More analogue than digital!

barura

I've noticed these days a lot of cars have electronic controlled accelerators and brakes, which operate a servo instead of a cable that used to do this. To me it just seems like more points of failure!

Is there any car these days that has physical connections to the throttle, brake servo, etc?

I'm a bit paranoid of electronics handling stuff sometimes. :pac:

Passenger Boeing and Airbus planes have been fly by wire for donkeys years.

Mechanical/hydraulic systems can fail too!

Rover had fly by wire on their intercooled l series in the mid to late 90s, nothing new really, reliable too.

.... and of course, as most of these systems would have potentiometers they are analogue rather than digital :cool:

cables and chains strech, need tighetning and have no failover procedure. Drive by wire systems can have automatic tests, backup sensors and failover circuits, they can self calibrate and stay just as accurate as the car ages
