Don’t Belief These 2 Automotive Options When It’s Raining

A sudden downpour can make visibility difficult while driving. But even heavy rain can impair the “view” of your vehicle’s security system and possibly put you in danger, as recent tests have shown.

According to an analysis by AAA, moderate to heavy rain can significantly reduce the performance of the vehicle security system. In closed course tests using simulated rainfall, AAA found the following:

  • Test vehicles with automatic emergency braking collided with a stopped vehicle in 33% of the cases at a speed of 56 km / h.
  • Test vehicles with lane departure warning left their lane in 69% of the cases.

AAA notes that vehicle safety systems are often evaluated under ideal operating conditions rather than using the real world conditions that drivers typically experience.

In a press release, Greg Brannon, Director of Automotive Engineering and Industry Relations at AAA says:

“Vehicle security systems rely on sensors and cameras to detect road markings, other cars, pedestrians and lane obstacles. Therefore, of course, they are more susceptible to environmental factors such as rain. “

In further testing, AAA found that a simulated dirty windshield covered with a concentration of insects, dirt and water did not adversely affect the overall performance of the safety system.

However, AAA notes that a dirty windshield can still affect the security system’s cameras, and the organization urges drivers to keep their windshields clean.

This is not the first time AAA has uncovered failures in vehicle safety systems. Previous tests showed that vehicles:

  • Have difficulty staying in lane in moderate traffic, on winding roads, and near busy intersections
  • In many situations, pedestrians cannot stop, even if people are crossing in front of a vehicle or a child jumps out between two parked vehicles
  • Start with disabled vehicles or drive too close to other vehicles or crash barriers

According to the AAA, such failures underscore the need for additional fine-tuning of the security systems. For now, AAA recommends drivers take the following steps:

  • Keep windshields clean
  • Avoid heavy braking and sharp turns
  • There is a five to six second gap to the vehicle in front
  • Accelerate – instead of stepping on the brakes – when the vehicle begins to aquaplane
