When Chang 'an vehicle is driving by video, remove the vehicle, unplug the speed sensor line and cancel it directly in the vehicle settings.

Unplug the speed sensor cable when getting off the train: the speed sensor cable can transmit the speed information to the train, and the train can judge whether the vehicle is moving by this information, so this restriction can be lifted only by unplugging this cable. First of all, we need to disassemble the car, then find the speed sensor line (yellow or white) in the A tail plug, and then cut it off.

train braking is to artificially stop the movement of the train, including slowing it down, not accelerating or stopping running. To relieve or weaken the braking effect of a braked train or locomotive is called "relieving". A set of equipment installed on the train for braking and relieving is called "train braking device". "Brake" and "braking device" are commonly called "brake". Braking is often referred to as "brake on" or "brake off", while relieving is referred to as "brake off".
