Overview

Active collision warning for manned forklift trucks

The Backup Assistance System (BAS) minimizes the risk of collisions for manned forklift trucks. It monitors areas of the vehicle which are obstructed from view of the driver. The BAS gives real-time feedback via visual and audible warnings when the forklift truck comes near a stationary or moving object. The compact system is based on a TiM3xx 2D LiDAR sensor that is engaged only when the forklift truck is in reverse, thereby eliminating false alarms when moving forward. The monitored area can be scaled up by adding an additional sensor.

Advantages

Need-based environment perception

The BAS driver assistance system is based on one or two TiM3xx 2D LiDAR sensors. Each of the sensors features a field of view of 270°. Due to flexible mounting options on the vehicle, your monitored area can be adapted and scaled according to the object detection requirements.

Compared to alternative solutions, the BAS detects both stationary and moving objects.

Detection of stationary and moving objects

**Use of precise LiDAR technology**
The 2D LiDAR based system actively detects obstacles in the path and clearly warns drivers and pedestrians. Unlike tag solutions, no additional sender and receiver cabling is required on the surrounding terrain. Compared to systems based on radar technology, the monitored area for collision warning can be defined more precisely with the BAS, which reduces false alarms.

Scalable monitored area

One sensor alone reliably detects objects behind the manned forklift truck.

A system variant with two sensors is well suited for targeted coverage of blind spots.

The use of two sensors is also recommended in environments with complex travel paths in order to provide optimal protection for lateral areas.

The scalable monitored area enables reliable object detection, thus preventing collisions. This contributes to smooth in-house storage, handling and transport processes in logistics

Three-stage warning concept

The BAS is equipped with a multi-level warning concept consisting of customizable warning fields and a signal light bar that warns the driver of potential collisions with visual and acoustic alarms. The integrated 2D LiDAR sensors only switches to active monitoring when the manned forklift truck is in reverse, preventing false alarms during forward travel.

Actively warns the driver with acoustic and visual warning signals

The monitored area is divided into monitoring fields – warning field 1 and warning field 2. The warning fields can be used to monitor various individually adjustable minimum distances to an object.

The signal light bar supports the driver with visual alarms. Green means clear travel path. If an object is detected in warning field 1, the color changes to yellow; if it enters warning field 2, it changes to red. Depending on the monitored area, the lamp emits additional acoustic warning signals via an integrated up to 98 dB buzzer.

Assistance for the driver with active alerts in real time without false alarms

Compact stand-alone system

All components of the Backup Assistance System are selected to keep integration time minimal so the vehicle is quickly ready for use again. Included with delivery: Sensors, signal light bars and mounting systems for all parts and connecting cables.

Cost-effective retrofitting

Compatible with different supply voltages, the system solution can be retrofitted to a wide range of vehicles, regardless of manufacturer or year of vehicle.

To make integration into the vehicle easy and installation as quick as possible, there is only one interface to the system – the control unit regulates the voltage supply and switching.

As a result of the low current consumption by the system, the power consumption from the vehicle battery is reduced. Saving charging time and therefore money.
