Another name for a Pedestrian Horn is Vehicle Sound for Pedestrians or VSP, though this is officially a Nissan name and developed system.Įdit: Matthew posted a link to an in depth description of ZOE’s VSP in the comments. While I haven’t touched it myself yet, I bet the sound selector push-button is wired directly to it.īy the way. It is hooked up to the Electro CANbus, power, and a few more wires. Basically an on-off switch, by International Rectifier, now Infineon: 7342 Hell, this horn is CD quality, they didn’t even use the PMW output of the main processor!!!! Also NXP. Enough for 2 minutes mp3 encoded data or 12 seconds of raw sound files. UJA1076AĢ5P16vpa: 16Mbit (2MB) flash memory, made by ST Microelectronics. It can also acts as a power supply and watchdog. UJA1076A: CAN transceiver, a nifty little chip, made by NXP. TPA3111Q1: A 10 Watt D-class (PWM) mono audio amplifier by Texas instruments. It has 64KB data flash, 20KB RAM, 256KB code flash, and a PMW generator. SPC5602: A generic processor, though aimed at the car industry, made by NXP. Here is a summary of the most important components. The horn is a bit hard to get to, one has to remove the front bumper to get to it. I feel sure Wilde would have loved the utility and beauty of what is officially called the ‘PB/5 Audio-Tactile Pedestrian Push Button Signalling System’.Dutch forum member OlafH dissected the pedestrian horn a bit and posted this picture. Somehow, the German automaker has managed to embody the essence of control, speed, and power into a sound. Third, it vibrates in different modes, so that sight- and hearing-impaired people can touch it and know whether to wait, or walk. The Porsche Taycan was a unanimous winner among car people and non-car people alike. Second, it acts as a microphone that gauges the ambient noise and raises and lowers the loudspeaker volume making it audible above background noise without being irritatingly loud. First, it acts as a loudspeaker to amplify the three different sounds. Third, the rapid tock-tocktock (the ‘WALK’ signal), repeated eight times a second, tells you to get moving.Īs part of the elegant design, a single transducer behind the circular upper half does three jobs. Second, the single baoooow noise (called the ‘change tone’) alerts you that something has changed. It is also planned to release for the Nintendo Switch at a later date. The frequency was specifically chosen to be clearly audible in city traffic. The Pedestrian is a side scrolling puzzle-platform game developed and published by American.

The bottom half has an enormous dished circular button. This is the same Push Button Frame (Black Frame & Back Plate only) as the PBF2-5X7-B but has a 9X12 sign back plate mounted to it for holding a 9X12 pedestrian sign. The semi-circular upper half has a large white arrow on a blue background. Low Profile Bulldog (Only) Push Button Frame (PBF2-9X12-B). You’ve seen it – a 25cm-high box with safe rounded edges bolted onto a traffic pole at a crossing. The PB/5, which was patented back in the 1980s, has all this under control. A switch for pedestrians has to be robust, elegant and intuitively easy to use by everybody – including pedestrians who are sight- or hearing-impaired.
