| 摘要： | The increased use of electronic braking performance monitoring systems (EBPMS) is deemed to be acceptable by DVSA in the latest version of its Guide to Maintaining Roadworthiness. The guide goes on to add that from April 2025 there will be 'an expectation' that a laden roller brake test or EBPMS will be the only acceptable methods of assessing braking performance in most cases. It stresses, however, that a roller brake test will still form part of the annual heavy commercial vehicle MOT test. EBPMS can only be fitted to a trailer, and not to a truck. However it can monitor the combined braking performance of both the trailer and the tractor unit hauling it, says BPW, which has played a prominent role in developing the technology. "It's a software-based system which continuously monitors the air brakes by combining the data from the electronic braking system (EBS) with data from the telematics system in order to calculate the change in speed over distance and time to determine the deceleration rate," says engineering manager Roger Thorpe. The data it collects is transmitted to idem's servers using GPRS, can be accessed through a telematics portal or smartphone app, and can then be used to generate performance reports. The software employed enables a braking efficiency figure to be produced which can be compared to an equivalent figure from a laden roller brake test (pictured below), BPW states. the vehicles concerned to one roller brake test annually rather than the four adopted as best practice in recent years, resulting in useful cost and downtime savings. |
