• Robert Bosch, the German component and automotive systems maker, is developing an electronic package designed to prevent jack-knifing and other sideways slewing skids.
Vehicle Dynamic Control combines existing ABS brake and ASR traction control hardware: Bosch says it is at an "advanced stage of development".
An on-board computer monitors vehicle behavior and applies power or braking to individual wheels as necessary Drive is directed to one side by braking the opposite wheel, forcing a reaction through the differential.
The system could work well in commercial vehicles says Norbert Rittmannsberger, head of chassis and safety systems. "But the truck industry is very price sensitive," he adds. 'Manufacturers' priority will be to introduce disc brakes first.".
ELB, the computerised brakeby-wire system being developed with Scania, is thought to be especially important to the success of the Bosch system in LGlis. Its instantaneous signaling minimizes cycle times, allowing the system to react faster than the changing circumstances of the incident, says Bosch. This would help avoid over-correction.
The system will be ready for series production from 1996; Bosch says that field trials are progressing well,.
