1. A time-of-flight sensor device for a motor vehicle comprising a light source and a detection device, wherein the detection device is formed with an array of optical pixels, wherein the light source and the detection device are coupled to a control and evaluation device, which activates the light source to emit light pulses and activates the detection device for detecting the light reflected back by the environment, as well as evaluating the detected signals of the detection device, wherein the control and evaluation device carries out a temporally coordinated illumination of a monitored space and an associated switching of the detection device into a detection mode for detection in a first spatial direction, wherein the array of optical pixels is switched on and off in reaction to the pulses such that an integration window of the individual pixels is temporally synchronized with the light source, such that spatially assignable distance data are detected, wherein the light source and the detection device are disposed in a receiving space, which is designed for the installation of the sensor device on a vehicle, wherein the receiving space is arranged along a bearing surface of the vehicle, wherein the light source is disposed inside the receiving space in a tilted manner, such that an angle of at least 5°

  • is formed between a normal to the bearing surface and an optical axis of the light source.
