Bendix Commercial Vehicle Systems offers six-channel antilock braking systems for motor coach and truck applications. The Sentinel system features technology from Bendix's global joint-venture relationship with Knorr-Bremse in a 6S6M ABS configuration (six wheel speed sensors and six modulators that transmit pulsating air when a wheel locks). The 6S6M configuration provides individual, all-wheel ABS control on three-axle or tag-axle vehicles.
All-wheel control gives drivers braking control in slippery road conditions with shorter stopping distances and better brake-in-lane performance. Individual tire control also provides better split-coefficient performance — situations in which one tire stops on water or ice and another tire stops on dry pavement — by allowing the ABS to respond to each tire individually. Enhanced braking control also minimizes tire flatspotting.
The Sentinel six-channel system provides two traction options. An automatic traction control feature senses individual wheel slippage even before brakes are applied, adjusting driver torque of the axle to the other wheels to control slipping. An in-cab manual control switch improves traction in off-road, slow speed, soft-soil conditions.
Operators have two diagnostic options: blink code technology or hand-held MPSI Pro-Link diagnostics. Other features include:
Modular ECU design that can be mounted on the frame or in the cab.
12-volt, metal modulator with integral connectors.
Sealed, high-signal strength sensors with metal heads.
The Sentinel six-channel ABS complements Bendix's existing ABS line for power units, which now includes 4S4M, 6S4M, and 6S6M systems. For more details, contact Bendix, 901 Cleveland St, Elyria OH 44035.
