Embodiment Construction
[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.
[0023] According to whether it can be decoupled from the driver's input, the brake electronic control system can be divided into decoupled and non-decoupled. Most of the existing braking electronic control systems are non-decoupled structures. Therefore, when the COR module coordinates various functions, it must consider the feedback force of the braking electronic control system to the driver. As we all know, the brake anti-lock braking system ABS will have a spring foot phenomenon during the function process, wh...

The invention discloses a braking torque coordination method and device and a vehicle. The braking torque coordination method comprises the steps that a multi-stage braking torque adjusting framework of a braking electric control system is obtained; the braking torque adjusting framework comprises a first priority function, a second priority function and a third priority function; the output braking torque of the third priority function is obtained to serve as a first-layer output value; whether the second priority function outputs braking torque or not is judged; if yes, the output braking torque of the second priority function serves as a second-layer output value; if not, taking the first layer output value as a second layer output value; judging whether the first priority function has output braking torque or not; if yes, outputting the output braking torque of the first priority function as a target value; and if not, outputting the target value indicated by the second-layer output. According to the technical scheme, braking control which is simple in strategy and easy to adjust performance can be achieved.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a braking torque coordination method and device, and a vehicle. Background technique [0002] The braking torque coordination module COR is an important functional module of the braking electronic control system. The output of more than 10 sub-functions in the braking electronic control system is the target braking torque. The COR module is used to coordinate and evaluate which function output is currently the most suitable and can best ensure vehicle safety, so as to make a final decision. The target braking torque is given to the execution control module of the braking electronic control system to realize the control and execution of the target braking torque. [0003] In the past few decades, the braking electronic control system is non-decoupled. Therefore, the coordinated control of its COR needs to consider the coupling relationship between the driver's input force and fe...
