主動防撞輔助含路口車流辨識、行人偵測及車道壅塞防撞輔助 Active Brake Assist with cross-traffic function

Function of Active Brake Assist with cross-traffic function

Active Brake Assist with cross-traffic function consists of:

Distance warning function
Autonomous braking function
Situation-dependent braking assistance
Evasive Steering Assist

Active Brake Assist with cross-traffic function can help you to minimise the risk of a collision with vehicles or pedestrians, or reduce the effects of such a collision.

If Active Brake Assist with cross-traffic function detects that there is a risk of a collision, you will be warned visually and acoustically.

If you do not react to the visual or acoustic warning, autonomous braking can be initiated in critical situations.

In particularly critical situations, Active Brake Assist with cross-traffic function can initiate autonomous braking directly. In this case, the visual and acoustic warning occurs simultaneously with the braking application.

If you apply the brake yourself in a critical situation or apply the brake during autonomous braking, situation-dependent braking assistance occurs. This increases the brake pressure up to maximum full-stop braking if necessary.

If the autonomous braking function or the situation-dependent braking assistance is triggered, additional preventive measures for occupant protection (PRE-SAFE®) may also be initiated, if the vehicle is equipped with these.

WARNING

Risk of an accident if the detection of Active Brake Assist with cross-traffic function is impaired

Active Brake Assist with cross-traffic function cannot always recognise objects or complex traffic situations clearly.

In such cases, Active Brake Assist with cross-traffic function can:

Give a warning or brake without reason

Not give a warning or not brake

Always pay careful attention to the traffic situation and do not rely entirely on Active Brake Assist with cross-traffic function.

Be prepared to brake or swerve if necessary.

Also observe the system limits of Active Brake Assist with cross-traffic function.

The individual subfunctions are available in the following speed ranges:

Distance warning function

The distance warning function issues a warning at speeds:

From approximately 18 mph (30 km/h), if over several seconds the distance maintained to the vehicle travelling in front is insufficient for the driven speed. The distance warning lamp then lights up in the instrument cluster.
From approximately 4 mph (7 km/h), if your vehicle is critically close to a vehicle or pedestrian. An intermittent warning tone will then sound and the distance warning lamp will light up in the instrument cluster.

Brake immediately or take evasive action, provided it is safe to do so.

The distance warning function can aid you in the following situations with an intermittent warning tone and a warning lamp:

Speeds up to approximately 155 mph (250 km/h) when approaching vehicles ahead.
Speeds up to approximately 62 mph (100 km/h) when approaching stationary vehicles.
Speeds up to approximately 43 mph (70 km/h) when approaching pedestrians who are standing still or crossing, or crossing vehicles.

Autonomous braking function

If the vehicle is travelling at speeds above approximately 4 mph (7 km/h), the autonomous braking function may intervene in the following situations:

Speeds up to approximately 155 mph (250 km/h) when approaching vehicles ahead.
Speeds up to approximately 62 mph (100 km/h) when approaching stationary vehicles.
Speeds up to approximately 43 mph (70 km/h) when approaching pedestrians who are standing still or crossing, or crossing vehicles.

Situation-dependent braking assistance

The situation-dependent braking assistance can intervene from a speed of approximately 4 mph (7 km/h) in the following situations:

Speeds up to approximately 155 mph (250 km/h) when approaching vehicles ahead.
Speeds up to approximately 62 mph (100 km/h) when approaching stationary obstacles.
Speeds up to approximately 43 mph (70 km/h) when approaching pedestrians who are standing still or crossing, or crossing vehicles.

Cancelling a brake application initiated by Active Brake Assist with cross-traffic function

You can stop a brake application initiated by Active Brake Assist with cross-traffic function at any time by:

Depressing the accelerator pedal fully.
Releasing the brake pedal.

If at least one of the following conditions is fulfilled, Active Brake Assist with cross-traffic function will cancel the intervention:

You manoeuvre to avoid the obstacle.
There is no longer a risk of collision.
An obstacle is no longer detected in front of your vehicle.

Evasive Steering Assist

Evasive Steering Assist has the following characteristics:

Can detect stationary or crossing pedestrians.
Can assist the driver with additional steering assistance if it detects a swerving manoeuvre.
Can be activated by an abrupt steering movement during a swerving manoeuvre.
Can assist during swerving and straightening of the vehicle.
Can react from a speed of approximately 12 mph (20 km/h) up to a speed of approximately 43 mph (70 km/h).
You can prevent the assistance at any time by active steering.

WARNING

Risk of an accident despite Evasive Steering Assist

Evasive Steering Assist cannot always clearly identify objects and complex traffic situations.

In addition, the steering support of Evasive Steering Assist is generally not sufficient to avoid a collision.

In such cases Evasive Steering Assist can:

give an unnecessary warning or provide assistance

not give a warning or not provide assistance

Always pay careful attention to the traffic situation; do not rely on Evasive Steering Assist alone.

Be ready to brake and take evasive action, if necessary.

Prevent the assistance by actively steering in non-critical driving situations.

Drive at an appropriate speed if pedestrians are close to the path of your vehicle.

Also observe the system limits of Evasive Steering Assist.

System limits

Active Brake Assist with cross-traffic function may be impaired or may not function in the following situations:

In snow, rain, fog, heavy spray, if there is glare, in direct sunlight or in greatly varying light conditions.
If the sensors are dirty, misted up, damaged or covered.
If the sensors malfunction due to other radar source interference, for example strong radar reflections in multi-storey car parks.
If a loss of tyre pressure or a defective tyre has been detected and displayed.

The system may not react correctly:

In complex traffic stations where objects cannot always be clearly identified.
To pedestrians or vehicles if they move quickly into the sensor detection range.
To pedestrians who are hidden by other objects.
If the typical outline of a pedestrian cannot be distinguished from the background.
If a pedestrian is not recognised as such, e.g. due to special clothing or other objects.
On bends with a tight radius.

具有十字路口交通功能的主動煞車輔助功能

具有十字路口功能的主動煞車輔助系統包括：

距離警告功能
主動煞車功能
視情況而定的煞車輔助
閃避轉向輔助

具有十字路口功能的主動煞車輔助系統可以幫助您將與車輛或行人碰撞的風險降至最低，或減少此類碰撞的影響。

如果具有十字路口功能的主動煞車輔助系統偵測到存在碰撞風險，您將收到視覺和聽覺警告。

如果您對視覺或聽覺警告沒有反應，則可以在危急情況下啟動主動煞車。

在特別危急的情況下，具有十字路口功能的主動煞車輔助系統可以直接啟動主動煞車。在這種情況下，視覺和聽覺警告與煞車應用同時發生。

如果您在危急情況下自行煞車或在主動煞車期間應用煞車，則會出現視情況而定的煞車輔助。如有必要，這會將煞車壓力增加到最大完全停止煞車。

如果主動煞車功能或視情況而定的煞車輔助被觸發，則還可以啟動額外的乘員保護預防措施 (PRE-SAFE®)，前提是車輛配備了這些措施。

警告

如果具有十字路口交通功能的主動煞車輔助系統的偵測受損，則有發生事故的風險

具有十字路口功能的主動煞車輔助系統無法始終清晰的識別物體或複雜的交通情況。

在這種情況下，具有十字路口交通功能的主動煞車輔助系統可以：

無需理由直接發出警告或剎車

不發出警告或不剎車

始終注意交通情況，不要完全依賴具有十字路口交通功能的主動煞車輔助系統。

如有必要，準備煞車或轉向。

還要注意具有十字路口交通功能的主動煞車輔助系統的系統限制。

各個子功能在以下速度範圍內可用：

距離警告功能

距離警告功能在以下速度時發出警告：

從大約 18 英里/小時（30 公里/小時）開始，如果超過幾秒鐘，與前面行駛的車輛保持的距離不足以滿足行駛速度。然後儀錶盤中的距離警告燈亮起。
從大約 4 英里/小時（7 公里/小時）起，如果您的車輛非常靠近車輛或行人。然後會發出間歇性警告音，並且儀錶盤中的距離警告燈將亮起。

立即煞車或採取閃避措施，前提是這樣做是安全的。

距離警告功能可以在以下情況下透過間歇性警告音和警告燈幫助您：

接近前方車輛時，速度最高可達約 155 英里/小時（250 公里/小時）。
接近靜止車輛時，速度最高可達約 62 英里/小時（100 公里/小時）。
接近靜止不動、橫向穿越或橫向穿越車輛的行人時，速度可高達約 43 英里/小時（70 公里/小時）。

主動煞車功能

如果車輛以大約 4 英里/小時（7 公里/小時）以上的速度行駛，主動煞車功能可能會在以下情況下進行介入：

接近前方車輛時，速度最高可達約 155 英里/小時（250 公里/小時）。
接近靜止車輛時，速度最高可達約 62 英里/小時（100 公里/小時）。
接近靜止不動、橫向穿越或橫向穿越車輛的行人時，速度可高達約 43 英里/小時（70 公里/小時）。

視情況而定的煞車輔助

在以下情況下，視情況而定的煞車輔助系統可以從大約 4 英里/小時（7 公里/小時）的速度開始介入：

接近前方車輛時，速度最高可達約 155 英里/小時（250 公里/小時）。
接近靜止障礙物時，速度可達約 62 英里/小時（100 公里/小時）。
接近靜止不動、橫向穿越或橫向穿越車輛的行人時，速度可高達約 43 英里/小時（70 公里/小時）。

取消十字路口交通的主動煞車輔助系統啟動的煞車功能

您可以透過以下方式隨時停止十字路口功能的主動煞車輔助系統啟動的煞車功能：

完全踩下加速踏板。
鬆開煞車踏板。

如果至少滿足以下條件之一，十字路口交通功能的主動煞車輔助系統將取消介入：

您操縱以避開障礙物。
不再有碰撞的危險。
不再偵測到車輛前方的障礙物。

閃避轉向輔助

閃避轉向輔助具有以下特點：

可以偵測靜止或十字路口的行人。
如果偵測到轉彎操作，可以透過額外的轉向輔助為駕駛者提供幫助。
可以在轉彎操作期間透過突然的轉向動作啟動。
可以在車輛轉彎和修正過程中提供幫助。
可以從大約 12 英里/小時（20 公里/小時）的速度到大約 43 英里/小時（70 公里/小時）的速度做出反應。
您可以隨時透過主動轉向來取消輔助。

警告

儘管有轉向輔助系統，但仍有發生事故的風險

閃避轉向輔助不能總是清楚的識別物體和複雜的交通情況。

此外，閃避轉向輔助的轉向輔助通常不足以避免碰撞。

在這種情況下，閃避轉向輔助將會：

給予不必要的警告或提供協助

不發出警告或不提供協助

隨時注意交通情況；不要單獨依賴規避轉向輔助。

準備好煞車並在必要時採取規避措施。

在非緊急情況下主動轉向來阻止轉向輔助。

如果行人靠近您車輛的行駛路徑，請以適當的速度行駛。
