In an oversteer situation, ESP works well in stabilizing the vehicle, but not with very high precision in the vehicle position. S+ Oversteer Control considerably reduces the instability as well as the risk of ending up outside the lane. S+ Oversteer Control increases the vehicle safety and has already started to save lives.
Watch the difference in vehicle position between standard ESP and S+ Oversteer Control.
According to the US Department of Transportation and NHTSA’s publication (https://www.nhtsa.gov/sites/nhtsa.dot.gov/files/documents/13069a-ads2.0_090617_v9a_tag.pdf) an Autonomous Driving System (ADS) is responsible for performing Object and Event Detection and Response. This refers, on one hand, to the detection of any circumstance that is relevant to the immediate driving task, and on the other hand, implementation of the appropriate driver or system response to such circumstance.
When shifting to autonomous driving we have an opportunity to make car transportation safer from day one, which we know wasn’t the case for manually driven cars. The appropriate system response in a critical situation, such as skidding on icy roads, should and can result in a behavior that is far more safe than advanced driving in traditional cars with ESP. Why not just do it?
Watch our film demonstrating the difference between Vehicle Motion Control and ESP in an autonomous car.
Today, autonomous driving is about to become more dangerous on the roads than traditional vehicles handled by experienced drivers. We claim that neither skilled drivers nor the general public shall accept that autonomous driving is less safe than today’s cars driven by experienced drivers, and we have the solution.
In the hype of autonomous driving, very few speak about the critical situations every car, autonomous or not, will have to handle. A self-driving car will have to handle critical situations, such as aquaplaning and skidding on ice in high speed. This is an important aspect of safety that needs to be addressed in public. We are convinced that for introducing autonomous driving, driverless cars that controls critical situations in parity with very skilled drivers is a prerequisite.
It is a reasonable assumption that the market for self-driving cars will be defined by society as well as by experienced drivers, such as test drivers or vehicle journalists. The society will probably not accept that autonomous vehicles are more dangerous than today’s average vehicle fleet – at a minimum. Customers’ expectations will vary depending on their knowledge about the functionality of autonomous vehicles. The informed customer will, just as an experienced driver, not accept self-driving cars with less safety than a car with an experienced driver.
Sentient’s Vehicle Motion Control makes the average driver at least an expert driver, reducing the risk of accidents. Where traditional ESP prevents instabilities, Vehicle Motion Control prevents instabilities and follows the intended path.
This manoeuvre is possible with integrated brake and steering control.
Watch Sentient’s Autonomous Vehicle Motion Control perform a lane change in extreme winter condition.
Filmed in Arjeplog, Arctic Circle, Northern Sweden
