A DC injection brake system can be used as an alternative or addition to a friction brake system. DC injection brakes only require a small module located with the other motor switchgear and/or drivers, mounted in a remote and convenient location, whereas a friction brake must be mounted somewhere on the rotating system.
The use of both braking systems at the same time is called blended braking. Li-ion batteries have also been used to store energy for use in bringing trains to a complete halt. [1] Although blended braking combines both dynamic and air braking, the resulting braking force is designed to be the same as the air brakes on their own provide.
A braking chopper is an magnetical switch that limits the DC bus voltage by switching the braking energy to a resistor where the braking energy is converted to heat. Braking choppers are automatically activated when the actual DC bus voltage exceeds a specified level depending on the nominal voltage of the variable-frequency drive
Braking unit also some times referred as Dynamic braking unit may refer to: DC injection braking unit, an electrical braking device for ac motors; Regenerative braking unit, regenerative braking systems used in traction motors; Electromagnetic brake, devices using electromagnetic forces to mechanically brake
CBC uses the vehicle's electronic control unit and ESC to receive data from multiple sensors. These sensors calculate variables such as speed, acceleration, yaw rate, and steering angle. [16] CBC then uses these variables to adjust brake pressure, desired yaw rate, brake steer torque, and stopping distance.
In a brake-by-wire car, some sensors are safety-critical components, and their failure will disrupt the vehicle function and endanger human lives. Two examples are the brake pedal sensors and the wheel speed sensors. The electronic control unit must always be informed of the driver's intentions to brake or to stop the vehicle. Therefore ...

Electronic speed control – or ESC is an electronic circuit with the purpose to vary an electric motor's speed, its direction and possibly also to act as a dynamic brake. Computer simulation – a computer model, or a computational model is a computer program, or network of computers, that attempts to simulate an abstract model of a particular ...
