| 摘要 |
The invention relates to a sensor device (2) for a motor vehicle (1). The sensor device has a light source (10) and a detection device (20), said detection device is formed using an array of optical pixels. The light source (10) and the detection device (20) are coupled to a control and evaluation device (30) which activates the light source (10) to emit light pulses and activates the detection device to carry out the detection process. The control and evaluation device (30), the detection device (20) and the light source (10) interact as a time-of-flight camera (ToF camera), allowing spatial range data to be detected. The control and evaluation device (30) has multiple activation schemes for different groups of pixels of the detection device (20), a first activation scheme (idle mode) activating and evaluating a portion of pixels as a first pixel group and a second activation scheme (active scheme) activating and evaluating a larger portion of pixels as a second pixel group. Depending on the results of the evaluation according to the first activation scheme, the control and evaluation device switches to an activation according to the second activation scheme. |
