Problems solved by technology

[0004] At present, there are a lot of studies on the control strategy of electromechanical combined braking of wheeled vehicles. Most researchers focus on the distribution of electromechanical combined braking torque, while ignoring the problem of ground braking force saturation caused by the real-time adhesion coefficient of the road surface being too small. When the surface braking force is saturated, the vehicle is in an unstable braking state, and there are potential safety hazards when the vehicle is driving

Abstract

The invention provides a method and device for controlling the electromechanical combined braking of a tracked vehicle. The maximum braking torque on the ground is calculated; then a first braking torque calculated from the stroke of a brake pedal is obtained, and the maximum braking torque on the ground and the first braking torque are compared to determine whether ground adhesion is saturated ornot; a target braking torque is determined based on whether the ground adhesion is saturated or not; the total motor braking torque which two motors can provide at a current vehicle speed is calculated; the mechanical braking torque is calculated according to the target braking torque and the total motor braking torque; and based on the total motor braking torque and the mechanical braking torque, electromechanical combined braking control is performed on the tracked vehicle to ensure safety of entire vehicle braking.

Description

technical field [0001] The present invention relates to the technical field of tracked vehicle braking, and more specifically, to a control method and device for electromechanical combined braking of tracked vehicles. Background technique [0002] With the advancement of military technology and the improvement of standards, the army urgently needs a new type of land combat platform. Traditional fuel tracked vehicles are gradually encountering bottlenecks, and hybrid electric drive tracked vehicles are gradually being paid attention to because they can improve their mobility, economy, and protection. [0003] The dual-motor hybrid tracked vehicle is one of the important land combat platforms in my country. Compared with the traditional internal combustion engine powered tracked vehicle, the hybrid tracked vehicle can recover part of the braking energy in the form of regenerative braking when braking. Energy storage equipment has a good energy-saving effect and is of great sig...
