Crash simulations are used to investigate the safety of the car occupants during impacts on the front end structure of the car in a "head-on collision" or "frontal impact", the lateral structure of the car in a “side collision” or “side impact”, the rear end structure of a car in a "rear-end collision" or “rear impact”, and the roof structure of the car when it overturns during a ...
The g-force acting on an object under acceleration can be much greater than 1 g, for example, the dragster pictured at top right can exert a horizontal g-force of 5.3 when accelerating. The g-force acting on an object under acceleration may be downwards, for example when cresting a sharp hill on a roller coaster.
The Tesla Model S has an unusually low rollover risk of 5.7% due to its low center of mass. [ 8 ] [ 9 ] Light trucks will roll over at lateral accelerations of 0.8 to 1.2 g. Large commercial trucks will roll at lateral accelerations as low as 0.2 g [ 10 ] Trucks are more likely to roll over than passenger cars because they usually have taller ...
The Tesla Model S has a rate more than double than average, at 5.8 per billion vehicle miles driven; meanwhile, the Tesla Model Y — the best-selling vehicle in the world has a fatal crash rate ...
Small Overlap tests: this is where only a small portion of the car's structure strikes an object such as a pole or a tree, or if a car were to clip another car. This is the most demanding test because it loads the most force onto the structure of the car at any given speed. These are usually conducted at 15–20% of the front vehicle structure.
Microscopic traffic flow models are a class of scientific models of vehicular traffic dynamics.. In contrast, to macroscopic models, microscopic traffic flow models simulate single vehicle-driver units, so the dynamic variables of the models represent microscopic properties like the position and velocity of single vehicles.
Vehicle-to-vehicle communication is being developed in hopes that it will prevent more crashes and ease traffic congestion. Unfortunately the many potential benefits of vehicle-to-vehicle communication can only be achieved when all vehicles can communicate with one another. [10] Another technology in design is vehicle cyber security.
