The invention relates to the technical field of automobile brake system development, in particular to a vehicle brake disc control method and device.The method comprises the steps that a current wheel speed pulse signal, a wheel cylinder pressure signal and an environment temperature signal of a vehicle are obtained; estimating the current temperature of the brake disc according to the current wheel speed pulse signal, the wheel cylinder pressure signal and the environment temperature signal; and the optimal braking force of the brake disc is matched according to the current temperature, and the brake disc is controlled to output the optimal braking force. Therefore, the problems that in the related technology, due to the fact that gravitational potential energy does work, the temperature of the brake disc rises, an energy conservation mode needs to peel off gravitational potential energy to do work, the applicability and reliability of brake disc control are reduced, and the accuracy of brake disc control is reduced are solved.
本申请涉及汽车制动系统开发技术领域,特别涉及一种车辆的制动盘控制方法及装置,其中,方法包括:获取车辆的当前轮速脉冲信号、轮缸压力信号和环境温度信号;根据当前轮速脉冲信号、轮缸压力信号和环境温度信号估算制动盘的当前温度;根据当前温度匹配制动盘的最优制动力,并控制制动盘输出最优制动力。由此,解决了相关技术中由于重力势能做功会导致制动盘温度升高,因此能量守恒方式需要剥离重力势能的做功,从而降低了制动盘控制的适用性和可靠性,并且降低了制动盘控制的精准性的问题。
