Abstract: The present disclosure provides a method, device, and vehicle of pre-warning for a vehicle collision. The present disclosure may acquire two images captured by two photographing devices with respect to an obstacle; perform calculation on the two images based on close-range photogrammetry to obtain a distance between the obstacle and the rear of the vehicle; and making a pre-warning for a vehicle collision when the distance is less than a preset threshold. Because the photographing devices may utilize an inherent reversing camera of the vehicle, and avoid additionally providing an anti-knocking radar system, so that it is possible to solve the technical problem in the related art that the system cost for the anti-knocking radar system may be high, which causes difficulty in popularizing.

Abstract: The present disclosure provides aroad-surface detecting system and vehicle. The road-surface detecting system may include an anti-knocking radar system and a control system, wherein the anti-knocking radar system may be configured to measure distance data for the distance from the chassis of the vehicle and the road surface and transmit the distance data to the control system, and the control system may be configured to determine that the road is a bumpy road surface if change of the distance data is more than a preset distance changing value.The road-surface detecting system provided by the present disclosure may reduce the detecting cost by detecting the bumping conditions of the road surface on which the vehicle is currently riding by the anti-knocking radar system and control system mounted on the vehicle.

Abstract: The present disclosure provides a method of computing routes for multiple-user's commutes and apparatus thereof. Wherein, the method includes: locating each of the multiple users to obtain a location coordinate of each of the multiple users; computing the central point or central zone according to the location coordinates of the multiple users, wherein the central point or central zone is a visual center or central zone; recommending a route to said multiple users based on said central point or said central zone, respectively, the present disclosure makes sure that each user takes about the same time to arrive at the meeting location, thus avoiding time being wasted in waiting one or another user.

Abstract: The present disclosure discloses a remote control method and device, the method including: establishing Beidou short message connection with a second apparatus; authorizing control permission to the second apparatus via the Beidou short message connection; and receiving and executing a control command in accordance with the control permission from the second apparatus via the Beidou short message connection. The present disclosure may avoid the problem that the remote unlocking cannot be responded in time due to instable signal connection. Thusly, the faulted vehicle can be controlled remotely fast and in time, the efficiency of remote control may be increased, and the data traffic cost may be reduced.

Abstract: The present disclosure provides a vehicle operation control method, and related devices and system. The vehicle operation control method includes: receiving a first vehicle operation instruction sent by a user terminal over a cellular network, wherein the first vehicle operation instruction carries a vehicle identifier of an operated vehicle, and vehicle operation information; searching stored correspondence relationships between vehicle identifiers and satellite positioning terminal identifiers for a identifier of a satellite positioning terminal installed in the operated vehicle according to the vehicle identifier; and sending a second vehicle operation instruction to a satellite ground station, wherein the second vehicle operation instruction carries the found satellite positioning terminal identifier and the vehicle operation information.
