a brake assembly, a propulsion system, and processing circuitry coupled with a hand-operated actuator to automatically initiate and control braking and propulsive forces based on operator intent, using sensors and algorithms to determine vehicle speed and actuator positions to execute drift, burnout, and launch operations.

Engineering Contradiction Analysis
1Reliability
If manual operation of vehicle controls is used for drift, burnout, and launch functions, then the driver has full control over the vehicle, but the execution consistency and efficiency are limited by driver skill level and experience
Solution Approach 1:
The system enables automatic control functions to assist the driver in executing drift, burnout, and launch operations. The processing circuitry automatically controls the brake assembly and propulsion system based on detected operator intent, reducing dependency on driver skill while maintaining driver initiation and oversight.
Solution Approach 2:
The system continuously monitors vehicle speed, actuator positions, and operator inputs to detect intent for drift, burnout, or launch functions. This feedback mechanism allows the system to automatically adjust brake and propulsion forces in real-time, ensuring consistent execution regardless of driver experience level.
2Productivity
If automatic control functions are introduced to assist drift, burnout, and launch operations, then execution consistency and efficiency are improved, but the system complexity increases
Solution Approach 1:
The processing circuitry is designed to handle multiple functions (drift, burnout, and launch operations) through a single integrated system. The same circuitry detects operator intent and controls both the brake assembly and propulsion system across all three functions, reducing overall system complexity compared to having separate systems for each function.
Solution Approach 2:
The system combines the detection of operator intent and the control of brake and propulsion systems into a single integrated control process. The processing circuitry simultaneously monitors multiple inputs and coordinates multiple outputs, merging what could have been separate control systems into one unified architecture.
3Measurement precision
If the processing circuitry automatically applies balancing brake force based on propulsion actuator actuation, then the propulsive forces are precisely controlled, but the response time for manual intervention may be delayed
Solution Approach 1:
The system applies balancing brake force automatically as the propulsion actuator is actuated, before the vehicle reaches threshold speed. This preliminary automatic control establishes precise force balance early in the operation, reducing the need for later manual adjustments and maintaining precision throughout the maneuver.

AI summary
A control system for a vehicle may include a brake assembly having a brake actuator that operates brakes to apply braking forces to wheels of the vehicle when actuated, a propulsion system having a propulsion actuator operable to apply propulsive forces to at least some of the wheels when actuated, a hand-operated actuator, and processing circuitry operably coupled to the hand-operated actuator, the propulsion system, and the brake assembly to apply a balancing brake force to balance the propulsive forces generated based on actuation of the propulsion actuator while the vehicle is below a threshold speed and both the hand-operated actuator is actuated and the brake actuator is not actuated, and release the braking forces when the hand-operated actuator is released.
