The present invention relates to a braking technology of a vehicle, and in particular to an electromechanical brake (EMB) system with redundant power supply. The electromechanical brake system comprises a recharging power source () and at least two control modules () corresponding to axles () of a vehicle. The control modules () comprise a power supply unit () that supplies power to electric brake devices () disposed at opposite ends of a corresponding axle () in response to an operation demand. The power supply unit () is charged by the recharging power source (). The power supply unit () of at least one of the control modules () is configured with redundancy.

Electromechanical braking system

The present invention provides an electro mechanical brake () comprising an electrical actuator () which can simplify the structure of the electro mechanical brake () by integrating a control module () into a motor housing (). The electrical actuator () may comprise a motor housing (), a motor () provided inside the motor housing (), and a control module () for controlling the motor (), wherein the control module () is inside the motor housing ().

Electro mechanical brake and electrical actuator thereof

The present application provides an electromechanical brake and the controlling method thereof, and an electromechanical braking system, relate to the technical field of brake, the electromechanical brake comprising an electric motor and an electromagnetic brake, the electric motor having a shaft and outputting a torque based on a braking demand, and the electromagnetic brake being configured for locking and releasing the shaft, the controlling method comprises controlling the electric motor and the electromagnetic brake based on the braking demand; controlling a power supply of the electromagnetic brake when the electromagnetic brake needs to release or lock the shaft; obtaining a target current value corresponding to the real-time temperature value based on temperature-current relationship data; and when a difference between the real-time current value and the target current value is greater than a preset range, adjusting a duty cycle of the driving voltage level. By obtaining the real-time current value to compare with a target current value to determine whether the driving voltage level of the electromagnetic brake needs to be adjusted or not, and in the case of need, adjusting the driving voltage level by adjusting the duty cycle, the electromagnetic brake can be adjusted to a desired operating state as quickly as possible, thereby reducing the power consumption of the electromagnetic brake.
