Volkswagen study pairs hydraulic and electric brakes to cut friction
Volkswagen's Mission Efficiency study uses a new braking setup in an electric car designed for high efficiency.
It combines hydraulic braking at the front with electromechanical braking at the rear.
The system is supplied by Aumovio, which also provides braking equipment for the Volkswagen ID.
Polo.
At the front, a one-box system is designed to work with regenerative braking, which recovers energy as the car slows.
The electronic brake-by-wire system sends braking commands without connecting the pedal directly to the hydraulic pressure system.
Volkswagen says the larger gap between pads and discs should reduce unwanted friction, with rear brake losses intended to approach zero.
The setup is meant to make the car more efficient, but no further next steps are given.
Volkswagen’s Mission Efficiency study combines hydraulic and electromechanical braking to reduce friction in an electric vehicle.
Aumovio supplies the system, which uses optimized hydraulic calipers and a One-Box brake system at the front, and electromechanical brakes at the rear.
The study increases the clearance between the brake discs and pads at both axles compared with a production vehicle.
Volkswagen says the design aims to reduce unwanted friction while balancing low drag with quick brake response.
Aumovio says rear-axle brake friction losses are intended to fall almost to zero.
