This article reports on a Continental Teves compact class demonstration vehicle (the “30m-car”) that uses a control network of selected, in part newly developed chassis systems to show a solution helping “Mr. or Mrs. everyday driver” to shorten their entire stopping distance (normal reaction distance plus brake force build-up distance plus braking distance) in emergency braking situations. The car is fitted with special concept tires with magnetized sidewalls that communicate with the newly developed SWT (Sidewall Torsion) Sensor, a brake-by-wire electro-hydraulic brake system and an electronic chassis system with controllable airsprings and hydraulic shock absorbers. The driver’s reactions are monitored by accelerator and brake pedal sensors, an ACC distance sensor unit serves to monitor the traffic in front of the vehicle. All chassis subsystems were cross-linked within one control network.
