制動真空感測器的作用和工作原理

對於帶手動變速箱的車輛，制動真空感測器用於發動機啟動/停止自動裝置即使在發動機已關閉時，也必須確保制動助力。為此制動助力器配備了一個制動真空感測器。此制動真空感測器連接在發動機控制單元上。如果真空在某個定義的範圍之外，則執行一次發動機自動啟動，以便建立需要的真空

在制動真空感測器中，一個膜片將真空轉換成一個行程。這個行程由4個壓敏電阻轉換成電壓信號，然後發送到發動機控制單元。

制動真空感測器通過一個3芯插頭進行連接，制動真空感測器由發動機控制系統提供5V電壓和接地。制動真空感測器的信號只用於發動機啟動/停止自動裝置

Where is the brake vacuum sensor installed?

The brake vacuum sensor is plugged into the brake booster.

How the brake vacuum sensor works and how it works

For vehicles with a manual gearbox, the brake vacuum sensor is used for the engine start/stop automatic device which must ensure that the brakes are boosted even when the engine is switched off. For this purpose the brake booster is equipped with a brake vacuum sensor. This brake vacuum sensor is connected to the engine control unit. If the vacuum is outside a defined range, an automatic engine start is performed in order to establish the required vacuum

In the brake vacuum sensor, a diaphragm converts the vacuum into a stroke. This stroke is converted by 4 varistors into a voltage signal which is then sent to the engine control unit.

The brake vacuum sensor is connected via a 3-pronged plug and the brake vacuum sensor is supplied by the engine control system with a 5V voltage and earth. The signal from the brake vacuum sensor is only used for the engine start/stop automation
