Problems solved by technology

Since the traction and braking control are divided into two control modules, when the braking command is executed through electric-air hybrid braking, the traction control module needs to receive the electric braking force control command sent by the braking control module, and control the traction actuator to perform electric braking. Manual operation, that is, data interaction between the brake control module and the traction control module is required, which increases the data transmission delay and affects the accurate execution of the brake command
It is also because the traction and braking control are two independent control modules, and the topology of each module requires hardware resources such as MVB communication modules, IO input channels, analog input channels, etc., thus causing waste of hardware resources and increasing The complexity of the system reduces the reliability of the system
