Abstract

A dump truck with an obstacle detection mechanism capable of detecting an obstacle around a vehicle using a plurality of radars provided on peripheral of the vehicle, the dump truck includes radars arranged with respect to a vehicle center plane in a backside of a rear axle case and between joints of rear suspension cylinders on the rear axle case, wherein the radars are arranged such that irradiation center axes in a vertical direction have a predetermined angle of dip to detect an obstacle in a backside of the vehicle.

Claims

1. A dump truck with an obstacle detection mechanism capable of detecting an obstacle around a vehicle using a plurality of radars provided on peripheral of the vehicle, the dump truck comprising

radars arranged with respect to a vehicle center plane in a backside of a rear axle case and between joints of rear suspension cylinders on the rear axle case, wherein the radars are arranged such that irradiation center axes in a vertical direction have a predetermined angle of dip to detect an obstacle in a backside of the vehicle.

2. The dump truck according to claim 1, wherein the radar comprising a pair of radars arranged laterally symmetrical to a center plane of the rear axle case, and the irradiation center axes irradiated from the pair of radars cross at the vehicle center plane.

3. The dump truck according to claim 2, wherein each of the plurality of radars including the pair of radars is surrounded by a protection member protecting the radar around an attachment position of the radar.

4. The dump truck according to claim 3, wherein the protection member has a cover through which an irradiated signal transmits in a forward direction of an irradiation direction.

5. A method of obstacle detection in a dump truck with an obstacle detection mechanism capable of detecting an obstacle around a vehicle using a plurality of radars provided to peripheral of the vehicle, the method comprising:

deleting obstacle information within a preset vehicle area indicating the vehicle from obstacle information detected by radars arranged in a backside of a rear axle case and between joints of rear suspension cylinders on the rear axle case and arranged such that irradiation center axes in a vertical direction have a predetermined angle of dip to detect an obstacle in a backside of the vehicle.
