How far can you get without a friction brake on rear axle? The RABBIT project

By eliminating the mechanical friction brake, the wear parts in the power train are eliminated, which reduces costs, maintenance and also enables savings in weight and space. In addition, the emission of particulates by brake wear are eliminated. A braking resistor allows the use of the energy that is applied during braking to the thermal management of the entire vehicle, thereby extending the vehicle's driving range. This paper will present the concept of a fault-tolerant and functionally safe electric drive train with alternative energy sources that meets the brake requirements and at the same time enables a complete electrical and thermal utilization of the energy generated during braking.
