With CAVA Wiper, the user can simulate the geometry of a wiper system to determine the wiped area on the windshield. Used together with the Field of View feature in CAVA Vision, it is possible to check the percentage of wiped area within the field of view. In addition the tool can calculate and visualize the key parameters important for the quality of the wiping operation.

Why Choose CAVA Wiper?

Optimize Wiped Area
  • Calculate the wiped area on the windshield based on the defining axis of the kinematic system
  • Flexibly define a wiper system with up to 3 wipers for front and rear
  • Supports the commonly used types of wiper kinematics
Fullfill Legal Requirements of Wiped Area on the Windshield
  • Check the legal requirements for wiped area on the windshield
  • Directly use the result of CAVA Vision 'fields of view' analysis as input for the analysis
  • Easily switch between different standard for different regions (UNECE and FMVSS)
Optimize Quality of Wiping Operation
  • Measure and visualize the key quality parameters
  • Visualize values as a color map on the windshield or as a 2D graph of curves
  • Quickly observe the effects of design optimization
  • Flexible reporting mechanism to create excel or text reports of calculated parameters

Key Features of CAVA Wiper

Wiper Kinematics

  • Define a wiper system with up to 3 wipers.
  • Supports three wiper types: Standard, Parallel and trapezoid.
  • Use any wiper arrangement: bottom/top mounted, clockwise/anti-clockwise rotation, butterfly, front and rear.
  • Calculate the wiped area on the windshield.
  • Use the CAVA Vision ‘fields of view’ feature to check fulfillment of legal requirements acc. UNECE-R 43 or FMVSS 104 on the wiped area.
  • Auto-detect valid rotation angle range for a given blade size.

Wiping Quality

  • Assess key quality parameters of the result of the wiping operation:
    – Curvature Radius of the blade on the windshield.
    – Normal deviation between blade and windshield (attack angle).
    – Folding angle and folding distance (rise and fall).
    – Sag value (bending of the blade).

  • Display calculated values as color map or vector feedback on the windshield.
  • Display as curve diagram for values along the blade for given angle.
