I can't believe huge charter busses do not come with ESP as standard equipment. ESP has saved my life on a few occasions. I will never buy another car without it.
As a bus driver myself, I am aware that try as you may to keep out of situations, sometimes the other idiots on the road put you on the spot. I would love to have that feature on my bus!!! And top skillz to the driver in the vid!
Es gracias a pruebas como ésta que grupo ADO ha decidido tener en sus flotillas de autobuses a este confiable Volvo 9700, es elegante, cómodo y sobre todo muy seguro, es otro mundo viajar en uno de estos.
Dear Luca and shiraq07It is correct that the coach without ESP was going faster, because the ESP-system slowed down the other coach (with this system engaged), enough to manage the turn without problems. It also ment that the driver could steer along the the track as planned. The other driver steered even more, but the front wheels lost their grip and the coach was sliding out.
Electronic Stability Program. Basically it controls the suspension. What it does is stiffen suspension up when more weight is forced from it and holds the vehicle upright without letting the body roll around. Most cars have it now. In day to day driving you won't probably notice it but in a emergency you will.
When cornering yes, its cause without ESP vehicle couldn't be controlled and was understeered. But they both entered the circle in same speed. The whole point of ESP is detecting and reducing loss of traction.
Yea, The 2nd test really demonstrated the technology good. But in the end, it depends on the driver making correct choices, but definitely these things aresafe now.
What's more impressive to me is the stability of even the non-ESP coach at 75km/hr. Wasn't there a Toyota SUV without ESP that actually rolled over under similar conditions?
+HaroOn Ops - Both coaches had the same initial speed, which the driver kept for the coach without ESP. The driver of the coach with ESP also kept the gaspedal in the same position, but the ESP-system took over and reduced the speed automatically, enough to maintain the course of the coach without risking turnover or drifting out. So you are correct in saying that the coach without ESP had a higher speed, but the test went exactly as planned thanks to the speed reduction from the ESP-system.
+MancoLepanto & Don - I can assure you that nothing is faked during the tests, I was there all the time. The ESP-system is connected to both the Engine speed and the brake system, thus reducing the speed of the coach together with individual wheel brake application in critical conditions. In the first test you can see this when the coach to the left dissapears out of the picture before the one on the right, as the ESP-system in the coach to the right has reduced the speed of the vehicle. The system takes over and the driver can not make the coach go any faster, even if he would push the gaspedal to the floor.For the second test, you can see my explanation below.
Bertil Forslund ok but, the turn with ESP-system is less violent, and that the "makes" the pilot. the drive with ESP-System on is less real Sorry my english and hello
+MancoLepanto & Don - It is correct that the turn with the ESP-coach is less violent, because the sytem takes over (not the driver) and reduces the speed of the coach to a safe situation, which allows the diver to clear the obstacles on the road. The drivers of the two coaches kept the gas pedal in the same position in both tests, so the coach without ESP continued in the same speed, which made it impossible for him to clear the obstacles. I can assure you, it is a fantastic system.
Clear winner for me: No ESP With ESP is plain out boring XD On the other hand you can CLEARLY see that the tests are rigged in favor of the ESP-equipped vehicle.
Pause at 2:25 and you will see that the bus with ESP is ahead of the bus without ESP. Pause at 2:26 and you will see that they reach the reference point at exactly the same time. The bus without ESP is clearly going much faster. Bad test
+Luca Fuoco - Both coaches had the same initial speed, which the driver kept for the coach without ESP. The driver of the coach with ESP also kept the gaspedal in the same position, but the ESP-system took over and reduced the speed automaticcaly, enough to maintain the course of the coach without risking turnover or drifting out. So you are correct in saying that the coach without ESP had a higher speed, but the test went exactly as planned thanks to the speed reduction from the ESP-system.
You are quite correct Luca. The ESP-system reduced the speed on the coach equipped with ESP, to enable a safe turn. The drivers were instructed to keep the same position of the throttle pedal during the whole turn. The driver of the coach without ESP tried to compensate for the drifting out by turning the front wheels more, but without success. I know this, because I supervised the tests. Bertil Forslund
LOL right about what, You provide no facts, and only anecdotal evidence, which is wrong in it's own right. Using each break individually and at the perfect moment, reacting far faster then you can. It never gets tired or distracted or confused. Traction Control can switch power from one wheel to another, instantly, can you do that? It is not the same as simply cutting power. Anti lock again reacts far faster, and while it cannot stop as fast as a perfect stop, you are not perfect.
