Document Type and Number:
WIPO Patent Application WO/2024/040881
Kind Code:
A1
Abstract:
Disclosed in the present application are a linear brake control method and apparatus applied to a competition-level remote-control model vehicle. The method comprises: a user sending, by means of a remote controller, a remote control instruction to an electric-motor control module of a model vehicle, wherein the remote control instruction comprises a brake instruction, which comprises the current accelerator value; when the remote control instruction is the brake instruction, the electric-motor control module selecting a corresponding brake algorithm according to the current rotating speed of a brushless electric motor, wherein if the current rotating speed of the brushless electric motor is greater than a first threshold value, an FOC brake control algorithm is selected according to the received remote control instruction, so as to control a brake current of the brushless electric motor, and if the current rotating speed of the brushless electric motor is less than or equal to the first threshold value, a PWM-control-based brake algorithm is switched to according to the received remote control instruction, so as to control the brake current of the brushless electric motor; and the brushless electric motor controlling the brake torque of a brake transmission system according to the brake current. Compared with the prior art, different brake control algorithms are selected according to different rotating speeds of an electric motor, and linear braking is realized by means of an FOC control algorithm.
