Mercedes-Benz has filed a new patent with the European Patent Office for an innovative folding brake pedal system designed for vehicles with autonomous or semi-autonomous driving modes. This system enhances driver comfort by retracting the brake pedal when self-driving is engaged, while advanced sensors and controls ensure a seamless and rapid transition back to manual driving with a simple driver input.
Seamless Manual Control Transition
In vehicles equipped with semi-autonomous or autonomous driving modes, Mercedes-Benz has introduced a retractable brake pedal that moves toward the floor when self-driving is engaged. This innovation provides the driver with increased space and freedom of movement while the vehicle handles driving tasks. The patent aims to establish a convenient and reliable method for restoring the pedal to its functional position when the driver decides to take control.
Key Components:
- Adjustable Pedal Mechanism – Positions the brake pedal in either comfort or usable mode.
- Driver Intent Sensors – Detect when the driver wants to take over.
- Control System – Manages smooth transitions between autonomous and manual driving.
- Redundant Safety Measures – Ensures 100% reliable operation at all times.
Retractable “Confirmation Pedal”
Upon engagement of autonomous driving, the pedal will go into a rest or comfort position, giving the driver more space. Mercedes says that this “confirmation pedal” can be either the accelerator or the brake. The vehicle monitors the driver’s intent via sensors to determine whether the pedal is required, swiftly restoring the pedal to its functional position. A control system then ensures a smooth handover from the car to the driver.
While Mercedes-Benz has not disclosed specific details about the sensors used, it’s likely they could include foot movement sensors, hands-on-wheel detection, or even voice commands or a physical switch to signal the driver’s intent.
What sets this patent apart is its combination of sensor and actuator technology, designed to create a fluid, intuitive transition between autonomous and manual driving modes. By ensuring that the pedal repositions itself precisely when needed, Mercedes aims to enhance both driver comfort and safety in future autonomous vehicles.
