Patent ID: 8246120

Claim:
An electrical braking system for a road vehicle fitted with wheels, each wheel being connected for rotation to at least one rotary electrical machine such that each rotary electrical machine cooperates with a single wheel, each wheel including an electronic wheel control module controlling the at least one rotary electrical machine of the wheel, each electronic control module being configured to impart selectively to a corresponding wheel a control torque of determined amplitude and sign such that the corresponding wheel imparts to the vehicle a longitudinal drive force or a longitudinal braking force in accordance with the control torque, the electrical braking system comprising: a central unit for managing a longitudinal displacement of a vehicle, the central unit controlling all electronic wheel control modules of wheels of the vehicle, wherein the central unit has a vehicle braking mode activated by a vehicle braking control signal having an amplitude representing a total desired braking force for the vehicle such that, in the braking mode, the central unit controls all the electronic wheel control modules so that a sum of longitudinal forces of all the wheels, outputted by the rotary electrical machines of the wheels, is a function of the amplitude of the braking control signal, and means for thermally dissipating electrical energy, with a power in excess of 350 kW per ton of the vehicle, wherein all of the rotary electrical machines are able to output a peak power greater than 350 kW per ton of the vehicle.
