SCANIA and Bosch have jointly developed an electronically controlled air braking system, the ELB, launched at Frankfurt this week.
Scania and Bosch have jointly applied for a patent for the system, which is not expected to be available in production vehicles for some time.
The principal advantage over a conventional system is that brake application time is considerably reduced, with Scania claiming a 50 per cent reduction.
Moreover, braking pressure to all wheels is applied at the same instant, regardless of the length of trailer.
Signalling between foot valve and wheel valves on the ELB system is done electronically by a microprocessor wired to a potentiometer at the pedal.
The system is piped like a conventional one, but this is just a back-up safety measure. If electronics should fail, the ELB will revert to conventional air pressure signalling.
Unlike a conventional. system, the ELB has no time lag between release of the brake pedal and brake release at the wheels.
