Weather Station on Wheels (Vehicle Sensor Maintenance)

You probably never thought about it, but your vehicle is like a rolling weather station.  It can check the outside temperature, let you know when the roads are slippery and help you deal with rain. And how it does all those things is pretty cool.

First, just like any weather station, a vehicle has sensors that measure the driving and weather conditions you find yourself in.  Some of those sensors can control computerized systems in your vehicle to react to the weather.  It depends on whether you have a 2-wheel, 4-wheel or all-wheel drive vehicle how those sensors will respond.

Let's start with temperature.  Most vehicles now have a thermometer that measures the temperature outside.  It's usually in the front, and likely will tell you on the instrument panel what the outside temperature measures.  But a temperature sensor will also tell your vehicle's computers to turn on or off certain systems like the heating or air conditioning.  If your ambient temperature sensor isn't working right, some symptoms are a malfunctioning automatic A/C or a temperature display that is way different than the app on your phone says it should be.

Your vehicle will also have sensors that measure your speed at each wheel.  They work with an onboard computer to measure slippage in any of the wheels so traction control and antilock brakes work correctly in case of slick roads.

Your vehicle can measure something called longitudinal and latitudinal acceleration, and it uses a yaw sensor to do it.  That helps it determine if you might be in an oversteering or understeering situation.  It's important because it works with your vehicle's brakes to apply stopping power to keep you in control.

A steering wheel sensor tells the vehicle's computers what the driver is doing with the wheel.  It also can work with those wheel sensors to measure how slippery the roads are, whether it be due to a wet (rain) or granular (gravel or sand) surface.  By sending different torque or braking to each wheel, it helps the driver maintain control.

More and more vehicles now have a rain sensor that can turn on the wipers automatically when they measure precipitation on the windshield.

So, you're driving your own weather station, and making sure all this data is coming in properly depends on how each component is working.  Regular service and maintenance on these systems is important to make sure they can do their job. Your rolling weather station can't predict the weather, but it can sure help you deal with it, so help it do its job right.

Free Money (Almost) (Fuel Saving Tips)

You spend a lot of money on a vehicle, probably the most money you'll spend on anything except a house.  But the spending doesn't stop after you've bought it.  It goes into things like insurance, repairs and fuel.  One good piece of news is that you can cut down the amount you spend on fuel if you follow a few tips.

Keep your speed under 50 mph/80 kph.  Anything over that and your fuel economy will go down quickly the faster you go.  Sure, you can legally drive  faster than that, but practice this one tip and it can save you from 7%-14% on fuel.

Use cruise control.  The steady speed increases fuel economy by avoiding unnecessary braking and accelerating. 

If your vehicle is carrying unnecessary weight, unload it.  If you can save 100 pounds/45 kilograms, it can save you 1% of your fuel. 

Don't idle.  Let's say you're sitting in a parking lot with your engine running for 10 seconds.  Any more and you're wasting fuel.  Turn off your engine and start it when you have to get going.  You may have noticed that many newer vehicles automatically turn the engine off when the vehicle stops.

Avoid using a roof rack.  A cargo box strapped on the top of your vehicle can reduce your fuel economy by 2%-8% in city driving, by 6%-17% on the highway and by 10%-25% at highway speeds over 65 mph/105 mph.

Also, if you have roof rails on your vehicle with crossbars, you can save 1% of fuel simply by storing them somewhere else.  Some vehicles like Chrysler's Pacifica minivan allow you to store the crossbars inside the roof rails to reduce drag.

Keep tires at their recommended inflation.  It can save you 3% of your fuel bill.

Use the right motor oil for your vehicle.  Using the wrong kind can cost you 1%-2% more money on fuel.

Sure, many of those savings are small on their own.  But add them up and you'd be surprised at how much you can save.  Also, keep in mind that a well maintained vehicle will also save you fuel, so make regular maintenance trips to your vehicle service facility.
