The capability of Sentient’s Vehicle Motion Control exceeds the ability of human drivers. To achieve this, the angular speed of the steering wheel need to be greater than 1500 °/s. Using a car with a steering wheel moving that fast would be unsafe, e.g. sticking a finger into the wheel could lead to bone fractures.
Also, in Autonomous Vehicle Motion Control, you would prefer to keep the steering wheel still to avoid any annoying motions.
Sentient’s steer-by-wire has the unique combination of disturbance rejection and premium steering feel and it has been in production since 2013.
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.
If true autonomous driving is to be a reality the car has to be sentient – it has to be able to perceive and feel critical situations as well as avoid occurrence of accidents by e.g. evasive manoeuvres.
Autonomous vehicles, such as Tesla aren’t sentient, rolling androids – yet!
Have you experienced something similar to this? Think of a situation with a normal car of today and quite bad weather. Assume that you are an experienced driver, and that the others in your company is not. You will offer to drive and everybody, including you, will be happy about it. Continue reading
This is analogous to a future with autonomous vehicles. Skilled drivers will not be able work or sleep in the car if the vehicle itself isn’t at least in parity with the skill of his own.
U.S. Transportation Secretary Elaine Chao called on Silicon Valley to “step up” and explain self-driving technology to help the public overcome its fears of robots taking the wheel.
Chao points at a critical fact. Unless someone explain, the market will not understand that autonomous driving require higher safety standard once self-driving cars are introduced. And as we know it, traditional technology development will be a slow movement toward safer vehicles.
It’s obvious that the market eventually will require active safety and vehicle control functionality in parity with very skilled drivers, such as journalists or test drivers. It is our obligation to make sure that the vehicle fleet produced will be in parity with experienced drivers. What is your opinion?
We noise about reasonable customer requirements and we provide the market with solutions to such requirements..
Have you seen the manoeuvre in our latest film The Lane Change, Episode II? The manoeuvre was done by a predefined path including a 360 degrees power-sliding pirouette. Continue reading
With the manoeuvre, we want to show that we can control the car under extreme conditions and more importantly – follow the predefined path fully autonomous. This is possible with an integrated brake and steering control and it means that the car can evade objects on or near the road more efficiently than with conventional control.
