System and method for coordinating and controlling driving and/or braking torques, and motor vehicle

A system for coordinating and controlling driving and/or braking torques in a vehicle, comprising:

• a first processing module configured to receive a request for a driving or braking torque of the vehicle, to process the received request according to specifications for the vehicle, and to divide the processed request between multiple axles of the vehicle;
• multiple second processing modules, each configured to receive a request for a driving or braking torque for a corresponding axle from the first processing module, to process the received request according to specifications of the corresponding axle, and to divide the processed request as accelerating or decelerating wheel torques between corresponding wheels of the corresponding axle;
• multiple third processing modules, each configured to receive a request for a driving or braking torque for a corresponding wheel from one of the second processing modules and to process the received request according to specifications of the corresponding wheel of the corresponding axle;
• multiple fourth processing modules, each configured to receive a processed request for a driving or braking torque for a corresponding wheel from one of the third processing modules, to process the received processed request according to specifications for an actuator to be controlled, and to provide a corresponding control signal to the actuator to be controlled.

A motor vehicle, comprising:

• a drive system configured to drive and/or decelerate wheels of the motor vehicle;
• a brake device configured to brake wheels of the motor vehicle;
• and
• a system configured to coordinate and control driving and/or braking torques, the system including:
• a first processing module configured to receive a request for a driving or braking torque of the vehicle, to process the received request according to specifications for the vehicle, and to divide the processed request between multiple axles of the vehicle,
• multiple second processing modules, each configured to receive a request for a driving or braking torque for a corresponding axle from the first processing module, to process the received request according to specifications of the corresponding axle, and to divide the processed request as accelerating or decelerating wheel torques between corresponding wheels of the corresponding axle,
• multiple third processing modules, each configured to receive a request for a driving or braking torque for a corresponding wheel from one of the second processing modules and to process the received request according to specifications of the corresponding wheel of the corresponding axle, and

A method for coordinating and controlling driving and/or braking torques in a vehicle, comprising the following steps”

• receiving a request for a driving or braking torque of the vehicle;
• processing the received request for the driving or braking torque of the vehicle according to specifications for the entire vehicle;
• dividing the request for the driving or braking torque processed according to the specifications for the entire vehicle, between multiple corresponding axles of the vehicle;
• processing the request for the driving or braking torque divided between the multiple corresponding axles of the vehicle, in each case according to specifications of the corresponding axle of the vehicle;
• dividing the request for the driving or braking torque processed according to the specifications for the corresponding axles, between multiple corresponding wheels of the corresponding axle of the vehicle;
• processing the request for the driving or braking torque divided between the multiple corresponding wheels of the axles of the vehicle, in each case according to specifications of the corresponding wheel of the vehicle;
• processing the request for the driving or braking torque processed according to the specifications for each of the corresponding wheels, according to the specifications of an actuator to be controlled;
• and
• providing control signals to the actuators by using the requests for the driving or braking torque processed according to the specifications of the actuators.
