Document Type and Number:
WIPO Patent Application WO/2024/093817
Kind Code:
A1
Abstract:
Disclosed are a braking control method and control device, and a computer-readable medium. The control method comprises the following steps: collecting a voltage value of a divider resistor R12; calculating a first bus voltage value by means of the voltage value of the divider resistor R12; detecting changes of a bus voltage within a first time by means of an MCU and calculating an average voltage change rate; estimating a second bus voltage value within a second time according to the average voltage change rate, wherein the second bus voltage value is an estimated bus voltage value; and determining the magnitude relationship between the estimated bus voltage value and a preset value, stopping slow braking when the estimated bus voltage value is greater than the preset value, and continuing to slow brake when the estimated bus voltage value is smaller than the preset value. According to the present invention, during slow braking, braking is performed in advance or stopped by means of estimating the bus voltage value, which solves the problems of voltage rise and electronic component damage during slow braking, and also avoids the problems of excessive direct braking torque, unstable braking transition and poor user experience.
