摘要:
A raindrop detecting apparatus has a temperature sensor, an EEPROM, a processor and a raindrop sensor. A temperature characteristic data is defined by a first temperature data of the temperature sensor and a first output data of the raindrop sensor produced at a first temperature condition, and stored in the EEPROM. The processor updates a raindrop detection threshold by using the stored characteristic data, a second temperature data and a second output data produced at a second temperature, when an engine is started under no-raindrop condition. The processor compares an output data of the raindrop sensor with the raindrop detection threshold to detect a raindrop, while converting at least one of the characteristic data and the output data in correspondence with a temperature data produced at a raindrop detection time.

A raindrop detection device includes a first fixing member which is fixed to a windshield and has a first engagement portion, an inner housing in which a detection unit is accommodated, an outer housing in which the inner housing is accommodated and which is fixed to the inner housing, a second fixing member having a second engagement portion which is detachably engaged with the first engagement portion of the first fixing member, and a leaf spring which is engaged with the inner housing to press and bias the inner housing toward the windshield. The second fixing member has a leaf-spring biasing portion, which contacts the leaf spring to elastically bias the leaf spring toward the windshield at a predetermined pressing force.

A wiper control device for a vehicle with a wiper includes a day/night detecting device for detecting whether the vehicle is in day-like or night-like conditions. The device also includes a moisture detection device that detects a quantity of moisture on the vehicle and a controlling device that controls the wiping action of the wiper based on a wiping sensitivity to the quantity of moisture detected. The controlling device adjusts the wiping sensitivity between night-like wiping sensitivity and day-like wiping sensitivity. The controlling device adjusts wiping sensitivity to night-like wiping sensitivity when the day/night detecting device detects night-like conditions and to day-like wiping sensitivity when the day/night detecting device detects day-like conditions. Additionally, when the day/night detecting device detects a change between day-like and night-like conditions, the controlling device delays switching between night-like and day-like wiping sensitivity for a predetermined delay time.

A raindrop detection apparatus includes a light emitting unit for emitting light to an inner side of a windshield, a light receiving unit for receiving the light reflected by an outer surface of the windshield, a first lens unit which is arranged between the windshield and the light emitting unit to convert the light from the light emitting unit into parallel light, and a second lens unit which is arranged between the windshield and the light receiving unit to converge the reflected light at the light receiving unit. The second lens unit is larger than a radial cross section of the reflected light. An amount of raindrop landed on the outer surface of the windshield is detected based on an intensity of the light received by the light receiving unit.

A vehicle presence notification apparatus may include a dynamic speaker for radiating a notification sound from a vehicle in an audible frequency, and a sound pressure supplement unit is provided to control a sound pressure of the notification sound. The apparatus may further include a parametric speaker for generating a supersonic sound of the notification sound from a supersonic sound generation unit. The supersonic sound is emitted from a sound emission opening. The parametric speaker may further include a reflected sound pressure detecting unit for detecting a sound pressure generated by a reflection of the supersonic sound from the sound emission opening. The sound pressure supplement unit increases the sound pressure of the notification sound radiated by the dynamic speaker based on the sound pressure detected by the reflected sound pressure detecting unit.

A raindrop detecting device for detecting a raindrop amount on a windshield of a vehicle and selecting a wiping mode of a wiper based on the detected raindrop amount includes a controller for lowering the wiping mode when the detected raindrop amount is kept to be smaller than a mode-keep threshold while the wiper performs a predetermined number of wiping operations. The controller changes the predetermined number of wiping operations based on at least one of a sensitivity data of a user of the vehicle and a rainfall block data relative to the vehicle.
摘要:
A raindrop sensor includes a light-emitting element, a light-receiving element and a light guide body. The light-emitting element and the light-receiving element face a transparent panel. The light guide body, which is mounted on the transparent panel, includes an input lens, an input side dividing surface, an output lens and an output side dividing surface. The input lens collimates light emitted by the light-emitting element to form an input side collimated light beam. The output lens receives the collimated light beam, which is collimated by the input lens and is reflected by a reference surface of the transparent panel, to which the raindrop attaches. The output lens converges the reflected collimated light beam toward the light-receiving element. An intersection between an imaginary extension of the input side dividing surface and an imaginary extension of the output side dividing surface is located on the reference surface of the transparent panel.
