EXECUTIVE VEHICLES ARE CHANGING - ESC

At one time, when bad things happened, it was all up to the driver to control the vehicle. The person holding on to the steering wheel made all the decisions. The driver was the algorithm that determined the outcome of the event.

Now computers control executive vehicles, and in an emergency scenario, accident, or vehicle violence, the executive vehicles rely on the computer algorithm to control the vehicle.

All security drivers need a firm foundation in defensive driving and vehicle dynamics. After all, if you can’t drive, you can’t escape a potentially dangerous situation.

Being a professional security driver means having the ability to drive out of a situation and having the knowledge to use the vehicle to its fullest potential, whatever the weather or vehicle type.

Many security drivers will use a different type of vehicle from on task to another, requiring them to understand the many intricacies and types.

security driver training and braking

We strongly suggest that anyone who attends a Security Driving training program is measured in accordance with Federal Motor Vehicle Safety Standard (FMVSS) 135. This is the standard that is used to measure vehicle braking performance. As a security driver, you must be able to perform at a much higher level than “minimum” (it is what you get paid to do).

Vehicle Static Stability Factor

Science of Security Driving

To ensure the safety and security of the principal, security drivers and secure transportation providers should understand that all vehicles have inherent characteristics that decrease the performance of the vehicle, and create a dangerous scenario for the principal. One of those characteristics is the vehicle’s static stability factor (SSF).

The Computer Chip in Your Butt

Computer chip in your butt

When a vehicle is approaching its limit of adhesion, a driver has two conflicting signals. The first signal is the steering wheel getting light, which means that it requires less effort to increase steering input (turn the steering wheel). The reason for this is that the adhesion the tire makes with the road is getting increasingly smaller – quickly.

The second signal is the vehicle load the driver feels at the back of the seat (their butt), which at the limit of adhesion is high.

Inaccuracies of Speedometers

Many times a driver is given 30 minutes to get to a destination that requires 45 minutes. So, at times, there is a tendency to drive a little faster than the speed limit allows. One of the questions we get asked is – “how accurate are speedometers”?

This is a promotional video of an upcoming series of online training. The series will discuss in detail the decisions that need to be made when selecting an executive vehicle. The ISDA online training are free for ISDA members and offered at a fee to non-members. All recorded webinars and materials will be available on the ISDA website long after the webinar.

Cold Weather and Tire Pressure

The polar plunge that has chilled much of the nation does more than bring out ice scrapers and antifreeze. It can trigger a vehicle’s tire-pressure-monitoring system overnight, sending nervous drivers to dealers and service centers.

For example, about 20 customers visited a Chevrolet dealership because their tire-pressure-warning icons were illuminated. Here’s why a cold snap affects tire pressure and sets off the tire-pressure-monitoring system (TPMS) warning lamp.

Tire Pressure Basics

Tire Pressure

Maintaining correct tire pressure helps optimize tire performance and fuel economy. Correct tire inflation pressure allows drivers to experience tire comfort, durability, and performance designed to match the needs of their vehicles. Tire deflection (the tread and sidewall flexing where the tread comes into contact with the road) will remain as originally designed and excessive sidewall flexing and tread squirm will be avoided. Heat buildup will be managed and rolling resistance will be appropriate. Proper tire inflation pressure also stabilizes the tire’s structure, blending the tire’s responsiveness, traction and handling.

Security Driver Triangle

Security Driver Triangle TM

Driving, any form of driving, is a balance, and that balance is called the “driving system.” The driving system is made up of three components: THE DRIVER, THE MACHINE, and THE ENVIRONMENT. In our world it is called the Security Drivers Triangle.

Electronic Stability Control (ESC) is a computer that takes over control of the vehicle when the vehicle’s path is not what the driver intended it to be. For those of us who have lost control of a car, we know that it’s that first twitch of the car that tells us that we are about to have an exciting experience. That twitch is information the car is sending to us. For some, interpreting this information is second nature, and for others it’s like trying to understand Swahili.
