It moves back while carrying out, and send electric braking force to EBCU there is no DCU and subside completely signal, EBCU receives electric braking force and disappears completely
The network delay of the process is also just not present in this process of bounce number, then the braking in the available embodiment turns traction
Maximum delay is 2.87 seconds, also avoids to turn the abnormal block of traction caused by the delay of traction due to braking.Such as existing skill
DCU sends electric braking force and subsides completely signal in art, and the network that EBCU receives electric braking force this process of recession signal completely prolongs
When be 0.6 second, and in a particular embodiment, air brake force subsides completely needs 1 second, then in the embodiment of this programme,
At least reduce delay in 1.6 seconds.
