Actually, engine braking was part of the problem. When you press the (electronic) brake pedal lightly, it doesn't use the brakes at all, but uses engine braking whilst capturing the returned energy to charge the batteries. When you need to brake more, the actual brakes take over. It was the transition that was sometimes getting screwed-up, allowing the cars to cruse without brakes for a little while. At least that's what I heard.

No, engine braking is when you downshift and cause the combustion engine to rev up without getting extra fuel. The energy of braking goes into compressing air in the cylinders, but since there's not extra fuel to ignite it, it just disappears, and the car slows down.

In a hybrid vehicle, pressing lightly on the brakes applies regenerative braking, where the transmission is connected to one of the motors, which is used as a generator to slow the vehicle while recharging the battery.

I hadn't heard of a problem with the brakes, though, just with the electronic accelerators getting stuck.


Apparently there's a minor problem with the ABS where although it works it doesn't quite work as you'd expect.
Toyota wrote:Some owners have reported experiencing inconsistent brake feel during slow and steady application of the brakes on rough or slick road surfaces when the anti-lock brake system (ABS) is activated in an effort to maintain tire traction.
But considering the fact that my car doesn't even /have/ ABS, I don't see what people are crying about...

Confirming "Hare Dryer" as a Bugs Bunny reference.

I thought the Bobcat with a Pogo Stick was Felix the Cat, but my Google Fu failed to turn up anything. Other possibilities include Bubsy Bobcat and Bonkers D. Bobcat.

The Prius has never been available with a manual transmission. Honda stopped making the Civic Hybrids with manual transmissions in '05.

One of the comments to yesterday's Calvin and Hobbes cartoon points out that Hobbes leaves footprints in the snow, by the way. I wonder whether that cartoon inspired Randall in some way or it's a coincidence. I guess they must be imaginary footprints in Calvin's mind.

I believe the hair dryer is a reference to the scroll-over text, "Or is it a hare dryer?"

Just so we're clear, that cartoon was published on the first of January, 1989. There have not been any new Calvin & Hobbes comics since December 31, 1995.

Why would a manufacturer make a car for mass-market without a manual transmission? I'm sick of getting stuck behind people crawling up-hill because if they go any faster their gearbox will shift up, where they don't have the power to keep going... And when something goes wrong the 'driver' has no control over their car. Thanks Toyota for proving the point of a manual transmission...

The only "hare/hair" joke I remember from Bugs Bunny is from "Rebel Rabbit" (1949) where the southern Senator demands "This HARE must DYE!" after Bugs has gone on a rampage across the country.

http://en.wikipedia.org/wiki/Rebel_Rabbit

Either way "hare dryer" is not a bad joke in itself.

The Prius, along with the Lexus hybrids, features a continuously variable transmission, and always has. This negates the 'shifting when going uphill' problem you just described. The design of the transmission allows the electric and internal combustion systems to connect together without any further intermediate steps too, which is handy.

I don't think having a manual transmission would actually help with this problem though.

I'm kinda disappointed a lot of you seemed to be confused on the Higgs boson one!

I think we need more outreach!


The decay drawn in the last panel looks like it could be a 4 lepton Higgs decay. That'd be where the Higgs is created in a proton proton collision, perhaps by gluon fusion, then decays to two Z bosons, which in turn could decay into any lepton-antilepton pair. The decay drawn looks like a 4 muon decay (the prominent 4 straight lines), with the spirally tracks being not too interesting low Pt tracks...

In a detector such as ATLAS (my experiment), you get hits in several layers of pixels, silicon strips and drift tubes, which then must be reconstructed into tracks. So the dots on their own are just unconnected hits. Probably just noise. (Note: only charged particles leave hits in the tracking detectors)

The rest of the 'stuff' other than the leptons (in a 4 lepton Higgs decay), would just be fragments of the initial proton-proton collision. If the Higgs was created by gluon fusion, the other parts of the proton have to go somewhere!

(EDIT: Also just noticed the left most track which has a secondary vertex, where a particle has decayed after travelling some distance.)

Hurray for Calvin & Hobbes references! When I was a kid I cut the whole transmogrifier story line out of the newspaper one day at a time (going back from about day 3 when I realized it was going to go on for a while) and taped it to my bedroom wall. I had all the dialogue memorized.

Aside from the continuously variable transmission, they might do it anyway because automatics are hugely more popular in America than manuals. Depending on the target market, it might not be worth it to them.

I started lolling at the moose and squirrel, and loved the Higgs panel and all, but the beauty of this comic for me is the different box prints between the transmogrifier and duplicator. Well done, Randall.

Slightly disappointed there's been no full consensus on Ralph S Mouse, the hare dryer panel, or the pogo-ing bobcat. I'll check back later to see if people have done the rest of my thinking for me.

RE: Longcat - maybe the animal is running. It's not unheard of for quadrupeds to leave footprints the length of their body whilst in full sprint. Granted, it should have resulted in 2 sets of prints in close succession, but they may have the incredible ability of placing their hind feet in the same space as the fore. :D

#5 is probably a reference to my neighbor's dead rabbit.

It had been eating at me every time I saw xkcd in my iGoogle page, and I couldn't settle with it being a straight forward reference to Loony Toons/Bugs Bunny. Or even just a nice pun in the alt text.

Searching for hare dryer quickly came back with a possibly relevant urban legend at snopes.

I drive an '07 Prius. The regenerative braking has been explained. There is also a fairly useless "engine braking" mode on the shifter which supposedly allows traditional engine braking (forcing the internal combustion engine to go faster than it would with a given throttle setting). By "fairly useless" I mean it didn't seem to make a whole bunch of difference when I tried it, but then my regenerative system was working properly. The brake problem as I heard affects only some 2010 models, and is a bit hard to understand. I initally thought it was normal ABS operation misundertood by drivers (if the brakes are applied, and the vehicle hits a region of lower friction or has lower effective weight (ice/pothole) the wheel will lock and the ABS system will drop the pressure in the system until the wheel spins). But a Toyota forum member said no, it was a delay between the regenerative braking when the pedal is first applied (light braking) and normal friction braking when the pedal is depressed further. There's talk of a software bug; maybe if the ABS has just triggered on a pothole, and now requires longer pedal travel because of the pressure drop, the engine management doesn't realize and stops regenerative braking too early. Hard to find real data among all the FUD and hype.

I did wonder, as it's "snow tracks", if it was a dig at the winter performance of the low-rolling-resistance tires standard on the Prius, but the brake issue is the obvious candidate.

You make a good point. That chessboard would be quite the occupational hazard.

To be honest, it was less "modifying it for this knight's sake" and "getting it done quickly so that the post I was replying to wasn't several pages back, with multiple people beating me to the explanation"... I think an even square grid would fit, if I'd taken the time to draw one.
