Methods and systems for estimating the appropriate brake disc temperature according to the vehicle's operating environment

Abstract

The invention relates to a method and system for estimating the appropriate brake disc temperature according to the vehicle's operating environment. The method described in the invention includes: establishing parameter groups for cooling brake disc temperatures caused by convection and conduction, each parameter group corresponding to a type of vehicle operating environment; establishing parameter groups for cooling brake disc temperatures caused by thermal radiation, each parameter group corresponding to a type of vehicle operating environment; Determine the current operating environment of the vehicle and the target parameters corresponding to that operating environment; calculate the brake disc temperature cooling value corresponding to the determined operating environment based on the target parameters; and estimate the brake disc temperature using the brake disc temperature cooling value corresponding to the determined operating environment.
