LASER RADAR APPARATUS

摘要

A laser radar apparatus includes a beam projecting unit and a beam receiving unit that receives via a glass surface a reflective wave occurring when a beam projected from the beam projecting unit is reflected from an object. The laser radar apparatus further includes control unit that commands a prompt operation mode of a wiper when an amount of the objects is determined to be greater than or equal to a threshold level based on a beam reception level detected by the beam receiving unit, and a wiper operation control unit that controls the wiper to operate in the prompt operation mode after a waiting time period elapses. The waiting time period is from when it is detected that the amount of the objects is greater than or equal to the threshold level to when a wiper operation starts.

主权项

1. A laser radar apparatus comprising:
a beam projecting unit that projects a pulse-shaped beam to an outside of a vehicle from an inside of the vehicle via a glass surface; a beam receiving unit that is installed at a position separated from the beam projecting unit in a substantially horizontal direction, and receives via the glass surface a reflective wave occurring when the beam projected from the beam projecting unit is reflected from an object; a control unit that commands a prompt operation mode of a wiper which wipes the glass surface when an amount of the objects is determined to be greater than or equal to a given level based on a beam reception level detected by the beam receiving unit; and a wiper operation control unit that controls the wiper to operate in the prompt operation mode after a waiting time period elapses, the waiting time period being from when it is detected that the amount of the objects is greater than or equal to the given level to when a wiper operation starts.
