The embodiment of the invention discloses a vehicle speed planning method, device and equipment. The method comprises the steps that driving path planning information of a target vehicle in a future preset time period is acquired; determining a first incidence relation among the target function, the boundary condition matrix and the decision variable matrix based on the driving path planning information; determining a second incidence relation among the first target matrix, the boundary condition matrix and the decision variable matrix; according to the first association relationship and the second association relationship, based on matrix operation, calculating a target solution of a corresponding first target matrix when the target function reaches a minimum value; obtaining a vehicle jerk in a target solution of the first target matrix, and obtaining a target jerk sequence of the target vehicle in a preset time period; and determining a target speed sequence of the target vehicle in a preset time period according to the target jerk sequence. According to the scheme, the vehicle speed planning solving success rate and the calculation efficiency are improved, and the calculation resources and the calculation time are saved.
