The invention relates to an intermediate shaft brake control method and device, computer equipment and a storage medium. A front auxiliary box gear, a target rotating speed difference, an oil temperature and an actual intermediate shaft rotating speed are obtained, and then theoretical valve opening time is obtained according to the target rotating speed difference, the oil temperature and a basic characteristic table; selecting a plurality of test valve opening times at fixed intervals according to the theoretical valve opening time, acquiring a plurality of brake resistance rotating speed differences according to the plurality of test valve opening times, the oil temperature and the basic characteristic table, and acquiring a plurality of system resistance rotating speed differences according to the plurality of test valve opening times, the oil temperature, the target rotating speed difference, the actual intermediate shaft rotating speed and the basic characteristic table; and finally, target valve opening time is obtained according to the multiple braking resistance rotating speed differences, the multiple system resistance rotating speed differences and the target rotating speed difference, an intermediate shaft brake is used for braking the intermediate shaft according to the target valve opening time, and therefore the rotating speed of the intermediate shaft is accurately controlled, and mutual collision between transmission gears is avoided.

    本申请涉及一种述中间轴制动器控制方法、装置、计算机设备及存储介质,通过获取前副箱挡位、目标转速差、油温、实际中间轴转速,然后根据目标转速差、油温以及基础特性表获取理论开阀时间,再根据理论开阀时间以固定间隔选取多个测试开阀时间,并根据多个测试开阀时间、油温以及基础特性表获取多个制动阻力转速差,再根据多个测试开阀时间、油温、目标转速差、实际中间轴转速以及基础特性表获取多个系统阻力转速差,最后根据多个制动阻力转速差、多个系统阻力转速差以及目标转速差获取目标开阀时间,并根据目标开阀时间使用中间轴制动器对中间轴进行制动,从而精确控制中间轴的转速,避免造成变速器齿轮间的相互碰撞。
