Abstract: A hydraulic active suspension for a vehicle includes: a shock absorber, a common channel, an accumulator module, and a liquid storage apparatus. The shock absorber has a housing, a piston, and a piston rod. The housing is adapted to be connected to a wheel or an axle. The piston is located in the housing and defines an upper chamber and a lower chamber of the shock absorber. One end of the piston rod is connected to the piston. The other end of the piston rod projects out of the housing and is adapted to be connected to a body. Both the liquid storage apparatus and the accumulator module are in communication with the lower chamber through the common channel. The liquid storage apparatus is configured to adjust a height of the vehicle. The accumulator module is configured to adjust at least one of stiffness and damping of the shock absorber.

Abstract: The present disclosure provides a power conservation control method and apparatus for a vehicle, and a readable storage medium. The method part includes: obtaining a minimum predicted ambient temperature within a preset time period; determining a minimum ambient temperature according to the minimum predicted ambient temperature and a current ambient temperature; if the minimum ambient temperature is less than or equal to a first preset temperature threshold, determining a minimum power conservation point of a traction battery according to the minimum ambient temperature; and performing mandatory power conservation control on the vehicle according to the minimum power conservation point, so that the remaining power of the traction battery is not less than the minimum power conservation point.
