Ola Electric’s Patent for Automatic Deactivation of Turn Indication. If you’ve ever driven for minutes with your signal blinker still on, you know how distracting and dangerous a forgotten turn signal can be! A new international patent application from Ola Electric Mobility Limited proposes a smarter, sensor‑driven way to switch indicators off automatically reliably, across real‑world scenarios where conventional cam‑based cancel mechanisms fail.

Ola Electric’s Patent for Automatic Deactivation of Turn Indication – Basic patent details:

Ola Electric’s Patent for Automatic Deactivation of Turn Indication – What problem does the invention solve?

Traditional auto‑cancel systems depend on steering angle return or mechanical cams in the handlebar/column. They struggle with:

• Slow or gradual lane changes where steering return is minimal
• Paused turns (driver signals and waits before turning)
• Roundabouts and multi‑stage manoeuvres
• Variability in user behaviour that confuses simple angle/timeout thresholds

Ola Electric’s Patent for Automatic Deactivation of Turn Indication – Key innovation: IMU‑driven logic with adaptive thresholds:

The disclosed system places an Inertial Measurement Unit (IMU) at the core of its logic. By analysing rotational rates and acceleration vectors, the controller can:

• Detect the onset of a turn with high confidence
• Track the manoeuvre’s progress
• Decide when the turn is actually completed not merely when the wheel straightens momentarily

The patent describes four decision thresholds to robustly recognise both turn initiation and completion. These thresholds help distinguish genuine turns from minor steering corrections and reduce nuisance cancellations during lane keeping.​

Ola Electric’s Patent for Automatic Deactivation of Turn Indication – Edge‑case handling:

A standout feature is the explicit handling of tricky real‑world cases:

• Slow/gradual lane changes where steering angle remains small for a long time
• Situations where the rider/driver activates the indicator, then pauses before executing the turn
• Multi‑phase manoeuvres such as roundabout exits

The logic uses state transitions and confidence scoring to keep the indicator on when needed and cancel it only when the manoeuvre is truly over.​

Ola Electric’s Patent for Automatic Deactivation of Turn Indication – Data science model with personalization:

Beyond fixed thresholds, the system includes a data‑science model that:

• Consumes IMU signals and other variables
• Computes confidence intervals for decisions
• Learns user‑specific behaviour patterns over time

This adaptive layer personalizes the cancellation timing, aiming to reduce both premature cancellations and lingering indicators for different driving styles and vehicle configurations.​

Ola Electric’s Patent for Automatic Deactivation of Turn Indication – How it likely integrates in vehicles?

• Sensors: A low‑cost IMU already common in modern two‑wheelers and EVs feeds the algorithm
• Controller: Embedded logic in the BCM/indicator module maps IMU events to indicator states
• Inputs/outputs: Works alongside existing stalk/switch inputs and indicator lamps; can be over‑the‑air updated in connected vehicles

Ola Electric’s Patent for Automatic Deactivation of Turn Indication – Benefits for riders, drivers, and fleets:

• Safety: Fewer misleading signals reduce side‑swipe and intersection risks
• User experience: Hassle‑free, context‑aware cancelation without constant manual correction
• Compliance: More consistent signalling behaviour supports regulations and testing standards
• Fleet operations: For shared scooters and ride‑hail fleets, consistent indicator control reduces incident rates and maintenance calls

Ola Electric’s Patent for Automatic Deactivation of Turn Indication – Competitive landscape and IP positioning:

Indicator auto‑cancel features exist, but many rely solely on steering angle or distance/time heuristics. Invention discloses in this patent is differentiates with:

• Multi‑threshold IMU logic to establish initiation and completion states
• Specific handling of gradual lane changes and delayed‑turn scenarios
• A learning model that personalizes decisions using confidence intervals

These elements can support claims that are difficult to design around if they’re tied to particular IMU feature sets, thresholds, and state machines described in the specification.

Ola Electric’s Patent for Automatic Deactivation of Turn Indication – Potential applications:

• Two‑wheelers and scooters where steering return is limited and lane changes are frequent
• Compact EVs and city cars targeting advanced ADAS features at low cost
• Retrofit modules for fleets seeking safety upgrades without replacing hardware

Ola Electric’s Patent for Automatic Deactivation of Turn Indication – What to watch next:

As the application enters national phases, look for:

• Claim scope around the four thresholds and completion detection logic
• The breadth of the “data science model” language and training inputs
• Integration claims with other ADAS sensors (camera, GNSS) for sensor fusion

Ola Electric’s Patent for Automatic Deactivation of Turn Indication – Conclusion:

Ola Electric’s Patent for Automatic Deactivation of Turn Indication presents a practical, sensor‑first approach to automatic indicator deactivation that addresses long‑standing weaknesses of mechanical and simple heuristic systems. By blending IMU analytics with adaptive, personalized decision‑making, the invention aims to deliver safer, more intuitive signalling for riders and drivers particularly in two‑wheelers and urban EVs where conventional auto‑cancel systems fall short.
