METHOD FOR BRAKING A VEHICLE AND BRAKE CONTROL SYSTEM FOR A VEHICLE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18257943 titled 'METHOD FOR BRAKING A VEHICLE AND BRAKE CONTROL SYSTEM FOR A VEHICLE
Simplified Explanation
The abstract describes a method for braking a vehicle using an electric machine operated as a generator, with a damping control function to reduce periodic deflection of the drive train relative to the rotor shaft.
- The torque generated by the electric machine is controlled by a damping control function to reduce drive train deflection.
- A braking request signal representing a target braking torque is detected.
- The damping control function is deactivated based on a deactivation condition identified from the braking request signal.
- Braking torque is generated by operating the electric machine as a generator.
- The damping control function is reactivated when a reactivation condition is identified during the process of generating the braking torque.
Potential applications of this technology:
- Electric vehicles
- Hybrid vehicles
- Regenerative braking systems
Problems solved by this technology:
- Reducing periodic deflection of the drive train during braking
- Efficient braking control using an electric machine as a generator
Benefits of this technology:
- Improved braking performance
- Enhanced energy efficiency through regenerative braking
- Reduced wear and tear on the drive train components
Original Abstract Submitted
In a method for braking a vehicle with the aid of at least one electric machine, operated as a generator, of the vehicle, a torque generated by the electric machine is controlled by a damping control function in order to reduce a periodic deflection of a drive train, coupled to a rotor shaft of the electric machine, relative to the rotor shaft. Furthermore, a braking request signal representing a target braking torque is detected, a deactivation condition for deactivating the damping control function is identified on the basis of the braking request signal, the damping control function is deactivated when a deactivation condition is identified, a braking torque is generated based on the braking request signal by operating the electric machine as a generator, a reactivation condition for reactivating the damping control function is identified during the process of generating the braking torque, and the damping control function is reactivated when the reactivation condition is identified.
