Electric Vacuum Pump Control Unit

The Electric Vacuum Pump Control Unit (EVP*-ECU) provides safe and reliable control of the vacuum pump including driver warning in case of malfunction within the vacuum system and provides full diagnostic capability by integrated safety master slave controllers, evaluation of 1 or 2 vacuum sensor(s), power module with soft start capability and CAN bus communication. The EVP is able to cover all vacuum requirements especially in electric, hybrid and diesel-powered vehicles as well as in gasoline direct injected engines. The EVP is a basic component for CO2 reduction, as it serves as a flexible vacuum on demand source.    Furthermore, the EVP is used if the internal combustion engine on modern vehicles does not produce sufficient vacuum to operate the brake booster and vacuum-controlled actuators.
