Bosch ABS/ESP 8.0
From assembly number 24275 onwards, a new generation of the integrated ABS/stability control system was adopted to replace the current Bosch ABS 5.7 system. The Bosch ABS 8.0 system integrates the following functions: ABS, EBD, ASR, MSR, ESP and Hill Holder. The various operation strategies of the system have remained unchanged. The only difference from the costumer’s point of view is improved comfort during ABS/EBD intervention thanks to a more refined system operation. Modifications with respect to Bosch ABS 5.7 system: • Basic functions have remained identical • Reduced weight by 25%: from 3 kg to 2,2 kg • Reduced dimensions by 30%: from 2,5 l to 1,6 l • Possibility to upload software updates. • Improved noise behaviour on account of new inlet valves and pump motor speed control. • Control of system pressure in ASR or ESP operation by PWM control of the electrovalve and failsafe monitoring. • Submersible HU due to tight accumulator design and sealed motor. • Improved performance of integrated ECU. • Introduction of the Hill Holder function.
