Do you love that sensation of suddenly being hurled forward when you have to abruptly slam on the brakes If youre in a self driving car, the effects apparently even more dramatic, researchers from the University of Michigan announced Thursday. People have a tendency to jolt forward as much as 8 inches when the vehicle abruptly slams on the brakes, according to the Detroit Free Press, and that amount of movement presents a number of implications for automakers developing automated technology like emergency braking.

May and June, and plopped them inside autonomous testing cars. Matthew Reed, a U of M research professor, told the Freep they recorded the acceleration and how people respond to a hard braking event. The Freep explains what they found They discovered that when passengers unexpectedly had the brakes slammed, they pitched forward as much 8 inches despite wearing a seat belt in the front passenger seat. Thats a significant amount of movement while being restrained and has implications as an increasing number of vehicles employ emergency braking and other types of self driving technology. Automatic braking systems tend to brake harder than you or I would, the Freep says.

So for passengers inside an autonomous car, especially if theyre not expecting it, that could cause them to dramatically pitch forward. The Freep goes on Reed said the research could be used to help design features that automatically adjust seat belts or send out a warning sound before the brakes are applied or before the vehicle maneuvers to avoid a crash. Its an interesting dynamic to consider as automakers are feverishly working to develop self driving cars and bring them to the market. A number of carmakers have staked out ambitious timelines to have autonomous cars that dont require human intervention on the road by next decade. The state of self driving cars on the road at the moment is we have some semi autonomous systemsRead more Read. Two things come to mind humans have already proved to be terrible at taking the wheel of semi autonomous cars when they require drivers to intervene and resume control. So I wonder if drivers would have enough time to respond to automatic seat belt tightening or warning signals, and be more prepared before the self driving car comes to a halt. Beyond that, cant you just have the brakes not be applied so hardI imagine that would take more finesse, where the technologys capable of assessing how close the car is and brake at a corresponding levelbut the research suggests its simply more about how humans react above all else.

A Word on guaranteed tyres. When I moved to America, I noticed a lot of car tyre shops offering tyres with x,0. Its not unusual to see 6. It amazed me that anyone would be foolish enough to put a guarantee on a consumable product given that the life of the tyre is entirely dependent on the suspension geometry of the car it is being used on, the style of driving, the types of road, and the weather.

Yet many manufacturers and dealers offer an unconditional guarantee. Theres the catch though. The after the word unconditional takes you elsewhere on their information flyer, to the conditions attached to the unconditional guarantee. If you want to claim on that guarantee, typically youll have to prove the tyres were inflated to the correct pressure all the time, prove they were rotated every 3. Wording in the guarantee will be similar to this used in normal service on the vehicle on which they were originally fitted and in accordance with the maintenance recommendations and safety warnings contained in the attached owners manualandThe tyres have been rotated and inspected by a participating tyre brand tyre retailer every 7,5. Mounting and Rotation Service Record has been fully completed and signedThere will typically also be a long list of what isnt covered. For example Road hazard injury e. Given that you really cant prove any of this, the guarantee is, therefore, worthless because it is left wide open to interpretation by the dealer andor manufacturer. For a good example, check out the Michelin warranty or guarantee pages 3 to 7 PDF. I used to link directly to the document on their website but it wandered around all over the place making it difficult to find wonder why So now a copy is hosted here. Dont be taken in by this its a sales ploy and nothing more. Nobody not even the manufacturers can guarantee that their tyre wont de laminate or catch a puncture the moment you leave the tyre shop. Buy your tyres based on reviews, recommendations, previous experience and the recommendation of friends. Do not buy one simply because of the guarantee. Big chain dealers vs. A reader pointed out to me that the dealer he worked for honoured tyre warranties in a no fuss manner requiring simply the original receipt for when they were purchased and one small form to be filled out. They then typically used a pro rated refund applied to the new tyre. For example if someone paid 1. They would either refund 3. I suspect this no fuss attitude is down to buying power. Large chain stores like Cost. Co or Sears will have far more clout with the manufacturers than you or I with our 4 tyres. After all they buy bulk in he hundreds if not thousands. For the consumer, it makes them look good because you get a fair trade. They can argue the toss with the manufacturers later, leveraging their position as a bulk buyer in the market to get the guarantees honoured. Car tyre types. There are several different types of car tyre that you, the humble consumer, can buy for your car. What you choose depends on how you use your car, where you live, how you like the ride of your car and a variety of other factors. The different classifications are as follows, and some representative examples are shown in the image on the right. Performance tyres or summer tyres. Performance tyres are designed for faster cars or for people who prefer to drive harder than the average consumer. They typically put performance and grip ahead of longevity by using a softer rubber compound. Tread block design is normally biased towards outright grip rather than the ability to pump water out of the way on a wet road. The extreme example of performance tyres are slicks used in motor racing, so called because they have no tread at all. All round or all season tyres. These tyres are what youll typically find on every production car that comes out of a factory. Theyre designed to be a compromise between grip, performance, longevity, noise and wet weather safety. For increased tyre life, they are made with a harder rubber compound, which sacrifices outright grip and cornering performance. For 9. 0 of the worlds drivers, this isnt an issue. The tread block design is normally a compromise between quiet running and water dispersion the tyre should not be too noisy in normal use but should work fairly well in downpours and on wet roads. All season tyres are neither excellent dry weather, nor excellent wet weather tyres, but are, at best, a compromise. Wet weather tyres. Rather than use an even harder rubber compound than all season tyres, wet weather tyres actually use a softer compound than performance tyres. The rubber needs to heat up quicker in cold or wet conditions and needs to have as much mechanical grip as possible. Theyll normally also have a lot more siping to try to disperse water from the contact patch. Aquachannel tyres are a subset of winter or wet weather tyres and I have a little section on them further down the page. Snow mud or ice special winter tyres. Winter tyres come at the other end of the spectrum to performance tyres, obviously. Theyre designed to work well in wintery conditions with snow and ice on the roads. Winter tyres typically have larger, and thus noiser tread block patterns. In extreme climates, true snow tyres have tiny metal studs fabricated into the tread for biting into the snow and ice. The downside of this is that they are incredibly noisy on dry roads and wear out both the tyre and the road surface extremely quickly if driven in the dry. Mud snow tyres typically either have M S stamped on the tyre sidewall. Snow Ice tyres have a snowflake symbol. All terrain tyres. All terrain tyres are typically used on SUVs and light trucks. They are larger tyres with stiffer sidewalls and bigger tread block patterns. The larger tread block means the tyres are very noisy on normal roads but grip loose sand and dirt very well when you take the car or truck off road. As well as the noise, the larger tread block pattern means less tyre surface in contact with the road. The rubber compound used in these tyres is normally middle of the road neither soft nor hard. Mud tyres. At the extreme end of the all terrain tyre classification are mud tyres. These have massive, super chunky tread blocks and really shouldnt ever be driven anywhere other than loose mud and dirt. The tread sometimes doesnt even come in blocks any more but looks more like paddles built in to the tyre carcass. Tyre constructions. Software To Remove Write Protection From Pen Drive.

Radial tyres wear much better and have a far greater rigidity for when cars are cornering and the tyres are deforming. Cross ply components. Radial components. The tread consists of specially compoundedvulcanised rubber which can have unique characteristics ranging from wear resistance, cut resistance, heat resistance, low rolling resistance, or any combination of these. The purpose of the tread is to transmit the forces between the rest of the tyre and the ground. The sidewall is a protective rubber coating on the outer sides of the tyre.
