What is emergency steering assist?

It is not yet possible to use fully automated cars, but there is already a great technology that helps the driver enjoying more confident driving. Thanks to Emergency Steering Assist (ESA) technology the driver will get the support in any case of emergency. The newest emergency steering assist system works by applying extra steering torque during performing an evasive maneuver. This will guide the car along the best possible line and help you to avoid a collision. Collisions not only put your health at risk but also cause damage to your car. Even if you know a great repair place like Dallas Body Shop, it’s still going to be a hassle, cost you money, and your car is likely to be out of order for some time. Surely it’s worth investing in this new technology for these reasons alone?

ESA - emergency steering assist

According to Dr Carsten Hass, an engineering manager, ESA is the next step in collision avoidance. In the situation, when the driver swerves to avoid an obstacle, emergency steering assist system will calculate the best trajectory around it, and will apply additional TRW steering for the vehicle to follow the trajectory and stay stabilized.

It is still up to the driver to choose the maneuver. Thanks to the vehicle sensors the driver will be alerted to the hazard ahead. After this, they start to react giving their support to the driver.

This system has been tested by car journalists, vehicle manufacturers, and technology media this week at Germany’s Hockenheimring. One journalist says that emergency steering assist system gives the driver reassurance that the right corrections will be made. The driver still has the main control over the situation, but the help of emergency steering is really noticeable.

Hass said that the driver remains the main and the one to really control the situation. The one can simply override the system. ESA has been designed to help the driver to react more accurately faster.

ESA has data from TRW’s video camera as well as radar sensors. This is needed for providing an accurate image of the road ahead, with an interface to electric steering system.

Various TRW steering systems were developed along with researchers from the Technical University of Dortmund. This technology will be available for production in 2017.
