no. 1 approach

[0069] Hereinafter, the vehicle washing system according to the first embodiment of the present invention will be described in detail with reference to the drawings. However, the embodiments shown below are described as examples for embodying the technical idea of ​​the present invention by taking a vehicle with an automatic driving system as an example, and are not intended to limit the present invention to the content shown in the embodiments. The present invention can be similarly applied to a vehicle cleaning system that does not include an automatic driving system, for example, a vehicle to be cleaned such as an optical sensor.

[0070] First, in order to understand the present invention, the level of automatic driving will be explained. According to the "SAEJ3016" established by SAE International (a non-profit organization in the United States with mobile experts as members), the classification of autonomous driving levels is as follows.

[0071] Level 0 (no driving automati...

[0216] Hereinafter, the second embodiment of the present invention will be described. In addition, parts with the same configuration as those of the first embodiment are denoted by the same reference numerals, and the description is omitted.

[0217] In the vehicle 210 equipped with the vehicle cleaning system 1, even if the driver is not aware of it, cleaning objects such as optical sensors will be cleaned. Therefore, the consumption of the cleaning fluid may exceed the driver’s awareness. Will be insufficient. In the second embodiment, a mechanism for notifying the driver of the remaining amount of the cleaning liquid based on the detection value of the liquid level sensor 13 provided on the cleaning liquid tank 12 is provided. As a result, the driver can always confirm the remaining amount of the cleaning fluid.

[0218] In addition, the vehicle 210 of the second embodiment includes a remaining amount display portion 235 that displays the cleaning liquid in the cleaning liquid...

Abstract

Provided is a cleaning system for a vehicle, provided with a plurality of cleaning units for cleaning objects to be cleaned including sensor surfaces of optical sensors installed in the vehicle, and acontrol unit capable of automatically controlling the cleaning units, wherein, if a cleaning request is issued with respect to the cleaning units, the control unit controls an order of priority for activating the cleaning units in accordance with a vehicle traveling state and / or an environmental state.

Description

Technical field [0001] The invention relates to a system for cleaning various cleaning objects installed on a vehicle. Background technique [0002] In recent years, the development of technologies for installing driving assistance systems on vehicles has continued to advance. In order to install a driving assistance system on a vehicle, various on-board sensors are required to detect the driving state of the vehicle. In these vehicle sensors, in addition to GPS, acceleration sensor, gyroscope sensor, temperature sensor, liquid level sensor, speed sensor, rotation speed sensor, driving distance sensor, driving operation detector and other sensors installed inside the vehicle body, it also includes : Radars such as millimeter wave radars that use radio waves to detect the state of the vehicle's surroundings; and optical sensors used to detect the driving state of the vehicle, driving lanes, signs, lane markings, other vehicles, or obstacles outside the vehicle. [0003] In additio...
