Title:
VEHICLE POWER RECOVERY METHOD AND SYSTEM, AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2024/055841
Kind Code:
A1
Abstract:
The embodiments of the present application belong to the technical field of automatic vehicle control. Provided are a vehicle power recovery method and system, and a vehicle. The method specifically comprises: a sensor subsystem acquiring the current wheel speed; an accelerator subsystem acquiring a target vehicle body speed; and a control subsystem determining according to the current wheel speed and the target vehicle body speed that a vehicle reaches a target rear-wheel torque corresponding to the target vehicle body speed, wherein when the target rear-wheel torque is a deceleration torque, the control subsystem selects a braking mode according to a braking priority algorithm, so as to decelerate the vehicle, and the braking mode comprises at least one of a regenerative braking mode, a reverse torque braking mode of an electric motor, and a friction braking mode. By means of the solution of the present disclosure, the timing for using a regenerative braking mode is accurately determined, such that the effect of energy recovery is improved, and it is ensured that electric energy which is obtained via conversion performed by means of the regenerative braking mode can be completely stored.
