Optoelectronic detection device with an adjustable bias voltage of a avalanche photo-detector for a motor vehicle, motor vehicle and corresponding method

摘要

The present invention relates to an optoelectronic detection device (7), in particular a laser scanner, for a motor vehicle, with an optical transmitter for the emission of electromagnetic radiation, with a avalanche photo-detector (10) for receiving at a target object in an environment of the motor vehicle reflected beams and for providing an electrical received signal (11) as a function of the received rays, having an evaluation device (12) for detecting the target object as a function of the electrical received signal (11), and with a control device (17), which is designed for this purpose, an electric bias voltage (bu) of the avalanche photo-detector (10) in the operation of the detection device (7), wherein said detecting means (7), a measuring device for detecting the value of a noise (r) of the electrical received signal (11) and the control device (17) is adapted to the bias voltage (bu) of the avalanche photo-detector (10) as a function of the value of the noise (r).
