The present application discloses an adaptive braking method, a chip, a control device, and a motor vehicle, wherein the adaptive braking method includes obtaining the driving current flowing through the motor during the movement of the motor vehicle; determining the adjustment amount of the braking control signal according to the driving current; according to the adjustment amount, A brake control signal is determined, and the brake control signal is configured to control the motor vehicle to brake. Through the above method, the self-adaptive braking method of the present application can obtain the driving current to determine the adjustment amount of the braking control signal, so that the braking control signal can be used to control the braking of the motor vehicle to generate braking current. And because the adjustment amount of the brake control signal can be adjusted according to the counter electromotive force, it can prevent the excessive braking current from being generated in the control device of the motor vehicle, so that even if a transistor with a general current capacity is used in the control device, it will not be burned, thereby improving Cost-effectiveness and reliability of the entire control unit.
Description
technical field [0001] The present application relates to the technical field of motor vehicles, in particular to an adaptive braking method, a chip, a control device and a motor vehicle. Background technique [0002] At present, motor vehicles are widely used in China, and motor vehicles can be used for people's travel, cargo handling and so on. The motor vehicle is provided with a control device for braking. However, because some motor vehicles are not equipped with speed sensors, the motor vehicles cannot adjust the braking force according to the speed. No matter whether the motor vehicle is heavy or lightly loaded, it can only brake according to one braking force, so there is a braking current. The hidden danger of transistor burnout caused by too large, requires the use of transistors with stronger current capabilities, which indirectly increases the cost. Contents of the invention [0003] The application provides an adaptive braking method, a chip, a control devic...
