Abstract: A map display method comprises: obtaining room map data and regional map data; drawing a room map according to the room map data, and drawing a regional map layer on the room map according to the regional map data; and displaying the room map that is covered by the regional map layer.

Abstract: Disclosed are a dual-motor multi-gear hybrid transmission system and a vehicle. The dual-motor multi-gear hybrid transmission system includes an engine, a first motor, a second motor, a first clutch, a second clutch, a first planet row, a second planet row, a first input shaft, a second input shaft, a third input shaft and a brake assembly. The first input shaft is connected to the engine through the first clutch. The second input shaft is connected to the engine through the second clutch, and the second input shaft is sleeved outside the first input shaft. The first motor is connected to the engine. The second motor is connected to the first planet row through the third input shaft. The brake assembly is configured to brake the first planet row and/or the second planet row.

Abstract: A method to intercept an universal serial bus (USB) related request and to respond the intercepted request in a virtualized environment includes connecting a virtual USB peripheral controller in a virtualization software in the virtualized environment to a virtual machine in the virtualized environment. An USB data access request generated by the virtual machine may be intercept by the virtual USB peripheral controller so that the USB data access request does not reach a kernel space of the virtualization software and physical hardware resources supporting the virtualized environment. The method further includes generating a response according to the USB data access request and a process called by a firmware framework module of the virtual USB peripheral controller and transmitting generated response towards the virtual machine.
