EAP Curve Speed Adjust

by Clemens

Description

When no cars are in front going around a curve, speed up to the speed limit a bit sooner before coming out of the curve.  This might be done with mapping data and/or camera information.

TACC Speed Limit Shift

by Clemens

Description

Currently the TACC enters the speed change at (or short after) the speed limit sign. Especially when speed limit is reduced the speed should be within the limits when the car passes the sign.

It would also be great to have manual settings for number of feet in advance or past of a speed limit reduction, and number of feet before or after a speed limit increase, that the vehicle adjusts to the new speed.

Competitive/Pricing/Notes

Some more recent European cars implemented some of this.

Valet Speed Limit Setting

by Paul S

Description

Allow the car’s owner to set an optional Valet Speed Limit, so that the Valets could not exceed a certain speed.

Competitive/Pricing/Notes

This could be a useful theft deterrent, so that if the fob accidentally fell into a thief’s hands, he couldn’t get very far, without calling attention to his slow speed getaway.

Show Changed Target Speed

by youpidou

Description

When changing the target speed with the cruise/TACC stalk, briefly display the target speed as a number (perhaps by temporarily replacing the current driving speed in a different color). The small, hard-to-read triangle on the scale is not easy to see the exact setting.

Competitive/Pricing/Notes

My previous car, a BMW X1, had this feature and I found it very useful. It’s easy to lose track of the current target speed especially when having to deal with many speed limit changes (roadworks in summer…).

Improve Font Contrast

by Malcolm

Description

Improve contrast of characters used for the current speed.

Competitive/Pricing/Notes

The font has been made larger for better visibility. But, it’s still dark gray on a light gray background. If the font was changed to black it would be more visible which is needed when driving 70 mph and you only dare to glance at it.

Description

Although Tesla used the same stalk for cruise control as Mercedes, for some reason they only implemented half of it. The Mercedes cruise control can also be switched to speed limiter mode which sets a maximum speed rather than a minimum, actually providing a much easier to use (and safer) alternative to classic cruise control. It’s the one feature I would hate to give up when switching to a Tesla. Especially when driving faster than average traffic, using the limiter is much easier than constantly switching cruise control off/on whenever you have to slow down for traffic.

While cruising at a constant speed, the only difference between CC and limiter is the position of your foot. On cruise control, you tuck your foot somewhere away from the pedals (not exactly ideal for reaction time). On the limiter, you keep your foot resting on the accelerator (which is not fatiguing since you don’t have to modulate it, the weight of your foot is sufficient). In both cases the car behaves exactly the same: it simply modulates engine power to maintain the set speed.

The big difference is when you need to slow down for traffic.

On the limiter, you just ease your foot off the accelerator pedal to let the car slow down at whatever rate you choose, anticipating as much as you like. You then just follow traffic by modulating the accelerator as you normally would. When the road clears again, you press the pedal down to accelerate as smoothly or quickly as you like. As soon as you approach cruising speed again, the car smoothly reduces the acceleration and maintains the set speed (which you can always override, obviously). No need to switch anything off/on, no need to touch the stalk, real one pedal driving.

Compare this to cruise control: when there’s traffic, you either toggle the stalk several times to select some lower speed (which you then have to frequently adjust again as the traffic does not maintain a constant speed), or switch it off entirely. Deceleration rate is whatever the engineers chose for you and is relatively abrupt on most cars (I haven’t tried in a Tesla). Afterwards, when the road clears, you want to get back to cruising speed so you either hit the stalk several times again, or hit “resume”. The car now abruptly accelerates, again at whatever rate the engineers happen to have chosen for you, until you reach cruising speed. One pedal driving? No, one foot going on and off the pedal plus lots of left hand toggling and an uncomfortable experience for passengers.

On the limiter, I can drive hundreds of miles in and out of traffic without hitting any levers or touching the brake. With cruise control, you’re constantly adjusting it or switching it off and on. I was recently forced to use a classic cruise control and the constant toggling drove me nuts.

There are also a few safety issues where the limiter is, in my opinion, safer than cruise control:

1. Since you have to switch off cruise control when slowing down for traffic (or constantly modulate the speed up/down), you may end up distractedly following that traffic even as it slowly accelerates above your normal cruising speed without you noticing it. This way, I have actually ended up driving 180 km/h instead of my normal 160 km/h cruising speed (which is already well above the legal limit). 160 is just a fine (I like to call it a speed tax), but 180 is an immediate driver’s license revocation in my country. With the limiter engaged, there’s no such risk. You keep following the car in front in a natural way until it gets too fast, at which point the limiter automatically keeps you from absentmindedly speeding more than you intended.

2. Switching off cruise control or selecting a lower speed is a deliberate action with a slightly higher psychological threshold than simply easing your foot off the accelerator. When driving a car with cruise control, I often find myself going faster than I should in certain situations (cars in front doing funny things, bends in the road)  because one tends to hesitate a bit before switching off CC or hitting the brakes. When cruising on the limiter, it’s much more natural to just ease off on the pedal a little bit and gently slow down. Then, when everything is safe again, you smoothy accelerate withouth ever having had to hit a switch or move your foot to a different pedal. Whenever something on the road makes me uncomfortable, I often notice that I had already slowed down without realizing it. Not so on cruise control, where I would still have been cruising at the same speed. This is probably the reason why we even have road signs warning people to switch off CC when approaching road works.

Competitive/Pricing/Notes

On Mercedes cars, the tip of the stalk is used to switch between cruise control and limiter. The yellow light next to “LIM” comes on when the limiter has been selected. Tesla has assigned a different function to the tip and the light, and removed the letters “LIM” (even though they are still displayed in the photo in the manual last time I checked, and probably present in early models), so I would suggest adding the option to the touchscreen instead. Just an extra toggle switch in the menu: “Cruise Control” / “Speed limiter”. This should be a simple software update.

Automatic Steering Mode Select

by Carl

Description

Offer the ability to have the car automatically select between different steering modes based on speed. This would change between Comfort, Standard and Sport modes.

When the speed exceeds the “Standard Threshold”, the steering mode automatically switches from Comfort to the Standard setting and returns to Comfort below that speed.

When the “Sport Threshold” is set to a value above Standard threshold, the steering mode automatically switches to the Sport setting whenever the vehicle speed exceeds that level and returns to Standard below that speed.

Competitive/Pricing/Notes

This feature can easily be implemented in software, similar to the automatic speed settings currently available for the Smart Air Suspension.

Instead of a slider for fan speed, I think buttons would be better. Just one tap and this ramps up to the desired speed. Many times I hit a bump while sliding or totally miss the slider button

Software change.

It’s great that the car lowers above a certain (now configurable!) speed, and lifts up again when speed falls under a certain limit.

Steering:
Similar to the ride height, the user should be able to determine when the steering should change from Comfort to Standard or from Standard to Sport. My personal preferred setting would be: Sport above 130 km/h, Standard below 60 km/h, Comfort never.

The suggestion is the result of driving 1,400 km over the weekend. This would model the real world behavior that I noticed while actually traveling with Model S.

Panoramic roof:
– If panoramic roof is open, it should move to vent position above a certain speed.
– If panoramic roof is open or in vent position, it should close above a certain speed.
– As a bonus, panoramic roof could move into vent below a certain limit.

Disable Speed Limiter

by RaceDeck

Description

Would be great to have not have a factory speed limiter on the car. We do a number of sanctioned events where we can drive at max speeds ( controlled / legal) and would love to see what the limits are.

Competitive/Pricing/Notes

From Moderator: The speed limiter may be to protect the motor, which is running at about 16,000 RPM at 130 MPH.  This is similar to an ICE car’s tachometer red-zone where the engine is at risk of self-destruction at high-RPMs.

Status

From Moderator: Interestingly the v5.9 software increased the maximum speed indication on the instrument display to 140 MPH, so perhaps a small speed upgrade is in the works.

Safety Camera Database

by cwhite262

Description

There are databases of safety/speed cameras. On most Garmin GPS units, you can buy a subscription to the location of safety cameras. When approaching a fixed position safety camera, the nav system gives you an audible alert and visual indication of speed.

Competitive/Pricing/Notes

To implement this feature you need the ability to integrate safety camera database into the nav system.  A Garmin subscription was $25/year but was discontinued in 2020.

Phone Speed Dial

by Moderator

Description

Currently finding a commonly used phone number is a painful affair, require many button clicks to locate and dial a specific number from the contacts list (when the contact list is large).

Allow any contact phone numbers to be dropped into a specific speed dial button (with a default to the next empty location).  Include a separate pane for one-button touch of speed dials. Each button shows the contact’s name and number.

A bonus would make it easy to select speed dials from the steering wheel – perhaps showing in the right-pane of the instrument cluster and allowing the scroll wheel to scan and select.

Competitive/Pricing/Notes

This feature is available on most cars that have integrated bluetooth phone connections.

Description

A basic option uses a pre-set limit for warning and/or preventing going a specific speed.

To deactivate and change the setting requires a password.  Activation would not require a password. Settings and operation can only be changed while stopped.

This might be used as a parental limit for the kids or as a valet mode where the maximum speed is limited.

A more advanced mode would read the GPS location and identify the speed limit and provide a warning when the speed exceed the map’s known speed limit by a set amount. For locations outside known roads (i.e. parking lots), it might limit speeds to 20 MPH.

Competitive/Pricing/Notes

Unknown if other vehicles have such an option.  Using GPS positioning is not 100% reliable, especially when frontage roads run along a freeway or other close roadways.

Status

The speed warning feature is being added as a standard item in the late September to October 2014 time-period.
