The invention discloses a wheel anti-lock braking system suitable for ramp braking. A wheel speed recognition module of the wheel anti-lock braking system is used for recognizing a wheel speed signal and a wheel acceleration signal of a vehicle; the vehicle speed acquisition module is used for calculating vehicle body speed signals; the driving intention recognition module is used for obtaining front and rear axle enabling flag bits; the state machine module is used for judging whether the working state of the low-speed ramp anti-lock braking system is standby or closed, and when the working state of the low-speed ramp anti-lock braking system is closed, the conventional anti-lock braking system is started; the state machine module receives the front and rear shaft enabling flag bits and transmits the front and rear shaft enabling flag bits to the control logic module when the working state of the low-speed ramp anti-lock braking system is standby; and the control logic module is used for sending a low-speed ramp anti-lock braking system control instruction when the wheels have the locking tendency. According to the invention, the anti-lock control on the wheel at a low speed which cannot be achieved by a conventional wheel anti-lock braking system, especially during ramp braking, is realized.
本发明公开了适用于坡道制动的车轮防抱死系统,它的轮速识别模块用于识别车辆轮速信号和轮加速度信号;车速获取模块用于计算车身速度信号;驾驶意图识别模块用于得到前后轴使能标志位;状态机模块用于判断低速坡道防抱死制动系统的工作状态为待机或关闭,当低速坡道防抱死制动系统的工作状态为关闭时,启动常规防抱死制动系统;状态机模块接收前后轴使能标志位,并在低速坡道防抱死制动系统的工作状态为待机时,将前后轴使能标志位传输给控制逻辑模块;控制逻辑模块用于在车轮存在抱死趋势时发出低速坡道防抱死制动系统控制指令。本发明实现了常规车轮防抱死制动系统所不能达到的低速尤其是在坡道制动时对车轮进行的防抱死控制。
