Description

The present invention relates to an outside world sensor that detects outside world information about an object existing around the own vehicle.

Recently, for example, an outside world sensor such as a radar ranging sensor detects outside world information about an object existing around the own vehicle, and based on the detected outside world information, autonomous driving control of the own vehicle including steering and acceleration / deceleration is performed. So-called self-driving cars that do so are widespread.

For example, Patent Document 1 describes a transmission / reception unit that transmits electromagnetic waves and receives reflected waves, a detection unit that detects the position of an object based on the reflected waves of electromagnetic waves from an object, and a transmission / reception surface and its own back surface of the transmission / reception unit. A cover member that covers the transmission / reception portion is provided so as to face each other, and the cover member is provided with a coating portion that covers the transmission / reception surface and below the coating portion, and is formed so as to project from the coating portion toward the surface side of the cover member. The invention of an in-vehicle radar device including at least a lower protruding portion is described.

According to the vehicle-mounted radar device (outside world sensor) according to Patent Document 1, the cover member includes at least a covering portion that covers the transmission / reception surface and a lower protruding portion formed so as to project from the covering portion toward the surface side of the cover member. Therefore, for example, it is possible to prevent water droplets that are rolled up from below due to the rotation of the wheels provided in the vehicle from adhering to the surface of the covering portion. As a result, it is possible to prevent the attenuation of electromagnetic waves and accurately detect the position of an object.

However, in an external sensor such as an in-vehicle radar device according to Patent Document 1, if a cover member having a covering portion covering the transmission / reception surface is provided, it is advantageous from the viewpoint of protecting the transmission / reception surface (detection surface), but the presence of the cover member is present. There is a problem that the accuracy of detecting the outside world is impaired.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an external world sensor capable of both protecting the detection surface and guaranteeing the external world detection accuracy.

In order to achieve the above object, an outside world sensor that detects outside world information about an object existing around the own vehicle, a sensor body having a detection surface for detecting the outside world information, and the sensor body of the own vehicle. The outside of the own vehicle has a sensor mounting bracket for mounting on the vehicle body and an opening facing the detection surface when viewed from the front so that at least a part of the external sensor overlaps with a portion other than the detection surface. A sensor garnish located on the side is provided, and the sensor body and the sensor garnish are attached to the rear part of the vehicle body via the sensor mounting bracket, and the sensor body and the sensor garnish are attached to the rear part of the vehicle body. In this state, the detection surface provided on the sensor body is directly exposed to the outside world on the outer side of the own vehicle through the opening provided in the sensor garnish, and the sensor garnish is the top portion of the detection surface. The most important feature of the sensor is that it is provided with a housing overhang that is located so as to project to the outside of the vehicle.
