Description

Method and Device for Operating Brakes of a Vehicle The disclosed content relates to a method and device for operating a vehicle brake. Delivery drivers disembark from their vehicles to deliver items. While the principle is to turn off the engine when exiting the vehicle to prevent accidents, drivers frequently move the vehicle with the engine running for the sake of convenience.
