一種電子式真空煞車助力系統，適用於一電動車，該電動車包括一真空管單元，該電子式真空煞車助力系統包含一煞車單元、一真空泵單元、一電子式壓力感測單元、一電子控制單元，及一故障顯示單元。該真空泵單元包括一電動真空泵。該電子式壓力感測單元用以偵測該真空管單元內的真空度。該電子控制單元包括一電壓感測器、一電流感測器，及一主控制器，該主控制器分別於不同的失效防護模式及不同的系統作動模式間切換。該故障顯示單元用以顯示故障訊息，可主動偵測並即時提供故障訊息，具有精確壓力控制及失效偵測防護的功效。

An electric brake assist system is adapted for use with a vehicle, and includes a vacuum pump unit including an electric vacuum pump connected to the vacuum tube unit, an electric pressure sensing unit for detecting a vacuum degree in a vacuum tube unit of the vehicle, and an electric control unit to sense an electrical parameter associated with operation of the vehicle and the brake assist system. The electric control unit includes a controller configured to operate in at least one of a plurality of failure protection modes and system operation modes according to the detected vacuum degree and the sensed electrical parameter.
