Abstract: A mobile terminal positioning method, comprising: acquiring the ranging distances between a plurality of UWB base stations and a mobile terminal in the current period; according to the plurality of ranging distances, determining, from among a plurality of preset areas, a target area where the mobile terminal is located in the current period; and calculating the positional coordinates of the mobile terminal in the current period according to the target area where the mobile terminal is located in the current period, and the ranging distances between the plurality of UWB base stations and the mobile terminal in the current period.

Abstract: A system for vehicle power control includes: a control apparatus, a first driving motor, a generator, an engine, a driving motor electricity supply loop and a bypass branch. The driving motor electricity supply loop and the bypass branch are connected in parallel, and are positioned between the first driving motor and the generator. The generator is in mechanical transmission connection with the engine. The driving motor electricity supply loop is provided with a first motor controller and a second motor controller. The first motor controller is electrically connected to the first driving motor; the second motor controller is electrically connected to the generator. The bypass branch is provided with a switching element. The control apparatus is configured to, in response to a speed meeting a preset speed condition, control the second motor controller to stop working, and control the switching element to be turned on to conduct the bypass branch.

Abstract: A method for vehicle charge control includes: acquiring a proportional relationship between an estimated charging cost and an estimated charging time and a target charging quantity of electricity; determining the estimated charging cost and the estimated charging time according to the target charging quantity of electricity and the proportional relationship between the estimated charging cost and the estimated charging time; and determining an actual control sequence for performing an actual charge control on the vehicle according to the target charging quantity of electricity, the estimated charging cost and the estimated charging time, in which the actual control sequence is a sequence consisting of control signals issued to a component related to charging of the vehicle when the vehicle is charged.
