Abstract:
An electronic braking system with independent antilock braking and stability control. The system can utilize a variety of electro-mechanical actuators to apply clamping force to a mechanical brake caliper. The system can include a caliper electronic control unit (CECU) and a wheel speed sensor at each wheel of the vehicle to enable independent slip control, or antilock braking, at each wheel. A separate executive management unit (EMU) can receive data from each electronic caliper, vehicle accelerometers, and other sensors to provide electronic stability control (ESC) independent of antilock braking (ABS) functions. The removal of a conventional master cylinder, brake pedal, ABS pump, brake lines, and other components can reduce weight and complexity. The elimination of hydraulic lines running to a central ABS module and master cylinder can enable modular drive units to be swapped out more quickly and efficiently.
