[0002] In the prior art, the device used for calibrating the vehicle’s autonomous driving environment perception sensor is a metal triangular cone and a tape measure. The calibration method is to place the metal triangular cone in front of the sensor to be calibrated on the target vehicle, and use the tape measure to measure the actual The position reference parameters of the metal triangular cone relative to the target vehicle sensor are based on the position reference parameters and the position perception parameters of the metal triangular cone relative to the target vehicle sensor sensed by the sensor to be calibrated, and the sensor to be calibrated is calibrated. This calibration method is slow. And the calibration accuracy is not high

Embodiment Construction
[0045] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.
[0046] In this disclosure, when an element is said to be "fixed to" another element, it can be directly on the other element, or one or more intervening elements may be present therebetween, unless stated to the contrary. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or one or more intervening elements may be present therebetween. The terms "vertical", "horizontal", "left", "right" and similar expressions are used in this specification for the purpose of description only.
[0047] Unless otherwise defined, all technical and scientific terms used in this specification have the same me...

The invention relates to a calibration device and methods for calibrating a vehicle sensor and a vehicle. The device comprises a detector, a reflecting part and a controller; the detector is used fortransmitting a first detection signal, receiving a first echo signal and determining a first position parameter of the detector relative to the sensor according to the two signal; the reflecting partis used for reflecting a second detection signal transmitted by the vehicle sensor to form a second echo signal, and the two signals are used for the vehicle sensor to determine a second position parameter of the vehicle sensor relative to the reflecting part; and the controller is used for determining a third position parameter of the reflecting part relative to the vehicle sensor according to the first position parameter and the relative positions of the detector and the reflecting part and sending the third position parameter to the vehicle. Accordingly, the vehicle can calibrate the vehicle sensor according to the third position parameter, determined by the calibration device, of the reflecting part relative to the vehicle sensor and the second position parameter, determined by the vehicle sensor, of the vehicle sensor relative to the reflecting part, therefore, the precision of the vehicle sensor is improved, and the calibration speed is high.
