A.B.S.
自动刹车
The automatic brake system (A.B.S.) pulses the brakes to avoid blocking the wheels and losing
control of the vehicle.
A first menu selects which one of the 6 parameters to modify.
Brake return: determines how much the brakes will be released at each pulse. 100% completely
releases the brakes and the servo returns to its neutral position at each pulse. 0% disables the
function.
Delay: if not 0%, inserts a delay between the ABS triggering and the activation of the brakes
pulses. 100% inserts a delay of around 2 seconds.
Cycle length: determines the length of a brake-release cycle. 20% is the shortest cycle length
(around 100ms) and 100% is the longest (around 500ms).
Trigger point: the ABS function is performed only if the brakes are applied over this threshold.
100% activates the ABS only at full brake.
Duty cycle: set the proportion of the time the brakes are applied and the time the brakes are
released. The lowest value (-4) releases the brakes only 10% of the time and the highest value
(+4) releases the brakes 90% of the time.
Steering mix: a positive value (N) will activate the ABS only if the steering
wheel is within the specified range around the neutral position. A negative
value (E) will activate the ABS only is the steering wheel is outside of that
same range around the neutral position.
Once a parameter is selected, a second dialog box allows to modify it.
The dark gray curve represents the ABS function at full brakes.
The red curve represents the actual ABS function.
The white line represents the trigger point beyond which the ABS
function is performed.
The bar graph at the bottom displays the channel 2 (throttle) in real time.
In this example, the duty cycle parameter is selected and is set to +2
mostly releasing the
brakes all the time. The brakes are applied at 43%, above the trigger
point set to 30%.
The activation of the ABS function can be assigned to a push button.
The ABS brake return can be assigned to a trim switch.
The ABS delay can be assigned to a trim switch.
The ABS cycle length can be assigned to a trim switch.
The ABS trigger point can be assigned to a trim switch.
The ABS brake return can be assigned to a trim switch.
The ABS duty cycle can be assigned to a trim switch.
自动刹车系统用脉冲刹车以避免车轮受阻或者车辆失控。
第一个菜单的六个参数中选择需要修改的参数
松刹车：设置一次脉冲刹车中刹车的比例。100%表示在每次脉冲
刹车中完全刹车同时舵机回到中位。0%则表示没有自动刹车功能。
延时：若不是0%，则会在自动刹车触发点和激活刹车脉冲之间嵌入
一个延迟，若为100%，则嵌入的延时大约为2秒。
周期：设置松刹车周期时间。最短的周期时间是20%（大概100毫
秒），最长的周期时间是100%（大概500毫秒）。
触发点：如果刹车超出了触发点，自动刹车功能将启用。如果触发
点为100%，则全刹车状态下自动刹车功能开启。
工作周期：设置刹车应用时间和松刹车时间的比例。最低值（-4）
时，松刹车只用10%的时间，最高值（+4）时，松刹车则用90%的时间。
方向混控：如果方向盘在中位附近指定范围内，数值（中）将会激活
自动刹车功能。如果方向盘超出中位附近指定范围内，数值（外）将会
激活自动刹车功能。一旦选定一个参数，可在第二个对话框内修改此参数。
深灰色曲线代表自动刹车功能在全刹车状态。
红色曲线代表实际的自动刹车功能状态。
白色的线代表触发点超出该线，自动刹车功能启动。
底部的条线图代表2通道（油门）的即时状态。
如图所示：选择工作周期参数，并将松刹车（大部分时间为松刹车）
设置到+2。刹车在43%的力度，超出触发点。触发点设置到30%。
激活自动刹车功能可分配给一个按键来控制。
自动刹车松刹车功能可分配给一个微调开关来控制。
自动刹车延时功能可分配给一个微调开关来控制。
自动刹车周期功能可分配给一个微调开关来控制。
自动刹车触发点功能可分配给一个微调开关来控制。
自动刹车工作周期可分配给一个微调开关来控制。
