Product Specification 8-Channel Anti-Lock Brake Control Description The MICO 8-channel ABS ECU enhances the effectiveness of a traditional full power hydraulic brake system by providing added vehicle safety for multi-wheeled vehicles operated both on and off-highway. ABS can improve vehicle control during braking and reduce stopping distance on slippery (split or low coefficient of friction) road surfaces by limiting wheel slip and minimizing lockup. Reducing wheel slip improves vehicle stability and control during braking. The ABS ECU interfaces with 8-speed sensors to monitor wheel speed, pressure transducers for diagnostics, and 8 electrohydraulic ABS valves to proportionally control brake pressure. The brake control system along with the physical braking system can help vehicle manufacturers meet ECE 324 R13 and European Machinery Directive 2006/42/EC and are designed to help achieve SIL 2 (Safety Integrity Level 2 according to IEC 61508) and PL-d (Performance Level d per ISO 13849-1) standards. This system is designed to handle 8-channel ABS control. ABS ECUs for 2, 4 and 6-channels of hydraulic ABS (HABS) control are also available from MICO. In addition to these basic components, other inputs and outputs can be added to the system. For example: ABS and brake warning indicator lamps can be added to the outputs of the ECU. The MICO 8-channel ABS ECU is fully compatible to the SAE J1939 CAN communication standard (sub standards: 11, 21, 71, and 73). MICO is a trademark and registered trademark of MICO, Inc. MICO is registered in the U. S. Patent and Trademark Office as well as in Australia, Canada, Indonesia, Japan, Peoples Republic of China, South Korea, and the European Community.
