Abstract: A method for flashing an electronic control unit includes: obtaining a request message to be processed, the request message including an identification (ID) of a target domain and an ID of an electronic control unit to be flashed; at a starting moment of a reception time slot corresponding to the electronic control unit, sending the request message to the electronic control unit through the target domain based on the ID of the target domain and the ID of the electronic control unit; and at a starting moment of a transmission time slot corresponding to the electronic control unit, receiving a response message generated by the electronic control unit based on the request message through the target domain.

Abstract: The present invention discloses a power transmission control method and device for a crane and the crane. The method includes: setting the maximum working displacement of a secondary element corresponding to each gear of the crane; determining the current gear state and specific gear of the crane; determining the working mode of the secondary element from the gear state, and setting the maximum allowable displacement of the secondary element as the maximum working displacement corresponding to the specific gear.

Abstract: A power transmission control method and device for a crane and the crane includes setting the maximum working displacement of a secondary element corresponding to each gear of the crane; determining the current gear state and specific gear of the crane; determining the working mode of the secondary element from the gear state, and setting the maximum allowable displacement of the secondary element as the maximum working displacement corresponding to the specific gear. In the power transmission control method and device for the crane and the crane of the present invention, the maximum displacement of the secondary element is controlled for various gears, which can reduce power impact. A buffer mode is added to avoid influence on a vehicle due to loss of instant power generated at the moment of energy release completion and avoid vehicle jitter due to instable power resulting from the vehicle at low speed or a system suddenly disconnected.
