| 摘要 |
The invention relates to a velocity detection apparatus in a motor vehicle, having a measuring head for detecting a movement, from which a corresponding measurement signal can be supplied to both an application control apparatus and a safety control apparatus. For this purpose, the measurement signal can be processed by the application control apparatus, and the processed data can be relayed to a control device. Furthermore, the measurement signal can be processed in the safety control apparatus, and the processed data can be encrypted in an encryption apparatus, and the encrypted data can be stored in a storage apparatus, and the storage contents of the storage unit can be relayed to the control device. The components of the velocity detection apparatus are enclosed by a housing (1), the integrity of which can be monitored by a protection apparatus. The protection apparatus is a housing opening sensor system arranged inside the housing (1) and the sensor system can be used to generate electrical manipulation information by opening the housing (1). |
